Hyperhomocysteinemia-Induced Vascular Damage in the Minipig

Abstract

In minipigs, the present methionine-rich caseinate-based diet induced hyperhomocysteinemia, which reproduces the metabolic and histopathological situation found in homocysteic patients. Our results show that hyperhomocysteinemia-induced vascular alterations favor the viscous component of the wall rheology to the detriment of the elastic component. Furthermore, they extend to hyperhomocysteinemia the therapeutic effects characteristically shared by ACE inhibitors in association with hydrochlorothiazide against the atherogenic activation of elastinolytic processes.
