Iodine content of commercially-prepared cat foods

Twenty-eight varieties of commercially-available cat food (23 canned, 5 dried) were analysed for iodine. The iodine concentration varied from less than 0.37 micromol/kg to 41.8 pmol/kg, wet weight (less than 1.48 micromol/kg to 167 micromol/kg, dry weight). Excessive or insufficient iodine intake or wide swings in iodine intake over prolonged periods may contribute to thyroid disorders in cats.     

美国山核桃在云南的引种表现及丰产栽培技术

美国山核桃(Carya illinoensis)，又名薄壳山核桃、长山核桃，为胡桃科，山核桃属落叶乔木，原产美国和墨西哥，是世界上重要的油料干果树种之一。目前全世界年产美国山核桃坚果18万t(仅为核桃105万t的1／6)，主产国美国(占世界产量70％左右)坚果售价3～8美元／kg；国内仅零星栽培，市场上很难看到销售，属珍稀干果。上世纪初首先由西方传教士引入我国栽培，近10年来，国家及云南等     

蛋鸡日粮添加绞股蓝粉对蛋品质的影响研究

试验选取健康、体重相近的京粉2号雏鸡300只,随机分为3组,每组100只。从1周龄开始,两个试验组日粮中分别添加0.5%、1.0%绞股蓝粉,对照组为空白对照,日粮不添加绞股蓝粉。饲喂至29周龄(产蛋高峰期)时进行蛋品质测定。结果显示:绞股蓝粉添加量为1.0%时,哈氏单位显著提高(P0.05),蛋黄胆固醇浓度显著降低(P0.05),蛋黄颜色(a)测定值极显著增加(P0.01);绞股蓝粉添加量为0.5%时,蛋重显著增加(P0.05);蛋黄颜色(b、L)测定值、蛋形指数、蛋黄比率和蛋壳厚度等指标在添加组与对照组之间无显著性差异(P0.05)。结果表明,在蛋鸡日粮中添加绞股蓝粉可以显著提高鸡蛋哈氏单位、加深蛋黄颜色、降低蛋黄胆固醇浓度、增加蛋重。     

约旦古城佩特拉“芝麻开门”的地方

1812年，一位西方探险家乔装打扮深入约旦西克峡谷，揭开了一座在历史上湮没了600多年的神秘古城的面纱。
　　西克峡谷是去佩特拉的必经之路，两面高耸的岩壁将古城隐没在峡谷中，长期的与世隔绝，留下了众多未解之谜。
　　建造卡兹尼神殿时，工程师并没使用传统的“从下到上”的建筑方式，却独辟蹊径，“从上到下”建造，颇具颠覆性意义。

Response of healthy dogs to infusions of human serum albumin

OBJECTIVE: To evaluate the clinical and immunologic response in healthy dogs to infusions of human serum albumin (HSA). ANIMALS: 9 healthy purpose-bred mixed-breed dogs. PROCEDURES: Each dog was administered a 25% HSA solution once or twice. Various physical examination and laboratory variables were serially evaluated. Antibody against HSA was assayed before and after infusion by use of an ELISA. Intradermal testing was also conducted. A repeated-measures ANOVA or Friedman repeated-measures ANOVA on ranks was used to compare results for the variables. RESULTS: Adverse clinical reactions were observed after the first or second infusion in 3 dogs. Anaphylactoid reactions were observed in 1 of 9 dogs during the first infusion and in 2 of 2 dogs administered a second infusion. Two dogs developed severe edema and urticaria 6 or 7 days after an initial infusion. All dogs developed anti-HSA antibodies. Positive responses for ID tests were observed in 8 of 9 dogs. Short-term increases were detected in blood protein, total bilirubin, and calcium concentrations after HSA infusion. Serum cholesterol concentrations and platelet counts decreased after HSA infusion. CONCLUSIONS AND CLINICAL RELEVANCE: Administration of HSA resulted in profound reactions in 2 of 9 dogs administered a single infusion and in 2 of 2 dogs administered a second infusion. This indicates that there is risk of life-threatening adverse reactions to HSA infusion in healthy dogs.     

Comparison of three methods of temperature measurement in hypothermic, euthermic, and hyperthermic dogs

OBJECTIVE: To assess the reliability and accuracy of a predictive rectal thermometer, an infrared auricular thermometer designed for veterinary use, and a subcutaneous temperature-sensing microchip for measurement of core body temperature over various temperature conditions in dogs. DESIGN: Prospective study. ANIMALS: 8 purpose-bred dogs. PROCEDURES: A minimum of 7 days prior to study commencement, a subcutaneous temperature-sensing microchip was implanted in 1 of 3 locations (interscapular, lateral aspect of shoulder, or sacral region) in each dog. For comparison with temperatures measured via rectal thermometer, infrared auricular thermometer, and microchip, core body temperature was measured via a thermistor-tipped pulmonary artery (TTPA) catheter. Hypothermia was induced during anesthesia at the time of TTPA catheter placement; on 3 occasions after placement of the catheter, hyperthermia was induced via administration of a low dose of endotoxin. Near-simultaneous duplicate temperature measurements were recorded from the TTPA catheter, the rectal thermometer, auricular thermometer, and subcutaneous microchips during hypothermia, euthermia, and hyperthermia. Reliability (variability) of temperature measurement for each device and agreement between each device measurement and core body temperature were assessed. RESULTS: Variability between duplicate near-simultaneous temperature measurements was greatest for the auricular thermometer and least for the TTPA catheter. Measurements obtained by use of the rectal thermometer were in closest agreement with core body temperature; for all other devices, temperature readings typically underestimated core body temperature. CONCLUSIONS AND CLINICAL RELEVANCE: Among the 3 methods of temperature measurement, rectal thermometry provided the most accurate estimation of core body temperature in dogs.
