Ultrastructural localization of cholinesterase activity in the developing rat retina.
Retinae of rats from the 16th day of gestation to 10 weeks postnatal age were treated for the ultrastructural localization of cholinesterases according to the method of Lewis and Shute. The use of selective inhibitors served to differentiate between acetylcholinesterase and nonspecific cholinesterase activities. Nonspecific cholinesterase activity was marked in the rough endoplasmic reticulum o...
متن کاملTotal cholinesterase activity in discrete brain regions and retina of normal horses.
The organophosphorus and carbamate insecticides inhibit cholinesterase, causing an increase of acetylcholine at neuromuscular junctions. Toxicosis due to anticholinesterase compounds can be diagnosed by finding depressed cholinesterase activity in the blood, brain, and/or retina. Cholinesterase activity < 50% of normal has been associated with significant exposure to an anticholinesterase agent...

15 صفحه اولThe Distribution of Cholinesterase
Acetylcholinesterase and butyrylcholinesterase activities were demonstrated in transverse sections of the rabbit ear artery using a “direct coloring” thiocholine technique. BW 284C5l, iso-OMPA and DFP were used as inhibitors, and acetyl and butyrylthiocholine iodides as substrates. Both enzymes caused stain deposits at the medial-adventitial border of the artery, in a region where sympathetic n...
متن کاملDetection of cholinesterase inhibition. The significance of cholinesterase measurements.
Human cholinesterase exists in two forms--acetylcholinesterase located in tissue microsomes and red blood cells and serum cholinesterase found in serum or plasma. The two enzymes display marked differences in structure, substrate specificity, biological function, and origin. Contemporary methods employ acylthiocholine as substrate for serum cholinesterase and a second coupled reaction of thioch...
