After fetus labour be born, the mammary gland presents lactation period to change.Under a great deal of action of prolactin, PRL that postpartum of in 2~3 days, the breast of parturient, puerpera secrete in the hypophysis, pituitary gland will appear quick bulge big and solid, the parturient, puerpera will feel a bulge pain unbearable.It is lightly and by hand massaging or through suck up of small infant can secrete “colostrum”.Henceforth, along with regulation lactation of establishment, “colostrum” becomes “become mammary ridge”, the breast of the parturient, puerpera meeting regulation ground Chong Ying, row empty, again Chong Ying, again row empty.Breast although because of lactation but become big many, want ?only attention lactation period sanitation and health care, avoid occurrence infection etc. problem, generally will not feel a breast ache unwell, just will feel breast hair bulge before nurse with milk, sometimes the human milk will overflow by oneself, after nurse with milk along with breast of row empty, bulge disappear.The lactation expects breast a series of variety is because of under the prolactin, PRL and other synergetic activities concerning hormone, acinus and intralobular duct obviously increase, intensive, the ceruminous gland palatine canal antrum extends an augmentation, the leaflet organizes obvious decrease, acinus epithelium secret active, parts of epitheliums from sign square mutation pillar form, afterbirth syrup full of discharge, secretion but clearing, nucleosidase circle, Be located on a basilar part;Parts of ceruminous gland antrums highly extend, be full of human milk, the epithelium flat calm;Some discharge, secretion less, eject for the discharge, secretion of performance, after cell regeneration enzyme recovery.It is thus clear that, the secret activity of each acinus isn’t synchronously to carry on, but by turn carry on.In the ablactation count in the days to come, the mammary gland gets in to return to old period variety, acinus rupture, cell collapse, cell endocrine, internal secretion grain disappear, amplification of the catheter diminish or survive, the mesenchyme increase, it is thus clear that spreads in epithelial cell, phagocyte and circular cellular immunity inside the mesenchyme of collapse.Need to last around 3 months to half year, the mammary gland square can recover to the non- pregnancy of condition.Because after epithelium collapse absorb, the hyperplasis of connective tissue can’t completely add a lactation period the mesenchyme of the absorbability and result in after the lactation mammary gland not breast feed so strong, often present to hang to hang a form.If the mammary gland return to old incompletely or anomaly, can appear a lactation to expect hyperplasia of mammary glands or catheter extend etc. pathological changes.
Gestation period and lactation expect the breast to originally possessed of positive or the malignant tumor probably will enlarge, clinical top in response to the ahem.
