Subjects : A literature research on the constitution and medicinal effect & adaptation diseases of "Bullsusan". "Bullsusan" is a herbal prescription composed of Angelicae Gigantis Radix(當歸) and Cnidii Rhizoma(川芎). Objectives : Through the researching on the records of "Bullsusan" in Korean Traditional Medical Books, gain the literature evidence for adaptation to these days child labor as a pre-labor keeping herbal medicine. And have detailed consideration on the constitution of prescription and medicinal effect & adaptation diseases of "Bullsusan". Methods : First, researched the records of "Bullsusan" in Korean Traditional Medical Books which were included at A Series of Korean Medicine(韓國醫學大系) and analysed component ratio, nickname, herbal manufacture and drug processing method, medicinal effect and adaptation diseases. Second, referred related Korean and Chinese researches that examined the medicinal effect and adaptation diseases of "Bullsusan" by scientific experimentation. Conclusions : We found total 46 records of "Bullsusan" from 20 kinds of Korean Traditional Medical Books included at A Series of Korean Medicine. Prescription component ratio of Angelicae Gigantis Radix and Cnidii Rhizoma were 3:2, 1:1, 2:1, 1:1. 3:2 had most 20 records and 1:1 had second 14 records. Especially 1:1 had a tendency of having nickname "Goonguitang", but not must had. First herbal manufacture was powder, it had 8 records. First drug processing method was decocting with water and alcohol, had 19 records. Medical Effects of "Bullsusan" can be induced to next 8, that were "remove get bad blood, give birth new blood", "easy labor by reducing fetal volume", "acceleration of labor", "test of fetal survival, elimination of dead embryo", "elimination of placenta", "revive", "allaying pain", "nourish the blood". From these medical effects, 9 adaptation diseases can be induced. That were "threatened abortion", "womb ache and vaginal bleeding by spontaneous abortion", "pre-labor keeping(prevention of hard labor)", "acceleration of labor", "hard labor", "missed abortion", "postnatal vaginal bleeding, dizziness, asthma, headache, womb ache", "postnatal mastoptosis and mastodynia", "first aid symptom like as dizziness, unconsciousness, stroke caused by excessive bleeding". The medical effect of "acceleration of labor" and "elimination of placenta" have been examined by modern clinical research. The effect of "remove get bad blood, give birth new blood", "allaying pain" and "nourish the blood" have been examined by modern experimental study. But overdosing on "Bullsusan" to pregnant mouse can cause natural abortion, so the proper dose of "Bullsusan" in pregnant period is very important.

Microwaves are non-ionizing electromagnetic waves of frequency between 300MHz to 300GHz and positioned between the X-ray and infrared rays in the electromagnetic spectrum. In recent years, the use of microwave for extraction of ingredient from plant material has shown remarkable research interest and potential. Scutellaria radix has been used as a traditional medicine for a variety of diseases. It has been reported to exert beneficial health effects, such as anti-bacterial, antiviral, anti-inflammatory, and free-radical scavenging. Oxidative stress or the accumulation of reactive oxygen species (ROS) leads neuronal cellular death and dysfunction, and it contributes to neuronal degenerative disease such as Alzheimer's disease, Parkinson's disease and stroke. In this study, we aimed to compare the neuroprotective and antioxidant effect of Scutellaria radix extracted by different methods using hot-water extraction (SBE-DW) or microwave extraction (SBE-DW-MW). As a result, we first examined HPLC analysis of hot-water and microwave extracts of Scutellaria radix. The hot-water and microwave extracts of Scutellaria radix showed the discernible difference patterns of HPLC analysis. Microwave-water extracts of Scutellaria radix increased DPPH radical scavenging activity more than hot-water extraction. Microwave-water extracts of Scutellaria radix also showed neuroprotective effects and ROS inhibition against glutamate-induced oxidative stress in mouse hippocampal HT22 cells, but hot-water extraction not showed. In addition, the phosphorylation of MAPKs induced by glutamate insult was prevented by microwave-water extracts of Scutellaria radix. Thus, these results suggested that microwave extraction can be utilized for improving the extraction efficiency and biological activity of Scutellaria radix.

