Background: The objective of this study was to determine the effects of Daegangwhal-Tang (DGHT) hot aqueous extract on production of inflammatory mediators and antioxidants in RAW 264.7 macrophage. Methods: DGHT was extracted with water, filtered, concentrated and freeze-dried to perform. Cytotoxicity of DGHT extract was performed by MTT assay. Activated macrophages were treated with varying concentrations of DGHT extract (10, 50, 100 and $200{\mu}g/mL$), and nitric oxide (NO) and prostaglandin E2 ($PGE_2$) concentrations were measured to detect anti-oxidative effects. Interleukin-6 (IL-6), interleukin-1 beta ($IL-1{\beta}$) and tumor necrosis factor-alpha($TNF-{\alpha}$) concentrations were also measured to detect inflammatory responses to DGHT Results: Cytotoxicity of DGHT extract at concentrations of 10, 50, 100 and $200{\mu}g/mL$ were not observed. NO production was significantly decreased in the DGHT hot aqueous extract $200{\mu}g/mL$ concentration group. $PGE_2$, IL-6, $IL-1{\beta}$ and $TNF-{\alpha}$ production was significantly decreased in the DGHT hot aqueous extract 100 and $200{\mu}g/mL$ concentration groups. DGHT hot aqueous extract appeared to have DPPH free radical scavenging capability at all of concentrations, but did not exceed 50%. Conclusion: These results suggest that DGHT hot aqueous extract has concentration-dependent anti-inflammatory and anti-oxidative effect.

To investigate the immunostimulating and anticancer activities from hot water extract of Capsosiphon fulvescens, tumor cell toxicity, sarcoma-180 growth inhibition activity, complement system-activity, intestinal immune system and oral toxicity were performed. The extract of Capsosiphon fulvescens was prepared by hot water and precipitated by using ethanol. Partially purified extract (CFE) was obtained after dialysis and ultrafiltration. The polysaccharide compositions consisted of xylose(19.1%), fucose(15.3%), mannose(4.2%) and galactose(7.9%). The tumor cell toxicity of CFE slightly showed at high concentrations of 10-30 ${\mu}g/ml$, but inhibition ratio against mouse solid tumor was more increased for CFE of 40.1-59.4% than the control. Blood leukocyte counts increased to a maximum of 83% including liver, spleen and thymic of mouse. Immunoglobulin A binding amounts showed a high level of CFE of $2,454{\pm}113.8-2,670{\pm}133.1{\mu}g/mg$ in comparison with the control of $2,092{\pm}123.0{\mu}g/mg$. Acute toxicity of CFE was not detected at the concentration of 2,000 mg/kg in normal mouse.

A 36-year-old man visited Yeungnam University Hospital with a sudden onset of palpitation, headache, and was found to be hypertensive. Chest radiography showed a 6 cm sized mass lesion on the posterior mediastinum. A biochemical study showed elevated levels of catecholamines. An I-123 metaiodobenzylguanidine scan revealed a hot uptake lesion on the posterior mediastinum. The patient was prepared for surgery with ${\alpha}$ and ${\beta}$ blocking agents. Two months later, we removed the tumor successfully. A histological study proved that the resected tumor was mediastinal pheochromocytoma. Functional mediastinal pheochromocytomas are rare. Therefore, we reported the case with a literature review.

Malignant glioma, also known as brain cancer, is the most common intracranial tumor, having an extremely high mortality and recurrence rate. The survival rate of the affected patients is very low and treatment is difficult. Hence, growth inhibition of glioma has become a hot topic in the study of brain cancer treatment. Among the various isothiocyanate compounds, it has been confirmed that benzyl isothiocyanate (BITC) can inhibit the growth of a variety of tumors, including leukemia, glioma and lung cancer, both inside and outside the body. This study explored inhibitory effects of BITC on human glioma U87MG cells, as well as potential mechanisms. It was found that BITC could inhibit proliferation, induce apoptosis and arrest cell cycling of U87MG cells. In addition, it inhibited the expression of SOD and GSH, and caused oxidative stress to tumor cells. Therefore, it is believed that BITC can inhibit the growth of U87MG cells outside the body. Its mechanism may be related to the fact that BITC can cause oxidative stress to tumor cells.

