Experiments on narcotized cats showed that intraatrial injection of dalargin in doses crossing and not crossing the blood-brain barrier modifies impulse activity of nodose ganglion neurons.

Acute experiments on cats showed that dynorphin A(1-13) modulates pulse activity of afferent neurons and interneurons in the bulbar cardiovascular center against the background of stable blood pressure.
The role of the autonomic nervous system in the development of ischemic cardiac arrhythmias was studied in acute experiments on cats receiving thyrotropin-releasing hormone. Bilateral vagotomy attenuated, while bilateral transection of cardiac branches of the stellate ganglia completely abolished the antiarrhythmic effect of thyrotropin-releasing hormone.
Acute experiments on narcotized cats showed that intravenous injection of thyrotropin-releasing hormone (20 microg/kg) inhibited discharge activity of most afferent neurons and interneurons in the bulbar cardiovascular center.

Acute experiments on cats showed that intravenous injection of thyrotropin-releasing hormone prevented blood pressure drop and produced a pronounced antiarrhythmic effect.
Preliminary intravenous injection of thyrotropin-releasing hormone in a dose of 20 g/kg to cats with developing myocardial ischemia during stimulation of the cerebrocortical sensorimotor zone had a pronounced antiarrhythmic effect.
Effects of intravenous injection of DAGO on impulse neuronal activity of the bulbar cardiovascular center were studied in acute experiments on cats narcotized with Nembutal. DAGO-induced changes in activity of sensory neurons and interneurons were unidirectional and preceded hemodynamic shifts. The antiarrhythmic effect of DAGO is due to its direct action on neurons of the bulbar cardiovascular center.
In acute experiments on Nembutal-anesthetized cats, the effect of opiate receptor agonists DAGO, DSLET, and dinorphin A(1-13) on the incidence of idioventricular rhythm disturbances, including ventricular tachycardia and fibrillation, was studied under conditions of occlusion of circumflex branch of the left coronary artery and stimulation of the sensorimotor cortex. The most pronounced effects were observed with DSLET and dinorphin A(1-13). These preparations completely prevented ventricular fibrillation. DAGO produced a less pronounced protective effect probably because of parallel increase in plasma catecholamine concentration.

11 patients with confirmed chronic HCV-hepatitis were treated with high-dose interferon. 12 matched controls were treated conventionally. Higher response was registered in patients on the interferon treatment. Side effects were not related to the variant of interferon therapy in the studied population.
AIM: Detection of viral hepatitides markers in patients with alcoholic damage to the liver. MATERIALS AND METHODS: Virological, immunological and histochemical tests were performed in 36 chronic alcoholics who had enlarged liver and/or abnormal hepatic characteristics. RESULTS: 60% of the examinees carried chronic HBV, HCV, HDV infection. The activity of chronic inflammation of hepatic parenchyma was associated with biological phase of the viral infection development. The degree of hepatic parenchyma morphological changes was unrelated to the virus type. (HBV, HCV, HDV). CONCLUSION: Alcoholic hepatic damages often combine with viral hepatitis.
