Thuja orientalis extract (TOS) has been used on the hemostatic roborant, sedatives and stressless in oriental countries. We investigate the inhibitory effects on the productions of pro-inflammatory cytokines such as interleukin-1beta (IL-1β), IL-6, tumour necrosis factor alpha (TNF-α), and nitric oxide (NO) and the hair promotiont of TOS in the macrophage celline RAW264.7 or hair loss-induced DBA1J mice. T08 (50-500 ㎍/㎖) per se had no cytotoxic effect non-stimulated cells, but this extracts concentration-dependently reduced the release of NO, (IL-1β), IL-6, and TNF-α in the stimulate RAW264.7 cells with lipopolysaccharide (LPS). Moreover, when applied TOS (500 ㎍/㎖) to DBA 1J/mice, hair growth was promoted remarkably. These data suggest that T08 promotes hair growth on hair loss induced model mice and these properties may contribute to the anti- hair loss activity of the Thuja orientalis.

This paper was conducted to examine the level of total and organic mercury in the scalp hair by the consumption pattern of fish. The scalp hair samples were collected from the occipital part of 101 in coastal, 106 in rural. The total and organic mercury contents of adult scalp hair increased with age up to the forties and slightly decreased in the fifties. (p<0.01) The mercury contents of the persons who were favorite dishes of fish were most high, and who prefer fish were 2 times higher than those of the persons who prefer vegetables and broiled. The contents of total and organic mercury in scalp hair showed a increasing tendency with the intake frequency of raw and cooked fish. (p<0.01) The total and organic mercury contents in the raw fishes were over 2 times higher than those in the boiled fishes.

The fishes that are mostly used in our homes such as Pacific Mackeral, hair Tail and Alaska Pollack were devided into Freezing group, Refrigerating group and Room temperature group according to storage temperature. TVB-N, TMA-N, TMA-O and pp.H. were measured in natural state, after water washing and 3% NaCl-water washing. The results are as follows: 1. Regardless of the kinds of fishes, TVB-N in room temperature showed that rottenness first appeared after 5~8 hours in raw state, 6~12 hours in water washing, and 8~12 hours in 3% NaCl-water washing. 2. Regardless of freezing and refrigeration, Pacific Mackeral became rotten after 14 days in raw state, 14~17 days in water washing and 17 days in 3% NaCl water washing. Alaska Pollack and Hair Tail showed rottenness after 8 days in raw state, 11 days in water and 3% NaCl water washing. 3. Even in hot summer days, freshness could be preserved for 10 days if fishes were freezed ($-20^{\circ}C$) or refrigerated (4~$8^{\circ}C$) after bowel excluded, washed in NaCl water and enveloped in poly-ethylene bag.

To investigate the effects of antioxidant activities and hair loss prevention of extracts from Platycodon grandiflorum, we've prepared chloroform (CF) and ethylacetate fractions (EA) extracted from P. grandiflorum. In the results of DPPH radical scavenging assay, the two fractions showed dose-dependent antioxidant activities. Furthermore, in the ABTS assay, the two fractions exhibited the inhibitory effect over 90% at 10, 50, 100, 200 mg/mL. To investigate the inflammation inhibitory effect, we used RAW264.7 cells, these extracts were inhibited inflammatory reaction by suppressing the production of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) in dose-dependent manner. In the assay of HaCaT cells' proliferation, the 24 hr treatment of the extracts significantly accelerarted cell proliferation in the range of concentrations used. The two fractions inhibited the proliferation of Malssezia furfur, the bacteria induce the dandruff. Finally, the CF could significantly inhibit the DHT production at 1, 10, 50, $100{\mu}g/mL$, but EA showed the inhibitory effect at the concentration over $50{\mu}g/mL$. The overall results of this study suggest that the chloroform (CF) and ethylacetate fractions (EA) from P. grandiflorum could be a useful raw material for the hair loss prevention products.

