[The effect of dissimilar metals (galvanic current) on bone tissue status].
Effect of galvanic current of 16-20 microA on bone tissue compactness was studied by ultrasonic osteometry. For this purpose plates of different metal alloys (anode, CPC-250, cathode, an alloy of 9 parts of copper and 1 part of aluminum) were surgically implanted to rabbit tibial periosteum, the implanted plates generating the aforesaid galvanic current parameters. Significant differences in ultrasound propagation rates were observed at the sites of anode and cathode exposure in 3, 7, 15, 30, and 90 days after the onset of the experiments; these changes permitted a conclusion on differentiated effects of galvanic current on bone tissue function and compactness.
