... The present study addressed the causal role of Aleutian mink disease parvovirus (ADV) in acute interstitial pneumonia in mink kits. All the examined isolates of ADV caused interstitial pneumonia in newborn kits, although the severity of disease and the mortality varied. These findings indicate that ADV is the direct causal agent of this disease in mink kits and that cofactors, which could have bee ...
... Broilers previously exposed to high environmental temperatures (heat-acclimated) are more resistant to heat stress and consume more water during heat stress than nonacclimated controls. Two experiments were conducted to determine whether heat-acclimated broilers conserve body water by reducing urine and solute (Na) excretion. In the first experiment, renal function studies were conducted at an amb ...
... Brain glucose metabolism is impaired during hypoglycemia, but, if sustained, brain metabolism reverts to normal in animal models-data in man are lacking. We tested the hypothesis that adaptations occur to allow maintenance of normal rates of brain glucose uptake (BGU) following recurrent hypoglycemia in man. Twelve normal humans were studied over 4 days. On the initial day, arterial plasma glucose ...
... The effects of salts of propionic acid on newly hatched turkeys were examined. In Experiment 1, poults were injected with .25 mL of 1 M solutions of either sodium propionate or calcium propionate. After a 24-h holding period, the poults were killed and assayed for blood glucose, liver weight, and liver glycogen. Sodium propionate increased blood glucose concentration but did not alter liver weight ...
... Adrenoceptor-linked ⁴⁵calcium uptake was investigated in platelets from diabetic rats (hyperglycaemic, streptozotocin-induced, of 60 days duration). Basal uptake was markedly enhanced in platelets from diabetic rats compared with controls. However, whereas adrenaline-stimulated uptake was unchanged, isoprenaline-stimulated uptake was significantly reduced and noradrenaline-stimulated uptake signif ...
... Protein content and ion composition of host blood and feces from blood-fed adult cat fleas, Ctenocephalides felis (Bouche), were examined. Total fecal protein differed slightly from host blood indicating that there was little digestion of host blood by adult fleas. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels of host blood and flea feces also revealed little digestion, as evidenc ...

Abstract:
... The gene for black‐ear coat colour pattern, commonly found among cattle of tropical origin, was observed in 809 animals of four breeds of local cattle in southern China. Gene frequencies for Tf, Hb and Alb demonstrated that these groups of cattle were quite divergent from Bos taurus. These breeds of cattle are thought to be descended from ancient Chinese cattle. At the same time certain influences ...
