[The effect of sodium oxybutyrate on various regulatory mechanisms of pulmonary hemodynamics in experimental tuberculosis in dogs].
    Problemy tuberkuleza, 1991, Issue:12

    The role of cyclic nucleotides and prostaglandins E1 and F2 alpha in pulmonary hypertension formation was elucidated in experimental tuberculosis in dogs and the mechanism of a hypotensive action of sodium oxybutyrate specified with consideration of its influence on the non-gas exchange pulmonary function. The level of the above compounds was studied in the blood taken from the pulmonary artery and aorta in comparison with pulmonary artery pressure prior to and after intravenous injection of sodium oxybutyrate, an antihypoxant. Pulmonary vessel tone was found to depend on the cGMP content and synthesis in the lungs both in health and in tuberculosis and pulmonary hypertension in tuberculosis was associated with a deranged level and correlation of cAMP, cGMP and prostaglandins E1 and F2 alpha in pulmonary circulation. It has been demonstrated that the hypotensive effect of sodium oxybutyrate is associated with its influence on these biochemical parameters in plasma.

[Mechanism of the hypotensive effect of sodium oxybutyrate in pulmonary hypertension in experimental tuberculosis in dogs].
    Problemy tuberkuleza, 1989, Issue:5

    The mechanism of sodium oxybutyrate effect on the lung vessels under normal conditions and under conditions of experimental tuberculosis in dogs was studied by the time course of pressure in the pulmonary artery and the content of serotonin, histamine and adenosine in blood of the aorta and pulmonary artery after the drug intravenous administration. To confirm the antihypoxic effect of sodium oxybutyrate, the levels of lactate, pyruvate, ATP, ADP and AMP were investigated. The levels of adenosine were judged indirectly by the activity of 5-nucleotidase, adenosine desaminase and AMP. It was shown that the decrease in pressure in the pulmonary artery after the use of sodium oxybutyrate was connected with the drug antihypoxic effect which led to lower levels of histamine in the aorta blood under the normal conditions and to higher levels of adenosine under the conditions of tuberculosis.
