Hormone control in regeneration: effects of somatostatin on appendage regeneration, blood glucose and liver glycogen in Diemictylus viridescens
In the present communication, synthetic somatostatin, a hypothalamic factor which has a known inhibitory effect on the release of growth hormone, thyroid-stimulating hormone, prolactin, insulin and glucagon in man and other mammals, was found to have an inhibitory effect on limb and tail regeneration in adult Diemictylus viridescens, when the newts were treated with a daily dose of 3-5 or 15 /^...

متن کاملThe relationship between the anterior pituitary gland and the pancreas in tail regeneration of the adult newt.
Histological examination of the amputated tails of 17 hypophysectomized newts revealed abnormal and extremely retarded regenerates; four of them exhibited total inhibition of regeneration. Thus, under the conditions of hypophysectomy, normal tail regeneration does not ensue in the adult Diemictylus viridescens. Also, hypophysectomy adversely affects the normal histology of both the endocrine an...
متن کاملA Comparison between Granulomatosis and Lymphoreticular Neoplasia in Diemictylus viridescens and Xenopus laevis1
Stocks of Xenopus laevis which have been used recently to generate lymphoreticular neoplasia (L-1) have apparently become infected with pathogenic acid-fast bacteria. These materials provided us with an unusual opportunity to com pare a granulomatous response with this lymphoreticular neoplasm of the histiocytic type in both newt and Xenopus hosts. The granuloma foci were found to differ from t...
