Investigations were conducted in late June to early June 2013. The population density of mollusks of the genus Juga in the shoreline and littoral covered by meadow waters was 10 to 30 specimens/m2; there were solitary specimens of the genus Parafossarulus. Fourteen out of 39 fish species were invaded by metacercariae of Clonorchis. Manchurian spiny loaches (Leptobotia) and Light's bitterling (Rhodeus lighti) are first registered to be hosts of Clonorchis. The metacercariae of Metagonimus yokogawai were detected in silver carp (Hypophthalmichthys molitrix) and those of Nanophyetus salmincola schikhobalowi were in the kidneys, fin muscles, and gills of taimen (Hucho) and lenok (Brachymystax lenok) from the Khor River. The invasion rate for the taimen was greater than 1000 metacercariae and that for the lenok was not more than 720 metacercariae per fish.

NMR studies of carbohydrate composition of several varieties of honey and surface layer of Altai honey were carried out. Investigated samples were differing by their geobotanical nature, year of collection and thermal effect to which they were subjected. It is shown that compared with honey its surface layer is enriched with glucose while fructose is depleted. It is established that fructose diastereoisomers in honey are in equilibrium concentrations, so their distribution does not change at heating. The effect of temperature on the ratio of alpha-/beta-form glucose in honey was established. It has been shown that in the unheated honey the value of the ratio alpha-/beta-glucose was > 1, when honey was heating glucose anomerization occured and due to this the ratio value became < 1. Therefore, the ratio of glucose anomers in honey can be considered as an index of its thermal transformation and can be used as an additional technique at examining the honey quality.

Balneological and experimental examinations were made of physiological properties of carbonate iron mineral waters of the Primorskiy Territory. The waters were found perspective as a source of ecologically healthy water, to prevent diseases, to raise nonspecific resistance of the body.

Experimental alimentary obesity was treated with hydrocarbonate magnesium-calcium water from Shmakovskoe deposit and hydrocarbonate-chloride sodium arsenous boric iodine-bromine water from springs in Sinegorsk. The study of lipid and carbohydrate metabolism proved the ability of the waters to prevent complex metabolic disorders typical for obesity.
