The spread of depressive disorders is extra high nowadays. Depressive disorders are widespread mental disorders in the structure of mental pathology, both causes of psychiatrists' visit, and causes of medical aid. The presence of depressive syndrome in patients with cardiovascular system leads to deterioration patient's condition and adaptive abilities and aggravates somatic abnormality. Adequate therapy causes their reduction, prevention of recurrence and decompansation of comorbid somatic pathology, and eliminates severe medical and prevents social consequences. The study of clinical aspects of depressive conditions which are accompanied with pathology is one of the direction not only psychiatric, but also common pharmacotherapeutic investigations. The aim of the investigation was to determine clinical, pharmacotherapeutic and biorhythmic peculiarities of depressive disorders in patients with comorbid cardiac pathology. And also assessment of efficacy of complex therapy based on chronotherapy principle was used. 50 patients (female patients) with depressive disorders were involved in this investigation. This was performed based on "Depressive disorders of organic genesis, characterized by somatic pathology" (F 06.35), "Somatoform disorder" of heart and cardiovascular system (F 45.30), "Mild depressive episode" (F 32.00), and also comorbid arterial hypertension confirmed by physician. Clinical, laboratory, clinical and psychopathological investigations using psychodiagnostic scales (scale HAMD-21, CGI-S, CGI-І) were used. Individual biorhythmic status was established and it requires medicamentous therapy. Comparing patients of both groups, it has been detected a group of patients in whom principles of chronotherapy, especially antihypertensive and antidepressive therapy were prescribed, dynamics of patient's improvement was better than in the investigated group where the principle of chronotherapy was observed.

Introduction: Incessant increase in the frequency and distribution of anxiety disorders stipulates searching, research and study of the mechanism of action of new substances for their correction, including the group of 2-oxoindolin-3-glyoxylic acid derivatives.

The Aim: To research the effect of N-(1-naphthyl) amide-2-oxoindolin-3-glyoxylic acid on monoaminergic system of subjected to experimental neurosis of rats.

Materials And Methods: The experiments were performed on male Wistar rats, who have weight 180-220g and were researching the effect of 2-hydro-N-naphthalen-1-yl-2-(2-oxy-1,2-dihydroindol-3-ylidene)-acetamide (compound 18) at a dose (12 mg/kg), by intragastric drug injection of subjected to experimental neurosis rats, during 30 days (1 time in three days), for monoamines content (epinephrine, norepinephrine, dopamine and serotonin) in the blood, their decay products (homovanillic acid, vanillylmandelic acid and 5-oxyindolacetic acid) in the urine and the ratio of end products of the reaction to their predecessors.

Research: It was established that during the preventive-therapeutic application of N-(1-naphthyl)amide-2-oxoindolin-3-glyoxylic acid, it effectively adjusts the level of monoamines, reducing the content of adrenaline and increasing the content of noradrenaline, dopamine and 5-HT in the blood. The compound also reduces the content of products exchange of mediators (HVA,VMA and 5-OIAA) in the urine. The 2-oxoindolin derivatives reduces the ratio between HVA/dopamine, VMA/(noradrenaline + adrenaline) and 5-OIAA/5-HT, it testifies about the normalizing of enzymes activity, which are involved in the process of exchange and maintaining the constancy of monoamines. The results show that in the mechanisms of anxiolytic action of compound 18, a significant role plays the normalization of content and exchange of neurotransmitters in the organism, which caused an experimental neurosis.

Conclusion: Compound 2-hydro-N-naphthalen-1-yl-2-(2-oxo-1,2-dihydroindol-3-ylidene)-acetamide by the experimental 30-day neurosis, was reducing the expression of neurotransmitter imbalance in the blood, apparently due to correction of enzymatic synthesis links and biotransformation of monoamines.
