ABSTRACT
OBJECTIVE To study the effects of cy cloastragenol （CAG） on carbon tetrachloride （CCl4）-induced hepatic fibrosis（HF）and glycolysis in mice. METHODS Male ICR mice were randomly divided into blank group ，model group ，CAG low-dose，medium-dose and high-dose groups （60，120，240 mg/kg），with 6 mice in each group. Except that blank group was given olive oil intraperitoneally ，the mice in other groups were intraperitoneally injected with 10％CCl4-olive oil solution （5 mL/kg） three times a week for 8 weeks to induce HF model. From the 4th week after modeling ，mice in each drug group were given corresponding drug solution intragastrically （10 mL/kg），and mice in blank group and model group were given 0.5％ sodium carboxymethyl cellulose solution intragastrically （10 mL/kg），once a day for 4 weeks. During the experiment ，the body weight of mice were weighted ；after last gastrogavage ，the liver weight was weighted and liver indexes of mice were calculated. The changes of hepatic injury indexes [aspartate aminotransferase （AST）， alanine aminotransferase （ALT）]， related indexes of HF [hematoxylin-eosin （HE）staining score ，Masson and Picrosirius red staining collagen volume fraction ，collagen Ⅰ，α-smooth muscle actin （α-SMA）] and related indexes of glycolysis [lactic acid （LD），hexokinase（HK），phosphofructokinase（PFK）， pyruvate kinase （PK）] were all detected. RESULTS Compared with model group ，the collagen deposition and fibrosis of mice in each drug group were reduced ，and the body weights of mice （except for CAG low-dose group ）were increased to some extent （P＜0.05）. Liver indexes ，serum levels of ALT and AST ，HE staining score of liver histopathology ，Masson and Picrosirius red staining collagen volume fraction ，protein expression of collagen Ⅰ and α-SMA，serum content of LD ，the levels of HK ，PFK and PK in serum and hepatic tissues （except for hepatic tissue of CAG low-dose group ）were all decreased significantly （P＜0.05）. CONCLUSIONS CAG can improve HF in mice induced by CCl 4，and reduce the levels of key enzymes and products of glycolysis.
ABSTRACT
Objective To study the clinical efficacy of superselective uterine arterioembolization in treating uterine myoma. Methods From February to August 2000, 28 cases of uterine myomas were undergone bilateral arterioembolization of tumor feeding vessels. Results The successful rate of embolization catheterization reached 100%.B-mode ultrasound examination revealed the following during 1～6 months after the procedure, with an average shrinkage of 25% in volume for all cases in the first month follow up,complete disappearance of tumor in 8 cases and with an average shrinkage of 68% volumetrically for the other 20 cases, together with conspicuous decrease in volume of menstruation.Conclusions Interventional treatment for uterine myoma is definite effectilve especilally in submucosal uterine myoma.
