目的 探索构建经济实用的白色念珠菌性阴道炎动物模型的最佳成模条件.方法 采用SPF级昆明雌性小鼠,经不同剂量的苯甲酸雌二醇(E2)处理后,小鼠阴道内注入含不同菌量白色念珠菌悬液造模.造模后动态观察小鼠的一般情况及外阴阴道症状,阴道灌洗液菌丝生成情况及菌落计数,并观察白色念珠菌性子宫积液情况及组织病理学情况.结果 随着接种菌量及E2量的增加,阴道炎感染率随之增加,但白色念珠菌性子宫积液率亦增加.J3E2组(接种菌量为5×104个/只,皮下注射E20.025 mg/只),第2天始即出现高水平的菌落数,CFU≥104/ml,第4天菌丝检出率可达80%,并可持续至实验结束,与接种菌量≤5×104个/只及皮下注射E2≤0.025 mg/只的各组菌落数比较差异均有统计学意义(P<0.01或0.05),与接种菌量≥5×104个/只及皮下注射E2≥0.025 mg/只的各组菌落数比较,差异均无统计学意义;且子宫积液率为33.33%,明显低于接种菌量≥5×104及皮下注射E2≥0.025mg/只的各组.感染成功小鼠阴道组织切片PAS染色阴道浅层组织及腔内见大量孢子及菌丝.结论 J3E2组为昆明小鼠白色念珠菌性阴道炎模型最佳成模条件. 相似文献

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 between 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 inoculation. 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. 相似文献

To investigate the expression of vaginal Th1 and Th2 cytokines in rats with experimental vaginal candidiasis under different immune conditions, ICR murine vaginal candidiasis model was established and immno-suppressed murine models of vaginal cadidiasis were established in estrogen-treated mice. Non-estrogen-treated mice were used as controls. The mRNA level of Th1 (IL-2)/Th2 (IL-4, IL-10, TGF-β1) cytokines in murine vaginal tissues was determined by RT-PCR. The cykotine in local tissues was increased to different extent under normal immune condition. IL-2 mRNA was increased during early stage of infection, while IL-10 was increased transiently during late stage of infection. TGF-β1 production was found to be increased persistently. At same time, the expression of IL-2 mRNA was suppressed in immno-suppressed group, and the level of IL-4, IL-10, and TGF-β1 were higher than the normal immunity group to different degree during infection. The high level of IL-2 mRNA during early stage of infection was associated with clearance of mucosal Candidia albicans (C. albicans), and its expression suppressed leading to decreased clearance of mucosal C. albican in immuno-suppression. The over-expression of IL-4 and IL-10 could significantly enhance the susceptibility to C. albicans infection in mice. 相似文献

目的 探讨耳念珠菌在不同条件下的生长特性、代谢特点及体内毒性特征。方法 以白色念珠菌为参照,测定并比较耳念珠菌与白色念珠菌在常规培养条件、不同pH值和不同盐含量下的生长情况;利用微量生化反应管测定两种念珠菌糖醇发酵情况;以四周龄裸鼠为实验动物,用随机数字表法分为3组,耳念珠菌感染组、白色念珠菌感染组和生理盐水对照组,5只/组。耳念珠菌感染组和白色念珠菌感染组取0.3 mL已调至5×109 cfu/mL菌液,对裸鼠进行灌胃处理,建立胃肠道感染模型,对照组用等量生理盐水灌胃,取肝脏、肾脏、肠、粪便和血液等标本,通过真菌培养和组织病理学变化分析耳念珠菌的体内分布和毒性特征。结果 耳念珠菌的对数生长期约为8~24 h,约在24 h后进入生长稳定期,最适生长的pH值范围为5~7,生长模式与白色念珠菌相同;耳念珠菌在浓度为5%和10%的NaCl培养基中生长情况优于白色念珠菌,能发酵葡萄糖、蔗糖、海藻糖和山梨醇;从裸鼠的粪便、血液、肝脏和肾脏组织中分离出耳念珠菌,肝脏载菌量最多为5.7 log10 cfu/g,其可造成肝组织和肠组织病理学改变,但病变程度比白色念珠菌弱。结论 耳念珠菌在弱酸或中性条件下最适宜生长,具有高耐盐性,在免疫抑制状态下感染机体后,存在突破肠屏障入血及随血流播散并导致组织病变的可能。 相似文献

