up to date, there are four pharmacologically characterized subtypes of muscarinic receptors (m1, m2, m3 and m4). in our study we have investigated muscarinic receptor subtypes in smooth muscle layers of human stomach. isolated preparations of longitudinal and circular muscle layers from human stomach were used. acetylcholine, bethanechol, carbachol, pilocarpine and ahr -602 produced concentrati...

nucleolar organizer regions (nor) are defined as nucleolar components containing a set of argyrophilic proteins which are selectively stained by colloidal silver nitrate staining. although studies have shown that the number of nor dots or particles is directly related to the rapidity of cell proliferation in cancer cells, prognostic or diagnostic value of nor remains controversial. the aim of t...
