Abstract
BACKGROUND/AIMS Norfloxacin is useful to prevent infections in hospitalized cirrhotic patients with low ascitic fluid protein concentrations. It is also effective in preventing the recurrence of spontaneous bacterial peritonitis. The aim of our study was to determine the efficacy of norfloxacin in the primary prophylaxis of gram-negative bacilli infections in cirrhotic patients with low ascitic fluid protein levels (<15 g/l). METHODS One hundred and seven patients were randomized to receive norfloxacin (400 mg/day; n=53) or placebo (n=54) for 6 months. The patients had no history of infection since cirrhosis diagnosis and no active infection. RESULTS The probability of gram-negative infection was significantly lower among patients treated with norfloxacin than among those treated with placebo. Six gram-negative bacilli infections occurred in the placebo group and none in the treatment group. Severe infections (spontaneous bacterial peritonitis, neutrocytic ascites and bacteremia) developed in nine patients in the placebo group (17%) and in one patient in the norfloxacin group (2%; p<0.03). There was no between-group difference in the overall rate of infection or in survival. In ten patients from the norfloxacin group, gram-negative bacilli not present in baseline stool cultures were transiently isolated in follow-up cultures. CONCLUSIONS These data show that primary prophylaxis with norfloxacin for 6 months is effective in the prevention of infections caused by gram-negative bacilli in cirrhotic patients with low ascitic fluid total protein levels.

Abstract
Ascites is an uncommon feature of hypothyroidism. We report two patients with hypothyroidism revealed by ascites. Among the 44 myxedema ascites cases found in the literature, there were observed 17 cases of ascites as the first manifestation of hypothyroidism. In this rare presentation of hypothyroidism, diagnosis is often delayed. Biological analysis of ascites usually shows high protein and cholesterol concentrations and a low or high cell count with a high proportion of lymphocytes. An increase in capillary permeability may play a role in the pathogenesis of ascites.

Abstract
BACKGROUND We have previously shown that basic fibroblast growth factor (FGF-2) enhances corneal epithelial healing in different experimental models in vivo. In order to study the healing effect of this growth factor in pathological conditions of the cornea, we investigated whether topical application of FGF-2 could affect herpes keratitis in rabbits. Since HSV-1 infection is prevented in vitro by incubation with heparin, we also topically applied heparin and suramin, considering the similar interaction of herpes simplex virus and FGF-2 with cell membrane-anchored heparan sulfate. METHODS After virus inoculation with a human BEY.2 strain, rabbits were treated with either FGF-2 (200 ng to 2 micrograms/application), heparin (250 micrograms/application) or suramin (250 micrograms/application) 4 times daily until day 14. Acyclovir and placebo administrations served as controls (n = 48 rabbits). Computerized ulcer surface analysis, clinical observations and virus recovery assays were performed. RESULTS Topical FGF-2, heparin and suramin treatment revealed a significant reduction in peak ulcer sizes, and complete epithelial healing was achieved earlier than in placebo-treated corneas. However, no significant antiviral effect of FGF-2, heparin and suramin was detectable in plaque assays from conjunctival swabs. CONCLUSIONS These experiments demonstrate that FGF-2 is effective in promoting herpetic epithelial ulcer healing, either due to its proliferative effects on epithelial cells or indirectly by occupying the sites on cell surface heparan sulfate necessary for the attachment of the virion. The latter mechanism of action is presumably the reason for the similar effect of heparin and suramin.

Abstract
The aim of this study was to evaluate the antihypertensive effect of drugs according to the initial ambulatory blood pressure (BP) level. After a 15-day placebo run-in period, 105 patients with moderate essential hypertension (mean age, 52 years) underwent 24-h BP monitoring (spacelabs: 1 measure/15 min). Patients were subdivided into two groups: the "High" group, with 24-h mean values of systolic BP (SBP) > 137 or diastolic BP (DBP) > 87 mm Hg, and the "Low" group, with SBP < or = 137 and DBP < or = 87 mm Hg. All patients received, in a random and double-blind design, either bisoprolol (10 mg q.d.) or lisinopril (20 mg q.d.) for 8 weeks. At the end of this active treatment period, office and ambulatory BP measurements were performed. Casual measurements revealed similar BP decreases in all subgroups receiving bisoprolol and lisinopril; BP monitoring showed that the antihypertensive effect depended on the baseline mean 24-h value; -15/-12 mm Hg for bisoprolol and -18/-13 mm Hg for lisinopril in the High group; -7/-6 mm Hg for bisoprolol and -6/-6 mm Hg for lisinopril in the Low group. This study shows that the antihypertensive effect depended on initial ambulatory BP values, with a lower BP decrease in the Low group. Assessment of the antihypertensive effect on ambulatory BP is useful in clinical trials.

