摘　　要：目的观察不同种属肌组织形态的特征指标,建立种属鉴别的判别方程,尝试建立一种种属鉴别新方法。方法分别提取20名成年死者三个部位(肱三头肌、股二头肌和竖脊肌)的肌组织和达到出栏年龄的猪、羊、牛各20头三个部位(臂三头肌、股二头肌和背最长肌)的肌组织,制成石蜡切片。测量人及猪、羊、牛肌组织的11项观察指标,并应用统计学方法进行分析,建立种属判别方程。结果筛选出4项观察指标建立人与猪、羊、牛之间种属鉴别的判别方程,对人肌组织的判别准确率可达90%,对猪、羊、牛肌组织的判别准确率分别可达80%、100%和80%。结论形态学方法为人与猪、羊、牛之间肌组织的种属鉴别提供了一种新的方法,可为动物种属鉴别提供参考依据。Objective To observe the morphological characteristic indexes of the muscle tissues from different species and to establish a discriminant equation of species identification and tried to establish a new method for species identification. Methods Three different parts of the muscle tissues, triceps brachii, biceps femoris and erector spinae from adult human corpses, triceps brachii, biceps femoris and longissimus dorsi muscle from swine, sheep and cattle reached the slaughter age, were extracted respec- tively （20 for each group） and deal the tissues into paraffin sections. Eleven observational indexes of the muscle tissues from adult human corpses, swine, sheep and cattle were detected. Statistical methods were used to analyze the data and a discriminant equation of species identification was established. Results Four observation indicators were screened for establishing the discriminant equation of species identifica- tion among human, swine, sheep and cattle. The accurate rate of this method for human muscle tissue identification was 90%, and for swine, sheep, and cattle muscle tissue were 80%, 100% and 80% respectively. Conclusion The morphological method provides a new method for the species identification of the muscle tissue among human, swine, sheep and cattle, and it can be used as a reference for the identification of animal species.
