Diabetic and healthy rats fed with high iron diet plus capsaicin.

p value from paired Student t-test at the beginning and at the end of intervention. The dose of capsaicin used was 1 mg/kg body weight/day administered subcutaneously. Initial refers to values before intervention. Final refers to values after 4 weeks of intervention. To confirm the effects of diabetes on hemoglobin in the high-iron group, an additional group of seven rats were tested; those data have been added £n = 17. The paired Student t-test was calculated with the lower n indicated at the top of the Table. In diabetic rats plus capsaicin the differences between initial and final values corresponds to death of one rat. In healthy rats with high iron the missing values at the beginning were due to technical difficulties in the measurements.
