2.Complementary Therapies and Cancer Treatment.
Journal of the Korean Medical Association 2008;51(5):427-434
Many patients with cancer use complementary medicine that is used together with conventional medicine. The widespread use of complementary therapies in cancer patients has major implications for research and clinical practices. Some complementary therapies, such as polysaccharide K, Astragalus membranaceus and A. mistletoe, may offer therapeutic benefits for patients with cancer. However, others did not show significant clinical effects for cancer treatment. Therefore, it is important for physicians to communicate openly with cancer patients about the use of complementary therapy. In order to encourage open communications with their patients, physicians should be knowledgeable about the most commonly used remedies, or at least they should be able to direct patients to reliable sources of information.

BACKGROUND: The immunomodulatory effects of Korean mistletoe (Viscum album Coloratum) on the innate immune responses of eel (Anguilla japonica) were studied. METHODS: Mistletoe, Freund's complete adjuvant (FCA), or phosphate-buffered saline (PBS) as a control was injected into eel peritoneal cavities. RESULTS: Nitroblue tetrazolium (NBT)-positive cells in the head kidney of eel were significantly augmented by the second day post-injection of mistletoe. Reactive oxygen intermediates (ROI) were more produced in mistletoe-injected fish kidney leucocytes than in FCA-injected ones. The level of lysozyme activity in the serum of fish 2 days after injection with mistletoe was also significantly higher than that in the serum of the control fish. The optimal concentration of mistletoe in inducing the highest serum lysozyme activity was revealed to 500microgram/200 g of fish. In phagocytic activity assay, mistletoe-sensitized eel kidney phagocytes captured more zymosan than did the control fish. CONCLUSION: Korean mistletoe appeared to be a good activator of the non-specific immune responses of eel.

This study was performed to investigate mistletoe extract-induced apoptosis in oral squamous cell carcinoma. In vivo study, HN22 cells were xenografted in nude mice. After tumor was experimentally induced, mistletoe extract was directly injected on the tumor mass. The specimens were evaluated using light and transmission electron microscopes. In vitro study, HN22 cells were cultured and exposed to mistletoe extract. The cells were evaluated using transmissin electron microscope. To evaluate apoptotic cells, flow cytometric analysis was done. The results were obtained as follows: 1. Light microscopic view of tumor mass showed necrosis at 2-4 weeks. 2. Transmission electron micrographs of tumor mass showed apoptosis and necrosis. 3. In TEM view of cell lines, necrosis and apoptosis were shown with mistletoe extract at 300microgram/ml, apoptosis was shown with mistletoe extract at 100microgram/ml. 4. In flow cytometric analysis, early and late apoptosis was shown when using caspase-3Ab and annexin-V, but no significant change was noted when using mebstain and Apo2.7 Ab. In this study, mistletoe extract induced necrosis and apoptosis in the tumor mass was induced by HN22 cells, early and late apoptosis in vitro study. Mistletoe extract was likely to induce cell death in oral squamous cell carcinoma through apoptosis.

5.The Effect of intraperitoneal instillation of Mistletoe extract during the diagnostic laparoscopy for pain of endometriosis.
Korean Journal of Obstetrics and Gynecology 2005;48(4):1004-1008
OBJECTIVE: Immune alternation is related to the pathogenesis and progression of endometriosis. Helixor-A, mistletoe extract, has been known that it has immune modulation effect. Therefore the purpose of this study is to determine the effects of Helixor-A for pain of endometriosis by intraperitoneal instillation of mistletoe extract during the diagnostic laparoscopy. METHODS: Among the paitients who visited to outpatient clinic due to chronic pelvic pain, 30 patients who had laparoscopically-confirmed endometriosis were included in this study. Helixor-A 5 mg was instilled into the posterior cul-de-sac during the diagnostic laparoscopy. Before diagnostic laparoscopy and one month after laparoscopy, the patients recorded pain scores. RESULTS: In 11 of 30 patients (36.7%), pelvic pain of endometriosis improved after laparoscopy. In 2 of 30 patients, the side-effect of Helixor- A appeared and they were easily controlled by antihistamines. CONCLUSION: The instillation of Helixor-A during diagnostic laparoscopy, that is essential for confirmation of endometriosis, may be helpful as a supportive treatment for treatment of pelvic pain due to endometriosis with classical treatment such as GnRH agonist therapy.

Immunological effect of the extract (KM-110) from Korean mistletoe (Viscum album coloratum) was examined. Lymphocytes obtained from KM-110-administrated mice showed increased responsiveness to mitogens, concanavalin-A (Con.A) and lipopolysaccharide (LPS). In order to study cytokine induct ability of the KM-110, macrophages from the Balb/c mice were cultivated in the medium containing the extract. the macrophages were shown to induce secretion of tumor necrosis factor-alpha (TNF-alpha), interleukin 1 and 6 (IL-1, IL-6) and interferon-gamma (INF-gamma). We then tested antitumor activity of the macrophages activated by the KM-110. Peritoneal macrophages harvested from the KM110-treated Balb/c mice exhibited cytotoxicity against the syngeneic 3LL carcinoma cells. ...continue...

