Does cCK1-receptor stimulation protect against gut mediator-induced lung damage during endotoxemia?
During endotoxemia enteral LCFA absorption reduces TNFα release into mesenteric lymph and attenuates histomorphologic parameters of lung dysfunction. Failure to elicit this effect in CCK1R(-/-) mice demonstrates that anti-inflammatory properties of LCFAs are mediated through CCK1-Rs.
These results demonstrate that acute ethanol administration impairs spatial working memory and that such a deficit is not contingent on a learning impairment. These results support earlier findings that acute ethanol administration impairs spatial working memory but provide a significant advance by validating a novel training procedure that allows for direct investigation of working memory. Ethanol's impairment of both spatial working memory and spatial reference memory strengthens the similarities between memory impairments due to ethanol administration and memory impairments due to hippocampal lesions.
