[Estimation of adaptive capacities in Magnitogorsk children from the activity of some detoxification enzymes].

The paper provides the first fragment of a multiparameter study analyzing the influence of environmental pollution, the social and psychological features of a family, and some endogenous factors on genome stability and sensitivity in a developed ferrous metallurgy town. It also gives data on the urine and serum activity of the lysosomal enzyme N-acetyl-b-D-glucosaminidase (NAG) and the serum activity of catalase in an organized contingent of apparently healthy children (n = 178; 6 kindergartens) aged 5-7 years, who live permanently in Magnitogorsk at different distances from the metallurgical works. More than 70% of children selected for examination were found to have average normal levels of activity of the enzymes studied.

[Products of the photolysis of 3,6-dichloropicolinic acid (the herbicide lontrel) in aqueous solutions].

We studied the composition of products of the photochemical degradation of 3,6-dichloropicolinic acid (DCPA), the active principle of Lontrel, a herbicide broadly used in agriculture. Ultraviolet irradiation (mimicking the natural sunlight action) did not degrade DCPA completely to environmentally safe products. The rate of DCPA degradation was notably lower when distilled water was replaced by river water and even lower in sea water.

[Screening for breast cancer in females at the level of regional (territorial, republican) clinical hospitals: organizational and methodological aspects].

The paper deals with a special screening for breast cancer in female visitors of the consultative-and-diagnostic units (CDU) of regional (territorial, republican) clinical hospitals in the Russian Federation. The study was conducted in the CDU of the Moscow Regional Clinical Research Institute that in addition to its clinical researches acts as a regional clinical hospital for the Moscow Region. The basic idea of this screening is firstly that specialists of such-level CDU attended by many women requiring various consultations obligatorily give multifaceted counseling.

[A place of outpatient screening in the formation of a current organizational scheme for better radical detection of breast cancer].

The authors consider it necessary to revise the current views of breast cancer in women. In their opinion, excessive consideration of mammography as an independent section of radiation diagnosis does not contribute to better detection of breast cancer. The principle of including mammography into the general traditional section of current radiation diagnosis should be regarded as of paramount importance.
