University of Nebraska Medical Center researchers have received a four-year,<\/p>\n

$1.7 million grant from the U.S. Department of Defense to develop an efficient<\/p>\n

way to protect humans against the toxic effects of nerve agents used in<\/p>\n

chemical warfare. Nerve agents are chemicals related to the organophosphorus<\/p>\n

group of pesticides, which interfere with the functioning of the nervous<\/p>\n

system.<\/p>\n

The goal of the study is to find a way to treat people who have been<\/p>\n

exposed to chemical warfare nerve agents, which can be fatal or cause extensive<\/p>\n

health damage, said Oksana Lockridge, Ph.D., principal investigator of<\/p>\n

the grant. The Army is very interested in getting a protection against<\/p>\n

chemical warfare agents, because the agents are so easy to make, said<\/p>\n

Dr. Lockridge, associate professor in the UNMC Eppley Institute for Research<\/p>\n

in Cancer and Allied Diseases and department of biochemistry and molecular<\/p>\n

biology.<\/p>\n

The study will use gene and protein therapy, the treatment of disease<\/p>\n

by replacing, altering or supplementing a gene or protein responsible for<\/p>\n

the disease, to better protect against effects of nerve agents. A technique<\/p>\n

being tested through Dr. Lockridges research is administration of a protein<\/p>\n

applied through a skin patch.<\/p>\n

We know the identity of a human enzyme, butyrylcholinesterase, that<\/p>\n

will neutralize any pesticide or chemical warfare agent very effectively<\/p>\n

without being toxic to a person or an animal, Dr. Lockridge said. <\/p>\n

With this protection, you wont even know you got hit with something.<\/p>\n

Butyrylcholinesterase is found in blood, the liver, and other tissues;<\/p>\n

however, its function is not specifically known.<\/p>\n

Breathing 10 milligrams the weight of a grain of rice – of the deadliest<\/p>\n

nerve agent, called VX, can kill in 15 minutes. Symptoms of nerve agent<\/p>\n

exposure include reduced vision, diarrhea, vomiting, paralysis and respiratory<\/p>\n

failure. Ultimately, individuals experience convulsions and go into a coma.<\/p>\n

An antidote kit called the Mark I, distributed to U.S. troops during the<\/p>\n

Gulf War, is currently available for protection against death by nerve<\/p>\n

agent exposure. Dr. Lockridges study is looking for a better alternative.<\/p>\n

Chemical warfare was used in the 1995 Toyko subway terrorist attacks,<\/p>\n

when members of a cult placed sarin gas on the trains, killing 12 and injuring<\/p>\n

more than 5,500.  Agents such as sarin, VX and tabun are inexpensive<\/p>\n

and easy to manufacture and have been used as weapons of terrorism and<\/p>\n

defense mechanisms for third world countries.<\/p>\n

A method must be developed that shields humans from the effects of<\/p>\n

chemical warfare agents and provides medical treatment for those who become<\/p>\n

exposed, she said.<\/p>\n

Dr. Lockridges study also is relevant to Nebraska farmers because of<\/p>\n

the similarity in makeup of chemical warfare agents and pesticides. About<\/p>\n

80,000 cases of pesticide poisoning are reported annually in the United<\/p>\n

States. Common pesticides such as roach and ant killers are in the same<\/p>\n

class of chemicals as the chemical nerve agents.<\/p>\n

With the system of gene and protein therapy currently developed in Dr.<\/p>\n

Lockridges lab, the cost of protecting one person is at least $1 million.<\/p>\n

The researchers are looking for ways to lower the cost so it would be a<\/p>\n

realistic option to protect the general public.<\/p>\n

Co-investigators of the study are Steven Hinrichs, M.D., associate professor<\/p>\n

of pathology and microbiology and director of the Nebraska Public Health<\/p>\n

Laboratory; and Angie Rizzino, Ph.D., professor in the Eppley Institute<\/p>\n

and department of biochemistry and molecular biology.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"
