| three-dimensional 87rb imaging of isolated pig hearts: effects of regional ischemia. | the aim of this work was to investigate whether 1) rb uptake is reduced in ischemic myocardium, and 2) 87rb three-dimensional (3d) imaging can detect the ischemic area. hearts of domestic pigs (n = 8, 20-30 kg) were perfused retrogradely with krebs-henseleit buffer in a 7-t, 40-cm horizontal bore magnet interfaced with bruker mslx spectrometer. control (c) and ischemic (i) (45 min ligation of the left anterior descending coronary artery (lad)) hearts were loaded with rb+ by perfusion with a rb(+ ... | 1998 | 9702698 |
| technetium-99m-nitroimadazole uptake in a swine model of demand ischemia. | nitroheterocycles are electron affinic, lipophilic compounds that are retained in hypoxic tissue. this study was designed to test the hypothesis that 99mtc-5-oxa-amine-oxime nitroimadazole (bms-194796) is retained in ischemic myocardial tissue in a swine model of demand ischemia and that the retained tracer can be imaged in vivo. | 1998 | 9708532 |
| flap flow and cardiac output as functions of pulmonary artery wedge pressure: experimental study in the pig. | cardiac output (co) is redistributed during hypovolemia, but it has not been clearly documented how this influences flap perfusion. simultaneous changes in perfusion of a muscle flap and co as modulated by reductions in cardiac filling pressure were compared in a pig model. the hypothesis was that flap flow (ff) would remain relatively constant as co was reduced, according to the frank-starling curve. under general anesthesia, five domestic pigs were utilized. following right carotid artery cann ... | 1998 | 9714037 |
| midazolam-fentanyl-isoflurane anaesthesia is suitable for haemodynamic and fluid balance studies in pigs. | the domestic pig is a useful model in certain areas of biomedical research. effective use of this species is often encumbered by lack of reference values in conscious as well as anaesthetized animals. anaesthesia itself influences physiological and biological variables; the anaesthetic technique often affects experimental results. the relationship between anaesthesia and haemodynamics is well characterized in man, but less established in pigs. we studied the effect of midazolam-fentanyl-isoflura ... | 1998 | 9718480 |
| molecular basis for the dominant white phenotype in the domestic pig. | the change of phenotypic traits in domestic animals and crops as a response to selective breeding mimics the much slower evolutionary change in natural populations. here, we describe that the dominant white phenotype in domestic pigs is caused by two mutations in the kit gene encoding the mast/stem cell growth factor receptor (mgf), one gene duplication associated with a partially dominant phenotype and a splice mutation in one of the copies leading to the fully dominant allele. the splice mutat ... | 1998 | 9724328 |
| serological and immunohistochemical study of african swine fever in wild boar in spain. | a serological and immunohistochemical study of african swine fever was carried out in wild boar killed in seven municipalities in the north of the province of córdoba during two hunting seasons (1991-92 and 1992-93), when the area was affected by the disease. fourteen of 147 wild boar analysed by elisa and immunoblotting had antibodies to african swine fever virus. the immunohistochemical study revealed that four cases (two seropositive and two seronegative) showed immunoreactivity to the anti-v ... | 1998 | 9725185 |
| pulmonary function after one-lung ventilation in newborns: the basis for neonatal thoracoscopy. | to maintain good exposure during major video-assisted thoracic surgery it is necessary to deflate completely the ipsilateral lung. however, little is known about the effects of one-lung ventilation (olv) on pulmonary function in newborn patients. | 1998 | 9725400 |
| measurement of adenosine concentration in aqueous and vitreous. | the release of adenosine by the ischemic retina may be an initial signal in the development of ischemic macular edema and neovascularization. the levels of adenosine have never been quantified in ocular fluids. in this study, a technique was developed for in vivo measurement of the concentration of adenosine in aqueous and vitreous. | 1998 | 9727417 |
| experimental tricyclic antidepressant toxicity: a randomized, controlled comparison of hypertonic saline solution, sodium bicarbonate, and hyperventilation. | we sought to compare the effects of hypertonic sodium chloride solution (hts), sodium bicarbonate solution, and hyperventilation (hv) on severe tricyclic antidepressant (tca) toxicity in a swine model. | 1998 | 9737495 |
