ABSTRACT
72 Ginea pigs were prepared and randomized to demonstrate the adverse effects of long term therapy of cyclosporine A [Cy A] and other currentely used immunosuppressive drugs [methotrexate, azathioprine, prednisone of the spleen, liver and kidney and also to estimate the effects of these drugs on the brain monoamines content and plasma cortisol level. From our histopathological and biochemical findings, it was concluded that Cy A is the safest and least toxic drug as compared with the ordinary immunsupressive drugs. On the other hand, it was clear that Cy A is the only drug which rises the plasma cortisol level and brain monoamines content significantly and may had a role in the pathogensis of induced system ic hypertension and cushingoid features associated with prolonged administration of this drug, a point that may be taken in consideration in therapeutic uses of Cy A as a potent immunosuppressive agent in transplanted patients

The oral antischistosomal drugs [vansil and biltricid] were investigated experimentally on albino rats with paracetamol induced hepato-renal toxicity. A biochemical and histopathological studies were done on such animals and were compared with normal and paracetamol treated ones. It is found that vansil is less toxic than biltricid as the last one causes more hepatorenal affection together with pulmonary congestion which is lacking in the vansil treated ones. Both drugs produce no testicular changes
