| the possibility of detecting fetal lymphocytes in the maternal blood of the domestic pig, sus scrofa. | fourteen pregnant sows were examined to determine if transplacental migration of fetal lymphocytes had occurred. giemsa-stained and c-banded karyotypes were examined. male metaphases constituted 1% to 4% of all metaphases of peripheral blood leukocytes of pregnant sows. regardless of the experimental method or stage of gestation, no essential differences were found in the number of male cells. | 1983 | 6641289 |
| [mathematic approximations of mass growth in pig fetuses and comparison with homo sapiens]. | values for fetal mass growth over unequal time intervals of pregnancy as given by brune (1972) for the domestic pig are submitted to nonlinear regressions in order to achieve mathematical approximations. altogether 7 functions of organic growth are considered in their unbound form, as fetal mass growth is extremely slow in the 1st quarter of gravidity thus outruling the necessity of introducing an exact initial value. in contrast to many other investigations into organic growth all functions yie ... | 1983 | 6653997 |
| partial ablation of the kidney by intraarterial ethanol in domestic swine. | partial renal ablation was produced in 15/17 swine kidneys after segmental intraarterial injection of 1-2 ml of 95% ethanol. complications were seen in 3 kidneys, including reflux of ethanol into nontarget vessels with subsequent total infarction of 2 kidneys, and the development of hydronephrosis in 1 kidney. strictly selective catheterization and a very slow injection of ethanol are essential to avoid complications. this technique may find clinical application and the possible indications are ... | 1983 | 6659203 |

| genome size of man and animals relative to the plant allium cepa. | a direct feulgen-cytophotometric comparison of the genomic dna content (c value) was performed between the liliaceous plant species allium cepa and a number of animal species to reassess the genome size ratios between plants and animals. these appeared unduly ambiguous as a consequence of divergent picogram estimates in several animal reference species. taking 1c = 16.75 pg for allium cepa, the estimates were (1c value in picograms): man, 3.11; indian muntjak ccl 157 cell line, 2.68; domestic pi ... | 1983 | 6671147 |
| blood coagulation studies in domestic pigs (hanover breed) and minipigs (goettingen breed). | blood coagulation studies were performed on 60 hanover domestic pigs ready for slaughter and a total of 84 goettingen minipigs. a tendency to hypercoagulability was found in these pigs, expressed in a shortened ptt, r- and k-time in the thromboelastogram and a slightly reduced plasminogen and plasmin level. many values were similar to those of man. thrombin time was longer. this may be due more to enhanced formation of fibrin degradation products (anti-thrombin vi) than to greater amounts of end ... | 1983 | 6678359 |
| [quantitative characteristics of the nucleolus organizer region of the chromosomes in the domestic pig]. | absolute and relative dimensions of ag+-nors and secondary constrictions (sc) of pig chromosomes were determined. interchromosomal and interindividual variability of these indices were marked. an attempt was undertaken to standardize the absolute sizes of ag+-nors and sc, degrees of chromosome condensation being taken into consideration. a high correlation between the dimensions of ag+-nor and of sc was noted. | 1984 | 6701970 |
| effect of platelet-activating factor on coronary circulation of the domestic pig. | the platelet-activating factor released by white blood cells and platelets has been shown to be 1-o-hexadecyl-2-acetyl-sn-glycero-3-phosphocholine (agepc). to fully understand the cardiovascular actions of this substance, we examined the effects of agepc on coronary blood flow (cbf) and other hemodynamic parameters in anesthetized open-chest domestic pigs. mean arterial blood pressure (mbp), electrocardiogram, heart rate (hr), left ventricular pressure, and cbf were continuously recorded. agepc ... | 1984 | 6703081 |
| contrasting effects of nifedipine and adenosine on regional myocardial flow distribution and metabolism distal to a severe coronary arterial stenosis: observations in sedated, closed-chest, domestic swine. | this study tested the hypothesis that intrinsic negative inotropic effects of a drug used to induce coronary vasodilation distal to a severe coronary arterial stenosis may influence the extent of redistribution of transmural flow and its metabolic consequences. to test this hypothesis, studies were conducted in eight closed-chest, sedated swine with severe (82% reduction in luminal diameter) coronary arterial stenoses. measurement of hemodynamic parameters, regional myocardial blood flow (micros ... | 1984 | 6705159 |
| nor activity, heterochromatin differentiation, and the robertsonian polymorphism in sus scrofa l. | the karyotype of the european wild pig (sus scrofa scrofa l.) was analysed by means of silver-staining and the chromomycin a3/distamycin a/dapi fluorescent banding technique to locate active nors and to differentiate types of c-bands. the ribosomal rna genes are localized at the secondary constrictions of chromosomes 8 and 10. all biarmed chromosomes, with the exception of chromosome 15/17 and the y, had a chromomycin bright centromeric region that was moderately fluorescent with distamycin a/da ... | 1984 | 6707448 |
| influence of adenosine on basal myocardial function: observations in anaesthetised, domestic swine. | data from experiments in isolated cardiac muscle preparations indicate that adenosine in high concentration (10(-3) mol x litre-1) exerts a negative inotropic effect on the myocardium under basal conditions. the following study was performed to test the hypothesis that adenosine exerts a similar negative inotropic effect when administered in an intact animal model in a dose sufficient to cause maximal coronary vasodilatation. six open chest anaesthetised pigs were studied as follows. ultrasonic ... | 1984 | 6713450 |
| [pre- and perinatal oxygen transport in mammals: the embryonic hemoglobins of the domestic pig (sus scrofa domestica)]. | pigs express two globin genes of beta-type, the epsilon- and chains during their embryonic stage. with the alpha- and epsilon-chains they form four embryonic hemoglobins. we describe here in detail the experimental procedures for sequencing the epsilon- and chains from the pig (sus scrofa domestica) and we discuss the data with respect to their special functional properties. from the components gower i and heide i, we obtained all embryonic chains by chromatography on cm-cellulose. the sequence ... | 1984 | 6724525 |

| effects of low energy laser on wound healing in a porcine model. | low energy helium neon laser has been suggested as an effective adjuvant in the healing of open wounds. to date, supportive studies have been performed in loose-skinned animals. for such data to be clinically meaningful, it was felt necessary to study this effect in an animal with a dermal structure more closely resembling that of man, the pig. after creating 62 partial thickness wounds on the dorsum of domestic swine, one-half of these were randomized to receive laser treatment. the remainder s ... | 1984 | 6727528 |
| trichinella isolates from polar bears in svalbard. freeze resistance and infectivity in rats and swine. | the author isolated trichinella strains from five polar bears in svalbard (the high arctic region of norway). based on infectivity experiments with white mice (bom:nmr), the freeze resistance limits of the trichinella strains are outlined. further experiments showed that white rats (mol:wist) and pigs (sus scrofa domestica) are almost refractory to these trichinella strains. the infectivity of svalbard isolates in the above mentioned test animals was compared, in parallel experiments, with that ... | 1984 | 6728674 |
| experimental infection of domestic swine with baylisascaris procyonis from raccoons. | six 8-week-old ascarid-naive pigs which were experimentally infected with 72,000 embryonated baylisascaris procyonis eggs of raccoon origin developed lesions limited to the intestines and liver. intestinal lesions consisted of multifocal areas of inflammation by macrophages, eosinophils, and lymphocytes in the mucosa and submucosa, in association with baylisascaris larvae; similar lesions were seen in the mesenteric lymph nodes. typical white, granulation type, multifocal interstitial hepatitis ... | 1984 | 6742572 |
