Hypothalamic suprachiasmatic nucleus (SCN) is a circadian pacemaker which controls diurnal behavioral and hormonal rhythms in mammals. The SCN receives environmental light signals through the retinohypothalamic tract, and glutamate is the major excitatory neurotransmitter in the retinohypothalamic tract. In the present study, we investigated the developmental expression of the mRNAs for N-methyl-D-aspartate type glutamate receptor (NR)1, NR2A, NR2B and NR2C subunits in the rat SCN using in situ hybridization with specific riboprobes. At postnatal day 2 (P2), P8, Pl5 and P45, the high level of NRI transcripts was observed in both ventrolateral and dorsomedial subdivisions of the SCN, and the distinct expression of NR2C mRNA was principally found in the dorsomedial SCN. The weak NR2B mRNA expression was clearly found in both subdivisions of the SCN at P2 and P8, whereas specific NR2B hybridization signals were not found at Pl5 and P45. There was no specific hybridization signal of NR2A in the SCN throughout the postnatal life. These findings implicate that NR may play an important role in the neonatal SCN. In addition, this study suggests that NR1, NR2B and NR2C might be the major NR subunits in the developing SCN, whereas NRI and NR2C could be the subunit components of NR in the adult SCN.

This study is designed to evaluate the effect of low-dose whole body irradiation (WBI) for treatment of myasthenia gravis(MG) and changes of immunological parameters. According to MG protocol of low dose WBI, eleven patients were selected and followed up for at least one year. Clinical status and immunological parameters were assessed at the time of pretreatment (baseline) and 1, 2, 3, 6, 12 months after initial dose irradiation. The improvement began five weeks after WBI and lasted for 12-month follow-up in 7 patients (good responders) Clinical improvement and immunological changes were more pronounced in good responders. So, it is suggested that low dose WBI may have the role in the treatment of the MG as an another therapeutic modality.

Helicobacter pylori-eliminating effects of FEMY-R7, composed of fucoidan and evening primrose extract, were investigated in mice and humans. Male C57BL/6 mice were infected with the bacteria by intragastric inoculation (1x10(9) CFU/mouse) 3 times at 2-day intervals, and simultaneously, orally treated twice a day with 10 or 100 mg/kg FEMY-R7 for 2 weeks. In Campylobcter-like organism-detection test, FEMY-R7 markedly reduced the urease-positive reactivity. In a clinical sudy, human subjects, confirmed to be infected with Helicobacter pylori, were orally administered twice a day with a capsule containing 150 mg FEMY-R7 for 8 weeks. FEMY-R7 significantly decreased both the Delta over baseline-value in urea breath test and the serum pepsinogens I and II levels. The results indicate that FEMY-R7 not only eliminates H. pylori from gastric mucosa of animals and humans, but also improves gastric function.

PURPOSE: Excessive scarring in the forms of keloid and hypertrophic scar could be a consequence of the accumulation of granulation tissue cells due to aberrant control of apoptosis. Verapamil retard extracelluar matrix production and inhibits VEGF production in primary cultured keloid fibroblast. The object of this study is to identify the effects of verapamil on VEGF expression and apoptosis in early wound scarring of the rabbit ear. METHODS: Full thickness wounds were created on the ventral side of 6 New Zealand rabbits's ear. 16 days after initial wounding verapamil and saline were injected on each scars, and the scars were harvested for 1 week, 2 weeks, and 4 weeks. The wounds were stained with hematoxylin and eosin, TUNEL stain, immunohistochemical stain for VEGF and calculated scar elevation index. RESULTS: Histologic analysis demonstrated significant reduction in inflammation, vascularity and improvement in dermal collagen organization in experimental group. In TUNEL staining apoptosis positive cells were increased and immunohistochemial staining of VEGF demonstrated significant reduction of VEGF expression in experimental group. No significant difference was noted in scar elevation index between two groups. CONCLUSION: This study suggest that intralesional injection of verapamil on early wound scarring of the rabbit ear decreased VEGF production and increased apoptosis and have a benefit on the pathophysiology of scar formation.

In this study we estimated a geometric correlation among digitally reconstructed radiographic image (DRRI), kV x-ray image (kVXI) from the On-Board Imager (OBI) and electric portal image (EPI). To verify geometric correspondence of DRRI, kVXI and EPI, specially designed phantom with indexed 6 ball bearings (BBs) were employed. After accurate setup of the phantom on a treatment couch using orthogonal EPIs, we acquired set of orthogonal kVXIs and EPIs then compared the absolute positions of the center of the BBs calculated at each phantom plane for kVXI and EPI respectively. We also checked matching result for obliquely incident beam (gantry angle of 315 degrees) after 2D-2D matching provided by OBI application. A reference EPI obtained after initial setup of the phantom was compared with 10 series of EPIs acquired after each 2D-2D matching. Imaginary setup errors were generated from -5 mm to 5 mm at each couch motion direction. Calculated positions of all center positions of the BBs at three different images were agreed with the actual points within a millimeter and each other. Calculated center positions of the BBs from the reference and obtained EPIs after 2D-2D matching agreed within a millimeter. We could tentatively conclude that the OBI system was mechanically quite reliable for image guided radiation therapy (IGRT) purpose.

BACKGROUND: To evaluate the efficacy of EMG biofeedback and pelvic floor electrical stimulation in the stress urinary incontinence patients by Kontinence HMT2000. MATERIALS AND METHODS: A group of 14 patients with stress urinary incontinence were treated with combined biofeedback and intravaginal electrical stimulation during 12 sessions from 2 weeks to 6 weeks. RESULTS: At immediate post treatment, subjective cure rate was 28% and improvement rate was 57% and failure rate was 15%. Thus the overall success rate for this treatment was 85%. The result of 3 months after treatment showed cure rate 14% and improvement rate was 43%. Intravaginal pressure increased by an average of 11.9 cmH2O. Increased vaginal pressure was found in 93% of the patients and more than 50% increment of intravaginal pressure was 71%. CONCLUSIONS: Combined biofeedback and pelvic floor electrical stimulation by use of Kontinence HMT2000 is effective for the patients who have good compliance, relative low degree stress urinary incontinence. In order to attain good results, a well structured program that teaches specific muscle exercise and the patients should be followed by regular interval reinforcement treatment.
