Conventionally adrenergic-anticholinergic combination eye drops (e.g., phenylephrine-tropicamide) are used for pre-operative pupillary dilatation in cataract surgery. This achieves synergy dilatation, but anticholinergic-induced cycloplegia makes already tense lens-capsule of intumescent more taut, and completion capsulorrhexis becomes difficult, often resulting Argentanian flag sign, periphera...

ignoring two main characteristics of the concentration-response data, correlation between observations and presence of outliers, may lead to misleading results. therefore the special method should be considered. in this paper in to examine the effect of phenylephrine in rat corpus cavernosum, outlier robust nonlinear mixed estimation is used. in this study, eight different doses of phenylephrin...

Aim . To study the intraprocedural changes in baroreflex activity after catheter pulmonary vein isolation paroxysmal atrial fibrillation patients. Methods. From October 2021 to June 2022, sinus rhythm was registered at start of procedure 21 patients with admitted for isolation. Patients before and were tested phenylephrine. Pre- postoperative rate analyzed. Results. After isolation, decreased f...

angiotensin ii is a major endocrine hormone that affects directly both vascular smooth muscle and endothelial cells. since vascular reactivity to angiotensin ii changes in more physiological and pathophysiological conditions, the present study was performed to investigate the effect of intraperitoneal administration of angiotensin-converting enzyme inhibitor and captopril (30 and 50 mg kg-1, on...

A dark-field ophthalmic contact probe for analysis of aqueous humor (AH) was designed by ray tracing and constructed in quartz glass experimental use as a prototype confocal Raman spectroscopic setup. The misalignment tolerance this theoretically evaluated, whereas the optical performance experimentally evaluated concentration curve ocular drug phenylephrine HCl an artificial eye model. results...

Phenylephrine is effective for the management of spinal anesthesia-induced hypotension in parturients undergoing cesarean delivery under spinal anesthesia. While ephedrine was previously considered the vasopressor of choice in obstetric patients, phenylephrine is increasingly being used. This is largely due to studies suggesting improved fetal acid-base status with the use of phenylephrine as w...

BACKGROUND The aim of this study was to investigate the role of mitochondrial permeability transition pore (mPTP) in cardioprotection afforded by phenylephrine pretreatment in early and late phases. METHODS Rat hearts were isolated and perfused with Krebs buffer in Langendorff preparation and subjected to 30 min regional ischemia followed by 60 min of reperfusion. Phenylephrine as a selective...
