Abstract
BACKGROUND The clinical value of ascitic fluid pH or lactate in the diagnosis of spontaneous bacterial peritonitis was debated in alcoholic cirrhosis. It was rarely discussed in hepatitis B-related cirrhosis. We investigated the best rapid diagnostic method in spontaneous bacterial peritonitis of patients with hepatitis B-related cirrhosis. METHODS Ascitic fluid polymorphonuclear cell count, ascitic fluid pH, arterial-ascitic fluid pH gradient, ascitic fluid lactate, and arterial-ascitic fluid lactate gradient were analyzed in 79 patients with sterile portal hypertension-related ascites, 31 patients with spontaneous bacterial peritonitis, 16 patients with hepatocellular carcinoma, 15 patients with malignancy-related ascites and 9 patients with other miscellaneous diseases. RESULTS The sensitivity, specificity and accuracy of the diagnosis of spontaneous bacterial peritonitis were 100, 94 and 95% with the cut-off value of an ascitic fluid polymorphonuclear cell count > or = 250 cells/mm3, and were 86, 98 and 96% with that value > or = 500 cells/mm3, respectively. The sensitivity, specificity and accuracy were 29, 92, 80% using ascitic fluid pH < or = 7.35 as a cut-off value; 38, 91, 82% using arterial-ascitic fluid pH gradient > or = 0.1 as a cut-off value; 52, 92, 85% using ascitic fluid lactate > or = 32 mg/dL as a cut-off value, and 38, 96, 85% using arterial-ascitic fluid lactate gradient > or = 20 mg/dL as a cut-off value. CONCLUSIONS The sensitivity of ascitic fluid pH or lactate was too low to aid in a diagnosis of spontaneous bacterial peritonitis in hepatitis B-related cirrhosis in spite of the acceptable specificity. An ascitic fluid polymorphonuclear cell count > or = 250 cells/mm3 or > or = 500 cells/mm3 was the major and appropriate aids in the rapid diagnosis of spontaneous bacterial peritonitis.

Abstract
To define patients with an ascitic fluid polymorphonuclear cell count > or = 250 cells/mm3 or > or = 500 cells/mm3 but without spontaneous bacterial peritonitis, 166 patients with sterile cirrhotic ascites, 46 patients with spontaneous bacterial peritonitis, 123 patients with hepatocellular carcinoma, 67 patients with peritoneal carcinomatosis or massive liver metastasis and 12 patients with other miscellaneous diseases were studied. The sensitivity, specificity and accuracy of the diagnosis of spontaneous bacterial peritonitis were 100, 86 and 88% with the cut-off value of an ascitic fluid polymorphonuclear cell count > or = 250 cells/mm3; and were 93, 91 and 92% with that value > or = 500 cells/mm3, respectively. With the cut-off value > or = 250 cells/mm3 or > or = 500 cells/mm3, the prevalence was 18% or 14% in hepatocellular carcinoma; and 30% or 19% in peritoneal carcinomatosis or massive liver metastasis. The ascitic fluid lactate concentration was insensitive and nonspecific. Among the patients with an ascitic fluid polymorphonuclear cell count greater than the cut-off values, an ascitic fluid erythrocyte count > or = 10,000 cells/mm3, a ratio of ascitic fluid erythrocyte to total leukocyte count > or = 100, and the ratio of ascitic fluid polymorphonuclear cell to total leukocyte count < or = 75% indicated hepatocellular carcinoma, while serum to ascites albumin gradient < or = 1.1 g/dl and a ratio of ascitic fluid polymorphonuclear cell to total leukocyte count < or = 75% indicated peritoneal carcinomatosis or massive liver metastasis.

Abstract
The effects of reserpine were investigated in two models of portal hypertension in rats. Twenty-four hours after 1 mg/kg of reserpine was administered intraperitoneally to normal and portal vein stenosed rats, the cardiac index, mean arterial pressure, heart rate, and portal pressure were significantly decreased compared with normal and portal vein stenosed rats receiving placebo. In addition, the portal tributary blood flow was significantly decreased in portal vein stenosed rats receiving reserpine, but was unchanged in normal rats. In cirrhotic rats receiving a single dose of reserpine, 0.1 mg/kg intraperitoneally for 24 h, there were significant decreases in cardiac index, mean arterial pressure and heart rate compared with cirrhotic rats receiving placebo, while the portal pressure and portal tributary blood flow followed a decreasing trend after reserpine administration. The degree of hemodynamic change was similar in the groups of rats receiving reserpine, even though cirrhotic rats received lower doses than either normal or portal vein stenosed rats. This study suggests enhanced sympathetic nervous activity observed in cirrhotic rats.

Abstract
One hundred and fifty cirrhotic patients with or without esophageal varices and/or gastric varices were investigated by endoscopy and hepatic venous catheterization to evaluate differences in the degree of portal hypertension, main portal venous diameter and frequency of portal systemic encephalopathy. Hemodynamic values were correlated with varices size as assessed by endoscopy. Patients with large gastric varices had wedged hepatic venous pressures and hepatic venous pressure gradients which were lower than patients with esophageal varices only, but similar to patients without varices. In addition, in patients with large gastric varices, a decrease in the diameter of the main portal vein and an increase in the incidence of chronic portal systemic encephalopathy were noted. Our results implied that patients with large gastric varices presented different hemodynamic features including the degree of portal hypertension and the incidence of portal systemic encephalopathy from patients with esophageal varices only.

Abstract
Variceal recurrence and rebleeding are common after initial obliteration by injection sclerotherapy. To investigate whether propranolol can maintain variceal obliteration by sclerotherapy, 59 patients with oesophageal variceal bleeding after sclerotherapy were enrolled. Patients were allocated to propranolol treatment (30 patients) or served as controls (29 patients). After a mean follow up of 2 years and 4 months, 53 patients completed the study. Fifty-eight per cent of the propranolol group versus 77% of the control group experienced recurrent varices (P = 0.20). Fifteen per cent of the propranolol group versus 11% of the control group developed cardiac varices. Recurrent variceal bleeding was encountered in 27% of the propranolol group and 19% of the control group. Three patients in the propranolol group, compared with two patients in the control group, died of massive variceal bleeding. Eighty per cent of them bled from cardiac varices. Both groups had similar survival rates. We therefore concluded that the use of propranolol after variceal obliteration by sclerotherapy can neither prevent oesophagogastric variceal recurrence nor prevent further rebleeding.

Abstract
Serum pepsinogen I (PGI) levels were measured in 231 duodenal ulcer (DU) patients and 100 sex- and age-comparable healthy controls. Significantly higher mean serum PGI levels were found in DU patients than in controls (124.7 +/- 3.4 ng/ml v. 92.9 +/- 2.3 ng/ml; P < 0.001) (mean +/- SE). These levels were higher in male DU patients than in female DU patients (128.5 +/- 3.9 ng/ml v. 107.4 +/- 6.4 ng/ml; P < 0.05). Smoking was associated with elevated serum PGI levels in DU patients (145.3 +/- 5.1 ng/ml v. 109.0 +/- 4.2 ng/ml; P < 0.001). Healed DUs were associated with lower mean serum PGI levels than active ulcers (110.9 +/- 7.6 ng/ml v. 129.4 +/- 3.8 ng/ml, P < 0.05). Whether patients were positive or negative for Helicobacter pylori, infection did not affect mean serum PGI levels. All the risk factors for DU may not affect serum PGI levels and DU may therefore be considered a multifactorial disease.

