ABSTRACT
The study was aimed to evaluate prevalence of osteopenia in miners engaged into deep-mined output of copper-zinc pyrite. The examinees were 130 males with clinical manifestations of bone and joint disorders, including 85 drifters engaged into underground mining (main group) and 45 individuals of surface occupations. Hazardous work conditions (4 degree of 3 class) cause in workers engaged into deep-mined output of copper-zinc pyrite risk of osteopenia that is more prevalent than in the surface occupations workers and is highly related with the occupation.

The specific features of dystrophic changes in the locomotor system of manual and intellectual laborers were studied on the basis of clinical and radiation diagnosis. The rate of dystrophic vertebral column lesions was approximately equal in both groups (38.5 +/- 4.8 and 37.7 +/- 6.7, respectively); however, the manifestations of sanogenetic reactions generally developed as hypertrophy upon exposure to chronic functional overstrain and as atrophy in intellectual laborers. Decompensation of the adaptive sanogenetic reactions manifesting as reflex, radicular, or myelogenous symptoms was observed in both occupational groups. The intellectual laborers more frequently underwent surgical treatment for complications of dystrophic vertebral column lesions.

The article presents results of neurophysiologic study of neuro-muscular disorders in skeletal and muscular diseases in oil industry workers. Findings are that intrasystemic relationships in nervous system of segmentary and suprasegmentary levels are involved into neuro-muscular disorders formation.

Experimental prednisolone administration has been shown to cause osteoporosis in animals. A single administration of fetal tissue--10-day fetal homogeneous tissue at a dose of 0.5 mg into the experimental animal femur improves the bone tissue structure, hastens its remodeling, contributes to elimination of the bone tissue pathologic process in osteoporosis.
