BHE and Wistar rats fed SP 8 HVO and SPE 

 diets. The kidneys were generally small even 

 with SPE diet, in marked contrast to the large 

 kidneys from comparable BHE rats. Kidneys 



from only two rats of the Wistar strain exceeded 

 4 grams, one from a rat fed SP 8 HVO diet and 

 one fed SPE diet. For both diets, livers tended 

 to be smaller in Wistar than in comparable BHE
