Plants may protect cells against cancer
By Stefani Day Of the Kansan staff
Some plants may offer natural protection against genetic damage, a KU professor of medicinal chemistry said yesterday at the International Conference on Mechanisms of Antimutagenesis and Anticarcinogenesis.
The professor, Lester Mitscher, spoke at the Holiday Inn Holidome, 200 McDonald Drive, to scientists from around the world who have gathered to share information that could increase understanding of how genetic damage, and thus cancer, might be prevented.
Mitscher said that extracts from a wild licorice plant found in Kansas, among other places, reduced mutations in cells in various tests.
This means that some compounds in the extract may be natural cancer-fighting substances.
Mitscher said varieties of the plant had been used in medicine for about 6,000 years and it was still used in medicines to help soothe sore throats.
It is also important commercially, he said, to flavor candy, chewing tobacco and cigars.
"People hear that there are nasty
compounds in the environment," Mitscher said after the meeting. "I hope they take comfort in the fact that there are also protective compounds in the environment, and that's what we're hoping to show."
Another source of natural mutagen-fighting agents is human saliva, according to a scientist from Doshisha University in Kyoto, Japan.
H. Nishioka told the conference that components of saliva made inactive the damage-causing abilities of several carcinogens found in food.
Nishioka said saliva from more than 200 donors had been tested and the inactivating capacities differed widely among individuals. The enzyme activity also tended to decrease in people older than 55 years old.
"But please do not get shocked if you are more than 55 years old," he said. "You can cover by chewing food well."
He suggested chewing each bite of food at least 30 times, which would allow the enzymes in the saliva to be fully activated.
He said the activity of an enzyme in saliva also decreased after strenuous exercise.
"So chew food well and do not get tired too much. Maybe it's important to prevent cancer," he advised.
Gov. John Carlin and a highranking presidential economist will attend an economic outlook conference Oct. 25 at the University of Kansas.

Charles Krider, director of business research at the Institute for Public Policy and Business Research, said the slow economic growth rate in Kansas caused concern.
"It's below the growth rate in the U.S. as a whole," he said. He said employment was predicted not to grow in several industries, such as agriculture, aircraft and automobile manufacturing.
"Kansas has not pursued other areas aggressively," he said. "There was a belief that our economy was stable and wasn't affected by national trends."

She said the focus had shifted from not only what Kansas had done but also what Kansas should be doing.
Carlin and Jack Reardon, mayor of Kansas City, Kan., will discuss factors that affect business locations.
Beryl W. Spinkel, chairman of the President's Council of Economic Advisers, will speak about the national economic outlook and how it will affect the Midwest, Murray said.
