Lower BMD and BMC in EtOH-fed rats were associated with decreased bone formation in the proximal tibia, increased proportion of adipocytes, and increased expression of TNF-\u03b1. EtOH-induced skeletal deficits were prevented by treatment with either NAC or sTNFR1. These data suggest that postlactational anabolic rebuilding is influenced by EtOH consumption and may affect the long-term risk of osteopenia.<\/jats:p>\n                  <jats:p>Introduction: Despite significant loss of bone during lactation, BMD is restored by a powerful anabolic rebuilding process after weaning. A significant number of women resume alcohol consumption after weaning their offspring from breast feeding. The objectives of this study were to examine the consequences of chronic ethanol (EtOH) consumption on the postlactational rebuilding process and to investigate the underlying mechanisms by which EtOH mediates its detrimental effects.<\/jats:p>\n                  <jats:p>Materials and Methods: Female Sprague-Dawley rats (n = 7\u20139 per group) were fed EtOH-containing diets (13 g\/kg\/d) for 1, 2, or 4 wk after weaning of their offspring. Skeletal parameters in the proximal tibia were examined using pQCT, \u03bcCT, and histomorphometric techniques, and interventional studies were performed on the mechanistic roles of EtOH-induced oxidative stress and TNF-\u03b1.<\/jats:p>\n                  <jats:p>Results and Conclusions: EtOH consumption completely abolished the anabolic bone rebuilding that occurred after lactation. Decreased BMD and BMC were associated with decreased bone formation and not with increased osteoclast activity. Furthermore, EtOH-fed rats showed greater proportion of fat volume\/bone volume and expression of adipocyte-specific genes. EtOH-induced skeletal effects were mitigated by the dietary antioxidant, N-acetyl cysteine or by blocking TNF-\u03b1 signaling. These data suggest EtOH consumption in the period immediately postweaning may significantly impair the mother's skeletal health and lead to long-term osteopenia.<\/jats:p>","DOI":"10.1359\/jbmr.071023","type":"journal-article","created":{"date-parts":[[2007,10,29]],"date-time":"2007-10-29T14:00:47Z","timestamp":1193666447000},"page":"338-349","source":"Crossref","is-referenced-by-count":33,"title":["Chronic