Abstract
The effect of portal hypertension on plasma sex steroid levels was studied in 49 patients with hepatitis B virus-related postnecrotic cirrhosis. In accordance with the Child-Pugh classification, 18 patients were classified as grade A, 15 grade B and 16 grade C. At the same time, 25 males who were admitted for physical check-up served as normal controls. Serum testosterone levels decreased (3.31 +/- 2.03 vs. 5.65 +/- 0.13 ng/ml) and estrone levels increased (0.16 +/- 0.08 vs. 0.09 +/- 0.02 ng/ml) significantly in patients with cirrhosis compared to the levels obtained in the controls. Moreover, these changes were associated with an increased severity of cirrhosis (P < 0.05 when severity increased from grade A to C). Hemodynamic values regarding hepatic venous pressure gradient and cardiac output demonstrated significant differences in patients from grade A to C, but the correlation between these two parameters was poor (r = 0.3242). The hepatic venous pressure gradient, the only direct measurement of portal hypertension, did not correlate with any of the measured hormone levels in patients with cirrhosis. There was, however, a highly significant negative correlation between cardiac output and testosterone levels (r = -0.8754, P < 0.01) and a positive correlation between cardiac output and estrone levels (r = 0.7522, P < 0.05) in grade C patients. On the basis of these results, we concluded that gonadal dysfunction is a common finding in patients with hepatitis B related postnecrotic cirrhosis, especially in those with decompensated liver function. The relationship between cardiac output and severity of liver disease suggests that the degree of portosystemic shunting probably increases as liver disease worsens.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The pressure of oesophageal varices was determined by fine needle direct puncture in 19 patients with hepatitis B surface antigen (HBsAg)-positive cirrhosis after the first episode of variceal bleeding before endoscopic sclerotherapy. Both the stability and reliability of the measurement of intravariceal pressure by fine needle puncture were confirmed. Seven patients received intravenous 1 mL normal saline. Intravariceal pressure did not change before and after injection of normal saline (16.3 +/- 4.0 vs 16.0 +/- 4.0 mmHg, P > 0.05). Twelve patients received intravenous 1 units vasopressin and this caused a significant reduction in intravariceal pressure (15.6 +/- 2.6 vs 10.3 +/- 2.9 mmHg, P < 0.0001). The average basal intravariceal pressure in these patients was 15.8 +/- 3.1 mmHg. After intravariceal pressure was recorded, the needle was left in situ and endoscopic sclerotherapy commenced immediately. During the investigation, no adverse reaction or complication was encountered. It was concluded that the measurement of intravariceal pressure by fine needle direct puncture followed by immediate sclerotherapy is a safe and simple method to evaluate the short-term effect of drug prevention from oesophageal variceal bleeding and that vasopressin causes reduction of intravariceal pressure.

Abstract
Somatostatin has been used to effectively control acute variceal haemorrhage, with conjectured mechanisms on portal hypertension. We, therefore, evaluated the effects of somatostatin on hepatic and systemic haemodynamics in 15 patients with hepatitis B-related cirrhosis and portal hypertension. All patients received an intravenous, continuous infusion of somatostatin 250 micrograms/h, following a bolus injection of 250 micrograms. In systemic haemodynamics, the mean arterial pressure (MAP) increased (P < 0.05), associated with a reflex bradycardia within 3 min following bolus injections, compared with basal values. The right atrial pressure, pulmonary capillary wedge pressure, inferior vena cava pressure, cardiac index, and systemic vascular resistance remained unaffected after drug infusion. In hepatic haemodynamics, the wedge hepatic vein pressure remained unchanged after drug administration. However, there was an increase in free hepatic vein pressure (FHVP; P < 0.05), and a trend toward a decrease in the hepatic vein pressure gradient (HVPG; P = 0.063), within 3 min after bolus injection. Furthermore, the hepatic blood flow decreased significantly at 10 and 30 min after somatostatin infusion (P < 0.05). The effective sinusoidal perfusion assessed by indocyanine green infusion also decreased progressively at 10 min (P = 0.057) and 30 min (P < 0.05). We concluded that somatostatin, at the dose used in this study, caused a transient and bolus-related vasoconstrictive effect, resulting in increases in MAP and FHVP, a decrease in heart rate, and a trend toward lower HVPG. In addition, somatostatin reduced the hepatic blood flow and effective sinusoidal perfusion which may be hazardous to cirrhotic patients during variceal haemorrhage.

Abstract
Fifty-one patients (age 18-73 years) with acute myeloid leukemia were treated with daunorubicin, cytarabine, and etoposide in an age-adjusted protocol, with patients older than 50 receiving fewer days of therapy. Complete remission (CR) occurred in 66% of the patients (34 of 51 patients). Patients 50 years of age and younger achieved a 74% CR rate (23 of 31 patients) compared to a 55% CR rate (11 of 20 patients) in older patients. Of the 34 complete responders, 11 (32%) refused consolidation therapy and received traditional Chinese herbal medicine. All of these 11 patients relapsed after a short remission duration (median, 3.8 months) and died. The median remission duration and median overall survival of 23 complete responders receiving at least two courses of consolidation therapy were 10.1 and 19.8 months, respectively. The actuarial 3-year disease-free survival for these 23 complete responders was 21 +/- 9%. Myelosuppression was the major toxicity, and nonhematological side effects were acceptable. The regimen appeared to have acceptable toxicity, and its efficacy was comparable with that of standard regimens with long-term maintenance therapy.

Abstract
Two hundred and twenty-six patients with endoscopically confirmed duodenal ulcers > or = 5 mm in diameter entered a double-blind randomized trial comparing 20 mg omeprazole administered once daily in the morning with 300 mg ranitidine administered once daily at night. The patients were assessed endoscopically and symptomatically after 2 weeks, and those whose ulcers had healed terminated the study. Patients with unhealed ulcers continued treatment for a total of 4 weeks. Omeprazole produced significantly higher healing rates than ranitidine at both 2 weeks (57 vs 28%, P < 0.0001) and 4 weeks (93 vs 80%, P = 0.006). Similarly, significantly higher 'effective healing rates' (defined on the criteria established by the Japanese Society of Digestive Endoscopy) were observed with omeprazole compared with ranitidine at 2 and 4 weeks. After 2 weeks, there were significantly fewer reports of both day-time and night-time epigastric pain by omeprazole-treated patients compared with ranitidine-treated patients (22 vs 44%, P < 0.0001 for day-time pain; 24 vs 35%, P = 0.025 for night-time pain). Both drugs were well-tolerated and no major adverse effects were recorded during either treatment. In conclusion, 20 mg omeprazole administered once daily was superior to 300 mg ranitidine administered once daily for duodenal ulcer healing and symptom relief.

Abstract
This randomized controlled trial was conducted to compare the efficacy of intravenous infusion of octreotide (a synthetic long-acting somatostatin analogue) with vasopressin in 48 cirrhotic patients with endoscopically proven bleeding esophageal varices. Twenty-four patients received a continuous infusion of octreotide 25 micrograms/h for 24 h after an initial bolus of 100 micrograms and another 24 patients received a continuous infusion of vasopressin 0.4 U/min for 24 h. Bleeding was initially controlled after 6 h of drug infusion in 88% (21/24) and 54% (13/24) of the patients treated with octreotide and vasopressin respectively (p = 0.03). Complete control of bleeding after 24 h of drug infusion was achieved in 15 (63%) patients receiving octreotide and in 11 (46%) patients receiving vasopressin (p > 0.05). Side effects during drug infusion such as headache, chest pain and abdominal pain were significantly lower in the octreotide group (3/24) than in the vasopressin group (11/24). Serum gastrin and insulin levels fell significantly following octreotide infusion, but plasma glucose levels remained unchanged. Mortality related to bleeding esophageal varices was no different between the two groups. This report showed that octreotide infusion was more effective and had fewer side effects than vasopressin in initial controlling of acute esophageal variceal bleeding until an elective endoscopic sclerotherapy could be performed.

