Helicobacter pylori 억제효과가 우수한 청목노상의 캘러스 배양을 위한 최적조건은 MS 고체배지에서 $27^{\circ}C$에서 20일간 배양하였을 때 6.4 mm의 크기로 가장 크게 자랐으며, 청목노상의 callus 형성에 미치는 생장조절제로는 NAA, 2,4-D, BA 및 kinetin 등을 2 mg/l의 농도로 첨가하여 $27^{\circ}C$에서 20일간 배양했을 때 높은 캘러스 성장률을 확인 할 수 있었고, 생장조절제의 혼합처리구가 단독처리구 보다 캘러스 형성율이 높은 것을 확인 할 수 있다. 따라서 본 연구에 사용된 청목노상 품종의 평판기내 배양을 위한 direct callogenesis의 최적 조건은 생장호르몬으로 2,4-D/NAA를 2 mg/l의 농도로 혼합 처리하여 $27^{\circ}C$에서 20일간 배양이 최적조건이었다. 청목노상 callus로부터 Helicobacter pylori 억제물질의 대량생산을 위한 방법인 biomass를 위한 bioreactor배양은 MS 액체배지에 호르몬으로 2,4-D와 BA를 각각 1 mg/l의 농도로 처리하여 20일간 배양하였을 때가 최적조건이었다. 최적조건에서 배양한 callus 추출물의 Helicobacter pylori 에 대한 억제효과는 16 mm의 clear zone으로 가장 높은 저해율을 확인할 수 있었다.

Purpose D.I.T.I. can be used to diagnose the dysmenorrhea and prove the Oriental Medical Theory and the Sasang Constitutional Medicine concerning Dysmenorrhea. According to the Sasang Constitutional Medicine, we chose 39 dysmenorrhea patients (Soeumin 26 Patients, Taeumin 13 Patients) and expremented D.I.T.I. to find difference of chilliness and fever in the upper part of body and the lower part of body. Methods We expremented 39 dysmenorrhea patients chosena expremental group from Apr 1. 2002 to May 30, 2002. We diagnosed the constitution by Q.S.C.C. and selected six acu-points CV-17, CV-12, CV-4, G-21, B-15 and B-23. To appraise difference of temperature according to constitution we compared skin temperature of front to back. Result Mean Absolute Value of ${\Delta}T$ in body (front and back) shows significant difference. Totally the temperature of front is higher than the temperature of back. the temperature of Soeumin is higher than the temperature of Taeumin in whole. Conciusion Especially the upper abdomen area(CV-17) shows high temperature in 39 dysmenorrhea patients, the lower abdomen area (CV-4) of Soeumin shows lower temperature relatively.

To develop the model for prediction of potato late blight progress, the relationship between severity index of potato late blight transformed by the logit and Gompit transformation function and cumulative severity value (CSV) processing weather data during growing period in Taegwallyeong alpine area, 1975 to 1992 were examined. When logistic model and Gompertz model were compared by determining goodness of fit for progressive degree of late blight using CSV as independent variable, the coefficients of determination were higher as 0.742 in the logistic model than 0.680 in the Gompertz model. Parameters in logistic model were composed of progressive rate and initial value of logistic model. Initial value was calculated in -3.664. The progressive rate of potato late blight was 0.137 in cv. Superior, 0.136 in cv. Irish Cobbler, and 0.070 in cv. Jopung without fungicide sprays. According to in crease of the number of spray times the progressive rate was lowered, was 0.020 in cv. Superior under the conventional program of fungicide sprays, 10 times sprays during cropping season. Equation of progressive rate, b1=0.0088 ACSV-0.033 (R2=0.976), was written by examining the relationship between the parameters of progressive rate of late blight and the average CSV (ACSV) quantifing weather information. By estimating parameters of logistic function, model able to describe the late blight progress of potato, cv. Superior was formulated in Y=4/(1+39.0·exp((0.0088 ACSV-0.033)·CSV).

Several lines of evidence indicate that adenosine $A_{2A}$ agonist disrupts spatial working memory. However, it is unclear which stages of learning and memory are affected by the stimulation of adenosine $A_{2A}$ receptor. To clarify these points, we employed CV-1808 as adenosine $A_{2A}$ agonist and investigated its effects on acquisition, consolidation, and retrieval phases of learning and memory using passive avoidance and the Morris water maze tasks. During the acquisition phase, CV-1808 (2-phenylaminoadenosine, 1 and 2 mg/kg, i.p.) decreased the latency time in passive avoidance task and the mean savings in the Morris water maze task, respectively. During the consolidation and retrieval phase tests, CV-1808 did not exhibited any effects on latency time in passive avoidance task and the mean savings in the Morris water maze task. These results suggest that CV-1808 as an adenosine $A_{2A}$ agonist impairs memory acquisition but not consolidation or retrieval.

