Abstract
The presence and inducibility of the major cadmium (Cd) chelating protein metallothionein (MT) in testicular cells has been controversial. In this study, the induction and production of MT in testicular cells were studied using mouse Leydig and Sertoli cell lines. Metal accumulation was studied by subjecting the cells to increasing levels of Cd. The presence of transcription factors for MT synthesis was analyzed by transfecting the cells with a reporter gene under the control of the MT promoter. The dose- and time-dependent induction of MT were conducted by Northern analyses. Expression of MT genes occurred in both Leydig and Sertoli cells. To avoid cross hybridization of the MT probe with mRNAs encoding testicular metal binding proteins and to investigate the integrity of MT mRNA, isoMT mRNA identification and primer extension experiments were performed. Those studies show that the induced mRNA indeed encodes MT. The biosynthesis of MT was confirmed by following 35S-cysteine incorporation into the protein. Finally, cadmium tolerance of testicular cells is compared with that of fibroblast cells. By these studies, we conclude that the MT genes are functional and inducible in testicular cells.

Abstract
A 24-year-old man presented with vague abdominal fullness and a mild epigastric dull pain for about 3 months was found to have a pancreatic head tumor at a medical center 2 months ago. He came to our hospital for further treatment. Ultrasonography, endoscopic retrograde cholangiopancreatography (ERCP) and abdominal computed tomography (CT) all revealede a pancreatic head tumor. Laparotomy was performed because pancreatic head carcinoma was highly suspected. Indurated mass in the pancreatic head, enlarged lymph nodes and white tubercles on the intestine proved to be tuberculosis on histological examination of a frozen section. Acid fast bacilli were also found. The patient was given antituberculous therapy and is now doing well. To avoid unnecessary laparotomy, CT, echo-guided percutaneous aspiration cytology or biopsy and culture of the tissue for mycobacteria should be done in a patient with pancreatic mass, especially in a region where pulmonary and abdominal tuberculosis are common.

Abstract
OBJECTIVE To assess the efficacy, safety, and acceptability of NORPLANT implants when used by Chinese women. METHODS In a prospective, multicenter clinical trial, 10,718 women selecting NORPLANT implants were monitored semiannually for the first 2 study years and then annually through 5 years. Life table rates of pregnancy and other terminations were calculated, as were incidence rates of serious conditions leading to termination. RESULTS The 5-year average annual pregnancy rate was 0.3 per 100 and the ectopic pregnancy rate was minimal, 0.09 per 1000 woman-years. Pregnancy rates correlated significantly with weight, but regardless of weight group, annual average pregnancy rates were less than one per 100. Younger women experienced higher pregnancy rates than did older users. Headache, myoma, dizziness, and weight gain led more frequently to termination than did other adverse events apart from menstrual disturbances. Mortality during use was 2.0 per 10,000 years, based on 44,954 years of experience. There were no cardiovascular or cerebrovascular deaths, and no deaths were attributable to NORPLANT use. Seventy-two per 100 initial acceptors used the implants continuously for 5 years. CONCLUSION NORPLANT implants proved highly effective, safe, and acceptable among Chinese women regardless of province, age, or weight at admission.

Abstract
Conjugation in the fission yeast Schizosaccharomyces pombe is controlled by the reciprocal action of mating pheromones. We recently showed that M-factor, the pheromone released by cells of the cellular mating type Minus, is a nonapeptide in which the C-terminal cysteine residue is carboxyl-methylated and S-alkylated, probably with a farnesyl residue (Davey, 1992): Tyr-Thr-Pro-Lys-Val-Pro-Tyr-Met-Cys(S-farnesyl)- OCH3. Here we describe the chemical synthesis of this modified peptide and show that it exhibits all of the properties of the native pheromone. These results confirm the structure of the M-factor while the production of relatively large amounts of pure pheromone will be invaluable for studying the mating response in this yeast.

