The present study was to evaluate effects of vitamin E on intravenous administration of lidocaine-induced antinociception. Experiments were carried out using male Sprague-Dawley rats. Orofacial formalin-induced nociceptive behavioral responses were used as the orofacial animal pain model. Subcutaneous injection of formalin produced significant nociceptive scratching behavior. Intraperitoneal injection of 5 and 10 mg/kg of lidocaine attenuated formalin-induced nociceptive behavior in the 2nd phase, compared to the vehicle-treated group. Intraperitoneal injection of 1 g/kg of vitamin E also attenuated the formalin-induced nociceptive behavior in the 2nd phase, compared to the vehicle-treated group. However, low dose of vitamin E (0.5 g/kg) did not affect the nociceptive behavioral responses produced by subcutaneous injection of formalin. The present study also investigated effects of intraperitoneal injection of both vitamin E and lidocaine on orofacial formalin-induced behavioral responses. Vehicle treatment affected neither formalin-induced behavioral responses nor lidocaineinduced antinociceptive effects. However, intraperitoneal injection of 0.5 g/kg of vitamin E enhanced the lidocaineinduced antinociceptive effects in the 2nd phase compared to the vehicle-treated group. Intraperitoneal injection of naloxone, an opioid receptor antagonist, did not affect antinociception produced by intraperitoneal injections of both vitamin E and lidocaine. These results suggest that treatment with vitamin E enhances the systemic treatment with lidocaine-induced antinociception and reduces side effects when systemically treated with lidocaine. Therefore, the combined treatment with vitamin E and lidocaine is a potential therapeutic for chronic orofacial pain.

본 연구에서는 녹차, 삼백초, 귀룽나무 등을 포함한 식물성 추출물의 샴푸로서의 특성에 대해 연구하였다. 녹차와 삼백초의 잎은 열수추출 후 동결건조하여 유효성분을 획득하였으며, 귀룽나무 줄기는 숙성과정을 거쳐 열수 추출 후 역삼투 및 초음파 추출로 유효성분을 획득하였다. 식물성 추출물을 함유한 샴푸, 계면활성제(Sodium dodecylsulfate,Quillaja Bark Saponin)와 피마자유 간의 계면장력을 측정한 결과, 샴푸의 계면장력은 저농도에서는 SDS와 QBS보다 낮았으나, 100% 원액에서는 대조군과 유사한 계면장력을 나타내었다. 식물성 추출물을 함유한 샴푸는 황색포도상구균과 칸디다균에 대해서는 약간의 항균력을 보였다. 식물성 추출물의 세포독성시험(MTT assay) 결과, 100~350 μg/ml 범위의 농도에서는 80% 이상의 세포생존율을 보였으나 그 이상의 농도에서는 세포독성을 나타내었다. 식물성 추출물을 함유한 샴푸의 시간변화에 따른 장기 안정성 시험결과, 제조 후 초기 3개월은 pH, 점도, 외관의 변화가 안정적이었으나 그 이후 상온이 높아짐에 따라 pH와 점도의 변화가 심하여 제형의 보완이 필요한 것으로 나타났다. 따라서 샴푸의 제형을 다소 개선한다면 녹차, 삼백초, 귀룽나무 등을 함유한 식물성 추출물은 샴푸로의 사용 시 높은 가능성을 보였다. In this research, botanical extracts containing green tea, Saururus chinensis and Prunus padus were tested to see possibility as shampoo. Leaves of Green tea and Saururus chinensis were extracted with hot water. Prunus padus bark extract was applied reverse osmosis and ultrasonic extraction. When interfacial tension was measured among shampoo including botanical extracts, Sodium dodecylsulfate(SDS) and Quillaja Bark Saponin(QBS), that of shampoo was lower than that of SDS and QBS at lower concentration, however, it showed similar interfacial tension at 100% concentration. Shampoo showed moderate antimicrobial activity in Staphylococcus aureus and Candida albicans. Botanical extract did not indicate cell toxicity up to 350 μg/ml concentration in MTT assay. Shampoo containing botanical extract was stable for 3 months, however, it showed considerable variation in pH and viscosity. In conclusion, shampoo containing botanical extract shows strong possibility for natural shampoo if the formulation is modified.

