RESUMO
Aim To observe effects of compound dialysate of Chinese herbs and Western medicines on small intestinal mucosa ultrafiltrative function in dogs. Methods Twenty Beagle dogs were divided into 4 groups: NS, control (CG), lower ligustrazine dose (LLDG) and higher ligustrazine dose group (HLDG). According to the arteriovenous region of small intestine mesentery to make three isolation loops for comparative study, they were respectively jejunum loop (JL), jejunoileum loop (JIL) and ileum loop(IL), and input hypersonic sample solution through vein after blocking the renal arteries to make the man-made renal failure models such as electrolytic disorder, azotemia etc. Meanwhile, the dialysate was perfused from the inlet of these isolation loops, respectively.Finally, these secretion of small intestine loops and blood samples which arteria and venae of the small intestine mesentery every 30 minutes were collected to determine the density of K+, Na+, Cl-, UN, CR, UA and the clearance and filtration rate in each group were calculated. Results The clearance rate and filtration rate in LLDG were remarkablely higher than that in the LHDG、the CG and the NS (P
