Objective To explore the regularity of dynamic morphologic changes of the sinoatrial node (SAN) cells of rabbits after the constitution was damaged by formaldehyde wet dressing. Methods Sixty rabbits were randomly divided into 6 groups (n=10 in each group): the control group and 5 experimental groups observed at 2 h, 1, 2, 3, and 4 weeks respectively after the operation. The SAN constitution of rabbits was damaged by 20% formaldehyde wet dressing. The constitutions of SAN were cut quickly at 2 h after wet dressing in the control group and at the corresponding time points in other experimental groups respectively. The specimens were made for light microscopical and electron microscopical observations. The apoptosis of SAN cells was detected by TUNEL method. Results Compared with those in the control group, SAN cells in all experimental groups were damaged at various degrees observed by light microscopy and electron microscopy. Distinct cell tumefaction, soak of grain cells, cytoclasis, hyperplasia of collagen fibers, and other pathological changes were detected. Electron microscopical observation showed distinct pathological changes of the super-micro construction of cells. Apoptosis was not detected in the control group, but various degrees of apoptosis in all experiment groups. The apoptotic rates in all experimental groups were significant as compared with that in the control group (P

Objective To determine the levels of anti-Toxoplasma gondii antibody (ATAb) and antisperm antibody (AsAb) in serum samples and interferon-?(IFN-?) in supernatants of peripheral blood cell culture in females with infertility, and to analyze their correlation. Methods ELISA was applied to determine and compare the ATAb and AsAb in serum samples of 182 women with infertility and those of 94 women with normal pregnant history. The level of IFN-? in supernatants of peripheral blood cell culture was also measured and compared by ELISA. Results The positive rates of serum ATAb and AsAb in the cases of infertility were 15.38% and 18.13% respectively, which were significantly higher than those of women with normal pregnant history( 6.38% and 5.32%). The supernatant IFN-? level in infertile women was significantly higher than that of women with normal pregnant history (0.970?0.493) ?g/L vs (0.531?0.274) ?g/L(P

Objective To explore the influence of Toxoplasma tachyzoites infection on motility of human spermatozoa in vitro, and explain its possible mechanism. Methods Semen samples obtained from 10 healthy volunteers by masturbation were prepared by the swim-up technique. The samples were then inoculated at 37 ℃ with different concentrations of live Toxoplasma tachyzoites varying among 1?103/ml (Group A), 1?104/ml (Group B), 1?105/ml (Group C), 1?106/ml (Group D), 1?107/ml (Group E) and Group F containing Ham’s F-10 only as the negative control. Motion parameters were analysed by Computer-aided sperm analyzer(CASA) in 0 hour, 1 hour, 2 hours, 4 hours respectively. Modalities of spermatozoa and possible adherence and/or agglutination were observed under the light microscope. Results Distinct adhesion of spermatozoa to Toxoplasma tachyzoites and agglutination were noticed. In all the motion parameters, progressive motility was affected most and dependent upon the incubation time and tachyzoites concentration. Progressive motility showed a significant difference between Group E and the control (P

Objective To explore the relationship between tumor necrosis factor-?(TNF-?)level in the serum of maternal women with intrauterine infection of Toxoplasma gondii and absortion.Methods An examination was carried out on TNF-? in maternal sera and DNA of Toxoplasma gondii in the cervical secretions,and the aborted tissues of the abortion group,and the cervical secretions of the control group by ELISA and PCR,respectively.Results The TNF-? levels increased in the sera of women with intrauterine infection of Toxoplasma before abortion as compared with those of the control group and those of themselves after abortions.There were high TNF-? levels in the sera of prognostication abortion women with Toxoplasma infection before the anti-Toxoplasma treatment as compared with those of the control group and those of themselves after the treatment with azithromycin.Conclusion The results suggest that Toxoplasma gondii infection is an important factor to increase the TNF-? level in maternal serum.

Objective To explore the effect of reducing sub-clinical infections of Toxoplasma gondii in newborn babies with preventive treatment. Methods Forty-four infected pregnant women were treated in different period and their umbilical blood and/or placenta of their newborn babies were tested for IgG, IgM, cAg and DNA of Toxoplasma gondii. Results The positive rate of Toxoplasma DNA in umbilical blood was 37.8%(14/37). The lowest rate was found in the preventive treatment group with a significant difference compared with the group of general treatment. Conclusion Preventive treatment can reduce sub-clinical infection rate of newborn babies effectively.

B7-H1, a recently described member of the B7 family of costimulatory molecules, is thought to be involved in tumor immune escape by inducing T-cell apoptosis. In order to investigate the relationship between B7-H1 and immune escape of bladder cancer, B7-H1 expression in 50 cases of bladder cancer was detected by using immunohistochemical method. Survival curves were constructed using the Kaplan-Meier method and independent prognostic factors were evaluated using the Cox regression model. Our results showed that the positive rate of B7-H1 immunostaining in normal bladder tissue and bladder cancer was 0 and 72% respectively. The expression of B7-H1 was strongly associated with the pathological grade, clinical stage and recurrence (P<0.05). The survival rate was significantly lower in patients with B7-H1 positive group than in those with B7-H1 negative group and multi-variable analysis revealed that B7-H1 could be regarded as an independent factor in evaluating the prognosis of bladder cancer. It is concluded that the expression of B7-H1 is strongly associated with neoplastic progression and prognosis of bladder cancer. The manipulation of B7-H1 may become a beneficial target for immunotherapy in human bladder cancer.