This study was conducted to examine the levels of total and organic mercury in the scalp hair of the elementary school children and adults, and their relationship with the consumption pattern of fishes and shellfishes. The scalp hair samples were collected from the occipital part of 115 children and 131 adults in costal, urban and rural areas of Kyungpook province from June to August 1991. The mercury content was analysed by the atomic absorption spectrophotometer (model IL. 555) with atomic vapor accessory (model IL. 440). The total and organic mercury contents of hair were significantly higher (p<0.01) among the children who prefer fish and/or shellfish (7.728 ppm, 6.610 ppm), and canned fish and/or fish pastes (6.969 ppm, 5.885 ppm) than those who prefer meat (4.822 ppm, 3.905 ppm) and vegetables (3.974 ppm, 3.224 ppm). The children who prefer to eat the canned fish without cooking showed a higher mercury content than the children who prefer to eat it as stew or mixed with vegetables (p<0.01). There was a dose-response relationship between the intake frequency of canned fish, raw fish and cooked fish and the content of total and organic mercury of hair, the children who eat fish almost everyday showed 2 times higher than those who eat rarely (p<0.01). The mercury content in the hair of the children who eat raw fish was significantly higher than that of the children who eat boiled or broiled fish (p<0.01). The total and organic mercury contents of adult scalp hair increased with age up to the forties and slightly decreased in the fifties. The mercury contents of those who were engaged in the fishery and raw fish restaurant were 2 times higher than those of the farmers. The mercury content of the persons who were favorite dishes of fish and shellfish were most high, and who prefer raw fish were 2 times higher than those of the persons who prefer vegetables and broiled fish. The contents of total and organic mercury in adult scalp hair showed also a increasing tendency with the intake frequency of raw and cooked fish.

Free radicals are known to inhibit hair vitality by damaging the cell membranes of the hair follicles. The purpose of this study was to determine the antioxidant activities and the capacity for hair loss prevention of extracts from Platycodon grandiflorum. We prepared butanol (BF) and water (WF) fractions from P. grandiflorum. DPPH and ABTS radical scavenging activities were measured to investigate the antioxidant activities of the fractions. Both fractions exhibited dose-dependent antioxidant activities for DPPH radical production, and BF and WF almost completely suppressed ABTS radical production when supplied at 10 and 100 mg/ml, respectively. We confirmed a skin regeneration effect by treating human HaCaT skin cells with a range of BF and WF concentrations for 24 and 48 hr. The extract treatments accelerated cell proliferation. We also assayed the capacity of BF and WF to suppress inflammation using RAW264.7 cells. BF dose-dependently suppressed nitrous oxide (NO) production. Treatment of human hair follicle dermal papilla cells (HFDPC) with BF and WF promoted cell proliferation after 24, 48, and 72 hr of treatment when supplied at 10, 50, 100, and $200{\mu}g/ml$. Taken together, these results confirm the possibility of using BF and WF extracts from P. grandiflorum in formulating hair loss prevention products.

The objective of this study is to find out the effect of yeast on hair loss treatment and the role of hair follicle stem cell activator, which is important in hair growth. The authors have recently produced a substance, which has no disgusting odor, does not precipitates and does not easily corrupt, to use instead of yeast acquired from raw rice wine(Makgeolli). The substance is named Yeast Constituent Extract(YCE). In this research, the Produced YCE was applied on the hair loss area of 10 Androgenic alopecia patients, twice every day for 6 months, in order to test the effect of hair loss treatment and the role of stem cell activator. As a result, all of the patients showed a significant growth of hair after 3 months of test, and showed much more growing, thickening and strengthening of hair after 6 months. As a result of measuring the number of hair strings in the same scalp region of the patients after 6 months, it is found that the density of hair has increased, indicating that the hair loss treatment was effective. Also the hair follicle stem cell was isolated from the patients and the contents of growth factors (IGF, VEGF, FGF, HGF) derived from hair follicle stem cell were measured with ELISA. As result, the amount is found to be about 10 times greater than before the test. The hair follicle stem cell contains many growth factors that affect growth of hair, so it takes a highly important role in hair loss treatment. The YCE that the authors have produced was found to be effective in increasing the contents of growth factors that are derived from hair follicle stem cell. Thus it can be inferred that the YCE plays a role as a stem cell activator that activates the hair follicle stem cells. In conclusion, the YCE is considered to be highly effective for hair loss treatment and to have a role as a stem cell activator.
