본 연구는 기능성 식품의 개발을 위해 갈색거저리 유충 유래 추출물에서 새로운 생리활성 펩타이드를 확인하는 것이다. 동결건조된 T. molitor 유충에서 다양한 용매로 시간에 따라 추출하였다. T. molitor 유충 추출 결과 물 추출물에서 5시간과 10시간에서 총 단백질과 고형분 함량당 각각 가장 높은 2,2,1-diphenyl-1-picrylhydrazyl (DPPH) 활성을 보였다. 물 추출물을 메탄올 농도에 따라 분획하였을 때, 높은 메탄올 농도는 상등액 중에 고분자량 단백질의 수준을 감소시키는 반면, 상등액의 DPPH 활성 수준을 증가시켜 저분자량 펩타이드가 항산화 활성을 매개하는 것으로 나타났다. 유기용매 분배에서 부탄올을 제외한 유기 용매 분배에서 물층에서 유사한 활성을 보였다. 유기용매분획물을 열처리 후 활성이 28~44% 감소하여 열에 대한 불안정한 성분이 존재하는 것으로 추정되었다. 물 추출물에 프로테아제 K를 첨가하면 DPPH 활성이 10~20% 증가하여 전체 단백질에서 방출되는 펩타이드가 항산화 활성을 부분적으로 증가시켰음을 알 수 있다. 그러므로, T. molitor 유충 추출물은 항산화제로써 기능을 수행할 수 있는 물질이 존재하는 것으로 제의할 수 있다.

Subendothelial accumulation of foam cells plays a key role in the initiation of atherosclerosis. These foam cells accumulate in fatty streaks that evolve to more complex fibrofatty or atheromatous plaques. Oxidized LDL may also be involved in atherogenesis by inducing smooth muscle cell proliferation and smooth muscle foam cell generation. (omitted)

The superoxide dismutase (SOD) mimetic activity of copper complex of 3,5-disopropylsalicylic acid (Cu(II)-DIPS) was tested and compared to those of human recombinant SOD (hrSOD) and its conjugate form with polyethyleneglycol (PEG) using fer- ricytochrome c reduction assay. Stability constant of Cu(II)-DIPS was measured po- tentiometrically using SCOGS2 program. In the presence of 10 g/L albumin, Cu(II)-DIPS lost most of its SOD mimetic activity. HrSOD was modified with polyethylene glycol (PEG) of M.W. 5000. These conjugates have markedly prolonged plasma half-lives of enzymatic activity (15.5 hr) compared to native hrSOD (5 min). In summary, efficient SOD mimetics should be stable enough not to dissociate in blood by serum protein. HrSOD could have longer half-life by conjugation with inert PEG for sustained SOD effect.

Immunometabolism, defined as the interaction of metabolic pathways with the immune system, influences the pathogenesis of metabolic diseases. Metformin and carbon monoxide (CO) are two pharmacological agents known to ameliorate metabolic disorders. There are notable similarities and differences in the reported effects of metformin and CO on immunometabolism. Metformin, an anti-diabetes drug, has positive effects on metabolism and can exert anti-inflammatory and anti-cancer effects via adenosine monophosphate-activated protein kinase (AMPK)-dependent and AMPK-independent mechanisms. CO, an endogenous product of heme oxygenase-1 (HO-1), can exert anti-inflammatory and antioxidant effects at low concentration. CO can confer cytoprotection in metabolic disorders and cancer via selective activation of the protein kinase R-like endoplasmic reticulum (ER) kinase (PERK) pathway. Both metformin and CO can induce mitochondrial stress to produce a mild elevation of mitochondrial ROS (mtROS) by distinct mechanisms. Metformin inhibits complex I of the mitochondrial electron transport chain (ETC), while CO inhibits ETC complex IV. Both metformin and CO can differentially induce several protein factors, including fibroblast growth factor 21 (FGF21) and sestrin2 (SESN2), which maintain metabolic homeostasis; nuclear factor erythroid 2-related factor 2 (Nrf2), a master regulator of the antioxidant response; and REDD1, which exhibits an anticancer effect. However, metformin and CO regulate these effects via different pathways. Metformin stimulates p53- and AMPK-dependent pathways whereas CO can selectively trigger the PERK-dependent signaling pathway. Although further studies are needed to identify the mechanistic differences between metformin and CO, pharmacological application of these agents may represent useful strategies to ameliorate metabolic diseases associated with altered immunometabolism.

Objectives : This study was conducted to determine if Scutellaria baicalensis can be used in cosmetic emulsion cream for patients with atopic dermatitis. Methods : Scutellaria baicalensis extract was obtained with the use of butylene glycol through the pressurized solvent extraction(PSE). The antioxidative activity was assessed through SOD-like activity measurement and skin irritating potential was tested using human patch test. Antimicrobial activity was measured by the clear zone formed against Staphylococcus aureus and Escherichia coli and the rheological effects on the emulsion creams were examined using oscillation test. Results : The SOD-like activity increased dose-dependently and was about 90% at 1,000ppm of Scutellaria baicalesis extract. And Scutellaria baicalensis extract did not show any potential to be irritating to the human skin, but it could not be used as an antimicrobial agent for its poor antimicrobial activity against Staphylococcus aureus. The complex modulus decreased by 1,000 pascals and the loss angle also decreased by 20% with the addition of Scutellaria baicalensis extract into the cosmetic emulsion creams, that is, the extract can confer more elastic property on the vehicle. Conclusion : From those results, Scutellaria baicalensis extract can be effectively used as an antioxidant and reinforces the elastic skincare film formed by the application of cream for patients with atopic dermatitis.
