[Experimental study of the protective effects of astragalus and salvia miltiorrhiza bunge on glycerol induced acute renal failure in rabbits].
摘要
The astragalus and salvia miltiorrhiza bunge alcohol extracts were used in preventive treatment of glycerol induced acute renal failure (ARF) in rabbits. The experimental rabbits were divided: astragalus group (AB), salvia miltiorrhia bunge group (SM), two extracts mixture group (ABSM), and normol saline control group (C). The extracts, mixtures and normol saline were administrated before and after the induced ARF. The counts of Na, K, creatinine in urine and blood and urinary AAP, NAG were determinated during 24-14 days periodically in all 4 groups, and the renal tissues were taken from same periods for pathomorphological studies by microscopy and transmission electromicroscopy. The damage of the glycerol induced ARF was not only in the convolute tubules but also in the glomerulus. The glomerulor filtration rate reduced abruptly, and oligouria or auria developed. The study of renal functions and renal morphogy showed that the AB and ABSM groups were damaged more lesser and promptely repaired than the SM and C groups in the early stage. No glomerular sclerosis was noted in the AB, ABSM groups in later stage, but it occurred sporadically or diffusely in the SM, C groups. Therefore, astragalus is an ideal protective drug of traditional chinese medicine for ARF.
