Granulocyte colony-stimulating factor enhances pulmonary host defenses in normal and ethanol-treated rats.
G-CSF augmented the recruitment of PMNL into the lungs of control rats and significantly attenuated the adverse effects of ethanol on PMNL entry into the lung, and enhanced intrapulmonary bactericidal activity against this pathogen in normal and ethanol-treated rats.

It is concluded that misoprostol is a potent inhibitor of TNF systemic production and inhibits the gastric mucosal injury induced by endotoxemia, suggesting a potentially important therapeutic role for misop frostol in inflammatory diseases in which TNF exerts a contributory role.

Evidence is emerging indicating that alcohol-abusing hosts are seriously undermined by profound disturbances in cytokine production and activity, and the potential to regulate essential functions of the host defense system which may prevent the development and mitigate the severity of infections in these and other immunocompromised hosts is possessed.
Pyruvate alleviates toxic effects of ethanol on cells in culture
The results suggest that drug cytotoxicity testing in vitro must be done using various types of culture medium, because addition of malate to the medium also reduced the cytotoxic effects.

The protective effect of DT827A on a liver injury is due neither to its influence on liver GSH levels nor inhibition of the metabolic activation of CCl4, but a possible mechanism of action for theDT827 series of compounds to indicate an antioxidative effect would be brought about by the role of the compounds as a radical scavenger as well as its reductive effect.
Dharmendra antigen but not integral M. leprae is an efficient inducer of immunostimulant cytokine production by human monocytes, and M. leprae lipids inhibit the cytokine production.

The results suggest that Dh-Ag rather than integral M. leprae may be useful as a vaccine candidate because Dh- Ag is able to induce a large amount of cytokines from monocytes, thus favoring their infection.
