The present study investigated the potent therapeutic effects of Ruscogenin, main steroid sapogenin traditional Chinese plant called 'Ophiopogon japonicas', on chronic ulcer model established with acetic acid in rats.24 rats were attenuated to sham (2 ml/kg/day isotonic solution), control (untreated ulcer) and treatment (3 ruscogenin) groups. After for 2 weeks, gastric tissues collected prepared light microscopic (H&E), immunohistochemical (Collagen I, III IV) biochemical analysis [Epidermal...

Despite many advances in surgery and technology, colonic anastomosis remains a challenge after resection. The purpose of this study is to compare the safety using diclofenac sodium paracetamol for analgesia on rats. Wistar–Hannover rats were randomly allocated four groups: Group 1, sham-operated group; 2, control 3, 4, group. After laparotomy, left colon was transected single-layer made with 5/0 vicryl Groups 4. Only laparotomy performed 1. anastomosis, we administered saline 4 7 days. Then,...

Obstructive jaundice (OJ) can be defined as cessation of bile flow into the small intestine due to benign or malignant changes. Nesfatin-1, recently discovered anorexigenic peptide derived from nucleobindin-2 in hypothalamic nuclei, was shown have anti-inflammatory and antiapoptotic effects. This study is aimed investigate therapeutic effects nesfatin-1 on OJ rats. Twenty-four adult male Wistar-Hannover rats were randomly assigned three groups: sham (n = 8), control nesfatin 8).
