[Influence of occupational vibration on the female reproductive system and function].

The relevant literature on the effects of occupational vibration was analyzed in order to obtain information concerning a possibly health risk on the female reproductive organs Vibration exposure can probably contribute to the pathogenesis of disorders of female reproductive organs (decrease in uterine blood flow, menstrual disturbances, and anomalies of position) and disturbances of pregnancy (abortions, stillbirths). Experimental animal studies on the reproduction function suggest harmful effects on the fetus, and dystrophic and morphological changes in the uterus and ovaries in animals.

Study of homocysteine concentration in coronary heart disease patients and comparison of two determination methods.

Introduction: Elevated total homocysteine (tHCY) is a known risk factor for atherosclerotic vascular disease, but the mechanism is not well understood. The study was designed to estimate tHCY concentration and other risk factors in coronary heart disease (CHD) males, evaluating two different methods for tHCY measurement: gas chromatography-mass spectrometry (GC-MS) method and competitive immunoassay method.

Materials And Methods: Fifty men, mean age 53.

Effect of vibrations on male reproductive system and function.

From data in the literature, the potential risk of mechanical vibrations on reproduction in experimental, clinical and epidemiological studies (in experimental animals, men occupied in transport and industry), as well as the influence on sexuality are summarised. Results of the authors own experimental and clinical studies on the influence of the vibration on the male reproductive system are also presented. In male rats, decreased sperm counts, spermatogenesis index and size of testes, changed character of their motion, chronic venous stagnation and dystrophic alterations in tubuli contorti, changed ScDH, ATP-ase, LDH and GL-6-PDH activity, germ cells structural damages were observed.

Male reproductive function in workers exposed to vibration.

Male infertility is a significant health problem. Increasing attention has been paid to the use of semen analysis as an indicator of exposure to potential reproductive hazards. The aim of the current paper was to study the effects of vibrations on the spermatogenesis in workers of different occupational groups (professional drivers, miners, engine drivers, etc.
