OBJECTIVE The aim of this study is to compare micro-sutures commonly used in our midst. METHODS In this double-blind study, 30 Wistar rats were operated randomly divided into three groups matched according to the suture used (Nylon 10-0, 75micron, brands Microsuture((r)), Polysuture((r)) and Ethicon((r))). We analyzed the number of surgical nodes required, bleeding, surgical time and histolog...

(NTS) in Wistar rats (WR) and spontaneously hypertensive rats (SHR), our previous results suggested that sustained hypertension might aggravate the nephrotoxic processes or protract the course of glomerulonephritis. The present study was attemped to observe the more prolonged glomerular changes of nephrotoxic nephritis (NTN) until 15 weeks after the injection of NTS in SHR, compared with contro...
