    Notes: We have performed the fs pump–probe experiment on the B˜→a˜ nonadiabatic transition in the Hg–CO vdW complex. It is found that the transition occurs near the point where Hg and CO come nearest to each other on the B˜-state surface with a probability of 0.07 for their single encounter. This experiment serves as the first observation of the wave packet dynamics associated with an intermolecular energy flow in the vdW interaction. © 2000 American Institute of Physics.

    Notes: Using high silicon-iron single crystals containing around 6.5 wt. % silicon, the quenching temperature dependence of the saturation magnetization, the magnetocrystalline anisotropy constant, and the magnetostriction constants were measured at room temperature. The saturation magnetization and the anisotropy constant of the crystals with 4.9–6.0 wt. % silicon quenched into oil from 1100 °C showed decreases of up to 12 and 80%, respectively, compared to crystals cooled slowly from 1100 °C, while the saturation magnetostriction constants λ100 and λ111 increased for quenched crystals. The decreases in the saturation magnetizations and the anisotropy constants and the increases in the saturation magnetostriction constants for the quenched crystals were correlated with decreases in an order parameter calculated from x-ray measurements.

    Notes: Background Since dogs frequently develop allergic diseases, similar to those in humans, dogs represent a possible animal model for allergy in humans. In human atopic dermatitis (AD), CC chemokine receptor 4 (CCR4) has been shown to play an important role in the development of allergic inflammation of AD; however, the association between allergic reaction and CCR4 is not well understood in dogs.Objective To examine CCR4 expression in peripheral blood CD4+ cells in dogs that had AD and were experimentally sensitized with Japanese cedar pollen.Materials and methods Peripheral blood mononuclear cells (PBMCs) were isolated from 17 dogs with AD. The proportion of CCR4+ cells in peripheral blood CD4+ cells (CCR4/CD4) was evaluated by flow cytometry and compared with that in 10 healthy dogs. Similarly, in dogs that were experimentally sensitized to Japanese cedar pollen antigen, the proportion of CCR4/CD4 was examined pre- and post-sensitization.Results The proportion of CCR4/CD4 in dogs with AD was 40.3±3.3%, which was significantly higher than that in normal dogs (23.6±4.3%) (P〈0.01). In the experimentally sensitized dogs, the proportion of CCR4/CD4 was 25.4±2.6% at pre-sensitization and it was significantly increased (29.8±2.9%) at post-sensitization (P〈0.01).Conclusion The proportion of CCR4+ cells in peripheral blood CD4+ cells was measured in dogs with allergic conditions. The present findings indicate that CCR4+ cells may be involved in the pathogenesis of allergy in dogs as in humans.

    Effects of olopatadine hydrochloride, an antihistamine drug, on skin inflammation induced by repeated topical application of oxazolone in mice (2004)

    Notes: Background  Olopatadine hydrochloride (olopatadine) is one of the second-generation antihistamines, which is prescribed for allergic disorders such as rhinitis, urticaria and eczema dermatitis.Objectives  To investigate the possible anti-inflammatory effect of olopatadine on the chronic contact hypersensitivity response to repeated topical application of oxazolone in mice.Methods  The preventive and therapeutic effects of oral olopatadine were quantified by measurements of ear swelling, cytokine protein and mRNA expression in the ear lesion, and were compared with those of topical betamethasone 17-valerate (betamethasone).Results  The ear receiving repeated applications of oxazolone exhibited erythema, oedema and abrasion. Both preventive and therapeutic administration of olopatadine (10 mg kg−1 day−1) significantly inhibited the ear swelling and the increased production of interleukin (IL)-4, IL-1β, granulocyte-macrophage colony-stimulating factor (GM-CSF) and nerve growth factor. In the histopathological analysis, olopatadine ameliorated epidermal hyperplasia and infiltration of inflammatory cells. Consistent with these results, olopatadine significantly reduced the increased expression of interferon-γ and IL-4 mRNA. Although betamethasone (0·012 mg ear−1 day−1) showed similar activities to olopatadine against these responses, it caused atrophy of the ear skin.Conclusions  These results indicate that olopatadine is an antihistamine agent having inhibitory activities against chronic inflammatory dermatitis, possibly resulting from its diminishing effect on elevated cytokines.

