Decompression comparison of helium and hydrogen in rats

Year Published: 1997

The hypothesis that there are differences in decompression risk between He and H2 was examined in 1,607 unanesthetized male albino rats subjected to dives on 2% O2-balance He or 2% O2-balance H2 (depths < or = 50 ATA, bottom times < or = 60 min). The animals were decompressed to 10.8 ATA with profiles varying from rapid to slow, with up to four decompression stops of up to 60 min each. Maximum ...

Response of five established solid transplantable mouse tumors and one mouse leukemia to hyperbaric ...

Year Published: 1978

A variety of transplantable mouse tumors were used in experiments to determine the efficacy of hyperbaric hydrogen treatment. After 7 continuous days of hyperbaric hydrogen treatment, no inhibition of tumor growth was observed.

Hyperbaric hydrogen therapy: A possible treatment for cancer

Year Published: 1975

Hairless albino mice with squamous cell carcinoma were exposed to a mixture of 2.5 percent oxygen and 97.5 percent hydrogen at a total pressure of 8 atmospheres for periods up to 2 weeks in order to see if a free radical decay catalyzer, such as hydrogen, would cause a regression of the skin tumors. Marked aggression of the tumors was found, leading to the possibility that hyperbaric hydrogen ...

Production and Excretion of Hydrogen Gas in Man

Year Published: 1969

Technics employing intestinal infusions of gas were used to study H2 production in the human intestine. The volume of H2 in the bowel of 10 normal subjects varied from 0.06 to 29 ml. H2 production, which averaged 0.24 ml per minute in the fasting state, sharply increased after intestinal instillation of lactose to a mean peak rate of 1.6 ml per minute. Ingestion of food also increased H2 ...
