    Abstract:
    The effect of 1,25-dihydroxyvitamin D3 (1,25-D) on the absorption of glucose in the small intestine was studied in five-sixths nephrectomized uremic rats and sham-operated rats. Four weeks after the nephrectomy, the uremic animals were divided into two groups: One group was given 1,25-D (300 pmol/kg body weight/day, three times per week) intraperitoneally, and the other was left untreated. One week after the 1,25-D treatment, an in vivo glucose absorption test was performed at 00.00 h in consideration of the circadian rhythm of glucose absorption. In untreated uremic rats, the glucose absorption rate was lower than in sham-operated rats. In 1,25-D treated uremic rats, the glucose absorption rate was higher than in untreated uremic rats and not lower than in sham-operated rats. These results suggest that the absorption rate of glucose of the small intestine is reduced in uremic rats and that it is recovered on treatment with 1,25-D.
