    Notizen: High-pressure Brillouin scattering measurements have been carried out in orientationally disordered (OD) phases I and I′ of solid HBr, which yielded the first determination of acoustic velocities for all directions, the refractive index, the polarizability, the density, adiabatic elastic constants (C11, C12, and C44), bulk modulus, and the elastic anisotropy as a function of pressure up to 7 GPa and at room temperature. The I→I′ phase transition in solid HBr was confirmed on the discontinuous pressure dependence at P=2.3 GPa for average errors of the least-squares fit by the analysis of in situ Brillouin spectroscopy. These elastic properties of solid HBr are compared with recent results in the OD phase I of solid HCl. We suggest that the form of the potential energy function for intermolecular forces in solid HBr is similar to that in HCl. © 1999 American Institute of Physics.

    Notizen: summary The purpose of this study was to investigate the correlation between maximal mouth opening and size of the skeleton. The subjects were dental students at the Dental School of the Health Sciences University of Hokkaido with no functional disorders of the masticatory system. The stature and maximal mouth opening were recorded in 29 males and 31 females. These subjects agreed to have a lateral cephalogram taken at the closed and maximal mouth opening positions. The correlations between the maximal mouth opening and the body height, mandibular length and mandibular angle were significant. The correlation between the maximal mouth opening and the movement of the condyle was also significant.

    Notizen: Abstract Wistar Imamichi rat and human respiratory cilia were examined with anti-dynein antibody (AD2), which is specific for sea urchin sperm flagellar dynein. AD2-labelled fresh-frozen normal rat and human cilia stained clearly by immunofluorescence and the peroxidase-antiperoxidase (PAP) technique. On immunoelectron microscopy, AD2 labelled the outer dynein arms of normal human cilia. Paraffin-embedded normal human cilia also stained by immunofluorescence, although not always clearly. Neither the cilia of WIC-Hyd male rats, an animal model of Kartagener's syndrome, nor human cilia from patients with primary ciliary dyskinesia (PCD) reacted positively by the immunofluorescence or PAP technique. Western blots of normal rat cilia yielded a single band of about 450 kDa. In conclusion, AD2 recognizes the outer arm dynein heavy chains of healthy cilia and may be useful in diagnosing and classifying PCD light microscopically especially when only paraffin-embedded specimens are available. This approach may be of potential use for better defining and classifying PCD.

    Notizen: Abstract We studied blood MIP-1α and IL-8 in 38 septic patients and 5 healthy volunteers. Both chemokines were undetectable in the healthy volunteers. In sepsis, serum MIP-1α was detected in 45% of the patients and IL-8 in 84%. The levels of MIP-1α, but not of IL-8, correlated with CRP, IL-6 and TNFα levels. Complication, including various organ failures and mortality, showed no correlation with serum MIP-1α levels. In contrast, we found increased levels of serum IL-8 in septic patients with disseminated intravascular coagulation, central nervous system (CNS) dysfunction or renal failure, and the mortality rate was higher in the IL-8-detectable group than in the IL-8 undetectable group (50% vs 0%,p〈0.05). In conclusion, the production of both MIP-1α and IL-8 was increased and initially detectable levels of circulating IL-8 predicted high mortality in sepsis. Objective To determine the significance of the C-C chemokine MIP-1α and the C-X-C chemokine IL-8 in sepsis. Design Prospective study. Setting Clinical investigation, emergency department and general intensive care unit of university hospital. Patients and participants 38 septic patients and 5 healthy volunteers were studied. Sepsis was diagnosed following the criteria formulated by ACCP/SCCM. Interventions 10–20 ml of blood was drawn from each patient at the time of initial diagnosis of sepsis. Measurements and results MIP-1α and IL-8 were determined by sand-wich ELISA. Both chemokines were undetectable in the healthy volunteers. In sepsis, serum MIP-1α was detected in 45% of the patients and IL-8 was detected in 84%. The levels of MIP-1α, but not of IL-8, correlated with CRP, IL-6 and TNFα levels. Complications, including various organ failures and mortality, showed no correlation with serum MIP-1α levels. In contrast, we found increased levels of serum IL-8 in patients with disseminated intravascular coagulation (DIC) (p〈0.05), central nervous system (CNS) dysfunction (p〈0.05), renal failure (p〈0.01) and the mortality rates were higher in the IL-8 detectable group than in the IL-8 undetectable group (50% vs 0%,p〈0.05). Conclusions The production of MIP-1α and IL-8 was increased in sepsis. Furthermore, an initially detectable level of circulating IL-8, but not MIP-1α, predicted a high mortality in sepsis diagnosed according to the ACCP/SCCM criteria.

