inhomogeneous distribution of filipin-sterol complexes in the ciliary membrane of rat tracheal epithelium.	pieces of rat trachea fixed in a glutaraldehyde solution containing 300 mum filipin, a sterol-specific polyene antibiotic (elias et al., '78), were freeze-fractured in order to study the distribution of cholesterol within the ciliary membrane. filipin-sterol complexes, recognizable as 25-30-nm protrusions on fracture faces, appeared densely and uniformly distributed over most of the ciliary membrane, but were absent from the region of the ciliary necklace. it is possible, therefore, that the cil ...	1979	517447
histologic diagnosis of diseases of malabsorption.	the diagnoses which may be arrived at by examination of peroral small bowel mucosal biopsy specimens are presented. celiac sprue, unclassified sprue (refractory sprue), infectious gastroenterititis, stasis syndrome and kwashiorkor have a severe mucosal lesion. other clinical conditions are required to establish the diagnosis in these diseases. a number of diseases have specific diagnostic features. included are whipple's disease, abetalipoproteinemia, collagenous sprue, primary intestinal lympho ...	1979	517556

experimental granulomatous inflammation: ii. effect of injection of intact and disrupted killed tubercle bacilli into freund adjuvant-sensitized cavies.	the reaction of freund adjuvant-immunized cavies to subsequent injection of mycobacterium tuberculosis h37ra is confirmed as an immunologically mediated phenomenon. ultrasonic disruption of mycobacteria to be injected as "challenge" markedly increases the intensity of the consequent 24-48 h reaction and subsequent fibrosis in freund adjuvant-sensitized cavies and has an apparently inhibiting effect on the extent of subsequent granuloma formation with marked reduction of the density of epithelioi ...	1979	523183

insulin responsiveness of adipose tissue from normal weight subjects with early diabetes.	in normal weight subjects, classified by a 2-h glucose infusion test as having normal (11), borderline (3) or pathological (9) carbohydrate tolerance (cht), subcutaneous adipose tissue was removed under intracutaneous anesthesia by surgical biopsy. the biological responsiveness of isolated adipocytes as well as adipose tissue fragments measured as incorportion of (1-14c) glucose into co2 or triglycerides was studied in the absence or presence of different insulin concentrations. in persons with ...	1979	525210
serially etched shark enameloid observed by incident light microscopy.	longitudinal and transverse tooth sections of isurus oxyrinchus were serially etched in 2.6% nitric acid. the changing optical properties of the etched surfaces were observed during the serial etchings, and the descent of the enameloid surfaces was measured. shark enameloid seems to be less effectively etched by acid than human enamel; this difference may be due to differences in solubility between fluorapatite and hydroxyapatite. most of the information regarding the structure of the enameloid ...	1979	525241
hybridization and heat tolerance in rats.	buffalo and fisher inbred rats and their f1--f4 hybrids were exposed to heat, 96 degrees f and 30% humidity, at 35 days of age. fisher rats which are of lighter weight survive significantly longer than buffalo rats which are heavier. body weight was significantly depressed in all hybrids. only in f2 hybrids was heat tolerance similar to that of the fisher inbreds. in all other hybrids, it was lower. no heterosis was found under the conditions used.	1979	525249

the effect of temporary exercising of a joint during an immobilization period: an experimental study on rabbits.	the right hind limbs of adult rabbits were immobilized for 5 weeks. the rabbits were then allowed to move freely for 8 weeks. the rabbits of the control group were immobilized uninterruptedly. in a second group of rabbits the plaster was removed during the immobilization period 6 days a week for 5 minutes for careful exercise and in a third group of rabbits, for violent exercise. the temporary careful exercise was of no benefit and was sometimes harmful, and the violent exercise was usually inju ...	1979	535243
euthanasia: a serene voyage to death?	modern western culture regards death as a threatening enemy, whereas the ancients, as is the case in eastern philosophy, recognized both the fight with, and the releasing surrender to death. dying is quite often a serene voyage, be it through old age, sickness, was or even suicide. attentive listening to those who face the termination of incurable disease reveals the voice of enlightenment: 'euthanasia' also means 'clarified dying'. an attitude like this alleviates our recoil and assists in a su ...	1979	535362

plasmids in yersinia pestis.	pesticinogenic and ca2+-dependent strains of yersinia pestis harbored plasmids of about 6 and 45 megadaltons, respectively. in addition, most isolates examined possessed a cryptic 65-megadalton plasmid.	1981	7216478
occurrence of yersinia enterocolitica in wild animals.	yersinia species were isolated from 16 of 495 small wild animals and from 1 of 38 foxes. the animals were trapped in seven regions of hokkaido, japan. of the 17 strains isolated, 9 were yersinia enterocolitica o6; 2 were y. enterocolitica o5a; 1 was y. enterocolitica, o4; 1 was y. enterocolitica o9; 1 was yersinia pseudotuberculosis ivb; and 3 were sucrose-negative strains. yersinia pestis was not isolated. the o6 organism was most prevalent in large red-back mice (clethrionomys rufocanus bedfor ...	1981	7224628
plague in a neonate.	more than half of the cases of plague in the united states are diagnosed in children. in the 1970s, 105 cases were reported, a 350% increase over the 1960s. plague should be considered in the differential diagnosis of children from the western united states who have sepsis, especially those with lymphadenopathy. complications of plague include meningitis, metabolic encephalopathy, abscess, and pneumonia. with appropriate treatment, prompt clinical response usually occurs. careful isolation and e ...	1981	7234765
[utilization and fermentation of 2-ketogluconate by "enterobacteriaceae" (author's transl)].	two methods were compared: 1) the ability to use 2-ketogluconate (2-kg) as source of carbon and energy in defined medium, and 2) the ability to produce acid by fermentation of 2-kg (0.5 g/100 ml) in peptone water with phenol red. results of growth on, and acid production from, 2-kg were identical. a total of 990 strains was studied. no strain of escherichia coli, shigella (4 species), salmonella (4 sub-genera), yersinia pestis, y. pseudotuberculosis, edwardsiella (2 species), proteus vulgaris, p ...	1981	7235456
