普通级与清洁级灰仓鼠脏器重量与脏器系数的比较

目的 测定并比较普通级与清洁级灰仓鼠的主要脏器重量及脏器系数的差异.方法 解剖普通级与清洁级灰仓鼠各40只,使用电子天平共测定12种脏器指标,并计算了脏器系数.结果 清洁级与普通级灰仓鼠雄性之间比较,心、肝、附睾重量有统计学意义（P＜0.01）,脑、肾脏的脏器系数差异有统计学意义（P＜0.01）；清洁级与普通级灰仓鼠雌性之间比较,心脏重量差异统计学意义（P＜0.05）,肾脏脏器系数有统计学意义（P＜0.01）；普通级灰仓鼠雄雌之间脏器系数比较,脾差异统计学意义（P＜0.05）；清洁级灰仓鼠雄雌之间脏器系数比较,心脏差异有统计学意义（P＜0.01）.结论 清洁级与普通级灰仓鼠的脏器重量、脏器系数差异较大.

Comparison on Organ Weight and Coefficient Between Conventional and Clean Cricetulus griseus

Objective To detect and compare the differences in main organ weight and coefficient between conventional and clean Cricetulus griseus. Methods Forty conventional and clean Cricetulus griseus were dissected respectively. Weight of tissues and organs was measured with electronic balance to detect indices of 12 organs, and the organ coefficient were calculated. Results Compared with the conventional and clean male Cricetulus griseus, there was statistical significance in weight of heart, liver and epididymis （P〈0.01）, and in visceral coefficient of brain and kidney （P〈0.01）. Compared with the conventional and clean female Cricetulus griseus ,showed statistical significances in weight of heart and renal coefficient （P〈0.05）. In conventional Cricetulus griseus, spleen coefficient was different between male and female （P〈0.05）. In clean Cricetulus griseus, there was statistical significance in heart coeffi- cient between male and female （P〈0.01）. Conclusions There are obvious differences in weight and coefficient of organs between clean and conventional Cricetulus griseus.
