Lactation increases rate of wound healing, lowers stress hormone levels in mice.
2003 DEC 4 - (NewsRx.com & NewsRx.net) -- In a study of mice, scientists found that lactation increased the rate of wound healing and was associated with lower levels of the stress hormone corticosterone when compared with controls.
"Our study was conducted in mice, but may have clinical implications," said study authors A. Courtney DeVries, PhD, and Tara Craft of Ohio State University. "Whether giving birth naturally or via cesarean section, women sustain substantial tissue trauma. Because many of the hormonal changes that occur following birth and during lactation are similar in mice and women, it is possible that lactation (i.e., breast-feeding) may improve healing in women also."
In the study, adult female mice were mated and allowed to give birth. The pups either remained with the mother (postpartum lactation group) or were removed immediately after birth (postpartum non-lactating group). Twenty-four hours after birth, the mothers were given a small superficial skin wound on the scruff of the neck. Wound size was measured daily to determine healing rate.
In a subset of mice, the tissue surrounding the wound was analyzed to provide a profile of immune changes that were occurring in the skin ...
