Objectives : Hypothyroidism is the most common pathological disease of the endocrine system. Morinda Officinalis Radix has been used in treatment of Yang deficiency. In this study, we investigated the therapeutic effects of Morinda Officinalis Radix on a rat model of hypothyroidism induced by 6-propyl, 2-thiouracil (PTU). Methods : Two-month-old Sprague-Dawley male rats were used with injection of PTU which induced rats into hypo-thyroidism. During 2 weeks, rats were treated with Morinda Officinalis Radix and thyroxine. Body weights were checked every week, the after 4 weeks, biochemical analyses were performed. The levels of T3, T4 and TSH was measured by EILSA. Results : In the Morinda Officinalis Radix group, we could observe the level of T4 significantly increased and TSH level significantly decreased. Conclusions : Morinda Officinalis Radix could help the thyroid to produce thyroid hormones under PTU suppression. There is no harm effect on liver and kidney function, or other metabolism. According to these results it could help to treat hypothyroidism patients and relieve their symptoms.

Purpose: This study was conducted to investigate the muscular strength & stamina improvement and muscle anti-fatigue effects of Morinda officinalis How after long term administration. Methods: 4-6 weeks old ICR mice were used in this study and we administered the water soluble extracts of Morinda officinalis How in the concentration of 1, 10. 100/mg/0.3ml to each 5 mice (ATS group) and same volume of normal saline was administered to 5 mice (control group) once a day for 90 or 120 days. After the administration we performed the swimming exercise test and the grip strength test. And we measured the concentration of glucose and the activity of lactate dehydrogenase in plasma regarded as biochemical indicator related with the muscular fatigue. Results: In swimming exercise test, all ATS groups showed increased time compared with relative control group after 90 days administration. After 120 days adminstration 100/mg/0.3ml ATS groups showed increased results. In grip strength test, all ATS groups showed increased grip strength compared with relative control group after 90 days administration. After 120 days adminstration 10/mg/0.3ml ATS groups showed increased result. All the results of plasma glucose didn't showed statistically significant difference after 90 and 120 days administration. In the plasma concentration of activity level of lactate dehydrogenase, all ATS groups didn't showed statistically significant difference compared after 90 days administration. Conclusion: This study show that Morinda officinalis How can increase the muscular strength & stamina and anti-fatigue effect.

Morinda officinalis How. (Rubiaceae) has been used as tonic, warming, sex impulse and anti-inflammatory agents. Two known anthraquinones, rubiadin-1-methyl ether (I) and rubiadin (II) were isolated from root of M. officinalis. Their structures were identified using NMR and literature comparisons. The contents of I in eighteen M. officinalis were evaluated by HPLC-PDA. Chromatography was performed using a reversed-phase system with Luna $C_{18}$ (2) column and acetonitrile-water (50:50, v/v) with a flow rate of 1.0 mL/min under UV 280 nm. Under these conditions, the content of rubiadin-1-methyl ether was 0.013%.

Purpose: This study was conducted to investigate the muscle anti-fatigue effects of Morindae officinalis Radix liquid extract. Methods: 4-6 weeks old ICR rats are used in the study, and we administered the extracts powder of Morinda officinalis concentration of 1, 10, 100mg/0.3 ml to each to rats(MO group) once a day for each 30 and 60 days. After 30 and 60 days, we examined the plasma concentraion of lactate dehydrogenase, glucose. And we measured the persistent time of swimming exercise test and conducted grip strength test Results: We found that there are no significantly differences between the control and the treatment group in the plasma concentration of activity level of lactate dehydrogenase. And we found that in 30days group, level of glucose concentration is significant. In swimming exercise test, as administration time and concetration growed up, swimming time is increased. And in grip strength test, as concentraion is growed up, grip strength is increased. Conclusion: This study show that Morinda officinalis is effective against muscle fatigue.

