| pubmed-article:1742337 | pubmed:abstractText | Immediately after delivery, lactose was reliably detectable in rat mammary glands (mean concentration 6.49 +/- 0.57 mg/g tissue). The concentrations were not influenced by prepartal biopsy of contralateral mammary tissue. In the morning of the 21st day of gestation (= expected day of labor), lactose was evident in the mammary glands of dams delivering at that day (mean concentration 2.39 +/- 0.17 mg/g tissue). In the tissue of dams delivering on day 22 of gestation, lactose was undetectable. A correlation between prepartal lactose concentration of mammary gland and time remaining up to beginning of delivery (r = -0.96) qualifies this parameter as a rough indicator of term of parturition. | lld:pubmed |
