[Working conditions and functional state of the organism of mechaniciandrivers under the defoliation of the cotton-plants].

In the article there are presented results of the study of the impact of working of mechanicians-drivers performing cotton-plant defoliation with a new import-substituting low-toxic defoliant denoted as «Fandef-Alo» on a functional state of various systems of the organism. Working conditions and the character of labor processes under the execution of defoliation were revealed to give rise in adverse shifts of physiological responses of various systems of the organism in mechanician-drivers, and the noise and the overwork labor process elevate the probability for the risk of the occurrence of occupational diseases that is indicates to the need for measures for the making labor healthy.

[Environmental protection and health of the population at using of a new cotton defoliant «uzdef-k» in agriculture].

Toxicity parameters of a new cotton defoliant «UzDEF-K» were studied in various ways of exposure. The preparation is established to be referred to the IV hazard class. Hygienic standards of a defoliant in environment objects andfoodstuffs (maximum concentration limit in reservoir’s water - 2,0 mg/l, in working zone air - 2,5 mg/m and atmospheric ambient air - 0,2 mg/m were set).

[Criteria for standardizing the density of building and population of developmental lands of cities].

The paper presents hygienically substantiated ways of regulating the reconstruction and concentration of houses and plots near them in particular, which makes it possible to preserve the minimum required set of functional zones of the near-house territories, to improve the environmental situation, microclimatic and noisy conditions, and the population's living conditions when urban lands are intensively used.

A large outbreak of poliomyelitis following temporary cessation of vaccination in Samarkand, Uzbekistan, 1993-1994.

Oral poliovirus vaccine (OPV) was not available in Samarkand, Uzbekistan, from November 1992 to August 1993. The ensuing outbreak of poliomyelitis was investigated: Patients with poliomyelitis were evaluated, the extent of poliovirus circulation was estimated, and the effectiveness of control measures was assessed. Between March 1993 and April 1994, 74 cases of paralytic disease attributable to poliovirus type 3 were reported.

[Daily energy expenditures of Uzbekistan miners].

Daily energy expenditures of miners in Uzbekistan were determined: 4076-4372 kCal. These data can be used for development of rations for Uzbekistan miners.
