Singer Ella Fitzgerald, the grande dame of jazz who was hospitalized for treatment of swelling in her foot, was listed in stable condition and "good spirits" yesterday, a hospital spokesman said.

There were initial fears that the swelling in her right foot, a complication of her diabetes, could cut off circulation in her leg and force doctors to amputate, said Ron Wise, spokesman for Cedars-Sinai Medical Center in Los Angeles. But doctors, he said, "are managing the problem in her leg and no surgery is planned."

Ike Turner Pleads Not Guilty

Musician Ike Turner pleaded not guilty Thursday to charges stemming from his latest cocaine arrest.

At his arraignment in Los Angeles, Turner, 55, the ex-husband of Grammy Award-winning singer Tina Turner, pleaded not guilty to charges of transporting cocaine and possessing cocaine. The rock singer and guitarist, who remains free on bail, is scheduled to return to court Oct. 21 for a pretrial hearing.

Turner and codefendant Willie Smith were arrested Aug. 19 after sheriff's deputies stopped Turner's car in West Hollywood and allegedly found nine pieces of rock cocaine weighing about six grams hidden in a dental floss container.

Turner faces separate charges in Pasadena, Calif., Superior Court stemming from a 1985 arrest for conspiracy to sell cocaine.

"We were surprised to see the chimpanzee, but we understand he is {Jackson's} good friend," said a city official. "This is the first time an animal ever entered City Hall."

More than 300,000 people are expected to see Jackson during his 13 concerts in Japan.