Abstract
Cysteine-containing amino acid sequences (CAAX, CC, and CXC; C is cysteine, A is any aliphatic amino acid, and X is any amino acid) are targets for the attachment of C15 (farnesyl) and C20 (geranylgeranyl) isoprenoids to peptides and proteins by specific prenyltransferases. Although much work has centered on the enzymatic mechanisms of these enzymes, the biological consequences of the differential isoprenylation they catalyze remain to be elucidated. Farnesylation of the a-factor mating pheromone of Saccharomyces cerevisiae is a known prerequisite for its biological activity and its secretion through a pathway utilizing the yeast STE6 protein, a homolog of the mammalian multidrug resistance (MDR) P-glycoprotein. We generated specific mutations in the a-factor gene to encode isoprenylation targets for geranylgeranylation [Cys-Val-Ile-Leu (CVIL) and Ser-Val-Cys-Cys (SVCC)] in place of the natural farnesylation motif [Cys-Val-Ile-Ala (CVIA)]. The a-factors containing these modified prenylation sites were successfully exported by a STE6-dependent mechanism. Furthermore, these peptides, as well as synthetic geranylgeranyl a-factor, retained bioactivity. Chromatographic comparisons of synthetic and biosynthetic pheromones suggest that, in vivo, a peptide substrate containing the geranylgeranylation target CVIL can be both farnesylated and geranylgeranylated. These results clearly demonstrate that in vivo (i) different prenyltransferases may recognize the same substrate; (ii) both farnesylated and geranylgeranylated a-factor peptides are substrates for export via STE6, a MDR-like protein; and (iii) farnesylated and geranylgeranylated pheromones are both biologically active.

Abstract
If a peripheral nerve could be elongated by a tissue expander (TE) without apparent damage, the length gained could be used to overcome a nerve gap without recourse to nerve graft. An experimental study was made to investigate whether this method for repairing a nerve gap is feasible. The tissue expander was designed by the authors and the median nerve of rabbits were stretched with TE at the rate of about 1 mm/day. The results showed that when the elongation rate was 18.4%, the motor nerve conduction velocity (MCV) was 67.8% and the myelinated nerve fibres (MNF) was 82.9% of the control nerves. In a further study nerve grafting and nerve expansion for repairing segmental nerve loss were compared with 10 mm defects. 4 months later the MCV, MNF, isometric contraction force (ICF) and muscle wet weight (MWW) were not significantly different between the 2 techniques. But with the 15 mm defects, elongated nerve were inferior to the nerve grafting method.

Abstract
On the basis of the international evaluation of impairment of hand function, we propose five improvements: (1) For the evaluation of the impairment of thumb opposition and adduction, calculating the ratio of two distances takes the place of measuring a pure distance. (2) Hand sensory impairment evaluation is based upon both results of a sensory examination and a two-point discrimination test. (3) On the evaluation of amputation percentages related to whole hand, measuring loss of length is replaced by measuring loss of area. (4) On the evaluation of a joint, we correlated the combined angular measurement with the loss of length. (5) In the international evaluation of impairment of hand function, the sensory or amputation of the palm and back of the hand is not counted. But they are counted in our paper. Besides above-mentioned works, we have made a software with these improvements. You may obtain definite impairment percentages related to whole hand, so long as you input the results of examination of hand function.

Abstract
The yeast mating pheromone a-factor is a farnesylated peptide [YIIKGVFWDPAC(Farnesyl)-OCH3] involved in the signal transduction cascade which leads to sexual conjugation of haploid cells. We have identified a synthetic analog of the a-factor, [D-Ala5] a-factor, which exhibits 4-6 fold greater biological activity than that of a-factor as judged by two different assay systems. In contrast, [L-Ala5] a-factor has 4-16 fold lower activity than wild-type a-factor. [D-Ala5] a-factor remains susceptible to cleavage by the yeast alpha-cell specific protease a-factorase, thereby ruling out increased activity due to greater stability. This report describes the first example of a hyperactive S. cerevisiae pheromone and may suggest a conformationally preferred form of this lipopeptide ligand.

