Adhesion Formation and Intraperitoneal Catheters

OBJECTIVE: Aim of the present study was to determine effect of silicone and polyvinyl chloride in a rat model. STUDY DESIGN: A randomised blind study was performed using a rat model of laparotomy. Setting: Surgical Research laboratory in a university medical school. İntervention(s): Fifty four rats were divided into three groups:Group 1 (n:18),simple laparotomy; and group 2 (n:18) polyvinyl chloride were placed intraperitoneally;Group 3 (n:18),silicone was placed intraperitoneally. Main outcome measure(s): Three weeks after laparotomy,repeat laparotomy was performed and the adhesions were scored. RESULT General adhesion scores in groups 2 and 3 were higher than in group 1 (p<0.05). İn group 1, none of the rats presented adhesion.The results for groups 2 and 3 were similar. CONCLUSIONS: The overall adhesions score did not differed significantly between groups 2,3.Silicone and polyvinyl chloride causes adhesion development in rat model

Synthesis of taurine-Cu-3(PO4)(2) hybrid nanoflower and their peroxidase-mimic and antimicrobial properties

Herein, we report the synthesis of taurine incorporated (sulfur containing organic molecule derived from methionine and cysteine) hybrid nanoflowers (thNFs) with an intrinsic peroxidase-mimic and antimicrobial activities in the presence of H2O2. Formation of thNFs using non-enzyme molecules was for the first time and systematically studied as a function of the taurine concentration, types of metal ions (Cu2+, Fe2+ and Fe3+) and pH values of reaction solution. The peroxidase like activities of thNFs rely on Fenton-like reaction against guaiacol used as a model substrate. The efficiency of Fenton reaction can be attributed to porous structure and presence of ions of transition elements in the thNFs. The thNFs were further characterized using FTIR, XRD, SEM and EDX. The thNFs also showed remarkable antimicrobial properties against S. aureus, E. coli, B. cereus and C. albicans. We claim that nonprotein-based NFs can be considered as new generation nano-biocatalysts as an alternative to enzymes and can be used in various medicinal, biochemical, immunological, biotechnological, and industrial applications.Erciyes University TYL-2018-8578 TCD-2019-848