Abstract
Serum pepsinogen I (PGI) levels were measured in 192 gastric carcinoma (GC) patients and 70 controls. Among GC patients serum PGI levels were not influenced by the following variables: age, sex, smoking, Borrmann's or Lauren's classification, tumor size, cellular differentiation, and layer of invasion. The mean serum PGI levels of tumors restricted to the body, antrum, or involving both areas were 64.8 +/- 37.6 ng/ml, 76.0 +/- 47.0 ng/ml, and 51.1 +/- 25.5 ng/ml, respectively (P < 0.005). Odds ratios of GC patients from the quartile of 262 serum PGI levels in the limits > or = 100 ng/ml, 70-99.9 ng/ml, 45-69.9 ng/ml, and < 45 ng/ml were 1.00, 0.76, 3.44, and 37.1, respectively (P < 0.001). The lower serum PGI levels of Chinese GC patients seem to be related to disease location rather than other characters of the tumor.

Abstract
The influence of octreotide and somatostatin on liver metabolic activity were studied in 16 patients with cirrhosis that was positive for hepatitis B surface antigen (HBsAg). In patients receiving a 50 micrograms bolus and a 50 micrograms/hr infusion of octreotide, the hepatic blood flow, hepatic clearance, and the maximum velocity/metabolic elimination rate constant (Vmax/km) were significantly reduced after octreotide infusion compared with basal values. Similarly, the hepatic blood flow, hepatic clearance, and Vmax/km were significantly decreased in patients receiving a 250 micrograms bolus and a 250 micrograms/hr infusion of somatostatin. The extraction ratio and the systemic hemodynamic values, including cardiac index, heart rate, mean arterial pressure, and systemic vascular resistance, showed no significant changes in patients receiving either octreotide or somatostatin. These findings suggest that, as with somatostatin, octreotide reduced hepatic blood flow and impaired liver metabolic activity in patients with HBsAg-positive cirrhosis. These effects may have important clinical implications in the management of bleeding esophageal varices in patients with cirrhosis.

Abstract
The value of serum C-reactive protein, lactate dehydrogenase isoenzymes and erythrocyte sedimentation rate in predicting the outcome of acute pancreatitis was evaluated for 57 episodes in 54 patients. Serum C-reactive protein levels on day 2, 4 and 7 after admission were significantly higher in 19 episodes of severe attacks than in 38 episodes of mild attacks (13.71 +/- 9.68, 9.00 +/- 7.54, 6.02 +/- 3.83 vs 4.78 +/- 3.91, 3.30 +/- 3.61, 1.43 +/- 2.08 mg/dL; P less than 0.0001, P less than 0.005, P less than 0.0001, respectively). The sensitivity, specificity and accuracy of predicting a severe attack were 94, 76 and 82% using C-reactive protein greater than or equal to 8 mg/dL on day 2; 67, 92 and 84% using C-reactive protein greater than or equal to 5 mg/dL on day 7; and 59, 76 and 70% using Ranson's criteria greater than or equal to 3. Increases in LDH-4 and LDH-5 isoenzymes were found in both groups, with LDH-4 being slightly higher in severe attacks than in mild attacks. There was no significant difference of erythrocyte sedimentation rate between both groups. When compared with Ranson's criteria, lactate dehydrogenase isoenzymes and erythrocyte sedimentation rate, C-reactive protein is more valuable in the early assessment of the severity of acute pancreatitis.

Abstract
The hemodynamic effects of octreotide were studied in 20 patients with hepatitis B-related cirrhosis. In patients receiving a 100-micrograms bolus and a 100-micrograms/h infusion, heart rate, cardiac index, and systemic vascular resistance showed no significant changes, whereas right atrial pressure, pulmonary capillary wedge pressure, and inferior vena cava pressure decreased significantly after octreotide infusion compared with basal values. In contrast, in patients receiving a 50-micrograms bolus and a 50-micrograms/h infusion, all the systemic hemodynamic values were unaffected. In both groups of patients receiving two different doses of octreotide, the estimated hepatic blood flow, hepatic indocyanine green clearance, and wedge hepatic venous pressure were significantly reduced at 60 minutes after octreotide administration compared with basal values, whereas the hepatic venous pressure gradient remained unchanged. It is concluded that the two different doses of octreotide administration result in the reduction of the wedge hepatic venous pressure and the hepatic blood flow of a similar magnitude, whereas the hepatic venous pressure gradient is unaffected. Octreotide induces discrepant systemic hemodynamic response; this effect is dose related.

Abstract
To investigate whether Sengstaken-Blakemore tube tamponade is needed before emergency sclerotherapy, 60 patients with active esophageal variceal bleeding were randomized to receive either immediate injection sclerotherapy (group A) or sclerotherapy preceded by balloon tamponade (group B). Three patients in group A (10%) were completely inaccessible to sclerotherapy. Initial success in stopping bleeding at 24 hours after sclerotherapy was 76% in group A and 81% in group B (p = 0.89). Re-bleeding rate was 27% in group A versus 50% in group B (p = 0.11). Blood requirement was significantly less in group A (3.7 +/- 2.5 units vs. 6.2 +/- 3.2 units, p less than 0.01). Major complications were also significantly less frequently encountered in group A than in group B (14% vs. 39%, p less than 0.05). In-hospital mortality was 24% in group A and 42% in group B (p = 0.14). We conclude that the efficacy of immediate sclerotherapy is comparable to that of delayed sclerotherapy preceded by balloon tamponade. Additionally, significantly less blood requirement and fewer complications were noted in the immediate sclerotherapy group. Thus, emergency sclerotherapy without prior balloon tamponade is feasible and recommended in most patients with acute esophageal variceal hemorrhage.

Abstract
Two hundred and sixty-seven susceptible hospital personnel who had been randomly divided into three groups to receive different doses (5 micrograms, 2 micrograms or 1 microgram) of a plasma-derived hepatitis B vaccine on a four-dose schedule were investigated annually for 4 years. Of them, 251 were vaccine responders. The percentages of persistence of antibody to hepatitis B surface antigen (anti-HBs) in these 3 groups were 95.5% (84/88), 92.3% (72/78) and 95.3% (81/85), respectively (P greater than 0.05). During the follow-up period, 12 of 21 (57.1%) responders with low anti-HBs titres (10-100 miu/mL) and 3 of 48 (6.3%) responders with medium anti-HBs titres (101-1000 miu/mL) were found to be anti-HBs seronegative, while none of the 182 candidates with high anti-HBs levels (greater than 1000 miu/mL) lost their anti-HBs. The 4 year cumulative rate of natural booster in the responders was 11.6% (29/251). None of the candidates became HBsAg positive during the follow-up period. This study revealed that low dose hepatitis B vaccine can provide satisfactory immunogenic response and long-term efficacy in Chinese adults and that the persistence of immunogenicity is not related to the vaccine dose but to the candidate's own initial anti-HBs response.

