[Inhibition of human immunodeficiency virus reverse transcriptase in vitro by extracts of Chinese medicinal herbs]

Thirty-three chinese medicinal herbs reputed by ancient chinese folklore to have anti-infective properties were extracted. The extracts and their compounds were tested for inhibitory activity against the human immunodeficiency virus RT in vitro. 8 of the 33 extracts were found to be active. Of these, MBAA9045 was studied in greater depth. We found that it was a noncompetitive inhibitor against HIV-RT. The concentration of MBAA9045 reducing HIV-RT activity by 50% (IC50) was 22 mumol/L. Chinese medicinal herbs appear to be a rich source of potentially useful materials for the treatment of human immunodeficiency virus infection.

[Observation of efficacy of different dialytic therapies in renal transplantation preparation]

Fifty-seven cadaveric renal transplantations in fifty-five cases were analysed of them, thirty cases were prepared by continuous ambulatory peritoneal dialysis (CAPD group); twenty-seven transplantations in twenty-five cases were prepared by hemodialysis (HD group). Our data show that there is no significant difference in the survival duration between CAPD group and HD group; that there is also no significant difference in the survival duration between the two groups treated with the same immunosuppressive drugs, and that patients prepared by CAPD have a low risk of peritonitis after transplantation. It is better not to remove the Tenckhoff catheter until the graft function is stable so that it can be used for the transient peritoneal dialysis in the case of the insult of graft function or for the sampling of the peritoneal effusion for diagnosis of suspectable peritonitis after renal transplantation.