Abstract
We have studied the interaction between phospholipids and a-factor (YIIKGVFWDPAC-[Farn]OMe), S-alkylated forms of a-factor with the farnesyl group substituted by methyl, hexadecanyl, or benzyl groups, and truncated forms of this lipopeptide. Circular dichroism studies suggest that, despite its lack of farnesylation, S-methyl-a-factor is incorporated into vesicles of dimyristoylphosphatidylcholine in a conformation similar to that which a-factor adopts in this membrane. However, studies of the intrinsic fluorescence of the Trp residues of these peptides indicate that this residue is more deeply imbedded into the bilayer in the case of the farnesylated peptide. The a-factor is more effective in raising the bilayer to the hexagonal phase transition temperature of dielaidoylphosphatidylethanolamine than is the S-methyl-a-factor. This bilayer-stabilizing ability is also reflected in a-factor inhibiting leakage from vesicles of N-methyldioleoylphosphatidylethanolamine. Studies on a-factor analogs permit the conclusion that the bilayer-stabilizing effect of a-factor is not solely a consequence of its greater partitioning into the membrane but is also a consequence of the degree of penetration into the bilayer and the specific conformation of the peptide at the membrane interface. These results indicate that the farnesyl group alone, in the absence of cellular factors, bestows a particular physical interaction with membranes.

Abstract
By means of cell culture, 3H-thymidine (3H-TdR) incorporation and c-fos oncogene dot plotting technique, it was found that endothelin (ET) and angiotensin (ANG II) could promote proliferation and DNA synthesis of cultured vascular smooth muscle cells (VSMCs) and myocardial cells, and stimulate expression of c-fos oncogene of VSMCs. However, atrial natriuretic peptide (ANP) antagonizes the above effects of ET and ANG II.

Abstract
Previous studies suggest that myopia in parents may influence the genesis of myopia in their offspring. In this study, we surveyed 2888 children of Chinese descent in China and Hong Kong to determine the relationship between the refractive state of parents and their children. The age range of the children was 7-17 years. Refraction was measured using a Canon R-22 objective infrared autorefractor and a survey on family history of ametropia was conducted using a questionnaire. We found that children with myopic parents are more likely to be myopic.

Abstract
The effects of cocaine on the contractile response of isolated human nasal mucosal blood vessels to field stimulation and methoxamine were investigated. Results showed that cocaine antagonized methoxamine and inhibited field stimulation. The drug increased resting tension in human nasal mucosa in vitro through direct actions and potentiated mucosal contractions by norepinephrine and epinephrine. The study indicated that high concentrations of cocaine may actually antagonize alpha-adrenoceptors, but these concentrations are not necessary in eliciting desired degrees of vasoconstriction in nasal blood vessels while being applied as a local anesthetic.

Abstract
Doppler ultrasonic monitoring was used to detect bubbles in sixteen guinea pigs subjected to a simulated air-dive profile of 9 ATA for 25 minutes. After completion of the decompression, eight subjects did not demonstrate any signs of decompression sickness (DCS), two developed paraplegia and six died. Under sedation, the Doppler ultrasonic bubble detector was placed precordially to record the bubble signals in both pre-dive and post-dive. The recorded signals were analyzed with a high resolution signal analyzer to compare changes between pre-dive and post-dive spectrograms. Bubble signals appeared in the frequency range between 0.64 +/- 0.02 KHz and 6.08 +/- 0.30 KHz. In terms of the net spectral level versus frequency areas (difference between pre-dive and post-dive spectrograms), the mean areas in the paraplegia group and the death group were significantly larger than those in the group without DCS. Therefore, we concluded that the spectral analysis may be an objective and quantitative adjunctive method to the interpretation of Doppler bubble signals.

