Different Tissues

Nucleic acid content in different tissues in the freshwater fish N.notopterus in relation to sex was studied during Pre-spawning phase of the reproductive cycle. The fish were scarified and the tissues such as brain, liver, kidney and gonads removed and processed for determination of nucleic acids. It is observed that the nucleic acid content in different tissues of female fish has lower values than males. The results obtained in the present study may provide a contribution to the knowledge of the characteristics of nucleic acid as parameters of sexing the fish. The study also indicates that although male fish have higher values than female fish, both the sexes are biochemically and nutritionally better.

Rna Concentration

The concentrations of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), in ovine uterine tissue were studied to determine whether the ratio RNA/DNA might be used in the bioassay of oestrogenic activity. As the uterus decreased in size with time after ovariectomy, the concentration of DNA increased markedly, but the total content of DNA in the uterus remained constant (mean value 342 ? 8 (SE) mg). The RNA concentration of the tissue decreased during involution, with the result that a highly significant reduction of 33% in the RNA/DNA ratio occurred within 2 weeks of ovariectomy. The ratio decreased further with time. Other ewes were treated for 3 days with diethylstilboestrol dipropionate (10 µg/day), commencing 2 weeks after ovariectomy; the stage of the oestrous cycle at which the ovaries were removed had no effect on the response to the oestrogen. Changes in the nucleic acid concentrations in the uteri of these ewes, and the results obtained during involution, indicate that the RNA/DNA ratio of uterine tissue in ovariectomized ewes has potential as a basis for the bioassay of materials of low oestrogenic potency.

Changes in� the nucleic acid content of the solid residue obtained by haemolysing the blood of mice infected with Plasmodium berghei have been examined. The residue from blood in which 25 per cent. of the red blood cells were parasitized contained 20-25 times as much ribosenucleic acid (RNA) and 12 times as much desoxyribosenucleic acid (DNA) as the residue from uninfected blood.

Nucleic acid content in brain, liver, kidney and gonads of the freshwater fish Notopterus notopterus collected from different aquatic bodies were studied during pre-spawning phase of the reproductive cycle. The three different aquatic bodies selected were Saradgi nala, Bennithora River and Bheema River and their physiochemical parameters also studied. The present study of nucleic acid content in brain, liver, kidney and gonads of the fish Notopterus notopterus collected from aquatic body Bennithora River shows normal levels of the nucleic acid as compared to that of fish from other two aquatic bodies. The normal content of nucleic acid content of N.notoptuers in the aquatic body Bennithora may be due to favorable environmental condition for survival, growth, distribution and reproductive activity.

The soluble proteins in five bloating and six nonbloating forages were separated chromatographically on agar gel columns and 18S protein, the agent causing bloat, was determined in column effluents. Bloating forages contained approximately one-third of total proteins in the form of 18S; nonbloating forages one-sixth or less. Total protein was highest in bloating forages. Nucleic acid content of the two types of forages was not significantly different. Production of nonbloating forage mixtures by mixing forages of high and low 18S protein is discussed.
