| implications for thromboxane a2 in the pathogenesis of endotoxic shock. | during endotoxemia there is increased synthesis of arachidonic-acid-derived metabolites. we investigated the potential deleterious role of the proaggregatory vasoconstrictor, thromboxane a2, an arachidonic acid metabolite, in the endotoxic shocked rat. plasma levels of thromboxane b2, the stable metabolite of thromboxane a2, 6-keto-pgf1 alpha, the stable metabolite of pgi2, and pge were measured via radioimmunoassay. we also investigated the therapeutic efficacy of the fatty acid cyclo-oxygenase ... | 1981 | 6961767 |
| b cell tolerance: b cells rendered tolerant are present in the immune system in a potentially responsive form. | the mechanisms of b cell tolerance were studied in an attempt to learn whether b cells rendered tolerant are present in the immune system in a potentially responsive form. the author tested the in vitro anti-trinitrophenyl (tnp) antibody-forming cell (anti-tnp afc) response to tnp-immunogens and polyclonal b cell activators (pba) of spleen cells taken from mice injected with a tolerogen, tnp-carboxymethylcellulose (tnp-cmc). spleen cells from mice injected 5 days previously with 10 microgram of ... | 1980 | 6971390 |
| effect of endotoxin treatment on prostaglandin metabolism by rabbit uterus and oviduct. | metabolism of pge-2 and pgf-2 alpha by cytosolic fractions (100,000 g supernatant) of the uterus, oviduct and lung of rabbits treated with hcg and endotoxin (20 microgram/kg) was measured. endotoxin caused immediate decreases in metabolism of both pgs by uterus at 1 h, and these decreases became significant at 2 h for pge-2 and 6 h for pgf-2 alpha. the metabolism of both pgs remained depressed throughout the 24 h study. metabolism by oviduct tissue differed in that at 1 h metabolism of both pgs ... | 1980 | 6987394 |

| salmonella meningoencephalomyelitis in a northern fur seal (callorhinus ursinus). | salmonella enteritidis was isolated from the brain of a neonatal northern fur seal (callorhinus ursinus) with gross and microscopic lesions of meningoencephalomyelitis. microscopic lesions in the liver and lung suggested septicemia. | 1980 | 6990022 |
| adjuvant action of capsular polysaccharide of klebsiella pneumoniae on antibody response. viii. its effect on the size and the number of cells of regional lymph node and other lymphoid organs. | changes in the number of cells and the weight of various lymphoid organs of mice, such as the regional lymph node (right inguinal node), spleen, thymus, bone marrow, and peripheral blood, were followed after the subcutaneous injection of the capsular polysaccharide of klebsiella pneumoniae (cps-k). for comparison, the changes after injection of various polyclonal lymphocyte activators (pla) including various preparations of bacterial lipopolysaccharide (lps) were concurrently studied. the number ... | 1980 | 6991886 |
| ruptured mycotic aneurysm of a coronary artery. a fatal complication of salmonella infection. | a 53-year-old man with a kidney transplant was hospitalized because of back pain, fever, and an enlarging heart size. cultures of blood and stool yielded salmonella enteritidis (group d, serotype enteritidis). despite appropriate antibiotic therapy, the patient died of cardiac arrest on the seventh hospital day. autopsy revealed a ruptured mycotic aneurysm of the right coronary artery with hemopericardium. in addition, a ruptured aneurysm of the abdominal aorta was present. to our knowledge, rup ... | 1980 | 6994672 |
| mechanism of hyperinsulinemia in endotoxicosis. | hyperinsulinemia subsequent to endotoxemia is a key factor leading to the disturbance of glucose homeostasis in endotoxin shock. this study investigated the mechanism(s) of hyperinsulinemia during endotoxicosis in the rat. two primary mechanisms for the hyperinsulinemia were evaluted: 1) decreased removal of insulin by the endotoxic liver, and 2) increased secretion of insulin by the endotoxic pancreas. endotoxin treatment of donor rats did not impair the removal of tca-precipitable 125i-labeled ... | 1980 | 6996494 |
| unusual aspects of salmonella meningitis. | two cases of salmonella meningitis that demonstrate unusual clinical and epidemiologic features are reported. the first case was a two-month-old infant with relapsing salmonella meningitis in whom echo 2 virus and s. enteritidis grew in mixed culture from cerebrospinal fluid. the second case was a five-month-old with typhoid meningitis. although this patient eventually responded to chloramphenical, repeated csf cultures grew s. typhi despite his receiving high dose parenteral therapy with ampici ... | 1980 | 6996893 |
| [enteritis salmonellae in man and animal from 1953 to 1975 in southern bavaria (author's transl)]. | the present paper gives a survey of the enteritis salmonelloses in man during the years from 1953 to 1975 (19400 first isolations) and in animals in the period from 1965 to 1975 (4600 first isolations and identification) in southern bavaria. in southern bavaria the number of isolations from enteritis salmonellae in man and animal has strongly increased during the last few years and the same holds good for the number of serotypes (figs. 1, 2 and tables 1, 2). the most frequent serotypes in man ar ... | 1980 | 6998205 |
| experimental nephropathy induced in rabbits by immunization with escherichia coli 055 lipopolysaccharide. 2. immunologic findings. | thirty-seven rabbits were immunized against lipopolysaccharide from escherichia coli or salmonella enteritidis over a period of up to 16 months. the animals developed antibodies against rabbit renal glycoproteins and against bacterial polysaccharide; they also showed signs of kidney lesions. the immunoperoxidase test showed antibody and complement (c3) fixation on the periphery of glomeruli and tubules. antibodies extracted from the kidneys of the immunized animals reacted with isologous and aut ... | 1980 | 6998923 |
