豚鼠淋巴器官内肥大细胞的观察

The Examination of Mast Ceils in Lymphotic Organs in Guinea Pig

本研究以光学显微镜观察了5例3个月龄健康豚鼠的胸腺、脾脏、淋巴结、气管和食管的组织学切片.结果证明:(1)胸腺皮质内存在有前肥大细胞,它们在胸腺的培育下,可分裂分化为成熟的肥大细胞;(2)成熟的肥大细胞由胸腺髓质经血循到达次级淋巴器官的胸腺依赖区留居;(3)在体内,肥大细胞并非是均等分布于所有疏松结缔组织内,而是集中分布在易于受到外界刺激的上皮下疏松结缔组织内,并时常穿越基膜进入上皮组织而形成肥大细胞浸润.

Histotomy of thymus, Spleens. Lymph nodes, trachea and Esophagus in 5 three-month Guinea pig was examined With the optical microscope.the vesults are as follows: ( 1 ) there are precursor mast cells in the thymus cortex, which are fostered here and split up and differentiate into mast cells. ( 2 ) Mast cells are transported from the medulla of thymus to the thymus dependent area of secondary lymphatic organs through the blood courses. ( 3 ) Mast cells are not evenly distributed in all the Loose connective tissues in vivo, but concentrated in those under the epithelium, where they could easily get stimuli and pass throgh the basement membrane from time to time forming infiltration focal.