Abstract
Primary lymphomas rarely affect the heart. The myocardial disease is usually latent and the diagnosis is based on post mortem observations. The cardiac symptoms do not reveal the disease and symptomatology is not specific. Our observation shows the complementarity of non invasive techniques, for a better screening of cardiac tumoral forms. Although echocardiography is the main examination, CT scan provides a detection of infiltrative forms and of extracardiac extension. Concurrently, MRI remains the method of choice to display beginning infiltrative forms, revealed by pericardial effusion in AIDS disease.

Abstract
Non-Hodgkin's lymphoma is common in patients with human immuno-deficiency virus infection, but an intracardiac localisation is rare. In this case, the malignant lymphoma presented with a degradation of the patient's condition and signs of right-sided cardiac failure. Echocardiography showed a polylobed mass invading the right ventricle. Computerised tomography provided detailed information of the extension of the lymphoma in the different cardiac chambers. The patient died after a few days of a low cardiac output state. The malignant nature of the tumour was confirmed at biopsy. This case of cardiac lymphoma in a patient with immunodepression confirms the fatal character of this condition in the very short term after the appearance of the first clinical signs, the value of echocardiography in the diagnosis and the difficulty in implementing any effective therapeutic measure.

Abstract
The authors studied erythrocyte aggregation in 62 patients suffering from hemorrhoidal disease, distributed on the basis of proctoscopy findings between three groups (recent uncomplicated congestive attack, recent thrombosed hemorrhoid, stage IIb or III chronic prolapse). This hemorheological parameter is a sensitive marker of circulatory stasis. Values measured were compared with those obtained in 21 healthy subjects. Erythrocyte aggregation index was significantly higher in patients than in controls (31.6 +/- 6.8 versus 27.7 +/- 4.4) (p < 0.05). This difference was due essentially to increased values in patients with acute hemorrhoid problems. A parallel increase in blood fibrinogen was found in these same patients. Hemorheological changes could predispose to worsening of venous stasis in the hemorrhoidal circulation and participate in the onset or spread of thrombotic processes.

Abstract
A cardiac tumour of the interventricular septum was detected in a young woman presenting with an ejectional systolic murmur. Surgical ablation was carried out before a precise diagnosis was made. Histopathological analysis of the surgical specimen confirmed a hydatid cyst. The main complication was complete atrioventricular block. This case underlines the difficulty of making the diagnosis of intracardiac hydatid disease in a non-specific context, because of the long period of clinical latency, despite the considerable aid of echocardiography and other medical imaging techniques (CT scan and magnetic resonance imaging.

Abstract
A chronic administration of three ganciclovir gels (0.2%, 0.05%, 0.0125%) was compared with a placebo gel and a 3% acyclovir ophthalmic ointment in the treatment of HSV-1 rabbit keratitis. All the ganciclovir gels showed a clinical efficacy: a significant reduction of the corneal ulcer area, clouding and vascularization (p < 0.05) and a fast inhibition of HSV isolates into tear film with the 0.2% and 0.05% ganciclovir gels. However the efficacy was slower than using acyclovir ointment. No significant difference could be shown between the 0.2% and 0.05% ganciclovir gels or the 0.05% ganciclovir gel and the acyclovir treatment on viral isolation, when it was performed on pooled samples. The distribution of ganciclovir and acyclovir into the rabbit eyes (HPLC methods), were similar but markedly higher in solid tissues than ocular fluids. It might explain the recovery from tissue damages. The mean corneal ganciclovir concentrations were largely higher than ED 50 of ganciclovir for HSV-1. No toxicity was expected, due to very limited systemic availability. This study suggests a comparable activity on HSV-1 superficial keratitis between 0.05%, 0.2% ganciclovir gels and 3% acyclovir ointment. Higher concentration of ganciclovir gels are probably necessary in order to treat the HSV-1 kerato-uveitis.

