    ABSTRACT: A novel approach to carbon-13 (13C) enrichment of chloroplast membranes (and plant materials in general) is presented for 13C-nuclear magnetic resonance (13C-NMR) studies. The method minimizes the occurrence of spectral complications arising from 13C-13C couplings resulting from a statistical distribution of 13C within the molecule with low probability of encountering two 13C atoms adjacent to each other. This is achieved by growing the plants in light surrounded by an atmosphere containing 1/3rd 12CO2 and 2/3rd 13CO2, liberated by weak acid-treatment of a mixture of corresponding barium carbonate salts.

    ABSTRACT: Retinae and pecten oculi of chickens were studied after 30 days of dark and light adaptation. Biochemically, glycogen and alkaline phosphatase activity increased 24 and 6%, respectively, in retina on dark adaptation, and decreased 15 and 17%, respectively, on light adaptation. Retinal RNA content increased 11% on light adaptation. DNA remained unaffected on dark and light adaptation of the retina. Alkaline phosphatase activity of pecten decreased 25% on dark adaptation.Histochemically, glycogen-rich paraboloids of accessory cones and hyperboloids of rods of the retina atrophied when subjected to light and hypertrophied on dark adaptation. On light adaptation, except for the outer plexiform layer, the alkaline phosphatase activity was negligible. Possible significance of these results in relation to sensory functions of the retina and retina-pecten interrelationship is discussed.

    ABSTRACT: Chickens were adapted to dark and light for 30 days and their retinas were studied in comparison to the chickens kept in normal environments. Total phospholipid content and cholinesterase activity were determined biochemically in the retinas of each group of animals. An increase of approximately 22% was observed in the phospholipid content of the dark adapted retinas, whereas the light adapted retinas showed no significant change in comparison with the normal counterparts. Retinal cholinesterase activity decreases by about 64% on dark adaptation and increases by about 14% on light adaptation.

    ABSTRACT: S. R. Bawa and Rakesh C. Yashroy (1971) Effect of Gamma Irradiation on the Chicken Retina. Radiation Research: November 1971, Vol. 48, No. 2, pp. 303-311. Effect of Gamma Irradiation on the Chicken Retina S. R. Bawa and Rakesh C. Yashroy Chickens were irradiated in the head region with an exposure of 2000 R. The retinae were removed and studied 30 days after irradiation. Phospholipids, proteolipids, ribonucleic acid (RNA), deoxyribonucleic acid (DNA), acid phosphatase, and acetylcholinesterase (AChE) were analyzed biochemically. Phospholipids and alkaline phosphatase showed marked increase whereas acid phosphatase, AChE, RNA, and DNA declined. Histochemically, sudanophilia and glycogen increased appreciably.
