Noninvasive metabolic syndrome model using an extremely small minipig, the microminipig.

Abstract:

:Metabolic syndrome (MetS) induces serious complications; therefore, we developed a noninvasive MetS model using an extremely small minipig, the Microminipig. For 8 weeks, Microminipigs were administrated a high-fat and high-cholesterol diet (HFCD) for atherosclerosis and N(G)-nitro-l-arginine methyl ester (l-NAME) for inhibiting nitric oxide synthase. HFCD significantly increased serum low-density lipoprotein levels, l-NAME increased blood pressure and cardiac hypertrophy, and HFCD-induced aortal arteriosclerosis was accelerated by l-NAME administration. Endothelium-dependent relaxation of the coronary artery was remarkably decreased by l-NAME administration. This model may be useful for elucidating the mechanisms of MetS and developing new therapeutic medicines for its treatment.
