배경: 독일 크나이프 요법을 국내에서 적용하기 위해 검증 연구가 필요하다. 목적: 국내 산림 환경에서 적용한 크나이프 요법이 자율 신경계 및 회복탄력성에 미치는 영향을 규명하기 위함이다. 방법: 크나이프 요법 중 4가지 요소('움직임', '삶의 질서', '음식 섭취', '치유 식물')를 고려한 중재 프로그램을 구성하여, 성인 40명을 대상으로 적용했다. 중재 전과 후에 맥파측정기(uBioMacpa)를 이용하여 HRV(TP, VLF, LF, HF, LF/HF, CSI: Cumulative Stress Index)와 회복탄력성 지수를 측정하고 비교 분석했다. 결과: HRV를 분석한 결과, 프로그램 중재 후 연구 대상자의 TP(8.64%, p<.001), VLF(6.96%, p<.05), LF(15.86%, p<.001), HF(8.46%, p<.01), LF/HF(5.77%, p<.05)는 유의하게 증가하였고, CSI는 유의하게 감소하였다(16.06% p<.001). KRQ-53 평균 점수는 191.56점에서 206.22점으로 14.66점 증가한 것으로 나타났다. 결론: 국내 산림 환경에서 적용한 크나이프 요법은 자율신경계를 전체적으로 활성화하고, 교감과 부교감신경의 활성도를 높여 심장 활동을 촉진시키며, 누적 스트레스를 감소시켜 주었다. 그리고 회복탄력성을 개선하는 것으로 나타났으며(p<.05), 특히 자기 조절 능력 요인에서 그 효과가 큰 것으로 확인되었다. 본 연구의 결과는 크나이프 요법이 국내 산림 환경에서 치유 프로그램으로 활용되어 스트레스 해소를 포함한 자율 신경계의 긍정적인 효과를 제시한 초기적인 최초의 증거라 할 수 있다.

The purpose of this study was to examine the influence of the exercise performance of yoga and pilates on the autonomic nervous system in an effort to provide some clinical information on exercise prescription. The subjects were 20 selected college students who majored in P.E. A yoga group and a pilates group were organized with 10 students respectively, the autonomic nervous system of the students was measured before the exercise, immediately after that and 30 minutes after recovery. The findings of the study were as follows: First, there were significant differences in the yoga group's stress index and average pulse according to the main effect of the time and interaction effect between the time and group. Second, there were significant differences in the yoga group's sympathetic nervous system activity and autonomic nerve balance according to all the main effect of the time, interaction effect between the time and group and the main effect of group. Third, there were significant differences in HRV(Heart Rate Variability), parasympathetic nervous system activity, SDNN, and RMSSD according to the main effect of the time, and interaction effect between the time and group and the main effect of group produced no statistically significant differences. In conclusion, yoga seemed to be effective at lowering stress index and average pulse. Specifically, yoga exercise seemed to exert a more positive influence on the decrease of sympathetic nervous system activity and autonomic nerve balance than pilates exercise.

The signal transduction pathway for most neurotransmitter induced inhibition of $Ca^{2+}$ channels in sympathetic neurons involves a G-protein mediated, membrane-delimited mechanism without the participation of any known protein kinase. However, activation of protein kinase C (PKC) has been proposed as one of the intracellular mechanisms mediating some neurotransmitter induced $Ca^{2+}$ channel inhibition. In the present study, we investigated the effects of phorbol-12, 13-dibutyrate (PDBu) on $Ca^{2+}$ channel currents of acutely dispersed neurons from adult rat superior cervical ganglion (SCG) neurons using whole cell variant of the patch clamp technique. PDBu (500 nM), the activator of PKC, increased $Ca^{2+}$ channel currents and retarded the deactivation of tail currents. The effects of PDBu were voltage dependent and the maximal increase in the current amplitudes was observed between -10 to 10 mV (n=4). PDBu attenuated $Ca^{2+}$ current inhibition induced by norepinephrine (NE), which modulates $Ca^{2+}$ channels via a pertussis toxin (PTX)-sensitive pathway. Inhibition of PDBu by staurosporine (1 $\mu$M) blocked the effects of PDBu on current amplitudes and NE-induced G-protein mediated inhibition of $Ca^{2+}$ currents. Further experiment should be done to know if G-protein or $Ca^{2+}$ channel itself is the target of PKC phosphorvlation.phosphorvlation.

A retrospective analysis was performed on the 72 cases of peripheral artery occlusive disease treated at Yonsei Medical School Yongdong Severance Hospital, from March 1, 1990, through July 31, 1992, focusing on the operative procedures, surgical results and perioperative complications. The etiologic causes of vascular obstruction were atherosclerosis in 28 cases, Buerger's disease in 31, traumatic orgin in 7, operative complications in 4, and malignancy and arteritis in one case each. Treatment modalities, actually performed include bypass graft.(27), infusion of PGE1 (23), Embolectomy (16), Sympathectomy (4) and end-to-end anastomosis (2). There were 21 satisfactory cases and 9 unsatisfactory cases of atherosclerotive occlusive disease, defining the operative outcome as“satisfactory”if the obstructive symptoms disappeared completely and “unsatisfactory”if they did not. The patients of TAO induced Buerger's disease with preoperative Foutain class III or IV were surgically converted to class 0 in 14 cases, class I in 12 and class II in 3.

