The Chinese crude drug, 'Man Sam(蔓蔘)', which is derived from the root of Codonopsis plants of the family Campanulaceae, has been used as a tonic. In China, the same crude drug derived from Codonopsis plants, called 'Dang Same(?蔘)', has been used as remedies for anorexia, fatigue, cough, etc. Although Codonopsis roots have been widely used for medicinal purposes in Korea, the botanical origin of the crude drug has never been studied pharmcognostically. To clarify the botanical origin of 'Man Sam', the root morphology and anatomy were examined for the Korean species of Codonopsis species, such as C. lanceolata (Sieb. et Zucc.) Trautv., C. pilosula (Franch.) Nannf. and C. ussuriensis (Rupr. et Maxim.) Hemsl. The study shows that 'Man Sam' is the root of Codonopsis pilosula.

Nozzle ring is an important part of turbocharger which is applied to today's most diesel engines. Turbo charger nozzle ring is difficult to process and takes a high cost and a long time relatively. For this reason, it is largely produced by using a precision casting. Investment method, the representative technology of precision casting, has excellent dimensional accuracy and can produce complex shapes relatively easily. However, it is difficult to avoid the casting defects such as shrinkage cavity and short shot. This study is to predict the casting defects which could be occurred during the investment method by use of finite element analysis software and to design the process and mold of the marine turbocharger nozzle ring.

In humans, an immediate allergic response to an allergen snay appear as either bronchial asthma unaccompanied by anaphylaxis or a severe bronchial constriction and spasm accompanied by anaphylaxis. Much experimental evidence with isolated asthmatic tissues has shown that histamine is released during the allergic reaction. Paradoxically, antihistamine treatment is ineffective in reversing bronchial asthma or anapllylaxis in a man. The present study objective is to search for protective agents(In-Sam-Yun-Pai-San-Ga-Gam-Bang) against bronchial constriction in treating a anaphylaxis. The result from this study is as follows. A single dose of In-Sam-Yun-Pai-San-Ga-Gam-Bang extract(3ml/kg body weight) 2 hrs prior to histamine-induced bronchial constriction test demonstrated significant protection. Based on the above result, It is considered that In-Sam-Yun-Pai-San-Ga-Gam-Bang can be used in bronchial asthma.
