To investigate the difference of sweating reaction on somato types. We measured total sweat rate, locl sweat rate, skin temperature, physiological reactions and psyschological reactions at $25{\pm}1^{\circ}C$ and $25{\pm}1^{\circ}C$ under laboratory conditions. Nine healthy adult females were divided into three somato types (slender(3), normal(3) and obese type(3)). The results were as follows; Total sweat rate was highest in obese type, and then comes normal type and slender type in order. Local sweat rate was highest in infrascapular area, and then breast, the back of the hand, upperarm, ant. leg, and ant. thigh in order in all somato types. Mean skin temperature was highest in slender type, and then normal type and obese type in order. Rectal temperature, blood pressure and pulse rate were highest in boese type. Psychological reactions were appeared 'hot' 'humid' 'sweat' as ambient temperature go up. And somato types make little difference in psychological reactions.

To investigate the difference of sweating reaction by the somato types, we measured total sweat rate, local sweat rate, skin temperature, physiological reaction and psychological reaction at $25{\pm}1^{\circ}C$ and $29{\pm}1^{\circ}C$ under laboratory conditons. Nine healthy adult females were divided into three somato types : slender (3), normal (3) and obese (3). The results were as follows ; Total sweat rate was highest in the obese type, followed by the normal and slender types in order. Local sweat rate was highest in the infrascapular area, and then came breast, the back of the hand, upper ann, anterior leg, and anterior thigh in all somato types. Mean skin temperature was highest in the slender type, and followed the normal and obese types. Rectal temperature, blood pressure and pulse rate were highest in the obese type. Psychological reaction appeared 'hot', 'humid', 'sweaty' as ambient temperature went up. Somato types made little difference in psychological reaction.

Objectives : The purpose of this study is to identify the effect of tonifying or sedative manipulation on LI4 and KI7 for sweet deficiency under cold environment. Methods : The participants were divided into 4 groups; intact group without acupuncture(Intact), acupuncture group inserting straightly with LI4 & KI7 method((LI4-straight KI7-straight), acupuncture group inserting twisting with LI4 tonificaton & KI7 tonificaton method(LI4-tonify KI7-tonify) and acupuncture group inserting twisting with LI4 sedation & KI7 sedation method(LI4-purge KI7-purge). We obtained the baseline data under cold condition with the temperature $14{\pm}1^{\circ}C$. After making the participant staying under cold condition for 10 minute, we measured sweating rate on skin surface and biological responses such as body temperature, oxygen saturation, pulse rate, systolic blood pressure, diastolic blood pressure, deoxy-Hb and oxy-Hb in subcutaneous. Results : The sweating rate on skin surface was not different in all treatment groups compared to the intact group. The body temperature was significantly increased in LI4-straight KI7-straight group compared to the intact group. The oxygen saturation significantly increased in LI4-purge KI7-purge group compared to the intact group. The systolic blood pressure was significantly increased in LI4-purge KI7-purge group compared to the intact group. The deoxy-Hb was significantly decreased in LI4-purge KI7-purge group compared to the intact group. Conclusions : The above results, the effect of LI4, KI7 acupuncture due to the tonifying or sedative manipulation on sweating control could be observed. However, other biological responses with the acupuncture of tonifying or sedative manipulation were giving different expressions. We suggest that continued research of tonifying or sedative manipulation is of importance order to find these expressions.

Although variable surgical methods of sympathetic nerve for palmar hyperhidrosis are curative and safe therapeutic options, they have some limitations such as compensatory sweating and anhidrosis of hand in long term satisfaction rate. Material and Method: Therefore, we tried to decrease severity of compensatory sweating and prevent excessive dryness of hand through selective division of rami communicantes of thoracic sympathetic ganglia distributed to the hands(ramicotomy). Result: In postoperative results, about half of the patients maintained humidity of hands and most of them showed no more than mild degree of compensatory sweating. Conclusion: Therefore, ramicotomy of thoracic sympathetic ganglia can be recommended as selective and physiologic surgical method for palmar hyperhidrosis.

