  • Title: [Characteristics of the carbohydrate digestive transport carrier in rats exposed to the effect of a temperature factor in early postnatal ontogeny].
    Author: Rakhimov KR, Sadykov BA.
    Journal: Zh Evol Biokhim Fiziol; 1984; 20(3):277-81. PubMed ID: 6741350.
    Abstract:
    Using accumulating preparations of the small intestine mucose, studies have been made of the initial stages of glucose uptake from solutions of glucose, maltose and starch in rat puppies at the age of 17, 24, 31 and 38 days, which were subjected from the 10th to the 17th day of postnatal life to daily heating (up to 40-41 degrees C) or cooling (up to 6-7 degrees C) for 2 hours. It was found that in heat-adapted animals, the rate of accumulation of "free" glucose remained the same as in control animals, whereas the rate of uptake of the glucose in the form of maltose or starch was significantly decreased. Cold adaptation promoted stable stimulation of carbohydrate hydrolysis and transport functions of the intestine.
