Factors influencing corneal predescemetic endothelial keratoplasty (PDEK) graft creation: It's all in a bubble.

Aim: To assess the effect of pneumatic (air) and fluidic (transport medium) injection to the type of bubble (I, II or mixed III) and the resultant dissection of corneal endothelial grafts PDEK or DMEK.

Materials And Methods: All grafts were obtained from Dr Agrawal Hospital's Eye Bank. Air injection was the initial preferred mode of graft harvest.

Comparison of felodipine and nitroglycerin actions on vasomotion physiology.

Felodipine is a Calcium blocker and nitroglycerin, a nitrate vasodilating agent, were compared. Two parameters were studied in vitro on bovine aortic media. Calcium uptake and vascular tone.

Iohexol does not influence the levels of blood serum cation electrolytes during intravenous pyelography.

Purpose: The influence of the nonionic contrast agent iohexol on blood pH and the cation electrolytes Ca, Na, K and Mg was studied in vivo in humans during the intravenous pyelography.

Material And Methods: A population of 28 patients without renal function impairment or electrolyte imbalance was divided into two equal groups. The first group received an intravenous injection of 0.

Effects in vivo of iohexol and diatrizoate on human plasma acetyl- and butyryl-cholinesterase activity.

Purpose: The aim of this study was to evaluate the effects of two iodinate contrast agents (CA), iohexol and diatrizoate, on human plasma acetyl-(AC) and butyrylcholinesterase(BC) activity.

Material And Methods: Forty-eight patients (24 males and 24 females) scheduled for intravenous pyelography were randomly divided into four groups of 6 males and 6 females each, receiving as CA, respectively: iohexol (Omnipaque, Schering) 0.6 ml/kg body weight (G1); iohexol 1.

The effect of some iodinated contrast media on human plasma butyrylcholinesterase activity.

The effect of three iodinated contrast media (CM) on human plasma butyrylcholinesterase (BuChE) activity was studied during the intravenous pyelography (i.v.P).
