Contact dermatitis is induced by allergy response from a lot of chemical substances brought on by environmental contamination. In this study, we investigated allergy prevention effect of baicalein which is Scutellaria radix extract. Scutellaria radix is the dried roots of Scutellaria baicalensis Georgi (Labiatae). It has been used in oriental traditional medicine for treatment of fever, diarrhea and inflammation. We have induced allergy by PCL after oral administration of 0 mg/kg, 50 mg/kg or 100 mg/kg baicalein dose for 8 times during 8 days in BALB/c mice and measured ear thickness, IgE level, histamine level, mast cell number and histopathological changes. The ear thickness of the 100 mg/kg baicalein group was thinner than that of the 0 mg/kg baicalein group. IgE level and histamine level of the 100 mg/kg baicalein group were lower than those of 0 mg/kg baicalein group. The number of mast cells of 0 mg/kg baicalein group more than that of 100 mg/kg baicalein group in the ear tissue. In addition, intradermal edema with prominent inflammatory cell infiltration was observed at 0 mg/kg baicalein group more than 100 mg/kg baicalein group in the ear tissue. These results suggest that baicalein has allergy prevention effect in BALB/c mice.

The study has been carried out to investigate of the Allergic Rhinitis by referring to 87 literatures. The results were as follows; 1. In oriental medical science, Allergic Rhinitis is belong to the category of the 'BiGu'(鼻구) 'GuChe'(구체). The 'Gu'(구) of the BiGu means watery rhinorrhea, the 'Che'(체) of the GuChe means sneezing. 2. The cause of a disease summarize the weak of Lung, Spleen and Kidney, and invasion into the nasal cavity of PoongHan etc a wrong air. Sometimes the pathologial change appear PoongHan changeHwa(風寒化火), HwaYeol is hidden in the inside(火熱內伏). The contributing factors are found a season(spring, winter), an abnormal weather(運氣 : 少陰 少陽 陽明 司天, 歲金不及), an emotional stress, an external wound of the harmful air, a food allergens and fatigue, a contact of substances, a sunlight etc. 3. Predominant symptoms are watery rhinorrhea, sneezing and nasal obstruction. Sometimes accompanic symptoms are nasal bleeding, mucopurulent rhinorrhea, olfactory disturbance, nasal polyp, rhinolalia clausa, respiratory disfunction etc. 4. The treatment-methodes is as follows, OnBoPaeJang GeoPoongSanHan(溫補肺臟 祛風散寒), GeonBilkGi(健脾益氣), BoSinNabGi (補腎納氣). The treatmentherbs is as follows, OnBoJiLuDan GaGam(溫補止流丹 加減), OkByeongPoongSan plus ChangIJaSan GaGam(玉屛風散合 蒼耳子散 加減), BoJungIkGiTang GaGam plus SoCheongLyongTang(補中益氣湯加減 配合 小靑龍湯), SinGiHwan GaGam(腎氣丸加減), GaeJiTang(桂枝湯) etc. 5. The external treatment is as follows, JeokBi(滴鼻), ChuiBi(吹鼻), SaekBi(塞鼻), stick and herbs-injection on the acupuncture-point, pressure ear acupuncture-point, herbs-pillow etc. 6. The acupuncture-moxa treatment is as follows, the methodes of cure apply TongJoGyeongGi(通調經氣), SanTongBiGui(宣通鼻竅) etc. Predominent acupuncture-points are YoungHyang(迎香), InDang(印堂), BiTong(鼻通), SangSeong(上星), HabGok(合谷) and so on. As mentioned above, from now on, it's need to the oriental medical scientific study of the Immunity and Allergy and to the external treatment's application for the ascent of the treatment-effect of the allergic disease.

The Dissolved Organic Carbon (DOC) existing in a water includes both hydrophobic and hydrophilic substances however, most of the discussion focuses on hydrophobic substances. The hydrophobic fraction was easily removed by absorption or coagulation more than hydrophilic fraction. Therefore, control of the hydrophilic fraction is very important in water treatment process. This study is to determine the variation of DOC, the removal efficiency of DOC, and Trihalomethane formation potential (THMFP) after each stage of water treatment process by fractionating Natural Organic Matters (NOM) into hydrophobic and hydrophilic substance. DOC from raw water was fractionated at acidic pH (pH<2) using XAD 8 resin column, into two fraction : hydrophobic substance (i.e. humic substance) adsorbed on XAD 8 and hydrophilic substance which represent the organics contained in the final effluent. THMFP was carried out according to the following set condition: Cl2/DOC=4 mg/mg, incubation at $25^{\circ}C$ in darkness, pH 7 adjust with HCl or NaOH as necessary, and 72hour-contact time. THMs analyzed in this study were chloroform, bromodichloromethane, dibromochloromethan, and bromoform. Sewage was almost evenly split between the hydrophobic (56%) and hydrophilic fraction (44%). But, Aldrich humic substance (AHS) was found to contain less hydrophilics (14%) than hydrophobics (86%). The formation of THMs may depend on the source which is characterized by the composition of organic matters such as AHS and sewage. The THMFP yield of sewage and AHS were assessed as follows. The value of the THMFP reaction yield, AHS $172.65{\mu}g/mg$, is much higher than that of sewage $41.68{\mu}g/mg$. This illustrates possible significant difference in THMFP according to the component type and the proportion of organic matter existing in water source. Apparently AHS react with chlorine to produce more THMFP than do the smaller molecules found in sewage. Water treatment process may reduce THMFP, nevertheless residual DOC (the more hydrophilic substance) has significant THMFP. Further reduction in organic halide precursors requires application of alternative treatment techniques.
