This study was to investigate the neuroprotective effect of Ibuprofen by intranasal route against inflammationmediated by dopaminergic neurodegeneration in 1-methyl- 4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mice model of Parkinson’s disease (PD). Ibuprofen loaded sodium hyaluronate based mucoadhesive nanoemulsion (MNEI) was developed by using response surface methodology (RSM) and was characterized. Male C57BL/6 mice were first treated with four intraperitoneal injections of MPTP (20 mg/kg of body weight) at 2 h intervals followed by Ibuprofen for 2 consecutive weeks at 2.86 mg/kg of body weight per day. Optimal MNEI containing 3 % Labrafil M 1944 CS as oil phase, 36 %of Accenon CC and Transcutol P at 3:1 ratio and 0.5 % sodium hyaluronate was stable, non-ciliotoxic with 46.3 ± 2.28 nm as average globule size PdI value and TEM result showed the narrow size distribution of MNEI. The result showed that all three independent variables had a significant effect (p\0.05) on the responses. In-vivo results revealed significant reduction of MPTP-mediated dopamine depletion after nasal administration of Ibuprofen through MNEI. MPTP intoxication significantly decreased striatal DA content to 29.92 % which was elevated to 58.21 % after Ibuprofen treatment using MNEI. Significant improvement in motor performance and gross behavioural activity of the mice was observed through the findings of rota-rod and open field test findings. Findings of the investigation revealed that Ibuprofen through developed MNEI was shown to protect neurons against MPTP-induced injury in the striatum and could be a promising approach to treat PD.

The effect of Anemarrhena asphodeloides ethanolic extracts on hair growth effect in mice
Jang-Soon Park 한국융합학회 2018 한국융합학회논문지 Vol.9 No.8
여포 상피세포에 우수한 모발성장 촉진효과를 보이는 minoxidil의 단점을 보완하고자 대체의학제재로서의 모발 성장 촉진제로 지모를 연구하였다. 지모과(知母科)의 뿌리식물인 지모(知母)는 해열제, 항 당뇨병, 항우울제, 항염제 등으로 이용되고 있는 한국의 전통적인 약용식물이다. 지모 에탄올 추출물을 마우스의 등에 도포하여 관찰하였는데 모든 그룹의 마우스에서 체중과 음식 섭취량은 유의한 차이를 보이지 않았다. 지모 에탄올 추출물은 혈청 조성의 변화 없이 왕성한 모발성장 촉진효과를 보임으로써 향후 모발성장 촉진 제로서 유용한 가치가 있으리라 사료된다. We have studied anemarrhena asphodeloides, a hair growth promoter as an alternative medicine agent to compensate for the disadvantages of minoxidil, which has excellent hair growth promoting effect on follicular epithelial cells. anemarrhena asphodeloide, an Rhizome plant of aemarrhena asphodeloide family, is a traditional medicinal plant used in Korea as an antipyretic, antidiabetic, antidepressant, antiinflammatory. We applied and observed anemarrhena asphodeloides ethanol extracts to the back of mice, and there was no significant difference in body weight and food intake among all groups of mice. The ethanol extract of anemarrhena asphodeloides showed vigorous hair growth promoting effect without changing the serum composition and thus it is considered to be useful as a hair growth promoter in the future.
