Objectives : This study was conducted to evaluate the effect and mechanism of Geupoongjibo-dan's relaxation of the tension of the blood vessel caused by Phenylephrine and KCI. Methods : In order to study the effect of Geupoongjibo-dan's relaxation of the blood vessel tension, Geupoongjibo-dan extract was infused into Phenylephrine and KCI-induced contracted rabbit aorta strips. To analyze the mechanism of Geupoongjibo-dan's effect on the blood vessel, Geupoongjibo-dan extract infused into Phenylephrine and KCI-induced contracted strips induced by agonists after treatment of N${\omega}$-nitro-L-arginine, Methylene Blue. Results : 1. Geupoongjibo-dan was very effective in relaxing the blood vessels contracted by Phenylephrine. 2. Geupoongjibo-dan was effective against Phenylephrine, than against KCI. 3. Geupoongjibo-dan's more relaxation effect on a blood vessel was terminated by N${\omega}$-nitro-L-arginine and methylene treatment. Conclusion : THis study showed that Geupoongjibo-dan's relaxation effect on a blood vessel is irrelevant to ${\alpha}$-adrenalin receptor, and it relaxes contracted vessels through cGMP channel.

The purpose of this investigation is to evaluate the effects of Samwha-tang(三化湯) Extracts on reversible forebrain ischemia experimentally induced from the occlusion of middle cerebral artery. The volume of cerebral ischemia, the volume of cerebral edema, and the change of pyramidal neuron of the CA1 area in hippocampus through light microscopy were investigated. we obtained the following results. The volume of the control group, which had ischemic damage was 21%, and the volume of the sample group, which had ischemic damage, was 16%. The ratio of the volume of the right/left hemisphere was 117.2 in the control group, and 108.8 in the sample group. Also, the light microscopy revealed that the pyramidal cells of CA1 area in hippocampus had many damages like changes into discontinuous and unsystematic forms. But, in the sample group, the cells were less damaged compared with the control group.

Objectives : The purpose of this investigation is to evaluate the effects of Woohwangcheongsim-won on neuronal death of hypoxic E18 cortical neuroblast. Methods : To evaluate the effect of Woohwangcheongsim-won on neuronal death caused by hypoxia, the survival rate of E18 cortical neuroblast was measured with MTT assay and the changes of several synaptic proteins and enzymes were investigated with the immunoblot assays. Results : The E18 cortical neuroblasts were added 50, 100, 500, 1,000, and $5,000{\mu}g/ml$ Woohwangcheongsim-won. They showed neurotoxicity, when the concentration of Woohwangcheongsim-won was above $1,000{\mu}g/ml$. The E18 cortical neuroblasts, which were added 50, 100, and $500{\mu}g/ml$ Woohwangcheongsim-won, were exposed 98% $N_2/5%\;CO_2$ for 3 hours to induce hypoxia, 3 days later, the survival rate of $50{\mu}g/ml$ Woohwangcheongsim-won was 141.5% when compared to the control group. On the immuneblot assays, the expressions of ${\alpha}$CaMKII, NR2A, NR28, PDE2, PSD-95, and eEF-$1{\alpha}$ were increased in normoxia, but those of NR2A, NR2B were decreased in hypoxia when compared to the control group. Conclusions : The data shows that the effects of Woohwangcheongsim-won on neuronal death of hypoxic E18 cortical neuroblast is a significant result.