Abstract
Rabbits were fed on cholesterol-rich (CHO) diet first for 60 days, and serum cholesterol, serum lipid peroxides (LPO) and superoxide dismutase (SOD) activities were measured at various periods after the withdrawal of the CHO-rich diet. The correlation of the above figures and the initiation, progression and regression of atherosclerotic lesion were studied. Results showed that: (1) when rabbits were fed on a CHO-rich diet for 60 days, the serum CHO and LPO increased significantly. Anyhow, the SOD activity was only slightly elevated when tiny atherosclerotic lesions developed in the aortae. (2) right after withdrawal of the CHO diet, serum CHO decreased significantly, but atherosclerotic lesion became even more severe than before. (3) after withdrawal of the CHO diet for 120 days, serum CHO, LPO content and SOD activity all returned to normal range and the atheromatous lesion became less severe except calcification and fibrosis developed in certain areas.

Abstract
We observed the effects of intravesical irrigation with BCG (group B), Mitomycin-C (group M), and Thiotepa (group T) in prophylaxis of bladder tumor recurrence after surgical treatment. Follow-up for 1-10 years showed that the recurrence rate of bladder tumor was 12.5% (3/24) in group B, 46.9% (15/33) in group M, and 61.8% (21/34) in group T respectively. The effect of BCG was far better than that Mitomycin-C and Thiotepa (P < 0.01). In 5 cases, who failed to Thiotepa, also showed satisfactory results after use of intravesical BCG. Considering the side-effects of intravesical BCG, Thiotepa or Mitomycin-C should be used as the first choice of drugs in preventing the tumor recurrence.

Abstract
We compared the effect of a single dose of ivermectin with that of a standard course of diethylcarbamazine (DEC) on several parameters of the host's antifilarial immune response in 60 patients with bancroftian filariasis enrolled in a double-blind drug trial. All participants had measurable serum levels of antifilarial antibodies and parasite antigens at the onset of the study. Drug-induced clearance of microfilaremia was associated with a temporary increase in HC 11 antigenemia and a decrease in serum levels of antibodies to soluble filarial antigens. Antigenemia progressively declined in patients who remained amicrofilaremic after treatment, but declined and then increased in persons with recurrent microfilaremia. Treatment triggered a sustained increase in serum levels of interleukin-1, tumor necrosis factor, and interleukin-6 in all patients studied. Although ivermectin and DEC are believed to exert their antiparasite activity via different mechanisms, the same pattern of serologic changes was observed in patients treated with either drug.

Abstract
We compared the efficacy of a single dose of ivermectin with that of a standard course of diethylcarbamazine (DEC) for the control of microfilaremia in 60 patients with bancroftian filariasis who had developed recurrent microfilaremia after each of three or more prior treatments with DEC. The study was done as a randomized, double-blind trial. Complete, but in some cases, transient clearance of microfilaremia was observed in both treatment groups. At one year, recurrent microfilaremia was present in seven patients treated with ivermectin and in five treated with DEC. Pretreatment levels of microfilaremia were significantly higher in patients who relapsed within one year after treatment than in those who remained amicrofilaremic. Side effects with both treatments were common, but mild. Febrile reactions were more frequent in the ivermectin group; localized reactions consistent with a flare-up of acute filarial disease occurred mostly in the DEC group. We conclude that ivermectin is an effective and practical alternative to DEC for treatment of recurrent microfilaremia due to bancroftian filariasis.

Abstract
Anti-DNAse B test was performed with microtechnique in 160 subjects including patients with acute streptococcal pharyngitis, rheumatic fever and rheumatic heart disease as well as normal controls. It was shown that the antibody titer varied with age, stage of rheumatic fever and rheumatic heart disease as well as the frequency of benthazine penicillin injections. It was also shown in this study that the school children group had considerably higher geometric mean antibody titer than the adult group. The upper normal limit of anti-DNAse B titer was 240 units in the school children group and 160 units in the adult group. The anti-DNAse B test shows a higher positive detection rate for streptococcal infection than ASO, especially when these two tests are used in combination. In patients with manifestations of acute rheumatic fever without elevation of ASO titer, anti-DNAse B test will be of great diagnostic value.

