Research Abstract

Because ultrasound radiation alone did not ameliorate adipocyte dysfunction, we investigated the molecular target of frequently used drugs as the adjunct therapy. Pitavastatin enhanced adipocyte proliferation/ maturation, increased small adipocyte count, preserved adiponectin level, and improved insulin resistance ; pioglitazone suppressed a cell-cycle inhibiting factor and increased adipocyte count. Thus, therapeutic ultrasound with the adjunctive drugs would include cell-cycle inhibitors.
