Objective: To observe the effect of Rosiglitazone (RGTZ) on oxygen free radical and biochemical parameters of aged rats, so as to establish a basis for anti-aging study. Methods: The 24-month-old naturally aged SD rats were randomly divided into the control group (CONT), the RGTZ group and the caloric restriction group(CR). The RGTZ group was given intragastric administration of RGTZ (4 mg · kg-1 · d-1) and the CR group was given 60% of the diet that of the CONT group. The rats were killed 12 weeks later and the serum malondialdehyde(MDA) content, superoxide dismutase(SOD) activity and the blood biochemistry parameters were examined. Results: The blood glucose (GLU), aspartate transaminase (AST), alamine transaminase(ALT), serum creatinine (SCr), and blood urea nitrogen (BUN) were within the normal range in all groups. Compared with the CONT group, blood cholesterol (CH) in RGTZ group was lower, but with no significant difference. The serum triglyceride(TG) of both RGTZ and CONT groups decreased markedly than those in the CONT group(P<0.05). The activities of SOD and MDA were improved in RGTZ and CR group compared with the control group. Conclusion: RGTZ can regulate the lipid metabolism and attenuate the oxidative damage in aged rats, indicating its anti-aging effect.

Objective: To investigate the expression of peroxisome proliferator-activate receptor γ(PPARγ) in the kidneys of rats at different ages, so as to study the possible association of PPARγ expression with oxidative stress in the aging process. Methods: Rat aging model was established using 3-, 12-, and 24-month old rats. Western blotting was used to determining the protein expression of PPARγ. The changes anti-oxidative ability of renal tissue were studied by determining the activities of superoxidedismutase(SOD) and glutatio-neperoxidase(GSH-PX). Results: Western blotting assay showed that the renal expression of PPARγ protein decreased with the aging of rats,with that of 3-month group significantly higher than that of the 24-month group(P<0.01). The activities of SOD and GSH-PX deceased with the aging of rats(P<0.01). Both the SOD activities were positively correlated with the expression of PPARγ protein(r=0.90, r=0.89, P<0.01) Conclusion: Renal PPARγ has a decreasing tendency during the aging process of rats, which is correlated with the down-regulation of anti-oxidative ability of renal tissue.

Objective To know the drinking water quality in villages of Tongzhou District,Beijing and provide the basic data for government. Methods 623 wells in 455 villages were sampled in 2004 and the water samples were tested with the national standard methods. Results 166 of 623 water samples were up to standard,the qualification rate was 26.65%. The drinking water quality of all villages was different,in Maqiao(58.62%) and Liyuan(76.92%) it was better than that in Xiji,Huoxian,Zhangwan,Songzhuang. The qualification rate in Xiji was only 10.26%. In the present investigation,24 water quality parameters were tested and 14 parameters exceeded the limit,such as NH3-N,iron,total bacterial count,coliform group,fluoride and arsenic. Some sanitary problems were also found. Conclusion The ground water in Tongzhou has been contaminated,especially the shallow layer ground water,more attention must be paid to improvement of drinking water quality in these villages.

Objective To investigate the effect of HO-1 on acute rejection after orthotopic liver transplantation (OLT) in rats. Methods Taking dark agouti (DA) rats as donors and Lewis rats as recipients, OLT was performed. Before OLT, the DA rats and Lewis rats were matched in pairs, and divided into control group, ZnPP group and CoPP group, the paired rats of which intraperitoneally received normal saline, 20 mg/kg ZnPP and 5 mg/kg CoPP respectively 24 h before OLT. Ten pairs of rats were in each group. On day 3 or 7 after OLT, recipient rats were killed, then blood sample and liver specimen were collected. Plasm levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), albumin (ALB) were measured; HE staining and MPO staining were performed; The expression of HO-1 was detected by the fluorence real time RT-PCR. Results On day 3 and 7 after OLT, AST, ALT and TBIL showed significant statistical significance among the three groups; ALB was highest in CoPP group, then in control group, lowest in ZnPP group. On day 3 after OLT, control group had acute rejection of degree one to degree two, ZnPP group had acute rejection of degree two; CoPP group mainly had acute rejection of degree one; On day 7 after OLT, control group mainly had acute rejection of degree two; ZnPP group had acute rejection of degree two to degree three; CoPP group had acute rejection of degree one to two. The expression of HO-1 was highest in CoPP group, then control group, and lowest in ZnPP group. Conclusion The expression of HO-1 in OLT with acute rejection in rats can palliate the acute rejection.
