People in tropics have the ability to tolerate heat by residential permanence in the tropics. Previously, we have shown that African and Thai subjects who lived for whole their lives in only their respective countries sweat less under hot conditions than South Koreans who also lived whole their lives in Korea. The difference in sweating responses was attributed to the dissimilar central and peripheral sweating mechanisms operating in people from both groups. In the present study, acetylcholine (ACh), the primary transmitter for the sudomotor functions, was iontophoretically administered to South Koreans and Africans to determine the characteristic sudorific responses of their acclimatized biologic make-up to their respective environments. Using quantitative sudomotor axon reflex test (QSART), direct (DIR) and axon reflex (AXR) responses were evaluated. The findings revealed that the sweat onset-time among South Koreans was 0.91 min earlier than among Africans (P<0.01). The axon reflex sweat volume of nicotine receptor activity AXR(1) and sweat volume of muscarinic receptor activity DIR(2) among South Koreans were 79% and 53% greater (P<0.01), respectively. These results indicate that the reduced thermal sweating among Africans is at least in part attributed to the diminished sensitivity of sweat glands to ACh.

Tropical natives (TROP) are capable of tolerating tropical heat because of their long-term adaptation to tropical environments. When exposed to heat stress, these natives tend to respond with lower sweat output, which is generally thought to be the result of heat acclimatization. The main objective of this study was to clarify central mechanisms inherent to suppressed thermal sweating in tropical natives (Malaysians) by comparing their sweating responses to those of temperate native (TEMP) (Koreans). This experiment was conducted in a thermoneutral climatic chamber ($24{\pm}0.5^{\circ}C,\;40{\pm}3%$ relative humidity). Heat loads were applied to each subject by the immersion of their lower legs in a hot water bath ($43^{\circ}C$ for 30 min). Sweat onset-time and sweat volume were compared between TROP and TEMP. The sweat onset-times on four selected points on the body ranged from 10.25 to 13.47 min in TEMP subjects, and from 16.24 to 17.83 min in TROP subjects (p<0.001). The local sweat volumes at the same sites ranged from 4.30 to $9.74 mg/cm^2$ in TEMP subjects, and from between 1.80 to $4.40mg/cm^2$ in TROP subjects (p<0.001). These results demonstrated a significant difference between TROP and TEMP subjects with regard to the manner in which they regulate their body temperatures when exposed to heat loads, and verified that long-term thermal adaptation blunts sweating sensitivities.

배경: 비디오흉강경에 의한 교감신경차단술은 본태성 다한증환자에서 수술 즉시 증세의 호전을 보이는 안전하고 효과적인 방법이다. 하지만 이것은 곤혹스러운 보상성발한과 같은 높은 빈도의 부작용 발생으로 상쇄된다. 그래서 본태성다한증에서 교감신경차단술의 차단범위와 부위에 따른 임상결과와 컴퓨터 적외선 체열 영상에 의해 측정한 온도 사이의 관계를 비교하고 평가하였다. 컴퓨터 적외선 체열 영상에 의해서 보상성발한의 정도와 분포를 더 객관적으로 그리고 정확하게 예기할 수 있는가, 또한 임상적 유용성을 확인하기 위해서 시행하였다. 대상 및 방법: 2000년 1월부터 2002년 6월까지 원광대병원 흉부외과학교실에서 다한증을 갖고 있는 28명의 환자에서 흉강경에 의한 흉부 교감신경차단술을 시행하였다. 환자는 각각 7명 인 4군으로 분리하였는데 I군은 제2번 T2 교감신경차단술, II군은 T3 교감신경차단술, III군은 T3,4 교감신경차단술 그리고 IV군은 T2,3,4 교감신경차단술을 시행하였다. 변수는 치료의 만족도, 보상성발한의 빈도, 족부 발한의 정도 그리고 DITI에 의해 측정한 전신의 체열 변화로 구성하였다. 결과: 나이와 추적기간에는 차이가 없었다. 모든 치료한 환자에서 수술 즉시는 만족할 만한 완화를 얻었다. 하지만 만기 시의 만족도는 I, II, III, IV군에서 각각 85.8%, 85.8%, 42.9%, 그리고 28.6%를 보였다. 곤혹스러울 정도 이상의 보상성발한은 I, II, III, IV군에서 각각 14.2%, 14.2%, 57.2%, 그리고 71.4%를 보였다. 족부 발한에서는 다소 호전을 보였으나 각 군 사이에 의미는 없었다. DITI에 의해 측정한 체열의 명백한 상승은 충분한 탈 신경을 암시하고 본태성다한증의 지속적인 완화를 예기할 수 있으며 체간부와 하지의 체열하강은 수술후의 만족도와 보상성발한과 일치하였다. 결론: 보상성발한의 정도와 빈도는 흉부 교감신경차단술의 범위와 부위에 밀접하게 연관된다. 제3번째 늑골상단에서 제2번 교감신경절의 하신경절 간 신경섬유의 차단이 다른 수술방법보다 실질적이고 최소 침습적 치료이다. 또한 DITI에 의해서도 보상성발한의 분포와 정도를 확실하게 그리고 객관적으로 예기할 수 있으며 임상적 유용성을 확인할 수 있었다.

