The anticancer activities of the extracts from Acanthopanax senticosus Harms, Ephedra sinica Stapf, Rubus coreanus Miq and Artemisia capillaris Thunb were compared according to extract systems. About 70% of the growth of human hepatocarcinoma cancer cell was inhibited in adding 1.0 mg/ml of the water extract from Rubus coreanus Miq with ultrasonification at
. The growth of human normal lung cell was limited to 25% in adding the extracts with ultrasonification at
. The effect of extracts obtained by only water and with ultrasonification on different of human promyelocytic leukemia cells was also observed.

This Study was carried out to select bed soil and growth regulator which are effective for the macro propagation by cutting of Cudrania tricuspidata Bureau. The rooting of Cudraniae tricuspidata showed good result when the bed soil was coarse soil, rooted hardwood cutting 56.9%, and softwood cutting 62.3%. The rooting of Cudraniae tricuspidata showed good result when treated by growth regulator IBA 100 ppm, rooted hardwood cutting 57.9%, and softwood cutting 89.2%.

Reactive oxygen species (ROS) are continuously produced at a high rate as a by-product of aerobic metabolism. Several lines of evidence provided that ROS appears to cause to develop aging and various diseases. High level of hyaluronic acid with decreased molecular weight has been detected in patients with inflammatory diseases including rheumatoid arthritis. In this study, we have conducted to investigate the antioxidant and hyaluronidase inhibitory activities of Prunus persica Batsch var. davidiana Maximowicz in order to screen the bioactive substances which can be developed as possible anti-inflammatory agents. Among the extracts of Prunus persica Batsch var. davidiana Maximowicz, EtOAc extract exhibited the strongest effect on antioxidant experiment such as DPPH, Ferric- Thiocyanate and Rancimat. Also, EtOAc extract showed a potent hyaluronidase inhibitory activity.

Korean Journal of Medicinal Crop Science, volume 12, issue 4, 2004, Pages 295~299
This study was carried out to examine seed characteristics of Artemisia capillaris and the effects of different temperature and light on its seed germination, and of sowing date on its growth and yield. A seed of A. capillaris, 0.79 mm in length diameter, 0.39 mm in width diameter and 0.054 g in thousand-kernel weight, was extremely small, vertical pinstripes in the surface of seed, and long oval of dark brown in shape, and its maturity occurred September to October. A germination rate was superior at light conditions and 20 to
in temperature. Although its germination became shorter as the higher temperature. Its emergence rate was the highest in sowing at March 30. But the growth and yield potential was the best when sowed at March 20. The earlier the sowing date, the higher yield.

Korean Journal of Medicinal Crop Science, volume 12, issue 4, 2004, Pages 300~303
This experiment was conducted to study the effect of growth characteristics and yield by different planting density on Wasabia japonica Matsum. in water culture. Plant height, leaf length, petiole length was long in spacious planting
and short in dense planting
. Rhizome width was thick in spacious planting, and was thin in dense planting. Rhizome weight per plant decreased by increasing planting density, but rhizome yield was increased by high planting density. But distribution of rhizome weight did not show significant difference at different planting density.

Immune enhancing activities of water and ethanol extracts of Hypericum perforatum L. (HP) were examined. HP extracts inhibited the growth of human hepatocarcinoma, human gastric cancer cell and human breast cancer cells in concentration-dependent mammers over a concentration range of
, showing inhibiton of more than 80% with the concentration of 1.0 mg/ml. However, HP the same concentration. Overall selectivity of the extracts on the three human cancer lines was over 3.5, which is higher than those from the conventional herbs. The growth of human immune B and T cells was enhanced up to 1.4 to 2.0 folds by the addition of the extracts for 4 days, compared to controls. Ethanol extracts of HP after 6 days incubation increased the secretions of tumor necrosis factor-alpha
from T cells and interleukin-6 (IL-6) from B cells to 6.7 pg/cell and 6.8 pg/cell, respectively. These results suggest that HP has a potent immune enhancing effect.

