Combination of preventive and repeated (after 12 h) intravenous injection of zafirlucast in daily dose of 40 mg/kg to rabbits with epinephrine-induced heart injury essentially decreased the content of leukotriene C(4), but did not prevent the increase of leukotriene B(4) concentration in the blood, though drcreased its content in comparison with the level observed 24 h after epinephrine injection by 11%. Two injections of zafirlucast had a favorable impact on serotonin content in the myocardium (this parameter decreased by 19%), promoted a decrease in epinephrine content and normalization of the norepinephrine/epinephrine ratio, did not change prostaglandin content and ratio, and slightly diminished histamine concentration in the myocardium. The effect of zafirlucast can be explained by a reduce of oxidative stress. Zafirlucast decreased blood content of myofibrillar fraction of creatine phosphokinase (by 22%). These result suggest that zafirlucast can be added to combined therapy of necrotic, stress-induced, hypoxic, and ischemic injuries of the myocardium. |
