| Abstract: | Treatment of rats with histamine releaser compound 48/80 caused changes in blood leukocyte populations. An increased number of PMN-leukocytes was observed. Tritoqualine only modestly reduced the number of granulocytes. In animals treated with compound 48/80 an activation of PMN-leukocyte latent collagenase of up to 80% was observed. This activation was partially inhibited (about 40%) in animals pretreated with tritoqualine. The results presented suggest that the beneficial effect of tritoqualine in allergic diseases may be in part connected with an indirect inhibition of collagenase activity. |
