浙江省牛犬猝死症病原菌分离鉴定及其药敏试验

对浙江省 2 0 0 3年 3～ 4月发生的牛、犬猝死综合征 (sudden deathsyndrome ,SDS)的病原体进行了分离和鉴定 ,并检测了分离菌株对不同药物的敏感性。采集 2 6头牛、2 2头猝死犬的心血 ,以及心、肝、脾、肺、肌肉组织和粪便标本 ,并同时进行尸检。采用多种培养基分离培养病原菌。根据菌落特征、革兰染色镜检和ATB半自动细菌鉴定仪检测结果鉴定病原菌的种属。用药敏试条和ATB半自动细菌鉴定仪进行上述菌株对1 0种抗生素的体外药敏试验。从 84 .6 %病牛 (2 2 / 2 6 )、72 .7%病犬 (1 6 / 2 2 )中检出魏氏梭菌 (Clostridiumwelchii) ,但未检出炭疽杆菌 ,表明魏氏梭菌是牛、犬SDS的病原体。病牛真胃、小肠和心冠状沟 ,以及病犬小肠、肝脏出现明显的点状出血 ,这可能与其死亡直接相关。所分离的魏氏梭菌对青霉素和林可霉素耐药 ,但对其它 8种抗生素敏感 。

Anesthetic Management during Cesarean Section in English Bulldogs

The authors describe their experience with the management of the perioperative period, general anesthesia and the postoperative period in English bulldogs undergoing elective cesarean section and its effect on the neonates. The anesthetist for animals undergoing cesarean operation must be aware of any special needs, not only of the patient undergoing surgery, but also of the neonates. Anesthetic drugs administered to the pregnant patient will readily cross the placenta and affect them, with the exception of local anesthetics. Pregnant female patients are at increased anesthetic risk due to pregnancy-associated physiological alterations, such as altered pulmonary function. The anesthetist is often called to perform anesthesia on brachycephalic dogs for an elective cesarean section. Due to their conformation, these animals may have one or more anatomical abnormalities of the upper airways, which compromise the ability to ventilate adequately. The induction and recovery phases of anesthesia can be extremely dangerous in these patients, but the maintenance phase is generally fairly straightforward because the airways are controlled during maintenance In addition, vagal tone is frequently high and this can contribute towards significant bradycardia and further airway narrowing. All these reasons make general anesthesia in brachycepbalic dogs undergoing cesarean section rather complicated.

Effect of Chaiqinchengqi decoction on inositol requiring enzyme 1α in alveolar macrophages of dogs with acute necrotising pancreatitis induced by sodium taurocholate

OBJECTIVE: To investigate the effect of Chaiqinchengqi decoction(CQCQD) on inositol requiring enzyme 1α(IRE1α) in alveolar macrophages(AMs)of the dog model of acute necrotising pancreatitis(ANP) induced by sodium taurocholate.METHODS: Fifteen beagle dogs were randomised into a control group,ANP group and CQCQD group(n = 5 per group). ANP was induced by a retrograde duct injection of 50 mg/kg of 5% sodium taurocholate. The dogs in the control group received injections of the same volume of saline as the sodium taurocholate. After the models were induced,the dogs in the CQCQD group were administered 10 m L/kg CQCQD every 2 h for 6 h. Two hours after the last administration of either CQCQD or saline,they were sacrificed by anaesthesia. AMs were collected to determine the IRE1α and Interleukin-1β(IL-1β)m RNA and protein expression,and pancreatic tissues were collected for histopathology analysis.RESULTS: Compared with the ANP group,the m RNA and protein expression of IRE1α and the protein expression of IL-1β of AMs in the CQCQD group were significantly down-regulated,and the pancreatic histopathology score of the CQCQD group also was lower. There was no significant difference in the m RNA expression of IL-1β of AMs between the two groups.CONCLUSION: The CQCQD-induced down-regulation of the IL-1β protein expression may involve the down-regulation of the m RNA and protein expression of IRE1α in AMs.

再談中古漢語中“快”的相關詞語

在中古漢語(東漢—隋)中,'快'有'好'義。由'快'組成的複音詞'快牛''快犬(狗)''快馬',詞義是指好牛、好犬(狗)、好馬,非指跑得快的牛、犬、馬。本文通過這個案例説明,對一些常用詞的釋義,尤其是似是而非的用例中詞義的確定,很有必要對專書甚至斷代語料進行專門系統的調查分析,做出廣泛的排比歸納,這是避免釋義偏誤的一個有效途徑。
