Pituitary growth hormone and hypothalamic somatostatin in young female rats versus old constant estrous female rats

Pituitary content and concentration of growth hormone was significantly reduced, and hypothalamic somatostatin content significantly increased, in old constant estrous as compared to young female rats. Increased levels of somatostatin may contribute to the decrease in pituitary growth hormone levels in these animals.     

Bilateral resection of superficial rat kidney cortex: Effect on sodium balance

Cellular and Molecular Life Sciences - Bilateral resection of the whole superficial kidney cortex (approximately 75% of glomeruli) was carried out in rats. These animals needed some 2 days longer...     

Albrecht von Haller on academies and the advancement of science: the case of Göttingen

This article approaches eighteenth-century views on scientific academies by examining Haller's utterances, public and private, especially those occasioned by the founding of the Göttingen Society. It deals in turn with his understanding of the distinctive purpose of academies, with his explanation of the chief ways in which they realized this end, with his thoughts on their broader usefulness, and finally with his various reasons for considering close ties with the state to be essential to their productive and harmonious operations.     

Lack of immunological specificity of heterologous so-called antilymphocyte serum

Zusammenfassung Thymozyten-Agglutinations- und Zytotoxizitäts-Titer von Kaninchenantiseren gegen Rattenthymozyten sanken nach erschöpfender Absorption mit Nieren- oder/und Leberzellen oder/und Organperfusionen stufenweise bis etwa 11 ab. Suspendierte Makrophagen, Thyreoidea-, Hoden- oder Ovarialzellen von Ratten wurden nach Inkubation mit diesen Antiseren fast ebenso rasch abgetötet wie Thymozyten.     

Pituitary growth hormone and hypothalamic somatostatin in young female rats versus old constant estrous female rats

Summary Pituitary content and concentration of growth hormone was significantly reduced, and hypothalamic somatostatin content significantly increased, in old constant estrous as compared to young female rats. Increased levels of somatostatin may contribute to the decrease in pituitary growth hormone levels in these animals.This work was supported by NIH Research grants AG-00416 (J.M.) from the National Institute on Aging, AM-04784 (J.M.) from the NIAMDD, and NIA postdoctoral fellowships AG-05208 (L.J.F.) and AG-05147 (W.E.S.).     

Bilateral resection of superficial rat kidney cortex: effect on sodium balance.

Bilateral resection of the whole superficial kidney cortex (approximately 75% of glomeruli) was carried out in rats. These animals needed some 2 days longer to restore their sodium balance when placed from low to high sodium intake in comparison with rats subjected to other types of partial nephrectomy.