Compensatory sweating is the main cause of patient dissatisfaction after sympathetic surgery for craniofacial hyperhidrosis. Surgery that sympathetic nerve trunk preserved and extent of resection limited was introduced to decrease compensatory sweating. From Jan 2000 to July 2002, the vidio-assisted thoracoscopic T2 sympathetic clipping and rami comunicantes selective division were performed in 36 patients suffering from craniofacial hyperhidrosis. Twenty two patients underwent a T2 sympathetic nerve clipping (Group 1), and fourteen patients underwent division of the T2 ramicommunicates (Group 2). We retrospectively analysed the rate of satisfaction, dryness of face, the rate of compensatory sweating, grade of compensatory sweating. The dryness of face was that no statistical difference between group 1 and group 2 (p=0.387); group1: dry 22.7% (5/22), humid 77.3% (17/22) group 2: dry 14.3% (2/14), humid 78.5% (11/14), persist 7.2% (1/14). The rate of satisfaction was 77.3% in T2 clipping and 64.2% in T2 sympathicotomy with no significant in the statistic analysis (p=0.396). The rate of compensatory sweating on group 2 was lower than group 1 (p=0.042); 95.4% (21/22) in T1 sympathetic clipping and 71.4% in T2 ramicotomy. The rate of embarrassing and disabling compensatory sweating was 70.5% (embarassing 8 patients, disabling 9 patients) in T2 clipping and 42.9% (embarassing 8 patients, disabling 9 patients)in T2 ramicotomy with statistically significant difference (p=0.036). The sympathetic trunk preservation surgery for craniofacial hyperhidrosis (T2 ramicotomy) redueced the rate of compensatory sweating when compared to the blocking surgery of sypathetic trunk (T2 clipping).

Tropical inhabitants are able to tolerate heat through permanent residence in hot and often humid tropical climates. The goal of this study was to clarify the peripheral mechanisms involved in thermal sweating pre and post exposure (heat-acclimatization over 10 days) by studying the sweating responses to acetylcholine (ACh), a primary neurotransmitter of sudomotor activity, in healthy subjects (n=12). Ten percent ACh was administered on the inner forearm skin for iontophoresis. Quantitative sudomotor axon reflex testing, after iontophoresis (2 mA for 5 min) with ACH, was performed to determine directly activated (DIR) and axon reflex-mediated (AXR) sweating during ACh iontophoresis. The sweat rate, activated sweat gland density, sweat gland output per single gland activated, as well as oral and skin temperature changes were measured. The post exposure activity had a short onset time (p<0.01), higher active sweat rate [(AXR (p<0.001) and DIR (p<0.001)], higher sweat output per gland (p<0.001) and higher transepidermal water loss (p<0.001) compared to the pre-exposure measurements. The activated sweat rate in the sudomotor activity increased the output for post-exposure compared to the pre-exposure measurements. The results suggested that post-exposure activity showed a higher active sweat gland output due to the combination of a higher AXR (DIR) sweat rate and a shorter onset time. Therefore, higher sudomotor responses to ACh receptors indicate accelerated sympathetic nerve responsiveness to ACh sensitivity by exposure to environmental conditions.

Background: Video-assisted sympathicotomy is a safe and effective method for the treatment of essential hyperhidrosis with immediate symptomatic improvement. However, this is offset by the occurrence of a high rate of side-effects, such as embarrassing compensatory hyperhidrosis. Therefore, by comparing and assessing the relationship between temperature change measured by DITI (digital infrared thermographic imaging) and clinical results according to the level and extent of sympathicotomy in essential hyperhidrosis. we tried to obtain a more precisely and objectively, the distribution and degree of compensatory sweating by DITI and also for ascertaining the clinical usefulness. Material and Method: From January 2000 to June 2002, the thoracoscopic sympathicotomy was performed in 28 patients suffering from essential hyperhidrosis in Dept. of Thoracic and Cardiovascular Surgery, Wonkwang University Hospital. The patients were divided into four groups, Group I: patients having undergone T2 sympathicotomy, Group II: patients having undergone T3 sympathicotomy, Group III: patients having undergone T3,4 sympathicotomy, and Group IV: patients having undergone T2,3,4 sympathicotomy. The parameters were composed of the satisfaction rate of treatment, the degree of compensatory and plantar sweating, and temperature changes of entire body measured by DITI Result: There was no difference in age and follow-up period among the groups. All of the treated patients obtained satisfactory alleviation of essential hyperhidrosis in immediate postoperative period. However, the rate of long-term satisfaction were 85.8%, 85.8%, 42.9%, and 28.6% in group I, II, III, and IV (p<0.05). More than embarrassing compensatory sweating was present in 14.2%, 14.2%, 57.1%, 71.4% in group I, II, III, and IV (p<0.05) In regard to plantar sweating, decrease in sweating was expressed in each of four groups, but was not significant between groups. An apparent increase of temperature measured by DITI indicated sufficient denervation and predicted long-lasting relief of essential hyperhidrosis and also decrease in temperature of trunk and lower extremity by DITI had correlated well with postoperative satisfaction, and also postoperative compensatory sweating. Conclusion: We suggested that the incidence and degree of compensatory sweating was closely related to the site and the extent of thoracic sympathicotomy. Resection of the lower interganglionic neural fiber of the second thoracic sympathetic ganglion on the third rib is the most practical and minimally invasive treatment than other surgical methods. We were also to anticipated the distribution and degree of compensatory sweating by DITI precisely and objectively and for ascertaining the clinical usefulness.

