Nucleolar changes in maturing avian erythroblasts and erythrocytes.

abstract：:Pituitaries from normal, young and adult male rats were fixed either in sublimate-formalin or in glutaraldehyde-osmium. In adjacent Paraplast sections, almost all the gonadotrophs were immunostained with both LH and FSH antisera. The rat LH beta and FSH antisera used were shown to be highly specific by the absorption ...
