اثرات تئوفیلین در بیماران سندرم X
A role of adenosine in pathogenesis of syndrome X has recently been postulated. Previous studies suggest that aminophylline (An adenosine receptor blocker) improves exercise tolerance in this disorder. Present study was performed to examine the efficacy of Theophylline in syndrome X and to determine the incidence of cardiovascular risk factors and clinical, ECG and angiographic findings in thes...
متن کاملA Kinetic Comparison on the Inhibition of Adenosine Deaminase by Purine Drugs
The effects of allopurinol, acyclovir and theophylline on the activity of adenosine deaminase (ADA) were studied in 50 mM sodium phosphate buffer pH 7.5 at 27°C, using a UV– Vis spectrophotometer. Adenosine deaminase is inhibited by these ligands, via different types of inhibition. Allopurinol, as a transition state analog of xanthine oxidase, and acyclovir competitively inhibit the catalytic a...

متن کاملSyncope and paroxysmal atrioventricular block
Current literature reveals three types of paroxysmal atrioventricular block (AVB) that can cause syncope: Intrinsic paroxysmal atrioventricular block is due to an intrinsic disease of the AV conduction system; this type of "cardiac syncope" is also called Stokes-Adams attack; Extrinsic vagal paroxysmal atrioventricular block is linked to the effect of the parasympathetic nervous system on cardi...
متن کاملSyncope and Idiopathic (Paroxysmal) AV Block.
Syncope due to idiopathic AV block is characterized by: 1) ECG documentation (usually by means of prolonged ECG monitoring) of paroxysmal complete AV block with one or multiple consecutive pauses, without P-P cycle lengthening or PR interval prolongation, not triggered by atrial or ventricular premature beats nor by rate variations; 2) long history of recurrent syncope without prodromes; 3) abs...
