The level of thyrotropin (TSH) secretion is determined by the balance of TSH-releasing hormone (TRH) and thyroid hormones. However, neuromedin B (NB), a bombesin-like peptide, highly concentrated in the pituitary, has been postulated to be a tonic inhibitor of TSH secretion. We studied the pituitary-thyroid axis in adult male mice lacking NB receptor(More)
The objective of this study was to verify if the diet protein level affects the genesis of the repair tissue in rats submitted to a poly-chloro-vinyl (PVC) sponge implantation, as well as to analyse the possible alterations in the synthesis of the mucopolysaccharides acids (glucosaminoglycans) by the histophotometry technique.

Neuromedin B (NB), a neuropeptide highly concentrated in pituitary, has been proposed to be an inhibitor of thyrotropin (TSH) secretion. Previous study showed that mice with disruption of neuromedin B receptor (NBR-KO) have higher TSH release in response to thyrotropin-releasing hormone (TRH), although TSH seems to have decreased bioactivity. Here we(More)
