This study was carried out to analyse saikosaponin contents in adventitious root formed from callus of Bupleurum falcatum L. The induction of adventitious root from callus of 4 weeks of culture was most favorable to MS medium supplemented with 0.1 mg/L 2,4-D. The adventitious root formation ratio per callus was highest when the size of callus was 900 to 1,000 $\mu$M The content of saikosaponin a and d was 2089$\pm$124 $\mu$g and 4778 $\pm$ 214 $\mu$g at 150 days of culture respectively on the basis of g dry root wt, whereas that of saikosaponin c was 3492 $\pm$ 123 $\mu$g at 60 days of culture.

This study aimed to investigate the effects of Chaihushugansan and Chaihuyigantang on the change of monoamine-contents in the hypothalamus of mice induced by the immobilization stress. Each formula(1.0g/kg) was injected intragastrically to mice 1 hour prior to the immobilzation stress(15 minutes) before measuring the change of monoamine-contents level in mice hypothalamus. The results were as follows: 1. DA content at control group showed significant change. CHSGS group and CHYGT group showed significant decrease.(P<0.05) 2. NE content of the control group was increased than normal group. NE content of the CHYGT group was shown a significant decrease than control group.(P<0.05) 3. DOPAC contents didn't show significant changes at any groups. 4. 5-HT contents didn't show significant changes at any groups. 5. 5-HIAA contents at CHSGS group and CHYGT group showed signifiant changes.(P<0.05, 0.01) These data revealed that chaihushugansan and chaihuyigantang might have the anti-stress effect through the control of DA and NE contents in the hypothalamus.

Mycoplasma-like organisms (MLO) were identified from three plants. The disease symptoms show stunting, yellowing and witche's broom on Cnidium officinale Makino collected from Ulreung Island, Bupleurum falcatum L. collected from Jangsu, and Plantago asiatica L. collected from Daegwanreung. The particles of MLO were observed in the phloem tissues by a Hitachi Hu-11E electron microscope. C. officinale infected with MLO was frequently observed in Ulreung Island.
