Design and Method We divided forty mature female Sprague-Dawley rats SD into five groups of eight. SD ingested regular rat chow containing added sucrose 20 w w . The groups received baseline diet alone control or baseline diet containing captopril niacin-bound chromium maitake fraction SX or maitake fraction D. In addition to blood pressure readings the following procedures were implemented losartan and insulin challenges evaluation of serum ACE activity glucose tolerance testing blood chemistries LNAME challenge and measurement of various circulating cytokines. Results We found that .
