[The role of disorders in the homeostasis of divalent cations in the pathogenesis and clinical picture of bronchial asthma].

Mg and Ca concentrations in the serum, red cells, lymphocytes and 24-h urine were examined in 13 preasthma (PA) patients, 26 atopic asthma patients and 23 bacterial asthma (BA) patients. The patients' age ranged from 15 to 65 years. The measurements were made on AAC-508 absorption spectrophotometer (Hitachi, Japan) and Microlyte selective ionometer (Kone, Finland).

[Role of magnesium and calcium ions in the pathogenesis of bronchial asthma].

Nuclear absorption spectrophotometry (ACC-508, Hitachi, Japan) and selective ionometry (Microlyte, Kone, Finland) were used to measure Mg and Ca concentrations in the serum, red cells, lymphocytes and 24-h urine of 26 patients with atopic and 23 patients with bacterial bronchial asthma (BA) aged 15-65. Irrespective of BA variant, phase, severity and bronchial obstruction, the blood of the examinees contained insufficient quantities of Mg and excessive ones of Ca. 24-h urinary excretion of Mg was subnormal.

[Effect of cAMP modifiers on the cytotoxic activity of macrophages].

The effects of various cAMP modifiers on the changes in the intracellular cAMP level and on the coupling of the cAMP system with realization of macrophage cytotoxicity depending on their functional activity were studied. Nonactivated and activated by E. coli polysaccharides peritoneal macrophages of BALB/c mice and macrophage-like cells of J744 mice were incubated in the presence of cAMP modifiers and further assayed for cytolytic and cytostatic activities.
