Ultrastructural studies on mitochondrial swelling.
Mitochondrial swelling induced by valinomycin, calcium chloride and P(i) was studied after potassium permanganate fixation in suspension. Valinomycin induces a rapid K(+) influx, increase of the matrix space and out-folding of the cristae, with good preservation of the matrix material. This swelling is reversible but the cristae do not completely re-form and have a blebbed appearance. On repeat...
متن کاملComparative biochemical and biophysical studies on rat brain synaptosomes.
1. Introduction tosomal fractions was also checked by electron microscopy. Synaptosome isolation methods should meet two principal but contradicting requirements: The fraction should be enriched as much as possible in synap tosomes, while the amount of time used during the isolation process should be as short as possible. The conditions of synaptosomal preparation and the duration of each step ...
متن کاملBiochemical Studies on the Dystrophic Rat Retina and Brain
Evidence for the release of lysosomal enzymes was recently obtained in cytochemical and biochemical studies by Burden et al. (1971) and Yates et al. (1974). Increases in both total and free acid protease activity above those found in the normal retina were first observed in the affected retina at 4 weeks. These differences became more apparent as degeneration progressed. The stability of lysoso...
متن کاملPhytotoxicity of Profenofos 50% Ec (curacron 50 Ec) to Vigna Radiata, L. Seedlings: Ii. Studies on Biochemical Parameters
Profenofos 50% EC (curacron 50 EC) is a hazardous pesticide commonly used in agriculture is also an important contaminant of environment. Its presence in biological system has gained importance due to bioaccumulation in food chain. The phyto-toxic effect of profenofos was assessed based on the biochemical parameters (Shoot and Root) of seedlings (Amino acids, Protein, Sugar, DNA and RNA) of the...
متن کاملBiochemical Studies on Shock
During and following the production of shock by hemorrhage in the normal, suprareno-demedullated, and suprarenalectomized rat, the following significant changes in amino acid and carbohydrate metabolism have been observed. 1. In the intact, suprareno-demedullated, and suprarenalectomized rat there is a progressive rise in the whole blood and plasma amino acid nitrogen levels during and after a ...