Abstract
We measured the hemodynamic effects of intravenous vasopressin, ketanserin (a 5-hydroxytryptamine-2 receptor blocker), and vasopressin plus ketanserin in 33 patients with hepatitis B-related cirrhosis. Thirteen patients received vasopressin alone (0.66 units/min), ten patients ketanserin alone (10 mg), and ten patients vasopressin followed by vasopressin plus ketanserin. Vasopressin alone reduced the hepatic venous pressure gradient (from 18 +/- 5, mean +/- S.D., to 9 +/- 3 mmHg, p less than 0.0001) and cardiac output (p less than 0.0001), but increased mean arterial pressure (p less than 0.005), mean pulmonary arterial pressure (p less than 0.0001), pulmonary capillary wedge pressure (p less than 0.0001), and systemic vascular resistance (p less than 0.001). There was no significant change in heart rate. Ketanserin alone produced a significant fall in the hepatic venous pressure gradient (from 16 +/- 4 to 13 +/- 3 mmHg, p less than 0.0001), mean arterial pressure (p less than 0.005), mean pulmonary arterial pressure (p less than 0.005), and pulmonary capillary wedge pressure (p less than 0.005). Heart rate, cardiac output, and systemic vascular resistance were not significantly changed. The addition of ketanserin to vasopressin corrected most of the systemic hemodynamic disturbances produced by vasopressin. This combination did not lead to a further reduction in the hepatic venous pressure gradient. We conclude that intravenous ketanserin reduces portal pressure in patients with hepatitis B-related cirrhosis. The addition of ketanserin to vasopressin improves the detrimental systemic hemodynamic effects of vasopressin without further reducing the portal pressure.

Abstract
In a prospective study of 103 consecutive cirrhotic patients a high prevalence (43%) of anorectal varices was found compared with only 2% in 103 age- and sex-matched control subjects (p less than 0.001). However, there was no significant difference between the prevalences of hemorrhoids in cirrhotic patients and in control subjects (79% vs. 83%, p greater than 0.05). The hepatic venous pressure gradient of cirrhotic patients with anorectal varices was similar to cirrhotic patients without anorectal varices (14 +/- 6 mmHg, n = 22, vs. 16 +/- 7 mmHg, n = 39, p greater than 0.05. There was no significant difference in the hepatic venous pressure gradient between cirrhotic patients with and without hemorrhoids (15 +/- 6 mmHg, n = 47, vs. 16 +/- 8 mmHg, n = 14, p greater than 0.05). The prevalence of anorectal varices and hemorrhoids in cirrhotic patients had no relation to Child-Pugh's grading, esophageal varices with and without sclerotherapy and ascites. We conclude that anorectal varices are common in cirrhotic patients. Anorectal varices and hemorrhoids are not related to the degree of portal pressure.

Abstract
To assess whether the hepatitis C virus plays an important role in Chinese patients with acute and chronic liver disease, antibodies to HCV (anti-HCV) were measured by enzyme immunoassay in 67 patients with type A and B acute viral hepatitis, 165 patients with non-A, non-B (NANB) hepatitis, 438 patients with chronic hepatitis, 200 patients with postnecrotic liver cirrhosis, 72 patients with alcoholic liver disease, 55 patients with non-alcoholic fatty liver, 24 patients with toxic and drug-induced hepatitis, and 20 patients with other chronic liver diseases. Anti-HCV was not detected in sera from patients with type A and B acute viral hepatitis, toxic and drug-induced hepatitis, primary biliary cirrhosis, Wilson's disease, or lupoid hepatitis. The anti-HCV prevalence was found to be highest in patients with NANB hepatitis (59% in sporadic and 73.2% in transfusion-associated), 16.4% in non-alcoholic fatty liver, 5.6% in alcoholic liver disease, 6.8% in chronic hepatitis, and 16% in postnecrotic liver cirrhosis. In patients with chronic hepatitis, the anti-HCV prevalence was significantly higher in HBsAg-negative (15/34, 44.1%) than in HBsAg-positive cases (15/404, 3.7%; P less than 0.0001). The results indicate that HCV is a major agent of NANB hepatitis and plays an important role in HBsAg-negative chronic liver disease in Taiwan.

Abstract
To examine the relation between gastric ulcer (GU) location and serum pepsinogen I (PGI) level, we measured this marker in 284 endoscopically proved GU patients. Their ulcer locations were further divided according to Johnson's criteria modified to the corpus (type 1a), gastric angle (type 1b), combined with duodenal ulcer (type 2) and prepyloric area (type 3). The number of each subset were 96, 81, 58 and 49, respectively. Mean serum PGI level (99.6 +/- 44.8 ng/ml) of all GU patients showed no difference from that of their sex and age matched controls. Mean serum PGI levels in both type 1a and 1b patients, did not differ from each other but were significantly lower than in controls, in contrast to those in type 2 and 3 patients which were significantly higher than in controls and comparable to the PGI levels of patients with duodenal ulcer. Smoking did not affect mean serum PGI levels in all subsets except the smoking type 2 patients who manifested a significantly higher mean PGI level. Helicobacter pylori infection did not show different serum PGI levels in any subset. In conclusion, different location of ulcer in the stomach results in a characteristic serum PGI level.

Abstract
To delineate the natural clinical course of spontaneous bacterial peritonitis in hepatitis B-related cirrhosis and to determine if it occurs in hepatocellular carcinoma, a prospective survey was conducted in 262 patients over 2 1/2 years. The in-hospital incidence and mortality rates of spontaneous bacterial peritonitis were 21.6% and 36.4%, respectively, in cirrhosis and 7.3% and 50% in hepatocellular carcinoma. In cirrhosis, the cumulative probability of annual recurrence of spontaneous bacterial peritonitis was 47.3%, which was significantly higher than the annual probability of occurrence of 11.3% in those with no previous attack (P less than 0.0001). The cumulative probability of annual survival was 27.6% in the spontaneous bacterial peritonitis patients, significantly lower than the probability of 64.0% in the control group (P = 0.0001). A univariate analysis, with Kaplan-Meier curves compared by the Mantel-Cox test, and subsequent multivariate analysis by stepwise Cox regression procedure were used to evaluate 37 variables recorded immediately after admission. Blood urea nitrogen concentration greater than 10.5 mmol/L urea (greater than 30 mg/dL) and ascitic fluid protein concentration less than 7.35 g/L (less than 735 mg/dL) were found to be the only significant predictors of lower annual survival; ascitic fluid protein concentration less than 7.50 g/L (less than 750 mg/dL) was the only significant predictor of higher annual recurrence. The authors conclude that spontaneous bacterial peritonitis has a high risk of recurrence in hepatitis B-related cirrhosis and that the same disease occurring in patients with hepatocellular carcinoma is related to the underlying cirrhosis rather than the hepatocellular carcinoma.

Abstract
To investigate the gonadal dysfunction and changes in sex hormones in male patients with postnecrotic cirrhosis, and to compare them with those in alcoholic cirrhotic men, three age-matched groups of men (hepatitis B virus-related postnecrotic cirrhosis 27, alcoholic cirrhosis 21, normal controls 30) were studied. Twelve of the 21 (57%) alcoholic cirrhotics and 16 of the 27 (59%) postnecrotic cirrhotics had a history of impotence. Both alcoholic and postnecrotic cirrhotic patients had significantly lower basal testosterone, but higher estradiol and prolactin levels than the control group (p less than 0.05). However, no differences were noted between the two cirrhotic groups. The degree of reduced testosterone and increased prolactin levels correlated with the severity of the cirrhosis. Despite the low testosterone concentration, basal levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH) were not increased in the cirrhotic patients. All the three groups studied had normal FSH and LH responses to the stimulation of exogenous gonadotropin releasing hormone. On the basis of these results, we conclude that: (1) impotence and low testosterone level are not infrequent findings in men with hepatitis B virus-related postnecrotic cirrhosis, especially in those with decompensated liver function. (2) The liver disease per se is important for the development of male sexual dysfunction. (3) The derangement of hypothalamic-pituitary function may play a role in the sexual dysfunction and changes in sex hormones in male patients with cirrhosis.

