The physical characteristics of the light reflexes of the nasal tip are defined in large part by the studio lighting configuration. By varying the lighting configuration, it is possible to alter the light reflexes as regards their number, distance apart, symmetry, and size. For the plastic surgeon, the quarter light system of the medical photographer has definite advantages over the key light system of the portrait photographer. The quarter light system consists of two lights of equal intensity with symmetrical angles of incidence placed at 45 degrees to the camera-subject axis. Measuring changes in the light reflexes as a method of determining the efficacy of surgical techniques is valid under very controlled conditions. 相似文献

Phenylhydrazine treatment produced an expansion of spleen CFU (10 x N) and an even greater expansion of spleen ACFU (40 x N). Blood CFU and ACFU levels also increased. While marrow CFU did not change marrow ACFU showed a pronounced drop. The ratio of ACFU/CFU varied between tissues, it was highest in marrow and lowest in peripheral blood. The changes in CFU, ACFU and blood granulocytes are discussed in relation to the radioprotective action of phenylhydrazine pretreatment of mice. 相似文献

Teichoic acid-associated N-acetylglucosamine and rhamnose have been shown to serve as phage receptors in Listeria monocytogenes serotype 1/2a. We generated and characterized two single-copy Tn916DeltaE mutants which were resistant to phage A118 and several other serotype 1/2a-specific phages. In one mutant the insertion was immediately upstream of the recently identified ptsHI locus, which encodes two proteins of the phosphoenolpyruvate-dependent carbohydrate uptake system, whereas in the other the insertion was immediately upstream of an operon whose most distal gene was clpC, involved in stress responses and virulence. Transduction experiments confirmed the association of the phage-resistant phenotype of these mutants with the transposon insertion. Phage A118 resistance of the mutants could be attributed to inability of the phage to adsorb onto the mutant cells, and biochemical analysis of cell wall composition showed that the teichoic acids of both mutants were deficient in N-acetylglucosamine. Rhamnose and other teichoic acid and cell wall components were not affected. 相似文献

The rates of school injuries were examined by means of a prospective study of 212 schools during the 1981-82 school year. The results showed an annual incidence rate of 5.4 injury events/100 children, which appears to be an underestimate of the actual rate. Of all the injury events 28.7% resulted in serious injuries. Injuries were significantly more frequent in the elementary as opposed to the secondary schools, and the boys were injured significantly more often than the girls. Most of the injuries occurred during athletic activities. Most of the children with either serious or minor injuries were sent to the school office or returned to the classroom, which indicates that the present level of first-aid training among school personnel is inadequate. 相似文献

Chiral fluorine-tagged sulfoxides of known absolute configuration have been synthesized. These compounds are required as reference standards to validate a 19F NMR-based micromethod for the stereochemical analysis of biosynthetic fatty acyl sulfoxides. 相似文献