RPMI-1640 tissue culture medium containing 6% dimethyl sulfoxide (DMSO) and 15% newborn calf serum was used as cryoprotectant. Samples were frozen slowly in the vapor phase of liquid nitrogen prior to emersion in liquid nitrogen (-196 degrees C). The freezing rate was -0.5 to -1.0 degrees C per minute, microfilariae remained viable for as long as, 212 and 375 days, survival rates were 94 to 98% and they were infective to Aedes togoi mosquitos. The infective larvae (L3) were obtained for 10-11 days after feeding at 28 degrees C room-temperature and the infection rate of L3 in test mosquitos was 22.4-30.6%. All DMSO should be removed from the freezing medium to restore microfilariae activity after freezing.

Abstract
The beta-turn formed by the amino acid residues 20-23 of the B-chain of insulin has been implicated as an important structural feature of the molecule. In other biologically active peptides, stabilization of beta-turns has resulted in increases in activity. We have synthesized three insulin analogues containing modifications which would be expected to increase the stability of the beta-turn. In two analogues, we have substituted alpha-aminoisobutyric acid (Aib) for the Glu residue normally present in position B21 or for the Arg residue normally present in position B22; in a third compound, we have replaced the Glu residue with its D-isomer. Biological evaluation of these compounds showed that [B21 Aib]insulin displays a potency ca. one-fourth that of natural insulin, while [B22 Aib]insulin is less than 10% as potent. In contrast, [B21 D-Glu]insulin is equipotent with natural insulin. We conclude that the beta-turn region of the insulin molecule normally possesses considerable flexibility, which may be necessary for it to assume a conformation commensurate with high biological activity. If this is the case, [B21 D-Glu]insulin may exhibit a stabilized geometry similar to that of natural insulin when bound to the insulin receptor.

Abstract
The use of a disposable non-electronic patient-controlled analgesia (PCA) device (Baxter) was evaluated in this study. Every patient under trial was instructed thoroughly how to use the PCA device before operation. The PCA device delivers a 25 mg IV injection of pethidine upon patient demand with a delay of 15 min between allowable administrations. The degree of patient satisfaction, the drug consumption, and the duration of using analgesia were compared with those in IM pethidine group. The results showed that, in the PCA group, the duration of using analgesic was longer; the drug consumption was greater (especially during the first 20 h after operation); and the degree of patient satisfaction was higher. The series comprised a total of 54 patients, 14 of whom complained of mild dizziness or nausea which did not require specific treatment. In sum, giving analgesic by the Baxter PCA device was a safe and effective alternative for IM analgesic in postoperative pain control.

Abstract
This paper reports the variation of peripheral T lymphocyte subsets in patients before and after operation under epidural anesthesia using OKT monoclonal antibodies (McAb). The results show that TH and TS after anesthesia and during surgery were lower than before anesthesia and in normal controls (P less than 0.05). The ratio of TH/TS after anesthesia and during operation were lower than before anesthesia (P less than 0.05), but there was no significant difference with normal controls (P greater than 0.05). Therefore, we consider that the decrease in TH cells was one of the reasons for decrease in patient immune function during anesthesia and surgery. Five to seven days after surgery, patient TH cell levels tended to normalize. This showed that this abnormality was transient and reversible. The results also indicated that emphasising prevention of infection in post-operational case, should be done during the first 5-7 days after surgery.

Abstract
Between 1 January 1980, and 30 September 1989, 93 cases of exposure to herbicides containing glyphosphate and surfactant ('Roundup') were treated at Changhua Christian Hospital. The average amount of the 41% solution of glyphosate herbicide ingested by non-survivors was 184 +/- 70 ml (range 85-200 ml), but much larger amounts (500 ml) were reported to have been ingested by some patients and only resulted in mild to moderate symptomatology. Accidental exposure was asymptomatic after dermal contact with spray (six cases), while mild oral discomfort occurred after accidental ingestion (13 cases). Intentional ingestion (80 cases) resulted in erosion of the gastrointestinal tract (66%), seen as sore throat (43%), dysphagia (31%), and gastrointestinal haemorrhage (8%). Other organs were affected less often (non-specific leucocytosis 65%, lung 23%, liver 19%, cardiovascular 18%, kidney 14%, and CNS 12%). There were seven deaths, all of which occurred within hours of ingestion, two before the patient arrived at the hospital. Deaths following ingestion of 'Roundup' alone were due to a syndrome that involved hypotension, unresponsive to intravenous fluids or vasopressor drugs, and sometimes pulmonary oedema, in the presence of normal central venous pressure.

