The word of stress was wsed in the field of physics as a external force from 17th century, but the meaning of this stress had chafed to the internal and exteral demand fort the human body in medical area. All the stumulants which make stress was called as j stressor. When animals get stress blucose excreted from liver to adapt for the emergent state ant some related hormone secrete convert protein and lipid to glucose for the purpose of energy supply to muscle. As a results heart rate, blood pressure, respiration rate are increased and musclse are strengthed. These physiolgical reactions ate controlled by autonomic nerve system under the control of hyothalamus in brain. Autonomic nerve system and endocrinary system are react harmoiously to stress reaction. According to the stress reaction, adrenomedullary system are stimulated, and epinephrine, morepinephrine are exceted. Author experimented the effect of the immobilizational stress to rat by analyzing the variaition of catecholamine secrction, the Na concentration and the effect of the antistresf effect by Panax Ginseng which is a traditional Korean herb medicine. The concentration of the norepinephrine, epinephrin, and dopamin in normal rat are 1 578 ng/ml, 0.365 ng/ml, and 0.731 ng/ml respectively, but in the immobilyzed stress groIn the concentration were increased to 1.915 ng.ml, 0.854 ng/ml, and 2,361 ng/ml which she the high show the higher concentration of catecholamine to stressor.

선천성 고혈압 흰쥐(SHR)와 정상혈압 흰쥐에서 교감신경성 신경전달에 미치는 부신수질 및 renin-angiotensin계의 역할을 알아보기 위해, 부신수질을 제거하거나 angiotensin 변환 효소 억제제를 장기간 처치한 뒤 중추신경계가 파괴된 상태에서 절전신경을 자극했을 때 나타나는 승압반응과 대동맥의 catecholamine농도 및 angiotensin 변환 효소 활성도의 변화를 비교 검토하였다. 부신수질을 제거하더라도 중추신경계를 파괴하기 전후의 혈압에는 영향을 주지 못했으며, 절전 신경 자극에 의한 승압반응은, 자극 주파수에 의존적으로 증가하였으며 prazosin 전처치로서 거의 완전히 억제되었다. 정상혈압 흰쥐에서와는 달리, 선천성 고혈압 흰쥐에서는 부신수질을 제거했을 때는 절전신경 자극에 의한 승압반응이 부신수질을 제거하지 않는 군(이하 대조군)에 비하여 유의하게 약화되었다. SHR에서 부신수질 제거로 부신 catecholamine 함량은 현저히 감소되었고, 혈청의 angiotensin 변환 효소 활성도는 감소되는 경향을 나타내었다. 그러나 혈장 및 대동맥 절편의 catecholamine 함량, 대동맥 절편의 angiotensin 변환 효소의 활성도는 대조군과 유의한 차이가 없었다. 그러나 WKY에서는 부신수질이 제거된 군에서 대동맥 절편의 angiotensin 변환 효소의 활성도와 catecholamine함량이 대조군에 비해 유의하게 증가되어 있었다. Enalapril처치에 의해서 선천성 고혈압 흰쥐 평균 혈압은, 부신 catecholamine 함량 및 대동맥 절편의 angiotensin 변화 효소의 활성도와 함께 현저히 저하되어 정상혈압 흰쥐와 유사하였다. 그리고 선천성 고혈압 흰쥐에서 부신수질의 제거로 절전신경 자극에 의한 승압반응이 대조군에 비하여 약화되는 현상은 enalapril을 처치하였을 때는 관찰되지 않았다. 이상의 결과로 미루어보아 교감신경성 신경전달을 항진시키는 부신수질의 작용은 renin-angiotensin계의 활성화에 의존적이었으며, 부신수질의 제거로 정상혈압 흰쥐에서는 renin-angiotensin계가 보상적인 조절이 일어났으나, 선천성 고혈압 흰쥐에서는 보상적인 조절이 일어나지 않았다.

