Volatile components of Cornsilk(Zea mays L.) were isolated by purge and trap headspace method and were analyzed by GC and GC/MSD. A total of 44 components were identified in the cornsilk volatile coponents including 9 alcohols 7 aldehydes and ketones 14 terpenes and terpene alcohols 3 pyrazines 5 hydrocarbons and 6 miscellaneous components. The major components were 2-propanol(8.08%) pen-tanol(1.82%) hexanol(2.86%) hexanal(3.68%) heptanal(7.40%) nonanal(7.93%) decanal (2.04%) $\alpha$-copaene(2.20%) limonene(1.68%) $\alpha$-selinene(1.03%) $\beta$-selinene(1.03%)

국내에서 재배되는 옥수수의 수확 후 버려지는 잎을 수거하여 음건하고 분쇄 한 후 실험에 사용하였다. 두 가지 용매로 추출 후 DPPH, ABTS, 총 플라보노이드 함량, 총 폴리페놀 함량을 측정하여 항산화 활성을 분석하고, Paper disc diffusion method 로 clear zone의 직경을 측정 하였다. 그 결과 에탄올 추출물이 모든 항산화활성과 항균활성에서 다소 높은 결과를 나타내었다. Gallic acid를 표준물질로 하여 총 polyphenol 함량을 측정한 결과 CE는 $31.2{\pm}5.2mg\;GAE/g$로 높은 활성을 보였고, DPPH radical 소거능 측정 결과 CE는 1, 10, 100, 1,000 (${\mu}g/mL$) 농도에서 각각 $4.6{\pm}0.9%$, $6.4{\pm}0.5%$, $22.9{\pm}0.6%$, $83.2{\pm}0.2%$로 나타나 농도 의존적 경향을 보였으며 1,000 (${\mu}g/mL$)에서는 매우 높은 활성을 보였다. 지금까지 옥수수와 옥수수 수염에 대한 연구는 많지만 페기 되는 잎에 대한 연구는 없어 본 연구가 새로운 천연 항산화, 항균 효능을 가진 원료개발의 기초 자료가 될 것으로 판단된다.

The growth characteristics and yield per unit area of two cultivation systems of forage, corn (Zea mays L.) monoculture and corn-cowpea (Vigna sinesis King) inter-cropping were compared and obtained follow results. 1. The two cultivation systems were not significantly different in leaf length, leaf width and length of internode with harvesting time. 2. The weight of stalk and leaves of a plant were decreased with maturity, while weight of ear was markedly increased. The patterns of relative ratio of each components was essentially same in each cultivation system. In corn monocrop., the percentages of stalk, leaf and ear at final harvesting stage were 22.9, 13.7 and 63.4, respectively. 3. Dry matter yield per unit area (33kgIlOa) of intercropped corn at yellow stage was similar to that of monocropped corn ( l,482.8kg/ 10a vs 1 ,SO8.9kg/ 10a). At ripe stage, however, the DM yield of intercrop. was higher than that of monocrop. (1,810.4kg/lOa vs 1,660.4 kg/ 1 Oa). 4. The same pattern was observed in organic matter yield.

Objectives: Toxoplasmosis is a worldwide health problem that caused by intracellular apicomplexan parasite, Toxoplasma gondii (T. gondii). Considering that the available drugs for toxoplasmosis have serious host toxicity, the aim of the current study was to survey the in vitro and in vivo anti-Toxoplasma activity of Zea mays (Z. mays) and Eryngium caucasicum (E. caucasicum) extracts. Methods: Four concentrations (5, 10, 25, and $50mg\;mL^{-1}$) of Z. mays and E. caucasicum methanolic extracts for 30, 60, 120, and 180 min were incubated with infected macrophages and then the viability of RH strain of T. gondii tachyzoites was evaluated by trypan blue staining method. Also, we evaluated the survival rate of acutely infected mice with the extracts (100 and $200mg\;kg^{-1}\;day^{-1}$) intraperitoneally for 5 days after infection with $2{\times}104$ tachyzoites of T. gondii. Results: The anti-Toxoplasma effect of the methanolic extracts were extremely significant compared to the negative control group in all exposure times (P < 0.05). The Z. mays (10, 25 and $50mg\;mL^{-1}$) killed 100% of the parasites after 180 and 120 min exposure, respectively. Also, high toxoplasmacidal activity was observed with E. caucasicum extract. Furthermore, treatment of experimentally infected mice with the Z. mays (100, $200mg\;kg^{-1}\;day^{-1}$) and E. caucasicum ($100mg\;kg^{-1}\;day^{-1}$) significantly increased their survival rate compared to untreated infected control (P < 0.05). Conclusion: These extracts are promising candidates for further medicine development on toxoplasmosis. However, further investigations are necessary to clarify effective fractions of the Z. mays and E. caucasicum extracts and the mechanisms of action.

Purpose: This study intended to analyze the validity of clinical effectiveness data of clinical trials testing systemic titrated extract of Zea Mays L. unsaponifiable fraction chemotherapeutic agent. Material and Methods: Among 5 clinical trials claimed as proof of clinical effectiveness on the Web site of the manufacturer of this chemotherapeutic agent, a review of 4 clinical trials, written in either Korean or English, was conducted. Data were extracted from studies for the following variables: year of publication, age, sample size, follow-up period, combination with contemporary periodontal treatments, randomization, randomization check, blinded measurement, and statistical test type. Results: The study subjects' age intervals were too diverse to decide a common target population to generalize the findings. No study stated clearly the rationale for the sample size determination. Follow-up period to observe the start of clinical effectiveness was inconsistent and decided without any rationale of pathophysiological latent period. Randomization to make the comparisons on the same start line was performed but failed in a study. Randomization effect was not checked in 4 studies. Performance of blinded measurement of clinical outcomes to prevent bias was unclear in 2 studies. Type of statistical test was inappropriate in 3 studies. Conclusions: Based on the analysis of the validity of data on clinical and demographic variables, the four available clinical trials have not demonstrated compelling evidence of therapeutic effectiveness of systemic titrated extract of Zea Mays L. unsaponifiable fraction chemotherapeutic agent to improve prognosis of periodontal disease either with the contemporary periodontal treatment or without it.

Glycine max Merr., Zea mays L.의 엽육세포와 근단세포에서 cytolysome의 기원과 기능에 관하여 추구하였다. Cytolysomes은 원형질막과 세포질의 소포체에서 유래되는데, 원형질막의 함입으로 다소포체인 것과 환상인 다층막성구조로 분화되는 두가지 기본형이 있고, 또 세포질에서는 무과입성 소포체가 세포질의 일부를 분리시키으로서 세포질분리체로 분화된다. 원형질막과 세포질에서 유래된 이들 구조는 각각 막성구조가 증가되면서 액포내로 유리되고 자식성소화과정을 밟아 퇴화되는것 같다.
