[Morphological characteristics of cardiomyocyte death in the experimental myocardial infarction in rats with various emotional reaction].

The peculiarities of morphological signs of cardiomyocyte death in the lesion focus in experimental myocardial infarction were studied. Infarction was induced by ligation of descending branch of the left heart coronary artery in outbred rats with 180-200 g body mass, which were previously subdivided into highly emotional (HE) and low emotional (LE) groups according to "open field" test. Microscopic study has shown that in the infarction focus of animals of both HE and LE groups cardiomyocyte death types were found that differed primarily by the state of myofibrils.

[Effect of treatment with perftoran on the course of experimental uveitis, lipid peroxidation and activity of antioxidant defense enzymes].

Experimental uveitis is characterized by a pronounced lipid peroxidation (LPO) in damaged tissues of eye, which is complicated by reduced activity of the antioxidant enzymes, SOD and catalase. The intensification of LPO was also found in blood serum and hepatic tissue. However, hepatic lipid peroxidation was accompanied by compensatory increase of catalase activity.

[Pancreatic enzyme activity in early phases of acute experimental pancreatitis in rats].

Experiments were performed on laboratory rats with acute pancreatitis caused by local freezing the pancreas with chlorethyl. An active action of enzymes alpha-amilase, lipase, phospholipase A2, was revealed. During the first hours, an increase in action of all three enzymes, particularly that of phospholipase A2, was found.

Koebner reaction in psoriasis due to secondary syphilis.

A patient with a two-year history of psoriasis showed a widespread eruption that was clinically and histologically similar to psoriasis. Results of blood tests revealed syphilitic infection, appearing to be secondary syphilis. The flare-up of guttate psoriasis was considered to represent a Koebner phenomenon due to secondary syphilis.
