在器官移植时,了解其组织中血型物质抗原的分布,对研究和预防移植体的排斥,有很大作用。为此本文研究了成人胰组识内血型物质的分布。血型物质抗原用简接免疫萤光法测定。测定结果:(1)胰组织内无抗原I和i存在。(2)A、B、H抗原存在于腺泡细胞顶部的胞浆内,亦存在于血管内皮细胞表面。在腺泡细胞顶部亦存在分泌颗粒和胰组织特异性同种抗原。腺泡细胞膜不具有A、B、H
At the time of organ transplantation, understanding the distribution of blood group material antigens in their tissues plays a significant role in the study and prevention of graft rejection. In this study, we studied the distribution of blood type substances in adult pancreatic tissue. Blood group antigen by simple immunofluorescence assay. Determination results: (1) pancreatic tissue without antigen I and i exist. (2) The A, B and H antigens exist in the cytoplasm of the top of acinar cells and also exist on the surface of vascular endothelial cells. Secretion of granules and pancreatic tissue-specific alloantigens are also present at the top of acinar cells. Acinar cell membranes do not have A, B, H