    Notizen: Abstract. Irradiation is suspected to injure inflammatory cells, such as neutrophils and mononuclear phagocytes, cells known to contribute to the development of acute lung injury (ALI). This study examined whether preexposure to x-ray irradiation modifies ALI induced by E. coli injected intravenously in guinea pig. Thirty animals were divided into two control and two irradiated subgroups: the first control group received saline only (n= 8), and the second control group received E. coli, 2 × 109/kg body weight, suspended in saline (n= 6), IV. The first irradiated group received a single 12-Gy dose + saline (n= 6), and the second irradiated group received a single 12-Gy dose +E. coli (n= 10). The lung wet-to-dry-weight ratio (W/D) and 125I-albumin lung tissue/plasma ratio (T/P) were measured as markers of lung injury. W/D was significantly higher in the control E. coli group than in the other groups. T/P in the control E. coli group was also increased compared with T/P measured in the other groups. In the control E. coli group, a marked increase in bronchoalveolar lavage (BAL) neutrophils was observed compared with the control saline group. However, no significant difference in BAL neutrophil counts was observed between the control and irradiated E. coli groups. In contrast, BAL macrophages were significantly reduced in the irradiated E. coli groups compared with the control E. coli group. These findings suggest that x-ray irradiation attenuates E. coli–induced ALI in guinea pigs, an effect explained, at least in part, by a reduction in the number of alveolar macrophages.

    Notizen: Abstract An isoleucine/valine polymorphism was observed at codon 1464 of the ATP7A gene, which is thought to encode a copper transporting adenosine triphosphatase (ATPase). The frequency of Val1464 was estimated to be 5.7% in the Japanese population. This polymorphism may be useful in genetic studies of Menkes disease.

    Notizen: Abstract Carnitine/acylcarnitine translocase (CACT) transports acylcarnitines into mitochondria in exchange for free carnitine, and is therefore an essential component within the fatty acid beta-oxidation pathway. CACT deficiency is an autosomal recessive disease caused by a mutation of the CACT gene. We have identified two novel mutations of the CACT gene in a patient with CACT deficiency. The first, a deletion mutation (146 del T), leads to premature termination and results in a very immature CACT protein. The second, a splicing mutation (261-10T〉G), results in either skipping of exons 3 and 4, or of exon 3 alone, and leads to truncation of the protein. Each of these mutations is hypothesized to destroy the function of the CACT protein. We propose that each of these mutations of the CACT gene play a causative role in the disease.

    Notizen: Abstract The degrees of nuclear spin polarization of 8,12B, 9C, 12N, 13O, 20,21F, 23Mg, 27Si and 39Ca produced in the high energy 12,13C, 16O, 22Ne, 24Mg, 28Si and 40Ca ions on Be collisions have been measured systematically, for the technical developments of the nuclear moment studies as well as the hyperfine interaction studies by means of β-NMR technique. The fragment momentum dependences were well reproduced by the simple kinematical model. Incident energy dependence and the mass dependence as well as the reaction angle dependences were qualitatively explained by the mixing of the near and far side collisions.

    Notizen: Abstract The β-NMR spectra of 21F, 23Mg, 27Si and 39Ca which were produced in heavy ion collisions and implanted in various crystals have been observed. The magnetic moments of 21F and 27Si were determined to be |μ(21F)| = 3.9194 ± 0.0012 μN and |μ(27Si)| = 0.8653 ± 0.0003 μN, respectively. The electric quadrupole coupling constants were determined for the first time to be |eqQ(21F in MgF2)/h|= 9.94 ± 0.09 MHz, |eqQ(23Mg in MgF2)/h|= 1.96 ± 0.06 MHz, |eqQ(27Si in Al2O3)/h|= 1.90 ± 0.12 MHz, |eqQ(39Ca in CaCO3)/h|= 0.60 ± 0.04 MHz. From the present eqQ/h, the Q moments were deduced as |Q(21F)|= 110 ± 22 mb, |Q(23Mg)|= 114 ± 3 mb, |Q(27Si)|= 60 ± 13 mb and |Q(39Ca)|= 36± 7 mb. The present data were compared with the theoretical values obtained by the OXBASH shell model code.
