| Research Abstract |
We hypothesized that the calcitonin plays an important role in the liver regeneration after hepatectomy. The mean level of CGRP gene in the remnant liver was rapidly increased at 1h after hepatectomy and this overexpression of CGRP gene persisted still 12h after hepatectomy. In the immunohistochemistry, there were many droplets in hepatocytes of 12h after hepatectomy. The serum CGRP level was significantly higher at 12h after hepatectomy, and as correlate with this, the serum calcium level was significantly lower at 12h after hepatectomy. In animal experiment used with the CGRP antagonist, the liver regeneration rate after 70% hepatectomy was significantly decreased in the CGRP group.
