ABSTRACT
OBJECTIVE: To establish an animal model of alcoholic fatty liver (AFL) and to observe the prevention and treatment with New Qinggan Decoction (NQGD). METHODS: Female SD rats were exposed to the mixture of white spirit and corn oil continuously for up to 6 weeks via an intragastric feeding protocol. The pathologic alteration of the liver and the changes of serum lipid were observed, and the effect of NQGD for preventing and treating AFL was studied. RESULTS: Wide hepatic steatosis was induced in model group rats. Serum triglyceride (TG) and total cholesterol (TC) of the model group were higher than those of the normal group (P<0.01). Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of the model group were higher than those of the normal group (P<0.05). In NQGD group, hepatic steatosis was milder than that in the model group, and serum TG, TC, AST, ALT descended significantly as compared with the model group (P<0.01). CONCLUSION: AFL model of rats established by feeding the mixture of white spirit and corn oil is similar to the episode of the human AFL, and is easy to intervene with medicine. NQGD can prevent the occurrence of AFL in this model.
ABSTRACT
Objective To better understand the regulation of the soluble receptor of vascular endothelial growth factor (VEGF), s-VEGFR-1 (or soluble fms-like tyrosine kinase, SFlt-1), in angiogenetic process in endometriosis. Methods Levels of free VEGF and s-VEGFR-1 were measured by enzyme-linked immunosorbent assay (ELISA) in peritoneal fluid from 28 subjects with surgically confirmed endometriosis, and 10 controls with no clinical evidence of the disease and other diseases. Meanwhile, we calculated a VEGF activity index by means of the ratio VEGF/s-VEGFR-1. Results We found higher VEGF concentration in endometriotic lesions than controls (P0.05). VEGF activity index in controls, stage Ⅰ-Ⅱ and stages Ⅲ-Ⅳ of endometriosis was 0.310, 0.276 and 0.273, respectively. VEGF and s-VEGFR-1 concentration were also higher in proliferative phase than in secretory phase in endometriotic lesions (P
ABSTRACT
Objective To study the effect and the mechanism of Tongxieyaofang (TXYF) on rat model of irritable bowel syndrome (IBS). Methods Model rats of IBS which were prepared by chronic stimulation in colon were randomly divided into groups: the normal control group (Group A), the model control group (Group B), the positive control group (Group C), the low dosage of TXYF group (Group D), the high dosage of TXYF group (Group E). Different treatments were given to every groups by ig administration for one month. The capability limens of the sacculus that caused abdomen-uplifting and back-arching and the times of contract of abdomen muscle in rats under different dilatations were observed. The levels of 5-hydroxytryptamine (5-HT), substance P (SP), and calcitonin gene related peptide (CGRP) were evaluated. Results Compared with the Group B, the TXYF could effectively improve the index of the behavior and electrophysiology, it also could lower the levels of 5-HT and SP, and increase the levels of CGRP of rat model of IBS with certain dose-effect relationship. Conclusion TXYF could lower the levels of 5-HT in serum and SP in plasma, and increase CGRP level of model rats of IBS, especially in high dosage. The mechanism of TXYF may be increasing the pain threshold of bowel, eliminating hypersusceptibility of bowel, and decreasing excitability of nerve cells by decreasing the 5-HT and SP levels in IBS rats.
