To examine the effect of high dose vitamin D3 treatment on visceral adipose tissue, we used vitamin D deficient male Wistar rats (18 months old) as a model of sarcopenia. The aging process is not only responsive for the losing muscle mass but also for redistribution of lipid resulting in altered fatty acid storage and dysdifferentiation of mesenchymal precursors. The effect of aging and vitamin D treatment (weekly oral gavage with 0.125 mg vitamin D3 (5000 IU)/100g body weight) on the omental adipose tissue were histological examinated. At the end of the experiment (9 monhs), adaptive changes to the reduction of adipogenesis and increased apoptosis in response to long-term treatment with vitamin D consisted of smaller size of adipocyte and moderate macrophage infiltrate.