Objectives : The purpose of this investigation is to evaluate the effect of Geupoongjibo-dan Extracts on Reversible Forebrain Ischemia in Mongolian Gerbils. Methods : The change rate of water content in cerebral tissues, the numercal change of the CA1 pyramidal neuron in the hippocampus, the change of delayed neuronal death(necrosis apoptosis) through light microscopy, the reactivity change of glycoprotein in neuronal membrane and the ultrastructural change of pyramidal neuron through electron microscopy caused by dalayed neuronal death were investigated. Results : 1. The change rate of water content in the normal group showed 78.90% on the third day, and 79.12% on the seventh day after an attack of ischemia. The rate in the control group showed 82.25% and 85.13%, respectively. The rate in the sample group showed a significant decrease: 81.72% and 83.66%. 2. Light microscopy revealed that the cells, continuous and systematic forms in the pyramidal cells of hippocampus, changed into discontinuous and unsystematic forms in the normal group when compared with the control group. The cells were less damaged in the sample group. 3. The mean of the numerical change of the CA1 pyramidal neurons in the hippocampus was 104 in the normal group. The mean of the control group was decreased to 27. The mean of the sample group was 44. 4. TUNEL staining examination reveals that the whole part of the hippocampus of the normal group had negative reactivity. As far as CA1 pyramidal neurons in the hippocampus, the control group had positive reactivity. The sample group was more positive than the control group. 5. Electron microscopy reveals that the ischemic injury of the control group had both necrotic and apoptotic morphology. The sample group was less necrotic, and more apoptotic morphology than the control group. 6. Lectin histochemisrical examination reveals that the normal group had positive reactivity to PNA and SBA in interneuron, and weak positive reactivity to WGA Con A LCA in intercelluar space. The reactivity to PNA and WGA decreased in the control group. The reactivity to PNA and WGA tended to increase in the sample group. Conclusions : The data shows that the effect of Geupoongjibo-dan Extracts on Reversible Forebrain Ischemia in MG is a significant result.

Objectives : The purpose of this investigation is to evaluate the effect of Chungpesagan-Tang Extracts on reversible forebrain ischemia in Sprague-Dawley rats. Methods : the volume of cerebral infarction and edema, the pathohistological change of neurons, the number of survived neurons, neurotransmitters through immunohistochemical methods, proteins connected with neurotransmitters through immunohistochemical methods and the pathohistological change of neurons through electro-microscopy were investigated. From these reseach data, the protection of neurons and the activity of brain cells were examined. Results : 1. The infaction volume of the control group was 23.9%, and that of the sample group was 16%. 2. The brain edema volume of the control group increased by 17% compared to the normal group and that of the sample group increased by 10%. 3. The light microscopy revealed that the neurons in the ischemia-induced area and CA1 area of hippocampus were most heavily damaged and that the sample group was less damaged compared with the control group. Most pyramidal neurons died in 7 days when brain ischemia was induced. 4. The number of survived pyramidal neurons in the CA1 area of the hippocampus were studied. The normal group had 93 neurons/mm, survived the control group(after 3 days) had 21/mm, the control group(after 7 days) had 3/mm and the sample group 33/mm. 5. The immunohistochemical methods revealed that: (1) In the control group, the sensitivity of GABA, NOS, DBH were increased, and those of Synapsin, eEF-$1{\alpha}$ decreased. NOS and DBH had positive reactions in the control group, but negative in the normal group. (2) In thd sample group, the sensitivity of GABA, NOS, DBH were attenuated, and those of NPY, Synapsin, CaMKII, eEF-$1{\alpha}$ increased when compared to the control group. 6. The electro-microscopy revealed that most neurons died by necrosis and some neurons died by apoptosis. Several imflammation cells appeared in the injured area of neurons. The number of neurons in the sample group that died by ischemia decreased. But, the number that died by apoptosis did not significantly change. Conclusions : The data shows that the effect of Chungpesagan-Tang Extracts on reversible forebrain ischemia in Sprague-Dawley rats is significant.

Objectives : This study was undertaken to study the action mechanism of Rhizoma Davalliae (RD) at parameter related to regulating bone density. Methods : We measured alkaline phosphatase activity and the contents : calcium, hydroxyproline, osteocalcin, calcitonin, and parathyroid hormone after the ovariectomized rats had been treated with RD for 30 days. Results : The following changes occurred: First, the serum calcium content and the calcitonin content, which decreased in ovariectomized rats, increased with RD treatment. Second, the serum alkaline phosphatase activity, the parathyroid hormone ativity, the osteocalcin content, the urinary calcium content, and the hydroxyprolin content-which increased in ovariectomized rats-decreased with RD treatment. Conclusions : These results show that RD treatment can recover abnormal calcium metabolic process by sex hormone inequality, promoting bone formation and inhibiting bone absorption.

