Another way antibiotics could be helping

Antibiotics have some interesting properties besides killing bugs. Here's one more, and it's one that may be very applicable to us:

Antibiotic Shown to Protect Nerves in Animal Study

LONDON (Reuters) - Antibiotics could one day be used for more than killing bacteria and may help patients suffering from neurological diseases, scientists said on Wednesday.

If a family of antibiotics, which include penicillin, produces the same effect in humans as they did in mice, researchers from Johns Hopkins University in Maryland believe the drugs could help to prevent nerve damage and death in illnesses such dementia, stroke and epilepsy.

"We're very excited by these drugs' abilities," Jeffrey Rothstein, a professor of neurology and neuroscience at the university, said in a statement.

In studies of mice genetically engineered to develop amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease (news - web sites), Rothstein and his team discovered that daily injections of the drug ceftriaxone improved survival and reduced symptoms of the progressive disease that attacks nerve cells in the brain and spinal cord causing paralysis and death.

Ceftriaxone is produced by Roche Holding AG under the brand name Rocephin.

They found that the drug turned on a gene that increased the number of transporters that remove the brain chemical glutamate from nerves. Glutamate usually helps electrical signals travel from one nerve to another but too much of the chemical can kill nerves.

"Because we study ALS, we tested the drugs in a mouse model of that disease, but this is much bigger than ALS. This approach has potential applications in numerous neurological and psychiatric conditions that arise from abnormal control of glutamate," Rothstein, who reported the findings in the science journal Nature, explained.

Although it is early research and clinical trials in humans are needed to prove if the drugs can help patients, the scientists said the results are encouraging despite the fact that the mice treated with the antibiotic were eventually paralyzed.

"If we can find drugs that protect against other causes of nerve death in ALS, the combination might offer a real therapy, much like using drug combinations to treat cancer," said Rothstein

IOW the antibiotics could not completely halt the disease.
