Histologic changes in the guinea pig gastrointestinal tract following 1 weeks' administration of chlorpromazine, haloperidol or atropine.

A comparison was made between the toxic effects of chronic chlorpromazine, haloperidol or atropine on the guinea pig intestinal tract. Chlorpromazine, administered at a dose of 30 mg/kg/day, IP for 7 days, produced marked pathologic changes in the guinea pig cecum, consisting of inflammation, edema and hemorrhage. None of these effects were noted when haloperidol, 2 or 10 mg/kg/day or atropine 30 mg/kg/day were similarly administered. Similar toxic effects may occur in humans on long-term chlorpromazine or other phenothiazine therapy, thereby accounting for the paralytic ileus observed with these drugs.

Effect of cyclophosphamide in active nonviral cirrhosis.

The immunologic effects of cyclophosphamide were studied in 16 patients with active nonviral liver cirrhosis with a view to improving the pathogenetic treatment of these diseases. After months of cyclophosphamide administration first in doses of 100 mg/day (for 14 days) then in doses of 200 mg per week, the hypergammaglobulinemia present at entry was reduced significantly from 2.55 +/- 0.35 g/dl to 1.71 +/- 0.17 g/dl concomitantly with the proportional increase of the active suppressor T lymphocytes, from 29.3 +/- 3.59% to 38.0 +/- 2.1%. The use of smaller doses of cyclophosphamide, i.e., 200 mg/week, allowed the maintenance of its immunosuppressive properties and prevented its side effects.

The clearance of colloidal particles by Kupffer cells in collagen disease.

The Kupffer cells clearance of colloidal 198Au particles with a diameter of 200-300 A was estimated in 14 subjects with different collagen diseases: 7 without previous treatment and 7 under immunodepressive treatment compared to 10 controls. No difference between the subjects with collagen disease and controls was observed. The group with collagen disease under immunodepressive treatment has lower Kupffer cells clearance for colloidal gold particles than non-treated patients, without statistical significance.

[The role of the hepatitis B, C and D viruses in the etiology of chronic hepatopathies in Cluj].

OBJECTIVE: We studied the prevalence of viral hepatitis B, C and D markers in chronic hepatopathies from Cluj. MATERIAL AND METHODS: Sera of 297 patients with chronic hepatopathies (236 adults and 61 children) have been tested for viral hepatitis markers: HBsAg, anti-HBc, anti-HBs, HBeAg, anti-HBe, anti-HDV, anti-HCV, by automated ELISA. RESULTS: HBV infection markers in 32% (adults) and 4.9% (children), and HDV infection markers in 11.8% (adults) and 26.3% (children). Double (HBV and HCV) and triple infection (HBV, HDV and HCV) were observed in 28.4% (adults), 4.9% (children), and 3.4% (adults), 0% (children), respectively. CONCLUSIONS: Hepatitis virus infection markers, especially HBV and HCV play an important role in the determinism of chronic hepatopathies from Cluj area, both in children and adults.
