LH-RH neuron system of the newt by immunohistochemical study.

The location of LH-RH producing neurons, the pathways and terminal distributions of their fibers in the newt, Cynops pyrrhogaster were studied immunohistochemically. The LH-RH positive perikarya are located in the nucleus of the diagonal band of Broca and the medial septal nucleus. No LH-RH immunoreactive neuronal perikarya could be detected in the diencephalon. The pathways of fibers originating from the LH-RH reactive neurons were classified into three groups: the first project to the median eminence, the second to the olfactory bulb and the third to the habenular nucleus. The latter two pathways are extrahypothalamic, similar to those in mammals. These observations are briefly discussed and compared with those in other amphibian and mammalian species.

Light chains of chicken embryonic gizzard myosin.

1. Myosin from gizzards of 15-day-old chicken embryos was highly purified by ammonium sulfate fractionation in the presence of ATP and MgCl2, ultra-centrifugation and Sepharose 4B chromatography. 2. The myosin composed of heavy and three light chains as determined by sodium dodecyl sulfate (SDS) gel electrophoresis. The molecular weights of the light chains were 23,000 (L23), 20,000 (L20), and 17,000 (L17), respectively. The amount of L23 light chain decreased and disappeared, and the L17 light chain increased steadily in the course of development. The amount of L20 light chain did not change. 3. ATPase activity of the embryonic myosin was essentially the same as that of adult myosin. The change in the light chain pattern in the course of development did not correlate to the ATPase activity. 4. Antigenicity of the heavy chains in the embryonic myosin was the same as that of the adult heavy chains. However, antibodies to light chains were not detected in the antibodies to either the embryonic or adult myosins.
