LONG-TERM FOLLOW-UP OF HYPERTHYROID CATS TREATED WITH IODINE-131

A long-term follow-up study of hyperthyroid cats treated with iodine-131 was conducted at the Texas A&M University Veterinary Teaching Hospital. Between January 1985 and December 1990, 255 cats were treated. Basic demographic data, information on treatment, and diseases at the time of diagnosis were recorded. Two hundred and thirty seven cats had long-term follow-up data collected by telephone interviews with the referring veterinarian and/or the owner on outcome of therapy, diseases that developed during the follow-up period and survival. Risk for developing hyperthyroidism was highest for cats greater than 10 years of age. There was no breed predisposition. Neutered cats were slightly over-represented among the cases compared to intact animals. Eighty-five percent of treated cats became clinically normal and remained euthyroid for a median time of 17.5 months. Four percent remained hyperthyroid and 9% became hypothyroid, requiring thyroid hormone supplementation.

RADIOGRAPHIC DIAGNOSIS OF GASTROINTESTINAL DISORDERS IN THE FOAL

Abdominal discomfort in the foal presents a diagnostic challenge, because the small size of the foal precludes rectal palpation. Standing lateral horizontal beam abdominal radiographs using conventional techniques were evaluated as a diagnostic aid to identify the presence and location of gastrointestinal disorders in foals presented with colic. Forty foals were radiographed prior to surgery (20 foals), necropsy (7 foals), or clinical diagnosis (13 foals). Clinical, surgical, or necropsy findings were then correlated to radiographic findings. Gastrointestinal disease was accurately identified on radiographs as the source of colic in 25 of 26 foals that had surgical or postmortem confirmation. The site of disease, whether gastric, small intestinal, large intestinal, or a combination, was accurately determined from radiographs. Standing lateral abdominal radiographs were determined to be a valuable diagnostic aid in the foal presented with colic.     

储罐罐顶的失稳分析

针对油罐罐顶的失稳问题，从影响罐顶稳定性的原因和校核两个方面，对光球壳和加筋球壳两种罐顶结构进行了分析，列举了罐顶外荷载和罐顶稳定性校核公式，总结了罐顶失稳分析的步骤和方法，对几起典型的罐顶失稳实例进行了研究，指出罐顶外载荷超载、罐顶板腐蚀减薄、安装制造质量的缺陷是导致罐顶失稳的重要原因。     

Transmission of some species of internal parasites in horses born in 1993, 1994, and 1995 on the same pasture on a farm in central Kentucky

Data are presented on the last 3 years of a 7-year study (1989–1995) on transmission of natural infections of internal parasites in horse foals (n = 27) born in 1993, 1994, and 1995 on the same pasture on a farm in central Kentucky. The foals were in a closed breeding herd of horses. Research on the first 4 years (1989–1992) of the study was published earlier (Lyons et al., 1991, 1994). Thirty-five species of endoparasites were identified, including 24 species of small strongyles. Monthly, seasonal, and host-age transmission patterns were elucidated for the parasites. Comparison of data between the first 4 years and last 3 years of the study indicates similarities, but also differences, including an increase in prevalence and numbers of Thelazia lacrymalis and Anoplocephala perfoliata.     

PUF树脂胶粘剂及其在竹帘胶合板上应用的研究

以竹胶合板用酚醛树脂合成工艺为基础，按不同的尿素与苯酚摩尔比．合成一系列苯酚-尿素-甲醛共聚型树脂胶粘剂（PUF），并用该系列胶粘剂难制竹帘胶合板．通过对竹帘胶合板进行性能检测和检测结果分析．表明随尿素与苯酚摩尔比的增加，竹帘胶合板的力学性能总体呈下降趋势，但对静曲强度、弹性模量和冲击强度的影响不显著，对保存强度有很大的影响，将尿素与苯酚的摩尔比控制在0．5以下时．产品可以达到国家相关标准的要求．
