Daily mortality counts

Many time-series studies have addressed the associations between daily mortality counts and pollutant levels, after taking into account weather and temporal trends in mortality. These studies have considered total mortality, exclusive of external causes, and also cause-specific mortality, with focus on cardiac and respiratory causes of death. Total mortality counts are a relatively nonspecific outcome category, because a priori considerations of pathogenesis indicate that effects of particulate air pollution would be anticipated primarily on deaths from chronic cardiac and respiratory conditions and from respiratory infections, inclnd-ing pneumonia and influenza. To date, two studies have linked air pollntion exposure with mortality on a longer time frame (4,5). These stndies are viewed as pivotal because they indicate possible longer-term effects from particnlate polln-... 

Measures of particulate air pollution are associated with daily mortality counts, both for total deaths and for cardiac and respiratory causes. 

In mice orally administered 100 mg/kg of an ethanol extract of cinnamon daily for 90 days, no signs of mortality were observed. Hematological studies indicated a reduction in hemoglobin levels. Increases in reproductive organ weights, sperm motility, and sperm count were observed with no spermatotoxic effects (Shah et al. 1998).
