Objectives : Meridian Scraping Therapy(MST: Kwal-Sa: 刮痧) has not well known in Korea. But it's a kind of Traditional Physical Therapy wide spreaded in China and Taiwan. So I want to introduce this new Therapy by summarizing the basic theories and practical manipulations. Conclusions : To analyse the meaning of the character Kwal-Sa, Kwal(刮) means scraping the skin by some tools and Sa(痧) means originally the red spots on skin of measles but in this therapy it's the red spot on skin after the treatment. Meridian Scraping Therapy is based on the meridiology and holism which are the basic theory of Oriental Medicine. The main effects of Meridian Scraping Therapy are draining of pathogenic factors, promoring the flow of ki and blood, tonify yang, balancing the harmony of intemal organs and enhancing the immuno-ability in body. Rhinoceros corpus is common matrial of MST-plate which is the tool of manipulation. And by this plate several manipulation is performed according to the symptom and the locations of pain. The merits of MST are that easily learned by practician, the effects of the treatment are very quickly manifest and no significant side-effects. And additionally this therapy performed not only for treat diseases but prevent it and preserve health.

The defects of the abdominal wall could be brought about either congenitally, for instances in such cases as omphalocele or gastroschisis, or by various acquired causes-trauma, excision of tumors, excision of burn scar, tissue necrosis caused by infection, hematoma after abdominal surgery, tissue necrosis after radiation therapy and so on. As for the techniques of the reconstruction of the abdominal wall defects, many authors have developed and reported diverse methods. To summarize, primary closure, skin graft, local skin flaps, various myocutaneous flaps, free flap, fascia graft, artificial mesh, tissue expansion, etc could be used in the reconstruction of the abdominal wall defects. The periumbilical perforator-based island skin flap has a many advantages such as no significant sacrifice of the rectus abdominis muscle, wide rotation arc, reliable blood flow of the perforator, short elevation time for flap, and for middle-aged, obese patients, the donor site may be the best from the cosmetic point of view. We used perforator-based island skin flap in 5 cases with reasonable result from March 1999 to May 2001. There were no significant complications and donor sites could be repaired primarily.

The safety of cosmetics or cosmetic ingredients on human skin is generally evaluated by visual assessment but some early subtle skin changes may not be noticed by the naked eyes. Thus, the present study was conducted to detect skin reactions induced by mildly irritating cosmetic ingredients by using a laser Doppler perfusion imager (LDPI) method that measures blood flow, a $Vapometer^{(R)}$ that measure strans epidermal water loss (TEWL), and a spectrophotometer that measures the skin color as the erythema values ($a^*$). Visual assessment showed that all tested oils and humectants except propylene glycol belong to the low skin irritation ranges (grades 0+ to 2.9+) while all tested surfactants and propylene glycol belong to the moderate-to strong-skin irritation ranges (grades 3+ to 5+). Among three instrumental methods, TEWL assessment appeared to be more sensitive than spectrophotometric or LDPI method and suitable for the detection of subtle skin response invisible to the naked eye (grades 0+ to 2.9+). Skin reactions of grade 3+ to 5+ could be detected by all three instrumental methods. In conclusion, the current study suggested that the sub-clinical skin reactions due to mild irritants contained in cosmetics can be best assessed by TEWL measurements.

Purpose: As the soft tissue defect around the knee is difficult to reconstruct, local flap or free flap is used. Distally based anterolateral thigh pedicled flap introduced by Zhang uses sufficient reverse flow supplied from the vascular network around the knee. We report successful reconstruction of defect around knee by this method. Methods: Four patients with skin & soft tissue defect around knee have been treated for reconstruction using the distally based anterolateral thigh pedicled flap. First, the doppler was used to check the perforator flap of the descending branch of the lateral circumflex femoral artery and to draw and dissect the perforator flap as much as needed. After the dissection, the proximal of the descending branch was clamped and checked for sufficient supply of blood flow from the reverse flow and then ligated. It was dissected along the descending branch and in order to prevent damage to the joined parts of the descending branch and the lateral superior geniculate artery, a more careful ligation was done starting from 10 cm superior to the knee. The defect was reconstructed after securing enough vascular pedicle to cover all the damaged parts. Results: Not all patients suffered from flap necrosis. In case of the patient with chronic osteomyelitis, slight venous congestion was observed right after the surgery but it disappeared the following day. All three patients had no occurences of additional complications. Conclusion: Distally based anterolateral thigh pedicled flap was enough to provide large flap for knee reconstruction. It had sufficient blood flow and vascular pedicle. It also had taken short operation time compared to the free flap operation. The distally based anterolateral thigh pedicled flap used by the authors is a very useful way of reconstructing the area around knee.

Objective : Some neurosurgeons intentionally ligate the branches of the superficial temporal artery (STA) that are not used in standard STA-to-middle cerebral artery (MCA) anastomosis for the purpose of improving the flow rate in the bypass graft. We investigated changes in bypass flow during temporary occlusion of such unused branches of the STA. Methods : Bypass blood flow was measured by a quantitative microvascular ultrasonic flow probe before and after temporary occlusion of branches of the STA that were not used for anastomosis. We performed measurements on twelve subjects and statistically assessed changes in flow. We also examined all the patients with digital subtraction angiography in order to observe any post-operative changes in STA diameter. Results : Initial STA flow ranged from 15 mL/min to 85 mL/min, and the flow did not change significantly during occlusion as compared with preocclusion flow. The occlusion time was extended by 30 minutes in all cases, but this did not contribute to any significant flow change. Conclusion : The amount of bypass flow in the STA seems to be influenced not by donor vessel status but by recipient vessel demand. Ligation of the unused STA branch after completion of anastomosis does not contribute to improvement in bypass flow immediately after surgery, and furthermore, carries some risk of skin necrosis. It is better to leave the unused branch of the STA intact for use in secondary operation and to prevent donor vessel occlusion.

