Chinese crude drug 'Se Sin'(細辛)has been used to cure headache, cough and expectorant. To the botanical origin of 'Se Sin', Zhong-yao-zhi(中葯志) reported Asarum heterotropoides var. mandshuricum. A. sieboldii and A. sieboldii var. seoulensis, and Zhong-yao-da-ci-dian(中葯大辭典) reported Asarum heterotropoides var. mandshuricum and A. sieboldii of Aristolochiaceae. In Korea, this crude drug has been used as a Korean folk remedy for tothache and aromatic. The botanical origin of 'Se Sin' is considered to be Asarum species of Aristolochoaceae. But there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'Se Sin', we studied on the anatomical characteristics of Asarum species growing wildly in Korea i.e. A. maculatum, A. sieboldii, A. sieboldii var. seoulensis, and of 'Se Sin' from Korea on Korean market. Through our studies, the botanical origin of 'Se Sin' from Korea was proved to be whole plant of Asarum sieboldii and A. sieboldii var. seoulensis.

To clarify the botanical origins of oriental medicines which have been argued or confused for plant origins, species of original plants were investigated through the textural research for oriental medicines and the comparison of Chinese, Korean, Japanese and North Korean Pharmacopoeia. Twenty oriental medicines were studied; Angelicae Gigantis Radix, Rhei Rhizoma, Atractylodis Rhizoma Alba, Aconiti Lateralis Radix Preparata, Acanthopanacis Cortex, Osterici Radix, Cnidii Rhizoma, Saposhnikovae Radix, Magnoliae Cortex, Paeoniae Radix, Liriopis Tuber, Zanthoxyli Fructus, Achyranthis Radix, Sinomeni Caulis et Rhizoma, Polygonati Rhizoma, Cinnamomi Cortex, Visci Herba et Loranthi Ramulus, Fritillariae Thunbergii Bulbus, Pogostemonis Herba, and Curcumae Longae Radix.

Binary vectors, pBI-ActR1, pBI-ActF1 and pBSH-ActR1, were constructed using pGA642, the replication origin of pTi12 and the rice actin promoter. The sizes of pBI-ActR1, pBI-ActF1 and pBSH-ActR1 were 12.9 kb, 13.2 kb and 11.95 kb, respectively. These vectors containing a rice actin promoter followed by a GUS structural gene could induce stronly the expression of GUS gene in transformed rice cells. Rice explants from 3-4 day old seedlings after germinatin were cocultured with A. tumefaceins harboring pBI-ActR1, pBI-ActF1 or pBSH-ActR1, and then GUS expression in the explants was assayed. Transformation of rice explants by these binary vectors was tissue-specific, such that the meristematic regions of shoot apex, root and hypocotyl were transformed by these binary vectors.

This study compared Korean names of 449 herbaceous landscape plants with Chinese and Japanese names to identify the origin of their Korean names. The results were as follow ; 1. Korean herbaceous plants named after Chinese names were 71 species. They could be classified into 4 typical groups of their origin : plants named from slight or partial changes of Chinese names, plants with a prefix or suffix attached to Chinese names, plants having names translated from Chinese names, and plants with the same names as Chinese. 2. Korean herbaceous plants derived from Japanese names were 378 species. They also could be classified into 4 typical groups of their origin; plants with new names in partial combination of Japaneses and Korean names, plant having names directly translated from Japaneses names, plants with the same names as Japanese, and plants having names erroneously translated from Japaneses names.

Phosphorus has been known as an essential component of animal body. However, the requirement has not been determined precisely because of the variable bioavailabilities of feedstuffs from plant origin. The bioavailability of P in various feedstuffs of plant origin varies from 10 to 60%. Digestibility and availability of the P differed considerably depending on the feed. The lowest values were found for maize (under 20%), the highest for wheat and triticale (over 50%). This is due to the proportion of phytate and the presence of intrinsic phytase. And the digestive tract of monogastric animals does not contain sufficient amounts of phytase, an enzyme that hydrolyses the unavailable phytate complexes to available, inorganic orthophosphates. Microbial phytase supplementation improves the P availability, and both intrinsic plant and microbial phytase improves the availability of P in feedstuffs of plant origin. In a mixture of feeds with low and high activity of intrinsic phytase and/or supplemented by commercial phytase, the P availability is additive. However, in the light of current results it seems that exceeding the P availability equal to 60-70% is unrealizable even at large microbial phytase doses.

Safflower is a world-wide plant for multiple uses. flower of safflower is honghwa(紅花) which has been used for heart disease in oriental medicine. but its seed was not used in oriental medicine. after the publication of "Shinyak(神藥)" - the late 1980s, its seed(紅花子, hongwhassi) was known as good for bone fracture, osteoporosis and menopausal disorders. so many researchers studied hongwhassi and delivered lots of papers. the concern of each paper is different. this paper is a review paper. this paper studied documentary records about hongwhassi, and analyzed hongwhassi research trend. the trend consists of cultivation, ingredient analysis, osteoporosis, atherosclerosis, periodontal ligament and phytoestrogen. many papers lack of information about plant origin. so this paper supplements the standard form of plant origin(when sowing, where grow up, which direction, what kind etc).

This study was carried out to establish in vitro propagation system influenced by plant growth regulators through organogenesis with three different seed sources (China, Mongolia and Russia) for conservation of genetic resources in Northeast Asia. The experiment compared two different carbon sources (commercial sugar, sucrose), which showed no significant differences in germination rate. Induced adventitious buds from leaf segments were found to be highly effective when supplemented with 1.0 mg/L BA, 1.0 mg/L Kinetin, and 5.0 mg/L IAA, in the case of Chinese origin 96.8%, Russian origin R-1: 95.6%, R-2: 85.6%, and Mongolian origin M-2: 77.8%. It was effective in BA and Kinetin with supplemented with IAA, respectively. Shooting development was also efficient in Woody Plant Media (WPM) supplemented with 1.0 mg/L BA, 1.0 mg/L Kinetin and 5.0 mg/L IAA.

A well-defined relative degree, which is one of the basic assumptions in adaptive control or nonlinear synthesis problems, is addressed. It is shown that this is essentially a necessary condition for asymptotic tracking in discrete-time nonlinear systems. To show this, tracking problems are defined, and a local linear input-output behavior of a discrete-time system is introduced in relation to a well-defined relative degree. It is then shown that if a plant is invertible and accessible from the origin and a compensator solves the local asymptotic tracking problem, then the plant necessarily has a well-defined relative degree at the origin.

Korean folk medicine "Ggaenggaengipul" has beenused to dlear heat and treat chronic childfood mutitional impairment, diarrhea, jaundice, haemorrhoid, inflammation, anepithymia, nausea and egestion .The crude drug often used as a supstitute for the more expensive "Huang Lian " (황연) in Korea and China. With regard to the botainicla origic of " Ggaenggaenigipul" , it has never been studied pharmacognostically. To clarify botanical origin of " Ggaenggaegipul" , the morphological and anatomicla characteristics of the leaves, petiole, rhizoma, and radix of Jeffersonia dubia BENTH were studied.
