Lipid peroxidation initiated by free radical reactions is associated with tissue necrosis in a variety of conditions. We have measured serum lipid peroxide concentrations (as total thiobarbituric acid-reactive substances, TBARS) and creatine kinase (CK), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) activities and subjective muscle(More)
Previous studies have shown that surgical castration wounds take between 10 and 61 d to heal. The objectives of this work were to describe healing, inflammation, lying behavior, and serum concentration of substance P after surgical castration in beef calves and to evaluate the effect of a possible intervention, a single injection of flunixin meglumine (1.1(More)
OBJECTIVES The objective of this study was to evaluate the effect of megestrol acetate (Megace OS; Bristol-Myers Squibb, Princeton, NJ) on the oral food and fluid intake of nursing home (NH) residents under two conditions: usual NH care and optimal mealtime feeding assistance. DESIGN AND SETTING We conducted a prospective, preliminary trial in four NHs.(More)
Hot-iron branding is painful for cattle, but little is known about the duration of or effective methods to control this pain. This work quantified pain sensitivity and healing in branded and unbranded animals. In addition, the effects of a single injection of nonsteroidal anti-inflammatory drug (NSAID) were also considered; this has been suggested as(More)
A double-blind, parallel study was conducted comparing a new imidazole derivative, butoconazole nitrate, with placebo and miconazole nitrate for the treatment of vulvovaginal candidiasis. Patients were randomly assigned to six treatment regimens. Butoconazole was found to be an effective antifungal agent in both the six- and three-day treatment schedules.(More)
This study assessed the heart rate, breathing rate and behavioural responses of 12 juvenile Steller sea lions during hot-iron branding under isoflurane anaesthesia. Physiological and behavioural measures were recorded in four periods: baseline (five minutes), sham branding (one minute), branding (approximately 2.7 minutes) and postbranding (five minutes).(More)
