Interrelation of cerebral vessels reactivity and state of central afferent inductive structures at chronic mercury intoxication

The following groups were examined under clinical condition: the 1st group (47 persons) - the employees with a long work period working at the Joint-Stock Company "Sayanskchimplast" exposed to mercury compound. The mean age - 49,2 ± 4,4 years old, the mean working period -18,1 ± 5,6 years....