신경교세포에서 황금추출물이 반응성 산소기에 의한 세포 사망을 방지할 수 있는지를 확인하기 위하여 사람의 glioama 세포주인 A172 세포를 사용하여 $H_2O_2$의 독성작용에 대한 영향을 조사하였다. 세포 사망 정도는 tryptan blue exclusion과 MTT reduction assay로 평가하였다. $H_2O_2$는 세포 사망을 유도하였으며 또한 세포내 ATP 함량을 감소시켰으며, 이러한 효과는 황금 추출물에 의해 방지되었으며 그 효과는 농도 의존적으로 나타났다. $H_2O_2$에 의한 세포 사망은 잘 알려진 flavonoid인 quercetin과 철착염제인 phenanthroline에 의해 방지되었으나, 항산화제인 DPPD나 Trolox에 의해서는 영향을 받지 않았다. $H_2O_2$는 poly (ADP-ribose) polymerase를 활성화시켰으며, 이러한 효과는 황금, quercetin 및 phenanthroline에 의해 억제되었다. 황금 추출물은 유기산화제인 t-buthyhydroperoxide 및 중금속인 수은에 의한 세포 사망을 방지하였다. 이러한 실험 결과는 황금 추출물이 $H_2O_2$에 의한 세포 사망을 방지하며 그 효과는 황금의 flavonoid 성분이 철과 결합하여 $H_2O_2$로부터 hydroxy radical의 생성을 억제함으로써 나타나는 것으로 추측된다.

This study was designed to investigate the effects of Korean Lycii Fructus water extract in Pb-administered rats. The Pb exposed rats were given 100 ppm and 200 ppm in the distilled water. Sixty male Sprague-Dawley rats weighing between 90 and 110g were blocked into 6 groups according to body weight. The control group was fed a normal diet, without lead. The experimental groups, which was fed a normal diet plus 100 ppm and 200 ppm lead, and one group received a normal diet plus Lycii Fructus water extracts. The results: the Food intake, the weight gain, and the kidney weight content in the cadmium added groups were lower than those in the Lycii Fructus water extracts group. The contents of Pb in the kidneys of the rats were determined by using ICP(lnductively Coupled Plasma Spectrophotometer). The accumulation of lead in the kidney was lower in the Lycii Fructus water extracts group. The Plasma levels of renin activity was higher in the lead administration groups, as compared with the Lycii Fructus water extracts. Plasma levels of aldosterone activity was higher in the lead administration group, as compared with Lycii Fructus water extracts. These results suggest that Lycii Fructus water extracts has a lowering effects on the accumulation of pb on kidney and it is believed that the Lycii Fructus water extracts have some protective effects on lead-induced nephrotoxicity in rats, but the mechanism of these effects was obscure.

Background and Purpose : Transcranial doppler ultrasonography(TCD) is a noninvasive and nonradioactive technique for evaluation of the hemodynamics in large cerebral vessels. Sahyangsohap-won(SS) has been considered to be effective for the treatment of various disease, especially cerebrovascular, cardiovascular, and psychosomatoform disorders. But, there is no study about the effect of SS on the cerebral hemodynamics in humans. The aim of this study was to assess the effect of SS on the changes in cerebral hemodynamics and the dose-dependant effect by using TCD. Subjects and Methods : 30 healthy subjects were randomly divided into three group: group 1 took no drug, group 2 took SS one pill, and group 3 took SS 2 pills. Changes in the mean blood flow velocity(MBFV) and pulsatility index(PI) in the middle cerebral artery were evaluated by means of TCD. We obtained hypercapnia with breath-holding and evaluated cerebrovascular reactivity with the breath-holding index(BHI). Systolic blood pressure(SBP), diastolic blood pressure(DBP), and heart rate(HR) were measured by means of ambulatory blood pressure monitoring. In group 2 and group 3, the evaluations were performed during the baseline and were repeated at 20, 40, and 60 minutes after SS administration. In group 1, the evaluation was performed at corresponding time intervals. Results : In mean values of MSFV, PI, SSP, DBP, and HR, no stastically significant differences were found between the 3 groups. However, BHI values were significantly lower in groups 2 and 3 than in group 1 at 40 minutes after SS administration(P<0.05, group 1 vs group 2, group 1 vs group 3 by post-hoc analysis: Scheffe's test) but in dose-dependant effect, there was no difference between group 2 and group 3. Conclusion : These results suggest that SS can decrease vascular resistance in cerebral small arteries or arterioles and enhance their distensibility. Further studies on larger numbers of subjects are needed to confirm these effects and the dose-dependant effects.

