Observations on hypoglycaemia associated with a hepatoma in a cat     

Thompson JC  Hickson PC  Johnstone AC  Jones BR 《New Zealand veterinary journal》1995,43(5):186-189

Disorientation, muscle fasciculations and weakness seen in a 12-year-old neutered female domestic shorthaired cat were attributed to hypoglycaemia associated with a large hepatoma. Glucagon tolerance tests on this cat and a healthy cat showed that their plasma glucose concentrations increased and decreased at about the same rate. Plasma insulin concentrations in the healthy cat increased and decreased in parallel with the plasma glucose concentration. In the affected cat, plasma insulin concentrations increased initially but decreased more rapidly. Reflecting these observations, the amended insulin to glucose ratios in the affected cat were much lower than those of the healthy cat, until the 4-hour sample. Serum somatostatin, somatomedin and gastrin concentrations were measured but no conclusions as to pathogenesis of the hypoglycaemia could be made. The alterations in insulin secretion in the affected cat suggested that altered hormonal control of glucose homeostasis may have occurred with this tumour.  相似文献

Effect of age and sex on the eviscerated yield,muscle and edible offal of a commercial broiler strain     

T. C. Grey  D. Robinson  J. M. Jones 《British poultry science》1982,23(4):289-298

1. Comparisons of the effects of age (up to 364 d) and sex on the rate of growth, eviscerated yield, blood loss and yield of skin, breast, thigh and drumstick muscles, heart, liver and gizzard have been made on a commercial British broiler strain.

2. Male broilers grew linearly up to 76 d whereas the females grew more slowly after 35 d. At 364 d the difference in live body weight was small.

3. Up to 56 d, males had a slightly higher eviscerated yield. There was no significant difference between the sexes beyond this age.

4. The proportional yield of breast muscle was variable with age, whereas that of thigh and drumstick increased with age in the male, particularly at 175 and 364 d.

5. After 35 d the proportion of skin was larger in females, whereas the gizzard as a proportion of live body weight in both sexes decreased rapidly between 21 and 76 d. Blood loss during killing was always higher in male broilers after 21 d.  相似文献

PERINATAL FOAL MORTALITY ASSOCIATED WITH A HERPESVIRUS     

R. J. Dixon  W. J. Hartley  D. R. Hutchins  E. E. Lepherd  Caroline  Feilen †  R. F. Jones  †  Daria N.  Love †  Margaret  Sabine † Anne L.  Wells † 《Australian veterinary journal》1978,54(3):103-105

An outbreak of perinatal foal mortality associated with a herpesvirus is described. Twenty two foals either were still-born, or died soon after birth, or were weak and soon developed severe respiratory signs, or were normal at birth and developed respiratory symptoms 18 to 24 hours later. Elevated temperatures, heart and respiratory rates were constant features. The animals were severely leucopaenic, and showed an absolute neutropaenia. At autopsy the lungs were enlarged, and showed varying degrees of aeration and moderate to severe oedema and congestion. Histopathology showed an acute focal necrotising bronchiolitis with the presence of intranuclear eosinophilic inclusion bodies. Herpesvirus was recovered from 9 foals in cell culture and identified by electron microscopy.  相似文献   

Skin blackening during the cooking of spent laying fowls     

T. C. Grey  D. Robinson  A. M. C. Davies  J. M. Jones 《British poultry science》1978,19(1):71-75

1. Blackening of the skin in factory processed cooked hens has been associated with elevated copper levels.

2. The degree of blackening was not directly related to copper content although the latter level was always higher than in control hens.

3. Simulated factory procedures, using scald water at 53 °C or 60 °C containing 50 mg Cu²⁺/1 and 50 mg C1₂/1, produced blackened skins of varying intensity on cooking.

4. It is suggested that the problem arose from a malfunction of the chlorination plant which produced excessive levels of chlorine and low pH, followed by erosion of copper from water pipes and subsequent interaction of copper and chlorine with the chicken skin.  相似文献   

Electrophoresis of avian muscle proteins     

Caroline C. L. Wilkinson  J. M. Jones 《British poultry science》1978,19(2):243-247

1. The electrophoretic patterns of water‐soluble proteins of avian muscle showed differences due both to species and to muscle type.

2. Each muscle pattern within a species showed a unique protein band which distinguished that species from other species.  相似文献   

Effects of female sex hormones on uterine motility and reactivity to oxytocin in goats.     

D E Jones  A Knifton 《Research in veterinary science》1975,18(3):288-293

Uterine motility was recorded for several weeks in 10 ovariectomised goats, using small intra-uterine balloons, to study the effects of female sex hormones on uterine activity and reactivity to oxytocin. Oestradiol stimulated uterine contractions and increased both the sensitivity and intra-uterine pressure response to oxytocin. When progesterone was administered in addition to oestradiol, spontaneous uterine motility became irregular with low amplitude contrations; the sensitivity and reactivity to oxytocin was significantly depressed.  相似文献
