Taklysodoksan(TSS) was a drug used in the treatment of carbuncle and cellulitis in oriental medicine. The purpose of this Study is to investigate the anti-cancer effect of TSS, the proliferation of immunocytes and nitric oxide(NO) production from peritoneal macrophages of mice. This Study estimated the proliferation of Ll210 cell lines, mouse thymocytes and splenocytes and NO production from peritoneal macrophages in vitro and vivo. The proliferation of cells was tested using a colorimetric tetrazoliun assay(MTT assay). From the in vitro and vivo Study of TSS treatment, it did not effect the proliferation of L1210 cells. It also did not have any positive prodution of NO in peritoneal macrophages. This results suggest that TSS treatment in WanBingHuiChun(萬病回春) did not have significant anti-cancer effect and immuno-action comparing with TSS treatment of WaiKeZhengZhong(外科正宗).

According to the Leukemia and Lymphoma Society, leukemia is a malignant disease (cancer) that originates in a cell in the marrow. It is characterized by the uncontrolled growth of developing marrow cells. There are two major classifications of leukemia: myelogenous or lymphocytic, which can each be acute or chronic. The terms myelogenous or lymphocytic denote the cell type involved. Thus, four major types of leukemia are: acute or chronic myelogenous leukemia and acute or chronic lymphocytic leukemia. Leukemia, lymphoma and myeloma are considered to be related cancers because they involve the uncontrolled growth of cells with similar functions and origins. The diseases result from an acquired (not inherited) genetic injury to the DNA of a single cell, which becomes abnormal (malignant) and multiplies continuously. In the United States, about 2,000 children and 27,000 adults are diagnosed each year with leukemia. Treatment for cancer may include one or more of the following: chemotherapy, radiation therapy, biological therapy, surgery and bone marrow transplantation. The most effective treatment for leukemia is chemotherapy, which may involve one or a combination of anticancer drugs that destroy cancer cells. Specific types of leukemia are sometimes treated with radiation therapy or biological therapy. Common side effects of most chemotherapy drugs include hair loss, nausea and vomiting, decreased blood counts and infections. Each type of leukemia is sensitive to different combinations of chemotherapy. Medications and length of treatment vary from person to person. Treatment time is usually from one to two years. During this time, your care is managed on an outpatient basis at M. D. Anderson Cancer Center or through your local doctor. Once your protocol is determined, you will receive more specific information about the drug(s) that Will be used to treat your leukemia. There are many factors that will determine the course of treatment, including age, general health, the specific type of leukemia, and also whether there has been previous treatment. there is considerable interest among basic and clinical researchers in novel drugs with activity against leukemia. the vast history of experience of traditional oriental medicine with medicinal plants may facilitate the identification of novel anti leukemic compounds. In the present investigation, we studied 31 kinds of anti leukemic medicinal plants, which its pharmacological action was already reported through many experimental articles and oriental medical book: 『pharmacological action and application of anticancer traditional chinese medicine』 In summary: Used leukemia cellline are HL60, HL-60, Jurkat, Molt-4 of human, and P388, L-1210, L615, L-210, EL-4 of mouse. 31 kinds of anti leukemic medicinal plants are Panax ginseng C.A Mey; Polygonum cuspidatum Sieb. et Zucc; Daphne genkwa Sieb. et Zucc; Aloe ferox Mill; Phorboc diester; Tripterygium wilfordii Hook .f.; Lycoris radiata (L Her)Herb; Atractylodes macrocephala Koidz; Lilium brownii F.E.

We investigated effect of small black soybean fraction (SBSF) T cell-mediated responses for tumor surveillance and proliferation in leukemia cells in vitro. Each SBSF butanol fraction (SBSFBu) and SBSF chloroform fraction (SBSFCh) was administered p.o. once a day far 21 days in BALB/c mice and then levels of serum cytokines and subpopulation of lymphocytes were measured. Moreover, SBSF fraction was treated into the cultured various cell lines for proliferation in leukemia cell lines, NO production by RAW264.7 cells, and expression of p53 gene in U937 leukemia cells. These results showed that SBSFBu increased levels of serum IL-4but not IL-2 and IFN-${\gamma}$, and increased expression of CD4$^+$ T cells and CD8$^+$ T cells in splenocytes in vivo, while SBSFCh increased levels of serum IL-2 and IFN-${\gamma}$ but decreased IL-4, and increased CD8$^+$ T cells but not CD4$^+$ T cells. Moreover, both of SBSFBu and SBSFCh inhibited proliferation of HL60, U937, and L1210 leukemia cell lines in a dose-dependent manner, up-regulated NO production by RAW264.7 cells in a dose-dependent manner, and enhanced expression of p53 gene in U937 leukemia cells. Our findings indicate that SBSFBu and SBSFCh may enhance T cell-dependent immune responses, and that both of SBSFBu and SBSFCh may inhibit proliferation of leukemia cells by up-regulation of NO production and expression of p53 gene.