| morphologic peculiarities of the renal cortical vasculature connected with blood redistribution in the kidney of the domestic pig. | the cortical blood vessels from 2 to 8 month old camborow hybrid pigs and belgium landrace pigs were studied using histologic and semithin sections as well as corrosion casts and cleared preparations of intravascular injection. it was established that the cortical blood vessels of the porcine kidney possess peculiarities that may regulate the redistribution of blood in the cortex. these peculiarities were found in the interlobular arteries, in the efferent arterioles of midcortical nephrons, in ... | 1998 | 9741149 |
| effects of weaning and restraint stress on glucocorticoid receptor binding capacity in limbic areas of domestic pigs. | changes in glucocorticoid receptor (gr) binding in different brain areas were investigated in neonatal and adult pigs exposed to psychological stress (weaning) and a physical stressor (repeated snaring). the gr binding was significantly decreased 4 days after weaning in both the hippocampus and the amygdala, but there were no changes in the hypothalamus. repeated snaring of adult pigs resulted in a significant diminished gr binding only in the hippocampus. | 1998 | 9757073 |
| five new cases of reciprocal translocation in the domestic pig. | five new cases of reciprocal translocation in the domestic pig are described. three of them, rep(3;5)(p1.3;q2.3), rep(6;13)(p1.5;q4.1) and rep(13;17)(q4.1;q1.1) were found in boars with decreased litter size. the remaining two were identified in animals karyotyped before reproduction: a young boar, rep(4;6)(q2.1;q2.8), and a gilt, rep(2;14)(q1.3;q2.7). a parental origin by inheritance of the translocations was established in cases 1, 4, and 5. a decrease in prolificacy of 43% and 34% was estimat ... | 1998 | 9760870 |
| the toxic mechanism and metabolic effects of atractyloside in precision-cut pig kidney and liver slices. | the toxic and cellular metabolic effects of atractyloside, a diterpenoid glycoside, which causes fatal renal and hepatic necrosis in vivo in animals and humans, have been investigated in tissue slices prepared from male domestic pig kidney and liver. precision-cut slices (200 microm thick) were incubated with atractyloside at concentrations of 200 microm, 500 microm, 1.0 mm and 2.0 mm for 3 h at 37 degrees c and changes in lipid profile and pyruvate-stimulated gluconeogenesis investigated. lipid ... | 1998 | 9765068 |
| left ventricular functional improvement after transmyocardial laser revascularization. | transmyocardial laser revascularization has been used to treat patients with end-stage coronary artery disease that is not amenable to standard revascularization. although there is evidence of angina relief and quality of life enhancement, there is little information concerning improvement in myocardial contractility. the purpose of this study was to determine whether transmyocardial laser revascularization improves myocardial function in chronically ischemic myocardium. | 1998 | 9768921 |
| diving seals, ischemia-reperfusion and oxygen radicals. | the cardiovascular adaptations of seals that contribute to their ability to tolerate long periods of diving asphyxial hypoxia result in episodic regional ischemia during diving and abrupt reperfusion upon termination of the dive. these conditions might be expected to result in production of oxygen-derived free radicals and other forms of highly reactive oxygen species. seal organs vary during dives with respect to the degree and persistence of ischemia. myocardial perfusion is reduced and interm ... | 1998 | 9773490 |
| angiographic and histological evaluation of porcine retinal vascular damage and protection with perfluorocarbons after massive air embolism. | we have previously shown that perfluorocarbon emulsions (pfes) reduce the severity of cerebral injury (indicated by infarct, reduced blood flow, and depressed eeg) induced by air embolism during cardiopulmonary bypass (cpb). this study used retinal fluorescein angiography to define the mechanisms of cerebral injury and to determine the efficacy of pfes in cerebral protection. these angiographic findings were correlated to previously reported histologic findings. | 1998 | 9804654 |
| genetic and experimental evidence for cross-species infection by swine hepatitis e virus. | prior to the recent discovery of the swine hepatitis e virus (swine hev) in pigs from the midwestern united states, hev was not considered endemic to this country. since swine hev is antigenically and genetically related to human strains of hev, it was important to characterize this new virus further. the infectivity titer of a pool of swine hev in pigs was determined in order to prepare a standardized reagent and to evaluate the dose response in pigs. although the sequence of swine hev varied e ... | 1998 | 9811705 |
