[Suppressive effects of lanoconazole on arthus phenomenon in vivo and on production and functions of TNF in vitro].

| Abstract |
The anti-inflammatory effect of lanoconazole (LCZ) was investigated in vivo and in vitro. The effect of LCZ was evaluated on the inflammatory reactions elicited by intradermal injection of ovalbumin to ovalbumin-immunized rabbits, as an Arthus phenomenon. A one or two % cream preparation of LCZ was topically applied on the lesion daily after challenging injection until the inflamation had diminished. By macroscopic observation and measuring the diameter of edema, erythema, hemorrhage and necrosis, the effects of LCZ on the reactions were compared with the reactions of the sites administered withcream vehicle as reference agent. Two % LCZ showed an anti-hemorrhagic effect. The in vitro effect of LCZ on production and functions of an inflammatory cytokine, TNF was also examined. LCZ suppressed the production of TNF by murine peritoneal macrophages at 20 micro g/ml and the adhesion of neutrophils at 100 micro g/ml. Moreover, LCZ significantly suppressed the growth inhibitory activity of TNF against L929 fibroblasts at 0.5 micro g/ml. A very low concentration of LCZ might protect the fibroblasts from immunological cytotoxicity in vivo. These findings suggest that LCZ has a suppressive activity to inflammatory responses and this suppressive action may be due to its protective activity to cells like fibroblasts.
