Diabetes type 1 and type 2 in pregnancy results in increased risks to both the mother and child. Beside the high rate of spontaneous abortions, babies are at increased risk of congenital malformations, perinatal mortality, macrosomia and related complications, which is thought to be attributable to poor glycemic control.
The aim of our current study is to evaluate whether oral administration of rhododendron leaf extract gives us possibility to avoid or reduce undesirable outcome by modulating mechanisms underlying diabetes-induced pregnancy loss. To clarify this question, we performed the study in streptozotocin (STZ) treated FVB female mice. To investigate influence of RhE administration on pregnancy loss in diabetic mice depending on severity of diabetes, mice daily were intook 66,67 mg/kg RhE two weeks before crossbreeding and during implantation period. Therefore, pregnancy rate and resorptions quantity were investigated on day 9 of pregnancy, when implantation period is completed.
To characterize influence of RhE administration on expression of IL-10, TNFα, and NO in the uterine cells of diabetic mice, we analyzeduterine lysates of diabetic mice collected on days 5 and 7 of pregnancy, encompassing the period of implantation. In conclusion, the data presented in this article suggest that IL-10 and TNFα play a central role in the pathogenesis of diabetes-induced pregnancy loss. Also, RhE oral administration reduces nitric oxide generation in uterus, but do not normalize pro- and anti-inflammatory cytokine production. Although, Rhododendron Extract had a strong inhibitory effect on NO secretion but cannot regulate the mechanisms determining the outcome of diabetes-induced embryopathic stress.

Tbilisi State Medical University, Department of Pharmacotherapy, Tbilisi, Georgia
J. Experimental and Clinical Medicine, 2017, 1, pp.22-27
The aim of the study was assessment of the effectiveness of corvitin and acetylcistain, as well as of combination of above named drugs in mouse model of paracetamol (acetaminophen) induced acute hepatitis. Experiments were carried out on white, male mice (n=49) fitting established standard criteria. All investigational drugs in experimental groups of animals were administered 1,5 h before induction of hepatitis and after its creation by paracetamol (750mg/kg i/p) during 3 days by a single dose. In the control group of animals saline solution was administered in equivalent quantity. The efficacy of used drugs were determined by the following criteria: mortality, level of biochemical markers of hepatocytes cytolysis (ALT,AST) and liver mass. Obtained results were statistically processed.
In acute hepatitis it was shown profound alteration of the level of hepatic biochemical markers and liver mass that accompanied by high mortality. Hepatoprotective activity of corvitine and acetylcistain in case of their separate administration was similar. Combined administration of the drugs has shown the greatest hepatoprotective efficacy. Presumably corvitin prodused preventive and curative effects due to its antioxidative properties, while hepatoprotective effect of acetylcisteine was revealed by its antioxidative and SH-groups donator properties.
It was suggested that the combination of corvitin and acetylcistein would become in near future an effective remedy for correction of hepatic function during its severe damages and reduction of mortalitis.

Recently, the physiological role of the growth hormone (GH) in adult life has received much attention. According to data, received from numerous studies, GH has an important role, regarding the lipid and carbohydrate metabolism [1,2].
GH replacement therapy is crucially important for the adults with Hypopituitarism, which are highly vulnerable to increased vascular mortality and morbidity [3,4]. Those issues are the consequences of the dyslipidemia, which is seen in the patients with growth hormone deficiency.
GH replacement therapy in hypopituitary adults seems to produce beneficial effects on the plasma lipid profile. Therefore, has a huge importance in metabolic and weight regulation.

It is well known that fetal antiepileptic drugs (AED) exposure is associated with an increased risk of congenital malformations, cognitive impairment and autistic spectrum disorders.
The aim of the study was to investigate AED exposure influence on different aspects of cognitive functioning and risk of autistic spectrum disorders in children exposed in utero AED.
METHODS: 100 children from 3 to 6 year were participated in the study: 50 children of WWE received AED treatment during pregnancy and 50 children of women without epilepsy, control group (CG). All children underwent Wechsler Preschool and Primary Scale of Intelligence Test. Verbal and Non-verbal abilities, Full Scale IQ was calculate for each child.
RESULTS: The Verbal Comprehension Index was higher in children from CG group (mean – 97.06), compare to AED exposed children (84.4). Verbal concept formation, knowledge acquiredand verbal reasoning scores were significantly lower in children of WWE compare to control group.
Visual Spatial Index was higher in unexposed individuals (mean – 101,5), compared to exposed children (86,4). Understanding part-whole relationships, organizing visual information, attending to visual detail and integrating visual and motor functions also were better in children from CG group.
The Full Scale IQ was significantly higher in children from CG group (101,5), compare to children of WWE (84.02).
When compare exposed children of WWE with different AED treatment, no significant difference revealed in cognitive functioning and Full Scale IQ scores.
CONCLUSION: In utero AED exposure may worsen child early cognitive development in general. It hinders development both, verbal and non-verbal cognitive abilities of preschool children.

