Cryptococcal osteomyelitis in a dog

Osteomyelitis caused by Cryptococcus neoformans was diagnosed in a three-year-old male Irish wolfhound. The case details and radiological findings of radiolucency and periosteal reaction of the left third metatarsal bone had lead to an initial diagnosis of a malignant bone tumour. Biopsy revealed a fungal granuloma and culture identified the causal organism. A four month course of ketaconazole was instigated and the lameness resolved. Twelve months after the end of treatment there was no recurrence of the problem.     

聚丙烯酰胺凝胶电泳法鉴定禽呼肠孤病毒

从感染禽呼肠孤病毒的细胞中,以SDS和酚提取病毒核酸,通过聚丙烯酰胺凝胶电泳(PAGE)法将分节段的核酸分开,经银染色显示,呈3-3-1-3分布,此法可用于禽呼肠孤病毒的快速检测、鉴定。同样方法未能使传染性法氏囊病毒核酸显示。     

Genotypic Variability in Biomass Protein and Nucleic Acids in Four Linum Species to Sodicity Stress

Differences in gas exchange parameters i.e. carbon exchange rate (CER), transpiration (Tr), water vapor conductance (g) were investigated, under a controlled environment, in a semi-dwarf (SD) Triticum aestivum line, its tall (TL) near isoline and the Payne (PA) variety characterized by small leaves. The plants were maintained in: (a) optimal substrate moisture condition (CTR); (b) salinized by watering with a 0.12 m NaCl solution (SLT); (c) water stressed by withholding waterings during a period of six days (STR); (d) stressed and salinized during the same period and with the same saline solution (S + S). CER and Tr were negatively affected by the stresses; SLT and S + S treatments had a higher WUE compared to their respective controls CTR and STR.
SD line had a better performance in terms of CER and WUE, particularly when water and salt stresses interacted. Leaf anatomy and assimilation/internal CO₂ concentration curves contributed to explaining the SD performance.     

芫花萜药膜中止早,中孕412例效果分析

芫花萜膜终止早中孕４１２例临床观察的结果表明，对孕１２～１６周的流产成功率为９０．８％，给药至排胎平均时间为２３．４６±１０．３２小时，产时、产后失血平均分别为７１．８７±３３．５６ｍｌ和４５．１７±２０．５８ｍｌ。整个流产过程宫缩缓和，极少强直性宫缩，节律良好，痛苦少，类似正常分娩过程，可作为终止１２～１６周妊娠可供选择的一种有效方法。     

Antibody response to crustacean ectoparasites in rainbow trout, Oncorhynchus mykiss (Walbaum), immunized with Argulus foliaceus L. antigen extract

Abstract. A humoral antibody response was demonstrated by ELISA in rainbow trout immunized intraperitoneally with extracts from the branchiuran ectoparasite Argulus foliaceus. A similar immunization protocol produced a higher titre response in a rabbit. Both trout and rabbit identified several antigenic components on immunoblots. ELISA and immunoblotting indicated that rainbow trout and rabbit anti-A. foliaceus sera identified components from the parasitic copepods Lepeophtheirus salmonis and Caligus elongatus.     

交沙霉素等四种药物对雏鸡隐孢子虫病的预防效果

对经口感染(4.0×10~5个/鸡)贝氏隐孢子虫(Cryptosporidium baileyi)卵囊的雏鸡在其饲料中分别添加交沙霉素(4.0g/kg)、复方新诺明(4.9g/kg)、大蒜素(400mgkg/)、甲硝唑(2.0g/ks),任鸡自由采食,连用7d.结果表明,实验鸡潜隐期延长,粪中卵囊数显著降低,体重明显增加,血液学值及血清酶学指标与健康对照鸡无明显差异.由此证明,这4种药物对实验性雏鸡隐孢子虫病有不同程度的预防作用.
