Objectives : This study was aimed to define the protective effect of Tissue Cultured Root of Wild Ginseng (CWG) against doxorubicin (Doxo) toxicity, and investigate the anti-tumor synergic effect of CWG in combination with Doxo in tumor-bearing C57BL/6 mice. Methods : Tumor-bearing mice were established by single inoculation with B16/F10 melanoma cells (2$\times$10$^6$/ml) subcutaneously. Tumor-bearing mice (tumor volume between 50-100 mm$^3$) were selected and divided them into control, Doxo, and Doxo+CWG group. Mice of Doxo group were received with Doxo (4 mg/kg of B.W.) intraperitoneally at 0, 4, 8 days after starting the experiment. Mice of Doxo+CWG group were received CWG water extract during 12 days in combination with Doxo treatment. The body weight, tumor volume, tumor weight, and organ weight (heart, liver, kidney, and testis) were measured. And serum SPK, GOT and creatinine values were analysed. Results : The volume and weights of tumor masses in Doxo group were decreased significantly compared with the those of control group. And the those of Doxo+CWG group were not significantly different from the those of Doxo group. Whereas the weight of body, liver, kidney and testis in Doxo+CWG group were increased significantly compared with the those of Doxo group. The level of serum CPK and GOT in Doxo group were increased compared with the those of control group. But the value of Doxo+CWG group were decreased significantly compared with the values of Doxo group. Conclusions : These results suggest that CWG has protective effect against doxorubicin toxicity. And these effect is guessed that is caused in augmentation of vital energy.

Ginseng root explants and calli induced from selected cell lines were cultured on modified Murashige and Skoog's media supplemented with different concentrations of organic or inorganic compounds and plant growth requlators to clarify the effects of chemical composition and plant growth regulators in the medium on the growth of ginseng calli and the production of ginseng saponin. For optimum growth of calli, the concentrations of 2, 4-D and sucrose were the range of 1 to 3 mg/${\ell}$l and 1 to $3\%,$ respectively. And it was clarified that sucrose, nitrogen, phosphate, calcium, magmesian plant growth regulators and their concentrations influcenced the relative biosynthesis of saponin in tissue cultures of Panax ginseng. The patterns of ginsenosides, pharmacologically useful component, were different among the cell lines and contents of ginsenosides were much higher in selected cell lines than in original cell line.

Isolated protoplasts from ginseng (Panax ginseng C. A. Meyer) callus tissue were cultured in modified MS media supplemented with various concentrations of dimethylsulfoxide (DMSO). The cell wall regeneration rate and cell division efficiency of the protoplasts were increased significantly by 1% DMSO treatment. However, there was no difference in the viability of protoplasts between the DMSO treatment and non-treatment. Transmission electron microscopy revealed that the microtubules were oriented in parallel manner to the plasmalemma after 3 days of culture in medium with 1% DMSO. Further, interconnected cellulose microfibrils were observed on the outer surface of the 3-day-cultured protoplasts by scanning electron microscopy These structures shown by electron microscopy were not observed in protoplasts cultured on DMSO-free media. This studies indicates that DMSO supplemented in culture media seemed to stimulate the cell wall regeneration and cell divisions of protoplasts by forming microtubule organizing centers (MTOC).

Mountain ginseng is a perennial crop rarely found in the deep mountains of Korea. The medicinal effect of the mountain ginseng is well known as a panacea in traditional Chinese medicine for a long time. But scientific studies to elucidate the medicinal effect of the mountain ginseng have never been made on account of lack of sample. Recently an improved method of adventitious root culture system through the use of bioreactor has been developed in Panax ginseng that seems to be a reliable way of commercialization of root derived secondary metabolites. This experiment was conducted to evaluated chemotherapeutic effect against human cervical cancer cells by cisplatin (CDDP) and extract of tissue cultured mountain ginseng (ETCMG). CDDP and ETCMG-induced apoptotic cell death in human cervical cancer cell line, HeLa was confirmed by the analysis of cell growth, morphological changes, DNA fragmentation, flow cytometry showed that ETCMG is an inducer of apoptosis and synergizes with CDDP. These results suggest that ETCMG present evidence of anticancer effect and could have a possibly natural therapeutic potential in cervical cancer patients.

