    Streszczenie angielskie: Decreased susceptibility to apoptosis and impaired proliferative control are throught to be responsible for prolonged life spain and accumulation of chronic lymphocytic leukaemia (B-CLL) cells. The acitivity of calpains (calcium-dependent, neutral proteases, active in the cells responding to signals inducing a rise of cytoplasmic (Ca++) is involed in the regulation of apoptosis of some cell types by interaction with caspase-3. This work verifies the hypothesis of the abnormal activity of calpains and its role in reduced apoptosis of the BCL cells. Casein zymography, reverse transcriptase-polymerase chain reaction, and Western blotting were used for identification and quantification of the activity and expression of calpains (calcium-dependent, neutral proteases, active in the cells responding to signals inducing a rise of cytoplamic (Ca++) is involved in the regulation of apoptosis of some cell types by interaction with caspase-3. This work verifies the hypothesis of the abnormal activity of calpains and its role in reduced apoptosis of the B-CLL cells. Casein zymography, reverse transcriptase-polymerase chain reaction, and Western blotting were used for identification and quantification of the activity and expression of calpains in B-CLL cells and purified B lymphocytes. The activity and expression of ć-calpain (requiring micromolar Ca++ for activation) are significantly higher in the leukemic than in nonmalignant cells. Conctrarily, the activity and expression of m-calpain (requiring milimolar Ca++) as well as the expression of calpastatin (an endogenous inhibitor of...

    Streszczenie angielskie: The relationship between the secretion of interleukin 10 (IL-10) and nitric oxide (NO) by hamster peritoneal marcophages and their cytotoxic effects on the cells of those two melanoma lines was studied. The nonuniform reaction of macrophages from hamsters bearing two transplantable melanoma lines has been observed. An increase in the cytotoxicity of macrophages from hamsters bearing the amelanotic melanoma line was accmpanied by an inverse correlation between IL-10 and NO secretion. Such a relationship was not found in the case of macrophages from animals bearing the native-melanotic melanoma line. It is suggested that the phenotypical changes of melanomas connected with their progression modified the cytotoxic and secretory activity of the macrophages with regard to IL-10 and NO.