Hot water-extracts prepared from Cordyceps militaris of silkworm pupa (CMP) or Cordyceps militaris of silkworm larva (CML) were tested for tumor growth inhibitory and immunomodulatory activities in ICR mice bearing sarcoma-180 cells solid tumor, and compared with those of the known compound, cordycepin, found in Cordyceps militaris. Mice were subcutaneously injected with sarcoma-180 cells, and i.p. injected with either saline (Control), 50 mg/kg or 100 mg/kg of CMP (CMP50 or CMP100, respectively), or CML (CML50 or CML100, respectively), or 1 or 2 mg/kg of cordycepin (C1 or C2, respectively) for 10 days. Mice injected with CMP50 or CMP100 showed a 47.3% or 57.6% inhibition in the solid tumor growth (P<0.05), while those injected with CML50 or CML100 exhibited a 35.5% or 37.1% reduction (p<0.05) in solid tumor size compared to the value for control mice treated with saline. Animals injected with corcycepin showed a 26∼30% inhibition in the solid tumor growth (P<0.05). Mice bearing solid tumor and injected with CMP or CML showed a significantly increased thymus weight (38∼44% increase), lymphocyte percentages of CD4+ T-cell, CD8+ T-cell, and NK-cell (63∼110% increase) in the spleen, and interleukin-2 excretion (33∼51% increase) by the isolated splenocytes compared to those in control mice (p<0.05). These results indicate that the anti-tumor activity of hot water extracts of Cordyceps militaris, raised on both silkworm pupa and silkworm larva, appears to be associated with their immunomodulatory activity, and these activities found in Cordyceps militaris are superior to those for the single compound, cordycepin.

$Elfvingia$ $applanata$, a medicinal mushroom belonging to Basidiomycota, has been used in the effort to cure cancers of the esophagus and stomach, and is also known to have inhibitory effects on hepatitis B virus infection. The hot water soluble fraction (as Fr. HW) was extracted from fruiting bodies of the mushroom. $In$ $vitro$ cytotoxicity tests showed that hot water extract was not cytotoxic against cancer cell lines such as Sarcoma 180, HT-29, HepG2, and TR at concentrations of 10-2,000 ${\mu}g/mL$. Intraperitoneal injection with Fr. HW resulted in a life prolongation effect of 45.2% in mice previously inoculated with Sarcoma 180. Treatment of Fr. HW resulted in a 2.53-fold increase in the numbers of murine spleen cells at a concentration of 50 ${\mu}g/mL$, compared with control. Incubation of murine spleen cells with Fr. HW at a concentration of 500 ${\mu}g/mL$ resulted in improved immune-potwntiating activity of B lymphocytes through an 8.3-folds increase in alkaline phosphatase activity, compared with control. Fr. HW generated 12.5 ${\mu}M$ of nitric oxide (NO) when cultured with RAW 264.7, a mouse macrophage cell line, at the concentration of 50 ${\mu}g/mL$, while lipopolysaccharide, a positive control, produced 15.2 ${\mu}M$ of NO. Therefore, the results suggested that antitumor activities of Fr. HW from $E.$ $applanata$ might, in part, be due to host mediated immunostimulating activity.

The relationship between angiographic findings and those of $^{67}Ga$ scan was evaluated in 30 patients with primary hepatocellular carcinoma diagnosed by either pathological examination or laboratory, radiologic findings. Twenty-three cases revealed hot activities on $^{67}Ga$ scan and definite tumor stains on angiography. Main findings of $^{67}Ga$ scans of 7 cases were isoactivity in 5 and cold area in 2, 5 of which revealed faint or no tumor stain on angiography. Cold areas within the primary hepatocellular carcinoma were noted in 9 cases by $^{67}Ga$ scan. In 6 cases these were due to tumor necrosis. Remaining 3 cases had arterioportal shunt, portal vein thrombosis and one had necrosis as well. These results indicate that gallium uptake of primary hepatocellular carcinoma seems to be relatively correlated with tumor stains on angiography. It is well known that the necrotic portion of primary hepatocellular carcinoma does not uptake gallium and it's the main cause of cold areas on $^{67}Ga$ scan. And we suspect that the hemodynamic changes of primary hepatocellular carcinoma such as large arterioportal shunt, portal vein thromosis may cause the decreased activity on $^{67}Ga$ scan.

The aim of this study was to determine the in vitro anti-inflammatory effect of hot water extract from Cordyceps militaris fruiting bodies (CMWE) on lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production, tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin-6 (IL-6) release in RAW 264.7 cells. The treatment of macrophages with various concentrations of hot CMWE significantly reduced LPS-induced production as well as NO, TNF-$\alpha$ and IL-6 secretion in a concentration-dependent manner. These results suggest that CMWE have potent inhibitory effects on the production of these inflammatory mediators.

The study was performed to investigate the biological activity of Enteromorpha intestinalis. In order to examine its blood anti-coagulant effects, Enteromorpha intestinalis was extracted with cold water, methanol, hot water, HCl and NaOH. In general, the alkali extract of Enteromorpha intestinalis was approximately 17 times stronger than the control. The anti-cancer effects of select extracts(methanol, hot water, 0.1 N NaOH, 1 N NaOH) were determined in human melanoma cells(Bl6/F10), fibrosarcoma cells(HTl080) and breast cancer cells(MCF7) by MTT assay. With the treatment of 250 ${\mu}g/m{\ell}$ of methanol extracts. HT1080, B16/F10 and MCF7 cell viabilities significantly decreased to 8.06%, 3.62% and 10.10%, respectively. Thus these results strongly support the possibie use of Enteromorpha intestinalis as a functional materials.
