[Features of lipid metabolism in patients of different sexes and ages with dyscirculatory encephalopathy].

Lipid metabolism was studied in 312 males and females of young, middle, elderly and senile ages with dyscirculatory Stage I and II encephalopathy induced by atherosclerosis, arterial hypertension, or their combination. The control group was composed of 216 clinically healthy age-matched subjects. Marked hyperlipidemic shifts in the form of hypertriglyceridemia (HTG), hypercholesterolemia (HC) and hyperbetalipoproteinemia (HBL) were found in patients of both sexes under 45 years of age: HC and marked HTG were significantly more frequent in males. In middle-aged patients marked HTG was more common in males and HC in females. Elderly and senile patients as compared with young and middle-aged ones were characterized by a low cholesterol coefficient of atherogenicity and high levels of high density lipoproteins with antiatherogenic action. The most frequent type of hyperlipidemias in patients of all age groups was IIa, Types IIb and IV were observed less commonly.

[The molecular genetic typification of planarians in the genus Bdellocephala (Dendrocoelidae, Tricladida, Turbellaria) from Lake Baikal with an assessment of their species diversity].

Baikal planaria from genus Bdellocephala were typified using rDNA locus coding 5'--end domain of 18S ribosome RNA. Five colour forms of 24 possible variants that differ in diapason 0-1.3% of genotype were determined by comparative analysis of nucleotide sequences. The authors use back colour--one of the most variable and typical character in the given group--to collect material for investigation. It allows to minimize the size of investigation sample and at the same time to cover maximum variability of Bdellocephala. One of the positive result of molecular typification of colour forms was a discovery of unique individuals that belong to new species. Karyological analysis of colour forms shows variations in chromosome numbers that divide planaria into 3 groups (2n = 20, 24, 26). Comparative analysis of morphological and ecological characters and karyotypes of some forms united by the same genotype allows to distinguish them as separate species. Criteria of modern phenetic system of Baikal planaria are discussed.
