Nancy Reagan's name is turning into gold for groups trying to raise funds to stamp out drug abuse. Attracted by the first lady's involvement, the Hecht Co. and the J. W. Marriott Corp. are the latest local firms to jump on the bandwagon. Last night, they each gave $30,000 to underwrite expenses of Super Ball '86, the major fund-raising event for Second Genesis Inc., which operates a nonprofit, residential drug and alcohol treatment program in the District, Virginia and Maryland.

Mrs. Reagan, as the ball's honorary chairman, accepted checks from key Marriott and Hecht Co. executives at a VIP reception preceding the $250-a-ticket ball. Representing Marriott was its president and chief executive officer, J. Willard Marriott Jr. Representing Hecht's was President and Chief Executive Officer Irwin Zazulia and Board Chairman J. Warren Harris.

In hopes that other firms might follow suit with similar programs, Hecht's also used the event to announce creation of two fashion internships, in which Second Genesis "graduates" will be hired each year to work in the firm's fashion department.

Put six French chefs together and stand back, especially when three of them almost certainly will be trying to show the other three what gourmet cooking really is. A trio of U.S.-based French chefs will be cooking dinner tonight for a trio of three-star French visitors. It's all part of an evening at the French Embassy to launch "Dining in France," a 13-part series on WETA starting April 26.

The visitors will be Jean-Paul Lacombe of Leon de Lyon, Jean Michel Lorain of La Co te Saint Jacques and Michel Troisgros of Troisgros.

The presiding chefs will be Daniel Boulud of the Plaza-Athene'e in New York (formerly chef here for the head of the European Community); Francis Layrle, chef for the French ambassador, and Jean-Louis Palladin of Jean-Louis at Watergate.

Pierre Salinger, who will be there tonight, hosts the series, which sweeps through France much as Napoleon's army swept through Europe: on its stomach.

"Temperamental" and "confrontational" were two words that Jeane Kirkpatrick says were never used to describe her until she became a public official.

"The truth is that I actually sound much tougher than I am," Kirkpatrick says in the May issue of Ladies' Home Journal. "I'm really kind of a pussycat. I was even that way as a mother. All punishment meant to my kids was being sent to their rooms. I didn't even feel confrontational in the United Nations. I felt maternal. Like when the Syrian endcol ambassador acted up, what I really felt like saying to him was, 'Go to your room!' "

Japanese Prime Minister Yasuhiro Nakasone's invitation to Camp David on Sunday was no casual White House gesture. He's only the third foreign leader to be so honored since President Reagan took office.

The other two were former Mexican president Jose' Lopez Portillo and British Prime Minister Margaret Thatcher. Reagan accorded Mexico that distinction because of his feelings about good neighborliness. As for Thatcher, he's devoted to her, says an American official.

Swedish Ambassador Wilhelm Wachtmeister may be the new dean of the diplomatic corps, but the top dog at the Wachtmeister house is a tiny Lhasa Apso named Chloe.

A mere fluff of a Tibetan temple dog, 3-year-old Chloe jets between the Swedish Embassy here and Christina Wachtmeister's New York digs, where -- like Christina, one of the three Wachtmeister children -- she works as a photographer's model.

Now, Chloe is going international, this time as mascot for the "Just Say No" Clubs headed by TV's Punky Brewster and organized to prevent drug abuse among the elementary school set.

Christina said yesterday it all came about when she volunteered Chloe's services ("I realized that children just go crazy when they see Chloe") by calling upon Nancy Reagan's Projects Director Ken Barun. Barun put her in touch with "Just Say No" and the result is plans for a May 18 Family Day fundraiser at the Swedish Embassy. Cohosting with Chloe and Christina will be Ulla Wachtmeister, Christina's mother.

Invitations, showing Francesco Scavullo's portrait of Chloe on the cover, went out a few days ago. People will have to pay to attend, of course, but well-behaved pets will be admitted free. Christina said Chloe is hoping that Rex Reagan will come.

Said Elaine Crispen, Nancy Reagan's press secretary: "I'll have to check Rex's invitations."

Nancy Reagan hasn't yet said whether she'll be there, but you can be sure that Adolfo's other Washington devote'es won't miss the tribute to him at the Hispanic Designers Fashion Show Sept. 14. He'll be honored at a similar show two nights earlier in Miami.

Last year's show, brainchild of Jane Garcia, wife of the New York congressman, paid tribute to Oscar de la Renta. Next year's will feature Carolina Herrera and will be staged in Los Angeles and Puerto Rico as well as Washington and Miami.

A Miami committee flew here yesterday to meet with its Washington counterparts at the Dominican Republic Embassy. Hosting that session was Luaitieguar Santaella, wife of the ambassador. From there, everybody adjourned for tea to the vice president's House.

Barbara Bush, back from the Middle East, was pressing the flesh when she came across some very familiar flesh, indeed. Nobody had mentioned to her that Columba Bush, her daughter-in-law, was a member of the Miami committee.
