When the leaf and stem tissues of Rehmannia glutinosa were cultured on MS medium with plant growth regulators, shoots were regenerated on MS medium with TDZ(0.01 to $2.0{\mu}M$), and root initiation was better on MS medium treated with NAA(0.01 to 2.0mg/$\iota$). On $B_5$ medium, shoot regeneration was better on medium with TDZ than those with Quincrac, NAA, and 2.4-D. The addition of Quincrac, NAA, and 2.4-D inhibited shoot regeneration on MS medium, but promoted shoot regeneration on $B_5$ medium. Shoot regeneration and growth was better on MS medium with the combination treatments of 2.4-D 0.01mg/$\iota$ and TDZ 0.01, 0.1 and $2{\mu}M$ compared with other treatments. Also shoot regeneration and growth on B_5 medium showed the similar results to that on MS medium.

Oxidant stress is a well-known pivotal parameter for the degenerative immune diseases including asthma, atopic dermatitis, and rhinitis. In order to screen for anti-asthma agents effectively, we first established the infrastructure of high throughput screening(HTS) for anti-oxidant agents from agricultural products and/or oriental medicine library extracted with water, methanol, dimethyl sulfoxide, ethyl acetate and juice, Using the screening system, we found that Chaenomelis langenariae, Rhus javanica L., Camellia sinensis, Helianthus annuus and Angelica utilis Makino had strong anti-oxidant activity. Moreover, Helianthus annuus, Rehmannia glutinosa Libo and Angelica utilis Makino have protection activities by treatment of an oxidant hydrogen peroxide. Together, these results suggest that screened agents could be potential agents against asthma, although the in vivo studies should be clearly tested.

The effects of four extracts of medicinal herbs, Rubus coreanum, Acorus calamus, Morus alba and Rehmannia glutinosa on hair growth activity and acnes control were investigated. In the course of screening natural extracts for hair growth, we found that the extract of dried root of Rubus coreanum has the hair growth promoting effect. After topical application of these extracts to the back of C57BL/6 mice, the earlier conversion of telogen-to-anagen phase was induced. The growth of dermal papilla cells and mouse vibrissae hair follicle cultured in vitro, however, was not affected by treatment of these extracts. Furthermore these extracts do not possesspotent inhibitory effect on $5{\alpha}-reductase$ I and II activity and anti-bacterial effect on Escherichia coli , Propionibacterium acnes, Pityrosporum ovale, Staphylococcus aureus, Staphylococcus epidemidis, and Candida albicans. RT-PCR analysis showed that these extracts did notinduce mRNA levels of growth factors such as insulin-like growth factor-I, keratinocyte growth factor, hepatocyte growth factor and vascular endothelial growth factor in dermal papilla cells. These results suggest that Rubus coreanum has hair growth promoting effect. However, the effects of these materials on the hair growth promotion are not mediated through inhibition of $5{\alpha}-reductase$ I and II activity, stimulation of hair follicle cells and expression of growth factors in the dermal papilla cells.

This is the first study to establish a complete protocol for micropropagation of Rehmannia glutinosa from root segments. The study involved investigating the effect of plant growth regulators on in vitro shoot regeneration and rooting and identifying substrates supporting survival and growth performance of ex vitro seedlings. A Murashige and Skoog (MS) medium containing 30 g/L sucrose for shoot induction and 0.2 mg/L indole-3-acetic acid (IAA), 1 mg/L 6-benzylaminopurine (BAP), and 1 g/L polyvinylpyrrolidone (PVP) for shoot multiplication resulted in the highest number of shoots per explant and shoot height. Applying a medium containing 0.5 mg/L IAA and 1 g/L PVP yielded optimal rooting of the shoots grown in vitro. Compost enriched with microbial inoculants and perlite enhanced seedling growth better than that with organic biofertilizer-free substrates (soil and sand). We recommend the continuous production of micropropagated R. glutinosa seedlings from root segments under the aforementioned conditions as a possible propagation technique for crops of this species.
