Between pragmatism and the defence of a “Sister State” : the national association for the advancement of colored people and the U.S. occupation of Haiti, 1915-1922

À l’origine, la nouvelle concernant l’occupation américaine d’Haïti en 1915 a suscité peu d’indignation aux États-Unis. En effet, on reproche à la république son instabilité politique et on juge aussi qu’une intervention américaine concourrait à l’édifice de l’autorité de la loi. À partir de 1915 et surtout en 1920, l’Association nationale pour l’avancement des gens de couleur (NAACP), fondée en 1909, critique cette ingérence et milite pour y voir un terme. W.E. B. Du Bois et James Weldon Johnson, deux figures publiques noires importantes travaillant au sein de l’organisation, dénoncent avec conviction l’occupation d’Haïti. Les historiens ont jusqu’ici jugé que la NAACP fut inspirée par des considérations de solidarité raciale en adhérant à la cause de la souveraineté haïtienne. Si la thèse présente ne réfute pas cette possibilité, elle cherche tout de même à démontrer que le cadre conceptuel de la solidarité raciale ne saurait illustrer toute la complexité de la campagne haïtienne érigée par la NAACP. Par conséquent, une attention dirigée davantage sur le contexte social et politique américain entre 1915 et 1922 révèle que pour la NAACP, la dénonciation de l’occupation américaine d’Haïti représentait d’une part une opportunité de discuter des problèmes sociaux touchant les Afro-Américains, et d’autre part, une occasion de renforcer sa position aux États-Unis.

Association of reduced extracellular brain ammonia, lactate, and intracranial pressure in pigs with acute liver failure.

We previously demonstrated in pigs with acute liver failure (ALF) that albumin dialysis using the molecular adsorbents recirculating system (MARS) attenuated a rise in intracranial pressure (ICP). This was independent of changes in arterial ammonia, cerebral blood flow and inflammation, allowing alternative hypotheses to be tested. The aims of the present study were to determine whether changes in cerebral extracellular ammonia, lactate, glutamine, glutamate, and energy metabolites were associated with the beneficial effects of MARS on ICP. Three randomized groups [sham, ALF (induced by portacaval anastomosis and hepatic artery ligation), and ALF+MARS] were studied over a 6-hour period with a 4-hour MARS treatment given beginning 2 hours after devascularization. Using cerebral microdialysis, the ALF-induced increase in extracellular brain ammonia, lactate, and glutamate was significantly attenuated in the ALF+MARS group as well as the increases in extracellular lactate/pyruvate and lactate/glucose ratios. The percent change in extracellular brain ammonia correlated with the percent change in ICP (r(2) = 0.511). Increases in brain lactate dehydrogenase activity and mitochondrial complex activity for complex IV were found in ALF compared with those in the sham, which was unaffected by MARS treatment. Brain oxygen consumption did not differ among the study groups. Conclusion: The observation that brain oxygen consumption and mitochondrial complex enzyme activity changed in parallel in both ALF- and MARS-treated animals indicates that the attenuation of increased extracellular brain ammonia (and extracellular brain glutamate) in the MARS-treated animals reduces energy demand and increases supply, resulting in attenuation of increased extracellular brain lactate. The mechanism of how MARS reduces extracellular brain ammonia requires further investigation.
