Histophysiology of the Obesity-Diabetes Syndrome in Sand Rats [Paperback]

The book gives a review of the state-of-the-art of recent investigations of the adipositas diabetes syndrome of sand rats kept under laboratory conditions and given various diet regimes. Measurements of specific activities and flux rates in carbohydrate and fat metabolism determined by different analytical methods in vitro and in vivo provide insights into the pathophysiology and pathobiochemistry of different forms of the diabetic syndrome which cannot be obtained in humans.The book gives a review of the state-of-the-art of recent investigations of the adipositas diabetes syndrome of sand rats kept under laboratory conditions and given various diet regimes.
