Here’s a link to an article from BBC about the health connection between zebrafish and humans as it relates to asthma. Evidently, whenever both humans and these fish experience a tissue injury the body sends hydrogen peroxide to the area which is a signal for the white blood cells to come to the rescue and perform their healing magic. As referred to in the article, the studies seem to indicate that

In the human body, hydrogen peroxide is produced primarily in three places – the lung, gut and thyroid gland.

Professor Mitchison said: “Perhaps in conditions like asthma, the lung epithelia is producing too much hydrogen peroxide because it’s chronically irritated, which, if our findings translate to humans, would explain inappropriate levels of white blood cells.

“This is certainly a question worth pursuing.”

Dr Leslie Knapp, of the University of Cambridge, said: “Although hydrogen peroxide is routinely used for wound cleaning and prevention of infection, some laboratory-based studies suggest that hydrogen peroxide can have a negative effect on the healing process by interfering with the activities of cells that form connective tissue.

“This new study, involving a living organism, could provide new insight on immune function and the causes of various inflammatory diseases in humans.”

Dr Elaine Vickers, of the charity Asthma UK, said hydrogen peroxide levels did appear to be higher in the lungs of people with asthma, but it was not clear why.

“We welcome any research that increases our understanding of the role that hydrogen peroxide plays in the body.

“This could shed light on the causes of asthma symptoms and potentially lead to new avenues for creating future asthma treatments.”

Interesting, especially when you live with two people who are asthmatic.  Who would have thought that people and fish are so similar.
