RESUMO

OBJECTIVE:To study the h ypoglycemic effect of Hordeum vulgare polysaccharide(HVP)on diabetes mellitus model mice and its mechanism. METHODS :The mice were given intraperitoneal injection of streptozotocin (120 mg/kg)to induce diabetes mellitus model. After modeling ,the mice were randomly divided into model group ,metformin group (positive control , 200 mg/kg),HVP high-dose ,medium-dose and low-dose groups (300,150 and 75 mg/kg),with 10 mice in each group. Blank control group was established additionally. Administration groups were given relevant medicine intragastrically ;blank control group and model group were given constant volume of water intragastrically ,once a day ,for consecutive 30 days. The levels of fasting blood glucose (FBG)were determined after 10,20,30 days of administration. After last FBG test ,mice were intraperitoneally injected with 10% glucose solution (2 g/kg),then the area under the glucose tolerance (GTT)curve was measured at 30 and 120 min after injection. The serum levels of insulin ,the content of superoxide dismutase (SOD),glutathione peroxidase (GSH-Px), malondialdehyde(MDA)in liver tissue were detected. Pancreatic morphology of mice were detected by HE staining. RESULTS : Compared with blank control group ,the FBG ,area under GTT curve and MDA contnet in liver tissue were increased significantly in model group (P<0.01),while serum levels of insulin ,SOD and GSH-Px contents in liver tissue were decreased significantly (P<0.01);the pancreatic tissue was seriously damaged with incomplete morphology and obvious vacuoles.

CONLUSIONS :HVP can reduce the level of blood glucose in diabetic model mice ,increase insulin level and relieve pancreatic injury. The mechanism may be related to its antioxidation.

RESUMO

Objective To detect the changes in protein profile of rats'lung inhaled radon using two- dimensional electrophoresis(2-DE)and MS.Methods Male Wistar rats were exposed to radon with the cumulative dose up to 100,200 and 400 working level months(WLM).The total proteins of rats'lung were extracted and isolated by 2-DE.The different protein expressions were analyzed with ImageMaster 2D Platinum software and obviously altered proteins were digested by trypsin and identified by MALDI-TOF-MS.Resuits Comparison of the 2-DE images between the control and radon-exposed groups indicated 14 up-regulated and 9 down-regulated protein spots,15 of which were identified by MALDI-TOF or MALDI-TOF/TOF MS.Conclusions The 2-DE image of radon groups'lung has changed,and the lung damage effect of radon is related to some proteins.

RESUMO

Objective To study the antioxidation and immuno-regulation effects of the active fraction in Jiawei Zhisou Powder.Methods Hypersensitive asthma mice were established by the miscible liquids of ovalbumin(OA)and Al(OH)3.The influences of the powder on the contents of SOD and MDA in the serum and lung tissue of mice were observed and the contents of IL-4 and IFN-?in supernatant of mouse spleen cells cultured in vitro were measured by enzyme-linked immunosorbent assay.And Jiawei Zhisou Powder and dexamethasone were administered to normal mice respectively,then the immune organs weight were measured and the spleen and thymus indexes of mice were calculated.Results Compared with the normal group,the contents of SOD and IFN-?were significantly decreased,while MDA and IL-4 contents were obviously enhanced in asthma group(P
