ABSTRACT
Fas-induced apoptosis plays an important role in the mechanisms of tissue injury in myocardial infarction. The level of membrane Fas mRNA was elevated during the postinfarction period in the blood of patients and did not change in response to levocarnitine. The mRNA level of soluble Fas, inhibiting Fas-dependent apoptosis, remained normal during the first 7 days, but increased 14 days after myocardial infarction, which corresponded to previously detected increase of serum level of soluble Fas molecules. Addition of levocarnitine, inhibiting Fas-dependent apoptosis, to therapy caused no changes in the level of soluble Fas mRNA, presumably because of similar effects of soluble Fas and levocarnitine on the apoptotic processes in myocardial infarction.

The levels of interferon-y (IFN-gamma), tumor necrosis factor-gamma (TNF-alpha), and interleukin-8 (IL-8) and their changes during chemotherapy and laser chemotherapy were studied in 97 patients with active infiltrative pulmonary tuberculosis, by taking into account Mycobacterium tuberculosis (MBT) sensitivity to chemical agents. The studies have indicated that the levels of IFN-gamma, TNF-alpha, and IL-8 are increased and may be markers of an active process. Chemotherapy causes a reduction in increased cytokinemia. Complex laser chemotherapy affects the cytokine profile in active tuberculosis caused by not only drug-sensitive, but also drug-resistant MBT.
