BACKGROUND: In chemical pleurodesis for managing pulmonary air leak, tetracycline derivatives are commonly used, and their effectiveness has been established in many studies. Recently, a Viscum album extract was used in chemical pleurodesis. We compared the effects of V. album with those of a tetracycline derivative (doxycycline) to demonstrate the therapeutic effectiveness of the V. album extract in chemical pleurodesis for managing pulmonary air leak. METHODS: Between October 2010 and October 2016, chemical pleurodesis was performed using doxycycline in 40 patients and the V. album extract in 37 patients. Thirty-three patients were in the postoperative state after pulmonary resection, and 44 patients suffered from spontaneous pneumothorax. RESULTS: No statistically significant difference in the success rate was observed between the 2 groups (V. album extract and doxycycline). In both groups, chest pain was the most common complication. More patients in the doxycycline group complained of severe chest pain (42.1% vs. 13.5%, p=0.006). In the V. album extract group, 24.3% of the patients required a chest tube to drain the pleural effusion after cessation of the air leak (doxycycline group: 5%, p=0.022). Further, the amount of pleural effusion drained on the day after the last chemical pleurodesis in the V. album extract group was greater than that in the doxycycline group (162.2±170.2 mL vs. 97.0±77.2 mL, p=0.032). All patients were discharged from the hospital without complications after pleural effusion drainage. CONCLUSION: Considering that treatment using the V. album extract was less painful, V. album might be a feasible option for chemical pleurodesis. However, pleural effusion should be monitored carefully when using V. album extract for treating patients suffering from air leak.

A 52-year-old male patient who underwent multiple wedge resections experienced postoperative acute respiratory distress syndrome in both lungs after Viscum album pleurodesis. Despite initial rapid deterioration in clinical condition and rapid progression of bilateral lung infiltration, he exhibited a relatively smooth clinical recovery with marked response to glucocorticoid treatment. Our case report suggests that care must be taken to guard against the development of acute respiratory complications in the use of Viscum album for pleurodesis. However, in view of the clinically benign course, initial aggressive management of complications can prevent suffering and sequelae.

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...

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.

BACKGROUND: Malignant pleural effusion is a common clinical problem in neoplastic patients. With the diagnosis of a malignant pleural effusion, palliative therapy was done. One of the treatments was a chemical pleurodesis. Talc was the most commonly used a sclerosing agent, but the quality of patient's life was not improved. We was evaluated by other agents such as Viscum album for relief of malignant pleural effusion. MATERIAL AND METHOD: From November 2001 to October 2003, 17 patients who underwent to chemical pleurodesis for the malignant pleural effusion. We compared the talc (group I: 10 patients) and Viscum album (group II: 7 patients). We analysed them retrospectively in term of various factors and results. RESULT: There were no significant differences between group I and group II in the sex ratio, mean age, origin of primary cancer and site, but, group I had higher successful rate (80%:71%) than group II. Group II had better length of chest tube stay after procedure, Karnofsky performance and recurrence than group I. The failed treatement group was related to the pleural fluid pH and interval of initial chemical pleurodesis after thoracostomy. CONCLUSION: Although the chemical pleurodesis with Viscum album was slightly lower than talc in the successful rate, there was an alternative method instead of the chemical pleurodesis with talc to improve the patient's quality of life in malignant pleural effusion.

The present study aims to investigate the effect of methanol extract of Korean mistletoe (KM; Viscum album var. coloratum), on amyloid beta protein (Abeta) (25-35), a synthetic 25-35 amyloid peptide, -induced neurotoxicity in cultured rat cerebral cortical neurons and memory impairment in mice. Exposure of cultured neurons to 10 microM Abeta (25-35) for 24 h induced a neuronal cell death, which was measured by a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assay and Hoechst 33342 staining. KM (10, 30 and 50 microg/ml) significantly inhibited the Abeta (25-35)-induced apoptotic neuronal death. KM (50 microg/ml) inhibited 10 microM Abeta (25-35)-induced elevation of intracellular calcium concentration ([Ca2+]i), which was measured by a fluorescent dye, Fluo-4 AM. Glutamate release into medium and generation of reactive oxygen species (ROS) induced by 10 microM Abeta (25-35) were also inhibited by KM (10, 30 and 50 microg/ml). These results suggest that KM may mitigate the Abeta (25-35)-induced neurotoxicity by interfering with the increase of [Ca2+]i and then inhibiting glutamate release and generation of ROS in cultured neurons. In addition, orally administered KM (25 and 50 mg/kg, 7 days) significantly prevented memory impairment induced by intracerebroventricular injection of Abeta (25-35) (8 nmol). Taken together, it is suggested that anti-dementia effect of KM is due to its neuroprotective effect against Abeta (25-35)-induced neurotoxicity and that KM may have therapeutic role in prevention of the progression of Alzheimer's disease.

viscum album extracts which are known to have very little side effect and have been used in Europe for almost 80 years. In this study, I focused on screening anti-canceral activities of ABNOBAviscum. in vitro and in vivo, which is viscum album extracts that was proved to act anti-cancerally on other solid tumors. In vivo study, HN 22 cell lines were xenografted in nude mice. After the growth of tumor mass was observed, ABNOBAviscum. was directly injected on the tumor mass. The experimental group and the control group were compared and divided at week 1, 2, 4, 6, 8. The results were obtained as following : The growth of the cells was decreased according to the ABNOBAviscum. concentrations, especially in the NHOK. According to the MTT assay, HN 22 cell lines showed relative drug resistancy above the 100 microgram/ml concentrations of ABNOBAviscum.. The visual inspection of the experimental group showed that the volume of the gross tumor mass was significantly decreased at week 2 via statistics, and tumor mass was subsided at week 6. Microscopic view of the xenografted tumor mass showed well differentiated squamous cell carcinoma. At week 6, microscopic view of the experimental group showed fibrosis, inflammatory cell invasions and degenerative calcifications. After the ABNOBAviscum. injection, scar tissue was seen widely at week 8. Ki-67 index was considerably decreased at week 2 in the experimental group. Immunostainability of Bcl-2 index was decreased in the experimental group at week 2. There was no difference in density of blood capillary between the control and the experimental group. In this study, ABNOBAviscum. showed the excellent anti-canceral activity against HN 22 cell lines and was proved to induce cell death in oral squamous cell carcinoma cells through apoptosis and necrosis.]]>
