Nonsteroidal anti-inflammatory drugs produce their analgesic and adverse effects through interaction with cyclooxygenase in a variety of tissues. The authors evaluated the therapeutic potential of administering a sustained-release formulation of flur

Dantrolene effectively treats malignant hyperthermia (MH) but the current form, Dantrium®, must be dissolved to a 0.33 mg/mL, pH 9.5 solution. This study describes lecithin-coated microcrystal formulations of sodium dantrolene (MC-NaD) and neutral d

This study was designed to determine if microencapsulated tetracaine would provide a longer duration of local anesthesia than nonmicroencapsulated (neat) tetracaine. Local anesthesia was determined by monitoring the response of the rat to tail clampi

Determinations of pHcyt in suspensions of human platelets using BCECF [bis(carboxyethyl)-5(6)-carboxyfluorescein] can be seriously biased by leakage of the fluorescent indicator. Two methods ("pH jump" and "Mn(2+)") are presented for determining the

Sodium nitroprusside (SNP) and other agents that elevate cGMP levels are known to inhibit the aggregation of human platelets. Published data suggest that cGMP attenuation of agonist-induced Ca2+ transients is involved in this effect. The present stud

The effect of cAMP on active Ca2+ extrusion across the plasma membrane of intact human platelets was studied using quin2, a fluorimetric indicator of free Ca2+ in the cytoplasmic compartment ([Ca2+]cyt). Elevations of cAMP were achieved by incubation

The pH dependence of the Ca2(+)-transporting ATPase of bovine cardiac sarcolemma was determined in a membrane vesicle preparation. The maximal velocity (Vmax) at saturating external Ca2+ showed a sigmoidal pH dependence with maximal values in the 6.0

This communication reports the kinetics of the Na+/Ca2+ exchanger and of the plasma membrane (PM) Ca2+ pump of the intact human platelet. The kinetic properties of these two systems were deduced by studying the rate of Ca2+ extrusion and its Na+ depe

The effects of protein kinase C (PKC) on Ca2+ transport were investigated in human intact platelets. The indicator quin2 was used to measure the free cytoplasmic Ca2+ concentration ([Ca2+]cyt) and to search for possible PKC effects on the Ca(2+)-ATPa
