目的测定树的脏器重量、脏器系数的生物学特性指标,并对脏器重量与体重的相关性进行分析。方法选用成年树27只,雌性15只,雄性12只,分别测定体重和6个主要脏器重量,并计算脏器系数。结果雌、雄树脑的重量差异极显著(P<0.01),心、肝重量之间差异也达到了显著水平(P<0.05)。而脑、肾的脏器系数之间差异均达到了显著水平(P<0.05)。雌性树心、肝、脾和肾均与体重呈显著的正相关,雄性动物的心脏与体重也呈现出显著正相关。结论雌、雄树的心重量、肝重量、脑重量、脑系数、肾系数具有差异,其体重与某些脏器存在一定的线性关系。
Objective To determine the biological characteristics of organ weight and organ coefficient in tree shrews and to analyze the correlation between organ weight and body weight. Methods Twenty-seven adult tree females, 15 females and 12 males were selected. The body weight and the weight of 6 major organs were measured and the organ coefficients were calculated. Results There was significant difference in weight between female and male trees (P <0.01). The difference between heart and liver weights also reached a significant level (P <0.05). However, the difference of organ coefficients between brain and kidney reached significant level (P <0.05). Female tree heart, liver, spleen and kidney were significantly positively correlated with body weight, male heart and weight also showed a significant positive correlation. Conclusion The results showed that there was a difference in heart weight, liver weight, brain weight, brain coefficient and kidney coefficient between male and female trees and their body weights had some linear relationship with some organs.
