  • Objectives Although ginseng has been reported to protect neuronal cells and improve various cognitive functions, relationship between ginseng supplementation and response inhibition, one of the important cognitive domains has not been explored. In addition, effects of ginseng on in vivo human brain have not been investigated using the diffusion tensor imaging (DTI). The purpose of the current study is to investigate changes in intrusion errors and white matter microstructure after Korean Red Ginseng supplementation using standardized neuropsychological tests and DTI. Methods Fifty-one healthy participants were randomly allocated to the Korean Red Ginseng (n = 26) or placebo (n = 25) groups for 8 weeks. The California Verbal Learning Test was used to assess the number of intrusion errors. Intelligence quotient (IQ) was measured with the Korean Wechsler Adult Intelligence Scale. Depressive and anxiety symptoms were evaluated using Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, and Hopkins Symptom Checklist-25. The fractional anisotropy (FA) was measured from the brain DTI data. Results After the 8-week intervention, Korean Red Ginseng supplementation significantly reduced intrusion errors after adjusting age, sex, IQ, and baseline score of the intrusion errors (p for interaction = 0.005). Change in FA values in the left anterior corona radiata was greater in the Korean Red Ginseng group compared to the placebo group (t = 4.29, p = 0.04). Conclusions Korean Red Ginseng supplementation may be efficacious for improving response inhibition and white matter microstructure integrity in the prefrontal cortex.

  • 성체흰쥐의 경우 항암제인 싸이클로포스파마이드(CY)처리로 퇴축된 가슴샘은 2주 후에 정상조직으로 재생된다. 가슴샘 발생과정에서 이미 알려진 SDF-1 신호전달의 중요성과는 달리 성체의 가슴샘 재생과정에서 그 역할에 관해서는 알려진 바 전혀 없다. 본 연구의 목적은 발생중인 가슴샘에서 발현이 증가된다고 이미 알려져 있는 SDF-1이 성체의 가슴샘재생과정에서 어떤 발현 양상을 보이는지를 조사하는 것이다. 본 연구에서는 사이클로포스파마이(cyclophosphamide: CY)를 투여하여 가슴샘의 급성 퇴축을 유발시킨 후, 가슴샘 재생과정동안 SDF-1의 발현 특성을 면역조직화학, 이중면역염색 형광법, 역전사 중합효소 연쇄반응법을 이용하여 조사하였다. 그 결과, SDF-1은 가슴샘의 급성 퇴축 이후 7일째 되는 시기에 mRNA와 단백질의 양이 급격히 증가하였으며, 이중면역염색 형광법을 통해 큰포식 세포와 위치적 분포가 일치함을 확인하였다. 따라서, 본 연구 결과들을 통해 SDF-1은 가슴샘의 급성 퇴축 초기 과정에서 나타나는 손상된 세포를 처리하는 큰포식 세포의 기능 조절에 관여할 것으로 생각된다.

  • Objective: To improve the N biomarker in the amyloid/tau/neurodegeneration system by radiomics and study its value for predicting cognitive progression in individuals with mild cognitive impairment (MCI). Materials and Methods: A group of 147 healthy controls (HCs) (72 male; mean age ± standard deviation, 73.7 ± 6.3 years), 197 patients with MCI (114 male; 72.2 ± 7.1 years), and 128 patients with Alzheimer's disease (AD) (74 male; 73.7 ± 8.4 years) were included. Optimal A, T, and N biomarkers for discriminating HC and AD were selected using receiver operating characteristic (ROC) curve analysis. A radiomics model containing comprehensive information of the whole cerebral cortex and deep nuclei was established to create a new N biomarker. Cerebrospinal fluid (CSF) biomarkers were evaluated to determine the optimal A or T biomarkers. All MCI patients were followed up until AD conversion or for at least 60 months. The predictive value of A, T, and the radiomics-based N biomarker for cognitive progression of MCI to AD were analyzed using Kaplan-Meier estimates and the log-rank test. Results: The radiomics-based N biomarker showed an ROC curve area of 0.998 for discriminating between AD and HC. CSF Aβ42 and p-tau proteins were identified as the optimal A and T biomarkers, respectively. For MCI patients on the Alzheimer's continuum, isolated A+ was an indicator of cognitive stability, while abnormalities of T and N, separately or simultaneously, indicated a high risk of progression. For MCI patients with suspected non-Alzheimer's disease pathophysiology, isolated T+ indicated cognitive stability, while the appearance of the radiomics-based N+ indicated a high risk of progression to AD. Conclusion: We proposed a new radiomics-based improved N biomarker that could help identify patients with MCI who are at a higher risk for cognitive progression. In addition, we clarified the value of a single A/T/N biomarker for predicting the cognitive progression of MCI.