Objectives : The aim of this study was to observe the effect of moxibustion at combined acupoints of ST36, BL21 and CV12 in rats with sex and age. Methods : This study measured small intestinal motility in rats. First, cauterize with moxa was applied 5 times to the ST36, BL21 and CV12 in rats classified by sex and age under enflurane anesthesia. And then same treatment is done to mached acupoints of ST36, BL21 and CV12. Results : In single acupoint groups, cauterizing with moxa on ST36 increased with 5, 7 weeks in female and all weeks in male. The BL21 group increased with 5, 6, 7 weeks in female, and only 5 weeks in male. The CV12 group showed increasing with 5, 6 weeks in female and only 7 weeks in male. In combined acupoints groups, the ST36+BL21 with 8 weeks in male, the ST36+CV12 with 5, 8 weeks in female and 5, 6, 8 weeks in male, the CV12+BL21 only with 5 weeks in female, the ST36+BL21+CV12 only with 5 weeks in female showed increasing, respectively. Conclusions : Although these differents according to the sex and age in rats do not have a established tendency, the results suggested that the effects of moxibustion are experimentally should be considered the sex and age of individual.

구름버섯 자실체에서 분리된 항응고성 다당류의 혈액응고 저해기작을 검토하였다. 항응고성 다당(CV-40-Va-1)은 vWF의 활성을 감소시킴으로써 혈소판응집을 억제시키는 것으로 나타났으며, 혈액응고인자중 thrombin뿐만이 아니라 내인성경로의 factor VII, IX, XI, XII의 활성 또한 억제 하였다. 그러나 CV-40-Va-1의 항응고 활성은 thromin에 직접 작용하는 것이 아니라 antithrombin III 의존적 활성을 보였다. Sulfation에 의하여 CV-40-Va-1의 항응고활성의 증가와 다당의 desulfation시 상반된 결과에서 CV-40-Va-1의 황산기가 항응고활성의 중요한 인자임을 알 수 있었다. CV-40-Va-1을 TFA로 부분가수분해하여 얻은 획분들(Fr.I, Fr.II)에서는 항응고 활성이 감소하였으나 분자량 1,000정도로 추정되는 획분(Fr.II)은 오히려 혈소판응집을 강력하게 억제하였다.

Objectives : It is the object of Qigong therapy to promote the circulation of Qi and blood, and to relieve mentality by way of warming lower Danjon. In this study, to prove that Qigong therapy could actually subside heat on upper or middle Danjon and warm the temperature on lower Danjon, we observed the thermal changes of upper, middle, lower Danjon before and after Qigong therapy and compared them. Methods : We selected 16 patients, treated Qigong therapy and examined by D.I.T.I.(Digital Infrared Thermographic Imaging) before and after Qigong therapy, among patients who visited. Qigong clinic, Kangnam Korean hospital, Kyunghee University(Daechi-2dong, Kangnam-Gu) from april to october, 1999. We watched the difference of temperature among upper, middle, lower Danjon before and after Qigong therapy, and used student T-test(paired type, 2 tail) for proving effects of Qigong therapy statistically. Conclusions 1. The difference of temperature$({\Delta}T)$ between upper(Ex-HN3) and lower Danjon(CV4) significantly decreased about $0.55^{\circ}C$ after Qigong therapy(p<0.01). 2. The difference of temperature${\Delta}T$ between middle(CV17) and lower Danjon(CV4) significantly decreased about $0.39^{\circ}C$ after Qigong therapy(p<0.05). 3. The difference of temperature${\Delta}T$ between upper(Ex-HN3) and middle Danjon(CV17) decreased about $0.25^{\circ}C$ after Qigong therapy, but it was not statistically significant.

Objectives This study to investigate the effect of oriental medical treatment including moxa bucket moxibustion on children with nocturnal enuresis. Methods We treated five cases of enuretic children with oriental medical treatment like moxa bucket moxibustion on Gwanwon(CV4) at every cases and acupuncture, TDP, herbal medicine at some cases. To investigate relapse, we followed up by telephone at least about 3 months after the end of the therapy. Results After the treatment, the number of enuresis before and after the treatment were compared. The number was decreased by 67% or more all cases. Conclusions According to the result, oriental medical treatment including moxa bucket moxibustion is considered to be effective on the nocturnal enuresis and further study is needed with more cases.
