OBJECTIVE To analyze the status of concomitant or combined infection in patients presented with hepatitis B for investigation of the nosocomial infection control. METHODS We determined the serum virus marker of hepatitis A,C,D,E and G from 786 cases infected with hepatitis B virus. RESULTS Double and multiple infections accompanied by hepatitis B were found to be 16.67%(131/786) and 1.78%(14/786),respectively,especially with hepatitis C which amounted to 45.52%(66/145) of those with concomitant infections(double or multiple). CONCLUSIONS It is commonness that the patient of hepatitis B to preexist other kinds of hepatitis virus infections.We determine other hepatitis markers in patients of hepatitis B to be probative for nosocomial infection.

Objective To study the function of the X\|zone cells in the 5 days old male mouse adrenal gland and the relationship between the function and the sexual differentiation. Methods The technique of in situ RP\|PCR was used to detect the expression of type Ⅰ and Ⅲ 17? HSD mRNA. Results In the cells of X\|zone which located in the interface between adrenal crotex and medulla, there were expressions of type Ⅰ and Ⅲ 17? HSD.Conclusion\ The X\|zone cells of adrenal gland in immature mouse could synthesize androgen, enhanced the male sexual differentiation together with the androgen synthesized from the testis.\;[

Objective To study the regulation role on molecular level of hCG on P450scc,P450c17 and 3?HSD in adult mouse Leydig cells. Methods Leydig cells of adult mice were cultured in vitro for 1 and 8 hours with or without hCG,then P450scc,P450c17 and I,VI total 3?HSD mRNA levels were measured respectively by the semi quantitative RT PCR as well as Scal restriction endonuclease incised methods.Meanwhile,the testosterone contents were measured in two groups. Results 1.In stimulated group Leydig cells cultured for 1 and 8 hours with hCG,the testosterone contents were higher significantly than those in control groups(1 hour P 0.05),but the ratio of type VI/I 3?HSD mRNA gradually increased. Conclusion hCG can stimulate the transcription of P450scc,P450c17 and type VI 3?HSD in adult mouse Leydig cells.
