Enzyme and glycogen structure studies have been carried out on tissues of a glycogenotic dog, the clinical and pathological characteristics of which are reported in the accompanying paper. Liver glucose-6-phosphatase, leukocyte and liver acid maltase, and liver and skeletal muscle glycogen Phosphorylase all appeared largely unaffected. The activity of the muscle and liver debranching enzyme (amylo-l,6-glucosidase), determined by two independent assay methods, was, however, reduced to between 0 and 7 % of normal activity. Glycogen structure studies with Phosphorylase or iodine spectra revealed that the abnormally large amounts of glycogen found in liver and skeletal muscle had abnormally short branches, as would be expected for a deficiency of debranching enzyme. It is thus clear that the dog had suffered from the equivalent of Cori's disease (limit dextrinosis, type III glycogen storage disease). Preliminary data indicate that it may be possible to identify heterozygotes based on a study of the debranching enzyme of leukocytes. 相似文献

Kim Ki-duk's 2001 film Address Unknown presents a political allegory of modern Korea by referencing past traumas through local characters set in a U.S. military base town in 1970. The physical and emotional scars of past violence reveal current victimization re-enacting social injustice. Cold War militarism and the U.S. presence shatter the lives of three young people and the community as they internalize the destruction of their lives. 相似文献

The serum or plasma biochemical profile is essential in the diagnosis and monitoring of systemic disease in veterinary medicine, but current reference intervals typically take no account of breed-specific differences. Breed-specific hematological phenotypes have been documented in the domestic dog, but little has been published on serum biochemical phenotypes in this species. Serum biochemical profiles of dogs in which all measurements fell within the existing reference intervals were retrieved from a large veterinary database. Serum biochemical profiles from 3045 dogs were retrieved, of which 1495 had an accompanying normal glucose concentration. Sixty pure breeds plus a mixed breed control group were represented by at least 10 individuals. All analytes, except for sodium, chloride and glucose, showed variation with age. Total protein, globulin, potassium, chloride, creatinine, cholesterol, total bilirubin, ALT, CK, amylase, and lipase varied between sexes. Neutering status significantly impacted all analytes except albumin, sodium, calcium, urea, and glucose. Principal component analysis of serum biochemical data revealed 36 pure breeds with distinctive phenotypes. Furthermore, comparative analysis identified 23 breeds with significant differences from the mixed breed group in all biochemical analytes except urea and glucose. Eighteen breeds were identified by both principal component and comparative analysis. Tentative reference intervals were generated for breeds with a distinctive phenotype identified by comparative analysis and represented by at least 120 individuals. This is the first large-scale analysis of breed-specific serum biochemical phenotypes in the domestic dog and highlights potential genetic components of biochemical traits in this species. 相似文献

Two types of ateliotic dwarfism in 3 German Shepherd dog puppies are described. Low somatomedin levels in serum and impaired growth of skeletal tissues were found in all 3 cases. One dog (case 2) had a histologically undeveloped adenohypophysis, and the dwarfism was apparently due to a generalized lack of adenopituitary function. The 2 other dogs (cases 1A and IB) had histologically normal adenohypophyses, and their condition was probably due to a reduced response to endogenous growth hormone in peripheral tissues. 相似文献

Weaning and signs of a parent-offspring conflict were studied in four females of the Swedish Dachsbracken breed of domestic dog and their pups. The animals were observed from the second to the seventh week of age of the pups. In addition to regular weighing, measurements of milk and solid food intake per pup and meal were also made, and samples of milk from the mothers were collected and analysed. The most important mechanism for weaning seemed to be on the behavioural level. The time that the mother spent with her pups decreased continuously from week 2 to week 7, as did the number of sucklings per hour. Furthermore, both duration of suckling and the number of sucklings initiated by the mother decreased during the period, while the proportion of sucklings where the mother was standing increased steadily. The weights of mothers stayed rather constant during the period and there was no difference in the amount of milk given per suckling or in the composition of milk between the early and late weeks of lactation. Consequently, costs for the mother, in terms of loss of weight, were negligible as she was able to compensate for the increased energy demand of lactation with an increased food intake. There was a tendency for care-giving behaviour to decrease and aggression from the mother to increase at the same time as there was a tendency for care-seeking and contact-seeking behaviour from the pups to increase. These changes, together with the less frequent initiation of suckling by the mother, could perhaps be seen as signs of conflict. Conflict was defined according to TRIVERS' theory (1974) and referred to the disagreement between the female and her pups about the amount of care given. However, although the animals were kept in a way that allowed them to perform as much as possible of their natural behaviour, the good nutritional conditions, one of the characteristics of captive life, may have reduced overt parent-offspring conflict. 相似文献

In Sicily many tick borne diseases are endemic, in particular way those that see like main carrier ticks that prefer, for their vital cycle, climatic conditions characterized by high temperatures and a warmth-humid atmosphere. The more important pathologies transmitted by ticks causing diseases in dogs are babesiosis and ehrlichiosis. Borrelia burgdorferi, Anaplasma phagocytophilum, Rickettsia conorii, Coxiella burnetii and tick transmitted encephalitis virus assume particular relevance because they are agents of zoonosis. Our centre, C.R.A.Ba.R.T, have conducted many researches and carried out many tests for diagnostic aim in order to estimate the spread of the main tick borne diseases in Sicilians' dogs. A study lead on 342 dogs has evidenced seroprevalence for Babesia canis, Ehrlichia canis and Rickettsia respective of 5.17%, 21.70% and 53.43%. A study on zoonotic agent seroprevalences in dogs gave the following percentages: C. burnetii 31.50%, R. conorii 73.60% and A. phagocytophilum 32.80%. The data carried out from IZS Sicily diagnostic service on 5,634 tests done in 2004-2005, confirm the experimental results on the presence of B. canis, E. canis, R. conorii, A. phagocytophilum, C. burnetii, Rickettsia spp., Anaplasma spp. and Ehrlichia spp. in all the Sicilian areas. 相似文献
