The objectives of this study were to find out the plant to enhance immune activity among 42 kinds of foods frequently consumed by the Korean elderly consisting of 5 food groups and 5 wild plants. Each sample was assessed the immunoactive effect by measuring $NF-{\kappa}B/AP1$ gene expression, nitric oxide and cytokine production in $RAW-Blue^{TM}$ cell. Soybean sprouts of 47 plants showed the highest $NF-{\kappa}B/AP1$ gene expression at the level of $1.13{\pm}0.03$ (O.D. 650 nm) and Soritae, sweet potato, banana, apple, garlic, crown daisy, cabbage and Ailanthus altissima also had high activity of $NF-{\kappa}B/AP1$ gene in $RAW-Blue^{TM}$ cell stimulated by LPS. NO production of Ailanthus altissima was significantly higher than that of other plants and 16 plants of glutinous sorghum, black rice, Seoritae, Heuktae, sweet potato, banana, apple, garlic, mungbean sprouts, spinach, crown daisy, young pumpkin, cabbage, soybean sprouts, Actinidia arguta and Aster scaber were the next best activity. The above results selected 17 out of 47 plant samples. Moreover, soybean sprouts was significantly shown to increase $TNF-{\alpha}$ ($1,509.55{\pm}1.38pg/mL$) and $IL-1{\beta}$ ($54.56{\pm}1.08pg/mL$) cytokines in comparison with RAW-Blue cell stimulated by LPS. According to the results of in vitro evaluation, the ethanol extract of soybean sprout increased the production of immune-enhancing cytokines by proliferation of macrophages. In addition, $NF-{\kappa}B$ transcription factor activity and NO production ability were excellent, and it was selected as a material having excellent immunological activity.

A tree of Ailanthus altissima Swingle was fastened with a plastic band, 19mm wide, around the stem 180cm above ground level and was left to grow under this condition for one year, By removal of this band the tumorous tissue gradually developed and the tree bearing distinct tumorous tissue, an overgrowth surrounding the stem, was harvested two years after the band removal. For the investigation of this tumorous part and its comparison with adjacent normal parts in the anatomical features of individual elements, the tumorous part and parts directly and 40cm above and below the tumorous part were obtained from the tree. The tumor wood having remarkably wider growth increment occurred in the 3rd growth ring the first year after removal of the fastened band, and the barrier zone which delimited the discolored wood from the normal-colored wood inwards appeared u1 the intra-2nd growth ring produced during the fastened period in the tumorous part and the false ring-like zones equivalent to barrier Zone were shown in the normal-colored 2nd growth rings of the parts directly and 40cm above and below the tumorous part, as well. The tumor wood, the 3rd growth ring, and proportion of the 2nd growth ring formed after barrier zone in the tumorous part shared common characteristics in the irregular growth ring boundary, misshapen and shorter individual fibers and vessel elements, and large ray widths and heights. The springwood pores were smaller in diameter in the tumor wood, and the larger radial and smaller tangential diameters of summerwood solitary pores and individual pores consisting of pore multiples in proportion of the 2nd growth ring formed after the barrier zone were transformed into near-isodiametric in the tumor wood, the 3rd growth ring, in the tumorous part. Only in proportion of the 2nd growth ring formed after the barrier zone were transformed into near-isodiametric in the tumor wood, the 3rd growth ring, in the tumorous part, ray densities greatly increased. And the massive tumor wood was caused not by cell size but by cell number because the radial and tangential diameters of fibers in the tumor wood, the 3rd growth ring, in the tumorous part were not sufficiently different from those in the same aged growth rings of the directly and 40cm above and below the tumorous part.

Ailanthus altissima has been used to settle an upset stomach, to alleviate a fever, and as an insecticide. We reported that the water extract of A. altissima induced apoptotic cell death in HL-60 human leukemia cell line. Here, we showed the dose-dependent inhibitions of cell viability by the extract, as measured by cell morphology. The cell cycle control genes are considered to play important roles in tumorigenesis. The purpose of the present study is also to investigate the effect of A. altissima on cell cycle progression and its molecular mechanism in the cells. The level of p21 protein was increased after treatment of the extract, whereas both Bcl-2 and Bax protein levels were not changed. These results suggest that A. altissima induces apoptotic cell death via p21-dependent signaling pathway in HL-60 human leukemia cell line which delete wild type p53. G1 checkpoin related gene products tested (cyclin D3, cyclin dependent kinase 4, retinoblastoma, E2F1) were decreased in their protein levels in a dose-dependent manner after treatment of the extract. Taken together, these results indicate that the increase of apoptotic cell death by A. altissima may be due to the inhibition of cell cycle in HL-60 human leukemia cell line

Oral streptococci are major constituents of dental plaques, and their prevalence is closely linked with various pathologic symptoms, such as dental caries. To develop natural anticaries agent, we prepared 309 kinds of plant extracts from 215 species of edible or medical plants, and antibacterial activity of the extracts against Streptococcus mutans JC-2 were evaluated based on 96 well microtiter plate assay and disk paper method, subsequently. Among the tested plant extracts, Ailanthus altissima, Paeonia lactiflora, Rubus phoenicolasius, Aralia continentalis, Quercus acutissima, Persicaria hydropiper and Agrimonia pilosa extracts showed strong antimicrobial activity. Determination of minimal inhibitory concentration (MIC) of the selected seven plant extracts showed that Ailanthus altissima, Persicaria hydropiper and Quercus acutissima extracts ($MIC=25\∼30[\mu}g/ml$) has potential as a source of natural anticaries agents.
