The discrimination between wild and released Taiwan abalone Haliotis diversicolor was performed by stable carbon isotope analysis. Abalone samples were collected from Mao Aw Gulf in north-eastern Taiwan. Live abalone and dead shells were collected by divers with an 80 × 80 cm frame. The densities and amounts of wild and released abalone, as well as the survival rates of released abalone, in 1997 and 1998 were estimated. The age of the specimens was also determined from the specific temperature of each month and the inverse relationship between oxygen isotope values and temperatures. Results show that examining stable isotopic profiles proves to be a practical and feasible method for stock discrimination as well as density and abundance estimation. These data would be helpful in assessing the success of abalone culture and release programs, which aim to enhance this valuable marine resource. 相似文献

The radiographs of 60 cases of canine nasal neoplasia were reviewed. The dorso-ventral intra-oral view provided most information and the lateral view supplied supplementary detail. The most common changes were turbinate destruction rostrally and caudally, with a homogenous increase in radiopacity. Bilateral involvement was present in 38 cases. Absence (26) and thinning (7) of the vomer bone were found, as was deviation of the cartilaginous septum (11). Destruction of the maxilla or palatine bones produced radiolucencies which were superimposed on the increased radio-opacity in 17 cases. 相似文献

Controlled cross circulation (CCC) was performed in six pairs of dogs for 45 minutes with aortic cross clamping and cardioplegia. Data were collected in donor dogs at 10 minute intervals three times before, three times during, and three times after CCC and included arterial blood pressure, pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), cardiac index (CI), heart rate (HR), blood gas analysis, temperature, maximum rate of rise of left ventricular pressure dP/dt max/End diastolic volume (EDV), blood volume (BV), complete blood count (CBC) and activated clotting times (ACT). Pulse pressure (PP), systemic vascular resistance (SVR), oxygen delivery (Do2 ), and left ventricular cardiac work (LVCW) were calculated. Arterial blood pressure, CVP, blood gas analysis, temperature, BV, CBC, and ACT were measured in recipient dogs. During CCC, donor hemodynamic changes resembled those observed in models of acute onset arteriovenous fistulas. Insidious BV shifts can occur despite the use of occlusive roller pumps. After CCC, donor hemodynamics resembled acute blood loss, characterized by decreases in mean arterial pressure (MAP), CVP, PCWP, and CI, and increases in SVR and dP/dt max/EDV. These changes were probably caused by pump imbalance and BV shift to the recipient dog. 相似文献

Abstract— Giant cell dermatosisis is reported in six cats with evidence of concurrent feline leukemia virus (FeLV) infection. Scaling, crusting and alopecia, accompanied by pruritus, affected the head and/or face predominantly in most cats; generalized skin disease developed in one cat. Histologically, giant keratinocytes resembling syncytial cells were found in the epidermis and superficial hair follicles, and were accompanied by dyskeratosis, pustules and ulcers. Immunohistochemical staining revealed FeLV antigen in the giant cells and adjacent keratinocytes. FeLV infection may have led to neoplastic alteration of the keratinocytes through recombination with host oncogenes
Resumen Este artículo se basa en seis gatos con dermatosis de las células gigantes infectados con el virus FeLV. Éstos animales presentaban escamas y costras, así como pérdida de pelo y picor en las regiones de la cabera y cara, predominantemente. Tan solo uno de los gatos desarrolló una dermatosis generalizada. En el exámen histológico se demostró la presencia de keratinocitos gigantes con semejonza a las células sinticiales localizados en la epidermis y folículos pilosos superficiales, acompañados de disqueratosis, pústulas y ülceras. Las finturas histo-inmunológicas demostraron el antígeno FeLV en las células gigantes y keratinocitos adyacentes. La injeccion con el virus FeLV pudo haber conducido a la alteración neoplástica de los keratinocitos a través de la recombinación con los oncogenes del hospedador. 相似文献

Twenty-two cases of displaced upper femoral epiphysis in the dog have been reviewed with regard to the incidence, aetiology, radiographic and histological changes. The majority of the cases followed a severe traumatic episode but a significant number were associated with relatively trivial injuries. On histological examination necrosis of the epiphysis was common but the majority showed a rapid revascularization unassociated with collapse and deformity. The prevalence of the Labrador Retriever in the cases presented is noted. 相似文献

試驗証明温度和光对小麦品种抗条銹病性的影响极大。由于小麦品种对条銹菌不稳定反应所造成生理鑑定小种的困难,基本上可通过严格控制温度和光获得解决。条锈菌生理小种的鑑定最好在15℃恆温和恆光的設备下进行。用日光灯为光源,光強度保持4,000 Lux,每日照射16小时即已足够使小麦品种正常发病。 相似文献

This study was carried out to investigate the changes of orexin-A (OXA) and neuropeptide Y (NPY) expression in the hypothalamus of the obese and lean Zucker Diabetic Fatty (ZDF) rats which have a missense mutation in the leptin receptor gene. The mean body weights (MBW) between the obese and lean ZDF rats were significantly different at 28 and 70 postnatal days. However, at 14 postnatal day, there was no significant difference in the MBW between the obese and lean ZDF rats in both male and female. The OXA immunoreactivities were not significantly different between the obese and lean ZDF rats in both sexes at 14, 28, and 70 postnatal days, respectively. The NPY immunoreactivity was higher in the obese than in the lean ZDF rats in both male and female at 28 and 70 postnatal days, whereas there was no significant difference between the obese and lean ZDF rats at 14 postnatal day. These results indicate that both OXA and NPY might halt their roles for food intake in the obese phenotype of the male and female ZDF rats in the preweaning period of 14 postnatal day, whereas NPY might play a main role in the obesity of these rats in the weaning period of 28 and 70 postnatal days. 相似文献
