Abstract
Clinical effectiveness of porcine Calcitonin on bone diseases was proved in six cases of old aged patients; 4 fractures, multiple myeloma and osteoporosis. Calcitonin was administered 40 or 50 MRC U/day intramuscularly for about 40 days in each cases.
From the roentgenographic changings of 4 cases of fractures, it was suggested that calcitonin inhibited bone absorption and increased new-bone formation, because bone union was accelerated even in the cases of delayed union by calcitonin.
In a case of multiple myeloma or osteoporosis, positive roentgenographic changes were not observed, it might be of therapeutic value, because the patients were freed from pain by the administration of calcitonin.
