Abstract

1 An attempt has been made to monitor simultaneously the changes in blood flow, histamine content, histidine decarboxylase (HDC) activity and mast cell population in rat skin isografts and allografts. 2 The histamine content in rat skin allografts during rejection was decreased in contrast with our earlier observation in rabbits. 3 Although no definite correlation has been found between blood flow changes, histamine content or HDC activity, a reciprocal relationship appeared to exist between histamine content and HDC activity in the skin grafts, which might be a reflection of the immunosuppressive activity of this amine. 4 The immunosuppressive agent, cyclosporin-A (20 mg/kg daily) was able to prolong skin allograft survival and prevent the changes in histamine and HDC activity in allografts. 5 Possible implications of these findings are discussed in relation to current knowledge concerning the interactions between endothelial cells, lymphocytes and mast cells/basophils in graft rejection.

摘要
  1. 已尝试同时监测大鼠皮肤同基因移植和异基因移植中血流、组胺含量、组氨酸脱羧酶(HDC)活性及肥大细胞数量的变化。2. 与我们早期在兔子身上的观察结果相反,大鼠皮肤异基因移植在排斥过程中组胺含量降低。3. 尽管在血流变化、组胺含量或HDC活性之间未发现明确的相关性,但皮肤移植中组胺含量与HDC活性之间似乎存在相互关系,这可能反映了该胺的免疫抑制活性。4. 免疫抑制剂环孢素A(每日20mg/kg)能够延长皮肤异基因移植的存活时间,并防止异基因移植中组胺和HDC活性的变化。5. 结合目前关于内皮细胞、淋巴细胞和肥大细胞/嗜碱性粒细胞在移植排斥中相互作用的知识,讨论了这些发现的可能意义。
