RESUMEN
The cytoprotective effect of misoprostol co-administered with non-steroidal anti-inflammatory drugs (NSAIDs) was assessed in a double blind, placebo controlled study. Thirty-seven patients with rheumatoid arthritis receiving NSAIDs, having upper gastrointestinal symptoms and endoscopically confirmed gastric and/or duodenal lesions, were randomised to receive either misoprostol 200 micrograms or placebo tablets twice daily for 4 weeks. Of 31 evaluable cases, 13 of 16 (81%) patients receiving misoprostol showed endoscopic improvement as compared to 10 of 15 (67%) receiving placebo (P:NS). A significant decrease in mean (+/- SEM) mucosal lesion score was observed with misoprostol (from 3.38 +/- 0.32 to 1.32 +/- 0.44; P less than 0.001) but no change was seen with placebo (from 2.80 +/- 0.42 to 1.60 +/- 0.53; P:NS). Symptomatic relief was similar in both groups, being 44% and 40% respectively. Two patients complained of diarrhea in each group and one developed menorrhagia with misoprostol. It is concluded that though misoprostol decreased the number of NSAID-induced mucosal lesions, it was unable to relieve gastrointestinal symptoms.

A study of the immunogenicity and safety of 20 micrograms recombinant DNA yeast derived hepatitis B vaccine was conducted in 153 Pakistani adults. All participants were in good physical condition, had negative hepatitis B serological markers (HBsAg, anti-HBs, anti-HBc) and normal ALT. Anti-HBs developed in 33%, 81% and 98% of subjects one month after the first, second and third dose respectively. Minor systemic and local side-effects were observed in 39% of individuals. We conclude that yeast derived hepatitis B vaccine is safe, effective and immunogenic in Pakistani adults.

Postprandial sera of seventy patients with liver disease (hepatitis 30, cirrhosis 19, liver cancer 21) were analysed for total serum bile acids. The mean values observed in hepatitis (169.0 mumol/L), cirrhosis (112.15) and liver cancer (86.44) were significantly higher (p less than 0.001) than in normal (19.45). The frequency of abnormal bile acids was greater than that of the standard liver function tests except for alkaline phosphatase in liver cancer.
