an updated survey of african swine fever in malawi.cases of african swine fever (asf) confirmed in the laboratory in 1985 and 1986 and other data obtained since 1984, in particular and extension of the serological survey of free-ranging domestic pigs undertaken from 1981 to 1984, are presented to give an updated survey of the asf situation in malawi and a revised estimate of the asf enzootic area. evidence is presented that the area may include some border areas in dedza and ntcheu districts and may be expanding in some localities.19873322852
[arterial vessels of the kidney in domestic swine].by histological preparation, measuring, corrosion and angiography were studied the arterial blood vessels of 120 kidneys from 60 individuals at different ages. it was established that the kidney artery in the most cases (70%) divides by the dichotomous type in cranial and caudal or in dorsal and ventral branches, and rarely (30%) by the disseminated type in 3 branches--two cranial and one caudal. investigated were the position, course and branching of the prelobar, interlobar, the arcuate, the i ...19873328404
an animal model for radiologic biliary interventional procedures.procedural development, in vivo evaluation, and professional training in interventional biliary radiology require an animal model that provides easy and safe access to the gallbladder and bile ducts. a porcine model was used successfully for catheterization of the biliary system under fluoroscopic control. permanent access to the gallbladder of ten pigs was achieved with a large-bore cholecystostomy catheter. catheterization of the common bile duct through the cystic duct was feasible in all ani ...19883338897
influence of serotonin on myocardial blood flow in the presence and absence of a coronary arterial stenosis: observations in domestic swine.this study tested the hypothesis that 5-ht may impair coronary flow regulation by inappropriately increasing arteriolar tone in the coronary circulation. ten closed chest, domestic swine were studied both in the presence and in the absence of a severe artificial intraluminal coronary stenosis. a 5-french micromanometer catheter with fluid lumen was placed in the left anterior descending coronary artery and used to record pressure and infuse 5-ht (40 and 100 micrograms/min) into the coronary circ ...19883353390
effect of pressure-controlled intermittent coronary sinus occlusion on pacing-induced myocardial ischemia in domestic swine.this study tested the hypothesis that pressure-controlled intermittent coronary sinus occlusion (picso) would be useful in ameliorating myocardial ischemia under conditions characterized by preserved, but reduced (relative to demand), myocardial blood flow. studies were conducted in closed-chest, sedated domestic swine prepared with an artificial stenosis that reduced luminal diameter of the animal's left anterior descending coronary artery by 80%. measurements of hemodynamics, regional myocardi ...19883370777
periodontal disease in feral pigs (sus scrofa) from queensland, australia.periodontal lesions were present in 26 of 107 feral pigs (sus scrofa) that were shot in southern queensland. the severity of the lesions varied from gingivitis to extensive destruction of the alveolus and its contents. examination of slaughtered domestic pigs revealed a similar prevalence of lesions (12 of 52). only cheek teeth were affected, and molars were affected more frequently than premolars. in both feral and domestic pigs, prevalence of periodontal disease affecting bone increased with a ...19883373625
comparative anatomy of the foramen ovale in the suina.the structure of the foramen ovale from six species of suina was studied using the scanning electron microscope. in each species, the foramen ovale, when viewed from the terminal part of the caudal vena cava had the appearance of a short tunnel. in the domestic pig (sus scrofa), the wart hog (phacochoerus aethiopicus) and the bush pig (potamochoerus porcus) a fold of tissue projected from the caudal edge of the foramen ovale into the lumen of the left atrium. it constituted a large proportion of ...19883377202
fatigue of three skeletal muscles in domestic and wild pigs. a comparative study in situ.the semitendinosus, the gastrocnemius and the soleus muscle were stimulated in situ in young, female domestic pigs (sus scrofa domestica, german landrace) and in european wild pigs (sus scrofa scrofa), by supramaximal impulses via the sciatic nerve. fatigue indices of the whole muscles were registered during a continuous supramaximal stimulation with square wave impulses (0.3 ms) that were given for 10 s with a frequency of 100 hz. in domestic pigs, fatigue indices of all three muscles were sign ...19883399363
isolation of african swine fever virus from ticks of the ornithodoros moubata complex (ixodoidea: argasidae) collected within the african swine fever enzootic area of malawi.ticks of the ornithodoros moubata complex were collected from domestic pig sties and dwelling houses, and from a warthog habitat, and tested for the presence of african swine fever (asf) virus. collections were made in 9 of the 24 districts of malawi, these being primarily the districts in which o. moubata is most numerous. asf virus was isolated from ticks collected in both domestic pig sties and houses in certain villages in mchinji district where asf outbreaks had recently occurred. mchinji d ...19883402546
metabolic response to prolonged reduction of myocardial blood flow distal to a severe coronary artery stenosis.limited data are available concerning the effects of mild-to-moderate, sustained reductions of coronary blood flow on myocardial aerobic metabolism. this study tested the hypothesis that a sustained flow reduction distal to a severe coronary artery stenosis may be well tolerated (after the initial insult is passed) because of gradual improvement in the balance between myocardial oxygen supply and demand. studies were performed in eight sedated, closed-chest domestic swine that were instrumented ...19883409507
cardiovascular effects of i653 in swine.i653 (difluoromethyl 1-fluoro 2,2,2-trifluoroethyl ether) is a new inhalation anesthetic with a low blood-gas partition coefficient and no demonstrable toxicity. the authors examined its cardiovascular effects at 0.8, 1.2, and 1.6 mac in eight chronically instrumented domestic swine mechanically ventilated to maintain normocarbia. these data were compared with those obtained while the animals were conscious and while anesthetized with isoflurane at approximately equal mac multiples. i653 caused ...19883415011
intratubular germ cell tumours of pig testicles.in the course for the histopathological examination of testicles of 30 castrated boars the authors have observed in 4 animals the intratubular growth of atypical germ cells. on the basis of the histological picture this change is equivalent to the human infertile testicles, observed as carcinoma in situ, resp. intratubular germ cell tumour. the described phenomenon occurred in atrophic testicles in 3 of the 4 old animals. the described change in the domestic pig, not known so far, raises the pos ...19873425959
