Susceptibility to Vaginal Candidiasis under Different Conditions in Mice / 华中科技大学学报（医学）（英德文版）

In order to study the susceptibility of murine vaginal mucosa to Candida albicans under different conditions, vaginal lavage fluid and vaginal tissue of mice were observed and compared be tween murine models with normal immune system (estrogen-treated mice) and immunosuppressed murine model, and between primary infection model of vaginal candidiasis and secondary infection one. The average level of colony forming unit (CFU) from the immuosuppressed group was higher than that from estrogen-treated group at each time point and the peak time was delayed. The differences between the two groups were statistically significant (P＜0.05) from the fourth day after in oculation. A significant difference existed in the average level of CFU between the control group and the estrogen-treated group (P＜0.05), and between the control group and the immuosuppressed group (P＜0.01). It was concluded that the vaginal mucosa from the immunosuppressed mice is more susceptible to Candida albicans and no difference is found in susceptibility between mice with primary infection and secondary infection.

The expression of toll-like receptor 2 and 4 mRNA in local tissues of model of oropharyngeal candidiasis in mice / 华中科技大学学报（医学）（英德文版）

To investigate the expression of Toll-like receptor (TLR) 2 and 4 mRNA in local tissues of model of oropharyngeal candidiasis in mice and to explore the potential role of TLR2 and TLR4 in earlier period of immune response, a murine model of oropharyngeal candidiasis inoculated by cotton wool balls saturated with Candida albicans was established. Mice were sacrificed at the indicated time points and the oropharyngeal tissues were excised. The expression of TLR2 and TLR4 mRNA was detected by RT-PCR. The results showed that low level of TLR2/4 mRNA could be detected in oropharyngeal tissues, but they were markedly up-regulated 6 h after inoculation, peaking after 12-24 h. Tissue TLR4 mRNA was gradually down-regulated 24-48 h, while TLR2 mRNA levels remained high up to the 72nd h. These data suggested that oropharyngeal infection of Candida albicans could result in up-regulation of TLR2/4 mRNA expression in local tissues, which might play important roles in earlier period of immune response.

Experiment of turning scleral flap of self-body over drainage in trabeculectomy of glaucoma / 眼科新进展

Objective　To investigate the effect of turning scleral flap of self-body over drainage in trabeculectomy.Methods　The surgery was performed on one eye of a rabbit while　the other eye of the same rabbit was conducted with the routine trabeculectomy as the control group. The filtering bleb, intraocular pressure and pathology were observed. Results　The intraocular pressure in the experimental eye was much lower than that in the control group 3～12 weeks after the operations (P＜0.05).As it was within 2 weeks after the surgeries, but there was no significant filtering difference (P＞0.05).The rate of eyes with functional bleb in the experimental group was significantly higher than that in the control group at the postoperative 2～7 weeks .Conclusion　This study suggests the turning of self-body over drainage surgery can help to maintain filtering function for a long time and to prevent complication after filtering surgery.
