TRAUMATIC DURAL LACERATION IN A RACING GREYHOUND

Acute pelvic limb paralysis occurred in a racing Greyhound after a traumatic incident. During myelography, a dorsal laceration of the dura mater was detected at T_12–13. Immediate hemilaminectomy was performed at T_12–13, but neurologic status did not improve. At necropsy there was epidural and subdural hemorrhage at the T_12–13 interspace, and malacia and swelling of the spinal cord at that level. Intramedullary hemorrhage, malacia, and free fibrocartilaginous material characterized histopathology of the lesion. Possible mechanisms of the traumatic disk extrusion are discussed.     

THE USE OF ELECTROCARDIOGRAPHY IN THE DIAGNOSIS OF POOR RACING PERFORMANCE IN THE HORSE

Electrocardiograms were reocrded from 153 racehorses and 10 Olympic three-day-event horses. The horses were then grouped into those presented for routine examination, those in which there was a complaint of poor performance, those going to the Montreal Olympics, and those with upper respiratory tract abnormalities. When the ECGs of the four groups were compared on the basis of detection of abnormality, it was found that 93.2% of the poor performance group showed abnormalities of various types. The routine examination group showed 21.1% of horses with abnormal ECGs, and over half of these have been followed to the point where it can be said they raced unsuccessfully. In particular, this applied to those horses with T wave abnormalities in 4 or more leads, and to those with intraatrial block. There were significant T wave changes in 50% of the Olympic horses, and 43.7% of horses with laryngeal hemiplegia showed abnormality. While it can be concluded that T wave changes are highly significant findings in an ECG, it is also true that modification of the training programme is a way of helping trainers to get the best out of horses which might otherwise have a serious limitation of their performance potential.

电影中的暴力与音乐

暴力成为当代电影中出现最频繁的元素之一，暴力的表现在不同维度和层面上体现了创作者的意图。笔者从电影音乐的角度探讨音乐在暴力表现中的作用，并从视听结合的角度分析暴力的场面对音乐本身所起的反作用，试图从深层心理和接受层面探讨两者相互作用的原因。     

STUDIES ON THE PREVALENCE OF RINGWORM AMONG HORSES IN RACING AND BREEDING STABLES

A survey of 568 horses in training and 2,535 horses on breeding farms has shown 32 percent of the horses in training to be clinically affected while only 1.1 percent of breeding horses were affected with pathogenic dermatophytes. The majority of lesions on racing horses were located on the girth areas. Trichophyton equinum var. autotrophicum, M. canis and M. equinum were found to be restricted to racing horses only. M. gypseum occurred in racing, riding and breeding horses.