Objectives : In order to study the clinical efficiency of Dohwatang, based on Oriental Medical References, using experimental animals, we studied ulcers, gastric juice secretion, free acidity, total acidity, and the action of transport rates in the intestine. Methods : We used rats administered with the above herbs. Results : Dohwa-tang showed remarkable inhibitory effects on peptic ulcers, gastric juice secretion, free acidity, and total acidity in pyloricligated rat. It also showed remarkable inhibitory effects on the transportability in the large intestine of rats. But Dohwa-tang didn't show any remarkable difference on stressed rats. Conclusions : Dohwatang works better for chronic pyloristenosis-peptic ulcer and for diarrhea than acute stress ulcer.

Against the mutagen MNNG and NOPD with SOS chromotest, the antigenotoxic activity of MeOH-soluble extract was much more effective than that of the water-soluble one. When the extract was added to the certain concentration, the antigenotoxic acivity was enhanced. Against the mutagen NOPD with Ames test, the antimutagenic activity of MeOH-soluble extract was better than that of the water-soluble one. The 60.4% of the inhibition ratio for the revertant colony-forming unit was shown at 5 mg of MeOH-soluble extract per plate. Antimutagenecity test with SOS chromotest and Ames test were performed using water-soluble and MeOH-soluble extracts from of Gleditsia sinensis. The antioxidant activity of MeOH-soluble extract with the NBT method was higher than that of the water-soluble one.

Objective : There have not been studies on the oriental medicine research trends and qualitative analysis of Korean oriental medicine articles in Korea, particularly in the oriental medicine area. This study's purpose is to appreciate Korean oriental medicine's research trends and assess the quality of the Korean oriental medical journals' level. This study will help upgrade Korean oriental medical journals. Method : We found 93 stroke-related articles in the Journal of Korean Oriental Medicine, published between 1980(Volume 1) and 2001(Volume 45). We surveyed the institutes involved in each study, and the number of people in each study. We seperated by epidemiological study design, the studies into categories. Campbell and Stanley's study design into 6 categories, statistical methods into 13 categories. Next, we assessed the 41 articles by a checklist, which had 10 categories. The quality score was analyzed by survey variables over the period, which were divided by the date of publication: the 1980s, the first half of the 1990s, second half of the 1990s and 2000s. Results : 46.3% od the studies didn't use statistical methods. 56.1%, were case series studies by classification of epidemiological study design, and 53.6% were one-shot case studies designed by Campbell and Stanley's study design. The quality score was 58.33 point 60 is average. In quality level by Browman GP etc.'s, 83.0% of the studies were included in V levels. But, the quality scores were significant by presence of reviewer system, statistical method's usage, and over the period. Conclusion : The Journal of Korean Oriental Medicine needs to improve the quality its articles. To improve the quality of oriental medicine related articles, the following are necessary: working together, joint work of inter-educational system, strengthening of reviewer system, use of statistical methods, and consulting to the expert of research at the stage of study design.

Alcoholism is a chronic behavior disorder that disturbs the health, social, and economical functions by intaking alcohol repeatedly. Alcoholism includes some habituation, dependency, and addiction. It may be clinically silent or severe enough to lead to the rapid development of hepatic, renal and gastrointestinal failure. Alcoholism can also cause death. In this case, we administrated saenggangunbitang and sungjoocheonggantang to a patient suffering from alcohoism and its withdrawal symptoms. After administration of saenggangunbitang-sungjoocheonggantang medication, clinical symptoms, including liver function with diabetes mellitus and splenomegaly improved. saenggangunbitang-sungjoocheonggantang showed desirable effect on alcoholism symptoms.

Paraquat is one of the widely used herbicides. But it is fatal, if it is consumed by people. Paraquat poisoning causes acute renal failure, hepatic dysfunction, and progressive respiratory failure. There are no effective antidotes to paraquat. This report is about one case's treatment for acute hepatitis caused by paraquat. The patient was hospitalized in the Department of Internal Medicine, Wonkwang University Oriental Medical Hospital in Chonju. The patient received the following treatments while in an acute stage : Gamdutanggamibang(甘豆湯加味方), which consists of Radix glycyrrhizae(甘草), Semen mungo(綠豆), burned powder of Rhizoma rhei(大黃炒炭末), Succus phyllostachyos(竹瀝), chinese ink(墨汁) and fluid therapy. The patient received Sagunjatanggamibang(四君子湯加味方) while in a chronic stage. The patient improved faster with the above treatments than with the conventional treatment. We hope that this report will help widening the clinical range of oriental medicine, and improve systemic efforts in treating paraquat poisoning cases.

