ABSTRACT
The present work introduces data on studying the activity of pyruvate kinase (PK) and lactate dehydrogenase (LDH) and the state of the cardiovascular system in elderly and senile people who applied to polyclinic "Health zone" in Baku. 60 people on an enzimopatiya and 87 people on a condition of cardiovascular system were examined. The examined persons were found the decreased myocardial blood flow, ischemic heart disease (IHD), against increased PK and LDH. Statistically significant differences in the activity of enzymes depending on gender, age were established, and changes in the bioelectric activity of the heart during an ECG were detected.

The article concerns study of effects of polyclonal antibodies to serotonin-modulating anticonsolidation protein (SMAP) being in direct dependence on serotonin level and providing intracellular transduction of serotonergic signal, on positive reinforcement effect of morphine in rats. The task was formed in Wistar male rats in the model of morphine self-administration as a result of pressing of one of two levers attached to the wall, joined to the pump delivering each time 100 µg of morphine directly into the vena jugularis. In the 1st series of studies brain cingulate cortex and hypothalamus were taken from the rats achieved stable level of morphine intake and SMAP level was measured with indirect immune-enzyme assay. It was shown that in the morphine-self-injected rats SMAP level in the cingulate cortex is significantly upregulated (p = 0.01), while in the hypothalamus it was left unchanged. In the 2nd series of studies the rats with stable level of morphine intake were administered intraperitoneally with anti-SMAP rabbit polyclonal antibodies (experimental group) or non-immune γ-globulins (control group). Soon after antibodies administration the animals of the experimental group demonstrated manifold decrease of morphine intake lasted for 8 days (p < 0.008), whereas it did not change in the controls. SMAP upregulation in the brain cingulate cortex in the rats with stable morphine intake, obviously, indicates to its engagement in positive reinforcement effect of morphine. Blockade of SMAP activity with anti-SMAP antibodies in the nerve cells induced sharp decrease of morphine intake due to disturbances of transduction through intracellular serotonin's signal channels.

The developed modification may be used in clinical practice as a diagnostic test and in mass screenings for phosphoglycerate kinase deficiency: more than a hundred tests may be made in a day. If blood samples have to be sent by mail, their quality is unchanged for up to 7 days.
