Cytochemical Studies on Liver Fibrosis

Cytochemical Studies on the Kidney

Determinations of the desoxyribonucleic acid (DNA) content of the kidneys of growing rats were made on the whole tissues and on isolated nuclei. It was found that the DNA content per nucleus is constant in rats of different weights. The DNA content of the kidneys increased proportionately to their mass over the range studied. It is concluded that increase in mass is primarily due to cell multip...

Cytochemical Studies on the Chicken Erythrocyte

Chicken erythrozytes possess many characteristics which make them a desirable material for experimental studies in cytochemistry, particularly those dealing with the chemical composition of various structural components within the cell. Avian erythrocytes have been used as a convenient source of material for the isolation of nuclei. Investigations along such lines were reported as early as 1869...

Cytochemical Studies of Mitochondria

1. Mitochondria isolated from rat liver were disrupted with 0.3 per cent deoxycholate and a number of subfractions were isolated from this preparation by differential centrifugation. 2. The protein N, RNA and phospholipide content, as well as the succinoxidase, cytochrome c oxidase, adenylate kinase, and DPNH-cytochrome c reductase of these fractions were determined. 3. Two of these subfraction...

THE EFFECT OF GLUTARALDEHYDE ON CATALASE Biochemical and Cytochemical Studies with Beef Liver Catalase and Rat Liver Peroxisomes

Peroxidatic activity of catalase (E .C .1 .11 .1 .6) was discovered by Keilin and Hartree (1), and it has been firmly established that, catalase oxidizes various substrates such as ethanol, methanol, nitrite, and formate (2-4) . Crystalline beef liver catalase, used as an enzyme tracer (5), and the peroxisomal catalase (6, 7) have been visualized cytochemically by a modification of the 3,3'diam...
