ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medical herbs have been used in China for a long time to treat different diseases. Based on traditional Chinese medicine (TCM) principle, Chaihuang-Yishen granule (CHYS) was developed and has been employed clinically to treat chronic kidney disease including diabetic nephropathy (DN). The present study was(More)
Proteinuria is the hallmark of chronic kidney disease. Podocyte damage underlies the formation of proteinuria, and vascular endothelial growth factor (VEGF) functions as an autocrine/paracrine regulator. Yi Qi Qing Re Gao (YQQRG) has been used to treat proteinuria for more than two decades. The objective of this study was to investigate the protective(More)
Quinoid dihydropteridine reductase (QDPR) is an enzyme involved in the metabolic pathway of tetrahydrobiopterin (BH4). BH4 is an essential cofactor of nitric oxide synthase (NOS) and can catalyze arginine to citrulline to release nitric oxide. Point mutations of QDPR have been found in the renal cortex of spontaneous Otsuka Long Evans Tokushima Fatty(More)
OBJECTIVE To study the anticonvulsive action of scorpion alcoholic extraction (SAE) on phenytoin-resistant convulsive rats made by direct cortical electrical stimulation in order to investigate the mechanism of antagonizing drug-resistance of SAE. METHOD Using the method of implanting microelectrodes in the cortical motor area of the brains of rats where(More)
Dihydropteridine reductase (QDPR) plays an important role in the recycling of BH4 and is closely related to oxidative stress. We have previously reported that the overexpression of QDPR in human kidney HEK293T cells significantly protected against oxidative stress, and these beneficial effects were abolished by A278C mutation. To evaluate the effect of(More)
