Assurance of the existence of a trans-boundary population of the snow leopard (Panthera uncia) at Tsagaanshuvuut - Tsagan-Shibetu SPA at the Mongolia-Russia border.

The existence of a trans-boundary population of the snow leopard (Panthera uncia) that inhabits the massifs of Tsagaanshuvuut (Mongolia) - Tsagan-Shibetu (Russia) was determined through non-invasive genetic analysis of scat samples and by studying the structure of territory use by a collared female individual. The genetic analysis included species identification of samples through sequencing of a fragment of the cytochrome b gene and individual identification using a panel of 8 microsatellites. The home range of a female snow leopard marked with a satellite Global Positioning System (GPS) collar was represented by the minimum convex polygon method (MCP) 100, the MCP 95 method and the fixed kernel 95 method.

Systematics and Distribution of Ferret Badgers Melogale (Mammalia, Mustelidae) in Vietnam: First Genetic Data.

Genetic studies of the ferret badgers Melogale conducted in Vietnam have shown that this area is inhabited by three species, M. moschata, M. personata, and M.

[Odontologic anomaly in the American mink Neovison vison (Carnivora, Mustelidae) and possible reasons for its appearance].

The paper describes the phenomenon of substitution of the reduced M2 with a tooth of a complex structure in the American mink Neovison vison Schreber. The anomaly is observed on three skulls out of the 574 examined (0.52%) and is characterized by a clear localization, identical structure, and symmetrical manifestation.

[Population aspects of sexual dimorphism in guild of the Mustelidae: Mustela lutreola, Neovison vison, Mustela putorius, Martes martes as an example].

Size sexual dimorphism was investigated on 695 skulls of four Mustelidae species. By extent of increasing of differences between sexes the species are placed in following order: European pine marten (Martes martes), European mink (Mustela lutreola), American mink (Neovison vison), and European polecat (Mustela putorius). Extent of the dimorphism characterizes ecological plasticity of the species and is population characteristic.

[Polymorphism of the mitochondrial DNA control region in the population of raccoon dog (Nyctereutes procyonoides Gray, 1834) introduced into the Upper Volga basin].

Analysis of sequences (n = 30) of a hypervariable segment (599 bp) of the mtDNA control region in raccoon dog Nyctereutes procyonoides Gray, 1834, introduced into the Upper Volga basin, revealed a high level of molecular genetic variation. Two statistically significantly different haplogroups were identified. These haplogroups, however, were not associated with spatial geographic structure of the population.

[Introduction of species and microevolution: the European beaver, raccoon dog, and American mink].

Nine skull samples of the beaver Castor fiber, six samples of the raccoon dog Nyctereutes procyonoides, and six samples of the American mink Neovison vison were studied using phenetic and craniometric methods. Analysis of the phenofund structure suggests that in all of the studied species the emergence of novel character variations does not lead to their fixation with a significant frequency. Considerable morphological variability emerges in the contact zone of different autochtonous populations, of wild and breeding forms, as well as in geographically and reproductively isolated small groups of individuals.

[Energy metabolism characteristics of various sections of the rat brain under the action of ethanol and lithium carbonate].

Acute alcohol intoxication (AAI, 2.5 g/kg intraperitoneally) was found to be followed by ATP level increase in all brain regions under study. As a result, creatinine kinase and ATPase activities were decreased.

[Pharmacological activity of cytochrome C].

Cytochrome C (a single dose range of 1-200 mg/kg, intraperitoneally) does not possess the antihypoxic activity (altitude chamber, methemoglobinemia, circulatory hypoxia), decreases (in a dose of 50 mg/kg) diuresis in rats modifying diversely (depending on the dose used) the hypnotic effects of general anesthetics and the convulsant activity of corazol and arecoline.

[Alteration of the acute toxicity and various pharmacologic effects of streptomycin sulfate by calcium 4'-phosphopantothenate].

The effect of calcium 4'-phosphopantothenate (CPP) on acute toxicity of streptomycin and the decrease by the antibiotic of the muscle working capacity, "holes" reflex, body temperature and oxygen intake was studied on 258 albino mice weighing 22-26 g. Medical calcium pantothenate (CPA) was used for control purposes. CPP is an antagonist of streptomycin sulfate.

[Change in the gastrointestinal tract and liver functions of animals due to dithiocarbamic acid derivatives].

The TMTD does not change the secretory activity of the dogs' stomach with its one-time administration by mouth in doses of 0.5--10 mg/kg. With its multiple introduction (10 mg per kg once a day for a space of consecutive 30 days) the secretion of juice increases, while the pepsin content in the juice of dags diminishes.
