曲普瑞林对雷公藤多苷诱导的小鼠卵巢细胞损伤具有保护作用 [2]。

曲普瑞林对雷公藤引起的雌性小鼠卵巢功能损害具有保护作用[2]。

For qualified, healthy SD female mice, the vaginal exfoliated cell method was used to select 30 mice with normal estrous cycle as test animals, which were randomly divided into 3 groups of 10 mice each: • Group A: blank control group, where 0.35 mL of saline was administered to the stomach once daily for 11 weeks; • Group B: tripterygium glycoside group, where 0.35 mL of tripterygium glycoside solution was administered to the stomach from the 8th day; once a day for 10 weeks; • Group C: triptolide + triptorelin group: 0.1 mg/kg daily subcutaneous injection of triptorelin injection; once a day; continuous injection for 11 weeks; from the 8th day, the triptolide solution was administered to the stomach 0.35 mL, once daily for 10 weeks. From the first day of the experiment, the general conditions of the mice were observed and recorded, including energy, activity, hair, food intake, water intake, stomach appetite, second stool, etc. The mice were weighed once a week to observe changes in body weight. The vagina exfoliation cell method, simple to operate, was used to observe the estrous cycle. After 11 weeks of treatment, the drug was stopped for 3 weeks and all mice were sacrificed. The ovaries were then obtained by laparotomy, and the ovarian wet weight was measured using an electronic analytical balance. The ovarian index was calculated by ovarian wet weight (mg) / mouse weight (g) × 100%. After weighing, the ovaries were fixed in a 4% paraformaldehyde solution for 3 days, and were routinely dehydrated, xylene-transparented, wax-impregnated, embedded, sectioned (4 µm), and operated according to the instructions of immunohistochemistry kit. Immunohistochemical average optical density (average optical) analysis method: each slice in each group randomly selected at least three positions with a 200× field of view (FoV) for photographing. When taking pictures, FoV was selected to ensure that the testing tissue fully filled the view. In addition, the background illumination of each photo was kept as consistent as possible. Image-Pro Plus 6.0 software was used to select the same brown-yellow color as the uniform standard for determining the positives of all photos. Each photo was analyzed to obtain the Integrated Optical Density (IOD) and the pixel area (AREA). The average optical density (AO) was obtained by AO = IOD/AREA. (1) The larger the AO value, the higher the positive expression level. [2]

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果，工作液请现配现用！
6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们;
