In this study, efficacy of two hernia mesh implants viz. conventional Prolene and a novel Prolene-Vicryl composite mesh was assessed for experimental ventral hernia repair in dogs. Twelve healthy mongrel dogs were selected and randomly divided into three groups, A, Band C (n=4). In all groups, an experimental laparotomy was performed; thereafter, the posterior rectus sheath and peritoneum were ...

The use of the dog as an experimental animal in neuro-and psyehopharmacologieal studies is increasing because many drugs affect the dog in a manner similar to that of man. At least two stereo-taxic atlases of the mongrel and/or beagle dog already have been published (Leontovich and Meting 1956; Lim et al. 1959) and several others are in the planning stage. Hume and Ganong (1956) have described ...

To determine whether chronic high-fructose feeding causes insulin resistance and hypertension in normal dogs, we fed 10 male dogs a normosodic diet containing 60% of the calories as fructose for 20 to 28 days; a control group of 8 dogs was fed a similar diet containing dextrose instead of fructose. In the fructose-fed group, (1) fasting triglyceridemia increased from 35.3 +/- 0.63 to 91.9 +/- 1...

The response of native collateral circulation to chronic stenosis of the left circumflex coronary artery (LCx) was studied in 17 mongrel dogs. Stenosis restricted reactive hyperemia of the LCx without affecting resting flow. Regional myocardial blood flow was measured by the tracer microsphere technique. Coronary collateral blood flow to the LCx was determined during maximal reactive hyperemia ...

The purpose of the study. There are investigation possibility using laser Doppler flowmetry method to assess blood microcirculation and analyze mechanisms its regulation in conditionally intact ischemic myocardium small laboratory animals (rats) identify "coronary theft" syndrome. Materials methods. experiments were carried out on white mongrel anesthetized (urethane 1300 mg/kg /b) male rats we...

The present study was designed to evaluate the ability of magnesium sulfate (30 mg/kg, iv, 24 hr and 2 hr prior) to limit myocardial infarct size following permanent left coronary artery occlusion in adult mongrel dogs. Non-perfused myocardium which is the area at risk was visualised by injecting methylene blue intraatrially, 24 hr after coronary artery occlusion. The infarcted myocardium was v...

Mongrel dogs were treated intravenously with either 1000 units of beef-lung heparin per kilogram of body weight or with isotonic saline, before intravenous administration of E. coli endotoxin. We found significant differences in circulating norepinephrine concentrations between a heparin-pretreatment group (1.89 +/- 0.39 microgram/liter) and the control group (9.83 +/- 4.64 microgram/liter), bu...

The case of a 14-year-old mongrel dog with a thyroid tumor treated by thyreoidectomy is described. The resected tumor was subjected to a detailed morphological and immunohistochemical analysis utilizing antibodies directed against thyroglobulin, calcitonin, chromogranin A, cytokeratin 19, thyroid transcription factor-1, CD31, Ki-67 and minichromosome maintenance protein 3. Expression level of t...
