Several biological activities of extracts from roots of Cichorium intybus Linne (Compositae) were studied in this paper. The antiinflammatory activity of the methanol extract of this root was investigated against carrageenin induced edema in rat‘s hind paw. Significant inhibitory effects were observed at the dose of 1,000 mg/kg and were compared with aspirin as a control. The hepatoprotective activities of the methanol extract, ethylacetate and butanol fraction were studied on mice whose livers are damaged by $CCl_4$. The serum transaminase activities (ALT, AST) were reduced at the dose of 1,000 mg/kg of the methanol extract, 500 mg/kg of ethylacetate and butanol fraction, respectively. The bile juice secretion was also increased significantly from each fraction. The antidiabetic activity was examined on strepto-zotocin-induced diabetic rats with methanol extract. Methanol extract gave a significant reduction of blood glucose levels in 1 week and 3 weeks.

사염화탄소(carbon tetrachloride, 이하 $CCl_4$라함)에 의한 간 중독시 flavonoids가 미치는 영향을 보기 위하여 $CCl_4$를 투여한 뒤 rutin, hesperidin을 주사하여 경시적으로 간 microsome과 혈청중 total cholesterol, transaminase(GOT, GPT) 및 alkaline phosphatase(Alk. P) 활성도를 측정 비교하여 다음과 같은 결론을 얻었다. (1) 간장중 total cholesterol 함량은 rutin과 hesperidin 1회 투여후 1일에 대조군과 비교할 때 감소하다가 2일에 45%까지 증가되었으나 4일 후에는 정상으로 완전히 회복 되었다. 이와 같은 현상은 혈청중 cholesterol 함량에도 직접적으로 영향을 주어 시간이 경과함에 따라 어느정도 저하됨을 알 수 있었지만 혈청중에서 positive한 결과를 얻기는 어려웠다. (2) 간의 microsome 분획의 Alk. P 활성도는 대조군의 활성치에 비하여 2일에 급격히 증가를 보인 후 4일만에 대조군보다 낮은 활성을 보이다가 6일까지 완만하게 증가하였다. 그러나 본 연구에서 Alk. P 활성도는 $CCl_4$ 투여군과 비교할 때 flavonoids 투여후 별다른 변동은 없었다. 그러나 혈청중 Alk. P 활성도는 hesperidin 투여로 인하여 저하 효과를 나타냈다. (3) GPT 활성도를 측정한 결과 간의 microsome 분획에서는 hesperidin 2회 투여에서, 그리고 혈청중 GPT 활성은 rutin과 hesperidin 두군 모두에서 아주 낮은 활성을 보여 flavonoids가 $CCl_4$ 투여로 인한 간독성을 해독하는 작용이 있음을 보여 주었다. (4) $CCl_4$독성을 일으킨 흰쥐의 간 microsome내 GOT 활성은 rutin 투여로 인하여 불규칙한 변동을 보여 rutin이 GOT활성에 별다른 영향을 미치지 않는 것으로 나타났다. 또한 hesperidin 투여군에서는 증감의 변동없이 대조군치와 거의 비슷한 수준을 유지하였지만 $CCl_4$ 투여군과 비교할 때 낮은 활성을 보였다. 혈청중에서 GOT 활성은 flavonoids 1회 투여군에서는 4일만에, 2회 투여군에서는 6일만에 서서히 영향을 미침을 알 수 있었다. 이상과 같이 $CCl_4$에 의하여 상승되는 total cholesterol, GPT, GOT, Alk. P의 활성도는 flavonoids중 rutin과 hesperidin 성분이 감소시키는 작용이 있는 것으로 보이며, 특히 hesperidin 성분은 $CCl_4$ 중독을 억제 또는 방어하고 치료에 효과가 있는 것으로 본다.

Glycyrrhizae Radix aqua-acupuncture solution (GRAS) and Glycyrrhizae Radix water-extracted solution (GRWS) were prepared and tested for organ toxicities, antitumor activities, and immunomodulatory effects. The organ-toxicity of GRAS to male ICR mice was studied by the measurements of glutamic oxaloacetic transaminase (GOT), glutamic pyruvate transaminase (GPT), lactate dehydrogenase (LDH), and alkaline phosphatase (ALP-s) activities after injection of GRAS for 7 days. The activities of GOT, GPT, LDH, ALP-s were decreased with GRAS. It was shown to possess considerable toxicity toward various tumor cell lines. Concentration of GRAS at 1.5g/ml and 3g/ml resulted in more than 80% inhibition of growth in Ehrlich ascites tumor cells (EATC), Hepa1c1c7, and HeLa cells. Toxicity of GRAS to A549 revealed that 68% inhibition of growth. GRWS at the concentration of 3g/ml showed more than 80% inhibition of growth with EATC, Hepalclc7, A549 and HeLa. In morphological study, the number of cells were decreased, and the shape of cells was round-form in EATC, Hepalclc7, A549 and HeLa cells with GRAS. Administration of GRAS inhibited the growth of EATC in vivo. Mice given EATC at 1.5g/ml or 0.3g/ml GRAS had 16.7% to 50% survival after 21 days. GRAS increased the proliferation of T and B cells and the cytolytic activity of purified T cell. The biosyntheses of nucleic acid and protein of EATC, Hepalclc7, A549 and HeLa cells were inhibited by GRAS.

The antioxidant activities of fermented red ginseng (FRG) were investigated in vitro and in vivo. The contents of total polyphenol and total flavonoid in FRG extracts were $17.01{\pm}2.00$ ${\mu}g/mg$ and $18.42{\pm}3.97$ ${\mu}g/mg$, respectively. These extracts were capable of directly scavenging ${\alpha}$, ${\alpha}$-diphenyl-picrylhydrazyl free radicals. The antioxidative effects of the FRG extracts in streptozotocin (STZ)-induced diabetic rats were also investigated. The activities of plasma alanine transaminase, aspartate transaminase, and ${\gamma}$-glutamyltransferase were significantly decreased by extract administration as compared to an STZ control group. Hepatic glutathione content depleted by STZ treatment was significantly increased by treatment of the FRG extracts, but the elevation of lipid peroxide content induced by STZ was significantly decreased by the extracts. Activities of superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase decreased after STZ-treatment were recovered by the treatment of the FRG extracts. These results indicate that FRG extracts have antioxidative effets in STZ-induced diabetic rats.

The acute toxicity of fthalide in rat was studied in vivo by the observations of the changes in hematogram, serological parameters, content of cytochrome p-450, activities of NADPH-cytochrom c reductase, glucose-6-phosphatase, and the contents of cholinesterase and carboxylesterase in liver. Fthabde is a practically non-toxic substance(LD50 is 3.86g/kg), but rats were intoxicated with fthabde at a oral dose of 100 mg/kg for 12 days. WBC were significantly decreased and activities of ALT and LDH, on the cotrary, the content of glucose in serum were slightly increased. Cytochrome p-450 and lipid peroxide in liver were significantly increased in the fthalide-intoxicated rats. The longer administration of fthalide showed further increase of carboxylesterase activity in liver and serum, but decrease of activities of glucose-6-phosphatase and cholinesterase in liver and serum. These results show that fthatide can induce the hepatocellular injury and neurotoxicity.