A comparative investigation of fine structure of callus cells derived from tissue culture of Panax ginseng was made by electron microscope. Callus was consisted of large superficial cells and small inner zone cells derived from shoot apex tissue cultured for 16 weeks. Large superficial cells were contained the clusters of starch grains surrounded by a double plastid membrane. Especially, electron dense particles were deposited just inside and outside of plastid membrane and also deposited on mitochondria-like and endoplasmic reticulum-like structures. Crystalline body was also found in superficial cells. Small inner zone cells were characterized by presence of proplastids sheathed by short endoplasmic reticulum profiles. presence of spiral configuration of ribosomes and absence of crystalline body. Organ primordia was consisted of a dense cytoplasm and notable nucleate cells derived from nodal tissue cultured for 67 weeks. Proplastids containing starch grains and crystalline bodies were frequently observed; starch grains are of small quantity and does not form the clusters as in inner zone cells; hexagonal crystalline body itself does not have always limiting membrane. Remarkably. in a few cells of primordia, particles resembling the presumptive virus were observed mainly in condensed nuclear chromatin and also in cytoplasm, in mitochondrion-like organelle.

The therapeutic effect of tissue cultured root of mountain ginseng (Panax ginseng) (tcMG) on 2,3,7,8-tetrachlorodaibenzo-p-dioxin (TCDD) induced toxicity in rat was investigated. The rats were assigned into three groups (10 rats/group), control, TCDD exposed group and tcMG treated group after TCDD exposed. $50\;{\mu}g/kg$ of TCDD was injected by i.p. for TCDD exposed group and 30 mg/kg of tcMG saponin was administered for 4 weeks by oral gavage for tcMG treated group. The weights of body, spleen, kidney, thymus, testes and epididymides were decreased in the single TCDD treatment. However these organs was significantly recovered by tcMG saponin except thymus (p<0.05). tcMG decreased the level of hepatic demage maker enzymes, AST and ALP. It also lowered total cholesterol and triglyceride. The level of serum triglyceride was significantly decreased in tcMG saponin treated group compared with the control. Histopathological examination revealed morphological change in the liver spleen, thymus and testes of TCDD treated rats. However they were relatively well preserved in the tcMG treatment group. In conclusion, TCDD induced toxicity was some repaired by tcMG. tcMG may be useful for prevention and treatment of TCDD induced toxicity.

Calli and leaflets of ginseng (Panax ginseng C.A. Meyer) were cultured on 1/2MS media supplement. with kinetin, 2 iP, NAA, 2,4-D and IBA to assess their capacity to regenerate embryoids and organs. Root calli produced numerous embryoids and shoots in 1/2MS medium supplemented with 2 mg/l NAA and 2mg/s 2iP, and the combination of 2 iP and NAA was more effective than the combination of kinetin and NAA in induction of embryoid and shoot from root calli. Culture of leaflet in the medium supplemented with IBA resulted in profuse root regeneration.

Solvent fractions were prepared from traditional herbal drugs which of methanol extracts inhibited $CCl_4$-induced cytotoxicity in primary cultured rat hepatocytes and c ontinuously assayed their effects. Ethylacetate and n-buthanol fractions from Cibotii Rhizoma and chloroform fraction from Gelatina Nigra inhibited the release of LDH and GPT from $CCl_4$-treated hepatocytes, respectively. Water fraction (WAR) among solvent fractions from Astragali Radix showed the most potent inhibitory effect on the release of GOT or GPT by treatment with $CCl_4$. All of solvent fractions prepared from Eucommiae Cortex had no effect on $CCl_4$-induced cytotoxicity. Chloroform and ethylacetate fractions from Rehmanniae Radix Preparata increased the release of GPT from $CCl_4$-treated hepatocytes. n-Hexan, chloroform or ethylacetate fraction from 5 herbal drugs increased the release of LDH, GOT or GPT from normal hepatocytes at the dose of 1.Omg/ml. Administration of WAR suppressed the elevation of GOT, ALP activities and MDA contents in the serum as well as in the liver tissue of $CCl_4$-intoxicated rats. Based on these results, isolation of antihepatotoxic substances from WAR is under the process.

Cotyledon of Panax ginseng was cultured in the growth regulator-free Knudson C medium comprising only several kinds of mineral salts and sucrose. Shoot primordium or callus developed profusely from the cotyledonary tissue and finally plantlets were produced directly from the shoot primordium or indirectly through callus. Microscopic examination revealed that the epidermal cell as well as the mesophyll cell of the cotyledon became meristematic and divided, changing into multinucleate cell or multicellular body, eventually developing into either a shoot primordium or callus.

Tissue culture of the roots of Panax ginseng was carried out to enhance the production of ginseng callus as well as to increase its contents of ginsenosides. A long cylinder type callus mass was formed when cultured IK callus by rotary shaking culture method, the growth ratio of the callus being 7.71 which was approximately 4 fold higher than those obtained by other culture methods. Ginsenosides $Rg_1$, Re and $Rb_1$ could be detected from the callus mass by TLC, however, their total contents were revealed to be approximately 9% compared to that of the fresh ginseng root equivalent by HPLC analysis,.