Abstract
One hundred and eight primary school students who had been vaccinated with three doses of a plasma-derived hepatitis B vaccine were randomly divided into two groups, to receive a booster dose of either the same vaccine or of a recombinant yeast-derived vaccine. The pre-booster anti-hepatitis B surface antigen (HBs) geometric mean titres (GMT) were similar in both groups (281.8 mIU ml-1 versus 295.1 mIU ml-1, p greater than 0.5). One month after booster vaccination, all the vaccinees in both groups had a marked elevation in their anti-HBs titres, the anti-HBs GMT in group 1 and group 2 being 19,952.6 and 51,286.1 mIU ml-1 (p less than 0.05), respectively. In conclusion, the recombinant yeast-derived hepatitis B vaccine was able to elicit an excellent booster response in vaccinees who had originally received a plasma-derived vaccine.

Abstract
A randomized controlled trial was designed to investigate whether a high dose of terlipressin could control acute variceal haemorrhage more effectively than a low dose of terlipressin. Forty cirrhotic patients with bleeding oesophageal varices were included, with low-dose terlipressin in 21 patients and high-dose terlipressin in 19 patients. The two groups of patients were similarly matched for all parameters on admission. High-dose terlipressin (84%) seemed to be more effective in the initial control of bleeding than low-dose terlipressin (67%); however this difference was not significant. Complete control of bleeding during 24 h of drug infusion was achieved in 53% of patients receiving high-dose terlipressin and in 48% of those treated with low-dose terlipressin (P greater than 0.05). There were no major complications in either group. Mortality in relation to variceal bleeding and transfusion requirements were similar in the two groups. This study shows that high dose terlipressin is not superior to low dose terlipressin in acute variceal bleeding.

Abstract
Des-gamma-carboxy prothrombin (DCP) assay was performed by a staphylocoagulase method in 35 consecutive patients with small (less than 5 cm), resectable hepatocellular carcinoma (HCC). They also simultaneously received serum alpha-fetoprotein (AFP) assay. According to diagnostic strategy, patients were divided into two groups. Group I consisted of eight patients who were candidates for a mass screening project for HCC with elevated AFP levels (greater than 20 ng/ml). Five of these patients had an increased DCP level (greater than 6 U/l). Group II included 27 victims of chronic hepatitis B or cirrhosis whose tumors were detected by ultrasonography during regular follow-up. In this group, increased DCP and AFP levels were observed in 11 and 16 cases, respectively. Of 14 patients with smaller HCC (less than 3 cm), only three had elevated DCP levels, while eight patients had an abnormal AFP level. When these two assays were combined, 18 of 27 patients in group II and nine of 14 patients with smaller HCC (less than 3 cm) revealed elevation of one or both of the two markers. A total of 16 out of 35 patients with small HCC had abnormal DCP levels. In conclusion, DCP assay is less sensitive than AFP assay in the detection of small HCC, and the combination of both markers has little complementary effect.

Abstract
In an attempt to investigate the incidence and clinical course of type C viral hepatitis among patients with posttransfusion hepatitis, antibodies to hepatitis C virus (anti-HCV) in sera were measured from 42 prospectively followed cardiovascular surgery patients who developed hepatitis after blood transfusions. Of these, 35 (83.3%) had anti-HCV seroconversion during a 6- to 12-month follow-up period. The mean interval between blood transfusion and onset of active anti-HCV seroconversion was approximately 3 months after the first elevation of serum alanine aminotransferase levels (18.1 vs. 6.4 weeks). There was no correlation between fluctuations in serum alanine aminotransferase levels and anti-HCV titers. Of 26 patients with type C posttransfusion hepatitis who were followed greater than 1 year, 20 (76.9%) continued to have abnormal serum alanine aminotransferase levels. The results indicate that HCV is the major agent of posttransfusion hepatitis in Taiwan. Furthermore, it plays an important role in chronic hepatitis among transfused patients.

Abstract
To study the influence of hypoallergenic milk on the occurrence of allergic diseases, thirty-three high risk, normal full-term newborns were divided into two groups with comparable family allergy score (FAS) and cord serum IgE. Group A consisted of 18 babies fed since birth with regular formula, while group B included 15 babies fed breast milk and/or NAN H.A. (Hypoallergenic infant formula) for the first 6 months of life. Close clinical observations for the appearance of atopic dermatitis, allergic rhinitis and wheezing as well as serial examination of total serum IgE and milk-specific IgE antibodies were done during the first year of life. The results showed: 1) Infants fed regular formula had a higher incidence of moderate to severe atopic dermatitis (AD) and allergic rhinitis (AR) than those fed NAN H.A. (39% vs 13% for AD; and 33% vs 13% for AR), but the difference was not significant. There was no difference in the incidence of wheezing between these two groups; 2) There was no relationship between cord blood IgE and FAS; 3) Neither the cord blood IgE nor FAS influenced the occurrence of allergic diseases and total serum IgE at one year of age; 4) Hypoallergenic milk (NAN H.A.) could support normal growth and development. In conclusion, a higher incidence of moderate to severe AD and AR was found in high risk infants fed regular formula than in those fed hypoallergenic milk. However, a study with a larger number of babies and a longer period of follow-up is needed to obtain a solid conclusion.

Abstract
Ataxia-telangiectasia (A-T) is an autosomal recessive, multisystem disease characterized clinically by the onset of progressive cerebellar ataxia at about one year of age, followed by the development of fan-shaped telangiectasia of bulbar conjunctiva, usually at four- to six-years of age; and frequent sinopulmonary infections. The outstanding pathological findings in the central nervous system in A-T are loss of Purkinje cells and, to a lesser degree, basket and granular cells of the cerebellum. Although choreoathetosis and myoclonic jerks had been described in patients with A-T, torticollis has never been reported in the literature. A 7-year-old girl with A-T and torticollis is therefore presented in this paper.

The overall prevalence of antibody to hepatitis C virus was 0.28% among 1,419 healthy subjects, 0.8% among 500 unselected paid blood donors and 0.4% among 793 pregnant women. The three offspring of the mothers positive for antibody to hepatitis C virus were all found to be positive for antibody to hepatitis C virus at birth but all became negative by the age of 6 mo. Among healthy subjects, none of 1,000 school children and young adolescents had antibody to hepatitis C virus. Among patients in selected "high-risk" groups, antibody to hepatitis C virus was detected in 100% of 9 hemophiliac patients who were positive for antibody to human immunodeficiency virus, in 53% of 115 intravenous drug abusers, in 34.4% of 96 hemodialysis patient and in 15.8% of 19 homosexual men who were positive for antibody to human immunodeficiency virus. Only 7.1% of 196 prostitutes, 5.9% of 34 spouses of patients positive for antibody to hepatitis C virus and 0.5% of 201 brothelgoers had antibody to hepatitis C virus. These findings suggest that hepatitis C virus is transmitted mainly by the parenteral route in Taiwan. Transmission from mother to infant is not an important mode of spread of hepatitis C virus.

