Ultrastructural change in the parathyroid gland of the phosphate treated newt, Triturus pyrrhogaster (Boié).
thyroid glands of the phosphate treated and hibernating (control) newts. The parenchymal cells of the newt parathyroid gland were classified into basal cells and suprabasal cells. Daily administration of phosphate caused no marked changes in the former cells. In the latter under experimental conditions, granular and agranular endoplasmic reticula and small dense granules seemed to be increased ...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولInduction of ocular tumor by nickel subsulfide in the Japanese common newt, Cynops pyrrhogaster.
Chemically induced ocular tumors in amphibians have not been reported previously. In the present study, nickel subsulfide (Ni3S2) was administered to lentectomized Japanese common newts, Cynops pyrrhogaster, by a single injection into the posterior chamber of the right eye (40-100 micrograms Ni3S2/newt). Control newts received a similar injection of vehicle. Malignant melanoma-like tumors devel...
متن کاملInduction of accessory limbs and of sarcoma in the Newt (Triturus viridescens) with carcinogenic substances.
Among adult vertebrates, only some of the amphibia are capable of regenerating their limbs. Several years ago experiments were begun in an attempt to induce neoplasia in limb tissues capable of such regeneration. The common newt, Triturus viridescens, was used because of its hardiness and availability. The injection of a variety of supposedly carcinogenic substances into the forelimb of over 50...
متن کاملInduction and differentiation of an epithelial tumour in the newt (Triturus cristatus).
W A D D I N G T O N (1935) and later Needham (1936) have suggested that the autonomy of tumours originates in a 'morphological escape' of tumour cells from the controlling influence of an individuation field which has locally become weak or has vanished. The persistence and strength of such an individuation field can be seen in its ability to induce its parts to regeneration (Ruben, 1955). This...