    Dynamics of the spinal cord: an analysis of functional myelography by CT scan (1988)

    Notes: Summary The antero-posterior movement of the spinal cord with flexion and extension of the neck was analyzed in order to clarify the mechanism of spinal cord compression in cases with postoperative spinal deformity, and to contribute to the improvement of the surgical methods of conventional laminectomy. The control subjects were 47 cases without cervico-thoracic neurological symptoms, who underwent CT myelography in flexion and extension of the neck; the cervical spinal cord was examined in 27 of these cases and the thoracic cord in the other 20. CT myelography was also carried out in 16 patients with cervical myelopathy and in 5 patients after posterior decompression surgery (suspension laminotomy). CT sections in flexion and extension of the neck were analyzed for 1) change of configuration of the dura mater and the spinal cord, and 2) antero-posterior shift of the spinal cord in the subarachnoid space. In the control subjects, the configuration of the dura mater was slightly flattened at C5/6, C6 and C6/7 in extension of the neck. The cervical spinal cord shifted anteriorly in flexion and posteriorly in extension of the neck, and was flattened at the midcervical level in flexion in the control subjects. There was a statistically significant correlation between the location of the spinal cord and the adjacent intervertebral angles at the levels of C4, C5 and C6. These results were compared with the results from the 16 patients with cervical myelopathy and 5 patients after suspension laminotomy. The thoracic spinal cord shifted anteriorly in neck flexion and posteriorly in extension, especially at upper thoracic level. In order to avoid spinal cord compression due to anterior shift of the spinal cord caused by postoperative kyphosis, it is necessary to employ the surgical method which can prevent postoperative kyphotic deformity.

    A novel color M-mode Doppler echocardiographic index for left ventricular relaxation: depth of the maximal velocity point of left ventricular inflow in early diastole (2000)

    Notes: Abstract Color M-mode Doppler echocardiography (CMD) has been utilized in assessing left ventricular (LV) filling dynamics. We tested a novel CMD index, the depth of the spatiotemporal maximum of early diastolic inflow (D-maxV) in the left ventricle, to clarify its significance in assessing LV diastolic function. In 26 normal subjects and 32 patients with ischemic heart disease, D-maxV was determined with CMD as the distance from the mitral valve opening point to the center of the aliasing area in early diastole. Transmitral flow velocity was measured with pulsed Doppler. During routine catheterization, high-fidelity LV pressure measurements yielded diastolic variables in patients. D-maxV was significantly lower in the patients than the normals (13.0 ± 7.0 vs 23.4 ± 6.8 mm, P 〈 0.0001). D-maxV exhibited significant linear correlations with the minimal first derivative of LV pressure (r = 0.72, P 〈 0.01), the time constant of isovolumic relaxation (r = −0.67, P 〈 0.01), and LV minimal pressure (r = −0.53, P 〈 0.02) in the patients with wide ranges of peak early to late inflow velocity ratio (0.43–3.9) and deceleration time of early filling (79–293 ms). D-maxV showed an inverse correlation with LV end-diastolic pressure (r = −0.53, P 〈 0.02) and no significant correlation with mean pulmonary capillary wedge pressure. Moreover, Kaplan-Meier analysis focusing on the patients with myocardial infarction revealed that the group with D-maxV 〈 10.4 mm (n = 13) exhibited a lower cumulative cardiac event-free rate than that with D-maxV ≥ 10.4 mm (n = 14) (49.4% vs 92.9% at 5 years, P 〈 0.05). The depth of the spatiotemporal maximum of early diastolic LV inflow velocity reflects LV relaxation and is free of pseudonormalization. Evaluation of the LV relaxation separately from preload may have a prognostic value for myocardial infarction.
