In six experimental dogs, arthrographic quality and synovial inflammatory response with shoulder arthrography comparing meglumine-sodium diatrizoate (Urovison) and the monoacidic dimer, meglumine-sodium ioxaglate (Hexabrix) was evaluated. In our study initial films were of equally high diagnostic quality for both contrast media, but delayed films significantly favored ioxaglate for diagnostic quality. The rise in white blood cells in synovial fluid samples collected 24 hours after the arthrographic procedure was significantly lower after the use of ioxaglate. Histologic examination performed 14 days after the intra-articular injection revealed no drug related lesions. 相似文献

Summary Reproduction and lamb production of three fat-tailed, carpet-wool Iranian breeds of sheep; Karakul (130 ewes), Mehraban (103) and Baluchi (119) were studied. The ewes were mated either as purebreds or with Corriedale or Targhee rams. The overall least-squares means for ewes mated (showed oestrus) or ewes exposed, ewes lambed or ewes mated, lambs born of ewes lambing (prolificacy), lambs born alive of total lambs born, lambs weaned of live lambs born, lambs weaned (75 days of age) of ewes mated, kg lamb weaned per ewe mated and kg lamb weaned per 100 kg ewe mated were 98.3%, 93.5%, 103.1%, 94.9%, 97.8%, 90.0%, 18.2 kg and 38.4 kg respectively. The native breeds were not different for any of the traits studied except for prolificacy which was higher in Mehraban than in Karakul. Purebred matings did not differ from the crossbred matings for any of the traits concerning the number of lambs but crossbreeding improved kg lamb weaned per ewe mated (9.2%, P=0.08) and kg lamb weaned per 100 kg ewe mated (10.0%, P<0.05). Among the three native breeds Karakul showed the largest improvement when crossed with the exotic rams for the traits concerning kg lambs weaned. Corriedale and Targhee rams had similar effects on all the traits studied. A lower percentage of virgin ewes showed oestrus, had a lower twinning rate and productivity compared with the mature ones. Sex was not a significant source of variation in lamb livability.
Desempeño Reproductivo De Tres Razas Cola Gruesa De Ovejas Apareadas Con Moruecos Nativos, Corridale Y Targhee
Resumen Se estudiaron la reproducción y producción de corderos iraníes de tres razas fat-tailed (Cola gruesa o grasosa) productores de lana para carpetas: Karakul (130 ovejas), Mehraban (103) y Baluchi (119). Las ovejas fueron apareadas como puras, o con moruecos Corridale o Targhee. Las medias mínimas cuadradas para ovejas apareadas (que mostraron estro) de ovejas expuestas, ovejas paridas de ovejas apareadas, corderos nacidos de ovejas paridas (prolificidad), corderos nacidos vivos del total de corderos nacidos, corderos destetados de corderos nacidos vivos, corderos destetados (75 días de edad) de ovejas apareadas, kg de cordero destetado por oveja apareada y kg de cordero destetado por 100 kg de oveja apareada, fueron: 98.3%, 93.5%, 103.1%, 94.9%, 97.8%, 90.0%, 18.2 kg y 38.4 kg respectivamente. Las razas nativas no fueron diferentes en ninguna de las características estudiadas, excepto por le prolificidad la cual fue mayor en Mehraban, que en Karakul. El apareamiento de razas puras, no difirió de los apareamientos cruzados para cualquiera de las características estudiadas concernientes con el número de corderos, pero el cruzamiento mejoró los kg. de cordero destetado por oveja apareada (9.2%,p<0.08) y kg de cordero destetado por 100 kg de oveja apareada (10.0%,P<0.05). De las tres razas nativas, la Karakul fue superior cuando se cruzó con las razas exóticas en lo concerniente a las características kg de cordero destetado. Las razas Corriedale y Targhee tuvieron efectos similares en todas las características estudiadas. Un bajo porcentaje de ovejas vírgenes ciclaron regularmente, tuvieron un porcentaje bajo de mellizos y productividad en general, comparada con las ovejas maduras. El sexo no fue una fuente significativa de variabilidad, en la supervivencia de los corderos.
Performances De Reproduction De Trois Races De Moutons À Queue Grasse Accouplées À Des Locales, Corriedale Et Targhee
Résumé La reproduction et la production d'agneaux de 3 races iranienes à queue grasse élevées pour la production de laine à tapis: karakul (130 brebis), Mehraban (103) et Baluchi (119) furent étudiées; Les brebis furent accouplées soit en race pure soit avec des béliers Corriedale ou Targhee; Les moyennes estimées par la méthode des moindres carrés de l'ensemble des brebis accouplées (oestrus visible) par rapport aux brebis exposées; des brebis agnelant par rapport aux brebis accouplées, des agneaux nés par rapport aux brebis agnelant (prolificité); des agneaux nés vivants sur les nés totaux, des agneaux sevrés sur les nés vivants, des agneaux sevrés par brebis accouplée, et du kg d'agneau sevré par 100 kg de brebis accouplées étaient 98,3%; 93,5%, 103,1%, 94,9%, 97,8%, 90,0%, 18; 2 kg et 38,4 kg respectivement. Les races natives n'étaient pas différentes pour les autres caractères étudiés excepté pour la prolificité qui était plus élevée en Mehraban qu'en Karakul. Les accouplements en race pure ne différaient pas des croisements pour tous les caractères concernant le nombre d'agneaux mais le croisement améliorait les kg d'agneaux sevrés par 100 kg de brebis accouplée (9,2%P=0,08) et les kg sevrés par 100 kg de brebis accouplée (10,0%P<0,05). Parmi les 3 races natives, la Karakul montrait l'amélioration la plus grande lorsque croisée avec les béliers exotiques pour les caractères concernant les kg d'agneaux sevrés. Les béliers Corriedale et Targhee avaient des effets similaires sur tous les caractères étudiés. Un plus faible pourcentage de brebis vierges à oestrus visible, avait un plus faible taux de jumeaux et de productivité comparé aux brebis matures. Le sexe n'était pas une source significative de variation dans la viabilité des agneaux.相似文献