  • ${\alpha}_2$-Adrenoceptor antagonists, which can enhance synaptic norepinephrine levels by blocking feedback inhibition processes, are potentially useful in the treatment of disease states such. as depression, memory impairment, impotence and sexual dysfunction. (10bS)-1,2,3,5,6,10b-Hexahydropyrrolo[2,1-a]isoquinoline oxalate (YSL-3S) was evaluated in several in vitro biological tests to establish its pharmacological profile of activities as an ${\alpha}_2$-adrenoceptor antagonist. Saturation binding assay revealed that$^{3}[H]$rauwolscine bound to the $\alpha$$_2$-adrenoceptors with a Kd value of 6.3$\pm$0.5 nM and a Bmax value of 25l$\pm$39 fmol/mg protein in rat cortical synaptic membranes. Competitive binding assay showed that YSL-3S inhibited the binding of$^3[H]$rauwolscine (1 nM) in a concentration-dependent manner with a Ki value of 98.2$\pm$12.1 nM while it did not inhibit the binding of [$^3$H]cytisine (1.25 nM) to neuronal nicotinic cholinergic receptors. The Ki values of yohimbine, clonidine and norepinephrine for $^3[H]$rauwolscine binding were 15.8$\pm$1.0, 40.1$\pm$5.9 and 40.0$\pm$11.5 nM, respectively. In addition, the binding affinity of YSL-3S for ${\alpha}_2$-adrenoceptors was higher than that of its antipode and the racemic mixture. The functional activity of YSL-3S at the presynaptic ${\alpha}_2$-adrenoceptors was assessed using the prostatic portion of the rat vas deferens. Clonidine inhibited field-stimulated contractions of the vas deference in a dose-dependent manner. The presence of YSL-3S or yohimbine caused a parallel, rightward the dose-response curve of clonidine in a dose-dependent manner, indicating an antagonistic action at the presynaptic ${\alpha}_2$-adrenoceptors. The $pA_2$values of yohimbine and YSL-3S were 7.66$\pm$0.13 and 6.64$\pm$0.18, respectively. The results indicate that YSL-3S acts as a competitive antagonist at presynaptic ${\alpha}_2$ -adrenoceptors with a potency approximately ten times lower than yohimbine, but is devoid of binding affinity for neuronal nicotinic cholinergic receptors.

