169 Abstract Two proteinous compounds (A and B) were isolated by gel filtration chromatography of the acetone precipitate of the aqueous extract of Portulaca oleracea L. plant. Comparative apparent molecular weights determination by gel filtration using standard proteins gave a value of 28184 and 2291 dalton respectively.The effect of the isolated proteinous compounds A , B and the hormone of i...

The objective was to study the regulation of glycogenolytic enzyme mRNAs in porcine satellite cells during proliferation and differentiation. Beyond 80% confluence, cells were grown in absence or presence of 1μM insulin. The observed increases in abundance of mRNA for glycogenin, glycogen synthase, phosphorylase kinase, phosphorylase and glycogen debranching enzyme, and no alterations of the tr...

Sarcoplasmic vesicles and ~-glycogen particles 30-40 m# in diameter were isolated from perfused rabbit skeletal muscle by the differential precipitation-centrifugation method. This microsomal fraction was subjected to zonal centrifugation on buffered sucrose gradients, in a B X I V Anderson type rotor, for 15 hr at 45,000 rpm in order to separate the two cytoplasmic organelles. Zonal profiles o...

oral supplementation with potassium bromide (10, 20 and 40 ?g/ml) to fifth instar larvae of csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori resulted in a significant increase in the fat body glycogen in all the treated groups and in all the three races of the silkworm, b. mori. the fat body protein content was increased with 20 and 40 ?g/ml treated groups in csr2 and csr4...

The fermentation of yeast reserve carbohydrates, glycogen and trehalose is a procedure to increase protein level of yeast cells and improve ethanol production. This work studied on the degradation kinetics of glycogen and trehalose carried out with two industrial strains of Saccharomyces cerevisiae (PE-2 and SA-1) and the effect of different temperatures (38o, 40o, 42o and 44oC) on degradation ...

The present study is designed to study the effect of a new heterocyclic compound on glycogen, pyruvate and lactic acid contents in tissues to understand the carbohydrate metabolism and its role in male rats. The treatment with ethyl -1 -(5 –chloro -2 –oxoindolin -3 ylideneamino) -1,2,3,6 –tetrahydro 4 -methyl -2 -oxo -6 –phenyl pyrimidine -5 -carboxylate compound at dose level of 3 mg/kg/b.wt. ...

In t rami tochondr ia l granules or bodies have been described by many investigators in various cell types. Al though the advanced techniques of electron microscopy in general have clarified the existence of several types of in t rami tochondr ia l components , and in some cases even their chemical characteristics (1, 2), the chemical na ture of most such substances is still unknown. Dur ing th...

Certain of the metabolic events associated with anaerobic sodium transport by the isolated bladder of the fresh water turtle have been investigated. The data suggest that energy for this transport arises from glycolysis and that endogenous glycogen was the major and perhaps the sole source of substrate. The rate of anaerobic glycolysis, as determined by lactate formation, correlates well with t...

the present study is related to the histochemical investigations on the changes in the intensity of reactions of axons, acid and neutral mucopolysaccharides, biologically active macromolecules, particularly glycogen and protein component as well as alkaline phosphatase (alpase) and adenosine triphosphatase (atpase) in the cells lining the olfactory epithelium of catla catla . the intense reacti...

The exposure of humans to fluorine is connected with its presence in the air, food and water. It well known that fluorides even at a low concentration but long time accumulate body lead numerous metabolic disorders. Fluoride recognised as factor modulating energy metabolism cells. This interaction particular importance muscle cells, which are cells high activity related glucose glycogen. In som...
