Biological and imaging characteristics and radiation dose rates associated with the use of technetium-99m-labelled imidodiphosphate in the horse.          下载免费PDF全文

L J Riddolls  G G Byford    S L McKee 《Canadian journal of veterinary research》1996,60(2):81-88

The biological and imaging characteristics of technetium-99m imidodiphosphate (Tc99m-IDP) were measured in 4 horses once and in 1 horse twice. All computational results are expressed with 95.5% (mean +/- 2 SD) confidence limits. The clearance half-time of the radiopharmaceutical from the blood was 29.6 +/- 2.3 min. The percentage of the administered dose circulating in the whole-blood volume at 4 h was 3.9 +/- 0.8%. The Tc99m-IDP radioactivity confined at the plasma fraction of the whole blood at 4 h was 85.3 +/- 1.6%. At 8 h, approximately 45 +/- 16% of the dose administered had been excreted via the urine. The mean effective half-time of the urine activity concentration was 1.1 +/- 0.3 h. The ratios of bone-to-soft tissue activities increased with time postinjection. Urinary radioactivity concentration measurements and radiation dose rate measurements immediately behind the elbows were analysed and it was determined that 24 h is an appropriate radioisolation time for mature horses administered 3.7 GBq (100 mCi) Tc99m-IDP.  相似文献   

Treatment with ivermectin of sarcoptic mange in pigs     

JT SEAMAN  DR THOMPSON†  RA BARRICK‡ 《Australian veterinary journal》1993,70(8):307-308

Ivermectin injectable solution (1% w/v) was highly effective against Sarcoptes scabiei var suis when administered subcutaneously once to swine at 300 mcg/kg body weight. There were significantly (P < 0.05) fewer Sarcoptes mange mites counted on pigs treated with ivermectin than on untreated pigs at each count up to day 56 after treatment. The results indicate ivermectin should provide an efficient, practical means of control of sarcoptic mange in intensive piggeries.  相似文献

Assessment of the resistance of potato varieties to common scab     

R. K. McKee 《Potato Research》1958,1(1):65-80

Summary Field and glasshouse methods of assessing the resistance of potato varieties to common scab were investigated and procedures which were found to give satisfactory results are described in detail. Estimates of resistance for individual varieties in the two environments were closely correlated. Examination of a number of isolates ofStreptomyces scabies showed that these varied greatly in virulence but no evidence of physiological specialisation was found.

Zusammenfassung Feld- und Gew?chshausmethoden zur Feststellung der Resistenz von Kartoffelsorten gegen Schorf wurden untersucht. Verfahren, die zufriedenstellende Resultate ergaben, sind in Einzelheiten beschrieben. Die Sch?tzungen der Resistenz bei den einzelnen Sorten in den beiden Umgebungen standen in enger Wechselbezichung zu einander. Die Prüfung einer Anzahl Absonderungen vonStreptomyces scabies ergab, dass diese in Virulenz stark variierten; aber es wurde kein Fall von physiologischer Spezialisierung gefunden.

Résumé Des méthodes d'évaluation de la résistance à la gale commune de variétés de pommes de terre ont fait l'objet d'investigations en plein champ et en serre, alors que les modes opératoires donnant des résultats satisfaisants, ont été décrits en détail. Une corrélation étroite a été établie entre les estimations de la résistance pour chacune des variétés distinctes, placées dans les deux ambiances. L'examen de quelques cas isolés deStreptomyces scabies a démontré une grande variation dans la virulence sans qu'une preuve de spécialisation physiologique ne fút fournie.

Differential Expression of IGF Family Members in Heat‐Stressed Embryos Produced In Vitro from OPU‐Derived Oocytes of Nelore (Bos indicus) and Holstein (Bos taurus) Cows     

RA Satrapa  EM Razza  ACS Castilho  RAL Simões  CF Silva  T Nabhan  MF Pegorer  CM Barros 《Reproduction in domestic animals》2013,48(6):1043-1048

The IGF system is related to embryo quality. We aim to determine the effect of the heat stress on the mRNA expression of IGF1 and IGF2, IGFR1 and IGFR2, IGFBP2 and IGFBP4, and PAPPA in in vitro production (IVP) blastocysts from Nelore and Holstein after ovum pick up (OPU) to better understand the differences between these breeds. Oocytes from four Nelore and seven Holstein were collected in six OPU sessions. Following in vitro maturation and fertilization using six Nelore or Holstein sires, embryos were divided into control (cultured at 39°C) and heat stress (HS; exposed to 41°C for 9 h). Blastocysts were submitted to RNA extraction. The IGF1 expression was higher in blastocysts under HS in both breeds, and the expression of IGFBP2 and IGFBP4 was higher in Holstein blastocysts under HS. The high PAPPA expression and the low expression of IGFBP2 and IGFBP4 are associated with a more efficient degradation of IGFBPs, which results in greater IGF bioavailability in Nelore blastocysts and may contribute to the superior HS tolerance in Nelore, when compared to Holstein.  相似文献   

Oxygen Deficiency in Spartina alterniflora Roots: Metabolic Adaptation to Anoxia     

Mendelssohn IA  McKee KL  Patrick WH 《Science (New York, N.Y.)》1981,214(4519):439-441

The aerenchyma (air-space) tissue in the wetland macrophyte Spartina alterniflora conveys sufficient oxygen to roots for predominately aerobic respiration in moderately, but not highly, reduced substrates. Continuously flooded plants survive by respiring anaerobically, although growth is decreased. Two metabolic adaptations to flooding are displayed in this species, depending on the degree of soil reduction.  相似文献
