为研究裸花紫珠颗粒对靶动物犬血液生理生化指标的影响,该文将20只犬(中华田园犬)按完全随机方法分成4个组,每组5只,分别为第1组(空白对照组)、第2组(裸花紫珠颗粒0.1 g/kg·bw)、第3组(裸花紫珠颗粒0.3 g/kg·bw)、第4组(裸花紫珠颗粒0.5 g/kg·bw),采用口服给药的方法,每天给药1次,连续给药10 d,在试验期间观察试验犬临床体征表现,并评价不同剂量裸花紫珠颗粒对试验犬的体重和血液生理生化指标的影响。结果显示,试验犬口服不同剂量裸花紫珠颗粒连续10 d,临床体征表现正常,未见明显的影响,犬只血液生理生化指标与空白对照组相比无显著差异(P>0.05)。结果表明,裸花紫珠颗粒对试验犬只的临床体征、体重和血液生理生化指标无明显影响,安全性较好。 相似文献

旨在研究高温环境下佩戴犬降温马甲对德国牧羊犬运动前后生理生化指标的变化,掌握其变化规律,探讨该装备的作用效果,进而为该犬降温马甲的进一步研究提供理论基础。本试验以12只2~4岁,体重30~35 kg,健康的德国牧羊犬公犬作为试验对象,随机分为2组,每组6只,让试验犬在跑步机以15 km/h速度奔跑10 min,分别测定了试验犬在(33±1)℃,空气相对湿度62%下,运动前,运动后及运动后15 min后的体温、心率生理指标和血清生化指标,并对结果进行统计分析。结果显示:犬在跑步机以15 km/h速度奔跑10 min后,体温显著上升(P0.05),休息15 min后体温稍有恢复,仍然显著高于运动前,但3个阶段试验组比对照组皆体温稍偏低,试验组休息15min体温比运动后显著降低(P0.05);犬心率变化各组间均不显著(P0.05);犬血清肌酸激酶、血清乳酸脱氢酶浓度显著上升(P0.05),休息15 min后,各指标均有所恢复,但仍未恢复到运动前水平;其中,犬血清丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)浓度各阶段变化均不显著(P0.05)。结果表明,高温环境中德国牧羊犬短时间剧烈运动后体温明显升高,而佩戴降温马甲可稍降低犬体温的升高,并可加快运动后犬体温的恢复速度,降低高温环境下运动及训练对犬的危害,此研究为该犬降温马甲的进一步改进提供了理论基础。 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

以国际标准强毒R株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离MG,并收集感染鸡所产蛋分离MG。结果表明,人工感染48小时后上、下呼吸道及肺已被全面感染,96小时气囊已被感染,120小时输卵管已能分离到MG,卵巢始终分离不到MG。人工感染鸡自144小时便能在其所产蛋中分离出MG。药物治疗能在72小时内消除感染,油乳剂苗则需24天后逐渐降低蛋内MG分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内MG,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献