Background: Video-assisted thoracoscopic sympathicotomy has been determined to be the best way to treat palmar hyperhidrosis. However, satisfaction with the surgical outcomes decreases with the onset of compensatory hyperhidrosis (CH) over time. The ideal level of sympathicotomy is controversial. Therefore, we compared the long-term results of R3 and R4 sympathicotomy. Methods: We retrospectively reviewed 186 patients who underwent video-assisted thoracoscopic sympathicotomy between September 2001 and September 2015. We analyzed the long-term results with respect to hand sweating and CH, and the overall satisfaction in 186 patients. Results: With respect to hand sweating, significantly more patients complained of overly dry hands in the R3 group (25% versus 3.7%, p<0.001) and of mildly wet hands in the R4 group (2.9% versus 13.4%, p=0.007). There was a significantly increased occurrence rate of CH in the R3 group (97.1% versus 65.9%, p< 0.001). The most frequent site of CH was the trunk area. The overall satisfaction was higher in the R4 group, but without significance (75% versus 85.4%, p=0.082). Significantly more patients reported being very satisfied in the R4 group (5.8% versus 22.0%, p=0.001). Conclusion: T he R4 group had a higher rate of satisfaction than the R3 group with respect to hand sweating. CH and hand dryness were significantly less common in the R4 group than in the R3 group. The lower occurrence of hand dryness and CH resulted in a higher satisfaction rate in the R4 group.

We investigated the sweating response during passive heating (partial submersion up to the umbilical line in $42{\pm}0.5^{\circ}C$ water, 30 min) after summer and winter seasonal acclimatization (SA). Testing was performed in July during the summer, 2011 [summer-SA; temp, $25.6{\pm}1.8^{\circ}C;$ relative humidity (RH), $82.1{\pm}8.2%$] and in January during the winter, 2012 (winter-SA; temp, $-2.7{\pm}2.9^{\circ};$ RH, $65.0{\pm}13.1%$) in Cheonan ($126^{\circ}52^{\prime}N$, 33.38'E), Republic of Korea. All experiments were carried out in an automated climatic chamber (temp, $25.0{\pm}0.5^{\circ}C$: RH, $60.0{\pm}3.0%$). Fifteen healthy men (age, $23.4{\pm}2.5$ years; height, $175.0{\pm}5.9cm;$ weight, $65.3{\pm}6.1kg$) participated in the study. Local sweat onset time was delayed during winter-SA compared to that after summer-SA (p<0.001). Local sweat volume, whole body sweat volume, and evaporative loss volume decreased significantly after winter-SA compared to those after summer-SA (p<0.001). Changes in basal metabolic rate increased significantly after winter-SA (p<0.001), and tympanic temperature and mean body temperature were significantly lower after summer-SA (p<0.05). In conclusion, central sudomotor acitivity becomes sensitive to summer-SA and blunt to winter-SA in Rebubic of Korea. These results suggest that the body adjusts its temperature by economically controlling the sweating rate but does not lower the thermal dissipation rate through a more effective evaporation scheme after summer-SA than that after winter-SA.

Background: Thoracoscopic R3 sympathicotomy can effectively treat palmar hyperhidrosis. Here, we evaluated post-operative outcomes of patients receiving a thoracoscopic R3 sympathicotomy due to palmar hyperhidrosis. Material and Method: From January 2001 to December 2006, 225 patients were treated with a R3 sympathicotomy, and follow up was completed for 200 patients, with an average follow up period of 51.7 ($11{\sim}80$) months. We measured postoperative hand sweating according to four grades; dry (grade 1), proper (grade 2), light sweating (grade 3), heavy sweating (grade 4) and evaluated patient satisfaction using 4 grades: very good (grade 0), good (grade1), regular (grade 2), and deficient (grade 3). Result: There were no differences in clinical parameters between the compensatory sweating group and the non-compensatory sweating group. There was a 83.5% compensatory sweating rate. The degree of compensatory sweating related to the patient's body mass index and was influenced by the season, environmental temperature, and emotional stress. Conclusion: The satisfaction rate was 61.5%, and the degree of satisfaction related to the development of compensatory sweating. Therefore, reducing compensatory sweating would increase patient satisfaction with R3 sympathicotomies.
