Abstract
Oral admn. of KIO3 for a 2-day period in drinking water in non-fasted rats prevented the hyperglycemia which followed thiourea injn. The 12 rats in Group I receiving only thiourea showed an avg. rise in blood sugar of 91.0 mg. per 100 cc. 2.5 hrs. following injn. Rats in Group II which had been fed 0.2% KIO3 when injected with thiourea at the same dosage level as those in Group I showed an avg. blood sugar increase of only 14.6 mg. per 100 cc. Statistically the results are significant, the t-value of 5.16 indicating less than one chance in a thousand of the results being accidental.
