Ulceration and stricture of the right dorsal colon after phenylbutazone administration in four horses

Four cases of ulceration and stricture of the right dorsal colon were encountered. Ulceration of the right dorsal colon is generally associated with nonsteroidal anti-inflammatory drug (NSAID) toxicosis but there are few reports of stricture following ulceration. All four horses had recent phenylbutazone use: three had been given doses well in excess of the recommended dose and in one the dose was marginally above those recommended but was combined with administration of other NSAIDs. All four horses presented with intermittent low-grade colic, weight loss and ventral oedema. Diarrhoea was also seen in three of them. All had hypoproteinaemia due to severe hypoalbuminaemia, and hyperfibrinogenaemia. Hypoalbuminaemia was less severe in one horse and this horse was successfully managed medically. Two cases were definitively diagnosed at exploratory celiotomy and two at necropsy. Exploratory celiotomy was performed in two horses: one was euthanased at surgery and one was managed successfully with medical treatment and remained normal 1 year after surgery. Medical management included feeding of a low-roughage pelleted ration, corn oil, psyllium mucilloid, and discontinuation of NSAID administration.     

灰色系统理论在草坪草引种综合评估上的应用初探

应用灰色系统理论中的关联分析法对引种草坪草的返青期、绿化期、抗病性、越冬（夏）率、质地、频度、盖度、密度九项指标的主要性状平均值进行了分析评估，并探讨了灰色关联分析在草坪草引种综合评估中的应用。结果表明，根据各品种的灰色关联分析排序所得结果与品种的实际表现及专家鉴评排序结果是一致的。     

矮小型褐壳蛋鸡蛋白质和含硫氨基酸需要量的研究：II代谢试验和 …

将２７０只矮小型褐壳蛋鸡随机分为９组，饲喂９种不同蛋白质和含硫氨基酸水平日粮。９种试验日粮分别含有１１．５０ＭＪ／ｋｇ代谢能和１６．５２％、１７．２９％、１８．１７％粗蛋白质以及０．６２％、０．６６％、０．７２％含硫氨基酸，研究矮小型褐壳蛋鸡蛋白质和含硫氨基酸的需要量。代谢试验结果表明，４０周龄矮小型褐壳蛋鸡每日采食１４．１３ｇ蛋白质和０．５５８ｇＳ－氨基酸时，氮存留量达到最大值。血浆游离氨基酸测

A direct method for fatty acid methyl ester synthesis: application to wet meat tissues, oils, and feedstuffs

A simplified protocol to obtain fatty acid methyl esters (FAME) directly from fresh tissue, oils, or feedstuffs, without prior organic solvent extraction, is presented. With this protocol, FAME synthesis is conducted in the presence of up to 33% water. Wet tissues, or other samples, are permeabilized and hydrolyzed for 1.5 h at 55 degrees C in 1 N KOH in MeOH containing C13:0 as the internal standard. The KOH is neutralized, and the FFA are methylated by H(2)SO(4) catalysis for 1.5 h at 55 degrees C. Hexane is then added to the reaction tube, which is vortex-mixed and centrifuged. The hexane is pipetted into a gas chromatography vial for subsequent gas chromatography. All reactions are conducted in a single screw-cap Pyrex tube for convenience. The method meets many criteria for fatty acid analysis, including not isomerizing CLA or introducing fatty acid artifacts. It is applicable to fresh, frozen, or lyophilized tissue samples, in addition to oils, waxes, and feedstuffs. The method saves time and effort and is economical when compared with other methods. Its unique performance, including easy sample preparation, is achieved because water is included rather than eliminated in the FAME reaction mixtures.
