| 2',3'-cyclic nucleotide 2'-phosphodiesterase | <enzyme> Catalyses the hydrolysis of the 2'-phosphodiesterase bond to yield nucleoside 3'phosphate Registry number: EC 3.1.4.16 Synonym: 2',3'-cyclic nucleotide 2'-phosphohydrolase (26 Jun 1999) |
| 2',3'-cyclic nucleotide 3'-phosphodiesterase | <enzyme> Catalyses the hydrolysis of the 3'-phosphoesterase bond to yield nucleoside 2'-phosphate Registry number: EC 3.1.4.37 Synonym: 2',3'-cyclic nucleotide 3'-phosphohydrolase, 2',3'-cn phosphodiesterase, 2',3'-cnpase (26 Jun 1999) |
| 2',3'-cyclic-nucleotide phosphodiesterases | <enzyme> Nucleoside-2',3'-cyclic phosphate nucleotidohydrolase. Enzymes that catalyze the hydrolysis of the 2'- or 3'- phosphate bonds of 2',3'-cyclic nucleotides. Also hydrolyzes nucleoside monophosphates. Registry number: EC 3.1.4.- (12 Dec 1998) |
| 3',5'-cyclic-nucleotide phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of cyclic AMP to form adenosine 5'-phosphate. The enzyme is widely distributed in animal tissue and controls the level of intracellular cyclic AMP. Also acts on 3',5'-cyclic imp and 3',5'-cyclic GMP. Chemical name: 3',5'-Cyclic-nucleotide 5'-nucleotidohydrolase Registry number: EC 3.1.4.17 (12 Dec 1998) |
| alveolocapillary block | The presence of material that impairs the diffusion of gases between the air in the alveolar spaces and the blood in alveolar capillaries; block can be caused by oedema, cellular infiltration, fibrosis, or tumour, and results in undersaturation of peripheral arterial blood with oxygen. (05 Mar 2000) |
| anterograde block | Conduction block of an impulse traveling anywhere in its ordinary direction, for example, from the sinoatrial node toward the ventricular myocardium. (05 Mar 2000) |
| arborization block | Intraventricular block supposedly due to widespread blockage in the Purkinje ramifications and manifested in the electrocardiogram by a pattern similar to bundle-branch block but with complexes of low amplitude. (05 Mar 2000) |
| atrioventricular block | <cardiology> A conduction disturbance that results in the inappropriate delay (or complete inability) of a electrical impulse, generated in the atria, to reach the ventricles (via the atrioventricular node). Clinical types are divided into first (nonserious), second and third degree (most serious). Some drugs may precipitate atrioventricular block (for example clonidine, methyldopa, verapamil). A permanent pacemaker may be required for a third degree (complete) heart block. (02 Jan 1998) |
| autonomic nerve block | Interruption of sympathetic pathways, by local injection of an anaesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block. (12 Dec 1998) |
| A-V block | <cardiology> A conduction disturbance that results in the inappropriate delay (or complete inability) of a electrical impulse, generated in the atria, to reach the ventricles (via the atrioventricular node). Clinical types are divided into first (nonserious), second and third degree (most serious). Some drugs may precipitate atrioventricular block (for example clonidine, methyldopa, verapamil). A permanent pacemaker may be required for a third degree (complete) heart block. (02 Jan 1998) |
