이 증례 보고를 통해, 수배부 피부 이식 환자에 대한 환측 및 건측 상지의 전침 자극이 자극 직후 이식 부위 및 건측 수배부의 피부 혈류 순환을 각각 다른 양상으로 변화시킴을 확인할 수 있었다. 향후 전침자극이 피부 이식 부위의 미세혈류 순환을 증가시키고, 이식 부위의 재활 및 괴사 방지에 대한 임상적 효과를 나타낼 수 있는지에 대한 추가적 연구가 필요하다.

It has been known that the color of skin reflects the blood flow within. In lips, the capillaries close to the skin surface are numerous; hence lips are redder than the rest of face. However, dermatological research on lips is not as advanced as research on facial or body skin, and little was known about the relationship between relatively dull-colored lips and skin blood flow. The physiological differences between colorful and dull-colored lips were studied by a two-dimensional laser Doppler blood flow analyzer, a spectrometer for the measurement of the degree of oxygen saturation, and a confocal microscope for observing inside lips non-invasively. Dull-colored lips and the corner of lips (dull-colored compared to the center) showed relatively poor blood flow and lower oxygenated hemoglobin. It was found that colorful lips (generally the young) had a blood flow that tended to run straight in parallel with the skin surface. This unique blood-capillary structure can express clear red blood. Those with dull-colored lips had lost this unique structure. Their blood ran perpendicularly from the deep of the skin and down back again into the deep part as like the blood circulation patterns of facial skin. Therefore, the lips of the latter group had fewer blood capillaries near skin surface in the lips than that of the colorful-lips group. A lipstick containing a-glucosyl-hesperidin, which is derived from certain citrus fruits and can enhance blood circulation, was applied for evaluating its effects. Blood flow was increased 30 min after the application. After two weeks of daily application, the lips' condition became noticeably less dull. These findings suggest that the decrease of blood flow in dull-colored lips is caused by the loss of the unique capillary structure and the use of the lipstick to increase blood flow can give a vivid color to lips.

Purpose: The purposes of this study were to explain the phenomena of hot flashes in climacteric women by using Mexameter, Skin Thermometer, Corneometer, and Laser Doppler Perfusion Imager (LDPI) objectively and to identify the interrelation between the subjective and objective measurements of hot flashes by comparing the two as reported in retrospective questionnaires. Methods: The participants were one hundred women (45-60 yr) who were not currently on hormone therapy, and had reached hot flash scores of 10 or higher. Hot flashes were measured in a temperature and humidity controlled room for 7 hr from 10 am to 5 pm. Hot flashes were measured subjectively and recorded via the Hot Flash Diary Report. When participants felt the hot flashes, they were measured objectively by Mexameter, Skin Thermometer, Corneometer, and LDPI. Results: The frequency of hot flashes in participants ranged from 1 to 7 times. When hot flashes occurred in participants, the erythema, skin temperature, skin hydration, and blood perfusion showed statistically significant changes in all measurements. But, the subjective and objective measurements of hot flashes showed only weak correlations. Conclusion: Results indicate a need for future research with subjective and objective measuring instruments chosen depending variations identified for the study.

Objectives : This study was performed to evaluate the effects of moxibustion on cerebral blood flow, peripheral blood flow and blood pressure. Methods : We designed a randomized, cross-over study that included 20 healthy, male volunteers who were randomly assigned to one of two groups (the moxibustion group or the control group). The initial trial was followed by a washout period of one week before the groups were switched and the trial repeated. The cerebral blood flow and peripheral blood flow of the volunteers in both groups were measured by mean velocity (Vm), peak systolic velocity (Vs), pulsatility index (PI), perfusion units (PU) and mean blood pressure (BP) before the intervention (baseline), 30 minutes after the intervention, and again 60 minutes after the intervention. Results : 1. The Vm increased significantly in the moxibustion group. The Vs also constantly increased in moxibustion group, but there was no significant difference. 2. The PI decreased significantly in the control group at 0-30 minutes and in the moxibustion group at 30-60 minutes. 3. The PU constantly decreased in moxibustion group. In control group, the PU decreased at 30 minutes and increased slightly at 60 minutes. 4. The mean blood pressure did not show any significant difference between the two groups. Conclusions : This study shows that moxibustion at CV12 increased the cerebral blood flow. Based on this result, we can suggest that moxibustion at CV12 might be helpful in improving the functional recovery of stroke patients. However, further research needs to be conducted on a larger numbers of subjects in order to confirm these effects.

인체피부에서 화장품이나 화장품 원료의 안전성시험은 대체로 육안평가로 이루어져왔다. 하지만, 피부반응 초기의 미세한 변화에 대해서 육안으로는 감지하지 못하는 경우가 많다. 따라서, 본 연구에서는 수종의 화장품 원료에 의해 유발되는 홍반반응에 대해 육안평가뿐 아니라, 레이저도플러혈류이미지(LDPI) 측정장비를 이용한 혈류변화 측정, $Vapometer^{(R)}$를 이용한 경피수분손실량(TEWL) 측정, 분광광도계를 이용한 피부색 측정과 같은 기기평가를 병행하여 비교하였다. 30명의 건강한 여성 피험자를 대상으로 오일류 7종, 계면활성제류 6종, 보습제류 5종을 피험자의 등 부위에24 h 폐쇄첩포(D0)하여 피부반응을 유도하였고 첩포 제거 후 30 min (D1), 24 h (D2)에 육안평가와 기기평가를 각각 실시하였다. 육안평가 결과, 프로필렌글라이콜을 제외한 모든 오일류와 보습제류는 저자극 수준의 피부반응(반응도 0+ - 2.9+)을 보인 반면, 프로필렌글라이콜과 모든 계면활성제류는 중자극에서 강자극 수준의 피부반응(반응도 3+ - 5+)을 보였다. 기기측정 결과, 육안평가에서 저자극 범주의 피부반응에 대해서 혈류량이나 피부색보다 경피수분손실량이 가장 민감하게 피부변화를 감지하였다.
