본 연구는 백년초 분말 첨가가 아질산염의 대체를 통한 소시지의 품질 특성에 미치는 영향을 조사하기 위하여 C(아질산염 및 백년초 분말 무 첨가구), T1(0.014% 아질산염 첨가구), T2(0.014% 아질산염 + 0.5% 백년초 분말 첨가구), T3(0.014% 아질산염 + 1.0% 백년초 분말 첨가구), T4(0.5% 백년초 분말 첨가구) 및 T5(1.0% 백년초 분말 첨가구)로 처리하며 소시지를 제조하였으며 $4^{\circ}C$에서 15일간의 저장을 통하여 실험을 실시하였다. 명도를 나타내는 CIE $L^*$값은 대조구가 다른 모든 처리구들에 비해 높게 나타났으며, 적색도를 나타내는 CIE $a^*$값은 T5 처리구가 T1과 T3 처리구의 중간 값인 10.84-11.30 범위를 나타내었다(p<0.05). 황색도를 나타내는 CIE $b^*$값과 보수력 및 조직감을 나타내는 응집성, 탄력성 그리고 씹힘성은 T5 처리구에서 다른 처리구들에 비해 유의적으로 높게 조사되었다(p<0.05). 이에 반하여, 수분함량, pH 및 백색도를 나타내는 W값은 T1 처리구에서 가장 높게 나타났다. 관능적 특성에서는 T1과 T5 처리구 간 유의적인 차이가 나타나지 않았다(p>0.05). 따라서 본 실험 결과에 의하면 0.014% 아질산염의 소시지내 첨가는 1.0%의 백년초 분말로 대체시 조직감에 부정적인 영향을 주지 않으면서도 적색도를 높일 수 있는 소시지 제조가 가능할 것으로 판단되며 이를 실용화하기 위해서는 제품의 유통기한 설정에 관한 추가 연구가 필요할 것으로 사료된다.

Objectives: The aim of the experiment is to identify any anti-tumor effects of Duchesnea indica(Andr.) Focke on stomach, liver, urinary bladder, prostate and kidney cancer cells. Materials & Methods: For cancer cells, AGS stomach, Hep3B and Hep3G2 liver, HT-1197, HT-1376 urinary bladder, PC3 prostate, and A-704 kidney cancer cells, all obtained from Korean Ce 11 Line Bank, were used. The boiled extract of Duchesnea indica(Andr.) Focke (10 and 20 microliters) was injected into cultures, and the cultures were observed at 0, 6 and 12 hours, and from then on at 12 hours intervals up to 72 hours. The destruction of stomach, liver, urinary bladder, prostate and kidney cancer cells were measured through Trypan blue exclusion testing. The suppresion on viability of stomach, liver, urinary bladder, prostate and kidney cancer cells was measured via MTT assay. Anti-cancer mechanisms were assessed by analyzing the cell cycle. Results: In morphologic change, AGS, Hep3B, HepG2 showed the withdrawn and floating appearance that is typical in cellular impairment. The destruction of AGS, HT-1197, HT-1376, A-704, PC-3, Hep3B and HepG2 cancer cells in each test group was greater than that in the control group to a statistically significant degree. The suppression on viability of AGS, HT-1197 and Hep3G in each test group was greater than that in the control group to a statistically significant degree. Analysis of the cell cycle after injection of D... Focke showed inhibition of cell division in all test groups(AGS, Hep3B, HepG2, HT-1197, HT-1376, PC3, A-704). Conclusions: The results of this experiment suggest that Duchesnea indica(Andr.) Focke has statistically significant anti-tumor effects on stomach, urinary bladder, kidney, prostate and liver cancer, of which stomach and liver cancer are prominently significant. This in vitro experiment supports a role for Duchesnea indica(Andr.) Focke as a potential cancer treatment, but progressive research on Duchesnea indica(Andr.) Focke and its anti-tumor effects is needed to develop a practical application for it in cancer treatment.

This study was conducted to evaluate the drought tolerance of Japonica and Indica rice cultivars during germinating and seedling stages by using the polyethylene glycol (PEG) solution. Each 5 cultivars of Japonica and Indica were cultured from 14 days after seeding(DAS) to 21 DAS using the PEG solution in a moderate water potential (-0.63 MPa). The lengths of radicle and plumule during the germinating stage were inhibitied by the PEG treatment to about 50% and 85%, respectively. The application of PEG to the seedling of two rice types caused to inhibit the plant height and leaf age about 23 % and 10%, respectively. Shoot and root dry weights by PEG treatment were inhibited more severely in Japonica than those in Indica. The difference on delaying of leaf area expansion between both rice types was not found with treatment of PEG, while the leaf color was increased in both Japonica and Indica by 19.9% and 9.2%, respectively. The average photosynthetic ability was inhibited more in Japonica to 36.0% than did Indica to 27.9%. The stomatal conductance was severely affected by PEG treatment, and the degree was varied in both rice types, ranged with 80-85% in Japonica and 29.3-81.6% in Indica. These results indicate there is little relationship between seed germination and seedling growth under the stress of low water potential.

