Metabolism of 25-[3H]hydroxyvitamin D3 was studied in peritoneal macrophages from renal failure patients on continuous ambulatory peritoneal dialysis (CAPD). Cells from 5 out of 8 patients with a history of peritonitis produced significant amounts of a metabolite chromatographically identical to 1 alpha,25(OH)2D3; but none was produced by cells from non-infected patients. The evidence strongly suggests that peritoneal macrophages stimulated by infection can metabolise 25OHD3 to the active vitamin D3 metabolite, 1 alpha,25(OH)2D3, when maintained in short-term primary culture.
对接受持续性非卧床腹膜透析(CAPD)的肾衰竭患者的腹膜巨噬细胞中25 - [³H]羟基维生素D3的代谢情况进行了研究。8例有腹膜炎病史的患者中,有5例患者的细胞产生了大量色谱行为与1α,25(OH)₂D₃相同的代谢产物;但未感染患者的细胞未产生该代谢产物。有充分证据表明,感染刺激的腹膜巨噬细胞在短期原代培养时能够将25OHD₃代谢为活性维生素D3代谢产物1α,25(OH)₂D₃。
