Outstanding German researches of mountains of Kazakhstan

Annotation: Activity of German scientists who explored mountain systems of Kazakhstan and Russia is considered in
the article. Scientific biographies of P.S. Pallas and H. Merzbacher is presented.

Anthelmintic preparations that cause side effects in children

Annotation: Today the clinical manifestation of enterobiosis is studied adequately. However, global environmental
changes for the last decades, the widespread use of anthelmintic preparations, medications and number of
other factors have changed the clinical data of parasitic infestations. Today a question of treatment of parasitic
infestationsof children is not fully resolved. Despite the availability of a wide range of antiparasitic agents,
they possess a lot of side effects. Moreover, currently, there is a tendency that many parasites develop
tolerance for antiparasitic preparations.
In this regard search methods for early, highly-qualified, informative and specific verification
of helminth-parasitic infestation remain relevant in order tocarry out timely treatment with the methods, which
have minimal side effects and possess high efficacy against parasitic infections of children.

Rare species of reptiles of the Nakhchivan Autonomous Republic

Annotation: Based on the analysis of own and literature data 9 numerically insignificant species of reptiles were found at the territory of the autonomous republic. One of these species belongs to a group of turtles (Testudines), three of them belong to a group of lizards (Sauria) and five of them belong to a group snakes (Serpentes). Systematics, ecological and some biological peculiarities of species are reflected in the article. During the research previously registered Psammophis lineolatus has not been found and its existence at the territory of the Nakhichevan Autonomous Republic is under question.

Тhe species composition and nutrition of dominant f

Annotation: The results of analysis of catches with stationary nets made from 2010 to 2012 in the North Absheron Gulf of the Caspian Sea have been presented. 26 species of fish belonging to 8 families (16 marine species, 10 migratory and semi-migratory species ) is registered in the catches. There are data distribution and abundance of each species for all of the families are summarized. The tendency of expansion of areals of marine species (Alosa braschnikowi kisselewitschi, A.b.sarensis) to the north is registered.
