Objectives : To understand the motor recovery pattern after spinal cord injury, We designed the quantitative measuring method of locomotion recovery using computerized motion analysis combined with video recordings. Materials and Methods : Using computerized motion analysis technique, locomotions of the 10 cord-hemisected Sprague-Dawley rats on the treadmill were graphically analyzed. Patterns of foot trajectories were plotted on two dimensions before and after unilateral spinal cord hemisecion at T7 level. Result : Immediately following dorsal hemisection, patterns of foot trajectories altered dramatically. Walking speed, stride length and height of hindfoot movements were markedly reduced. Coordination of left and right hindlimb was also disrupted. Although the lesions were unilateral, locomotor behavior was distrubed bilaterally. However, by six weeks, stride length and coordination of hindlimbs returned to near normal but vertical movement of the hindlimb recovered very little. Forelimb-hindlimb coordination was also initially disrupted but partially returned within three weeks. Conclusion : Computerized motion analysis is a sensitive technique for the detection of minor motor deficits following nerve injuries.

Background and Objectives: The role of different Galectins in the pathogenesis of different types of malignancy is being profoundly investigated recently. In this study, the author investigated the level of Galectin-1 and -7 in the layngeal squamous cell carcinoma tissue to define its relationship to the tumor progression. Materials and Methods: Paraffin-embedded tissue specimens from 77 patients, who were diagnosed as laryngeal squamous cell carcinoma from 1993 to 2007, were immunohistochemically stained for Galectin-1 and -7. Results: Galectin-1 expression was positively correlated with tumor stage and nodal involvement. Galectin-7 expression was increased in better differentiated tumors. Conclusion: Expression of Galectin-1 and -7 can be used as a valuable indicator in laryngeal squamous cell carcinoma under certain limitations.

This study was conducted to have basic and applied informations to establish the cultivation method and to improve the cultivation techniques of Angelica gigas Nakai through investigating the rates of germination and seedling establishment with treatment of plant growth regulator and seed priming. The germination rates of round shape seed were about 0.3~12% higher than those of parallel shape. The germination rates with different storage durations were increased at the level of 25oC and 4oC with the storage days, while they were clearly higher at -20oC compared to those at 4oC and 25oC without the storage durations. With the results of germination rates with treating of plant growth regulator and seed priming, their rates with the round shape seeds were comparatively higher about 6% than those with parallel shape seed and they were increased with increasing of the storage durations. The germination rates were generally appeared higher with GA3 than did those with seed priming. The highest germination rate was appeared at 50 ppm GA3 of plant growth regulator and at -0.5 MPa PEG6000 of seed priming. The germination rates?ㅤ ?ㅤ of Angelica gigas were different with different temperature, storage durations and the treatments of plant growth regulator and seed priming. These results could be used according to different cultivating conditions.

The Eryshrocyte Sedimentation Rate on the students of Seoul National Uuiversity was discussed corelating with X-ray findings for tuberculosis mass suruey. 1) Among the students of Seoul National University, 4727 were examined by miniature radiogram and the morbidity of active tuberculosis was shown 1.7 percent 616 of students were examined by both miniature radiogram and blood sedimentation reaction and the morbidity was 2.9 per cent. 2) The screening procedure by blood sedimentation reaction in addition to miniature radiogram could prevent missing around one fourth of active cases This means that E.S.R. has a great significance on the screening procedure for tuberculosis case findings. 3) Abnormal E.S.R. was shown on 75,5 percent of active cases. Persons whose E.S.R. are beyond 3mm for 30minutes and 10mm for 60minutes are suspected tuberculosis and should be required further examination. 4) The distribution rate of E.S.R. of between 0∼6.5mm was shown on 80percent of these students who were examined and that of between 0∼10mm was shown on 88.7 percent of students. The mean was 4.8mm. Hereby it is recommended That E.S.R. must be employed as one part of the useful methods on the mass screening survey for tuberculosis. furthermore it should be recalled that most of the Korean youths show tuberculin test positive. This fact requires such procedure as blood sedimentation reaction in addition to X-ray photography urgently on the epidemiological tuberculosis survey.

Objective : Because the cause and etiology of chronic headache are not yet fully explained, the treatment of this symptom is not simple. In order to study the effectiveness East-West pain treatment on chronic headache, we evaluated its effect of pain alleviation and quality of life improvement on chronic headache patients who were treated with nerve block and acupuncture, and only acupuncture for eight weeks. Methods : 92 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified into two groups, nerve block and acupuncture group(EW group, n=49) and acupuncture group(E group, n=43). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of two groups were analyzed using VAS scores and BPI(Brief Pain Inventory). Results : The VAS and BPI after four weeks of treatment showed significant improvement among two but differences between the three groups was statistically insignificant. The VAS and BPI of the EW group after eight weeks of treatment showed statistically significant improvement compared to the other two groups. Conclusion : The pain treatment for chronic headache might be contributed to improvement of quality of life as well as alleviation of pain of chronic headache patients. It was suggested that the West pain treatment in combination with East pain treatment might be an useful modality to improve the pain and quality of life in chronic headache patients.

Objective : The purpose of this study was to assess the effect of acupuncture treatment for chronic headache patients using power spectrum analysis of the heart rate variability(HRV). Methods : 15 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of acupuncture treatment were analyzed using power spectrum analysis of the HRV, HRV was recorded before and after acupuncture treatment. Results : HRV before and after treatment was compared after 8 weeks of acupuncture treatment. Increase in mean values of SDNN and RMSSD were observed but the increases were not statistically significants. Increase in mean values of TP, LF and HF were observed but, the increase was significant(p<0.05) only in TP. Conclusions : The results suggest that acupuncture treatment on chronic headache patients can increase the activity of autonomic nervous system. Further use of HRV for quantitative analysis of acupuncture treatment on autonomic nervous system related symptoms is suggested.