  • 목적 : 계명대학교 의과대학 치료방사선과학교실의 의료진들이 개발하여 사용하고 있는 방사선수술 시스템인 Photon Knife를 이용하여 뇌동정맥기형을 치료하고 그 효과를 보고자 하였다. 대상 및 방법 : 1993년 12월부터 2000년 10월까지 뇌동정맥기형으로 계명대학교 동산의료원 치료방사선과를 방문하여 Photon Knife로 방사선수술을 받은 환자는 30명이었다. 성별분포는 남자 20명, 여자 10명이며 연령분포는 7세부터 63세로 평균 34세이었다. 뇌동정맥기형(AVM nidus)의 위치는 전두부, 두정부, 시상부 순이었고 변소의 장경은1.2 cm에서 5.5 cm으로 평균 2.9 cm이었으며 표적용적은 0.5 cc에서 20.6 cc로 평균 6.8 cc이었다. 대부분에서 회전 중심선량의 80% 등선량곡선(Isodose line)에 1,500~2,500 cGy (중앙값 2,000 cGy)를 조사하였다. 1개의 회전중심점을 사용한 환자는 25명이었고 2개의 회전중심점을 사용한 환자는 4명이었으며 1명은 4개의 회전중심점을 사용하였다. 추적검사는 방사선수술 후 6개월에서 1년 간격으로 전산화단층촬영이나 자기공명영상을 시행하여 병소(nidus)의 완전소실이 관찰되면 뇌혈관조영술이나 자기공명영상 혈관조영촬영술로 확인하였다. 추적관찰기간은 10개월에서 103개월로 중앙추적기간은 39개월이었다 결과 : 전체환자 중 영상학적으로 20개월 이상 추적 관찰된 환자는 20명이었으며 그 중 70% (14/20)에서 완전폐색을 관찰하였다. 병소의 장경에 따라 작은 뇌동정맥기형(<2 cm) 환자 4명은 모두 완전폐색이 되었고 중간크기 뇌동정맥기형(2~3 cm은 80%, (8/10)에서 완전폐색이 되었으며 2명은 부분폐색이 되었다. 큰 뇌동정맥기형(> cm)에서는 환자 6명 중 1명만 완전폐색을 보였고 5명에서는 부분폐색은 되었으나 3년재에도 남아 있는 환자 3명은 재 방사선수술을 하였고 이 중 20개월 이상 추적검사를 받은 1명은 재 방사선수술 후 완전폐색이 되었다. 방사선 수술전 신경발작(seizure)을 주소로 내원한 환자 10명은 방사선수술과 약물투여로 신경발작의 재발은 없었다. 뇌출혈이 있었던 11명 중 1명에서 방사선수술 후 19개월, 61개월에 다시 출혈하였으나 입원 치료 후 회복되었다. 방사선수술에 의한 심각한 부작용은 관찰되지 않았다. 결론 : 이상으로 볼 때 저자들에 의해 개발된 Photon knife를 이용한 방사선수술은 뇌동정맥기형에서 수술이 불가능한 위치에 있거나 수술을 거부하는 환자 중 병소의 장경이 3 cm 이하이거나 병소의 용적이 10 cm$^{3}$ 이하인 뇌동정맥기형의 치료에 안전하고 효과적인 방법으로 사료된다. 또한 10 cm$^{3}$ 이상의 용적이 큰 뇌동정맥기형에서는 순차적(staged) 방사선수술을 처음부터 고려할 필요가 있을 것으로 사료된다.

  • The purposes of this study were to identify the contents, frequency of use, and the rationales of folk remedies frequently used for first aid at home for stomachache, vomiting, strain, food poisoning, vaginal bleeding, or wounds of snake or dog bite, or bee sting. As the method of the study, data were collected by conducting a questionnaire of 185 persons, who filled it out or who were interviewed from May to August in 1998. The collected data was analyzed by using frequency and the rationales for the contents of the folk remedies were described base on literatures. The results were as follows,. 1. The folk remedies for stomachache in frequency order were 'warming the abdomen', 'rubbing the abdomen with a hand', or 'pricking a finger to bleed', which have the rationals. 2. The folk remedies for vomiting in frequency order are 'drinking water of watery radish' and 'pricking a finger to bleed', which have the rationales. 3. The folk remedies for strain in frequency order are 'soaking the affected area into cold water or applying an ice pack' and 'after soaking jasmine in water, making a dough with flour, and then attaching it on the affected area', which have the rationales, Additionally, although the frequencies are low, 'drinking brewed Achyranthis Radix' and 'applying brewed leaves and stalks of Sambuci Cortex' have the rationales. 4. The folk remedies for food poisoning in frequency order are 'drinking black beans and licorice brewed together' and 'eating mung beans', which have the scientific grounds. 5. The folk remedies for bloody discharge in frequency order are 'drinking brewed lotus root' and 'eating boiled chicken stuffed with root of bell-flower'. However, 'drinking brewed Thujae orientalis Folium' has the rationales. 6. The folk remedy for snake bite wounds that has the scientific grounds is 'sucking blood by a person without hurt in the mouth'. However, quite a lot of people apply alum or soy paste, which has no rationales. 7. The folk remedies for the bee sting in frequency order are 'after removing the sting, applying soy paste or sauce' and 'applying saliva'. No rationales for 'applying saliva' have been found. 8. The folk remedy for the dog bite wound that has the rationales is 'applying juice of leaves or stalks of Xanthii Fructus'. However, 85% of surveyed people use remedies that have no scientific grounds, such as 'applying burnt dog hair mixed with (sesame) oil' and 'applying soy paste or sauce'. Various materials are used in folk remedies for first aid treatment as shown above. Some of the folk remedies have the rationales since their medicinal actions have been found. However, the medicinal actions of the majority have not been found, but only known that they are effective, Especially for the materials except botanical drugs, they are used without knowing the effects since their components and pharmacognosies have not been described in any literature. The results of this research may be used for materials to educate the surveyed people or to consult them. Accordingly, the folk remedies that have the rationales are required to continue to study to find out the effects.
