LONDON, April 1 (Reuters) - European shares rose on Tuesday after UBS <UBSN.VX> unveiled a fresh attempt to reverse its fortunes and writedowns that were along expected lines, sending its shares up 6 percent.
UBS posted $19 billion in additional writedowns and said it was hiving off ailing portions of the bank into a separate unit.
The rally in its shares helped offset a decline in oil and energy shares after crude oil futures <CLc1> fell more than 4 percent since Friday.
Banks were the largest net contributor to the rise in the broader European market, even though Deutsche Bank <DBKGn.DE> surprised investors with a 2.5 billion euro ($3.9 billion) writedown, equivalent to more than a third of its 2007 net profit. Deutsche shares were up 0.1 percent.
By 0844 GMT the FTSEurofirst 300 index <
> of top European shares was up 1.4 percent at 1,279.72 points.In the first three months this year, the index staged its largest quarterly decline since the third quarter of 2002 as fallout from the credit crunch continued and analysts and investors believe the end is not yet in sight.
"It's a bit like stamping on an old toothpaste tube. Every time you think you've used it up, some more creeps out," said Justin Urquhart Stewart, a director at 7 Investment Management.
"Because of the structure of these businesses ... these things only come back to haunt the banks later on, particularly when assets that they're reliant upon are found to be unreliable," he said. "Unfortunately, we've got a whole selection of toothpaste tubes to stamp on before we finally know it's all gone," he added.
The DJ Stoxx index of European banks <.SX7P> was up nearly 2 percent. Barclays <BARC.L> rose 3.7 percent, Credit Suisse <CSGN.VX> gained 4.3 percent and BNP Paribas <BNPP.PA> rose 2.1 percent.
A modest tightening in European credit spreads helped support the broader market. For more please double click on [

FOOD AND DRUGS
Pharmaceutical stocks also rose, led by AstraZeneca <AZN.L> which jumped nearly 5 percent on a JPMorgan upgrade, while GlaxoSmithKline <GSK.L> gained 1.6 percent and Novartis <NOVN.VX> rallied 1.2 percent.
Food producers, led by Unilever <UNc.AS> <ULVR.L>, also ranked among the top positive weights on the market.
Unilever shares were up 2.5 percent, while Nestle <NESN.VX> gained nearly 1 percent and Cadbury Schweppes <CBRY.L> rose 1.4 percent.
Commodity stocks limited the rise in the FTSEurofirst 300 as crude oil fell back towards $100 a barrel and base and precious metals slid in line with a rise in the dollar.
BP <BP.L>, Total <TOTF.PA> and Royal Dutch Shell <RDSa.AS> fell between 0.5 and 1.6 percent, while in the mining sector platinum miner Lonmin <LMI.L> shed 4.2 percent as spot platinum prices <XPT=> dropped, while Anglo American <AAL.L>, Rio Tinto <RIO.L> and Xstrata <XTA.L> lost 3.3 percent.
