[Multi- and single-port laparoscopic surgery in the treatment of hydatid liver disease].

Objective: To compare the effectiveness of multi-port and single-port laparoscopic surgery in the treatment of hydatid cyst of the liver.

Material And Methods: There were 25 children with solitary hydatid cyst of the liver (CL-CE2) who underwent surgery in 2013-2017. Mean age was 10.

[Possibility of inverse development of morphological changes in the rat myocardium provoked by large doses of dopamine].

It is shown that Wistar male rats keeping without medication and stressful effects for a month after administration of big doses of dopamine for two weeks does not lead to complete inverse development of heart remodeling. A decrease of the heart's mass occurs mainly because of a decrease of the right ventricle mass. The greatest changes of the extracellular matrix take place in the right ventricle: collagen level grows more noticeably, edema of the extracellular space relieves, correlations between collagen and blood vessels, cardiac hystiocytes and blood vessels increase aggravating right ventricular remodeling.

[The prevalence of the arterial hypertension and associated risk factors among population of various gender and age].

To study the pubescent characteristics of the prevalence of the arterial hypertension, the hyperglycemia, the hypercholesterolemia, the overweight and their combination the comprehensive examination of 4837 citizen of the City of Veliki Novgorod and Novgorod oblast aged from 20 to 87 years was organized. The analysis revealed in the examined territory the higher prevalence of hypertension and other studied risk factors and their combination are strongly related to the gender and the age of population. The prevalence of the obesity and the hyperglycemia, the combination of the overweight with the arterial hypertension and the hyperglycemia and the combination of the arterial hypertension with the hyperglycemia as well are significantly higher in the female subpopulation and in the elder population.

[Age- and sex-related prevalence of overweight, arterial hypertension, hyperglycemia and their combinations].

Aim: To study sex and age characteristics of overweight, arterial hypertension (AH) and hyperglycemia prevalence as well as prevalence of their combination.

Material And Methods: Complex examination of Veliky Novgorod and Novgorod region 4837 residents (2081 men and 2756 women, age 20-87 years) comprised anthropometric measurements with calculation of the body mass index (Ketle index), measurements of blood pressure, fasting blood glucose, cholesterol levels, oral glucose tolerance test (GTT).

Results: Prevalence of overweight and obesity in males was 50.
