  • The potential allergenicity of the transgene products in genetically modified organisms (GMOs), has been an important issue. As a part of the risk assessment of GMOs, we investigated the physicochemical stability and the immunogenicity of food allergens to determine their allergenicity.(omitted)

  • We investigated the mechanism of immunomodulatory action of polysaccharide isolated from cell culture of Acanthopanax senticosus (ASP). ASP was found to increase directly proliferation and differentiation of B cells, and cytokine production of macrophages, but not proliferation and cytokine production of T cells.(omitted)

  • We have measured the excited Xe atoms density in the $1s_5$ metastable states by laser absorption spectroscopy in accordance with various barrier ribs. In this experiment, the average density of one cell in the panel with stripe barrier rib has been measured to be $1.8{\times}10^{12}cm^{-3}$. The panel with close type barrier rib has been measured to be $5.1{\times}10^{12}cm^{-3}$.

  • Petiole explants from 20 cultivars of Catharanthus roseus were cultured on various shoot-inducing media to assess their competence for adventitious shoot formation. After eight weeks of culture on Murashige and Skoog' s medium supplemented with 4.4 $\mu\textrm{m}$6-benzyladenine and 0.5 $\mu\textrm{m}$ $\alpha$-naphthaleneacetic acid, petiole explants from 'Cooler Icy Pink' exhibited the greatest frequency of adventitious shoot formation at 40%, which was followed by 'Little Bright Eye'. By comparing with a previous study on assessment of competence for adventitious shoot formation in hypocotyl explant cultures of various cultures, it is indicated that the relative degree of their competence among cultivars varies to the organ used for the source of explant. Excised adventitious shoots were readily rooted on half-strength MS basal medium. Regenerated plantlets were successfully transplanted to potting soil and grown to maturity in a greenhouse.