Anticholinergics, which are commonly given as a pre-anesthetic medication to prevent adverse effects in canine anesthesia, can cause cardiac adverse effects. To determine the effects of atropine and glycopyrrolate on the balance of sympathetic nervous tone and parasympathetic nervous tone of the heart during ketamine anesthesia in beagle dogs, heart rate variability(HRV), duration of anesthesia and behavioral changes were evaluated. There were no significant temporal domain differences between atropine and glycopyrrolate. Concerning the frequency domain component, atropine and glycopyrrolate effects were significantly lower(P<0.05) than the control saline-treated group. However, the root mean square of the interval differences between consecutive R peaks(RMSSD) and the standard deviation of Poincare plot perpendicular to the line-of-identity(SD1) in atropine were significantly decreased(P<0.05) from the baseline value, and the low frequency/high frequency ratio(LF:HF ratio) in glycopyrrolate was significantly increased from baseline value(P<0.05). The change of SD1 agreed with that of the high frequency(HF) in the frequency domain component and also with those of respiratory rate and $SpO_2-R$. Our results prove that glycopyrrolate is more suitable as a pre-anesthetic anticholinergic in ketamine anesthesia of dogs with respect to safety and duration of action.

As an attempt to develop new functional health beverage by using medicinal herb, we investigated the effect of medicinal plant extract (MPE) on mean arterial blood pressure (MABP) and regional cerebral blood flow (rCBF) of rats. The changes of MABP and rCBF were determined by LDF methods. LDF allows for real time, noninvasive, continuous recordings of local CBF. MABP in MPE treated rats showed significant change of MPE 1.0 and 10.0 mg/kg. MPE i.v. administration showed significant increase of rCBF in a dose-dependent manner. Propranolol pretreated MABP showed significant change in the increase of MPE. rCBF of propranolol pretreated rats showed significant change from the i.v. injection concentration of 1.0 and 10.0 mg/kg. The ischemia/reperfusion induced oxidative stress may have contributed to cerebral damage in rats, and the present study provides clear evidence for the beneficial effect of MPE on ischemia induced brain injury. Also, the action mechanism in elevation effect of MPE on rCBF might be concerned with the role of $\beta$-adrenoceptor. The exact component and mechanism remains for the future study.

This study was undertaken to confirm whether or not the sympathetic nervous system takes part in the liver regeneration after partial hepatectomy. The male Sprague-Dawley rats were pretreated with I.P. injection of guanethidine 25 mg/kg: single dose (G-1); multiple doses once a day for 3 days (G-3), for 5 days (G-5), or for 6 days (G-6). The rats were subjected to partial hepatectomy $(70.4{\pm}1.99%)$ under light anesthesia of diethyl ether. 1) The systolic blood pressure of control rat was $98.0{\pm}3.9\;mmHg$ and was not affected by G-1. But after the pretreatment with G-3, G-5 or G-6, the pressure was markedly decreased by over 25 %. 2) Both of plasma norepinephrine and epinephrine levels showed the marked increases 3 hrs after the hepatectomy. However, the increases are entirely inhibited by G-1 or G-6. 3) All the liver contents of putrescine, spermidine and spermine showed the significant increases 6 hrs after the hepatectomy and were not affected by G-1 or G-6 with the exception of the inhibition of putrescine increase by only G-6. The present results suggest that the sympathetic activation appeared after partial hepatectomy seems not to play an important role in rat liver regeneration.

Purpose : Syncope appears to be common. However, the mechanism of syncope is not clear. Increased vagal activity and withdrawal of sympathetic stimulation cause hypotension, bradycardia and finally loss of consciousness. The purpose of this study was to evaluate changes of cerebral blood flow velocity, blood pressure, and heart rate during tilt test in children with vasovagal syncope. Methods : Sixty four children with a past history of syncope were evaluated. The stand up test was performed for 15 minutes after a rest at supine position for 10 minutes, followed by an $80^{\circ}$ tilt test lasting 45 minutes. If presyncope(lightheadedness, nausea, blurred vision, or sweating) or syncope occurred, the study was discontinued. 12-lead electrocardiography, echocardiography, and electroencephalography were performed. Transcranial Doppler study was performed at the middle cerebral artery with 2 MHz continuous Doppler probe in 10 children with positive tilt test. Systolic, diastolic, mean cerebral blood flow velocity, integral, and pulsatility index were measured with blood pressure, heart rate, and $O_2$ saturation. Results : The positive rate of tilt test was 31.3%(20/64). Systolic, diastolic, and mean cerebral blood flow velocity decreased significantly in absence of hypotension or bradycardia during presyncope. Time velocity integral of cerebral artery also decreased significantly. Conclusion : Decreased cerebral blood flow velocity can predict the presyncope manifestation. Impairment of autoregulation of cerebral blood flow might play an important role in the pathophysiology of vasovagal syncope.