The term of stress was used by many scientists, but there were several difinitions about stress, and this term are using in societies frequently. Generally stress is defined as equilibrium, harmony, and adaptation to external stimulations, in 1930 s Hans Selye was the first scientist who used the term of stress and he pointed out the stress mean the function of force in body. When we get stress the stimulation go to the sympathetic-adrenomedulla system and epinephrine and norepinnephrine are secreted from adrenal medulla. Author tried to investigate the change of catecholamine secretion from rat urine which were exposed to 80 dB noise environment. The control rat urine released 0.03 $\pm$ 0.01 ng/ml of epinephrine and 0.18 $\pm$ 0.04 ng/ml, but in noise exposed group the epinephrine was 0.42 $\pm$ 0.07 ng/ml and norepinephrine was 2.16 $\pm$ 0.48 ng/ml.

Noise is not only affecting the ear and the auditory cortex locally, but its influence is widely spread throughout the brain structures, e. g., the reticular formation, the brain stem nuclei or the subcortical forebrain area. Hence, any of the organism's activities can be hindered or stimulated by noise. High noise is a stressor and the catecholamine level can be used both as a stress marker and as an indicator of modified sympathetic nervous system activity. Several recent studies have found that the urinary excretion of catecholamines is increased due to high noise intensity, especially unexpectedly high and long lasting noise. The present study was conducted in order to examine the effects of noise stress on urinary excretion of ctecholamines in rats and humans. Rats were exposed to 90 dB noise for 10, 30, and 60 minutes, 3 and 12 hours. 24 hour . urinary samples were collected and the catecholamones were extracted by alumina and analyzed by HPLC-ECD. Catecholamine levels increased with time of exposure up to 60 minutes : norepinephrine concentration at 60 min of noise=1.038 ng/ml, epinephrine=0.636 ng/ml. Urine catecholamines of blue collar workers exposed to 90 dB of noise at the work place were collected between 2 and 4 p.m. and compared to that of white collar workers exposed to 70 dB. Mean norepinephrine level of the blue collar workers was 0.89 ng/ml (${\pm}0.25$), epinephrine 0.24ng/m1 (${\pm}0.09$), and that of the white collar workers 0.48 ng/ml (${\pm}0.12$), epinephrine 0.19 ng/ml(${\pm}0.05$). It was concluded that noise acts as a stressor and increases the catecholamine levels in both rats and humans.

This study was designed to evaluate the effect of the bee venom(BV) aqua-acupuncture on the neuronal activities of catecholaminergic(tyrosine hydroxylase : TH, dopamine ${\beta}$ hydroxylase : D${\beta}$H) system in the brainstem. After the BV aqua-acupuncture was applied on Chok-Samni(ST36) and the gluteal part(Blank locus) in rats. Also, the number of colocalization between catecholamine containing neurons and Fos immunoreactive neurons were analyzed by using the double immunohistochemical technique. The results of the experiments were summarized as follows : 1. In DR and LC, Chok-Samni group and the Blank locus group showed more significant increase in the number of colocalization between TH containing neurons and Fos immunoreactive neurons than the control group. Furthermore, Chok-Samni group showed more significant increase than the Blank locus group. Also, in Arc, Chok-Samni group showed more significant increase than the Blank locus group and the control group. 2. In LC, Chok-Samni group showed more significant increase in the number of colocalization between D${\beta}$H containing neurons and Fos immunoreactive neurons than the Blank locus group and the control group. Also, in A5, Chok-Samni group and the Blank locus group showed more significant increase than the control group. Chok-Samni group showed more significant increase than the Blank locus group. However, there was no significant change in A7. Consequently, the BV aqua-acupuncture increased more potent the number of Fos immunoreactive neurons and the activity of catecholaminergic neurons. Furthermore, the BV aqua-acupuncture was more effective on Chok-Samni than Blank locus group. These results indicate that the BV aqua-acupuncture is very effective therapy to control pain. The therapeutic effect of BV aqua-acupunture may associated with the endogenous modulatory system such as catecholamine. Those data from the study can be applied to establish the effective treatment of the BV for pain control in the clinical field.