Abstract
The emergence of cross-resistance to various antiviral drugs was investigated both in vivo and in vitro for herpes simplex virus type 1 (HSV1) resistant to idoxuridine (IUdR 0.24%) obtained by seven successive passages (from P0 to P7) in rabbit keratitis treated by IUdR. The viral population obtained at the seventh IUdR passage (P7) showed an activity of the thymidine kinase (TK) reduced to 5.6% of the parental strain (PO); moreover, most of the clones of P7 showed an altered TK phenotype determined by the [125I]iododeoxycytidine (IDC) procedure. In rabbit keratitis, IUdR-resistant viral population P7 showed cross-resistance to bromovinyl desoxyuridine (BVDU) (0.5%) and to acyclovir (ACV) (3%). Under trifluorothymidine (1%) treatment, P7 showed an intermediate sensitivity. HSV1 at P7 remained sensitive to adenine arabinoside (Ara A) (3%) and to dihydroxy-propoxymethylguanine used at high concentration (3%). The in vitro sensitivity determination to various antiviral drugs was investigated by dye-uptake assay for the initial viral population PO and for HSV1 collected under IUdR treatment at the third (P3) and the seventh (P7) passages. Cross-resistance to TK-dependent drugs, such as IDC, BVDU, and ACV were found at P7. P7 remained sensitive to Ara A and to phosphonoformic acids antiviral drugs known not to be dependent on viral TK.

Abstract
BACKGROUND Reports on the natural history of herpes zoster ophthalmicus stress its high morbidity related to vicious scars on eyelids, ocular complications, and post-herpetic neuralgia. Early treatment with oral acyclovir is effective, but the optimal duration of treatment has not been defined. METHODS The authors performed a bicentric, prospective, randomized, double-masked study of 86 patients with acute herpes zoster ophthalmicus, within 72 hours of skin eruption, who received oral acyclovir (800 mg 5 times daily), either for 7 days (plus 7 days oral placebo) or for 14 days. All patients concomitantly received ophthalmic 3% acyclovir ointment; follow-up was at least 6 months. RESULTS Statistical analyses of subjective symptoms, skin lesions, and ocular complications showed no significant differences between the groups, suggesting that a 7-day course of treatment was sufficient. Drug tolerance was good. Pooled data from both groups corroborated earlier reports that prompt treatment with oral acyclovir reduces the severity of the skin eruption, the incidence and severity of late ocular manifestations, and the intensity of postherpetic neuralgia. At 6 months, late ocular inflammatory complications were seen in 29.1% of our 86 patients, versus 50% to 71% of untreated patients described by others. Only 13% of our patients experienced post-herpetic neuralgia, which in no case required the use of analgesics. CONCLUSION The authors believe it is not useful to prolong treatment with 800 mg of oral acyclovir 5 times daily for more than 7 days in herpes zoster ophthalmicus. This study confirms the efficacy of oral acyclovir not only against skin lesions and ocular complications, but also against postherpetic neuralgia in herpes zoster ophthalmicus.

Abstract
In a prospective study, we analysed the anorectal lesions observed in 148 human immunodeficiency virus-infected patients and compared the data with those reported in the literature. The majority of the patients (97.3%) were homosexual or bisexual men. The mean age of the population was 34.2 years. A history of previous sexually transmitted diseases was found in 79.7% of the male patients. The stage of HIV-related disease, according to the Centers for Disease Control classification, could be determined in 141 patients: 54.6% were stage II, 3.5% stage III and 41.8% stage IV. Anal condylomata were the most frequent manifestation, affecting 29.7% of the patients, 7.1% of whom showed moderate to severe dysplasia. The types were mainly 6, 11, 16 and 18, but types 31, 35 and 39 were also observed. Ulcerations were the most frequent non-condylomatous lesions, occurring in 41 patients; most (60%) were due to herpes viruses, and a large minority (21%) to cytomegalovirus. The etiology could not be determined in five cases. Anal sepsis was present in 11.4%, haemorrhoidal disease in 16.8% and fissures in 6%. Six patients developed Kaposi's sarcoma and seven, non-Hodgkin's lymphoma. No anal cancers were observed. Finally, wound healing was slowed in the patients operated on for haemorrhoids, fissures and suppuration. No statistical analysis could be performed because of the small number of patients.

Abstract
In order to investigate the mechanism by which the inorganic content of the bone is reduced in chronic alcoholism, the authors assayed osteocalcin in 60 chronic alcoholics. The level was significantly lower than in control subjects. There was no significant difference between levels in cirrhotics and in non-cirrhotic alcoholics. There was a negative correlation between osteocalcin and gamma GT levels. There was no correlation between osteocalcin and blood calcium, blood phosphorus, ALAT, ASAT, alkaline phosphatase, 5'-nucleotidase, albumin or bilirubin levels, or with the prothrombin time. These results suggest a direct impact of alcohol on the osteoblast.

