Hydrogen gas restores exhausted CD8+ T cells in patients with advanced colorectal cancer to improve prognosis

MHID-0370162PMID: 305427402019Oncology Reports

Junji Akagi, Hideo Baba

Exhausted cluster of differentiation (CD)8+ T cells lose immunological activity due to mitochondrial dysfunction caused by peroxisome proliferator‑activated receptor γ coactivator 1α (PGC‑1α) inactivation, resulting in a poor prognosis in patients with cancer. As hydrogen gas was recently reported to activate PGC‑1α, the present study investigated whether it restores exhausted CD8+ T cells to impr

Quantification of hydrogen production by intestinal bacteria that are specifically dysregulated in Parkinson’s disease

MHID-67149392018PLoS ONE

Anzu Suzuki, Mikako Ito, Tomonori Hamaguchi, Hiroshi Mori, Yuka Takeda, Ryuko Baba, et al.

Oral administration of hydrogen water ameliorates Parkinson’s disease (PD) in rats, mice, and humans. We previously reported that the number of putative hydrogen-producing bacte- ria in intestinal microbiota is low in PD compared to controls. We also reported that the amount of hydrogen produced by ingestion of lactulose is low in PD patients. The decreased hydrogen production by intestinal microb

Daily ingestion of alkaline electrolyzed water containing hydrogen influences human health, including gastrointestinal symptoms

MHID-6786572PMID: 307136692018Medical Gas Research

In Japan, alkaline electrolyzed water (AEW) apparatus have been approved as a medical device. And for the patients with gastrointestinal symptoms, drinking AEW has been found to be effective in relieving gastrointestinal symptoms. But some users of AEW apparatus do not have abdominal indefinite complaint. Little attention has been given to the benefit for the users which have no abdominal indefini

Nai-Ying Shen, Jian-Bin Bi, Jing-Yao Zhang, Si-Min Zhang, Jing-Xian Gu, Kai Qu, et al.

AIM To investigate the therapeutic effect of hydrogen-rich water (HRW) on inflammatory bowel disease (IBD) and to explore the potential mechanisms involved. METHODS Male mice were randomly divided into the following four groups: control group, in which the mice received equivalent volumes of normal saline (NS) intraperitoneally (ip); dextran sulfate sodium (DSS) group, in which the mice received NS

Takafumi Ushida, Tomomi Kotani, Hiroyuki Tsuda, Kenji Imai, Tomoko Nakano, Shima Hirako, et al.

Oxidative stress plays an important role in the pathogenesis of preeclampsia. Recently, molecular hydrogen (H2) has been shown to have therapeutic potential in various oxidative stress-related diseases. The aim of this study is to investigate the effect of H2 on preeclampsia. We used the reduced utero-placental perfusion pressure (RUPP) rat model, which has been widely used as a model of preeclamps

Administration of Hydrogen-Rich Saline in Mice with Allogeneic Hematopoietic Stem-Cell Transplantation

MHID-29976812015Medical Science Monitor

Lijuan Yuan, Xiaoping Chen, Liren Qian, Jianliang Shen, Jianming Cai

Hydrogen, as a novel antioxidant, has been shown to selectively reduce the level of hydroxyl radicals and alleviate acute oxidative stress in many animal experiments. Hydrogen-rich saline provides a high concentration of hydrogen that can be easily and safely applied. Allogeneic hematopoietic stem-cell transplantation (HSCT) has been the most curative therapy for hematological malignancies. Howeve

Beneficial biological effects and the underlying mechanisms of molecular hydrogen - comprehensive review of 321 original articles

MHID-7479916PMID: 264839532015Medical Gas Research

Masatoshi Ichihara, Sayaka Sobue, Mikako Ito, Masafumi Ito, Masaaki Hirayama, Kinji Ohno

Therapeutic effects of molecular hydrogen for a wide range of disease models and human diseases have been investigated since 2007. A total of 321 original articles have been published from 2007 to June 2015. Most studies have been conducted in Japan, China, and the USA. About three-quarters of the articles show the effects in mice and rats. The number of clinical trials is increasing every year. I

Multiple Effects of Molecular Hydrogen and its Distinct Mechanism

MHID-8734083PMID: 342834352014Journal of Neurological Disorders

Mami Noda, Kyota Fujita, Ikuroh Ohsawa, Masafumi Ito, Kinji Ohno

Molecular hydrogen (H2) has been reported to be effective for a variety of disorders and its effect has been ascribed to a selective scavenge of hydroxyl radicals (•OH) at the beginning. Consumption of H2 was either by inhalation, drinking H2-containing water (H2 water), or infusion of H2-containing saline. Among various disorders, animal model of ischemic injury and Parkinson’s disease showed sig

Hydrogen as a New Class of Radioprotective Agent

MHID-2487803PMID: 306788962013International Journal of Biological Sciences

Liren Qian, Jianliang Shen, Yunhai Chuai, Jianming Cai

It is well known that most of the ionizing radiation-induced damage is caused by hydroxyl radicals (·OH) follows radiolysis of H2O. Molecular hydrogen (H2) has antioxidant activities by selectively reducing ·OH and peroxynitrite(ONOO-). We firstly hypothesized and demonstrated the ra-dioprotective effect of H2 in vitro and in vivo, which was also repeated on different experimental animal models by

Radioprotective effect of hydrogen in cultured cells and mice

Liren Qian, Fei CAO, Jianguo Cui, Yuecheng Huang, Xiaojian Zhou, Shulin Liu, et al.

It has been demonstrated that hydrogen can selectively reduce hydroxyl and peroxynitrite in vitro. Since most of the ionizing radiation-induced cellular damage is caused by hydroxyl radicals, this study was designed to test the hypoth- esis that hydrogen may be an effective radioprotective agent. This paper demonstrates that treating cells with hydrogen before irradiation could signifi cantly inhib

The Immunological Effects of Electrolyzed Reduced Water on the Echinostoma hortense Infection in C57BL/6 Mice

MHID-1488636PMID: 192522952009Biological & Pharmaceutical Bulletin

Kyu Jae LEE, Dan JIN, Byung Soo CHANG, Yung Chien TENG, Dong Heui KIM

Electrolyzed reduced water (ERW) is widely used for drinking by people in Asia. The purpose of this study was to examine the immunological effect of ERW on the immunity of animals by supplying ERW to C57BL/6 mice infected with Echinostoma hortense metacercariae. In the non-infected groups, interleukin (IL)-4 (p0.001), IL-5, IL-10, IL-1b, tumor necrosis factor (TNF)-a and immunoglobulin (Ig) A exp
