  • Brown tumor is the benign bone lesion consists of woven bone and fibrous tissue without matrix, which develop due to chronic excessive osteoclastic activity such as hyperparathyroidism. Usually they appear with normal uptake or occasionally focally increased uptake on bone scan. We present a case with brown tumor shown more increased uptake and more number of lesions on bone scan after parathyroidectomy, and lesser increased uptake on serial bone scans without any other treatment through several months. This finding is thought to be similar to 'flare phenomenon' which is occasionally seen after treatment of metastatic bone lesions of malignant cancer, and may represent curative process of brown tumor with rapid normal bone formation.

  • While major solar proton events (SPEs) come from the coronal mass eject (CME)-driven shocks in solar wind, there are many evidences that potentiality of CMEs to generate SPEs depends on its early evolution near the Sun and on different solar activities observed around the CME liftoff time. To decipher origin of SPE release, we have investigated onset time comparison of the SPE with CME, metric type II radio burst, and hard X-ray flare. For this, we select 30 SPEs observed from 1997 to 2006 by using the particle instrument ERNE onboard SOHO, which allows proton flux anisotropy measurement in the energy range ~10 - 50MeV. Onset time of the SPEs is inferred by considering the energy-dependent proton transport time. As results, we found that (1) SPE onset time is comparable to that of type II but later than type III onset time and HXR start time, (2) SPE onset time is mostly later than the peak time of HXR flare, (3) almost half of the SPE onsets occurred after the HXR emission, and (4) there are two groups of CME height at the onset time of SPE; one is the height below 5 Rs (low corona) and the other is above 5Rs (high corona). In this talk, we will present the onset time comparison and discuss about the origin of the SPE onset.

  • Recently, we suggested a CME earthward direction parameter as an important geoeffective parameter that has been demonstrated by front-side halo CME data. In this study, we present the geometrical implication of this parameter by comparing with the parameters from a CME cone model. Major results from this study can be summarized as follows. First, we derive an analytic relationship between the cone model parameters(the half angular width of a cone and the angle between the cone axis and the plane of sky) and the earthward direction parameter. Second, we demonstrate a close relationship between the earthward direction parameter and the cone axis angle using 32 front-side full halo CMEs. Third, we found that there is noticeable inconsistency between the cone axis angles estimated from the cone model fitting to the CMEs and from their associated flare positions, implying that the flare position should not be considered as a good earthward direction parameter. Finally we present several advantages of our earthward direction parameter in terms of the forecast of a geomagnetic storm based on CME parameters.

  • In an attempt to investigate star formation activity and statistical properties of clumps of high Galactic latitude clouds (HLCs), we mapped the Polaris Flare region, PF121.3+25.5, in $^{12}CO\;and\;^{13}CO$ J = 1 - 0 using SRAO 6-m telescope and also observed its 12 $^{13}CO$ peak positions in CS J = 2 - 1 with TRAO 14-m telescope. $^{13}CO$ integrated intensity map shows clearly its clumpy structure and the locations of clumps well agree with $^{12}CO$morphology. CS line is not detected toward the 12 $^{13}CO$ peak positions, so we can conclude there are no dense $(\sim10^4\;cm^{-3})$ in this region. We decomposed 105 clumps from $^{13}CO$ map using GAUSSCLUMPS algorithm. The mass of clumps ranges from $7.8\;M_{\odot}\;to\;7.4{\times}10^{-2}\;M_{\odot}$ with a total mass of $66.4\;M_{\odot}$ The mass spectrum follows a power law, dN/dM ${\propto}\;M^{-\alpha}$ with a power index of ${\alpha}=1.91{\pm}0.13$. The virial masses of clumps are in the range of $10{\sim}100M_{LTE}$ and so these clumps are considered to be gravitationally unbound.

  • Objective : The purpose of this report is to know the effect of Sopung-san and Cheonggisamseup-tang(消風散 合 淸肌滲濕湯) on seborrheic dermatitis. Methods : We experienced one case of seborrheic dermatitis patient with Sopung-san and Cheonggisamseup-tang. To evaluate the effectiveness of this treatment, we used the Visual Analogue Scale(VAS) about symptoms of flare, itching, and observe scales. Results : After the treatment, the grade of flare and itching VAS was decreased, and clinical symptoms were improved including scales. Conclusion : The result indicate that Sopung-san and Cheonggisamseup-tang is helpful in the treatment of seborrheic dermatitis. And an author consider that additional clinical studies are needed to verify the effectiveness of herbal medicine with objective assessment tools.

  • Objectives : 'Obtaining qi(deqi)' is a sensation experienced by a patient or an acupuncturist during acupuncture treatment, and it is considered to be an important factor in acupuncture treatment. However, previous studies reported conflicting results about the relationship between 'obtaining qi(deqi)' sensation and the effect of acupuncture treatment. Also, most of the previous studies investigating 'obtaining qi(deqi)' and the acupuncture effect, dealt with the analgesic effect of acupuncture. The objective of this study was to analyze the relation between the 'obtaining qi(deqi)' and the anti-itching effect of acupuncture treatment. Methods : Twenty one healthy subjects participated in this study. At the first visit, itch was induced to all subjects using intradermal injection of histamine on the lower arm. At the second visit, acupuncture treatment was applied using LI11 and 'obtaining qi(deqi)' was assessed. After acupuncture treatment, itch was induced again, and itch VAS and skin flare were assessed. Results: At the 6,8,10 minutes after histamine injection, the change of itch VAS between before and after acupuncture treatment was significant. Among 'obtaining qi(deqi)', subjects reported that 'dull ache', 'pricking', 'heavy' were most strong. Total score of 'obtaining qi(deqi)' sensation was not related to the change of itch VAS or skin flare. The 'electric shock' sensation is related to the change of itch VAS, and 'bruised' and 'heavy' sensations were related to the change of skin flare. Conclusions : Total 'obtaining qi(deqi)' is not related to the anti-itching effect of acupuncture, but several sensations showed relationship with the effect of acupuncture on itch severity and skin flare. Further researches based on various symptoms or acupuncture points, are needed.

  • The .Japanese sun observing satellite, Yohkoh, has been operational for five years and her scientific instruments are still in good condition. They have revealed ample of evidences that solar flares were triggered by magnetic reconnection, which was, for the first time, clearly indicated to take place in the solar corona. Cusp structures in soft X-rays and a new type of hard X-ray sources at the top of flaring loops have strongly supported the scenario originally proposed by C-S-H-KP. Nonthermal energy input in hard X-rays and thermal energy estimated from soft X-rays are fundamentally consistent with the interpretation of thick-target and chromospheric-evaporation models (Neupert effect). X-ray jets, another discovery of Yohkoh, were also associated with magnetic reconnection, as a result of the interaction of emerging fluxes with pre-existing coronal loops. Temperature structures of active regions, quiet sun, and coronal holes had very dynamic differential-emission-measure (DEM) distributions and high-temperature tails of DEM were considered to come from the contribution of flare-like activity.