Abstract
Owing to the high false-negative rate of cytological examinations, various biochemical tests have been investigated to search for an alternative method to differentiate between the most frequent causes of ascites formation, i.e. cirrhosis of the liver and peritoneal carcinomatosis. For this purpose, serum and ascitic fluid samples of 71 ascitic patients (54 due to cirrhosis of the liver and 17 due to peritoneal carcinomatosis) were prospectively and simultaneously collected. Eleven major parameters were analyzed, and, of them, ascitic fluid protein, albumin, cholesterol, fibronectin and serum-ascitic gradient of protein and albumin were found to be useful. The serum-ascitic fluid albumin gradient was not as useful as described in the literature and, if clinically applied, the best cut-off value should be raised up to 1.5 gm/dl. Neither as useful was the serum-ascitic fluid protein gradient. Ascitic cholesterol and ascitic fibronectin were more accurate than the ascitic total protein, ascitic albumin and serum-ascitic gradient of protein and albumin in the diagnosis of peritoneal carcinomatosis. Of these tests, an ascitic fluid fibronectin concentration greater than 40 micrograms/ml was the most accurate parameter (diagnostic accuracy 96.2%) that could solely help to establish the diagnosis of peritoneal carcinomatosis.

Abstract
In an attempt to evaluate the effect of quinidine in the treatment of patients with cirrhosis and muscle cramps, 31 cirrhotic patients with muscle cramps were randomly divided into two groups and given orally 400 mg of quinidine sulfate per day or placebo, respectively. Baseline clinical and laboratory data for these two groups were similar. Four weeks after oral administration of quinidine, the number of cramps significantly decreased from 14.4 +/- 1.7 (mean +/- S.E.) to 4.4 +/- 1.1 episodes (p less than 0.0001), but it remained unchanged in the placebo group (from 11.8 +/- 1.0 to 11.5 +/- 1.5 episodes, p greater than 0.05). In addition, 88% of the 16 patients on quinidine and 13% of the 15 patients on a placebo showed a greater than 50% reduction in the number of cramps during a 4-week treatment period (p less than 0.0001). The peak and trough serum levels of quinidine in patients having received quinidine for 2 weeks were 1.3 +/- 0.1 and 0.7 +/- 0.1 mg/l, respectively. There was a significant relationship between serum quinidine concentrations and attenuation of cramps. No significant adverse effect was observed during the study, except for five (31%) patients who developed mild diarrhea after quinidine therapy. Diarrhea subsided spontaneously or was controlled by medications without the interruption of quinidine therapy. It was concluded that quinidine is a safe and effective drug for the treatment of cirrhotic patients with muscle cramps.

Abstract
It has been suggested that vasopressin given during hemorrhage may be less effective than when given during a stable state in a portal-hypertensive rat model. This study was designed to evaluate the hemodynamic response to vasopressin infusion in 25 HBsAg-positive cirrhotic patients. Nine patients had active variceal hemorrhage before vasopressin infusion, and the other 16 patients were in a stable condition at the time of infusion. The two groups of patients were similar in baseline values except that a higher heart rate was found in patients with hemorrhage (96 +/- 20 vs. 73 +/- 10 beats/min, mean +/- S.D., p less than 0.01). Thirty minutes after vasopressin infusion (0.66 units/min), hepatic venous pressure gradient significantly decreased in both bleeding and stable patients (from 21 +/- 9 to 18 +/- 9 mm Hg, p less than 0.05; and from 18 +/- 4 to 8 +/- 3 mm Hg, p less than 0.0001, respectively). However, the decrease of hepatic venous pressure gradient was less obvious in bleeding patients as compared with stable patients (4 +/- 3 vs. 9 +/- 2 mm Hg, p less than 0.0001). A significant reduction of hepatic venous pressure gradient after vasopressin infusion was found in five bleeding patients without shock (from a median of 16 mm Hg [range = 12 to 26] to 11 mm Hg [range = 6 to 18], p less than 0.05), but not in four bleeding patients with shock (from 28 [range = 15 to 36] to 25 [range = 18 to 33] mm Hg, p greater than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We performed endoscopic injection sclerotherapy (EIS) in the treatment of 37 patients with bleeding esophageal varices due to unresectable hepatocellular carcinoma (HCC). The results were compared with those in another 33 HCC patients treated only conservatively, without EIS, during the same period. A majority of both groups died within 3 weeks after treatment. Comparing the two groups, there was no significant difference in fatal bleeding (66% vs 75%), but significantly fewer of the EIS patients died of the index hemorrhage (43% vs. 83%; p less than 0.01). Also, in the absence of portal vein thrombosis, EIS significantly reduced the risk of fatal bleeding (31% vs. 73%; p less than 0.25). The mean days of survival were 32 +/- 15 (range, 2 to 320) in the EIS group and 10 +/- 14 (range, 2 to 270) in the compared group (p less than 0.001). We conclude that EIS provides temporary control of acute esophageal variceal bleeding in patients with unresectable HCC. The major factors contributing to EIS failure are the lethal propensity of the underlying disease and portal vein thrombosis.

Abstract
In an attempt to investigate the incidence and clinical course of non-A, non-B (NANB) hepatitis following blood transfusion in Taiwan, 288 patients who underwent cardiovascular surgery and received blood transfusion were followed prospectively with serum liver aminotransferase levels and viral hepatitis markers for at least six months. None had any past history of liver disease or drug abuse. All blood donors were tested for serum hepatitis B surface antigen and alanine aminotransferase (ALT) (greater than 45 U/L). Thirty-seven (12.8%) patients developed PTH. 34 (91.9%) were considered to be cases of NANB hepatitis, 2 (5.4%) were cytomegalovirus hepatitis, and one (2.7%) was caused by Epstein-Barr virus. No one developed hepatitis B post-transfusion hepatitis (PTH). Of the 34 NANB PTH patients, 15 (44.1%) were asymptomatic, 16 (47.1%) had clinical symptoms, and 9 (26.5%) had serum total bilirubin levels higher than 2 mg/dl. There was no case of fulminant hepatic failure. Of 26 NANB PTH patients who were followed up for more than one year, 15 (57.7%) still had abnormal serum ALT levels. The incubation period of NANB PTH ranged from 2 to 16 (mean 6.1 +/- 3.2) weeks. Of the 37 PTH patients, 32 (86.5%) were found to have anti-HCV seroconversion during one year follow-up period. NANB PTH is as common in Taiwan as in the United States and Japan, and is demonstrated by this study to be due mostly to HCV.

Abstract
Gastric mucosal lesions are common in patients with cirrhosis. Among them, snake skin pattern gastropathy (SSPG) is the most distinguishing one. A prospective study was conducted to investigate the incidence of SSPG in cirrhotic patients, the relationship between the degree of portal pressure and SSPG, and the possible association of SSPG with serum levels of gastrin and pepsinogen I. SSPG was found to be significantly more common in 100 cirrhotic patients than in 100 age- and sex-matched healthy controls (41% vs 0%, P less than 0.0001). Hepatic venous pressure gradient and serum gastrin and pepsinogen I levels were measured in 21 cirrhotic patients with SSPG and 25 cirrhotics without SSPG. There was no significant difference in hepatic venous pressure gradient (16.1 +/- 4.4 mmHg vs 16.1 +/- 4.9 mmHg, P greater than 0.05), serum gastrin level (78.0 +/- 26.7 pg/mL vs 80.1 +/- 32.5 pg/mL, P greater than 0.05) and serum pepsinogen I level (69.5 +/- 26.6 ng/mL vs 65.2 +/- 26.1 ng/mL, P greater than 0.05) in cirrhotic patients with or without SSPG. In conclusion, SSPG is common in cirrhotic patients. Portal pressure per se may not be the only factor causing SSPG--other aggressive factors may be needed together to cause the gastropathy. There is no evidence of correlation between serum gastrin or pepsinogen I level and SSPG.