Korean Journal of Obstetrics and Gynecology 2005;48(5):1288-1293
OBJECTIVE: Chronic pelvic pain is pelvic pain which is not completely controlled by classical treatments. In many reports, immune alternation is related to original diseases that induce the chronic pelvic pain. Mistletoe extract has been known that it has immune modulation effect. Therefore the purpose of this study is to determine the pain-reducing effects of mistletoe extract for chronic pelvic pain that is not controlled by classical treatments. METHODS: The fitty-eight patients who visited to outpatient department of Department of Obstetrics and Gynecology, Chonnam National University Hospital due to chronic pelvic pain. Mistletoe extract (Helixor-A(R)) 5-10 mg was injected subcutaneously 3 times per week for 5 weeks, and the change of pain and short-term side-effects after injections were observed. In patients after 6 month of follow-up, the change of pain and long-term side-effects were also observed. RESULTS: In 2 of 58 patients (0.03%), treatments were discontinued doe to severe general side effect. In 48 of 56 patients (85.7%), chronic pelvic pains were improved. In 40 of 56 patients (69%), mild side effects as like mild itching were appeared and they were easily controlled by anti-histamines and conservative treatments. In 6 months after injection, general itching sensation and easily catched common cold were complaint in 4 of 10 patients. CONCLUSION: The subcutaneous injection of mistletoe extract may effective treatment method for the chronic pelvic pain that is not controlled by classical treatment. However more studies about log-term effect of mistletoe therapy are needed.

BACKGROUND: Korean mistletoe (Viscum album) extract has been found to posses immunostimulatory activity. In this study, Korean mistletoe extract, M11C (non-lectin components), was used to know whether this extract might activate mouse peritoneal macrophages to produce interleukin 1 beta (IL-1 beta). METHODS: Hemagglutination assay was carried out to examine whether M11C contained a lectin or not . To know the effect of M11C on the production of IL-1 beta, the macrophages were treated by the M11C, and then collected the supernatant (M11C stimulated macrophages-conditioned media; MMCM). MMCM was analyzed for the IL-1 beta quantification and mRNA expression by means of ELISA and RT-PCR, respectively. RESULTS: Maximum effective dose and time of M11C on IL-1 beta production from macrophages were 20 micro gram/ml and 8 hours, respectively . This ELISA data was reconfirmed by immunoblotting assay . indicating that M11C is a good candidate for an immunomodulator. The dose and time dependent effect s of M11C on the expression of IL-1 beta mRNA from macrophages was also shown in expression of mRNA detected by RT-PCR. Treatment dose and time for the maximum expression of IL-1 beta mRNA were 20 micro gram/ml and 4 hours, respectively . Maximum gene expression of IL-1 beta was much earlier than maximum production of it. CONCLUSION: As results, Korean mistletoe extract, M11C, may be used for an immunomodulator. This will be able to make up for and solve the problems caused by existent immunoagent with many adverse effects through many other studies in future including one molecule extraction.

PURPOSE: Mistletoe extract was widely used for cancer treatment as complementary or alternative therapy in European area from early twenty century. It is currently used as alternative anti-cancer remedy by piecemeal in domestic medical group, however, the anti-cancer mechanism of mistletoe extract was not known precisely until now. In this study the effect of mistletoe extract on gastric cancer was studied vis cell line experiments. MATERIALS AND METHODS: The SNU719 gastric cancer cell line was used, and ABNOBAviscum-Q and ABNOBAviscum-F were treated to cells as mistletoe extract, or 5-FU and cisplatin were used with mistletoe extract. The cell viability and cell death rate were estimated by CCK-8 assay kit and lactate dehydrogenase (LDH) assay kit in each. Caspase 3 assay kit was used to measure caspase 3 activity. The protein expression amounts of Bcl2, p53, and PTEN were estimated through Western blot analysis. RESULTS: The co-treatments of mistletoe extract Q/F and 5-FU/cisplatin decreased lesser cell viability than only mistletoe treat. Caspase 3 activity was increased 4~6 times in co-treatment of mistletoe extracts and 5-FU than control. Bcl2 protein expression was reduced by mistletoe extracts or anti-cancer drugs, further more, the co-treatment of mistletoe extracts and 5-FU/cisplatin diminished more the expression than only mistletoe treatment. Mistletoe extracts did not affect the protein expressions of p53 and PTEN. CONCLUSION: It was concluded that the anti-cancer mechanism of mistletoe extracts was made by caspase 3 activation and lowered Bcl2 expression, and this apoptosis inducing mechanism was independent to p53.

Immunoadjuvant activities of the extract (KM-110) from Korean mistletoe ( Viscum album coloratum) on the induction of humoral and cellular responses against Keyhole limpet hemocyanim (KLH) as an antigen and allogenic tumor cells were examined. When mice were immunized subcataneously (s.c.) with KLH admixed with KM-110, more than 1000-times higher antibody titers to KLH than those immunized with KLH alone was observed. KM-110 induced high level of KLH- specific IgG1, IgG2a and IgG2b antibodies. In an in vitro analysis of lymphocytes proliferation to KLH on week 4, the splenocytes of mice treated with KLH and KM- 110 exhibited significantly higher proliferating activity than those treated with KLH alone. In addition, the culture supernatnats obtained from the splenocytes of mice treated with both KLH and KM-110 showed high level of IL-2 and IL-4. In the test of cellular immune responses, KM-110 enhanced the DTH reaction to KLH in mice. Furthemore, cytotoxic T-lymphocyte (CTL) activity using an allogenic CTL induction model where C57BL/6 (H-2b) mice were injected with allogenic P815 (H-2d) mastocytoma cells admixed with or without KM-110, mice treated with P815 cells and KM-110 showed higher cytatoxic activity against allogenic tumor cells than those treated without KM-110. This results suggest that KM-110 may possess adjuvant activities to potentially enhance humoral as well as cellular immune responses against antigens.