Abstract
Aqueous soybean extracts were prepared from beans, previously treated by microwaves to almost inactivate their lipoxygenase. These soy milks thus obtained were then nutritionally evaluated. All soy milks studied showed lower protein, fat, ash and total solids contents, as compared to a control milk prepared from soy beans not processed by microwaves. The milk obtained from soybeans with 8.7% initial moisture, treated by microwaves for 240 seconds, had the best total chemical score and the highest apparent methionine availability, as well as PER. The complete inactivation of the trypsin inhibitor activity was achieved with the milk prepared from soybeans with 56.8% initial moisture, subjected to microwave treatment for 180 seconds. On the other hand, the milk obtained from soybeans with 38.8% initial moisture, processed by microwaves for 180 seconds, resulted to have the highest, in vitro, protein digestibility.

Abstract
A long term follow-up for 42 cases of ulnar nerve repair was reported in this article, and the reason of bad function were analysed. They are: 1. As long as the injured ulnar nerve was sutured perfectly and without delay, the result would be satisfying. 2. The follow-up examination of the repaired nerve showed all the paralysed intrinsic muscles would recover in certain extent. Abductor digiti quinti, adductor pollicis and flexor digiti quinti brevis usually restored easily. Among the intrinsic muscles the best result of the first dorsal interosseous and the first palmar interosseous muscles were obtained. The functional recovery of the second and third palmar interosseous muscles usually was poor. 3. After repairing of the injured ulnar nerve, recovery of the claw hand deformity usually takes long time, so the operative correction of the deformity should not be performed until 2.5 years.

Abstract
A 60 year-old hypertensive male was operated with resection of epidermoid carcinoma of buccal mucosa. He was expired postoperation complicated with left middle cerebral artery infarction. The cerebral infarction may be induced by acute hypotension, improper position during operation and underlying disease associated with old age. Prevention methods included preoperative evaluation, immediately injection vasopressor when acute hypotension occurred during anesthesia, and avoidance of improper position to compress vertebral or carotid artery which may leading to cerebral perfusion insufficiency.

Abstract
The striated muscle tropomyosin-enriched microfilaments were isolated from developing muscles in ovo by the previously described method with a monoclonal antibody against striated muscle isoforms of tropomyosin (Lin & Lin, 1986). Two-dimensional gel analysis of the isolated microfilaments from developing heart, thigh and breast muscles revealed the coexistence of non-muscle isoforms of tropomyosin and actin throughout all stages of embryogenesis. A small but significant amount of skeletal muscle isoforms (alpha, beta) of tropomyosins and their phosphorylated forms was detected in the microfilaments isolated from hearts of 6-15-day-old embryos. These skeletal isoforms of tropomyosins disappeared after this stage of embryogenesis. In addition, we also detected both embryonic and adult isoforms of troponin T in early developing hearts. In developing thigh and breast muscles, the presence of non-muscle tropomyosin isoforms 2, 3a and 3b in the isolated microfilaments was apparent. The contents of tropomyosin isoform 2 were decreased with development and this non-muscle isoform completely disappeared at the 15th day of embryogenesis. On the other hand, the non-muscle tropomyosin isoforms 3a and 3b were present throughout all stages of development. Double-label immunofluorescence microscopy with monoclonal CH1 (anti-striated muscle isoforms of tropomyosin) and CG beta 6 (anti-non-muscle isoforms of tropomyosin) on the isolated, glycerinated skeletal and cardiac muscle cells of 10-day-old or 13-day-old embryos confirmed the colocalization of muscle and non-muscle isoforms of tropomyosins within the same cells. These results suggest that different isoforms of actin and tropomyosin can assemble into a class of microfilaments (i.e. striated muscle tropomyosin-enriched microfilaments) in ovo, which may transform into the thin filaments of mature muscle cells.