Abstract
We report a case of isolated colonic Kaposi's sarcoma in a 36-year-old HIV-negative woman with refractory Crohn's disease of the colon and perineum following 11 months' treatment with azathioprine. The clinical features of this case are quite different from those classically described in Kaposi's sarcoma. Among the known risk factors, iatrogenic immunosuppression would appear to be the most probable.

Abstract
This paper suggests that the difficulties associated with the application of formal strategic planning in public professional service organizations may have been underestimated in much of the literature. A survey of written strategic plans produced by Canadian hospitals showed that these plans were often heavily oriented towards expansion, ambiguous and rather loosely integrated, leading to questions concerning their realism and utility as a basis for strategic decisions. This phenomenon seems symptomatic of the complex (and often highly political) decision making environment faced by hospital administrators (and by managers of other professional service organizations such as universities and social service agencies). It is concluded that the benefits of formal planning may be different and less tangible for these organizations than for private business.

Abstract
The acquisition of drug resistance in vivo was investigated by 7 serial passages (from P0 to P7) of herpes simplex virus (HSV-1) in rabbit cornea treated with either IUdR (idoxuridine), IDC (idoxycytidine), ACV (acyclovir), TFT (trifluridine), or Ara A (adenine arabinoside). Therapeutic failure was acquired gradually: at P3 for IUdR, at P4 for ACV and at P5 for TFT. At P7, viral thymidine kinase (TK) activity was reduced to 5.6% of the parental strain for IUdR, to 7.5% for ACV and to 4.6% for TFT treatment. No signs of clinical unresponsiveness occurred with IDC or Ara A. The in vitro determination of antiviral drug sensitivity performed by the dye-uptake assay on HSV isolates at each passage showed a correlation between the increase in the 50% effective dose (ED50) and the increase of ulcer area grade at each passage under antiviral drug (p less than 0.1). Both IUdR- and TFT-resistant HSV1 developed cross-resistances to TK dependent drugs. However ACV-resistant HSV1 did not show cross-resistance to other antiviral TK dependent drugs. The acquisition of the cross-resistances is discussed, and the practical implications in case of therapeutic failures are suggested.

Abstract
Lesions due to cytomegalovirus (CMV) are frequent in the immunocompromised patient. This is particularly the case in patients with AIDS, where the colon and rectum are the regions most often involved. The authors report six cases of anal ulcerations due to CMV in patients with AIDS. These lesions, confirmed histologically, were either isolated or associated with other localizations. Treatment is based on specific antiviral agents but resistance and recurrence can occur. The current report underlines the importance of histologic examination of anal lesions in HIV-infected subjects.

Abstract
A case of idiopathic portal hypertension associated with connective disease resembling systemic lupus erythematosus is described. The patient was a 50-year-old woman with splenomegaly, ascites, esophageal varices, and pancytopenia, but without extrahepatic portal obstruction or cirrhosis of the liver. Electron microscopy of the liver showed perisinusoidal fibrosis. High titers of autoantibodies against proliferating cell nuclear antigen (PCNA) were found in the sera as well as in ascites; anti-DNA antibodies appeared after anti-PCNA antibodies and remained thereafter at a moderate titer. The possibility of an immunological process in the pathogenesis of idiopathic portal hypertension is discussed.

Abstract
The authors describe their hemorrhoidectomy technique, a modification of Milligan-Morgan. It differs by the association of a posterior anoplasty (with internal sphincterotomy in the case of a fissure or sphincter hypertonia) and of a sub-mucocutaneous dissection of the security bridges. They report on their experience with 410 operations carried out during the year 1985. Immediate complications are mainly hemorrhage (2.68%) and urinary problems (9%). Average cicatrization time is about six weeks. At one year, there were no relapses nor fissures. A moderate stenosis was observed in 1.45% of the cases, and a hypocontinence to flatus in 2.3%. Use of a CO2 laser does not result in any modification of these results.

Abstract
20 patients with supraventricular tachycardia, received one to three intravenous injections of 0.5 mg/kg of sotalol. This group included 8 atrial fibrillations, 5 atrial flutters, 2 systolic tachycardias and 5 junctional tachycardias. Return to a normal sinus rhythm is obtained in 2 of the 8 patients with atrial fibrillation while a decreased heart rate under 100 per minute is noted in 3 of them. Among the 5 patients with atrial flutter, only one returned to a normal sinus rhythm and in 2 the tachycardia decreased. In the 2 patients with systolic tachycardia, the heart rate decreased without return to a normal sinus rhythm while the heart rate decreased in all 5 cases of junctional tachycardia. A left ventricular failure with hypotension, a bradycardia at 30/min. and a transient left bundle branch block were observed during treatment. The bundle branch block is explained by an increased ventricular effective, refractory period induced by this beta-blocker. Intravenous sotalol appears as an interesting alternative in the treatment of supraventricular tachycardias with an efficacy of about 70 p. cent; it is well tolerated if the contraindications of the beta-blockers are respected.

