The objective of the present study was to establish the method of measurement of hydrogen peroxide and to estimate the anti-oxidative effect of genistein in the skin. UVB induced skin oxidation and anti-oxidative effect of genistein formulations were evaluated by determining levels of hydrogen peroxide. The mechanism involved in the determination of hydrogen peroxide is based on a color reaction between ferric ion (Fe3＋) and xylenol orange, often called FOX assay and subsequent monitoring of... -
Comparison of the Determinants in the Differences in Force- Frequency Relationships between Rat and Rabbit Left Atria

The underlying mechanism commonly applicable for both the positive and negative force-frequency relationships (FFR) was pursued in left atria (LA) of rat and rabbit. The species differences in the roles of Na/Ca2 exchanger and sarcoplasmic reticulum (SR), which are major intracellular Ca2 regulatory mechanisms in the heart, were examined in the amplitude accommodation to the frequency that changed from 3 Hz to the variable test frequencies for 5 minutes in the electrically... -

Si의 기판상태, 불순물의 종류와 양, 어닐링온도 등을 달리하여 Ti-silicides를 형성시켰을 때 면 저항과 두께측정, 불순물들의 분포와 미세구조 관찰을 통하여 Ti-silicides 형성반응을 조사하였다. 기판상태, 불순물의 농도, 어닐링온도가 Ti-silicides 형성에 직접적으로 영향을 미쳤다. Amorphous Si 기판상에서 Ti-silicides가 형성되었을 때 <TEXT>$TiSi_2/Si$</TEXT> 계면편평도가 보다 향상되었다. Poly-Si내 불순물의 농도가 $1{ imes}10^{16}ions/cm^2$ 이상일 때 <TEXT>$TiSi_2$</TEXT> 형성이 크게... -
Synthesis and characterization of carbon doped TiO₂ photocatalysts supported on stainless steel mesh by sol-gel method

This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy... -

Shepherd’s purse, Capsella bursa-pastoris (L.) Medik., has been considered a health food for centuries in Asia and is known to contain the isothiocyanate compound sulforaphane. In this study, we evaluated the anti-inflammatory and antibacterial properties of a sulforaphane-containing solution (SCS) isolated from shepherd’s purse. SCS had significant anti-inflammatory activity indicated by the decreased levels of nitric oxide (NO), cytokines (interleukin 1β [IL-1β], IL-6, and IL-10), and... -

The fruit of the black raspberry (Rubus coreanus Miquel) has been employed in traditional medicine, and recent studies have demonstrated its measureable biological activities. However, the root of the black raspberry has not been studied. Therefore, in this study, we evaluated the anti-inflammatory and antibacterial properties of the root and unripe fruit polyphenols of the black raspberry. Both polyphenols proved to have anti-inflammatory activity as evidenced by the decreased nitric oxide... -
Carrageenan-Induced Hyperalgesia Is Partially Alleviated by Endomorphin-1 Locally Delivered into Inflamed Paws in Rat

This study was performed to test whether endomorphin-1 has analgesic effect, when locally administrated into inflamed peripheral tissue. Carrageenan suspension (0.5%) was injected intraplantarly into the right paw of Sprague-Dawley male rats, and the rats were subjected to a series of mechanical stimuli with von Frei filaments before and after the injection. Carrageenan-injected rats showed typical inflammatory hyperalgesic signs and decrease of withdrawal threshold, peaked at 3 to 6 hours after...