Abstract
Seventy-one patients with 80 lower limbs clinically suspected of deep venous thrombosis (DVT) were investigated by both Doppler ultrasound and venography. Sixty-seven lower limbs demonstrated by venography to have DVT, in 5 the thrombus was confined to the calf, and all were detected by the Doppler ultrasound. In 62 limbs thrombus extended into the popliteal and more proximal veins, the Doppler ultrasound detected 61 of them, a sensitivity of 98%. Venography showed a deep venous system without any evidence of thrombosis in 13, the Doppler findings were normal in all of the 13 lower limbs, a specificity of 100%. We found that the examination of the popliteal vein with patient in a semi-lateral prone position was important in detecting the presence of thrombosis in popliteal and more proximal vein.

Abstract
Peripheral T lymphocyte subsets in 60 cases of Graves' disease (GD) and 16 cases of Hashimoto's thyroiditis (HT) were determined by the use of OKT monoclonal antibodies (McAb). The results showed that in both diseases OKT3 cells (total T cells) and OKT8 cells (suppressor T cells, TS cells) were lower and the ratio of OKT4 cells (helper T cells, TH cells) OKT8 cells was much higher than those in normal controls. GD patients who were treated with antithyroid drugs (ATD) and whose serum T3, T4 recovered to normal, could be further divided into subgroups of high OKT4/OKT8 cell ratio and of normal ratio. The pathogenesis, treatment and relapse of autoimmune thyroid diseases (AITD) were discussed in this paper on the basis of the results.

Abstract
Budd-Chiari syndrome is an unusual form of portal hypertension caused by occlusion of the hepatic venous outflow, and it is often confused with portal hypertension caused by liver cirrhosis. Its prognosis is poor, and optimal therapy remains to be established. This is a report of 100 confirmed cases of this syndrome treated from December 1982 to March 1988 at two vascular centers in China. Sixty-two male and 38 female patients, 15 to 62 years of age (mean age, 32.6 years) were treated. Seventy-six patients had intractable ascites, 56 had esophageal varices, and 22 had upper gastrointestinal bleeding. There were 37 cases of membranous obstruction, 57 cases of occlusion of the inferior vena cava above the confluence of the hepatic veins, and 6 cases of occlusion of the hepatic veins. Eighty-one patients were operated on. Operative mortality rate was 8.6% (7/81). Follow-up from 2 to 66 months revealed that 58 of the patients operated on (72%) had good results, whereas 11 of 19 (58%) patients treated nonoperatively died within 2 months after admission. On the basis of these data we conclude that the operative procedure must be tailored to the cause and underlying pathologic characteristics. Mesoatrial shunting is the operation of choice for patients with occlusion of the retrohepatic inferior vena cava and hepatic veins, and inferior vena cava--atrial shunting is the operation of choice for patients with occlusion of the inferior vena cava and patency of the hepatic veins. Membranotomy is used for patients with inferior vena cava webbing, and mesocaval shunting is used for patients with intrahepatic venous occlusion only.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Cellular composition of 31 cases of human atherosclerotic lesion was studied by immunohistochemical technique. Specimens were taken from the thoracic and abdominal aortas of necrosis. Four monoclonal antibodies were used to identify cell types. Monocytes/macrophages reacting with anti-Leu-M1 or anti-alpha-1-ACT were found in early lesions and some activated areas such as the peripheral region of bottom of atheromatous plagues of the advanced lesions. Some foamy cells also showed positive to alpha-1-ACT. In addition T lymphocytes reacting with anti-UCHL-1 were detected in the early lesions and some activated areas of advanced plaques, and both types of cells were more common in the early than in the advanced lesions. Other types of leukocytes were scanty in both early and advanced atheromatous lesions. In conclusion, the presence of a variable number of monocytes/macrophages and T lymphocytes in human atherosclerotic lesion may represent a cell-mediated immune response which may be very important in the initiation and progression of atherosclerotic lesion.

