E VALUATION OF ADENYLATE CYCLASE ACTIVITY IN MITRAL VALVE PROLAPSE
The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...
متن کاملUltrastructural Cytochemistry
Selective extraction of specific cell components by enzyme or acid hydrolysis is possible from ultrathin sections for electron microscopy and parallel 2 micro sections for light microscopy of tissues fixed in formalin and embedded in a water-soluble polyepoxide, product X133/2097. Normal rat tissues fixed 15 minutes in formalin at 3 degrees C are more rapidly digested by proteinases than those ...

متن کاملadenylate cyclase activity
Adipocyte membranes from control rats exhibited a functional Gi (inhibitory guanine-nucleotide-binding protein) activity which could be assessed either by the inhibitory action of low concentrations of guanosine 5-[/Jy-imido]triphosphate (p[NH]ppG) upon forskolin-stimulated adenylate cyclase activity or by the inhibitory action of high concentrations of GTP upon isoprenaline-stimulated adenylat...
متن کاملForskolin-activated Adenylate Cyclase
Forskolin activated adenylate cyclase of purified rat adipocyte membranes in the absence of exogenous guanine nucleotides. Guanyl-5”yl imidodiphosphate (Gpp(NH)p) inhibited the forskolin-activated cyclase immediately upon addition of the nucleotide at concentrations too low to activate adenylate cyclase (lo-’ to M). Inhibition seen with a very high concentration of Gpp(NH)p M) lasted for 3-4 m...
