Abstract: Using the pathologic technique，skin structures of Landraee pig and human were compared．According to our study，the skin of Landrace pigs and human is similar，both of them are composed of epidermis，dermis， subcutaneous tissue and cutaneous adnexa．However，compared with human，there are minor differences in pig adnexa：the hair follicle of the pig is more larger；most of sweat glands are apocrine sweat glands，and a few of them are eccrine sweat glands；sebaceous glands are less developed and fewer in number，and lipid droplet in cytoplasm is small．After breeding for several ten years in Xinjiang，nevertheless，the Landrace pigs are still the xenoskin providers for cure of large area deep bums，and the optimal animal models for wound healing， xenotransplant and immunological rejection researches．

摘要： 用常规病理切片技术，对新疆长自猪的皮肤组织结构与人的皮肤进行初步比较，为长白猪的实验动物化及治 疗大面积烧伤提供生物敷料和相关的移植研究提供实验依据。结果表明，长自猪与人的皮肤在分层上相似，都是 由表皮、真皮、皮下组织及皮肤的附属器构成。但也存在差异，长白猪皮肤的毛囊比人的毛囊粗大，汗腺多为大汗 腺，极少有小汗腺，皮脂腺在分布位置上与人相同，但不发达，数量极少，胞浆中脂滴颗粒细小。但在新疆的特殊地 理环境下培育数十年，长白猪是大面积深度烧伤治疗中异种皮片的提供者，也是创伤愈合机理研究及异种器官移 植免疫排斥机制研究适合的动物模型。
