Scanning electron microscopy of vas deferens epithelium after temporary alteration caused by radiopaque medium. 1998

Department of Morphology, Federal University of Sao Paulo, Escola Paulista de Medicina, Brazil.

Nine male rats (Rattus norvegicus albinus) weighing approximately 300 g were divided into 3 groups: a control group (CG), an experimental group of 7 days (EG-7), and an experimental group of 35 days (EG-35). All rats except those in the control group underwent a left vasography. The EG-7 and EG-35 rats were killed on the 7th and 35th days, respectively, after vasography; CG rats were killed on a randomly chosen day. The histological sections and scanning electromicrographs showed that the temporary alterations caused by radiopaque medium on vas deferens mucosa seen on the 7th day after vasography were completely repaired on the 35th day of recovery and either apical secretion or stereocilia of principal cells were reestablished.

D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
