切屑卷曲的力学分析及其应用

在试验和理论分析的基础上，本文提出了复合卷曲的切屑比向上卷曲的切屑、当侧卷程度较大时比例向卷曲的切屑易于折断的观点，并且讨论了切屑产生复合卷曲及侧向卷曲的条件，这些对断屑槽的设计和使用有重要意义。

架子牛肥育综合技术研究

该文从架子牛的选购、驱虫、肥育期的饲养管理、日粮营养等方面做了系统的研究。结果表明,选择2～3岁的夏洛来牛或西门塔尔牛的改良后代,采用高能量高蛋白质日粮可以获得较高的经济效益。     

生、炒酸枣仁镇静催眠作用的比较研究

采用两种催眠试验方法,观察生、炒酸枣仁煎剂对阈下剂量戊巴比妥钠入睡的影响及对阈剂量戊巴比妥钠睡眠的影响.结果阈下剂量戊巴比妥钠的入睡试验中,不同炮制酸枣仁处理差异不明显;同一炮制中高剂量作用大于低剂量;在睡眠试验中亦获得类似的结果.结果表明:生、炒酸枣仁在同一剂量下药理作用无差异,但同种炮制存在一定的剂量效应关系.

黔东南土鸡不同醒抱方法的效果研究

为研究黔东南土鸡的醒抱方法，将刚进入抱窝状态的母鸡分成4个组，分别采用4种不同的醒抱方法进行试验。I组自然醒抱；Ⅱ组自由活动，加喂异烟肼；Ⅲ组采取隔离；lV组采取隔离，加喂异烟肼。结果表明：（1）醒抱时间：Ⅰ组、Ⅱ组和Ⅲ组、Ⅳ组比较，均差异极显著（P〈0．01）；Ⅲ组和Ⅳ组比较，差异不显著（P〉0．05）。（2）复产时...     

Laboratory tests for diagnosing and monitoring canine leishmaniasis

Although several reviews on canine leishmaniasis have been published, none thoroughly described clinicopathologic abnormalities and their clinical usefulness. The aim of this review was to provide information concerning current diagnostic tests relevant for clinical pathologists and from a practical perspective. Specifically, in canine leishmaniasis, nonregenerative normocytic normochromic anemia, thrombocytopenia, or leukogram changes may be present. Clinical chemistry and urinalysis may indicate renal dysfunction (azotemia, decreased urine specific gravity, proteinuria) and an inflammatory/immune response (increased acute phase proteins [APP] or α₂‐ and/or γ‐globulins). Although a potential gammopathy is usually polyclonal, it may also appear oligo‐ or monoclonal, especially in dogs coinfected by other vector‐borne pathogens. When lesions are accessible to fine‐needle aspiration (lymphoadenomegaly, nodular lesions, joint swelling), cytology is strongly advised, as the presence of Leishmania amastigotes in a pattern of pyogranulomatous inflammation or lymphoplasmacytic hyperplasia is diagnostic. If the cytologic pattern is inconclusive, the parasite should be identified by histology/immunohistochemistry or PCR on surgical biopsies. Alternatively, cytology and PCR may be performed on bone marrow samples where amastigotes, along with erythroid hypoplasia, myeloid hyperplasia, plasmacytosis, or secondary dysmyelopoiesis can be observed. Dogs with overt leishmaniasis generally have high antibody titers, while low titers predominate in immunologically resistant infected dogs or in exposed dogs with no parasite confirmation. Quantitative serology is recommended in clinically suspect dogs as high‐titer antibodies titers may confirm the clinical diagnosis. In confirmed and treated dogs, renal function and inflammatory/immune response variables should be periodically monitored.
