BACKGROUND AND OBJECTIVES The aims of this study were to establish a reliable model of chronic mitral regurgitation (MR) in rats and verify the pathophysiological features of this model by evaluating cardiac function using serial echocardiography and a pressure-volume analysis. MATERIALS AND METHODS MR was created in 37 Sprague-Dawley rats by making a hole with a 23 gauge needle on the mitral...
BACKGROUND/AIMS To establish an animal model of laryngopharyngeal reflux (LPR) and study the effect of LPR on the laryngopharyngeal mucosal ultrastructure. METHODS Ten Bama minipigs were randomly divided into control group and stent group. Every pig underwent endoscope, and baseline pH was monitored for 4 hours at laryngopharynx and distal esophagus, then specimens from laryngopharyngeal muco...
The protective effect of Lycium ruthenicum Murr. against radiation injury was examined in mice. Kunming mice were randomly divided into a control group, model group, positive drug group and L. ruthenicum high dose (8 g/kg), L. ruthenicum middle dose (4 g/kg), L. ruthenicum low dose (2 g/kg) treatment groups, for which doses were administered the third day, seventh day and 14th day after irradia...