Abstract
The pharmacokinetics of netilmicin after intramuscular injection (2 mg/kg) was investigated comparatively in cirrhotic patients with or without ascites, and in healthy subjects. In patients with ascites, the same pharmacokinetic parameters were measured after the ascites had been cured. Twenty-four hours after intramuscular injection, the residual levels in cirrhotic patients were moderately higher than in controls, showing that liver failure or ascites did not significantly modify the pharmacokinetics of netilmicin. Serum concentrations were bactericidal. The ascitic fluid level was lower than the therapeutic range, but it was sustained for nearly 24 hours after intraperitoneal injection (2 mg/kg). These results indicate that netilmicin may be administered to cirrhotic patients without peritoneal infection using the same regimen as in healthy subjects. The peritoneal route may be preferable in case of peritoneal infection.

Abstract
A case of subacute left ventricular rupture on the 4th day of an inaugural antero-septal infarction in a 63-year old woman is reported. The diagnosis, suggested by cardiovascular collapse with acute tamponade, was confirmed by echocardiography. Haemodynamic stability was maintained by needle aspiration followed by pericardial drainage, and right heart catheterization long enough for the patient to be transported to a Cardiovascular Surgery unit where surgical repair was successfully performed 9 hours after the rupture. The elements for a positive diagnosis, the value of echocardiography, the various surgical procedures and the favourable long-term prognosis in patients operated upon are discussed.

Abstract
The effects of repeated topical idoxuridine (IDU) administration of HSV1 strain sensitivity were investigated during 6 serial passages (P1 to P6) in the rabbit. By comparison to placebo treated rabbits, a delay in ulcer cicatrization appeared at P2 and clinical resistance was completed at P3. Clinical cross resistance to acyclovir (ACV) was also tested and demonstrated at P7. In vitro, a plaque reduction test on Vero cells using directly the tear film HSV populations allowed the prediction of the resistance by an early rise in the effective dose 90% (ED 90) value anticipating that in ED 50%. An ED 50 determination by dye-uptake assay on P6 HSV isolate demonstrated a cross resistance to viral thymidine kinase (TK) dependent drugs without any change in Ara-A and PFA sensitivity, according to a 23% TK activity at P6. At the last passage the HSV drug resistant population had an unrestricted corneal pathogenicity. A return to IDU and ACV in vitro sensitivity was demonstrated in group control animals at P2 but not at P4 or P6.

Abstract
Twenty four in-patients with an endogenous or non endogenous depressive syndrome (9 and 15, respectively) were treated in hospital for 21 days with various dosages regimens of clomipramine. Plasma concentrations of clomipramine and demethylclomipramine were determined once a week in blood samples. Therapeutic effects were assessed with Hamilton Rating Scale. At day 21, optimal therapeutic effect was observed when the sum of clomipramine and demethylclomipramine plasma levels was situated between 200-400 ng/ml.

Abstract
During February 1979 to December 1982 we studied the karyotype of 706 psychiatric adult patients without making a clinical selection. We found a chromosomial mosaïc aberration in 37 cases, concerning one leukocyte mitosis for ten studied cells : so a proportion of 5.2% cases. There do not exist statistics concerning the general population's mosaïc aberrations but in the same population the proportion of the homogeneous aberrations is near 0.5%, so 10 times lower than the proportion that we observed. The largest number of aberrations found concern the gonosomes, essentially some monosomics 45,XO or some trisomics 47,3X, among women who present a maniac depressive psychosis or another type of depression.

Abstract
The negative Lewis blood type is meaningfully more frequent with our psychiatric patients than with the general population. The theoretical interest of this fact is certain for the reason of two particularities of this blood type. It is not genetically and definitely determined at birth: the absence of passing over negativity through positivity seems to constitute a factor in favour of the blossoming of a psychiatric pathology. It is in connection with the secretory aptitude of some cells: this fact opens some perspectives for the comprehension of the deficits in the neurotransmitters. The application of theory will be confirmed by others statistics. But it indeed appears that the control of the chemiotherapy is more difficult with the negative Lewis blood type patients.

