Amniotic fluid

Amniotic fluid - the fluid in the amniotic cavity. The amount of amniotic fluid in norm by the end of pregnancy on average is equal to 1 L. the Amniotic fluid produced by the cells of epithelial amnion and contain proteins, salts, urea, fat, sugar, hormones (the follikulina, gonadotropins, corticoid, progesterone), and the scales of epidermis cells amnion, fluff and lumps Carovigno lubrication. The composition of amniotic fluid in the last months of pregnancy is constantly updated. Amniotic fluid is suitable for the development and movement of the fetus, protect it from external influences, compression of the uterus, play a role in the diet of fruit; during childbirth contribute careful expansion of the cervical canal. Cm. also Childbirth.

Amniotic fluid - the fluid that fills the cavity formed water membrane, which is the germ.
The most widespread opinion of amniotic nature of amniotic fluid is confirmed by the fact that during the operation of education artificial vagina by transplanting fetal membranes allocated amniotic fluid. There is also an opinion that the Acting century produced in amiotroficescom the period trophoblast, in the period of organization of placental circulation - syncytium villi, further - epithelial amnion (Century A. Vikulov).
In the early stages of development eggs amniotic fluid is transparent, in the future, especially towards the end of pregnancy, it becomes turbid due to the ingress of epidermal cells of the fetus, detachable sebaceous glands of his skin, hairs (lanugo) and the availability of different organic and inorganic compounds. Meconium in the amniotic fluid usually appears when asphyxia fruit.
Amniotic fluid contains proteins, sugar, urea, sulphates, phosphates, creatine, mucin, traces of magnesium, cholesterol, soap, enzymes (pepsin, amylase, lipase, hyaluronidase, fibrin-enzyme). From proteins prevail albumin; beta globulins a little, '-globulins are missing. Connective tissue amnion and chorion contains polysaccharides.
In the amniotic fluid, discovered hormones: 1 L. O. C. contains 300 to 470 ME (thinking. units) follikulina, almost the same number of gonadotropins (the number of the last 5-6 month sharply decreases), the number of corticoids and progesterone. The content of vitamins (C, B1, nicotinic acid) depends on the health and nutrition of women. The share of O. century varies 1,002 - 1,028. The freezing point from -0,475 degrees to -0,495 degrees. Their response alkaline or neutral.
In healthy women O. C. usually sterile, which is due to the presence bacteriolytic substance of lysozyme. O. century are complex colloidal-biological environment with diverse effects on the fetus, because of their composition (hormones, vitamins, enzymes, lysozyme and other).
Previously it was thought that the amniotic fluid are only medium that, without hindering development and movements of the fetus, protects it from negative external influences, particularly from the compression of the uterus walls, prevents the adhesion of the fetus with the walls of the ovum, etc. Assumed that the Acting century maintain optimal temperature in amniotic bladder. Currently proven role O. century and in the power of the fetus. Thus, the method of isotopes with subsequent x-rays detected that the person in the last months of pregnancy O. century are in constant motion and renewal. Swallowing O. century, the fetus receives a certain number of bio-elements necessary for its growth and development.
O. century play an important role in the process of childbirth (see). The number of O. C. in the first 5 months. pregnancy is increasing, decreasing in recent months (the time of labour 500-1500 ml). With the formation of a zone of contact predlagay part of the fruit with bone ring of small pelvis amniotic fluid divided into front and rear, forming the fetal bladder, which helps careful expansion of the cervical canal; rear water prevents compression of the umbilical cord and placenta, protecting the uterus from sharp reductions and preventing the violation of placental circulation.
Practically, it is crucial to set the outpouring of the O. C. during pregnancy and childbirth. One of the methods of diagnostics of rupture of membranes is Cytology fresh painted drugs (HP, Saving). On a glass slide put a drop of vaginal secret and cover cover glass. In thin pipette with a small rubber gaining 1% solution eosin, bring an end a pipette to the edge of the glass cover and let a few drops of the solution. Excess colored liquid is sucked off filter paper or lignin, then the preparation is washed with water. Under the microscope on a pink background visible brightly painted epithelial cells of the vaginal walls with nuclei, erythrocytes, leukocytes. When retired waters visible large concentrations unpainted "scales" of the skin of the fruit.