In western medicine, there are some reports about herbal medicine induced hepatitis, but in oriental medicine, there are few reports about that. We experienced one case of drug acute cholestatic-hepatitis in the treatment of oriental medicine for HNP. We treated the patient with acupuncture, physical therapy and herb medicine. The patient's symptoms improved after two weeks of treatment. In the course of treatment, the patient intermittently complained of general weakness, nausea, yellowish urin, dyspepsia, and abdominal discomfort. We recognized that total bilirubin(7.2mg/dl), direct bilirubin(5.5mg/dl), serum transaminase(AST 360U/L, ALT 354U/L), alkaline phosphatase(16.6 K/A), urobilinogen(++) and bilirubin(++) were elevated. We diagnosed drug induced hepatitis. We stopped giving herb medicine and began giving Saeng gan gunbi-tang and Injin-oryung-san. Saeng gan gunbi-tang and Injin-oryung-san have been used to treat hepatic disease and have been known to have beneficial effects. After 3weeks on medication, the clinical symptoms and liver function improved. So, we report this case to bring more attention to the safety and toxicity of herbal medicine.

Cheiro-oral syndrome is characterized by a partial sensory disturbance in one hand and the ipsilateral oral comer. Its lesion is on the sensory track, and it is comparatively small. Most studies are case studies. These studies reported less than 10 cases. We studied two cases. In one, we observed intracranial hemorrhage involving left thalamus, posterior limb of internal capsule about 5cc in brain computed tomographic scan. The case was shown paresthesia of the right hand and ipsilateral comer of the mouth. The patient also complained about disturbing dysstereognosis and disorder of graphaesthesia. In the other case, we observed nodular calcification at the left basal ganglia external capsule in brain computed tomographic scan. The patient also complained about dysesthesia of the right thumb and index finger, fatigue and verbal disturbance. These cases appeared to be typical strokes in the acute phase, but after acute phase, they had dysethesia in the hand and periord for three months.

Monoplegia is the paralysis of either the upper or lower limb. Monoplegia is commonly caused by an injury to the cerebral cortex; it is rarely caused by an injury to the internal capsule, brain stem, or spinal cord. Most cerebral cortex is derived from the occlusion of a brain cortex blood vessel due to thrombus or embolus. According to motor homunculus, lower limb monoplegia occurs from limited damage to the most upper part of the primary motor area(Brodmann's area 4, located in precentral gyrus). Clinically, lower limb monoplegia due to brain cortical infarction is commonly misunderstood as monoplegia due to spinal injury because the lesion is situated at the most upper part of precentral gyrus. We had many difficulties in finding lesion on brain CT, but we diagnosed two patients correctly by using an MRI, who have lower limb monoplegia due to brain cortical infarction oriental treatment.

Ascites is commonly caused by portal vein pressure accentuation or peritoneal disease. Also, the use of diuretic and ascitic puncture have been the mainstays of ascites treatment. Objective : Experimental studies were done to research the effects of herbal medication on diseases with ascites (ex. liver cirrhosis, peritoneal carcinoma) on two patients. Methods : For measuring the response about the ascites, we observed this clinical symptoms : weight, abdominal circumference (umbilical circumference, upper abdominal circumference), and lab finding. Result : In both cases, clinical symptoms and ascites improved with herbal medication. Second, abdominal circumference decreased. Third, there was no electrolyte imbalance. Conclusion : This test shows that herbal medication has a strong effect on decreasing the intractable ascites.

We had one female ALS patient. The patient was diagnosed with ALS by EMG and Symptoms. We diagnosed the patient as Jinshang(筋傷) and Pishenyangxu(脾腎陽虛). We gave Shaoyaogancao-tang jiami(芍藥甘草湯加味) and Sijunzi-tang he Lizhong-tang jiami(四君子合理中湯加味) based on the differentiation of symtoms. We report the changes of the ALS patient's disphagia, lalopathy, and hypotonia after two months treatment with Riluzole and oriental medical treatment.
