[Protective effect of prostaglandin E on hepatocytes and its value of early treatment of severe viral hepatitis].

An animal model of hepatocytic necrosis was established with injection of D-galactosamine into peritoneal cavity. Examination at regular intervals after injection showed that the level of increased serum TB, ALT and GST and the degree of histological changes in the liver were less marked in PGE-treated animals (n = 34) than those in PGE-untreated animals (n = 29), suggesting that PGE has definite protective effect for experimental hepatocytic necrosis. According to severity of the condition hepatic failure was divided into early stage, typical stage and late stage. A treatment group of 55 cases received PGE1 therapy and a control group basic support therapy only. The results showed that difference of the total effective rate was not significant between the two groups, but in the early stage of hepatic failure, the effective rate in the treatment group was markedly higher than that in the control group. In addition, incidence of hepato-renal syndrome was lower in the treatment group. We are of the opinion that division of severe viral hepatitis into three stages for evaluation of therapeutic effect is rational and useful and early use of PGE1 may show certain efficacy.

New method to measure minisatellite variant repeat variation in population genetic studies.

The classical analysis of minisatellite variant repeat (MVR) variation using modular structures is limited by the lack of knowledge of the mutational process involved in the evolution of most of the minisatellites. In this study a new method to measure MVR variation and to calculate genetic distances using MVR codes is proposed. The method is based on the statistical similarity of MVR patterns and considers the complete variability of the minisatellite, enabling meaningful comparisons of closely related populations. As an example, the method has been applied to analyze variation in MSY1 (DYF155S1) in five sets of data from European and North African populations.
