the general practitioner and the endodontist.one of the rewards of specialty practice is the opportunity to work with a great many referring dentists. the camaraderie is good, the friendships that develop are satisfying and long lasting. the specialist's goals are the same as those of the general practitioner: to provide the highest level of care possible in the best interest of their shared patient. this is best accomplished by open and effective communication between the general practitioner, the endodontist, and their mutual patient.1980294398

cellular immune response to yersinia pestis modulated by product(s) from thymus-derived lymphocytes.resistance to infection with yersinia pestis was found to depend on whether the macrophage can inactivate and withstand the cytotoxic effects of phagocytized y. pestis. serum from mice immunized with antigens of y. pestis enhanced the resistance of monolayers of normal cultures to the cytotoxic effects of y. pestis and increased the capacity of peritoneal exudate cells from immune mice to inactivate these bacteria. the enhancing component of the serum was not removed by absorption with heat-kill ...1977299867
structure and barr body formation of an xp + chromosome with two inactivation centers.a patients with seizures, von willebrand disease, and symptoms of turner syndrome was a chromosomal mosaic. in blood culture (1974), 56% of the cells were 45, x 33% 46, xxp+ and 11% 47,xxp + xp +; in the skin, no cells with 47 chromosomes were found. presumably the xp + chromosome arose through a break in the q-banded dark region next to the centromere on xp to which an xq had been attached. the abnormal x was late-labeling and formed a larger than normal barr body. of the chromatin-positive fib ...2003299980

the serological response to yersinia pestis infection.passive haemagglutination antibody titres to fraction i antigen of yersinia pestis were plotted against day of clinical illness in 82 patients in viet nam. a rise was evident by day 5 with a peak at day 14, after which a plateau occurred. in contrast to all other patients, 2 patients with recurrent infections had elevated titres at the time of admission which decreased significantly during convalescence.1977302154
[ring of the chromosome 4. ii. without facial dysmorphism].a r(4) was observed in a 5-year-old female patient, with growth retardation, a near normal psychomotor development and with no major dysmorphism. the break points were in p16 and q33. after comparison with other known observations of r(4) it is suggested that the phenotype of monosomy 4p is due to monosomy for the distal band 4p16.1977302682
partial tetrasomy 9(9pter to 9q2101) due to an extra iso-dicentric chromosome.a 3-year-old boy with partial no. 9 tetrasomy is described. the patient showed markedly retarded physical and mental development as well as multiple congenital anomalies. routine chromosome analysis revealed an extra c-group chromosome. it had a pronounced secondary constriction at the proximal part of its long arm. based on studies by a variety of banding techniques, the extra chromosome was identified to be an iso-dicentric no. 9 chromosome with inactivation of one of the two centromeres, the ...1977302683
mosaic 45,xy,-21/46,xy in a child with g deletion syndrome i.a mosaic 45,xy,-21/46,xy was found in a boy with g deletion syndrome i who showed microcephaly, downward, antimongoloid slanted eyes, micrognathism, large, low set ears, small penis and bilateral inguinoscrotal hernia.1977302684
erythrocyte autoantibodies induced in mice immunized with rat antigens.antibody reacting against syngeneic mouse erythrocytes could not be elicited (by rat erythrocytes) in athymic nude mice. rat antigen preparations from heart, muscle testes, brain erythrocyte ghosts and foetal material failed to elicit detectable autoantibody reactivity against mouse erythrocytes, even though all these preparations (other than brain and foetal) induced a reduction in half life of syngeneic murine erythrocytes in vivo. we suggest that an unstable rat erythrocyte antigen is respons ...1977303095
b- and t-cells and ig-containing blast cells in healthy children.studies on rosette-forming cells and igg, iga, igm and ige-bearing lymphocytes were carried out in 70 healthy children aged 5 to 15 years. furthermore, in 20 of these children, the percentages of igg, iga, igm and ige-containing blast cells after pokeweed mitogen stimulation of peripheral lymphocytes were evaluated. no differences in the percentages of rosette-forming cells, or in ig-bearing and ig-containing cells were found when three different age-groups were compared.2004303435

partial duplication 5q syndrome: phenotypic similarity in two sisters with identical karyotype (partial duplication 5q33 leads to 5qter and partial deficiency 8p23 leads to pter).two sisters with statomotor developmental retardation microcephaly, hydrocephalus internus and externus without signs of pressure, heart defect (ventricular septal defect), early pulmonary resistance and characteristic facial changes were found to have the same unbalanced karyotype with partial trisomy 5q3300 leads to 5qter and partial monosomy 8p2300 leads to 8pter, derived from a balanced reciprocal paternal translocation: 46,xy,t(5;8)(q3300;p2300). the older girl was tested for the erythrocyt ...1977305758
technical considerations in saphenous vein bypass grafts to the right coronary artery.measurement of the proper length for saphenous vein bypass grafts to the right coronary artery can be complicated by the increase in cardiac volume that takes place when extracorporeal circulation is discontinued. inadequate or excessive allowance for this increase can cause undue tension on the grafts or troublesome kinking. this report describes an improved method of orienting vein bypass grafts to the right coronary artery which eliminates problems of incorrect measurement.2004305767

volume and shape of normal human spermatozoa.an improved apparatus for measuring the electrical size of particles, developed in this laboratory and based on the principle of the coulter counter, is used to size human spermatozoa. the typical size distribution is unimodel, with a skew to the right. the actual quantity determined by the measuring system is electrical size (i.e., shape factor x volume); in order to extract the volume, it is necessary to obtain an independence measure of particle shape. this is done by estimating the relative ...1977321264
cell-mediated immunity in experimental nocardia asteroides infection.experimental mycetoma-like lesions developed in guinea pigs after subcutaneous injection of nocardia asteroides. although delayed hypersensitivity appeared earlier, increased macrophage migration inhibition and microbicidal activity appeared after 7 weeks. when the lesions healed, high cell-mediated immunity was present. cell-mediated immunity was transferred to normal recipient guinea pigs from healed donor guinea pigs by spleen cell transfer. recipient guinea pigs showed marked protection agai ...1977321348
conservation of transfer ribonucleic acid and 5s ribonucleic acid cistrons in enterobacteriaceae.the genes for tranfer ribonucleic acid (tdna) and 5s ribonucleic acid (5sdna) were isolated from the total deoxyribonucleic acid (dna) of escherichia coli. the relatedness of tdna and 5s from e. coli and other species of enterobacteriaceae was determined by reassociation of the isolated genes labeled with 32po4 to unlabeled, unfractionated dna. double-stranded dna was separated from unreacted dna by hydroxyapatite chromatography. thermal elution profiles were done to determine the amount of unpa ...1977321428
