Quinalphos given in daily oral doses of 0.5 mg/kg for 110 days induced severe signs of organophosphorus poisoning in male goats. The inhibition of acetylcholinesterase activity in erythrocyte was highly significant. The activity of liver glutamic; oxaloacetic transaminase, glutamic; pyruvic.transaminase, alkaline phosphatase and protein indicated marked alteration. The haematological changes were however, relatively less significant with the exception of a very low count of red blood cells and white blood cells in the treated animals. Among the vital organs, only liver suggested mild cellular changes due to quinalphos intoxication. There was no significant pathological change in other organs of the treated animals.
In animals observed after 15 and 30 days rest, the activity of acetylcholinesterase in red blood cells and haematological picture showed a fairly good recovery. This study suggests that although quinalphos in low concentrations did not produce discernible cellular changes, it induced highly significant enzymatic and haematological changes in the goat.

Male and female albino rats (Wistar strain) were given single and multiple doses of karaya gum suspended either in peanut oil or mixed with basal diet at different concentrations ranging from 0.5 to 8 g gum/kg body weight. The plant gum did not elicit any overt signs of toxicity or death in both sexes of rats.
Daily administration of karaya gum mixed with basal diet at different dose levels (0, 5, 20 and 40 g gum/kg diet) for a period of 90 days showed no adverse effects in male and female rats. The body weight, growth pattern, food and water intake were comparable with those of the normal rats. There were no significant biochemical, or morphological alterations in the vital organs of experimental animals.
