From our hospital, a doctor-helicopter flew to the staging care unit at Hanamaki airport with two members of the disaster medical assistance team (DMAT), one of whom was an anesthesiologist. The helicopter carried ten patients by nine flight missions, who were the victims of tsunami after the earthquake.

Locational characteristics of the increasing number of forensic autopsy cases in Kyoto, Japan.

In Japan, the definition of unnatural death is not prescribed in law. However, a legal judgment recently defined unnatural death as all deaths, excluding natural deaths and deaths from diseases. Legally, unnatural deaths must be reported to the police.

Soluble β-glucan from Grifola frondosa induces proliferation and Dectin-1/Syk signaling in resident macrophages via the GM-CSF autocrine pathway.

MD-Fraction, a highly purified, soluble β-(1,3) (1,6)-glucan obtained from Grifola frondosa (an oriental edible mushroom), has been reported to inhibit tumor growth by modulating host immunity. β-Glucan, a major component of the fungal cell wall, is generally recognized by PRRs expressed on macrophages and DCs, such as Dectin-1, and the ability of β-glucans to modulate host immunity is influenced by their structure and purity. Most cellular studies have used particulate β-glucans, such as yeast zymosan (crude β-glucan) and curdlan (purified β-glucan).

Monocyte and T-cell responses to exercise training in elderly subjects.

The purpose of this study was to examine the effects of exercise training on age-related impairment of immune parameters related to T-cell activation in elderly individuals. Twenty-four elderly subjects were assigned to an exercise training group (EXC: 3 men, 9 women; age 61-76 years) or a nonexercise control group (CON: 4 men, 8 women; age 62-79 years). Subjects in EXC participated in exercise sessions 2 d·wk(-1) for 12 weeks.

A polysaccharide extracted from Grifola frondosa enhances the anti-tumor activity of bone marrow-derived dendritic cell-based immunotherapy against murine colon cancer.

We previously isolated the novel heteropolysaccharide maitake Z-fraction (MZF) from the maitake mushroom (Grifola frondosa), and demonstrated that MZF significantly inhibited tumor growth by inducing cell-mediated immunity. In this study, we demonstrated that MZF upregulated the expression of CD80, CD86, CD83, and MHC II on bone marrow-derived dendritic cells (DCs) and significantly increased interleukin-12 (IL-12) and tumor necrosis factor-alpha production by DCs in a dose-dependent manner. MZF-treated DCs significantly stimulated both allogeneic and antigen-specific syngenic T cell responses and enhanced antigen-specific interferon-gamma (IFN-gamma) production by syngenic CD4(+) T cells; however, MZF-treated DCs did not affect IL-4 production.

Parathyroid hormone-related protein has an anorexigenic activity via activation of hypothalamic urocortins 2 and 3.

Cancer cachexia is reported to be a major cause of cancer-related death. Since the pathogenesis is not entirely understood, only few effective therapies have been established. Since myriad tumors produce parathyroid hormone-related protein (PTHrP), plasma concentrations of PTHrP are increased in cancer cachexia.

Potential antitumor activity of a low-molecular-weight protein fraction from Grifola frondosa through enhancement of cytokine production.

Edible mushrooms contain an abundance of immune-enhancing nutritients. Some of these compounds, referred to as biological response modifiers (BRMs), have been used in biological therapies for cancer treatment. We obtained a low-molecular-weight protein fraction (MLP-Fraction) from the fruiting body of the maitake mushroom Grifola frondosa by multiple sequential steps, including ethanol precipitation, DEAE-exchange chromatography, and gel filtration.