The Effect of Itraconazole on the Vaginal Candidiasis under Different Immunity Conditions in Mice 总被引:1,自引:0,他引:1
To study the effect of itraconazole on the vaginal candidiasis caused by Candida under different immunity conditions, the fungal vaginitis model was established in female ICR mice by in- travaginal inoculation of suspension of C. albicans after the animal had been pretreated with estradiol or dexamethasone. Mice were divided at random into different groups and then treated with itracona- zole or IFN-γ given by gastrogavage. The burden of the fungus in the vaginal lavage fluids in the mice of the different groups was measured dynamically at different time points after the beginning of the drug treatment. The difference in the effect of itraconazole on the vaginal candidiasis between normal immune system group (group A) and control group (group D) was statistically significant (P<0.01). The difference in the efficacy of itraconazole among immunosuppressed group (group E), immuno-regulated group (group F) and the control group (group G) was statistically significant (P<0.01). But on the 5th, 6th, 7th, 9th, 11th day after the inoculation the average level of colony forming unit (CFU) of groups A, E and F showed no statistically significant difference (P>0.05). It is concluded that the efficacy of itraconazole in the treatment of the vaginal candidiasis under different immunity conditions (groups A, E and F) in mice were all good, but there was no difference in the anti-fungal effect of itraconazole among the three groups. 相似文献

目的研究妊娠期妇女阴道念珠菌对克霉唑、咪康唑、制霉菌素的敏感性,为妊娠期念珠菌性外阴阴道炎(VVC)的治疗提供理论依据。方法选取来自628人次妊娠期妇女的阴道念珠菌,参考美国国家临床实验标准化委员会的抗真菌药物敏感实验标准,以微量平板法检测不同菌株对克霉唑、咪康唑和制霉菌素的药物敏感性。结果妊娠期VVC发生率为19.3%,感染的念珠菌存在明显的菌种多样性,白色念珠菌最为多见。对于白色念珠菌,咪康唑的24h最小抑菌浓度(MIC)明显低于制霉菌素(P〈0.01);不同孕期3种药物的48h MIC差异均无统计学意义(P〉0.05);对于非白色念珠菌,咪康唑的24、48h MIC明显低于制霉菌素和克霉唑(P〈0.01),晚孕期克霉唑和制霉菌素的24、48h MIC与早孕期和(或)中孕期差异有统计学意义(P〈0.05)。结论妊娠期阴道白色念珠菌对抗念珠菌药物相对敏感,不同孕期治疗原则大体一致。妊娠期非白色念珠菌性阴道炎的治疗相对困难,普通克霉唑制剂不宜使用,早、中孕期治疗可选制霉菌素制剂,晚孕期可选咪康唑制剂。 相似文献

To compare the therapeutic effects of three different anti-fungal drugs (i.e., terbinafine, fluconazole and intraconazole) in the treatment of experimental vaginitis caused by Candida albicans (C. albicans) in mice, the fungal vaginitis model was established in female ICR mice by intravaginal inoculation of suspension of C. albicans after the animal had been pretreated with estradiol. Mice were divided at random into different groups and then respectively treated with terbinafine, flucona- zole and intraconazole given by gastrogavage. The burden of the fungus in the vaginal lavage fluids in the mice of the different groups was measured dynamically at different time points after the begin- ning of the drug treatment. The fungal burdens in the vaginal lavage fluids taken at different time points from the mice treated with terbinafine were significantly higher than those taken at corre- sponding time points from mice treated with fluconazole or itraconazole (P<0.01). The fungal bur- dens in the vaginal lavage fluids taken from mice 1 week after the beginning of the treatment with terbinafine remained at a relatively high level. A dramatic drop in the fungal burden was noted in the vaginal lavage fluids taken on the 2nd day of the treatment from mice treated with itraconazole or flu- conazole group and the fungal burden on the 3rd day of the treatment in these mice were at a very low level, suggesting that fluconazole or itraconazole were highly effective for the treatment. How- ever, the difference in the therapeutic effect between the two drugs was not significant (P>0.05). Itraconazole or fluconazole, but not terbinafine, is very effective for the treatment of fungal vaginitis caused by C. albicans in mice. 相似文献