Abstract
Forty-one hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA positive Chinese patients with chronic active hepatitis B were randomized to receive either prednisolone or placebo oral for 8 weeks. The prednisolone group received 60 mg daily for 2 weeks, 40 mg for 2 weeks, 20 mg for 2 weeks, 10 mg for 1 week and 5 mg for 1 week. In 18 patients receiving prednisolone, serum HBV DNA levels rose during the course of therapy, but dropped abruptly within 1 month of cessation of treatment. Conversely, their serum alanine aminotransferase (ALT) levels decreased during high doses of prednisolone therapy, and then became transiently elevated during the period of withdrawal of prednisolone. At 1 year from initial treatment, the serum HBV DNA and ALT levels were similar between the groups of patients treated with prednisolone or placebo. In the prednisolone treated group, 66.7% of patients became HBV DNA negative, 50% became HBeAg negative, and 33.3% seroconverted to antibody to HBeAg (anti-HBe). In the placebo treated group, 60.9% of patients became HBV DNA negative, 60.9% became HBeAg negative, and 56.5% seroconverted to anti-HBe. Hepatic decompensation was not noted in any of the prednisolone-treated patients. Thus, the effects of the withdrawal prednisolone therapy on serum ALT and HBV DNA levels was temporary, and no differences in serum viral markers or biochemical parameters of liver inflammation between these two groups were noted at the 1 year follow-up period.

Abstract
A panel of tests including intracutaneous skin testing (ST), radioallergosorbent test (RAST), immunoblotting and allergen-induced lymphoproliferation was done to study rice pollen allergy in asthmatic children and to characterize the allergens. Of the 312 asthmatic patients skin tested, 29 (9.3%) had positive reactions (wheal greater than or equal to 6 mm) to rice pollen extract at a concentration of 10(-5) g/mL and the remaining 283 (90.7%) were negative. While eight (34.8%) of the 23 ST-positive patients were also RAST-positive, RAST was negative in all 34 ST-negative patients and 20 normals. Immunoblotting revealed three major allergens, with molecular weights of 16 kD, 26 kD, and 32 kD, respectively. Interestingly, RAST-positive patients showed IgE responses to most allergens but only a few of them had IgG antibodies, while normal controls had stronger IgG responses to the same allergens, particularly to 32 kD, but none had IgE antibody. The preliminary results of rice pollen protein induced-lymphoproliferation were not informative; thus, rice pollen proteins do elicit a specific response in asthmatic children and normals, but its pathogenic role in bronchial asthma needs further study.

Abstract
Among 30 consecutive patients diagnosed with primary biliary cirrhosis (PBC) in Taiwan, 27 were females and the median age of symptom onset was 54.5 years. Most had similar clinical manifestations to those reported in the Western countries, but ascites and oesophageal varices as commonly found at the late stages of cirrhosis of liver were noted in nine patients (30%) and 13 patients (43%) respectively. Only one patient was asymptomatic. Hyperbilirubinaemia was noted in 21 patients (70%) and hypoalbuminaemia in 8 patients (27%). All patients had elevated serum alkaline phosphatase and alanine aminotransferase and 28 (93%) had antimitochondrial antibodies. Ten out of 21 patients (48%) were positive in antinuclear antibodies, of which most were of speckled type. Sixteen out of 18 patients (89%) had elevated serum IgM levels. Interestingly, only one of 26 patients (3.8%) was positive for hepatitis B surface antigen, in contrast to its high prevalence (15%) in the Taiwan population. Special associated diseases, including systemic lupus erythematosus, scleroderma, malignant lymphoma and hepatocellular carcinoma, were each noted in one patient respectively. Eight patients had a history of gallstones before the diagnosis of PBC. The mean follow-up period was 23.6 +/- 19.8 months, and nine patients died during that period. In conclusion, the clinical manifestations of PBC in Taiwan are similar to those in Western countries, but most of our cases were at later stages.

Abstract
In a period of 2 years 7 months, we performed heat probe (HP) thermocoagulation in 153 cases of massive peptic ulcer hemorrhage. The male/female sex ratio was 125/28. The average age was 57.6 +/- 1.3 years (mean +/- SEM; range, 17 to 88). There were 69 cases (45.1%) of spurting hemorrhage, 50 cases (32.7%) of oozing hemorrhage, and 34 cases (22.2%) of nonbleeding visible vessels. Seventy-seven patients (50.3%) were in shock before therapy. After therapy we obtained initial success in 147 cases (96.1%). Rebleeding episodes occurred in 23 patients (15.6%) within 1 month after therapy. Nineteen patients received a second therapy, and treatment in 15 of these cases (78.9%) was ultimately successful. Finally, treatment in 142 cases (92.8%) was ultimately successful. The duration of hospitalization was 6.3 +/- 0.4 days (mean +/- SEM). After discharge all patients were followed at the outpatient department for at least 1 month. Sixty-seven patients were followed endoscopically for at least 2 to 3 months after therapy. Fifty-six patients (83.6%) had a healed scar at the previous bleeding site 2 months after therapy, and 62 patients (92.5%) had a healed scar 3 months after therapy. We conclude that HP thermocoagulation is an ideal and reliable modality of therapeutic endoscopy in arrest of massive peptic ulcer hemorrhage. HP thermocoagulation may become the first choice of therapy for massive peptic ulcer bleeding in the near future.

Abstract
We conducted a prospective randomised controlled trial of 137 patients with massive peptic ulcer haemorrhage over a period of 12 months to compare the haemostatic effects of endoscopic heat probe thermocoagulation and pure alcohol injection. Seventy eight patients (56.9%) were in shock at the time of randomisation to the trial. The age, sex, number of patients in shock, haemoglobin value at the time of entry to the trial, number of patients with severe medical illness, location of bleeders, and stigmata of recent haemorrhage were comparable among the heat probe, pure alcohol, and control groups. The initial haemostatic effect of the heat probe was better than that of the pure alcohol injection (44 of 45 v 31 of 46, p = 0.0004). The ultimate haemostasis achieved by the heat probe group (41 of 45) was better than that of the pure alcohol group (31 of 46, p = 0.012) and of controls (24 of 46, p = 0.0001). The duration of hospital stay was shorter for patients in the heat probe group than for the control group (6.2 days v 13.8 days, p less than 0.05). The incidence of emergency surgery was less for the heat probe than the control group (three of 45 v 12 of 46, p = 0.027). The mortality rate was less in the heat probe than in the control group (one of 45 v seven of 46, p = 0.031). We suggest that heat probe thermocoagulation should be the first treatment of choice for arrest of massive peptic ulcer haemorrhage.

Abstract
Multivariate analysis of the risk factors for hepatitis D virus infection among 53 men with acute hepatitis D virus superinfection, 59 men with acute exacerbation of chronic hepatitis B and 54 asymptomatic male hepatitis B carriers revealed that sexual contact with prostitutes and use of nondisposable needles were the factors significantly associated with hepatitis D virus infection in Taiwan (odds ratio = 5.5, 95% confidence interval = 3.3 to 9.2; odds ratio = 2.4, 95% confidence interval = 1.3 to 4.4, respectively). The prevalence of antibody to hepatitis D virus antigen among hepatitis B virus carriers with histories of sexual exposure to prostitutes was 10.3% (14 of 136) and the prevalence of hepatitis D virus antigen among the female prostitutes who were hepatitis B virus carriers was 59% (24 of 51). Among those who admitted to sexual contact with prostitutes, testing for hepatitis D virus antigen revealed positive correlations with the frequency of such sexual contacts and with the frequency of history of venereal diseases. Among the female prostitutes, the prevalence of hepatitis D virus antigen had a positive correlation with the frequency of sexual contact and a negative correlation with age. Analysis of serum hepatitis D virus RNA among those with hepatitis D virus antigen revealed that 4 of the 9 with sexual exposure to prostitutes and 3 of the 24 prostitutes were positive. From these findings, we conclude that these two groups are not only at high risk for hepatitis D virus infection but also form a reservoir of this virus.

