  • In this study, the stable maintenance of bioactivity in alkaline ionized water (AIW) and antibacterial effects of AIW were evaluated to confirm benefits of AIW. As controls, purified water (PW) and tap drinking water (DW) were used. The pH and ORP (oxidation-reduction potential) of AIW, PW and DW used were 9.5 and 120 mV, 7.2 and 144 mV, and 7.3 and 564 mV, respectively. High level of minerals was observed in DW (DW>AIW>PW of mineral contents). Concentrations of $Ca^{++}$ and $Na^+$ in DW were 14.5, and 8.4 mg/l, respectively, while no $Ca^{++}$, $Mg^{++}$, $K^+$, and $Na^+$ were detected in PW. Evaluation of antioxidant activities for AIW, PW and DW showed that the waters did not act as antioxidants. However, the DPPH (1,1-diphenyl-2-picryl hydrazyl) or superoxide radical scavenging activities or reducing power of vitamin C were stably maintained in AIW and PW, though not in DW, against heat treatment ($60^{\circ}C$) or vigorous shaking (120 rpm) at $37^{\circ}C$. Similarly, after aspirin treatment at $60^{\circ}C$ for 1 hr, the antithrombosis activity in PW and AIW was 62.6% and 55.3%, while that of DW was 52.1%. Furthermore, cell growth analysis and viable cell count of Escherichia coli H7:O157 in PW, AIW and DW showed that AIW and DW, not DW, have antibacterial activities. Our results suggest that the state of water, for example pH, ORP and mineral contents of water, should be considered in medicine or food industries, and that AIW has high potential for utilization in various fields.

Inhibititory Effect of Water- or petroleum Ether-extract from Red Ginseng on Serotonin Release from Human Platelets (Comparative Study Between 6-year and 4-year Old of Red Ginseng) (사람 혈소판으로부터 serotonin 방출반응 대한 홍삼의 물 추출물 및 petroleum ether 추출물의 억제 효과)

  • It was founded that an X-compound is contained in extracts from the root of old red ginseng (6RG) compared with that from the root of 4-year old red ginseng(4RG). Both water extract and petroleum ether extract (PEII) from 6RG or 4RG inhibited the release of [$^{3}H$]-serotonin induced by platelet activating factor (PAF; 40 ng/ml). Water extract and PEll from 6RG Inhibited potently PAF-induced [$^{3}H$]-serotonin release compared with those from 4RG. X-compound out of both water extract and PEll from 6RG inhibited the release of [$^{3}H$]-serotonin inducted by collagen (100 $\mu\textrm{g}$/ml) or thrombin(20 U/ml). X-compound had a synergistic effect with water extract from 4RG on collagen-and thrombin-induced [3H] -serotonin release out of human platelets. The concentration(IC50) of X-compound that require to inhibit 50% of [$^{3}H$]-serotonin-release was 3.25 $\mu\textrm{g}$/ml, and it is inferred that maximum concentration of X-compound that inhibits the release of [$^{3}H$]-serotonin is 10 $\mu\textrm{g}$/ml. Because thrombosis is resulted mainly from the irreversible aggregations which are intimately related with the serotonin release and migraine is also caused when serotonin is released, it is inferred that water extract, PEII and X-compound from 6RG have antithrombosis and antimigrainous functions by inhibiting the release of serotonin from human platelets.

  • In recent years, the number of people suffering from depression due to hair loss has been increasing. The treatment methods such as clinical pathology and vanity surgery have been developed. There are therapies and materials for hair growth promotion and hair loss prevention. But the effectiveness of such therapies and materials is not fully evaluated and some side-effects have been reported. In this study, microneedle therapy using very thin and delicate needles promotes absorption of drug. During this therapy, the microneedle makes micro holes that help absorbion of drugs into the scalp. In this study, absorbion of fermented soybean were evaluated. The ingredient has antioxidant, antiandrogen, and antithrombosis effect for alopecia. The fermented soybean is more effective for complex hair loss when used with microneedle. It is because of the microneedle's excellent drug delivery system (DDS). This therapy that increases the absorption of fermented soybean is a very useful scalp care method which prevents, treats and controls alopecia. This microneedle therapy using fermented soybean is an advanced technology for scalp care.

  • Gardenia fructus has been reported to have bioactivities of lowering blood glucose, antitumor, antithrombosis, repression of neogenesis of blood vessels, antioxidant and antibiosis. However, the nitrite scavenging activity and utilization in meat products have not been studied. The substitution effect for nitrite and antibiosis of Gardenia fructus extract (GFE) were investigated by measuring the residual nitrite contents and storage properties of pork patties prepared with nitrite (50, 100, and 150 ppm) and GFE (0, 0.25, 0.5%). The CIE $L^*$ and CIE $a^*$ of pork patties decreased, while CIE $b^*$ increased as the addition of GFE increased. Patties with more GFE added tended to be lower in pH when stored at $4^{\circ}C$ for 6 wk, but TBARS and VBN were not affected by the addition of GFE. Residual nitrite in patties was lowered as the storage period was lengthened and as the GFE addition was increased. During the storage at $4^{\circ}C$, Escherichia coli was not detected, and the total aerobic bacterial count was decreased as more GFE was added, showing the substitution effect of GFE for nitrite in antimicrobial activity. In conclusion, the results show that GFE has nitrite scavenging and antibiotic activities in meat products, suggesting its potential use in healthy and sustainable foods with diverse biofunctionalities.