The aims of this study were to investigate some macrominerals (Na, Ca, P, K, Mg) in 207 beverages, 19 liquid teas, and 24 liquid coffees. The samples were digested by microwave and determinations of macrominerals were carried out by an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). The elements, listed in order of mean value of macromineral content, were potassium 208.4±298.2 mg/L (72.2±169.8 mg/container)> calcium 89.0±161.0 mg/L (26.0±57.7 mg/container)> sodium 71.2±75.0 mg/L (20.9±27.9 mg/container)> phosphorus 55.6±91.9 mg/L (17.9±33.8 mg/container)> magnesium 6.1±18.4 mg/L (2.4±10.1 mg/container). All 250 samples contained sodium and potassium, and the detection rate of calcium, phosphorus and magnesium was 88.4%, 93.2%, and 20.4%. The mean ratio of phosphorus to calcium in beverages, liquid teas, and liquid coffees was 4.2±16.0 (ND~164.4), and sports drinks showed the highest mean ratio (48.5±75.6) significantly (p<0.05). In case of sodium, detected content exceeding labeling regulations (less then 120%) was observed in 12 samples (5.5%).

본 연구에서는 황벽나무, 두충나무 등을 포함하는 복합수목추출물의 항균활성 효과 및 안전성에 대해 검토하였다. 항균활성은 피부상재균이며 기회 병원성균인 Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli 및 Candida albicans에 대해 disc 확산법으로 실험되었다. 안전성 시험으로는 단회 경구투여 독성시험, 단회투여 흡입독성 시험, 반복투여 흡입독성시험이 실시되었다. 항균력효과시험 결과 추출물은 Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans에 대해 우수한 항균활성을 보여주었으나, Escherichia coli에서는 항균활성이 없었다. 복합수목추출물의 단회 경구투여 독성시험, 단회투여 흡입독성시험 및 반복투여 흡입독성시험의 결과 독성은 관찰되지 않았다. 따라서 황벽나무, 두충나무 등을 포함한 복합수목추출물은 천연 항살균제로서 상업화 가능성이 매우 높음을 알 수 있었다. In this study, mixed plant extracts including Phellodendro namurense and Eucommia ulmides Oliv were tested for antimicrobial activity and safety. Antimicrobial activity was measured by disc diffusion method using normal skin flora and opportunistic microbes such as Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans. As safety test, single dose oral toxicity test, single dose inhalation toxicity test and repeat dose inhalation toxicity test were done. From antimicrobial test, plant extracts showed significant antimicrobial activity Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, however, did not indicate any antibacterial effect on Escherichia coli. From 3 kinds of safety tests, toxicity of mixed plant extracts was not observed. From experimental results, mixed plant extracts including Phellodendro namurense and Eucommia ulmides Oliv showed good potential for natural antimicrobial agent.

We investigated whether deficiency of inducible nitric oxide synthase (iNOS) could prevent isoproterenol-induced cardiac hypertrophy in iNOS knockout (KO) mice. Isoproterenol was continuously infused subcutaneously (15 mg/kg/day) using an osmotic minipump. Isoproterenol reduced body weight and fat mass in both iNOS KO and wild-type mice compared with saline-infused wild-type mice. Isoproterenol increased the heart weight in both iNOS KO and wild-type mice but there was no difference between iNOS KO and wild-type mice. Posterior wall thickness of left ventricle showed the same tendency with heart weight. Protein level of iNOS in the left ventricle was increased in isoproterenol-infused wild-type mice. The gene expression of interleukin-6 (IL-6) and transforming growth factor-Ղ (TGF-Ղ) in isoproterenol-infused wild-type was measured at 2, 4, 24, and 48-hour and isoproterenol increased both IL-6 (2, 4, 24, and 48-hour) and TGF-Ղ (4 and 24-hour). Isoproterenol infusion for 7 days increased the mRNA level of IL-6 and TGF-Ղ in iNOS KO mice, whereas the gene expression in wild-type mice was not increased. Phosphorylated form of extracellular signal-regulated kinases (pERK) was also increased by isoproterenol at 2 and 4-hour but was not increased at 7 days after infusion in wild-type mice. However, the increased pERK level in iNOS KO mice was maintained even at 7 days after isoproterenol infusion. These results suggest that deficiency of iNOS does not prevent isoproterenol- induced cardiac hypertrophy and may have potentially harmful effects on cardiac hypertrophy.
