The purpose of this study was to examine the inhibition effect of Zizania latifolia that has been used heart disease, Diabetes Mellitus and Skin disease for a long time on apoptosis induced by $H_2O_2$ in Neuro2A cell. Neuro2A cells were cultivated in RPMI(GibcoBRL) with $5\%$, FBS and treated with $H_2O_2$, and Zizania latifolia. We measured the cell viability and analyzed DNA fragmentation. Activity of PARP, Cytochrome C, caspase-9, caspase-3, p53, p21, Bax and Bcl-2 in the cell was examined by using western blot. The cell viability in Zizania latifolia treatment (60ug/ml<) decreased significantly compared with that of none treatment. (p<0.001) Zizania latifolia increased cell viability about twice as much as that being injury by $H_2O_2$. (Zizania Latifolia 20ug/ml, $H_2O_2$ 200uM, P<0.001) DNA fragmentation developed by $H_2O_2$, but was not developed in Zizania latifolia treatment. PARP, Cytochrome C, caspase-9 and caspase-3 activated all by $H_2O_2$ but were not activated in Zizania latifolia treatment.. P53, P2l and Bu activated by $H_2O_2$, and Bcl-2 got into inactivation. But the opposite results appeared in Zizania latifolia treatment. In conclusion, these results suggest that Zizania latifolia inhibit the development of DNA fragmentation and apoptosis by $H_2O_2$ and the antioxidant action of Zizania latifolia is effective. More researches about effect of Zizania latifolia are considered to need.

The purpose of this study is to investigate the proper dyeing condition, color fastness and functionality of silk fabrics dyed with Zizania latifolia Turcz. FT-IR spectrum analysis suggests that colorants of Zizania latifolia Turcz. are tannins. The dyeing of the silk fabrics using Zizania latifolia Turcz. was very good even without pretreatment or mordanting treatment. Optimal dyeing conditions of silk fabrics were colorant concentration of 200%(o.w.f.), dyeing temperature of $100^{\circ}C$, dyeing time of 60 minutes and dyebath pH of 5.5. Color fastness of dyed silk fabrics to washing, rubbing, perspiration and light was 4~4-5, 5, 4~4-5(acidic), 4-5(alkaline) and 2 respectively. UV protection rate and deodorization rate of silk fabrics dyed with Zizania latifolia Turcz. were improved. Reduction rate(Staphyloccus aureus) of silk fabrics was excellent at 98.3%. As a result, it was confirmed that the Zizania latifolia Turcz. could be used as an eco-friendly functional natural dye.

This study investigated the proper dyeing conditions, color fastness and functionality of wool fabrics dyed with Zizania latifolia Turcz. We also tried to improve light fastness through treatment with benzophenone ultraviolet absorber. The dyeing of wool fabrics using Zizania latifolia Turcz was good even without pretreatment or mordanting treatment. Optimal wool fabric dyeing conditions were colorant concentration of 200% (o.w.f.), dyeing temperature of $100^{\circ}C$, dyeing time of 80 minutes and a dye bath pH of 3. Color fastness of dyed wool fabrics to washing, rubbing, perspiration and light was 4-5, 5, 4-4-5 (acidic), 4-5 (alkaline) and 2 respectively. The results after treatment with ultraviolet absorber for improving the fastness of daylight were improved to 3-4 grade. The UV protection rate were increased after dyeing and the deodorization of ammonia gas improved to 98%. Bacterial reduction rate (Staphylococcus aureus) of wool fabrics was excellent at 99.9%. All dye fastness (except for light fastness) was excellent; in addition, the functionality of wool fabrics dyed with Zizania latifolia Turcz also improved. The results are expected to be applied to various fields because they indicate excellent results after treatment with ultraviolet absorber for improving the fastness of daylight.

팔당호 연안대에서 수심에 따른 줄(Zizania latifolia) 개체군의 저토 환경, 경엽부의 밀도, 높이 및 현존량을 조사하였다. 저토의 pH, 유기물함량, 총질소량, 유호태 인량 및 치환성 칼륨량은 수심에 따른 유의한 차이가 없었으나, 모래 함량은 수심이 깊을수록 적었다. 줄 경엽부의 밀도는 수심이 깊을수록 경엽부의 키가 높았고 경엽무 하나의 건물량과 단위면적당 현존량이 많았다. 경엽무 높이의 빈도분포는 줄이 생장함에 따라서 J자형과 첨두형으로 변하였으며, 높이의 불균등도는 감소하였는데, 그 변화는 수심이 깊은 곳에서 보다 빨리 일어났다. 따라서 줄은 수심이 깊을수록 경엽부의 밀도가 낮아지고, 그 높이와 현존량이 증가하여 수면 위로 경엽부를 돌출시키는 생장전략을 가지는 것으로 해석된다.

This study examined the changes of water quality in relation to distribution of hydrophytes, and the purification capacity of Zizania latifolia to improve the effluent from Munpyeong stream from March 1997 to December 1999. While the concentration of nitrogen and phosphorous in water were increased during the farming season, those decreased, during the streaming down to paddy and drainage areas. In investigated sites, the Z. latifolia was dominant community according to the development of the natural wetlands. Furthermore, it formed a large community owing to its high adaptability to environmental changes in the agriculture lands. In September, the leaves productivity of the Z. latifolia were 4,032g D.W/$m^2$and roots were 7,680gD.W/$m^2$. The purification capacity of the Z. latifolia for NH$_3$-N, $No_3$-N, and PO$_4$-P were 13.41, 17.07, and 4.58 respectively during 5 days. The results suggested that it needs to establish wetlands vegetated by hydrophytes to improve the water quality of the effluent from agricultural lands.

This study examined the pretreatment effect, appropriate dyeing conditions, color fastness and functionality of cotton fabrics dyed with Zizania latifolia Turcz. Dye uptake was substantially increased by pretreatment and chitosan pretreatment was much more effective than tannic acid pretreatment. Optimal dyeing conditions were colorant concentration of 100%, dyeing temperature of $100^{\circ}C$, dyeing time of 80 minutes and dyebath pH of 5.5. Color fastness of chitosan pretreatment and dyed cotton to washing, rubbing, perspiration and light was 4, 5, 3-4(acidic), 3(alkaline) and 3 respectively. Color fastness of tannic acid pretreatment and dyed cotton to washing, rubbing, perspiration and light was 4, 5, 3-4(acidic), 4-5(alkaline) and 4 respectively. Deodorization rates of ammonia(NH3) were 99.9% in both cases. UV protection rate were 98.3% of UV-A and 98.5% of UV-B in case of chitosan pretreatment. UV protection rate were 98.2% of UV-A and 98.5% of UV-B in case of tannic acid pretreatment. UV protection factor(UPF) was 50+ in both cases. Reduction rate of Staphyloccus aureus were 99.9% in both cases. Therefore Zizania latifolia Turcz. could be used a new functional colorant.
