 or gallbladder diseases. More specifically, liver cirrhosis resulting from alcohol abuse is one of the ten leading causes of death in the United States. Last month the company presented the results of the first studies evaluating the ability of Ceplene to protect against alcohol-induced liver injury in a rat model of alcohol hepatitis. These results suggested that Ceplene provided significant protection against early alcohol-induced liver injury in this animal model.

Yesterday at the DDW conference, Maxim scientists Stephen C. Hornyak, MS and Tapio Haaparanta, Ph.D. presented the results of three studies in which liver injury was induced through the administration of a single dose of ethanol once per day for up to eight weeks in rats. Animals were divided into groups in which some were treated with Ceplene and others were left untreated, while all animals were on a high-fat diet and given ethanol. The animals in the untreated group had significantly higher levels of the liver enzymes ALT and AST (AST Computer, Irvine, CA) A PC manufacturer founded in 1980 by Albert Wong, Safi Quershey and Tom Yuen (A, S and T). It offered a complete line of PCs that sold through its dealer channel. , markers that are elevated when there is damage to the liver. In contrast, animals that were treated with Ceplene showed normalized ALT and AST levels. The animals treated with Ceplene also showed pathology scores for inflammation, necrosis and total pathology that were significantly better (p less than 0.05) when compared to the untreated group.

These results suggest that Ceplene protected against early alcohol-induced liver injury in this animal model. These experiments also demonstrated that there is a dose-dependent effect of Ceplene on protection from liver damage, possibly related to the modulation of certain pro-inflammatory cytokines Cytokines

"Interestingly, the active agent in Ceplene has been shown previously to modulate several key cytokines like TNF-alpha, IL-1b, IL-18 and INF-gamma, and certain of these cytokines have been shown to contribute to the liver damage in ALD," said Dr. Kurt Gehlsen, Senior Vice President and Chief Technical Officer. "Therefore, the protective mechanism of Ceplene may go beyond the established reduction in oxidative stress and may include modulation of key cytokines in the liver."

"The studies reported this week represent the commencement of research to evaluate the potential of Ceplene to be used in the treatment of alcohol-induced liver injury. This research includes ongoing studies to evaluate the ability of Ceplene to accelerate the healing of damaged liver tissue in animal models," added Dr. Gehlsen. "To date we have preliminary data suggesting that Ceplene may accelerate the healing of liver tissue damaged by alcohol and larger studies are underway to establish the healing effect of Ceplene and the role of cytokine Cytokine

Ceplene Overview

 in numerous diseases, is most pronounced in the liver and can damage or destroy liver tissue in patients with hepatitis and other chronic liver diseases.

Ceplene, based on the naturally occurring molecule histamine, has been shown in preclinical work to prevent the production and release of oxygen free radicals, thereby reducing oxidative stress. Accordingly, treatment with Ceplene has the potential to prevent or reverse damage induced by oxidative stress, thereby protecting critical cells and tissues, including the liver.

Such statements are only predictions and the company's actual results may differ materially from those anticipated in these forward-looking statements. Factors that may cause such differences include the risk that products that appeared promising in early research and clinical trials do not demonstrate safety or efficacy in larger-scale clinical trials, the risk that the company will not obtain approval to market its products, and the risk that clinical trials may not commence when planned. These factors and others are more fully discussed in the company's periodic reports and other filings with the Securities and Exchange Commission.
