[Toxicological and hygienic evaluation of a new fodder additive: liquid mash concentrate]. / Toksikologo-gigienicheskaia otsenka novoi kormovoi dobavki-- kontsentrata bardianogo zhidkogo.

The results of toxicological evaluation of 'concentrate bardjanoj liquid' (CBL) a new fodder additive are presented. It was shown on one generation of rats that CBL at dose of 1 g and 10 g per 1 kg of body mass had no an embryotoxic, gonadotoxic and teratogenic effects. However long-term intake of CBL during 5 month with diet of rats caused the changes in rat body. It was found increasing of relative weights of kidney, spleen and heart, decreasing of contents of total lipids, phospholipids and cholesterol in rat liver. Also the desquamative enteritis in some cases with ulcers was found. These data did not allow to recommend CBL as fodder additive in studied doses.

These changes are dose-dependent and most manifest when haprin comprised 50% of the total protein content in the ration.

[Paraffin treatment of garlic for long-term preservation]. / K voprosu o parafinirovanii chesnoka dlia ego dlitel'nogo khraneniia.

The optimal conditions have been developed for garlic preservation by its treatment with a mixture of food paraffin and monoglyceride in the ratio of 95:5 at 80 degrees C, followed by the storage at 0-1 degrees C, and relative humidity 65-75%. When garlic is treated with plasticized paraffin, the main hydrocarbon components of paraffin - n-alkanes C20-C31 are accumulated in its pulp. Monocyclic aromatic hydrocarbons are practically absent in food paraffin and paraffined garlic. The quantitative parameters of the paraffined garlic characterizing high technological and economic effectiveness of the method, as well as insignificant increase in the p-alkanes content (1%) in the daily ration for humans, that contains paraffined garlic, have permitted the authors to recommend this method of garlic storage for using under industrial conditions, the technological regulations should be strictly kept to.

[Safety of animal husbandry products produced by using allyl isothiocyanate-preserved feeds]. / Izuchenie bezvrednosti producktov zhivotnovodstva, poluchennykh pri ispol'zovanii kormov, konservirovannykh allilizotiotsianatom.

To examine the safety of foods (meat and milk) obtained from animals whose feeds were preserved with allyl isothiocyanate (AITC), the authors investigated the status and development of animals, some aspects of protein, lipid and carbohydrate metabolism, some enzymes, hemopoiesis and reproduction function of Wistar rats fed diets containing the above products (55 g dry milk or 50 g boiled meat per 100 g diet). To measure the residual quantity of allylamine (AA), the main metabolite of AITC, a chromato-fluorometric method with the use of dansyl chloride was devised, permitting the detection of 2 ng AA in the spot. The relative standard deviation was 0.14-17. The degree of AA extraction amounted to 96%. The method made it possible to detect the residual quantity of AA in the kidneys (up to 12.2 +/- 2.0 micrograms/kg) and in the liver (up to 83.1 +/- 12.4 micrograms/kg). The data obtained evidence that AA cannot be used as conservant for manufacturing feeds for agricultural animals.

[Carbohydrates of the chicken egg yolk]. / Uglevodorody zheltka kurinykh iaits.

In the yolk of the eggs of hens receiving traditional feeding hydrocarbon mixtures contained in trace amounts therein were analyzed by a specially elaborated method. For identification and quantification the data of the gas liquid chromatography, chromato-mass-spectrometry and ultraviolet spectrophometry were used. In a complex hydrocarbon mixture chromato-mass-spectrometry helped identify the alkanes of the normal and isoprenoid structure, cycloalkanes, of terpene and sterene types. The alkanes and cycloalkanes fraction content was found to comprise 15-30 per 1 mg of the raw mass of the yolk, of the p-alkanes--1-3 mg, squalene--15-17 mg and of monocyclic arenes--about 1 mg.

[Method of isolating, identifying and quantitatively determining alkanes, cycloalkanes, monocyclic arenes and squalene in animal organs and tissues]. / Metod vydeleniia, identifikatsii i kolichestvennogo opredeleniia alkanov, tsikloalkanov, monotsiklicheskikh arenov i skvalena v organakh i tkaniakh zhivotnykh.

A method for analyzing hydrocarbons in animal organs and tissues has been developed. This is made up of the following stages: decomposition of the biological material through alkaline hydrolysis; extraction of non-saponifiable lipids fraction; separation by using preparative thin-layer chromatography of the alkanes and cycloalkanes, monocylic arenes and squalene from the non-saponifiable lipids fractions; determining the content of the alkanes and cycloakanes fraction and also ascertaining the alkanes of normal and isoprenoid structure, by means of gas-liquid chromatography, and, finally, quantification of monocyclic arenes, based on the UV spectra findings. The statistical characteristics obtained through a mathematical processing of the analyses results bear evidence to a sufficient accuracy and good reproducibility of the method stages.
