The effects of hydroxyl radical exposure of intact cardiomyocytes on sarcoplasmic reticulum (SR)
function were investigated. For this purpose, isolated rat heart myocytes were exposed …

Protein phosphorylation was investigated in [ 32 P]-labeled cardiomyocytes isolated from
adult rat heart ventricles. The β-adrenergic stimulation (by isoproterenol, ISO) increased the …

Adenylate cyclase was studied in plasma membranes prepared from rabbit skeletal muscle.
Such preparations represented an increase in specific activity of 10- to 20-fold over the …

The ability of heavy microsomes and mitochondria, isolated from the control and failing hearts
of genetically dystrophic hamsters (BIO 14.6 strain), to accumulate calcium was examined. …

The release of tritiated adenosine and its derivatives from the surface of the pericruciate
sensorimotor cortex of cats has been measured. Most of the radioactive material was released …

… In agreement with the previous observations from this laboratory (Wei and Sulakhe, 1979a,
b; 1980), the present study shows that in the case of rat heart atrial muscarinic receptor sites, (…

Regional and subcellular distribution of muscarinic cholinergic receptors were investigated
in the myocardium of commonly used laboratory animals. The density of receptor sites (…

A method for the isolation of skeletal muscle membrane is described. These membrane
fragments were found to contain a highly active Na + K + stimulated Mg ++ dependent ATPase …

Plasma membranes isolated from rabbit muscle possessed the ability to bind and accumulate
calcium ions; these processes required ATP and Mg 2+ . Binding of Ca 2+ was rapid, …

MATERIALS AND METHODS Mongrel dogs(10-15kg) were anesthesized with 30mg/kg
sodium pentobarbitol(intrave nously). The hearts were rapidly removed and placed in ice cold …
