This preliminary study demonstrated the existence of a free radical generation during an experimental postischemic muscular reperfusion in a halothane anesthetized horse. The authors used alpha-phényl-N-tert-butylnitrone as a spin trap agent and the electronic paramagnetic resonance method to observe in vivo a free radical generation. 相似文献

Bacteriologic detection of Salmonella spp. from feces of animals admitted to Veterinary Teaching Hospital of the Faculty of Veterinary Medicine, University of Montréal, in Saint-Hyacinthe was carried out during a 1-year period to estimate the prevalence of bovine and equine salmonellosis. Prevalence at the time of hospitalization was quite low: 1.4% in cattle and 1.7% in horses. Incidence was 15.1 cases/100 animal/year in cattle and 38.7 cases/100 animal/year in horses. Serotype typhimurium was the most prevalent in both species. In cattle, cases were evenly distributed over the year. In horses, a recrudescence of cases and a obviousness of transmission were apparent in April 1996. 相似文献

Les électrolytes du sang et des sécrétions endométriales de la vache à la suite d'une glucocorticothérapie 下载免费PDF全文
The effect of two synthetic glucocorticoids, 9α-fluoroprednisolone acetate and dexamethasone (9α-fluoro, 16α-methylprednisolone) was studied on 12 normally breeding cows. Na, Mg, K, Ca and P concentrations were evaluated in the serum and in the uterine fluid at four stages of the estrous cycle.
No significant changes were noted in Na and Ca concentration in either serum or uterine fluid. On the other hand, significant changes in the Mg, K and P were observed. Both drugs have caused a decrease in the content of Mg in the serum (P<0.05) during diestrus, a fall in the level of uterine K (P<0.01) during proestrus and a decrease of P during proestrus both in serum (P<0.001 after dexamethasone treatment) and in uterine fluid (P<0.001 for both drugs).
It is obvious that the two drugs change the chemical composition of blood and endometrial secretions. This could jeopardize the survival of the spermatozoids and of the ovum as well as the fertilization and the implantation processes.

Étude Biochimique des Sécrétions Génitales de Femelles Bovines Infécondes qui Présentent des Cycles Oestrals Normaux 下载免费PDF全文
Exocervical samplings of 57 cows' genital secretions (30 normal reproducing and 27 repeat breeder cows) were studied during estrus. An attempt has been made to detect the following electrolytes: A1, Ca, Co, Cu, Fe, K, Mg, Mn, Na and Zn in these secretions. Ca, K, Mg and Na were found. No significant difference is noted in the Ca, K and Mg concentration (P>0.05) between the two groups, whereas a highly significant difference (P<0.001) in exocervical Na concentration has been measured between these groups. 相似文献

Utilisation du mélange lidocaïne-butorphanol en anesthésie épidurale caudale chez la jument. 下载免费PDF全文

Loss of rear motor control is the main limiting factor in the use of caudal epidural anesthesia in the horse. In man and laboratory animals, a small dose of an opiate combined with a local anesthetic enhances analgesia without impairing motor function. Thus, the amount of local anesthetic administered may be reduced. Butorphanol is an opiate widely used in horses. It has a good margin of safety and few cardiorespiratory effects. The effects of lidocaine (0.25 mg/kg) and lidocaine-butorphanol (0.25 mg/kg, and 0.04 mg/kg, respectively) were compared in 2 groups of 5 healthy unsedated mares. Horses in each group received either lidocaine or lidocaine-butorphanol in saline solution for a total volume of 0.0165 mg/kg. Epidural injection was performed at the first coccygeal interspace. Each mare was used only once. Cutaneous analgesia was assessed by a response to a pin prick; and visceral analgesia was assessed by response to a noxious stimulus applied to the urethra. Heart rate, respiratory rate, and arterial blood pressure were also measured. Analysis of the results showed an increase in duration of both cutaneous and visceral analgesia in the mares given lidocaine-butorphanol. Cutaneous analgesia increased from 36 +/- 13 to 150 +/- 21 min and visceral analgesia increased from 22 +/- 10 to 162 +/- 16 min. A cranial extension of the cutaneous analgesia was also observed. Cardiorespiratory depression or signs of excitation were not observed. However, these mares demonstrated peculiar walking in the hind limbs, not associated with signs of ataxia or hyperkinesia. 相似文献
