Coleus forskohlii Briq, of the family Lamiaceae yields a valuable secondary metabolity known as forskolin which is a labdane diterpenoid.. Coleus forskohlii is the only known source of this compound. Forskolin is used in medicine for the treatment of glaucoma, congestive cardiomyopathy and asthma. Morphogenic callus was induced from young leaves on MS medium augmented with NAA and BA. These calli, when subcultured on MS with KN alone gave rise to shoots. The regenerated shoot developed good root system on MS medium fortified with NAA. The fully grown plantlets were transferred to soil for acclimatization. Coleus plant is mainly infected by a fungi Lasiodiplodia theobromae which causes root rot disease. The fungal culture filterate (ECE) of Lasiodiplodia theobromae, has been used in regeneration media to find the MIC and further to select resistant plants to the pathogen. In the present study 40% ECF in the medium showed maximum inhibition and is there fore considered as the MIC level of Coleus forshohlii. This data could prove to be useful for the future for selecting a resistant C.forskohlii plant against the root disease caused by L. theobromae.

Narcotic drugs generally refer to serious and habitual hidden rash such as opium, heroin, methyphetamin, nabinol, cocaine, and so forth. At present, narcotic drugs are spread unchecked and are causing a big social problem. So many countries and narcotists are making every effort to set up a barricade against narcotic drugs. And there is a limit suitable treatment for them. Thus Tuo Yin Tang Jiang is developed. As indicated by Chinese letters, Tuo Yin Tang Jiang(TYTJ) is a crude drug. It is a traditional chinese medicine developed by the study done from June in 1998 to June in 1999 that Hubeisheng was entrusted with by People's Republic of China. This study is a treatise on etiology and syntomatology of narcotism. TYTJ is a medicine which is in accord with Pharmacopeia of the People's Republic of Chinal) in order to remove from the body the toxic materials resulting from narcotic drugs such as opium and heroin. According to the standard diagnosis on narcotism, 105 cases are studied and treated at the Rehabilitation Center attached to Enshi Autonomous Region Hospital in Hubeisheng. 105 cases are divided into 2 groups by double-blind method. One is the experimental group which has 56 cases. The other is the control group which has 49 ones.13 cases among 105 cases are addicted by intravenously injections. 9 cases are by oral takings. It took 10 days for this experiment to be performed. Two groups didn't show a striking individual variation based on the age, gender, period of taking drugs, withdrawal symptoms, complication, and state of health. The experimental group had a higher effect of treatment than the control group had. TYTJ treats diseases effectively and has no side effect, irrespective of the serious or slight addiction to opium and morphine.

Many plant species are used in China in tradtional medicine for the prevention and treatment of cancer. This paper presents some of these species with defals on other pharmacologic evaluation and its tradional Chinese meditional uses. The known bioaktivities and some chemical constituents of each of the species given. Information on bioactivities of each species resulting from tests on experimental animals are given. Many of the known chemical constituents of each species are given. Various species of plants elective for various types. In this meeting I will present on some antitumor of the plants which are as follows ; (1) Akebia trifoliata(Thunb.)Koidz. ((2) Panax notoginseng (Burk.) F, H, Chen ., (3)Ziziphus jujuba Mill., (4)coriotus versicolor(Fr.) Quel., (5) Trich osanthes kirilowii Maxim., (6) Ficus carica Linnaeus., (7) Acanthopanax senticosus(Rupr. et Maxim.)Harms.,(5) Hibiscus mutabilis Linnaeus.,(9) Arctium lappa Linnaeus., (11) Agrimonia pilose Ledebour and (12) Hedyotis diffusa Willd.

seeding rates(1.5,2.0,3.0 and 3.5l/10a). There were no differences in the yield components such as length of stem and ear diameter of stem number of branch, internode and ear, and yield of fresh and dry stem between the seeding methods with drilling and broadcasting, but yield components such as length of stem and ear, diameter of stem, number of branch, internode and ear, and yield of fresh and dry stem increased with seeding rates of from 2.5l /10a to 3.5l/10a. Therefore potimum rates and methods of sowing were from 2.5l/10a to 3.5l/10a with seeding at the drilling and broadcasting.

This study was carried out to determine the effect of sowing time on the flowering, growth and yield of Schizonepeta tenuifolia Briquet. Emergence and flowering dates in the sowing time from March 30 to April 30 were earlier than those of the other sowing times. In the sowing time from March 30 to April 30, length and diameter of main stem, number of node per main stem, number of branch per plant and fresh, and dry weight of stem were greater than those of the other sowing times. Yield components such as ear length, main stem length and diameter, branches per plant, number of node and ears per plant, yield of stem in fresh and dry were the highest at the sowing time from March 30 to April 30. Optimum sowing time of Schizonepeta tenuifolia Briquet were shown to be from March 30 to April 30 in southern areas of Korea.

To develop optimumal storage method of root of Bupleurum falcatum Radix grown on major cultural herbal medicine materials, root of Bupleurum falcatum Radix was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. Conclusionally, vacuum packing and complete sealing with polyethylene film appears to be optimal for storage of Bupleurum falcatum Radix.

Many ascomycetes were collected at Mt. Moak, Mt.Jiri, Wanju and Mt.Manduckfrom September 1995 to September 1997. They were identified . According to the reusulting, Caloscypha fulgens, Geoglossum peckianum, Dasyschyphus sulfurous, Cudoniella acicularis and Biatorella resinae are newly to Korea. They weredesigned Korean common names by author.
