Distribution of phosphorus compounds in blowfly thoracic muscle.

Fiske and Subbarow (6) in their method of determination of phosphocreatine extracted the muscle tissue with trichloracetic acid in the cold and effected a separa1;ion of the phosphorus compounds by means of precipitation with an alkaline solution

The Influence of Fasting, Epinephrine, and Insulin 05 the Distribution of Acid-soluble Phosphorus in the Liver of Rats*

The normal distribution of phosphorus compounds in the liver and changes of these compounds in different conditions have been little studied. Cori and Goltz (1) described an increase of the inorganic P and easily hydrolyzable organic P fractions in the livers of mice consequent to the administration of insulin. In animals subjected to various experimental procedures, Flock and her coworkers (2)...

Interaction of Ca2+ with blowfly flight muscle mitochondria.

Blowfly flight muscle mitochondria differ markedly from mammalian mitochondria in their interaction with Ca2+. State 4 respiration of blowfly mitochondria is not stimulated by Ca2+, nor does Ca*+ induce a reversible shift in the oxidation-reduction state of cytochrome b. Nevertheless, CaZf is accumulated by respiring blowfly mitochondria, but with a low efficiency; the Ca2+: N accumulation rati...

Distribution of Acid-soluble Phosphorus in the Blood Cells of Various Vertebrates

This paper presents data on the distribution of acid-soluble phosphorus compounds in the blood cells of a few apparently normal individuals of each of forty-six species: twenty-two mammalian, twelve avian, six reptilian, four amphibian, and two fish. Since the studies were limited by availability of material, each order is represented by only a few species, and in many instances only one blood ...

Effects of the essential oil constituent thymol and other neuroactive chemicals on flight motor activity and wing beat frequency in the blowfly Phaenicia sericata.

BACKGROUND The effects were evaluated of the plant terpenoid thymol and eight other neuroactive compounds on flight muscle impulses (FMIs) and wing beat frequency (WBF) of tethered blowflies (Phaenicia sericata Meig.). RESULTS The electrical activity of the dorsolongitudinal flight muscles was closely linked to the WBF of control insects. Topically applied thymol inhibited WBF within 15-30 mi...
