[Primary serologic investigation of HBV-like virus existence in domestic animals and fowls].

Using the reagent kits for detecting human HBV, primary serologic investigation was made in 6 kinds of domestic animals and fowls (total 673) by ELISA, spot hybridization and immuno-electronmicroscopy. The results showed that some sera samples of pigs, rabbits, chicken and geese were HBsAg, HBeAg positive and positive for spot hybridization by using 3(2)P-HBV-DNA probe, which suggested that HBV-like viruses might exist in those domestic animals and fowls. HBV-like virus particles were seen in one pig serum sample which was HBsAg positive. The particles could be divided into three forms in shape, large spherical particle (40-55nm), small spherical particle (20-30nm) and short filament particle. The further studies are needed.

[Treatment of orthostatic dysregulation by the principle of bu-shen yi-qi].

Sixty cases of orthostatic dysregulation was randomly divided into treatment group (TG) and control group (CG), both 30 cases. Traditional Chinese medical herbs were used for TG under the principle of Bu-Shen Yi-Qi, and routine treatments such as oryzanol, vitamin B1 and B6 were applied to CG. After a curable stage of one month, the results showed that 16 of TG and 4 of CG were cured; 8 of TG and 6 of CG improved. The cure rate and the effective rate were significantly better in TG than in CG (P less than 0.01). 43 cases (71.7%) clinically expressed mild anemia. Before and after the treatment, the values of RBC, SI, Hb, SIBC, MCH in 20 cases of TG turned significantly better (P less than 0.01), but 17 cases of CG remained unchanged under the principle. The authors purposefully selected herbs that contain rich trace elements. For example, iron is an important element of Hb and zinc is an element in proteotic nucleicacidase. The quantity of zinc in body is related to many enzyme activities. Since these herbs could increase chronotropic effect of blood vessels and cure anemia, they could be used to cure patients with orthostatic dysregulation.

[A novel method for determining an integrated character in quantitative genetics].

This paper describes a novel method using maximum entropy principle introduced by Shannon to construct a unique integrated character and gives a comparison between this method and multivariate statistics in quantitative genetics. In multivariate genetic analysis multivariate statistics is usually used for a polygenic system of multiple quantitative traits to form several complex character. Genetic analysis can be implemented through treating these correlated elementary traits by using the technique of principal component analysis or canonical correlation. Differing from the multivariate statistics, this paper presents a new method using maximum-entropy principle to obtain a unique integrated character from a set of correlated quantitative traits. This method has the advantages of simple mathematical structure and process, simple and clear results.

[The effects of inherited susceptibility and life style on essential hypertension].

A case-control study of hypertension of 140 pairs indicated that inherited susceptibility and harmful life style were quite important risk factors in increasing the development of hypertension. The effects could be taken place by their interaction. Changing life style could be taken as one of the significant measures for preventing hypertension among population with inherited susceptibility.

The polymorphism of HLA antigens in the Chinese.

Remarkable differences were observed in antigen frequencies (AF), gene frequencies (GF) and haplotype frequencies (HF) when 2441 healthy Chinese individuals representing nine different ethnic groups and living in 14 different geographic locations were examined for the genetic distribution of the various HLA Class I and II markers. A sizable number of individuals of each ethnic group within each of the three major categories of the Chinese population, namely, Hans, Mongols, and Southern minorities, have been studied here, providing useful population statistics for applications such as determination of probabilities of paternity, comparisons for HLA and disease associations, and anthropologic studies.
