Effect of Angiotensin II on Cyclic Guanosine Monophosphate and Cyclic Adenosine Monophosphate in Human Plasma

The Journal of Clinical Endocrinology & Metabolism, 1976
Infusion of alpha-adrenergic catecholamines increases plasma cyclic guanosine monophosphate (pcGMP), raising the possibility that the pressor effect of these agents may be mediated by cyclic GMP. We infused pressor doses of angiotensin II in 10 studies in 8 normal subject and measured pcGMP and plasma cyclic adenosine monophosphate (pcAMP) by ...

Hydrolysis of cyclic guanosine monophosphate and cyclic adenosine monophosphate by the penis and aorta of the diabetic rat

British Journal of Urology, 1996
Objective  To investigate the hydrolysis of adenosine 3′5′‐cyclic monophosphate (cAMP) and guanosine 3′5′‐cyclic monophosphate (cGMP) by specific phosphodiesterases (PDEs) in the penis and aorta of diabetic rats. Materials and methods

Cyclic Adenosine Monophosphate in Cerebral Cortex

Archives of Neurology, 1975
Stab-wound injury produced a seven-fold elevation in cyclic adenosine monophosphate (AMP) in mouse brain within one minute. The increase in cyclic AMP in the brain was blocked by prior treatment of the animal by theophylline, chlorpromazine, trifluoperazine hydrochloride, and diphenhydramine hydrochloride. Neither dichloroisoproterenol, pronetalol, nor

Determination of Cyclic Adenosine 3′,5′-Monophosphate in Urine

Scandinavian Journal of Clinical and Laboratory Investigation, 1976
A modification of Aurbach & Houston's enzymic method for measuring cAMP is presented. The procedure is relatively simple and in several respects new. Urinary cAMP is separated from other nucleotides and phosphate by ZnSO4-Ba(OH)2 precipitation and column chromatography. The eluate is concentrated by evaporation. Recovery at this stage is 60-82%.

Cyclic Adenosine Monophosphate (CAMP) and Cyclic Guanosine Monophosphate (CGMP)

Abstract Human physiology is highly dependent on a well-coordinated system of communication between cells. A multitude of external signals, including hormones, neurotransmitters, and other molecules, interact with cells via specific cell-surface receptors.

Dibutyryl cyclic adenosine monophosphate inhibits pulmonary vasoconstriction

Lung, 1988
The effects of the cell-permeable dibutyryl derivative of cyclic AMP on the vascular reactivity of isolated perfused rat lungs were examined. In lungs perfused with homologous blood, pulmonary arterial infusion of db-cAMP (30 micrograms/min) inhibited hypoxia-induced vasoconstriction (IC50 = 6.3 X 10(-5) M) and vasoconstriction due to bolus injection ...

Cyclic 3′,5′-adenosine monophosphate and bronchial tone

European Journal of Pharmacology, 1977
The present studies demonstrate that adenylate cyclase and cyclic 3',5'-adenosine monophosphate (cAMP)-phosphodiesterase activities in dog bronchus are comparable to those found in other smooth muscle preparations. Catecholamines, in the order isoproterenol greater than epinephrine greater than norepinephrine, increase the rate of cAMP formation.

Cyclic Adenosine Monophosphate Production by Embryonic Chick Cells

Science, 1978
Cells dissociated from 1-day-old chick embryos produce a pulse of cyclic adenosine monophosphate (cyclic AMP) when stimulated with cyclic AMP. There is a stimulus threshold concentration of about 10 -8 molar cyclic AMP and an upper limit, above which the response is suppressed, of about 6 × 10 -6
