CISTERNOGRAPHY COMBINED WITH LINEAR TOMOGRAPHY FOR VISUALIZATION OF THE PITUITARY GLAND IN HEALTHY DOGS A Comparison with Computed Tomography

Cisternography combined with linear tomography was performed in ten clinically healthy dogs (weighing 14-33 kg) to visualize the pituitary gland, and results were compared with the results from sagittal midline computed tomography (CT) in these dogs. With cisternography, the length of the pituitary gland of nine dogs ranged from 5.7 to 9.9 mm (mean ± SD, 7.9 ± 1.3), and the width from 5.4 to 8.7 mm (6.4 ± 1.0). With sagittal linear tomography following cisternography, the height of the pituitary gland of these nine dogs ranged from 4 to 6 mm (5.1 ± 0.7); and, with sagittal CT, it ranged from 4.3 to 6 mm (5.0 ± 0.6). In an 11-year-old female Greyhound, two small nodules were found at the periphery of the pituitary gland using cisternography but were not recognized on CT images. It is concluded that cisternography combined with linear tomography is a safe and accurate alternative for the visualization of the pituitary gland when CT is not available.     

Serum Fructosamine: A Reference Interval for a Heterogeneous Canine Population

Eighty-nine healthy dogs (44 males, 45 females) of different breeds, 1-12 years of age, living under varied feeding and environmental conditions, were sampled to evaluate a reference interval for serum fructosamine using a nitroblue tetrazolium photocolorimetric method. The analytical assay was evaluated by calculation of within-run and between-day variations. The results were approximately normally distributed and the calculated reference interval was 192.6-357.4 µmol/L (mean 275.0 µmol/L, standard deviation 41.2 µmol/L). No significant differences attributable to sex or age were observed. This reference interval is wider than those previously reported in less heterogeneous groups of dogs and in those from other geographical zones. The fructosamine values in serum from 3 diabetic dogs all exceeded the upper limit of the reference interval.     

Studies on the Occurrence of Peptococcus Indolicus and Corynebacterium Pyogenes in Apparently Healthy Cattle

A total of 1050 samples from apparently healthy cattle were examined bacteriologically with special regard to Pc. indolicus and Cb. pyogenes.Pc. indolicus was found in 58 % of 130 samples from tonsils (slaughterhouse material), in 23 % of 620 samples from the vagina of cows, in 22 % of 100 samples from the vagina of calves and heifers, in 5 % of 100 samples from the conjunctival sac of cows, and in 10 % of 100 samples from the nasal cavity of cows (Table 1). Cb. pyogenes was found in 51 %, 17 %, 19 %, 8 %, and 6 %, respectively. Both organisms were found in each of 9 herds examined, though with varying frequency (Tables 2, 3, and 4).Altogether Pc, indolicus was found in 254 (24 %) and Cb. pyogenes in 205 (20 %) of the samples examined (Table 1). In 127 samples both organisms were present. Eleven of the strains of Pc. indolicus were β-hemolytic, the rest non-hemolytic.By gel diffusion analysis the strains of Pc. indolicus as well as those of Gb. pyogenes could be identified with strains originating from pathological conditions in cattle. With Serotype B occurring most frequently, usually two or three different types of Pc. indolicus were found in each of the herds examined (Tables 5, 6, and 7).The investigation has shown that Pc. indolicus is widespread among healthy cattle, and given evidence to suggest that Pc. indolicus and Cb. pyogenes are natural cohabitants.     

我国细羊毛生产现状及思考

长期以来,我国细羊毛产业呈现出“三多一低”的情况,即绵羊养殖数量多,毛纺企业需求量多,羊毛进口量多,但是优质国产细羊毛自给自足率低。羊毛是我国长期依赖进口的大宗畜产品之一。与澳毛同级别的优质国毛(细度在70支以上)数量少,还远远达不到毛纺企业的需求。本文对国内外细羊毛产业现状进行了阐述,分析了目前我国细羊毛产业发展存在的问题,对我国细羊毛产业健康发展途径进行了一些思考。     

农村成人教育对培养农民健康消遣方式的重要性——基于湖北省襄樊市的调查

建设社会主义新农村是我国现代化进程中的重要历史任务。新农村建设的内容,包括农村物质文明和精神文明两方面的建设,两者缺一不可。农民健康消遣方式是农村精神文明建设的一个重要组成部分,而前者的培养离不开农村成人教育的发展。本文结合实地调查资料对我国目前农民农闲时间的消遣方式进行了分析,认为其具有选择的目的性不强、满意度不高、是否健康的判断标准模糊及农民希望改变消遣方式现状等方面的特点。

有益微生物在大海马健康养殖中的应用研究

实验用复合微生物由芽孢杆菌(Bacillusspp.)、红螺菌(Rhodospirillumspp.)、硝化细菌(Nitrobacterspp.)和硫化细菌(Thiobacillusspp.)组成,菌量比例分别为61.5%、27.3%、5.8%和5.4%。向大海马养殖池每10d使用1次,用量5mL/m3,菌液密度(2.0～2.5)×109/mL。结果表明,应用复合微生物的试验组溶解氧比对照组(不加菌)提高了32.7%,氨氮、亚硝酸盐和硫化物含量则分别降低了76.9%、97.1%和93.3%。对照池的浮游藻类优势种为蓝藻、甲藻和隐藻,分别占浮游植物总量的35.3%、22.3%和19.6%;试验池的浮游藻类优势种为绿藻和硅藻,分别占69.0%和26.8%,其藻类多样性指数比对照组增大了1.2倍。试验池的异养菌增长率为55.3%,而对照池的异养菌增长率达274.6%。试验期间,水温23～26℃,试验组的芽孢杆菌的数量从0.15×103CFU/mL急剧增至55.63×103CFU/mL,但对照组的仍保持在(0.13～0.38)×103CFU/mL的水平。而试验组弧菌数量比对照池的降低了2个数量级。