파극천은 전통적으로 피부염증 치료에 사용되어온 약초이다. 본 연구에서는 파극천 뿌리를 고온($132^{\circ}C$) 및 고압($1.2kgf/cm^2$)에서 15분 동안 처리한 후 추출물을 분리하여 이들의 MMP-1 효소 억제 효능을 확인하였다. 고온고압 처리된 파극천 추출물의 성분변화를 확인한 결과, 고온고압 처리가 파극천 추출물의 페놀 및 플라보노이드 함량을 약 1.5배 이상 증가시키는 것으로 나타났다. DPPH 및 superoxide 라디칼 소거능을 확인해 본 결과 $500{\mu}g/mL$에서 각각 79.25%, 94.5%의 라디칼 소거 효과가 나타났으며, 기존 추출물 대비 농도 의존적으로 활성 증가를 확인하였다. 또한, 항염 효과를 5-LOX 및 COX-2 저해능을 통해 확인한 결과 고온고압 처리된 파극천 추출물에서 약 45% 증가된 저해능이 나타났다. 이에 자외선에 대한 고온고압 처리된 파극천 추출물의 피부 콜라겐 단백질 분해효소 발현 저해 양상도 농도 의존적으로 발현이 억제되었으며 약 16% 정도 저해 효과가 유의적으로 증가되었다. UVB의 세포보호 효과도 고온고압 처리된 파극천 추출물을 함께 처리하였을 때 세포생존율이 증가됨을 확인할 수 있었다. 결론적으로 파극천 추출물에 고온고압 처리를 통해 기존 추출물보다 뛰어난 항산화, 항염 및 MMP-1 발현 억제 효과의 증가를 확인하였으며, 앞으로 기능성 소재로서 화장품에 응용될 수 있을 것으로 사료된다.

Objectives : We have been used many herbal medicines after processing to improve the effect, decrease toxicity and side-effect, and change property. We have studied the physico-chemical change and HPLC pattern of Morindae Radix by means of processing method. Methods : This study was investigated the contents of loss on drying, residue on ignition, residue on acid insoluble ignition, 50% ethanol extract and HPLC pattern of Morindae Radix(Morinda officinalis How.) by processed and non-processed. We have conducted Morindae Radix and Damnacanthi Radix which is circulated in herbal medicine market by forgery. Processed Morindae Radix was prepared by heating of added to salt(SP), liquor(LP) and Glycyrrhizae Radix solution(GP) for 20-40 minutes. Results and Conclusions : From this analysis, we found that the content of 50% ethanol extract was increased by processing method. And we were detected distinguishable marker of processed and non-processed from Morindae Radix(Morinda officinalis How.) by HPLC pattern analysis.

Alzheimer's disease(AD) is progressive neurodegenerative disease, which is pathologically characterized by neuritic plaques and neurofibrillary tangles associated with the acetylcholinesterase, apolipoprotein E and butylcholinesterase, and by mutations in the presenilin genes PS1 and PS2, and amyloid precursor proteins (APP) overexpression. The present research is to examine the inhibition effect of MDOF on PS-1, PS-2 and APP overexpression by detected to Western blotting. To verify the effects of MDOF on cognitive deficits further, we tested it on the scopolamine-induced amnesia model of the mice using the Morris water maze tests, and there was ameliorative effects of memory impairment as a protection to scopolamine. MDOF only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, whereas blood glucose level was shown to attenuate the amnesia induced by scopolamine and inreased extracelluar serum level compared with only scopolamine injection. In conclusion, studies of MDOF that has been know as anti-choline and inhibition ablilities of APP overexpression, this could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer's disease.

본 연구에서는 파극천 추출물의 수면연장 시간, 항 경련효과 및 시험관내에서 파극천의 각 분획별 활성산소의 소거능을 관찰하여 본 결과 pentobarbital을 투여한 대조군의 수면 유도시간 및 수면시간($3.77{\pm}0.56$분, 수면시간 $68.3{\pm}6.8$분)이 파극천 추출물(200 mg/kg)을 전 처리하고 pentobarbital을 투여함으로써 수면유도 시간($3.95{\pm}0.56$분) 및 수면시간($110.4{\pm}10.3$분)이 연장되었다. PTZ에 의해 유도되는 경련 발작이 대조군 $4.9{\pm}0.98$인데 비해 파극천(200 mg/kg)의 전처리로 경련박작이 $3.2{\pm}0.54$로 현저히 억제되었으며 이 결과는 PTZ의 경련발현시간, 경련유지시간 및 사망시간에 미치는 파극천의 영향과 유사하였다. 뇌중 GABA 함량은 PTZ의 투여로 정상군에 비하여 억제되던 것이 파극천의 전처리로 증가 되었으며, GABA-T의 활성과 지질과산화의 함량은 PTZ의 투여로 각각 증가되던 것이 파극천 추출물의 투여로 억제되었다. 시험관내에서 PTZ로 유도된 뇌조직중의 hydroxy radical의 생성량은 butanol 및 dichlomethane 분획의 첨가($20{\times}10^{-2}g/ml$)에서 약 35%에서 50%까지 감소하였다.