Considering the impact of vitiligo on the psyche and self-esteem of the patient, the use of camouflage technology is very significant for the proper and global management of disease. To hide a cosmetic skin defect various cosmetic means are offered. It is now widely used tanning, coloring and bleaching lotions, liquid and compact base, fixing powder and sprays, semipermanent and permanent tattoo.
The aim of the study was to determine the effectiveness of camouflage in the complex treatment of patients with acrofacial vitiligo.
18-65 years old 35 patients with acrofacial form of vitiligo (20 women and 15 men) with disease duration from 1 to 15 years were under clinical observation. Vitiligo depigmented lesions were located on the face (around the eyes, and the mouth) on the upper limbs (dorsal surface of the hands with partial transition to the palms). All the patients received local UVB 311 phototherapy of vitiligo lesions (portable device of Dr. Honle company). Patients underwent phototherapy sessions 3 times a week (treatment procedure envisaged 15 courses), observed patients were divided into 2 groups; main group and the comparison (control) group. According to data of different authors and results of own observations vitiligo lesions on the hands turned out to be the most difficult to treat. Based on this, the patients of main group for camouflage of lesions on the hands were using tonal pencil “ZANDERM”. As we know vitiligo represents a significant cosmetic defect, which has an aggravating effect on the course of dermatosis and psychological conditions of patients
To study some psychological peculiarities observed in vitiligo patients before and after treatment (4 months) we used the “personal anxiety scale”. Both groups of patients before treatment have shown the high level of anxiety (25-40) points. After the combined treatment with phototherapy and the tonal pencil, the level of anxiety in the study (main) group was significantly reduced (5-15 points). While in comparison group they remained on the high level. Along with the positive dynamics of the level of anxiety in the main group, earlier appearance of repigmentation was observed on the face, and the repigmentation was homogenous without signs of desquamation and hyperkeratosis.
Thus, the complex treatment of patients with vitiligo by means of camouflage not only gives a positive cosmetic effect but also has positive influence on some of the psychological conditions of vitiligo patients.

The structure of diseases in Georgia has changed dramatically - sharply increased the number of non-communicable diseases, mental disorders and drug addiction. It should be noted that Georgia’s health care system over the years was focusing on the technologies, which would require a sophisticated hospital care, high-tech operations and less attention was paid to disease prevention, early detection and their effective managment. Therefore special attention should be given to the access to the primary health care system and to increase its role, as in the countries where the medical services is oriented on the primary health care model, the satisfaction of the population is high, the prevention services are better developed, they are characterized by the better indicators of health and less health care expenses.

It is well known that foetal AEDs exposure is associated with an increased risk of congenital malformations, cognitive impairment and autistic spectrum disorders.
The aim of the current study was to assess the effects of foetal AEDs exposure on the seizures and epileptiform EEG discharges in children.
A prospective cohort group of children aged 3-6 years (MD - 4.5 years) with fetal exposure to AEDs from mothers with epilepsy (Case-group) was formed. Age matched individuals without fetal AEDs exposure from healthy women were enrolled as a control group. In all of the 96 children from case (n=47) and control (n=49) groups standard EEG and neurological/epileptological examinations were performed.
Specific epileptiform EEG-discharges and nonspecific EEG abnormalities were observed in 21% of children from case group (10/47); in one child (2%) of control group specific epileptiform EEG discharges (spike and wave discharges), without clinical seizures (1/49) were revealed. Epilepsy was diagnosed in three children (6%) from case group: two of them were siblings with foetal VPA exposure and focal epilepsies were diagnosed in the both of them. In the remaining one child of the mother with reflex epilepsy and foetal VPA-exposure, reflex epilepsy was diagnosed.
Epileptiform EEG discharges are tenfold and the seizures are three times as often found in children with fetal AEDs exposure from mothers with epilepsy than in their healthy peers from healthy mothers. These effects may be due to epilepsy itself or foetal AEDs exposure may play some role that needs further research.
