Aim To prepare and identify monodonal sntibody (Mab) specific for Toaoplasma gondii tachyzoites. Method The Mab specific for Taxoplasma gondii tachyrzoite were prepared via bybridoma technique. Indirect ELISA was used to determine the activity of the Mab. Agarose double immuodiffusion test was performed to confirm subclass and SDS-PAGE & western blot were used to analysis rolecular weight of the antigen (s) recognized by the Mab. IFA was used to identify the epitope of Taxoplasma gondii tachyzoites. The protection and specificity of the Mab were snalysed at same time. The Mab was tesed in Mab-ELISA method to detect Taxoplasma gondii antigen. Results A Msb F7C8H12 specific for T. gondii was produced. It belongs to IgG1 subclass. Moleculsr weight of the sntigens recognized by the Mab was 16.5 and 24 kDa. IFA did not show fiuorescence in intact tachyzoite.Inhibition test showed that the inhibition rate was 50% when the concetration of the antigen was 40μg/ml.Afterthe RH strain tachyzoites were incubated with Mab ascites, mice were inected with the tachyzoites through peritoneum. The results showed that the mean dead time of mice were not delayed. T. gondii antigen mixed with PBS snd normal human serum was detected by Mab-ELISA, the sensitvity was 0.78 yg/ml and 1.5μg/ml respectively. When mice were infected with T. gondiiRH strain tachyzoites, 103/mouse p.i., circulating antigen could be detectedin 6 day and 8 day. Conchusion The Mab (F7C8H12) to T. gomdii tachyzoites is an excellent probe for studying T. gondii snd toxoplasmosis.

Objective To discuss whether mild hyperuricemia can lead to kidney damage and the protection of decreased uric acid,through observing that hyperuricemia did damage to glomerulus endothelial function and cell proliferation of vascular smooth muscle in rats. Methods Fifty-four male SD rats were divided into four groups,the control group,model group (Oxonate),allopurinol group and Oxonate+allopurinol group.Rats were administered on a low sodium diet and their systolic blood pressure (SBP) were measured each 10 days.ELISA was used to detect rat plasma markers of endothelial function damage [nitric oxide (NO),type-1 plasminogen activator inhibitor (PAI-1),endothelin 1 (ET-1)] and cell proliferation of vascular smooth muscle[plateletderived growth factor (PDGF),cycloxygenase 2 (COX2),monocyte chemotactic protein-1 (MCP-1)],and the markers of inflammatory reaction[interleukin-18 (IL-18),tumor necrosis factor α(TNF-α)].PDGF and nitric oxide synthase (NOS) levels of rats were detected by immunohistochemical method.Renal tissue pathology of rats was observed. Results Compared to the control group,the plasmic concentration of COX2,ET-1,IL-18,PAI-1,PDGF,TNF-o,MCP-1 increased,and NO decreased significantly in rats of model group (all P<0.05),expression of NOS significantly reduced and PDGF increased (all P<0.05).Under light microscope,vascular wall thickening,intimal proliferation and lumen slight stricture without uric acid crystals in renal tissue were found in model group,which were obviously improved by using allopurinol. Conclusion Mild hyperuricemia can do damage to endothelial function of glomerulus and lead to vascular cell proliferation,which can be improved through decreasing uric acid.
