During Zheng's tenure, six types of medicine were approved that turned out to be fake and some pharmaceutical companies used false documents to apply for approvals.

In comments on Zheng's case, a spokeswoman for the State Food and Drug Administration, Yan Jiangying, said Tuesday that corrupt officials have shamed the country's food and drug supervision system, Xinhua reported.

"We should seriously reflect and learn from these cases," Yan said. "We should fully protect public food and drug safety. The new drug registration regulation, which will come out soon, will ensure the transparency of the drug approval procedure."

In late June, China shut down 180 food producers that were found to be using improper industrial chemicals and additives.

Also last month, the U.S. Food and Drug Administration said it is imposing stricter controls on farm-raised Chinese seafood because of long-term health concerns about contamination with drugs and unsafe food additives, but that there is no immediate danger to consumers.

The action, which was effective immediately, covers farm-raised shrimp, eel, catfish, and two other kinds of fish, basa and dace, from China, the world's largest producer of farmed fish and the third-largest exporter of seafood to the United States.

The drug varenicline is already on the market under the brand name Chantix to help smokers kick the habit but new preliminary research now suggests it could also be useful in helping heavy drinkers quit.

The research which was carried out on rats provided the rodents with intermittent access to 40 proof alcohol for four months and by varying the access to the liquor supply the rats were made to crave it.

The researchers say every time the rodents had access to booze, they upped their intake and drank all day and withdrawing the alcohol made them want to drink even more.

After months of this behaviour and a total of 37 binge-drinking sessions, all the rats cut their drinking in half when given varenicline.

When taken off the drug, the rats did not immediately imbibe more, a rebound effect that has affected other treatments.

Varenicline has been available as a smoking cessation aid for nearly a year in the U.S. and the European Union, and as well as being safe it does not suppress the appetite and is not metabolized in the liver.

Bartlett says this is a major plus because long term drinkers often have liver damage.

According to the researchers the drug targets a pleasure center in the brain and has the potential to be considered as a treatment for addictions such as gambling and painkillers.

Varenicline works by latching onto the same receptors in the brain that nicotine binds to when inhaled in cigarette smoke, an action that leads to the release of dopamine in the brain's pleasure centers; the drug blocks any inhaled nicotine from reinforcing that effect.

The new study suggests alcohol also acts on the same locations in the brain and varenicline, might be equally as effective for curbing drinking.

Selena Bartlett, a University of California neuroscientist who led the study says the drug has already proven itself safe for people trying to stop smoking and is now a potential drug to fight alcohol dependence.

Experts say smoking and drinking often go together and a single drug able to tackle both addictions is not surprising.

The researchers at the University of California along with the National Institute on Alcohol Abuse and Alcoholism, plan to conduct clinical trials in humans of the drug's effectiveness in curbing alcohol cravings and dependence.

The drug is already approved by Food and Drug Administration and this should speed the process up.

But skeptics warn that varenicline does not work for all smokers and it's highly unlikely it will work for all drinkers and some experts insist there is a common biological basis for addictions to both alcohol and tobacco.

Although drug company Pfizer provided the drug for the study it was not involved in the research and is apparently undecided whether to seek broader FDA approval for the drug.

Pozen Inc. (POZN.O: Quote, Profile, Research), which develops drugs to treat acute and chronic pain, said on Tuesday it has settled a class-action lawsuit filed against the company and its chief executive officer, Dr. John Plachetka.

Pozen said all claims against the company and Plachetka will be dropped without admission of wrongdoing by any party.

The settlement agreement, which remains subject to court approval, will be funded with proceeds from the company's directors and officers' liability insurance.

The latest move in the separation of powers fight between the legislative and executive branches came as members of Congress began returning from their Fourth of July recess. An atmosphere of high tension accompanied the resumption of work as a fight also loomed there between majority Democrats and some key Republicans and Bush over his Iraq war policy.

In his letter regarding subpoenas the Judiciary panels issued, Fielding said, "The president feels compelled to assert executive privilege with respect to the testimony sought from Sara M. Taylor and Harriet E. Miers."