Abstract
The authors report a case of fibrolamellar carcinoma of the liver in a young woman with bilateral lung metastases. This tumour was surgically unremovable. Presently, after a chemotherapy with adriamycin and mitomycin, this patient is in good health, two years after initial diagnosis. Review of the literature shows that fibrolamellar carcinoma of the liver occurs mainly in young patients. This tumor is characterised by large polygonal eosinophilic hepatocytes and an abundant fibrous stroma. It can be confused with focal nodular hyperplasia. Resection of the tumor and the methodical, repeated resections of metastases must be performed when possible. Prognosis of this tumor is better than that of the other variants of hepatocellular carcinoma.

Abstract
The influence of intravenous infusion of branched-chain amino acids (BCAAs) on brain function in patients with liver cirrhosis and acute hepatic encephalopathy was examined using a double-blind, randomized study design. Five medical centers in France and Sweden participated, and 50 patients were studied. The patients received either BCAAs (40 gm per day) in 5% glucose or 5% glucose alone (placebo) for 5 days or until "wake up". Nutritional support was provided with equal proportions of carbohydrate and fat. During BCAA administration, plasma concentrations of aromatic amino acids and methionine fell (20 to 40%, p less than 0.05 to 0.01), and the ratio of BCAAs to aromatic amino acid concentrations increased significantly. Clinical improvement was seen in 14 of 25 BCAA-treated patients and in 12 of 25 patients receiving placebo (N.S.). EEG responses were similar in the two groups during treatment. In the BCAA group, 10 of 25 patients died in the course of the study, compared to 5 of 25 in the placebo group (N.S.); six patients died from encephalopathy in the BCAA group as compared to three among placebo-treated patients. It is concluded that BCAA administration, in the dose and composition employed in the present study, reduces the concentrations of aromatic amino acids but neither improves cerebral function nor decreases mortality in patients with hepatic encephalopathy.

Abstract
In a 48-years old woman, intermittent rifampicin treatment induced an immunoallergic reaction with digestive disorders, haemolysis, acute renal failure and prolonged prothrombin time. The reintroduction of rifampicin, 17 days later, resulted in a similar, though more severe, reaction associated with diffuse haemorrhages from disseminated intravascular coagulation, this association being exceptional. The responsibility of rifampicin was demonstrated by the chronological relationship between clinical symptoms and administration of the drug, and by the presence in the patient's serum of anti-rifampicin antibodies. The antigen-antibody reaction with complement activation and haemolysis probably explains the disseminated intravascular coagulation.

Abstract
Intramural abscesses of the rectum developed in the complex longitudinal layer may be isolated or associated with a transphincteric fistula. They may be acute or subacute and are diagnosed by intrarectal palpation. The only treatment is surgical: the abscess is opened into the rectal cavity, except in case of association with suprasphincteric fistula, when it must be drained through the skin. Postoperative complications are minor ones and relapses are rare (1.75% of cases).

Abstract
Ammonia, amino acids (AA), and middle molecules (MM) have been implicated in the pathogenesis of experimentally induced acute hepatic coma in the pig. Hemodialysis (HD) using either a low- (Cuprophan = CU) or a high-permeability (polyacrylonitrile = AN 69) membrane has demonstrated the role of MM. Selective hemodialysis (SHD) of AA or NH3 and MM was performed by adding either NH3 (group I) or AA (group II) to the dialysate during AN 69 HD; for MM, SHD only was performed by adding NH3 and AA to the dialysate (group III). In group I the brain levels of tyrosine were similar to those in undialyzed animals with decreased striatal dopamine and decreased norepinephrine in the midbrain only. Brain tryptophan was higher than normal, but brain levels of 5-hydroxytryptamine and 5-hydroxyindoleacetic acid (5-HT, 5-HIAA) were within normal limits. In group II, despite an efficient NH3 clearance, brain NH3 levels were as high as in group I and did not correlate with plasma levels. Brain tyrosine (despite tyrosine overload of the dialysate) was lower than in group I; striatal dopamine decreased (but to a lesser extent than in group I), and norepinephrine was normal. Brain tryptophan was higher than normal, with an increase in brain 5-HT and 5-HIAA. In group III, results were similar to group I, except for a limited increase of 5-HT in the pons. Brain octopamine levels increased only in undialyzed and CU-HD animals, demonstrating a specific relation with MM. These experiments demonstrate the interrelationship between NH3 and neutral AA with regard to passage through the blood-brain barrier and to intracerebral metabolism.
