to realize an excitation of electron Bernstein waves （EBW） via mode conversion from X-mode waves injected from the high magnetic field side （HFS）, new inner-vessel mirrors were installed close to a helicM coil in the large helicM device （LHD）. 77 GHz electron cyclotron （EC） wave beams injected from an existing EC-wave injection system toward the new mirror are reflected on the mirror so that the beams are injected to plasmas from HFS. Evident increases in the electron temperature at the plasma core region and the plasma stored energy were observed by the HFS beam injection to the plasmas with the line-average electron density of 7.5~ 1019 m-3, which is slightly higher than the plasma cut-off density of 77 GHz EC-waves, 7.35~ 1019 m-3. the heating efficiency evaluated from the changes in the time derivative of the plasma stored energy reached ,,~70%. Although so far it is not clear which is the main cause of the heating effect, the mode-converted EBW or the X-mode wave itself injected from the HFS, an effective heating of high-density plasma over the plasma cut-off of EC-wave was successfully demonstrated.

two-dimensional structure of density fluctuations is examined during the current jump phase, indicating a change from the open magnetic fields to the closed ones. During the smooth current ramp-up phase the two-dimensional contour of the LiI intensity shows vertically alignment, consistent with the magnetic surfaces. At the inflection point in Ip ramp-up the LiI intensity contour becomes flat in the observation regime and then suddenly a steep gradient and higher intensity regime are formed in the vertical direction. this higher intensity corresponds to a burst of LiI waveform. According to these changes in the contour, it is found that, within ~1 ms around the burst of LiI, a low frequency coherent wave with a long wavelength rapidly grows. the relations with other signals （magnetic flux and microwave stray power） are discussed with respect to the topological change in the magnetic configuration and mode conversion of the incident electromagnetic waves.

A long-pulse plasma discharge for more than 30 min. was achieved on the Large Helical Device （LHD）. A plasma of ne = 0.8 × 10^19 m^-3 and t10 = 2.0 keV was sustained with PICH = 0.52 MW, PECH = 0.1 MW and averaged PNBI = 0.067 MW. total injected heating energy was 1.3 G J, which was a quarter of the prepared RF heating energy. One of the keys to the success of the experiment was a dispersion of the local plasma heat load to divertors, accomplished by shifting the magnetic axis inward and outward.

Background: Infection with human herpesvirus 7 (HHV-7) generally results in a febrile illness with accompanying exanthema subitum. Objectives: to ascertain and describe the role of HHV-7 in a case of acute myeloradiculoneuropathy. Patient: A previously healthy young man with complaints of motor weakness, dysphasia, and nasal voice. Methods: Serological examinations were performed with the patient's serum. We also examined virus genome DNA in cerebrospinal fluid by regular and realtime polymerase chain reaction. Moreover, we checked the antiganglioside antibody level in the patient's serum samples by the immunoblot analysis. Results: Serological studies revealed significant change in titers of antibodies against cytomegalovirus, Epstein-Barr virus, and HHV-7, but only HHV-7 genome was detected in the cerebrospinal fluid, with its disappearance after therapy. No antiganglioside antibody was detected in the patient's serum. Conclusion: the unique clinical picture of the present patient might be closely related to the reactivation of HHV-7 in the nervous system.

Background: Paraneoplastic peripheral neuropathy is sometimes associated with unidentified neuronal autoantibodies. Objective: to examine the effects of serum from a patient with subacute sensory axonopathy on the function of the trk high -affinity nerve growth factor receptor. Patient: An 86-year-old man with sens ory neuropathy exhibiting an autoantibody to trk. Methods: Immunoblot analyses o f the brain homogenates and immunoprecipitation were performed with human sera. We further examined the effect of sera on nerve growth factor-induced neurite o utgrowth and trk autophosphorylation. Results: the patient showed sensory nerve axonopathy without well-known paraneoplastic autoantibodies. His serum inhibite d nerve growth factor-induced neurite outgrowth and trk autophosphorylation in PCtrk cells. Moreover, the patient’s serum, but not control serum, immunoprecip itated trk and recognized trk in brain homogenates as well as in trk immunopreci pitates. Conclusion: these data strongly suggest that an anti-trk autoantibody might cause subacute sensory neuropathy.