Fumaria indica Linn. (Syn: Fumaria parviflora, Fumariaceae) is a wildly grown weed, mentioned and recommended in classical Ayurvedic texts for treatments of variety of ailments including dermatological diseases, topical diseases, cardiovascular complaints, circulatory disease, fever and headache etc. The present pilot study was designed to experimentally verify the possibility that fumarates are the major bioactive principles of Fumaria indica extracts involved in their stress response modulating activities, and to estimate pharmacologicallyactive dose ranges of fumarates and standardized methanolic extract of Fumaria indica (MFI). Effect of single, 5 and 10 daily oral doses of pure fumaric acid (FA), monomethyl fumarate (MMF), dimethyl fumarate (DMF) and MFI was quantified in well validated rodent models viz. apomorphine induced cage climbing, stress induced hyperthermia, and elevated plus-maze tests. Obtained results reveal high efficacy of MFI and pure fumarates possess qualitatively analogous activity profiles in all the three tests. There were no significant difference in the potencies of pure FA, MMF and DMF in the three tests, whereas efficacy of MFI in the elevated plus maze test for anxiolytics was higher than in the other two tests. Efficacies of all the four test agents in all the three tests increased with increasing number of days of oral treatments. Results of these pilot experiments should be helpful for more rational selections of pharmacologically interesting dose ranges and treatment regimens of fumarates and Fumaria indica extracts for further more holistic explorations of their diverse therapeutic potentials.

Background and purpose: This study was carried out to learn more about the potential prophylactic or antibacterial activity of the plant Acalypha indica against selective pathogenic bacteria. Experimental: The test organisms were Sarcina lutea IFO 3232, Bacillus subtilis IFO 3026, Pseudomonas denitrificans, Escherichia coli IFO 3007, Klebsiella pneumoniae ATTC 10031, Xanthomonas campestris IAM 1671, and Proteus vulgaris. Leaf, stem, and bud powder of Acalypha indica were dissolved in various solvents, and the extracts were tested for antimicrobial activity through the disc diffusion method. GC-MS profiling was performed to characterize active chemical compounds in the essential oil of Acalypha indica. Results: The ethanol extract showed the highest activity against all bacteria, while the petroleum ether extract yielded the highest zone of inhibition against Proteus vulgaris ($11.83{\pm}1.75mm$). The minimum inhibitory concentration (MIC) of the ethyl acetate extract against Bacillus subtilis was 16 µg/mL. Phytochemical screening by GC-MS revealed a total of 12 bioactive compounds. Conclusion: Extracts of Acalypha indica may be useful in formulating and synthesizing new antibacterial drugs.

The plant Quisqualis indica (Compositae) has ehnopharmcological reputation of being used as a healing agent in Bangladesh. In this study, preliminary screenings were conducted to look at the antimicrobial susceptibility and cytotoxicity of the plant extract. The extractives of the plant were subjected to screening for inhibition of microbial growth by the disc diffusion method. The zones of inhibition demonstrated by the n-hexane, carbon tetrachloride, chloroform and aqueous soluble partitionates of the methanolic extract ranged from 8 - 15 mm, 8 - 18 mm, 12 - 20 mm and 10 - 16 mm, respectively at a concentration of 400 ${\mu}g$/disc. All the extractives were also subjected to brine shrimp lethality bioassay for primary cytotoxicity evaluation. Here, the carbon tetrachloride soluble materials demonstrated the highest cytotoxicity with $LC_{50}$ of 0.826 ${\mu}g$/ml, while n-hexane, chloroform and aqueous soluble partitionates of the methanolic extract revealed the $LC_{50}$ of 1.254, 3.866 and 5.366 ${\mu}g$/ml, respectively. This is the first report of the antimicrobial activity and cytotoxicity Q. indica.

The study was conducted to investigate the effect of rootstock on growth and early yield of stenting-propagated cut roses (Rosa hybrida Hort.) 'Pink Aurora' and 'Yellow King'. The scions, prepared as single-node cuttings, each with a five-leaflet leaf, were grafted onto cuttings of Rosa indica 'Major', Rosa multiflora 'Chille Wonye No. 1', Rosa multiflora 'K-1', or Rosa multiflora 'Burr' as the rootstock. The rootstock cuttings were removed of all leaves and buds before grafting. The base of scion and the top of rootstock were held together and simultaneously cut at a $45^{\circ}$ angle for ease of grafting. Scion-rootstock unions were stuck in rockwool cubes and placed on a misted glasshouse bench for rooting before being transplanted into a rockwool slabs for cultivation. Rooting was the greatest in the 'Pink Aurora' and 'Yellow King' grafted on the rootstock Rosa indica 'Major'. In 'Pink Aurora', stem length, stem diameter, five-leaflet leaves per stem, and stem fresh weight of the harvested cut flowers were not affected by the rootstock. The greatest total yield of 'Pink Aurora' was obtained in plants grafted onto the Rosa indica 'Major' rootstock. Overall growth of 'Yellow King' was the greatest in plants grafted onto Rosa multiflora 'Burr' rootstock, although total yield was not affected by the rootstock. These results suggest that Rosa indica 'Major' is the most effective rootstock not only for rooting, but also for early yield and growth for stenting propagation of these cut roses.
