Strain gauges were successfully bonded in vivo to the cranial, caudal, medial, and lateral aspects of the equine radium and tibia and to the dorsal, palmar, or plantar, medial, the lateral aspects of the metacarpus and metatarsus--all in the mid-diaphyseal region. Various activities were investigated, including walking, trotting or pacing, and standing up from anesthesia. The strain patterns showed that each stride produced a characteristic deformation cycle. The strains were measured and the axial loads were calculated as the horse performed certain activities. The tension band side of each bone was predicted from the results. The tension band sides of the metacarpus and metatarsus were the dorsomedial and dorsolateral aspects; for the radius and tibia, the tension band sides were the cranial and craniolateral aspects, respectively. 相似文献

我国野生动物所有权立法述评 总被引：10，自引：0，他引：10
野生动物所有权在野生动物保护事业中具有十分重要的地位,为此,我国先后制定了多部与野生动物所有权有关的法律法规,将野生动物所有权纳入法律调整的范围。但是受制定法律法规时各种条件的限制,目前我国野生动物所有权立法存在着一些不尽合理的地方,本文通过对我国野生动物所有权规范性法律文件的梳理,分析了立法方面存在的不足,并提出了立法建议。 相似文献

Equine herpesvirus 1 (EHV1) and equine herpesvirus 4 (EHV4) are important ubiquitous equine viral pathogens, causing much damage to the horse industry. EHV1 strains are associated with respiratory disease, abortion, and paresis/paralysis, whereas EHV4 strains are predominantly associated with respiratory disease. In the past decades much research effort has been put into improving knowledge about these viruses. In this paper the current state of knowledge of these viruses and the most important aspects of these virus infections, e.g. epidemiology, clinical aspects, pathogenesis and pathology, immunity, diagnosis, preventive management and management in the course of an outbreak and vaccination, is reviewed. Because we performed some research ourselves in the areas of diagnosis, epidemiology and vaccinology these aspects are reviewed in more depth than the other aspects. Still many questions have remained and new questions have risen. Consequently, research priorities should be made in an attempt to answer these questions. Therefore, this review ends with some personal recommendations for important priorities for future research. 相似文献

Haematogenous septic arthritis, physitis and osteomyelitis (SAPO) is a potentially debilitating or even life-threatening disease entity encountered in foals of all ages between birth and approximately 7 months old. Correct, and complete, diagnosis and successful treatment require collaboration between specialties including medicine, anaesthesia, diagnostic imaging, surgery and rehabilitation services. However, in order to succeed, it is important that all specialties have an overall knowledge of all aspects of the disease complex. Therefore, the aim of this review is to give an overview of aetiology, presenting complaints, clinical findings, diagnostic imaging, treatment, rehabilitation and prognosis. Part one deals with all aspects of aetiology and how to make a diagnosis. Part two deals with all aspects of treatment, rehabilitation and prognosis. 相似文献

Strain gauge rosettes were bonded to the dorsal, lateral, medial, and plantar aspects of the third metatarsal bone in the hind limbs of 6 ponies. The maximal compressive principal strain was approximately -600 X 10(-6) m/m, and exceeded the amplitudes of the tensile strains at all aspects of the bone. After transformation, the shear strain and the principal strains parallel and perpendicular to the bone were obtained. The first peak in the bending strain was higher in the dorsal and lateral aspects, and the second peak was higher in the medial and plantar aspects. Young modulus of elasticity was determined in a 4-point bending test at the dorsal and plantar sides; it averaged 19.5 GPa in tension and compression. Applying linear bending theory, the eccentricity of an axial force parallel or a bending force perpendicular to the bone were calculated. The position where the total force penetrated the tarsometatarsal joint surface was largely within the joint surface, indicating that the joint is merely loaded in (eccentric) compression. 相似文献

Most disease problems affecting farmed salmonid fish are either caused or exacerbated by bad husbandry and poor environmental conditions. The aspects of water quality and nutrition which are significant in causing husbandry problems are considered. The clinical aspects of these diseases are decribed in terms of the life cycle of salmonids, and methods of prevention are discussed. 相似文献

In this report we describe the first case of alveolar echinococcosis and leukemic malignant T-cell lymphoma in a dog presented to a general practice in the Netherlands. The owner and the dog moved from Switzerland to The Netherlands a few weeks before. The clinical aspects, diagnostics, pathology, therapy and public health aspects of this severe parasitic zoonosis are described. 相似文献
