【摘要】 目的：本研究意在了解褐家鼠对环境的生理生态适应情况，为探讨其越冬生态学等问题提供基础资料。方法：称量体重．然后剥皮，剖取五脏，称量鲜重与干重。结果：心、肝、肺、肾的绝对重量或相对重量，分别与体重呈正相关或负相关。结论：相对重量春、冬季高于夏、秋季；含水量夏季最低，冬季最高；脏器指数不存在两性差异；未成年个体的胴体及肺含水量高于成年鼠。更多还原

【Abstract】 Seasonal, age and sexual variation of weight and water content of internal organs in Rattus norvegicus were studied in this paper. Results as following: weight of heart, liver, lung and kidney positively correlated with they weight, but relative weight of those organs negatively correlated with body weight, and relative weight of those organs in spring and winter are higher than that in summer and autumn. Young individuals have relatively large heart and kidney. Water content of organs in Rattus norvegicus are lowest in summer and highest in winter. Water content of carcass and lung in young individuals are higher than that in edult individuals.更多还原
