The Electrical Conductivity of Bone Marrow Cells Suspension Associated with Proliferative Activity and Depends on the Donor's Age and the Functional Activity of the Liver.

Copper ions play various roles in mammalian cells. Some investigations indicated that copper correlates with liver fibrosis and changes in bone marrow cells. Here, we explored the role of bone marrow cell parameters in copper liver fibrosis development and possible underlying mechanisms. The age-related features of biochemical indicators, bone marrow cell parameters, and electrical conductivity of 3- and 20-month-old male Wistar rats treated with copper II sulfate pentahydrate (CuSO4 × 5H2O) have been investigated. Based on the obtained earlier experimentally data in our laboratory, dose of 1 mg/100 g (0.58 mg/g of liver) was used. Induced liver fibrosis caused a change in the number and ratio of morphotypes of bone marrow cells, calcium and copper content, redox-system activity. These parameters depended of animals' age and presence of liver fibrosis. We also demonstrated that electrical conductivity can be used as integral parameter. In conclusion, the "adaptive response" modifies the emerging reactions of the organism to new external factors.