Abstract
Twenty of 22 hepatitis delta virus (HDV)-superinfected chronic hepatitis B carriers who had detectable HDV RNA at the acute stage progressed to chronicity, while only 6 of 16 patients without HDV RNA did so (P less than .005). The poor outcome of patients with persistently positive or fluctuating HDV RNA has been indicated by the following findings: 24 of 38 patients suffered from prolonged hepatic inflammation complicated by three to eight episodes of exacerbations; among them, 5 developed cirrhosis and 2 died in a follow-up period of 4 years. For most patients, the replication of HBV was suppressed at acute stage; only 3 of the 38 cases had detectable HBV DNA in sera. While reactivation of HBV was found in another 8 patients in the follow-up period, for 5 it was in the presence of serum HDV RNA and 2 developed cirrhosis. Therefore, serial assays of serum HDV RNA and HBV DNA appeared to be of value in monitoring the clinical course and outcome of acute HDV superinfection and in the study of the long-term interactions between these two viruses.

Abstract
In a period of 14 months, a prospective, randomized, controlled trial was undertaken in 61 patients who had bled from peptic ulcers in which, at endoscopy, non-bleeding vessels were visible in the ulcer crater. The control group consisted of 31 patients in whom the procedure was limited to observation alone; in 30 patients the ulcer base was coagulated by means of a heat probe. There were no statistically significant differences between the two groups in the rate of rebleeding, the assurance of ultimate hemostasis, the volume of blood transfusion required, the duration of hospitalization, or eventual mortality. However, the need for emergency surgical intervention was less frequent in the heat probe group (2 of 30) than among the controls (9 of 31) (p = 0.0243). Moreover, in the treatment group, those patients of advanced age (greater than 60 years), in shock, requiring blood transfusion of greater than 500 ml, and in whom blood or coffee ground material was seen in the stomach, thermocoagulation achieved statistically more effective hemostasis than that observed in the control group. For these high-risk subsets of patients with non-bleeding visible vessels, we recommend heat probe coagulation rather than mere observation.

Abstract
We measured the haemodynamic changes following triglycyllysine vasopressin administration and after addition of nitroglycerin in twelve patients with portal hypertension due to hepatitis B-related cirrhosis. A bolus i.v. injection of triglycyllysine vasopressin at a dose of 2 mg reduced the hepatic venous pressure gradient from 18.5 +/- 3.7 (mean +/- S.D.) to 15.6 +/- 4.0 mmHg, p less than 0.001. However, the cardiac index decreased from 4.8 +/- 1.0 to 3.7 +/- 0.8 l/min m2, p less than 0.001; the heart rate decreased from 79 +/- 15 to 71 +/- 13, p less than 0.01; the right atrial pressure increased from 3.2 +/- 1.9 to 5.3 +/- 2.3 mmHg, p less than 0.001; the mean arterial pressure increased from 92 +/- 13 to 103 +/- 13 mmHg, p less than 0.05; and the systemic vascular resistance rose from 939 +/- 182 to 1367 +/- 310 dyn/s cm-5, p less than 0.001. Furthermore, both mean pulmonary arterial pressure and pulmonary capillary wedge pressure showed a significant increase following triglycyllysine vasopressin administration as compared with baseline values (p less than 0.005). The addition of sublingual nitroglycerin at a dose of 0.6 mg returned all the systemic haemodynamic parameters to baseline levels. On the other hand, nitroglycerin administration caused no further change in the hepatic venous pressure gradient. We concluded that although triglycyllysine vasopressin significantly reduced portal pressure in patients with hepatitis B-related cirrhosis, it produced untoward systemic haemodynamic changes similar to those seen with vasopressin. The addition of nitroglycerin improved the detrimental systemic haemodynamic effects produced by triglycyllysine vasopressin without further reducing the hepatic venous pressure gradient.

Abstract
In order to understand whether the serum pepsinogen I (PGI) levels of non-ulcer dyspepsia (NUD) patients differed from those of healthy controls and which kinds of factors might influence these levels of the former, serum PGI levels were determined by radio-immunoassay in 120 healthy controls and 361 NUD patients. The mean serum PGI level was significantly lower in NUD patients than in the controls (75.8 +/- 38.2 ng/mL versus 95.9 +/- 39.3 ng/mL; P less than 0.0001); in NUD patients, it was significantly higher in males than in females (79.6 +/- 40.4 ng/mL versus 63.2 +/- 26.4 ng/mL; P less than 0.001). However, corrected serum PGI levels according to the lean body mass disclosed no sex difference. Nevertheless, there was a weak correlation between the ages of patients and serum PGI levels (r = 0.403). The serum PGI levels in blood groups A, B, AB and O did not differ significantly. Smoking might be a decisive factor, for the mean serum PGI level was significantly higher among the smokers than among the non-smokers (86.7 +/- 44.6 ng/mL versus 70.6 +/- 33.7 ng/mL; P less than 0.001). It is concluded that the mean serum PGI level of NUD patients, while affected by sex, age, smoker status and the body size, is lower than that of the healthy controls. Without endoscopy, assay of serum PGI level has no place in the diagnosis of dyspepsia because of the wide overlapping of serum PGI levels between NUD patients and patients with other common gastric lesions.

Abstract
To elucidate the effects of verapamil on splanchnic haemodynamics in rats with portal hypertension, verapamil was given at a low dose (0.2 mg/kg) and a high dose (2 mg/kg) to the rat model after portal vein ligation. Approximately 10% decrease in arterial pressure was caused by the low dose of verapamil, with significant decreases in cardiac output and portal venous inflow as well as reduced portal pressure; these were all indicative of a rise in portal vascular resistance. In contrast, the marked fall in both arterial pressure and cardiac output in the high dose, accompanied by a significant decrease in the portal pressure and the unchanged portal venous inflow, suggested a reduction in portal vascular resistance. This study shows that the acute effects of verapamil on portal hypertension may vary with the dosage used. These results also demonstrate that, since the therapeutic efficacy and safety of verapamil is only in a very limited range of dose, caution should be taken in its clinical use in the treatment of cirrhosis with portal hypertension.

Abstract
Conflicting results have been common in the pharmacological treatments of portal hypertension. In an attempt to seek better management of portal hypertension, we studied the effect of the synthetic parathyroid hormone (PTH) fragment, [bPTH-(1-34)], in portal hypertensive rats (partial portal vein ligation). PTH, 10 U/kg, administered via the jugular vein resulted in a reduction of both mean arterial blood pressure (MAP) and portal pressure (PP) to a similar extent (18.9% and 16.9%, respectively). A higher dose (40 U/kg) of PTH lowered the PP by 27.8% and MAP by 43.2%. Hemodynamic experiments, performed with labelled microspheres, demonstrated that PTH decreased the blood flow of the splanchnic and hepatic portal collateral vascular beds. To determine whether there is a direct vasodilatory effect on the venous vasculature, the effect of PTH on the isolated portal vein was examined. PTH was capable of inhibiting both spontaneous and drug (methacholine 10(-7) mol/l or KCl 40 mmol/l-induced contraction in a dose-dependent manner. Therefore, it can be assumed that some of the effect of PTH on portal pressure is due to a selective effect on the portal vein.
