Studies of cardiac pathomorphology in swine which died during transport     

U Johannsen 《Archiv fuer experimentelle veterinaermedizin》1979,33(3):377-391

The following findings were obtained from pathomorphological examination of the myocardium of 100 pigs which had died on transport: Degenerative or necrobiotic changes of certain myocardial fibres were recorded from 73 per cent of all cases, usually in the form of granular degeneration (60 per cent). They were "scattered" in 33 per cent of all cases, "multiple" in 22 per cent, and "frequent" in five per cent. In 26 per cent, the myocardial fibres had undergone coarse granular or hyalin plaque-type decomposition, among them with "scattered" manifestation in 15 per cent, "multiple" in four per cent, "frequent" in five per cent, and "massive" in two per cent. Moderate focal resorptive myositis was recorded from eight per cent, while earlier myocardial scars were exhibited by four per cent. The figure for reactive inflammatory processes was twelve per cent. Prestatic hyperaemia of different degrees had taken place in 75 per cent of all animals, and it had been accompanied by varied congestion. The following results were obtained from comparative checks of 100 hearts of clinically intact pigs after slaughter under normal conditions: Granular degeneration was recorded only from 18 per cent of all cases, with actual manifestations "scattered" in 16 per cent and "multiple" in two per cent. Their myocardial fibres had undergone coarse granular or hyalin plaque-type decomposition of moderate intensity in three per cent only, all of them having been "scattered". Reactive inflammatory changes were not recorded at all and signs of prestatic hyperaemia only in 46 per cent. The degenerative-necrobiotic alterations of myocardial fibres which had been observed in the context of death on transport are interpreted as a result of hypoxaemic or hypoxic conditions accompanying acute shock-type circulatory failure in pigs.  相似文献   

Enzyme arrangement of various tissues in swine. 1. Studies of the effect of 32 hours of fasting, administration of actinomycin D, and fasting in combination with administration of actinomycin D on crude protein level, activities of GOT, GTP, fructose-1,6-diphoaphatase as well as ATPase of liver, kidneys and semitendinous muscle in newborn piglets]

The effects of sufficient milk intake as well as of 32 hours of fasting after birth, administration of actinomycin D (intraperitoneal application of 1 mg/kg five weight), and fasting in combination with actinomycin D on the development of body and liver weights, crude protein levels in homogenate and supernatant of liver, kidneys, and M. semitendinosus as well as on the activities of certain tissue enzymes were analysed with four groups of piglets (n = 4). Fasting, administration of actinomycin, and fasting in combination with actinomycin D resulted in rapid reduction in body and liver weights, while the crude protein levels in those tissues were not affected with significance. GOT and fructose-1,6-diphosphatase activities in supernatant from liver tended to decline under fasting conditions. The ATPase activity in the homogenate of the above tissues did not change in response to differentiated treatment.  相似文献

Intussusception following renal transplantation in dogs (author's transl)]     

P R Olsen  F Boserup  A M Mikkelsen  U Rorbech 《Nordisk veterinaermedicin》1977,29(1):36-40

In a consecutive and non-selected study of 54 kidney transplanted dogs, 12 cases of intussusception of the small intestine developed in 8 dogs. The patogenesis is still unknown. It has been postulated that the time of the operation (4--7 hours) and the segmental termination of the post-operative atony in the intestine are essential factors in this fatal complication. The last 16 dogs in this material were peroperatively treated with antikolinergics (Mestinon NFN), which was continued until normal function of the intestine. In these dogs there were no evidence of intussusception. The value of this profylaxis is open to discussion and it is essential to solve the problem of intussusception through a "blind" and controlled trial.  相似文献   

The use of the sugar beet in swine nutrition. 2. The effect of different preparation processes on the apparent prececal and fecal digestibility     

U Kesting  H J Block  G Bolduan 《Archives of Animal Nutrition》1990,40(10):943-949

With ileum cannulated sows were tested the apparent precaecal and faecal digestibility of crude nutrients from raw and thermically treated fodder sugar beets of size "Rosamona". Two samples from two different harvest years, differing extremely in the content of disaccharides were tested. The crude nutrient digestibility affected stronger by content of sucrose then by treatment. Fodder sugar beets with contents of disaccharide lower then 400 g/kg DM showed low precaecal and faecal digestibilities. A longer cooling phase decreased the feed value of steamed beets through the microbial attack in the formation of precaecal indigestible sugar alcohols (mannitol).  相似文献   

Contribution to the morphology and biochemistry of mustelide blood. 1. Blood specimen collection in various mustelides with special reference to the use of the tissue adhesive "Fimomed"]     

R Zeissler  U D Wenzel 《Archiv fuer experimentelle veterinaermedizin》1978,32(5):727-736

An account is given of various techniques of blood sampling in the context of certain mustelids, including cardiopuncture, amputation of tail tip, talon cutting, incision of the ear vein, puncture of the jugular or femoral vein, and catheterisation of the abdominal aorta. Reference is made to details of use of all techniques, characteristics, advantages and potential setbacks, and preferable use of some of the tested methods to collect blood from mustela and martes species. Blood collection from the abdominal aorta may be helpful in obtaining no-haemolysis and no-additive plasma for biochemical multi-screening. Biochemical, pharmacological, and toxicological follow-up checks may be feasible under certain conditions following surgical exposure of the external jugular vein. The use of "Fimomed" (n-butylcyano-acrylate), a tissue adhesive, may help to reduce effort in terms of time and material and consequently, rationalise veterinary hygiene action as a whole, provided that the conditions for its application are observed. The skin adhesive is properly applicable to skin lesions of mustelids. A combination of suturing with adhesive should be used to close laparotomy wounds for better mechanical strength of the abdominal wall. Possible applications of "Fimomed" should be tested with other species as well.  相似文献

Impact of environmental factors on infestation of tea leaves byHelopeltis theivora, and associated changes in flavonoid flavor components and enzyme activities     

U. Chakraborty  N. Chakraborty 《Phytoparasitica》2005,33(1):88-96

Attack of tea plant (Camellia sinensis (L.) O. Kuntze) leaves by the tea mosquito bugHelopeltis theivora (Hemiptera: Miridae) was positively correlated to temperature and rainfall, and partially to humidity, as determined in 12 varieties during the period 2000–2002. The insect attack was severe during the months of May–September, which had high temperature and rainfall, and led to severe loss of biomass due to curling and drying up of the leaves. The biochemical response of these 12 varieties of tea to attack by the insect was determined with special reference to oxidative enzymes and flavonoid flavor components. Insect attack led to an increase in the activities of the oxidative enzymes peroxidase, ascorbate peroxidase and polyphenol oxidase. Activities of phenyl alanine ammonia lyase generally decreased as a result of insect attack, which was significant in the United Planters Association of South India (UPASI) varieties. A significant decrease in polyphenols was also obtained in UPASI varieties. HPLC analysis of catechins revealed a decrease in some of the catechins in the infected leaves. Analysis of theaflavins from infusion of healthy andHelopeltis-infested tea leaves revealed no changes. http://www.phytoparasitica.org posting Dec. 19, 2004.  相似文献
