The pharmacodynamic effect of a 7-day oral treatment with a suspension of Coprinus comatus at doses of 0.835 and 1.670 g/kg in rats was studied. Changes in body weight, bile secretion and hypoglycaemic action were examined together with antipyretic activity and paw oedema tests. Such treatments resulted in a significantly lower increase in the body weight of tested animals (15.73 ± 8.36 g/rat in the untreated group, 8.44 ± 8.23 g/rat (p < 0.05) and 3.18 ± 7.93 g/rat (p < 0.05), for C. comatus 0.835 and 1.67 g/kg, respectively). Hypoglycaemic action was evident only in the glucose load test (6.79 ± 0.61 to 9.70 ± 1.16 (p < 0.05) in the untreated group and 6.47 ± 0.35 to 7.27 ± 0.76 for C. comatus 1.67 g/kg). Histological examination of pancreas cross-sections suggested certain protective functions of the mushroom suspension in alloxan poisoning. In the antipyretic test, a significantly lower increase in body temperature was observed in the mushroom-pretreated rats. In the paw oedema test, no decrease in oedema induced by formalin injection was observed following treatment with C. comatus.