The cytotoxic effects of water and ethanol extracts of Echinacea purpurea (L.) (EP) and chloroform, ethyl acetate, butanol and aqueous fractions from each extract of EP were examined. Every extract and fraction of EP inhibited the growth of human hepatocarcinoma, human gastric cancer cell, human breast cancer cells and human lung carcunoma in concentration-dependent manners over a concentration range of
. Most extracts and fractions with the concentraction of 1 mg/ml showed strong inhibition of more than 70% for every cancer cell. Only aqueous fractions of each extract showed very weak inhibitons of 12 to 25% on the growth of human normal lung cell with the concentration of 1 mg/ml. Overall selectivity of the extrats and fractions on the four human cancer cell lines was over 2.5. These results indicate that EP has a very potent selective toxicity for cancer cells.

The purpose of this research was to investigate the effect of Orostachys japonicus A. Berger (OJB) on the immune system. Administration of OJB (500 mg/kg) enhanced viability of splenocytes and thymocytes in BALB/c mice, and also OJB increased of splenic T lymphocytes, significantly, increased CD4 positive
cells and CD8 positive Tc cells. OJB markedly, enhanced the production of
in mice serum. OJB accelerated the apoptosis of L1210 and U937 leukemia cells and increased the expression of apoptosis-related ICE, c-myc, p53 gene. These results suggest that OJB have an immuno-regulatory and anti-cancer activity.

Cortex of Ulmus davidiana var. japonica N. and Hemipteleae davidii P. have been used without classification according to countries as oriental medicine for treatment of various disorders. This study was conducted to elucidate the difference in antioxidant activity and total phenol content of these medicinal materials. Root cortex and trunk cortex of two medicinal plants were extracted with 80% ethanol
and water (at room temperature), respectively. All of the extracts at
, showed more effective scavenging activity on superoxide radical than ascorbic acid, and 80% ethanol and water extracts of Ulmus root cortex (URC) was more effective. Scavenging activities on DPPH radical of 80% ethanol extracts from URC and Ulmus trunk cortex (UTC) at 10
, (41.4, 35.6%) were higher than those of the other six extracts and
. Inhibitory activities on human low density lipoprotein (LDL) oxidation of 80% ethanol extracts from UTC and URC (84.3, 81.7%) at
were higher than those of the other six extracts and
. However, antioxidant activities on linoleic acid peroxidation of all of the extracts were relatively lower than that
. Total phenol content of 80% ethanol extract from URC was the highest value as 50.8% and that of water extract from HRC was the lowest as 5.6% among the extracts. From these results, it is suggested that Ulmus root cortex was the most effective in antioxidant activity.

Presowing seed treatments used to enhance the rates of germination and afterward seedling emergence have not occasionally shown the same rate in indoor and field. The treatments considering germination mechanism and factors affecting germination must be totally included in indoor experiments so that the results drawn can be reproduced in the field. Seed germination is controlled by Phytochrome-mediated action changed with composition rates of red and far-red lights. Sunlight can penetrate soil into
depth, which in turn means that seeds having
in their width may receive the light if soil was covered 3 times over them. The penetrating light, moreover, turns to more far-red light than red light reverse to the sunlight. For germination tests after the artificial presowing seed treatments, therefore, seeds of smaller than 2 mm (< 2 mm),
, and larger than 3 mm (> 3 mm) must be done with incandescent lamp (IL) having more far-red light, with IL or in darkness, and in darkness, respectively. The 96 papers published in 13 Korean scientific journals up to the end of 2003 were analysed on the basis of the above explanation. 91 species were used 147 times as experimental materials; 101 times for < 2 mm seeds, 24 times for
seeds and 22 times for > 3 mm seeds. If they were analysed as the light sources used for germination tests, correct applications reached more and less than 60% in both
and > 3 mm seeds but 23% in < 2 mm seeds, conclusionally meaning that when the experimental results in the scientific papers were applied into farming practices, care was taken of their application because most of medicinal plant seeds were very small.
