Potentiating effects of caffeine on the teratogenicity of acetazolamide in two strains of mice
… the effect of caffeine on the teratogenicity of acetazolamide in susceptible and resistant strains of inbred mice. The highly susceptible C57BL/6J and more resistant SWV strain were used. Pregnant C57BL/6J and SWV mice were treated with caffeine, low or high dose acetazolamide, or a combination …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
… reserve (CVR) by using CT perfusion (CTP) with acetazolamide (ACZ) challenge could identify patients at risk for hyperperfusion after CS. For 12 patients with symptomatic unilateral or bilateral carotid stenosis (> 70%), hemodynamic parameters including cerebral blood volume (CBV), cerebral …

Quantitative Cerebrovascular Reserve Measured by Acetazolamide-Challenged Dynamic CT Perfusion in Ischemic Adult Moyamoya Disease : Initial Experience with Angiographic Correlation
… quantitative cerebrovascular reserve by using acetazolamide (ACZ)-challenged CT perfusion for evaluating hemodynamic impairment in ischemic adult Moyamoya disease and compared it with angiographic findings. Sixteen adult patients with ischemic Moyamoya disease and 12 age-matched normal control …

Acidification in the Rat Proximal Jejunum
… Acidification was unaffected by 10mM mucosal acetazolamide and 10mM ouabain which excluded bicarbonate movement and made active sodium transfer unlikely, as causing acidification. Acidification was diminished by anoxia, by phlorrhizin and by DNP at concentrations that prevent oxidative …

Cerebral blood flow in the non-human primate : an in vivo model and drug interventions
… The drugs that were included in the study were acetazolamide, a carbonic acid anhydrase inhibitor (often used in nuclear medicine to determine cerebral reserve); sumaptriptan, a 5-HT (serotonin) agonist used for treatment of migraine; sodium valproate (an anti-epileptic drug); nimodipine, a …

Regulation of duodenal mucosal bicarbonate secretion
… secretion can be inhibited by somatostatin and acetazolamide. Somatostatin selectively suppresses carbachol-stimulated and VIP-stimulated duodenal bicarbonate secretion, but not PGE2-stimulated bicarbonate secretion. Receptors for somatostatin coupled to adenylate cyclase could not be detected …

Idiopathic Intracranial Hypertension
… trial in IIH is then reported. Treatment with acetazolamide was examined prospectively in 50 patients, providing seminal information to guide the design of future large-scale trials and data on the natural history of the condition. The observation that management of IIH is guided by a variety …

Zero length crosslinking of bovine carbonic anhydrase II and chondroitin-4-sulfate
… The effects of a noncompetitive inhibitor, acetazolamide, were similar between the crosslinked complex (KI = 3.87 x 10-8 M) and the unmodified enzyme (KI = 4.62 x 10-8 M). However, the modified enzyme was more resistant to denaturation by guanidine hydrochloride, SDS and heat. Covalent …

Distal tubule bicarbonate reabsorption.
… (4) inhibition of carbonic anhydrase by acetazolamide. At 8 nl/min, collection of fluid from tubules perfused with all 4 solutions revealed significant bicarbonate reabsorption. Net distal tubule bicarbonate reabsorption was significantly increased in acidotic animals. Perfusion of …

Acute Effects of Acetazoleamide (Diamox) Administration on Pulmonary Carbon Dioxide Exchange in Humans
<p>Previous studies dealing with the effects of oral acetazoleamide (Diamox<sup>R</sup>) administration in humans have yielded equivocal results. Effects of intravenous administration of this agent, a potent carbonic anhydrase inhibitor, have not been studied until recently. It is postulated that …
