ABSTRACT
[Objective] To investigate the renal histological parameters in SD rats and beagles and to supply evidence for renal toxicological and pathological diagnosis. [Methods] Forty SD adult rats and 20 adult beagles (half males and half females) , were respectively executed at 12 weeks and 12 months old. Then, kidney tissue was fixed in 10% neutral formalin, embedded in paraffin, made into slices at 5?m and stained by HE. The larger diameter and shorter diameter of glomerulus in the renal cortex and outer stripe of rats and beagles were determined by Spot Advanced image analysis software. The differences of the above parameters appearing in different species and genders were compared. [Results] The larger diameter was about 96 ?m, and the shorter diameter 76 ?m in the renal cortex of the beagles, and the larger was about 120?m and the shorter 94 ?m in the outer stripe of the beagles. The differences of the larger and shorter diameters were insignificant between the male and female beagles, but the larger and shorter diameters in the outer stripe were longer than those in the cortex. The larger diameter and shorter diameter were about 87 ?m and 64 ?m respectively in the renal cortex of SD rats, and the larger was about 88 ?m and the shorter 64 ?m in the outer stripe of SD rats. The differences of the larger and shorter diameters were insignificant between the male and female beagles, as well as in the outer stripe and the cortex. [Conclusion] The nephron in the outer stripe is larger than that in the cortex of beagles but no difference of the nephron exists in SD rats. The nephron in beagles is larger than that in SD rats, and there is no difference in the nephron between male and female beagles and SD rats.