Objectives : A traditional herbal prescription, Kyung-Ok-Ko (KOK), has long been used in oriental medicine as an invigorant for age-related diseases, such as amnesia and stroke. However, the beneficial value of KOK for immune responses is largely unknown. Based on the above mentioned effects of KOK, other previous reports, and its use in traditional medicine, we hypothesized that KOK displays beneficial effects against methotrexate (MTX)-induced immune suppression. Methods : We investigated the effects of KOK (0.6 g/kg/day, oral (p.o.)) on deteriorated immunity caused by MTX (2 mg/kg/day, p.o.) in an immune suppression mouse model. MTX was fed to mice once a day for 7 days. After the immune responses of the mice deteriorated by MTX treatment, KOK in water was fed to the mice once a day for 14 days. We then measured the expression levels of various cytokines, such as T helper cell (Th1, Th2) cytokines, and the number of immune cells, such as spleen T cells, B cells, and macrophages. Results : The data showed that MTX decreased Th1 profiles (interferon $(IFN)-{\gamma}$, interleukin (IL)-2, IL-12) and the number of immune cells, and increased Th2 profiles (IL-4, IL-5, IL-13), which were normalized significantly by post-administration of KOK. However, there was no significant difference in body-weight gain between MTX- and KOK-treated mice. Conclusion : These results indicate that KOK has immune-enhancing functions and reduces immunotoxicity of MTX, suggesting that supplementation with KOK will improve immune responses clinically and be useful for the prevention of immune-related diseases.

Glutamate는 포유류의 중추신경계에 분포하는 흥분성 신경전달물질로, 기억, 인지, 그리고 학습 등에 있어서 중요한 역할을 한다. 하지만 고농도의 Glutamate는 신경세포에 독성을 유발하여 신경세포사멸을 유도함으로써 알츠하이머병, 파킨슨병, 뇌졸중 등의 신경퇴행성질환을 일으키는 것으로 알려져 있다. 본 연구에서 아열대 천연물의 항산화 활성과 신경보호 효과를 분석하였다. 11종의 아열대 추출물 중에서 Salacca wallichiana 추출물 (SE)의 라디칼 소거활성이 뛰어난 것으로 나타났다. 그리고 SE의 신경보호 효과를 조사한 결과 glutamate로 유도되는 cell death로부터 신경세포를 보호하였다. 또한 glutamate로 유도되는 apoptosis로부터 HT22 세포를 보호하는 효과는 Annexin V와 PI로 염색한 후 flow cytometry를 통해 분석되었다. 추가적으로 H₂DCFDA 염색을 이용하여 SE가 glutamate로 유도되는 세포 내 활성 산소 종 (ROS)을 억제한다는 것을 확인했다. SE의 신경보호 효과는 oxidative stress로 유발되는 Mitogen-activated protein kinase (MAPK) signaling pathway를 억제함으로써 신경세포를 보호하는 것으로 나타났다. 결과적으로 SE가 신경퇴행성질환을 예방하기 위한 치료제 개발에 기여할 수 있음을 나타낸다.

중추신경계의 신경간세포가 파킨슨병과 뇌졸중과 같은 퇴행성 뇌 질환의 치료뿐만이 아니라 신경세포 발생과정에서의 중요성 때문에 최근에 커다란 관심의 대상이 되고 있다. 중추신경계의 발생과정 동안에, 중뇌의 도파민 신경세포의 형성은 두 가지의 분자생물학적인 기작에 의해서 결정된다. 첫째로, FGF-8, sonic hedgehog 그리고 전사조절인자 인 Nurr1이 도파민 신경세포의 형질을 결정짓는다. 또 다른 기작으로는, 전사조절인자 인 $Lm{\times}lb$와 $Pt{\times}3$가 중요하게 관련되어있다. 특히 Nurr1이 결핍된 생쥐에서, 타이로신수산화효소 (Tyrosine bydroxylase, TH) 면역양성 세포들이 중뇌흑색질에서 발견되지 않으므로 Nurr1이 도파민 신경세포의 발생에 필수적임을 알 수 있다. 본 연구에서는 도파민 신경세포의 형질을 유도하는데 있어서 Nurr1이 매개하는 기작을 연구하기 위해서 레트로 바이러스를 이용하여 Nurr1을 도입한 무한증식 신경간세포를 사용하였다. Nurr1 유전자의 과발현 만으로는 신경간세포에서 도파민 신경세포의 형질을 유도하지는 못하지만, 레티노이드 (retinoid, RA)와 폴스콜린 (forskolin, FK)을 처리하여 TH와 방향성 L-아미노산 탈카르복시화효소 (aromatic L-amino acid decarboxylase, AADC) mRNA의 발현을 유도하였다. 또한, Nurr1 과발현 신경간세포를 사람 별아교세포와 공동배양 하여 TH 발현량을 많이 증가시켰다. 이러한 공동배양실험에서, RA와 FK를 처리하면 TH의 발현수준이 더욱 더 증가함을 발견하였다. 이러한 결과들은 Nurr1 유전자를 도입한 사람 신경간세포가 파킨슨병 환자들에게 세포이식을 통한 유전자 치료의 유용성을 시사하고 있다.
