Conservative management of minimally displaced radial fractures in three horses     

S. MATTHEWS  AJ DART  BA DOWLING  DR HODGSON 《Australian veterinary journal》2002,80(1):44-47

Minimally displaced, spiral, radial fractures were diagnosed in three adult horses. Two horses had open fractures and in one horse the fracture was closed. A diagnosis was made on radiographs taken 24 h, 5, and 9 days after the fracture. There was minimal displacement of the fracture fragments despite the considerable time which had elapsed between fracture and diagnosis and an unfavourable prognosis with internal fixation, so conservative therapy was the preferred method of treatment. One horse developed a sequestrum and draining sinus, which was treated surgically under general anaesthesia 3 months after diagnosis of the fracture. Other complications were minimal and transient. Two horses were being used for pleasure riding 12 months after fracture and one horse was pasture sound at 8 months.  相似文献   

QUANTIFICATION OF CEREBRAL VENTRICULAR VOLUME IN ENGLISH BULLDOGS     

Charles H.  Vite  DVM  Erik K.  Insko  PhD  MD  Helena M.  Schotland  MD  Karen  Panckeri  BA  Joan C.  Hendricks  PhD  VMD 《Veterinary radiology & ultrasound》1997,38(6):437-443

Quantitative measurement of cerebral ventricle volume of eight English bulldogs was performed using magnetic resonance (MR) imaging. The mean ventricular volume was 14.8 ml. with a range of 8.6 m1.-38.1 ml. The mean ventricular volume of two beagles was 2.2 ml with a range of 0.7 m1.3.7 ml. The percent of intracranial volume occupied by ventricle was found to be significantly larger in bulldogs (14.0%; S.D. = 7.9%) than in beagles (Range = 1.048%). The relationship between the percent of intracranial volume occupied by ventricle and measurements of body weight, age, sex, and various measures of skull anatomy of the bulldog was also determined. The relationship between ventricular volume and neurologic dysfunction was examined. There was a possible trend between high percent of intracranial volume occupied by ventricle and low body weight. This study will serve as a pilot study for examining the relationship between ventricular volume and neurologic disease in bulldogs.  相似文献   

地下水埋深对春玉米田土壤水分及产量的影响   总被引：17，自引：3，他引：17  

巴比江郑大玮  卡热玛·哈木提　孟翀王占生  邱江泉 《水土保持学报》2004,18(3):57-60,65

通过6种地下水位控制处理和对照春玉米试验,探讨了地下水埋深对春玉米农田土壤水分、产量以及水分利用效率的影响。结果表明,地下水埋深对春玉米0～100cm层次土壤水分的影响较大。地下水位越浅这种影响显得越明显;无论地下水埋深深浅,田间累计地下水补给量变化规律可分为4个阶段,即稳定增长期、缓慢增长期、快速增长期和趋于稳定期。地下水位越高,累计地下水补给量越大,土壤排水量越大。较大降雨后土壤开始排水日期随着地下水埋深加深而滞后;地下水埋深1.0m时春玉米产量和水分利用率最高。地下水位在1.0m以下时,水分利用效率随地下水位加深而减少。  相似文献

2003~2004年在山东省滨州市沾化县、无棣县等冬枣产区调查发现,冬枣生长前期在枣吊和叶片上发生了一种细菌性新病害。通过对典型病害样本进行病原菌分离、纯化获得20个菌株。从中选出4个菌株进行致病性测定,同时对其细菌形态、培养性状、染色反应、生理生化测定及血清学反应等性状进行了较为系统研究。结果表明,该地区冬枣溃疡病是由油菜黄单胞Xanthom onas campestrisPamm e(Dowson,1939)侵染引起的。  相似文献   

Probing the Local Effects of Magnetic Impurities on Superconductivity     

A Yazdani  BA Jones  CP Lutz  MF Crommie  DM Eigler 《Science (New York, N.Y.)》1997,275(5307):1767-1770

The local effects of isolated magnetic adatoms on the electronic properties of the surface of a superconductor were studied with a low-temperature scanning tunneling microscope. Tunneling spectra obtained near magnetic adsorbates reveal the presence of excitations within the superconductor's energy gap that can be detected over a few atomic diameters around the impurity at the surface. These excitations are locally asymmetric with respect to tunneling of electrons and holes. A model calculation based on the Bogoliubov-de Gennes equations can be used to understand the details of the local tunneling spectra.  相似文献
