Abstract
Anemia induced experimentally either by administration of phenylhydrazine or by splenectomy stimulated spermatogenic and steroidogenic activities in the testes of the toad (Bufo melanostictus). It is concluded that the stimulated activity of the testes is mediated through the hypothalamoβpituitary axis.

## Abstract Resting plasma epinephrine (E) and norepinephrine (N) concentrations for intact toads (__Bufo paracnemis__) were 5.57Β±1.0 and 0.88Β±0.38 ng/ml, respectively. Exercise induced a significant increase in heart rate, blood pressure and plasma epinephrine (about 4.3 times), whereas norepineph
The cardiodynamic consequences of dry season dormancy in ectothermic vertebrates is not well known. Our hypothesis was that dormancy would reduce cardiac activity. We therefore determined oxygen uptake and cardiovascular function in aestivating toads, Bufo paracnemis, native to SΓ£o Paulo State, Braz
