The effect of erythropoietin on healing of obstructive vs nonobstructive left colonic anastomosis: an experimental study

<p>Abstract</p> <p>Background</p> <p>Anastomotic leakage is an important problem following primary resection in the left colon and is even more prominent when obstruction is present. We aimed to evaluate the possible effects of erythropoietin on the healing of anastomosis under both obstructive and non-obstructive states.</p> <p>Methods</p> <p>Forty male Wistar albino rats were divided into four groups. In group I, two cm left colonic resection and primary anastomosis were done. In group II, left colon were completely ligated and 24 hours later animals were re-operated for segmental resection. The same procedures were performed for rats in group III and IV in respect to group I and II and, 500 IU/kg a day erythropoietin were given in the latter two groups for seven days. For the quantative description of anastomotic healing mechanical, biochemical and histopathological parameters were employed on the seventh day and the animals were sacrificied.</p> <p>Results</p> <p>Although erythropoietin had positive effects on bursting pressure in group IV when compared to group II, it has no effect in group III. Despite the increased tissue hydroxyproline levels in group IV, erythropoietin failed to show any effects in group III.</p> <p>Erythropoietin had positive effects on neovascularization, fibroblast proliferiation and storage of collagen in group IV.</p> <p>Conclusion</p> <p>We failed to find any direct and evident effects of erythropoietin on healing of left colonic anastomosis. On the other hand, erythropoietin might prevent negative effects of obstruction on healing.</p

Antimicrobial Activity Of Three Scutellaria L. Species From Turkey

Plant-sourced antimicrobials are known for their therapeutic potency against multi-drug-resistant pathogens. The members of Scutellaria L. have been used to cure several diseases in East Asia, Europe, and North America. The genus Scutellaria belonging to Lamiaceae family is composed of around 360 species worldwide and 18 species in Turkey. In this study, 36 extracts prepared with different solvents from aerial parts and roots of S. salviifolia Benth., S. diffusa Benth. and S. pontica C. Koch were investigated for their antimicrobial activity against four bacteria (Escherichia soli ATCC 25922, Enterococcus faecalis ATCC 29212, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 29213) and three yeasts (Candida albicans ATCC 90028, C. krusei ATCC 6258, C. parapsilosis ATCC 90018) by using the broth microdilution method. Gentamicin, vancomycin and fluconazole were used as positive control. According to our results, all of the tested extracts showed stronger antimicrobial activity against yeasts than bacteria. The chloroform extract of S. salviifolia root showed the highest antifungal effect against C. krusei with 32 mu g/ml MIC value compared with all the tested extracts and the positive control fluconazole (64 mu g/ ml MIC value).WoSScopu

The effects of local and sustained release of fibroblast growth factor on wound heating in esophageal anastomoses

Background/ Purpose: Postsurgical complications, such as anastomotic leaks in patients with esophageal atresia, have remained unchanged during the last 3 decades. Growth factors enhance healing in several wound-healing models. Therefore, an experimental study was used to evaluate the effects of local and sustained release of basic fibroblast growth factor (FGF) on wound healing in esophageal anastomoses
