Abstract:Given in subtoxic doses to the rat, ergotamine produced tail gangrene in not more than 20% of animals. The incidence rate of ergotamine gangrene was not influenced by acute Mammation (carrageenin, dextran oedema).

The gangrene-inducing effect of ergotamine was significantly increased in rats with adjuvant arthritis or 6-sulphanylamido-indazole arthriti… Show more
