In this study, the immuno-enhancing activity of seed extracts were studied on the macrophage cell lines. We examined the effect of nine seed extracts on nitric oxide (NO) production in RAW 264.7 cells and selected four highly-effective seed candidates (Fagopyrum esculentum, Taraxacum platycarpum, Impatiens balsamina, Helianthus annuus) for further immune-related studies. The effects of the four seed extracts on the production of immune-related cytokines in the RAW 264.7 macrophage cell line and proliferation of Molt-4 as a T cell line were investigated. The secretion of NO from the RAW 264.7 cells was increased up to 39 ${\mu}M$ by adding the seed extracts (25 ${\mu}g/mL$) compared to the control. Also, the secretion of tumor necrosis factor-alpha (TNF-${\alpha}$) was also increased up to 32 times by adding the seed extracts (25 ${\mu}g/mL$). Secretion of cytokines such as interleukin-1 beta (IL-$1{\beta}$), interleukin-6 (IL-6), and interleukin-10 (IL-10) was also increased and induced the proliferation of T cells compared to the control. In conclusion, these results suggest that four seed extracts provide beneficial immuno-enhancing effects for human health.

The vascular flora of Dalmasan and its adjacent regions, located in Haenam-gun, Jellanam-do, is surveyed from Mar. to Oct. 2005. The number of the vascular plant taxa based on voucher specimens is 545 total which belongs to 112 families, 322 genera, 473 species, 3 subspecies, 60 varieties and 9 forms respectively. Among them, 12 taxa of Korean endemics and 4 taxa of rare and endangered plants were investigated in addition to 86 taxa of specially designated plants announced by the Ministry of Environment. A unrecorded taxon, Stellaria neglecta Weihe, is also collected in this area. Furthermore, The habitat of 5 taxa such as Asplenium trichomanes L., Asplenium wilfordii Mett. ex Kuhn, Miscanthus sinensis var. chejuensis Y.N.Lee, Impatiens kojeensisi Y.N.Lee and Digitaria violascens var. intersita Ohwi were newly added to the flora of korea, and 29 taxa of induced and naturalized plants were observed in this area.