"You may be assured that the president's assertion here comports with prior practices in similar contexts, and that it has been appropriately documented," the letter said.

Fielding was responding to a 10 a.m. EDT deadline set by the Democratic chairmen, Sen. Patrick Leahy of Vermont and Rep. John Conyers of Michigan, for the White House to explain it's privilege claim, prove that the president personally invoked it and provide logs of which documents were being withheld.

As expected, Fielding refused to comply. He said he was acting at Bush's direction, and he complained that the committees had decided to enforce the subpoenas whether or not the White House complied.

"The committees have already prejudged the question, regardless of the production of any privilege log," Fielding wrote. "In such circumstances, we will not be undertaking such a project, even as a further accommodation."

Conyers' response left little doubt where the matter was headed.

"Contrary what the White House may believe, it is the Congress and the courts that will decide whether an invocation of Executive Privilege is valid, not the White House unilaterally," the House chairman said in a statement.

The privilege claim on testimony by former aides won't necessarily prevent them from testifying this week, as scheduled.

Leahy said that Taylor, Bush's former political director, may testify as scheduled before the Senate panel on Wednesday. The House Judiciary Committee scheduled Miers' testimony for Thursday, but it was unclear whether she would appear, according to congressional aides speaking on condition of anonymity because negotiations were under way.

The exchange Monday was the latest step in a slow-motion legal waltz between the White House and lawmakers toward eventual contempt-of-Congress citations. If neither side yielded in that circumstance, it would go to a federal court.

The probe into the U.S. attorney firings was only one of several Democratic-led investigations of the White House and its use of executive power spanning the war in Iraq, Bush's secretive wiretapping program and his commutation last week of I. Lewis "Scooter" Libby's prison sentence.

Meanwhile, several Democratic-run investigations are playing out this week as they head toward contempt of Congress citations and, if neither side yields, federal court.

On Iraq, Democrats expect to resume legislative challenges to Bush's policy on the war as the Senate this week takes up a major defense spending bill. The administration has been concerned about an escalation of Iraqi war fervor. So much so that Defense Secretary Robert Gates canceled a four-nation South American tour this week to work with the White House on Iraq policy. unclear whether she will appear.

Sen. Susan Collins of Maine, ranking Republican on the Homeland Security Committee, said Monday there had been "a steady erosion for the president's policy" in Congress because of the "tremendous loss of life among our troops" in June and "the failure of the Iraqi government to pursue the political reforms that are necessary to quell the sectarian violence."

Collins is among the Senate Republicans seeking to see U.S. troops departing Iraq by early 2008. Bush's strategy for a short-term troop increase to stabilize Baghdad and certain parts of Iraq has not been successful, she said.

"The president argued that we needed to undertake the surge in order to give the Iraq government the time, the space to pursue the political reforms," Collins said on CNN. "That hasn't happened. Instead it has been our troops who are making the sacrifice, who are bearing the burden, and that's why you see a real change in support for the Iraq strategy."

In Baghdad Monday, Iraqi Foreign Minister Hoshyar Zebari warned that a quick American troop withdrawal could lead to civil war and the collapse of the Iraqi state.

China's top court closed loopholes for bribing officials, issuing rules to stem rampant graft that threatens to undermine the Communist Party's grip on power.

The court and top prosecutor jointly issued the rules Sunday in an effort to "catch up with the tricks of wily, corrupt officials," the official Xinhua News Agency reported.

The rules widen the definition of bribery to include money, gifts or favors given to the family members or proxies of officials, or to officials after they retire.

Officials can be charged with graft even if they don't personally get a bribe, and the rules make it illegal to help officials covertly arrange bribes.

The rules come a month after President Hu Jintao stressed again that China must urgently tackle corruption, a deep-rooted problem the party has been battling publicly for a decade.

To fight corruption in the state-controlled media, the government posted on the Internet the names of all Chinese print and television journalists and listed the contact information for their organizations.

Shady dealings by media employees using the names of their newspapers have "marred the reputation of Chinese media," Xinhua reported Sunday, announcing the list.

Chinese reporters often cut deals to write positive stories or suppress negative news in return for bribes or promises to buy advertising in their publications.
