The technique of distal pancreatectomy has been well described, both with en bloc resection of the spleen and with splenic preservation. Splenic preservation during pancreatic tail resection is desirable when oncologically appropriate, yet it is technically challenging, particularly with laparoscopic approaches. Skeletonization of the splenic artery and(More)
Tilmicosin(TM), a macrolide antibiotic and active ingredient in formulated Micotil 300 (Eli Lilly and Co., Indianapolis, IN, USA), is the active ingredient in a formulated animal product used for the treatment of respiratory tract infections in cattle. Owing to the concern of governmental regulatory agencies over the possibility of an accidental injection(More)
The purpose of this investigation was to assess protection by zinc against acetaminophen induced hepatotoxicity and to evaluate possible mechanisms of protection. Mice were treated with zinc (3 mg/kg, ip) or saline (ip) 48 and 24 hr before and sacrificed 12 hr after acetaminophen administration (375, 500, or 750 mg/kg, po). Liver toxicity was then assessed(More)
Acute, subchronic, and chronic toxicity studies were conducted in dogs with the new vasodilator/cardiotonic drug isomazole (IMZ) to support, in part, clinical investigations of this agent in humans. Single oral doses of IMZ of 25, 50, or 100 mg/kg given to English pointer dogs (2/dose) caused a marked drop in systemic blood pressure and reflex-induced(More)
LY-195115 is a new (investigational) inotropic agent. When given orally to either young adult rats or mice, single doses of 2500 or 5000 mg/kg were tolerated with minimal lethality. Clinical signs included muscle weakness, hypoactivity, and evidence of hemorrhage. Dogs and monkeys survived a single oral dose of 10 and 5 mg/kg, respectively; however, there(More)
Acute, subchronic, and chronic toxicity studies were conducted with isomazole, a new (investigational) inotropic agent with significant vasodilator properties. When given acutely to either young adult rats or mice, the oral median lethal dose was approximately 135 or 525 mg/kg, respectively. Clinical signs of toxicity were leg weakness, hypoactivity,(More)
Cadmium is a potent inhibitor of hepatic microsomal drug biotransformation in the rat. Male rats receiving a single intraperitoneal dose of cadmium exhibit significant decreases in hepatic microsomal metabolism of a variety of substrates. The threshold cadmium dose is 0.84 mg Cd/kg, and the effect lasts at least 28 days. Mechanistically, the inhibitory(More)
The repair of hernias through iliac crest defects is challenging secondary to the inherent weakness of the abdominal musculature and the rigidity of the pelvis. The defect is surrounded by inadequate tissue to properly buttress the repair. Full-thickness tricortical bone harvested from the iliac may result in an incisional hernia through the bony defect.(More)
A comparative study of the toxicity of the inotropic amines isoproterenol hydrochloride (IP), 1-norepinephrine bitartrate (NE), dopamine hydrochloride (DP), and dobutamine hydrochloride (DB) was conducted in beagle dogs (2/sex/dose group). All drugs were administered at doses that produced maximal contractile tension in dog myocardium. Doses, continuously(More)
