Effect of diet on the kidney morphology of lactating dam and virgin rats. Kidneys were obtained from dams (D) or virgin (V) rats fed a glucose (G), fructose (F), or starch (S) diet for 6 wk. A) Kidney somatic index. Bars are means ± se; n=5–8. Differences (P<0.05) among means are indicated by differences in superscript letters, as analyzed by 1-way ANOVA LSD after an initial 2-way ANOVA showed diet effects. B) Hematoxylin-and-eosin staining of a transverse section at the longest point of the right kidney of a rat representing each diet group. Length (horizontal arrow with grid) and width (vertical arrow) of the VS kidney were determined initially, and then the same-sized arrows superimposed on the sections were obtained from DG, DF, DS, VG, and VF rats, to depict differences in size. Results indicate that the representative, randomly chosen VS kidney is smaller than those of dams, particularly that of dams fed fructose.
