Intra peritoneal injection of 200 g Trout hold at + 12 degrees C with 2x10(8) p.f.u. of a new Rhabdovirus (strain 23.75) induces an interferon synthesis within 2 days. (IF titres reaching 2,000 units/ml). 1 month later, the surviving Fish exhibit a specific anti 23.75 neutralizing serum activity (titre 40 to 80) which has been demonstrated to be due to immunoglobulins. This seroneutralization is also recorded in 1/3 of the survivors of natural infection. 相似文献

Summary We studied the distribution of an immunoreactive substance resembling growth hormone-releasing factor (GRF) in the hypothalamus and pituitary gland of the rainbow trout by immunofluorescence methods. The GRF-like immunoreactive perikaryon was observed in colchicine-treated fish. The majority of GRF-containing neurons were located in the nucleus lateral tuberis; others were located in the caudal part of the preoptic nucleus of the hypothalamus. The GRF-like immunoreactive neuronal processes projected into the pars distalis via the pars nervosa of the pituitary gland. The distribution of the GRF-like immunoreactive substance in the hypothalamus and pituitary gland suggests that GRF plays a physiological role in the regulation of growth hormone release from the pituitary gland of rainbow trout, as it does in mammals. 相似文献

Summary The variations of glycogen, lipids and ashes in muscular tissue of the Rainbow trout (Salmo gairdnerii Rich.) show that during sexual cycle there are 4 periods. Each period corresponds to a particular biological activity. The sexual activity cannot explain all the modifications of glycogen content. 相似文献

Résumé Des doses variées d'insuline administrées à l'Ophicephalus striatus ont augmenté la quantité de glycogène du foie et des muscles. Dans le foie, les doses étant fortes (40 IU et 60 IU), la quantité normale de glycogène a presque quadruplé et elle a plus que septuplé dans les muscles. Le mécanisme possible présidant à l'action de l'insuline est aussi discuté. 相似文献

Summary The authors have noted, during the reproductive cycle of the Rainbow trout (Salmo gairdnerii Rich), important variations concerning water and total proteins content. This study shows a great correlation between the biological process and biochemical variations. 相似文献

We previously showed that the brown trout possesses UV-sensitive cones in its retina that are lost in 2-year-old fish. However, present investigations reveal that in the narrow growth zone along the periphery and the ventral embryonic fissure, the formation of these cones continues in trout and salmon. 相似文献

Summary InLaevicaulis alte maximal blood glucose level at 00.00 h alternates with minimal level at 12.00 h of the day, while hepatopancreatic glycogen showed an opposite trend. Variations in blood glucose levels are inversely proportional to the corresponding variations in hepatopancreatic glycogen content, while blood glucose level shoots up to a maximum, hepatopancreatic glycogen declines to a minimum and vice versa.Acknowledgment.

The histochemical study of the LDH in the Trout embryo during the early organogenesis shows a specific localization in notochord cells, in mesodermic cells of the terminal knob and in some prosencephalic neuroblasts. The role of the LDH in the metabolism of NAD as well as in the energetic metabolism of embryonic cells is discussed. 相似文献
