Kanglemycin C vs ciclosporin on immunosuppression in mice

Jiang-ming Li, Zhi-bin Lin


To study inhibitory effects of kanglemycin C (Kan) on the mouse immune system, and compare with the effects of ciclosporin (Cic).
Delayed hypersensitivity (DH) and cyclophosphamide-potentiated DH induced by dinitrofluorobenzene (DNFB); heart allograft and skin allograft; hemolysin; the phagocytosis of the peritoneal macrophage.
Kan (12.5, 25, 50 mg.kg-1.d-1, ig, 8 d) markedly inhibited DH and cyclophosphamide-potentiated DH induced by DNFB (P < 0.01), prolonged survival times of heart and skin allografts (P < 0.01), and decreased the content of hemolysin (P < 0.01), but had no significant effect on the neutral-red phagocytosis of the peritoneal macrophage (P > 0.05).
Kan had marked suppressive effects on cell-mediated and humoral-mediated immune responses, but no effect on phagocytosis of macrophage.
