Myocardial and endocardial lesions in rabbit after acute poisoning with Intration and after treatment with some detoxifying agents.

The hearts of rabbits killed 24 hours after intoxication with Intration in the dose of LD50 and rabbits treated at the same time with PAM or atropine were studied pathomorphologically. Twenty-four hours after administration of Intration toxic lesions of the myocardium and endocardium were observed, which were more pronounced in rabbits treated simultaneously with the detoxifying agents as compared with those which received only Intration. The intensity of the changes was due to overdosage of the detoxifying agents, especially PAM which was particularly harmful.

Renal pathomorphology and histochemistry in dog after hemodilution as well as after administration of full blood in extracorporeal circulation in dog.

Dog kidneys were studied morphologically and histochemically after hemodilution to a 10--20% hematocrict value and transfusion of whole blood under conditions of extracorporeal circulation ensuring constant (linear) flow. Marked interstitial edema in the dog kidneys after hemodilution was the most pronounced alteration, attributed to disorders in the capillary circulation depending upon the apparatus employed. This conclusion was supported by similar changes in animals subjected to various degrees of hemodilution. Widening of the glomerular space and compression of renal tubules were the direct consequences of interstitial edema. Histochemical reactions revealed damage of the cell membranes. Swelling of the ergastoplasm and lysosomes was interpreted as secondary to disorders in circulation of tissue fluid. The least pronounced changes concerned the mitochondria. After extracorporeal circulation with whole blood, thrombi and fat emboli were observed in the blood vessels of the renal glomeruli, attributable to damage of blood in the extracorporeal circulation apparatus.

[Laboratory and oligobiopsy studies of the liver in patients with psoriasis treated by the combination of Tigason-PUVA-cignoline (RePUVA+C)].

In 10 patients with generalized psoriasis treated by this method biochemical and histological examinations of liver biopsy specimens were done before and after 60 days of the treatment. In some cases a transient rise of A1AT activity, raised activity of alkaline phosphatase and gamma-glutamyltranspeptidase were noted. Histological examinations demonstrated slight hepatocellular damage with microfocal necrosis, fatty infiltration of some cells and increase in the structural elements of cytoplasm.