Abstract
The blood meals of mosquito vectors of W. bancrofti and B. malayi were determined by performing CIEP of the eluant of crushed mosquitoes in filter paper against rabbit anti-human, cow and pig sera. The mosquitoes were collected from houses, cowsheds and pigpens in two counties in Guizhou Province. It was shown that all three species fed on blood from humans, cows and pigs with different preference. While An sinensis fed more on cows, Cx. fatigans and An. lesteri fed on the hosts that were nearby, i.e., Cx. fatigans caught from households fed more on humans, and those collected from cowsheds or pigpens fed more on cows and pigs, respectively.

Abstract
When chronic glomerulonephritis (CGN) proceeds to chronic renal failure (CRF), there are decline of fibrinolytic activity and deposition of fibrin in glomeruli with resulting thromboembolic lesions. 46 CGN patients with complicating CRF were thus treated with defibrase made from viper venom. Defibrase in a dose of 0.025 unit/kg dissolved in 250 ml 10% glucose was infused slowly once every 3 days in a total of 6 times. After the treatment, BUN and serum creatinine levels decreased, creatinine cleance improved and the clinical manifestations of uremia alleviated or disappeared. In some patients there were increase of hemoglobin concentration and decrease of urinary protein excretion. Hypertension was controlled in 17 out of 20 patients treated in combination with captopril. Level of plasma fibrinogen was significantly reduced after defibrase administration, but the reduction was not related to the therapeutic effect. Urinary output was increased in most of the patients, being related to the therapeutic effect. The authors are of the opinion that renal function may be improved in CGN patients after defibrase treatment due probably to elimination of fibrin deposition and resolution of thromboembolic lesions in glomeruli. However, a suitable dose has to be determined as there is no effective way to monitor the most dreaded complication of defibrase therapy bleeding.

Abstract
A large scale, phased investigation of NORPLANT contraceptive systems was conducted in the People's Republic of China. The first phase comprehended 1,200 women in four cities. Expanded trials included 11,918 women at 12 major centers and at sub-centers by 31 May 1987. At that date 4,676 NORPLANT capsule subjects and 1,089 rod subjects had completed one year of use, 1,381 capsule acceptors had completed two years as had 197 rod users. Gross pregnancy rates were less than 0.1 per 100 for each implant type both at one and at two years. Continuation rates were 94 per 100 for each implant type at one year, and were 82.0 and 83.6 per 100 among users of NORPLANT capsule and rod implants, respectively, at two years. Disruption of menstrual function was the dominant reason for termination, but mean hemoglobin levels increased in each of the nine centers reporting values at admission and at one year. First year gross cumulative termination rates for medical reasons were 1.2 to 1.3 per 100, reaching 3.8 and 5.6 per 100 for capsule and rod implants, respectively, at two years. Microdose contraception with these levonorgestrel-releasing implants appears to be a highly acceptable and effective modality suitable for Chinese women. NORPLANT implants are now approved by the national drug regulatory agency for general use in China.

Abstract
A subpopulation of purified, interepithelial lymphocytes from porcine small intestinal mucosa contained cytoplasmic granules. Toluidine blue staining revealed metachromatic granules in 13.64% (606/4,450) cells. The cells had scant organelles, a single large nucleus with obvious invagination of the nuclear membrane, and prominent chromatin. Each cell contained 1 to 10 cytoplasmic membrane-bound granules, 0.6 to 1.5 micron in diameter. These findings indicated that the granular mucosal lymphocytes are related morphologically to mucosal mast cells. The presence of serotonin in the granules, confirmed by the serotonin releasing test, provided functional evidence that granular mucosal lymphocytes are related to mucosal mast cells.
