研究目的是建立印度獐牙菜含量测定方法,评价预防肝损伤药理活性。方法采用獐牙菜苦苷、龙胆苦苷、獐牙菜苷、芒果苷和异荭草苷为指标成分,建立HPLC含量测定外标法。选择芒果苷作为内标,利用各成分的峰面积和浓度,计算各指标成分的相对校正因子,建立一测多评法,以两种方法测量五种指标成分的含量,并进行比较。以印度獐牙菜75%乙醇提取物预防CCl_4致小鼠急性肝损伤,评价其药理活性。结果是HPLC同时测定五种指标成分含量方法学稳定,专属性强,五种指标成分的含量测定范围分别为0.05～0.75μg(r=0.9997),0.07～1.08μg(r=0.9997),0.01～0.122μg(r=0.9997),0.05～0.76μg(r=0.9998)和0.08～1.21μg(r=0.9997)。一测多评法计算得到的五种指标成分含量比外标法得到的含量略低,但均在1.0%的范围之内。印度獐牙菜75%醇提物2.0 g/kg给药剂量能显著预防小鼠CCl_4导致的急性肝损伤。因而印度獐牙菜具有很明显的预防急性肝损伤的药理活性。所建立的印度獐牙菜定量测定方法(外标法、一测多评法)简单准确,为印度獐牙菜指标成分含量测定提供了检测方法。 相似文献

Diabetes mellitus (DM) is one of the most prevalent diseases in the world, which is strongly associated with liver dysfunction. Hyperglycemia, through an oxidative stress pathway, damages various tissues. Herbal medicine is a good candidate to ameliorate hyperglycemia and oxidative stress. In this study, the effects of aqueous Allium sativum (garlic) extract (AGE) on gene expression of inducible nitric oxide synthases (iNOS) and production of nitric oxide (NO) were evaluated in the liver tissue of diabetic rats. Four groups of rats contained normal control rats, garlic control rats (AGE), Streptozotocin (STZ) + nicotinamide-induced diabetic rats (DM), and diabetic rats treated with garlic (DM + AGE). Glucose levels and liver enzymes activities were determined by colorimetric assay in the serum. Gene expression of iNOS by real-time PCR, NO levels by Griess method, oxidative stress parameters by spectrophotometric method and histopathological examination by hematoxylin and eosin staining method were evaluated in the liver tissues. Glucose levels, activities of liver enzymes, oxidative stress markers, iNOS gene expression, and NO production increased significantly in diabetic rats in comparison with control rats, whereas after oral administration of garlic, these parameters decreased significantly, close to the normal levels. Hence, the beneficial effects of garlic on the liver injury of diabetes could be included in the hypoglycaemic and antioxidant properties of garlic via a decrease in gene expression of iNOS and subsequent NO production. 相似文献

Adenosine deaminase and protein tyrosine phosphatase activities in liver and peritoneal macrophages were estimated in control,
streptozotocin induced diabetes and insulin treated diabetic groups of Swiss albino mice. Both the enzyme levels were elevated
while glycogen content decreased in the liver of diabetic group of animals as compared to controls, while in insulin treated
group, they were comparable to control levels. In macrophages also, both adenosine deaminase which plays an important role
in their maturation and protein tyrosine phosphatase enzyme involved in their activation were high in diabetic group, whereas
in insulin treated diabetic group, the values were comparable to control levels. *** DIRECT SUPPORT *** A00FN011 00003 相似文献

Anabasis articulata (Forssk) Moq. (Chenopodiaceae) is an herb, grows in Egypt, and used in folk medicine to treat diabetes, fever, and kidney infections. The protective and therapeutic effects of the ethanol extract of A. articulata aerial parts were evaluated against dimethylnitrosamine (DMN)-induced liver fibrosis, compared with the standard drug, silymarin. Hepatic hydroxyproline content, serum transforming growth factor-β1 (TGF-β1), interleukin 10 (IL-10) and fructosamine were measured as liver fibrosis markers. Hepatic malondialdehyde (MDA), nitric oxide (NO), catalase (CAT), glutathione reductase (GR) and glutathione content (GSH) were measured as oxidant/antioxidant markers. Parallel histopathological investigations were also performed. Protective and therapeutic administration of A. articulata (100 mg/kg daily for 4 weeks), markedly prevented DMN-induced loss in body and liver weights. The extract significantly inhibited the elevation of hepatic hydroxyproline, NO and MDA (P < 0.05), as well as serum fructosamine, and TGF-β1 (P < 0.05) induced by DMN while it restored IL-10 to normal level in both protective and therapeutic groups. Furthermore, A. articulata prevented the depletion in CAT, GR, and GSH levels (P ≤ 0.05). In addition, oral administration of A. articulata extract and silymarin to both protective and therapeutic groups reduced the increase in liver function enzyme activities; alanine and aspartate amintransferases, gamma-glutamyl transferase in addition to alkaline phosphatase, and caused significant increase in serum albumin concentration as compared to DMN group. These data corresponded closely with those obtained for the drug silymarin. Histopathological studies confirmed the biochemical data and revealed remarkable improvement in liver architecture. Thus, it could be concluded that, A. articulata extract exhibited in vivo hepatoprotective and therapeutic effects against DMN-induced liver injury and may act as a useful agent in controlling the progression of hepatic fibrosis through reduction of oxidative stress and improving liver function. 相似文献

Red-cell glutathione (GSH) contents and enzyme activities of glutathione peroxidase (GSH-Px) as well as glutathione reductase (GSSG-R) were assayed in 30 normal subjects, 60 cirrhotic patients and 60 cancer patients. The mean GSH level and GSSG-R activity studied showed increased values in all diseased groups compared to normal values with significant elevations only in liver metastases group. Reduced enzyme activity of GSH-Px has been noted in both the cirrhotic groups but the decrease was significant only in alcoholic cirrhotic group. Decreased red-cell GSH-Px activities below the normal range were found in all the cancer patients with remarkable reduction in liver metastases than in hepatocellular carcinoma. 相似文献