The purpose of this research was to investigate the immunoregulatory effect and the leukemia cell apoptosis of EtOH extract of OGAPI(OGP). The proliferation of cultured splenocytes, thymocytes and mesenteric lymph node cells were enhanced by the addition of OGP. Splenic and thymic T lymphocytes, especially TH and Tc cells were significantly increased in OGP-administered mice. OGP markedly increased the production of γ-interferon in mice serum and accelerated the phagocytic activity in peritoneal macrophages. OGP treatment enhanced the apoptosis of L1210 mouse leukemia and Jurkat, Molt4 human leukemia cells, and increased the expression of apoptosis-related ICE, c-myc, p53 gene in Jurkat cell. These results suggest that OGP have an immunoregulatory action and anti-cancer activity.

Antitumor and anti-metastatic effects of mineral powder(MP) were studied. In the present study, MP did not exhibit the any cytotoxic activity against leukemic cells such as L1210 and U937 tumor cell lines in vitro. Also, MP did not exhibit the any cytotoxic activity against solid cells such as A549 and B16-BL6 tumor cell lines in vitro. However, in vivo, MP exhibit a significant antitumor activity in BDF1 mice bearing Lewis lung carcinoma cells(LLC) with inhibition rates of 46 and $23\%$ at 200 and 100 mg/kg/day, respectively. Furthermore, in pulmonary colonization assay, MP exhibit the inhibitory effect of tumor metastasis. From these results, it was concluded that MP had antitumor and anti-metastatic activity suggesting its application for the prevention and treatment of cancer.

To evaluate the antitumor activity of Kamisagoonjatang(KST), Kami-jihwangtang (KJT) and Kamigoonjajihwangtang(KKJT), studies were done experimentally. The results were obtained as follows: 1. In cytotoxicity against B16-F10, HT1080, SNU, and L1210, con-centration inhibiting cell growth up to below 50% of control was recognized at $10^{-3}g/ml$ of KKJT. 2. In cytotoxicity against A549, SK-OV-3, XF498 and HCT15, concentration inhibiting cell growth up to below 30% of control was over $400{\mu}g/ml$ of KKJT only and also over $200{\mu}g/ml$ against SK-MEL-2. 3. In Inhibitory effect on activity of DNA topoisomerase I, the $IC_{50}$ was shown $200-400{\mu}g/m{\ell}$, of KST, over $400{\mu}g/m{\ell}$ of KJT and $100-200{\mu}g/m{\ell}$ of KKJT. 4. The T/C% was 122.8 in KJT, 127.4 in KST and 158.4 in KKJ-Ttreated group in S-180 bearing ICR mice. 5. In hematological changes in S-180 bearing ICR mice, numbers of WBC were decreased significantly in KJT and KKJT treated groups as compared with control, whereas those of platelet were increased with no significance in all groups as compared with control. From above results it was concluded that KKJT could be usefully applied for the prevention and treatment of cancer.

Three diterpenes (1, 8, and 9), three triterpenes (3, 4, and 7), one saponin (11), four sterols (2, 5, 6, and 12), and one cerebroside (10) were isolated from the EtOH extract of the aerial parts of Aralia cordata by repeated silica gel column chromatography. Their chemical structures were identified by comparing their physicochemical and spectral data with those published in literatures. All isolated compounds were evaluated for their cytotoxicity against L1210, K562, and LLC tumor cell lines using MTT assay. Of which, $3{\beta},5{\alpha}-dihydroxy-6{\beta}-methoxyergosta-7,22-diene$ (6) showed a potent cytotoxicity against all cell lines with $IC_{50}$ values of 11.7, 11.9, and $15.1\;{\mu}M$, respectively, while compounds 1, 5, and 11 showed a moderate or weak cytotoxicity. These isolates were also examined for their inhibitory activity against COX-1 and COX-2. Although most compounds, except for 2, 10, and 12, showed a strong inhibitory activity against COX-1, they exhibited a moderate or weak inhibitory activity against COX-2.

A new lectin was partially purified from starfish,Asterina pectinifera by means of physiological saline extraction, salt fractionation, ion exchange chromatography and hy droxyapatite chromatography, and it was named APL. The biochemical properties of the APL were characterized. In addition, its effects on lymphocyte mitogenicity and cancer cell agglutinability were tested. The APL agglutinated nonspecifically human erythrocytes and rabbit blood cells. Agglutinability was decreased to 30% of control activity below pH 5 and above pH 9 and was relatively unstable at increasing temperatures above 60$^{\circ}C$. The activity was reduced by addition of two kinds of metal ions, $Ba^{2+},\;Mn^{2+}$ and chelating agent, EDTA. APL was proved to be glycoproteins containing 9% sugars. For carbohydrate specificity, it was found that the activity of APL was inhibited by D(+)-glucosamine, D(+)-galactosamine, stachyose, N-acetyl-galactosamine and methyl-${\alpha}$-D-galactopyranoside among 35 sugars tested. In amino acid composition, the contents of acidic amino acids such as aspartic acid and glutamic acid were relatively high. This result suggest that the isoelectric point would be in a lower range. APL was found that it promotes the division of human lymphocytes. APL was proved to be a potent agglutinin for cancer cells such as HeLa, L929 and L1210 cells. Significant changes on the HeLa cell surfaces affected by APL were observed under the electron microscope.
