Platelet membrane alterations induced by the local anesthetic dibucaine.
Tertiary amine local anesthetics modify a variety of platelet membrane-related functions. The present study explored dibucaine (DB)-induced inhibition of platelet cohesion by examining structural and functional alterations of the human platelet membrane glycoprotein IIb-IIIa complex (GPIIb-IIIa) and platelet Ca2+ homeostasis. Complete inhibition of ADP-induced aggregation was achieved five minu...
متن کاملLocal Anesthetic-Induced Neurotoxicity
This review summarizes current knowledge concerning incidence, risk factors, and mechanisms of perioperative nerve injury, with focus on local anesthetic-induced neurotoxicity. Perioperative nerve injury is a complex phenomenon and can be caused by a number of clinical factors. Anesthetic risk factors for perioperative nerve injury include regional block technique, patient risk factors, and loc...
متن کاملIon transport processes in corn mitochondria : I. Effect of the local anesthetic dibucaine.
The local anesthetic dibucaine inhibited respiration-dependent contraction mediated by the K(+)/H(+) antiport system of isolated corn mitochondria. Respiration declined concurrently. Nigericin, an exogenous K(+)/H(+) exchanger, restored ion efflux in dibucaine-blocked corn mitochondria. It was concluded that dibucaine inhibited ion efflux via blockage of the K(+)/H(+) antiport. Further experime...
متن کاملMembrane interactivity of charged local anesthetic derivative and stereoselectivity in membrane interaction of local anesthetic enantiomers
With respect to the membrane lipid theory as a molecular mechanism for local anesthetics, two critical subjects, the negligible effects of charged drugs when applied extracellularly and the stereoselective effects of enantiomers, were verified by paying particular attention to membrane components, phospholipids with the anionic property, and cholesterol with several chiral carbons. The membrane...
متن کاملEffect of the local anesthetic dibucaine on the surface membrane in sterol-manipulated Tetrahymena pyriformis studied by freeze-fracture electron microscopy.
The effect of the local anesthetic dibucaine on the membrane ultrastructure of sterol-manipulated Tetrahymena pyriformis (NT-1 strain) was studied by freeze-fracture electron microscopy. Dibucaine-treated, ergosterol-replaced Tetrahymena cells had marked alterations in their plasma membranes. IMP-free small depressions (exoplasmic fracture face) and protrusions (protoplasmic fracture face) were...
