Michael Jackson's former doctor has denied a charge of involuntary manslaughter over the singer's death, at a court in Los Angeles.

在洛杉矶一家法院上，迈克尔·杰克逊的前私人医生否认了过失杀人的指控。

Dr Conrad Murray was bailed² for $75,000 (£48,000) after pleading not guilty（不服罪） to "unlawfully, and without malice³（怨恨，预谋） , killing⁴ Michael Joseph Jackson".

A judge must decide whether to proceed to trial. A conviction（定罪，确信） could bring a jail term of up to four years.

Jackson died at his home on 25 June last year at the age of 50.

His death was ruled as homicide（他杀） , mainly caused by the anaesthetic（麻醉剂，麻药） Propofol.

'Not enough'

A cocktail⁵ of drugs - including sedatives⁷（镇静剂） Midazolam and Diazepam, the painkiller⁸（止痛药） Lidocaine and the stimulant⁹ Ephedrine - were also detected in his body, a coroner confirmed.

Prosecutors¹⁰ had filed one count of involuntary manslaughter（过失杀人罪） .

Dr Murray stood straight and spoke¹¹ softly as he addressed the judge.

After entering his plea, Dr Murray surrendered his passport. He was then taken to have his fingerprints¹² and a mugshot processed.

He is allowed to continue to practice medicine, but cannot use certain drugs.

Judge Keith Schwartz told Dr Murray: "You may not under any circumstances use any anaesthetic agents, specifically Propofol.

"You are not to be using that, you're not to prescribe（开药方，规定） that, you're not to have it in any manner whatsoever¹³（无论什么） ... and you are not to give any other heavy sedative⁶ medications like that."

The bail¹ of $75,000 was three times the standard figure for involuntary manslaughter, but a quarter of the sum prosecutors had been seeking.

The next hearing has been set for 5 April.

Members of Michael Jackson's family - father Joe, mother Katherine, brothers Jermaine, Tito, Jackie and Randy and sister LaToya - were in court for the hearing.

When asked by a reporter as he arrived what he thought about Dr Murray being charged with involuntary manslaughter, Jermaine said simply: "It's not enough".

Joe Jackson said only "looking for justice".