A question whether abnormal responsiveness of hypothalamic catecholaminergic nervous system to ovarian steoid hormones in spontaneously hypertensive rats (SHR) exist was investigated. Four groups of experimental animals were prepared for SHR and normotensive Wistar rats (NW) respectively: 1) intact, 2) ovariectomized (OVX+V), 3) ovariectomized and estrogen treated (OVX+E), 4) ovariectomized and estrogen plus progesterone treated (OVX+E+P) groups. Hypothalami from experimental animals were dissected out and used for determination of .alpha.-adrenergic receptor binding characteristics and catecholamine contents. Norepinephrine(NE) content and B$_{max}$ of $\alpha_1$-adrenergic receptors in hypothalami were greater in intact SHR than in intact NW, but dopamine(DA) content was lower in SHR than in NW. Neither contents of NE and DA nor binding characteristics of $\alpha_1$-adrenergic receptors were different in OVX+V and OVX+E group from intact group of both SHR and NW. Kd and B$_{max}$ of $\alpha_1$-adrenergic receptors in OVX+E+P was lower than that in intact SHR but not in NW. DA content was lower in OVX+E+P than in intact group of SHR and NW. The result of the present study indicates that there is an abnormal responsiveness of hypothalamic catecholaminergic nervous system to ovarian steroid hormones in SHR which may be one of genetically-determined factors probably not responsible for the development of hypertension.

This study was performed to investigate the effects of Qigong training after physical training stress in untrained college students For this study, 6 voluntary subjects(male 4, female 2) were chosen in untrained students of K University. they were trained by teachers during 6 weeks and tested just before Qingong training and after 6 weeks. Each subject was performed a treadmill exercise(model Q65, Quinton Co, U.S.A.) to the all-out state. During exercise stress test, electrocardiogram, heart rate were checked by stress test monitor(model Q4500, Quinton Co, U.S.A) and also oxygen uptake, maximal oxygen uptake analyzed continuously by automatic gas analysis(model QMC, Quinton Co, U.S.A). During physical training the serum were collected 3 times, pre-experimental rest time, and serum catecholamine were measured by HPLC.T-test of statistical analysis system was used in every experiment for statistical assessment. The results of T-test on these data were summarized as follow:1.Heart rate change during exercise stress test after Qigong training was shown more decreasing tendency than before training. Especially, heart rate change after Qigong training during resting periods was decreased significantly than before training.2. Oxygen uptake change during exercise stress test after Qigong training was shown more increasing tendency than before training, And also maximal oxygen uptake after Qigong training was shown more increasing tendency than before 6 weeks.3. Epinephrine level of after Qigong training was more decreased significantly than before training in all-out state. And norepinephrine level of after Qigong training was shown more decreasing tendency than before training in all-out state and after 30 minutes rest time. Above results indicate that Qigong training for 6 weeks could be effective to elevate the cardiopulmonary functions and diminish the stress responses of the physical stress.

Purpose: Anxiety and depression are the concepts that commonly used as an emotional approach in the nursing researches and most of researches have been used questionnaires as a marker of anxiety and depression. There were few researches using physiological markers in measuring anxiety and depression. Methods: Journals published between 1950 and 2007 that include depression and anxiety measuring through physiological markers were reviewed. Results: As in the case of the hypothlamus-pituitary-adrenal axis system, it appeared that cortisol, epinephrine, and norepinephrine belonged to the category of hormones which were responsive to anxiety and depression. Plasma norepinephrine was a marker of the anxiety whereas plasma cortisol was a marker of the depression. The anxiety and depression were correlated with immune and taste, but it considered as an outcome variable not a physiological marker. Conclusion: Catecholamine and cortisol reflect anxiety and depression state. Our findings suggest that further researches are needed to distinguish between markers and outcomes of depression and anxiety using physiological markers.