微管、微丝特异性抑制剂处理对水稻抗病性的影响 总被引:3,自引:0,他引:3
微管特异性抑制剂oryzalin、微丝特异性抑制剂细胞松弛素A (cytochalasin A,CA)和细胞松弛素D (cytochalasin D,CD)的试验表明:oryzalin在5~50μmol/L、CA在0.5~1.0μg/mL、CD在1~20μg/mL的浓度范围内,对稻瘟病菌孢子的萌发和附着胞的形成基本上没有影响。采用以上几种细胞骨架特异性抑制剂处理水稻叶鞘都可以不同程度地抑制寄主细胞抗病菌扩展的能力。在抑制剂处理的水稻叶鞘细胞中,病菌扩展的速度加快。进一步的观察发现,抑制剂处理抑制水稻细胞抗病菌的扩展能力与水稻的抗病防卫反应如原生质颗粒化、多酚类物质的积累和HR发生的延迟是相关的。 相似文献

In recent years, the interest in equine foetal gender determination (FGD) during gestation increased remarkably. Ultrasonographic FGD can be performed in two different periods during gestation. The earliest examination can take place at a gestational age of 60–70 days, whereby the genital tubercle is used to differentiate between male and female foeti. The time window of the second approach is wider (120–210 days), and there are more characteristics to take into consideration. In this article, the feasibility and accuracy of ultrasonographic FGD in mid‐ to late gestation are evaluated. One hundred twenty‐one mares from different breeds with a pregnancy stage between 120 and 270 days were examined once, using B‐scale ultrasonography (Esaote MyLab™ClassC). None of the mares were sedated nor shaved, and the procedure was completed within 15 min. Diagnosis was firstly based on the gonads. The final judgement was made based on all visible foetal reproductive organs. In three cases with a pregnancy stage beyond 257 days, FGD was not possible. All of the examined mares in which a FGD could be performed gave birth to a healthy foal. In 98% of the examinations (116/118), the diagnosis was correctly made. In both cases of misdiagnosis, only one characteristic was seen during the procedure and wrongly interpreted. Beyond 210 days of pregnancy, the extremities can preclude a good visualization of the inguinal region. In conclusion, equine FGD in mid‐ to late gestation is an accessible and accurate technique, although a good ultrasound device is a prerequisite and experience and expertise is necessary. 相似文献

Fish associations with different types of littoral habitats were studied in four canyon‐shaped reservoirs in the Czech Republic in years 2010 and 2011 by gillnets. Two to three habitats per reservoir–beaches (former meadows), stump fields (former forest) and rubble slopes–were defined and sampled along the longitudinal axis of reservoirs. Effects of reservoir, habitat and locality (position along longitudinal axis) on fish biomass, abundance and species structure were tested for juvenile and adult fish separately. Hierarchical analysis of variance revealed that habitats differed significantly in fish biomass and abundance. Redundancy analysis showed that analysed environmental variables had significant influence on fish community structure. Most variability in community structure was explained by reservoir and then by combination of habitat and slope steepness. Locality position had the smallest influence on community structure. For both adult and juvenile fish total abundance and biomass, the most inhabited habitat was beaches; rubble slopes were the least inhabited. Habitat associations differed among species. Among adults, bream Abramis brama, white bream Blicca bjoerkna and roach Rutilus rutilus were associated with beaches and stump fields, whereas perch Perca fluviatilis, ruffe Gymnocephalus cernuus, asp Aspius aspius and pike Esox lucius were associated with rubble slopes. Bream, white bream, bleak Alburnus alburnus, roach, ruffe and pikeperch Sander lucioperca were associated with beaches among juveniles, whereas the only juvenile associated with rubble slopes was perch. We showed that most common species are associated with distinct habitats and also that utilisation of various littoral habitats differs in general. 相似文献