1. Backgrounds: There are a lack of comprehensive study on Taeeumin Exterior Heat syndrome diarrhea(表熱證泄瀉). Thus, The author examines the content of various literatures related to Tae-eumin Exterior Heat syndrome diarrhea. 2. Methods: Literature examination is used Lee, Je-ma's writings and Sasang Constitutional Medical doctor's writings. Syndrome examination is used Tae-eumin's study on Syndrome of DonguisusebowonGaboGu-bon("咸山沙村東醫壽世保元甲午舊本") and Donguisusebowon("東醫壽世保元") and treatises of the academic world. 3. Results: and Conclusions: 1) "Profuse sweating and reddish and difficult urination"(汗多而小便赤澁) is regard as Taeeumin Interior Febrile Disease(裏熱病). 2) There is no possibility of a misprint about Taeeumin Exterior Heat syndrome diarrhea. Taeeumin Exterior Heat syndrome diarrhea is engaged in both the Exterior and Interior(表裏俱病). 3) It is difficult to prescribe GalgeunHaegi-Tang(葛根解肌湯) instead of Galgeunnabokja-Tang(葛根蘿葍子湯). 4) Tae-eumin Exterior Heat syndrome diarrhea is formed in the early period and absorbed into Donguisusebowon ("東醫壽世保元") in the latter period. "Profuse sweating and reddish and difficult urination" is estimated to be added in the latter period.

This study was investigated to evaluate the physiological responses on T-shirts manufactured with selected functional materials by body parts which were selectioned on the distribution of sweating and temperature change. Seven healthy men in twenties were participated in a climate chamber of $27{\pm}0.5^{\circ}C$ and $50{\pm}1%RHC$. Three kinds of T-shirts named 'D1', 'D2' and 'Poly' were used as experimental clothings. Four kinds of functional materials of quick absorbing/drying were used in all section in 'D1', but two kinds of functional materials used partially in 'D2'. 'Poly' T-shirts used only polyester. In an experimental schedule of 90 minutes, which were consisted of 'Rest', twice of 'Exercise' and twice of 'Recovery' periods, the subjects walked on a treadmill with 60% of $VO_2max$. As a physiological responses, the microclimate temperature, surface temperature(skin, clothing) and sweat rate were measured. Temperature regulation was kept well in 'D1' rather than other T-shirts. The quick absorbing/drying T-shirts showed its performance well as the exercise goes on the second half. With these results in mind, 'D1' will be more effective for long hours exercise such as climbing rather than short hours exercise.

This study evaluated the wear comfort properties of water-vapor-permeable (WVP) garments using a movable sweating thermal manikin. Manikin tests were performed in a climatic chamber (temperature T=20, $35{\pm}0.5^{\circ}C$ and relative humidity $H=50{\pm}10%$) using seven sportswear outfits (a long sleeve shirts and a long pants) made with seven different WVP fabrics. Physiological responses of wear trials could be correlated with measurement parameters of the thermal manikin experiment; subsequently, a regression model that represented a final comfort sensation could be obtained. The regression model developed in this work is based on thermal manikin measurements; consequently, it provides an independent comfort sensation level in a relatively short time at a low cost while maintaining the reproducibility of results. It translates into more actual choices for sportswear manufacturers and sportswear consumers.

This study was designed to investigate the expression and production of interleukin-1beta $(IL-1{\beta})$ in human peripheral blood of trained runners and untrained controls after temporary moderate intensity exercise. Male long-distance trained runners (TR) and untrained sedentary control subjects (SED) ran for 1 h at 70% of heart rate reserve (HRR). $IL-1{\beta}$ gene and protein expressions were significantly higher in TR than those with SED at all 3 intervals examined independently. Significant increases in total sweat volume and oral temperature were observed after exercise in both groups, however, there were some differences between the groups. We conclude, therefore, that sweating due to exercise is associated with increase of $IL-1{\beta}$ and it is correlated with decrease of oral temperature.

Objective: The case study assessed the possibility of improving symptoms by external treatment in a patient complaining of night sweats who could not take oral herbal medicine. Methods: Chinensis galla, Ostreae concha, and Cinnabaris were mixed in a 2:1:1 ratio and applied to CV8 before the patient went to bed. The treatment was removed upon waking and repeated every night. If itchiness and skin redness occurred, the position was changed to 2-3 cm up or down from the navel or application was changed to once every two days. Results: The external treatment eliminated the symptoms of sweating in the arms, legs, chest, and abdomen and reduced sweating in the occipital and neck areas. The sweating was improved to the extent that it no longer interfered with daily life. Conclusions: This case study shows the possibility of using external treatments rather than herbal medicine to treat night sweats.

We report on a Soeumin patient with spontaneous sweating after a lung segmentectomy resulting from aspergillosis. During her inpatient stay, the patient received Soeumin Gwakhyangjunggi-san, Hwanggigyeji-tang, and Seungyangikgi-tang for herbal medication. She also received acupuncture, moxibustion, pharmacopuncture, and cupping therapy. A numeric rating scale (NRS) was used to assess the improvement of symptoms. Sweating was reduced, as reflected by an NRS change from 7 to 0, when the herbal medication changed from Soeumin Gwakhyangjunggi-san to Hwanggigyeji-tang. General weakness and chest discomfort were also relieved after using Hwanggigyeji-tang and Seungyangikgi-tang. These results suggest that Hwanggigyeji-tang and Seungyangikgi-tang are clinically effective for Soeumin patients who are appropriately diagnosed with yang collapse syndrome in the postoperative setting.