Recently, the incidence of pressure sore has been increased, due to increased number of patients with central nervous system injuries after traffic and industrial accidents or with long term loss of consciousness due to drug intoxication. The management of sacral pressure sore has been improved through the development of myocutaneous flap. However, sacrifice of the deep muscle cause some problems such as intraoperative bleeding, functional disabilities of donor site and further limitation of reconstruction for recurrent pressure sores in paraplegic patients. The development of perforator-based island skin flap introduce a new treatment modality for sacral pressure sores. We used perforator-based island skin flap in 15 cases with reasonable result from January 1998 to February 2000. This flap has a many advantages such as no significant sacrifice of the gluteus maximus muscle, wide rotation arc, reliable blood flow of the perforator, short elevation time for the flap, and no post-operative hindrance to walking in patients who are not paraplegic. There was no significant complication without significant sequelae and donor sites could be repaired primarily.

This study has evaluated the physiological reaction to wearing brassiere as well as the sensations that the wearer feels in order to understand the effect of brassiere use on the human body. Six healthy women in their twenties were used as subjects and the experiment measured the difference in their S.C.L, Skin Temperature, B.V.P and Pulse. The measurements were made in the following conditions: Women not wearing any brassiere, women wearing sports brassiere, and the women wearing wire brassiere. The results showed significant differences in the following areas. 1. S.C.L was found to be the highest when they didn't wear any brassiere, followed by when they wore wire-brassiere and then sports brassiere. 2. The Skin Temperature was found to be the highest when they wore wire-brassiere, followed by when they wore sports brassiere and when they didn't wear any of them. In particular, when they wore sports brassiere, the B.V.P was found to be the highest when they wore none of them, fir skin temperature dropped as time passed. 3.ollowed by when they wore sports brassiere and then wire brassiere. When they wore sports brassiere, they had irregular blood-flow. 4. Pulse was found to be the highest when they didn't wear any of them, followed by when they wore sports brassiere and then wire brassiere. 5. Those who didn't wear any brassiere felt the most chill, followed by those wearing wire brassiere and then sports brassiere. The moisture level was found to be the highest when they wore sports brassiere, followed by when they wore wire brassiere and then when they wore none of them. Comfort level was found to be the best with no brassiere, followed by wire brassiere and then sports brassiere.

Microsurgical free-tissue transfer has allowed surgeons to salvage injured limbs but choosing appropriate healthy recipient vessels has proved to be a difficult problem. Retrograde flow flaps are established in island flaps. Retrograde flow anastomosis could prevent the possible kinking and twisting of the arterial anastomosis. By not interrupting the proximal blood flow to the fracture or soft tissue defect site, the compromise of fracture or wound healing might be prevented. We wished to estabilish an animal model in rat for a retrograde arterial flow based free flap. Nembutal-anesthetized male rats; weighing 250 to 300 gm, were used. The femoral artery and common carotid artery were exposed and divided. The systemic and retrograde arterial pressure were quantified by utilizing a parallel tubing system connected with peripheral arterial line. In this study, the retrograde flow was not pulsatile and the retrograde arterial pressure was 64-65mmHg, with a mean arterial pressure of 106-109mmHg. An epigastiic skin flap, measuring $3{\times}3cm$, was raised with its vascular pedicle. The epigastric free flap was transfered in the same rat from femoral vessels to carotid vessels in end to end fashion. We anastomosed the donor arteries to the distal parts of the divided recipient arteries and the donor veins to the proximal parts of the recipient veins. Twelve experiments were performed and the transplantations succeeded in 75 percent of them. In the remaining 25 percent, the experiments failed due to thrombosis at the site of anastpmosis, or other causes. This animal model represents an excellent example of retrograde arterial flow free flap transfer that is reliable.

This study was conducted to identify the structure of the sensibility and autonomic nervous responses to odor by ages. 72 participants, 24 each in their teens, twenties, and thirties were given odor stimuli, cederwood, grapefruit, teebaum, peppermint, rose. During the presentation of stimuli, participant were measured blood flow, skin temperature, skin conductance, and ECG and subjective emotion to each odor were evaluated, Five factors, aesthetic, intensity, naturality, uniqueness, and romantism were identified but there were no differences by ages. Emotional factors that predict the preference to certain odors turned out partly different by ages. However, odors that made participants feel sick created more autonomic nervous response than odors that made them feel good.

Various methods have been proposed for enhancing the contrast of laser speckle contrast image (LSCI) in subcutaneous blood flow measurements. However, the LSCI still suffers from low image contrast due to tissue turbidity. Herein, a physicochemical tissue optical clearing (PCTOC) method was employed to enhance the contrast of LSCI. Ex vivo and in vivo experiments were performed with porcine skin samples and male ICR mice, respectively. The ex vivo LSCIs were obtained before and 90 min after the application of the PCTOC and in vivo LSCIs were obtained for 60 min after the application of the PCTOC. In order to obtain the skin recovery images, saline was applied for 30 min after the application of the PCTOC was completed. The visible appearance of the tubing under ex vivo samples and the in vivo vasculature gradually enhanced over time. The LSCI increased as a function of time after the application of the PCTOC in both ex vivo and in vivo experiments, and properly recovered to initial conditions after the application of saline in the in vivo experiment. The LSCI combined with the PCTOC was greatly enhanced even in deep vasculature. It is expected that similar results will be obtained in in vivo human studies.
