[Efficacy and role of animal placenta]_Benefits_Necessary
The placenta is the body of the fetus during pregnancy. It is completely human. Animals also have placenta. The placenta of animals is also very useful. The placenta contains a lot of nutrients and multivitamins. The placenta of animals can also be used to treat the body.For diseases, it can effectively treat anemia, or physical diseases such as hypertension, and it can also play a good role in preventing diseases.
Effect of animal placenta The animal placenta still has a very good effect on the human body. It has significant effects in treating uterine hypoplasia, uterine atrophy, uterine myositis, uterine bleeding, and milk deficiency. It also has effects on tuberculosis, bronchial bleeding, anemia, etc.Good results, placenta contains high protein.
Because it is a protein, oral administration is not effective and must be injected.
Placenta γ-globulin still contains interferon, which can be used clinically to prevent or control viral infections. The concept of placenta is the combined growth of recombinant embryonic membrane and maternal endometrium during the pregnancy of post mammals and true mammals.Transitional organs that exchange material between mother and child.
Second, classification 1.
According to the shape of the placenta and the distribution of villi, it can be divided into four categories: ⑴ diffuse placenta (dispersed placenta) is relatively primitive and simple, the chorionic sac is a thin film sac; the pits of the inner membrane.
Such as the placenta of whale, fox, monkey, pig, horse, etc .; the cotyledon-type placenta (leaf-shaped placenta) villus is partially concentrated into a leaf-like villous leaf distributed on the chorionic sac.
Such as the placenta of sheep, cow, deer and other anti-judgment animals; ⑶ ring-shaped placenta, the villi are arranged in a ring-shaped band.
Such as elephants, seals, cats, dogs, foxes, and other carnivorous placenta; the placenta-shaped placental villi are concentrated into a pie shape.
Such as carnivorous, pterodactyl, primate, accessory placenta.
The placenta can be divided into two types according to the status of villus contact with the endometrium and the presence or absence of decidua: ⑴ non-decidua placenta, villus extends into the pit of the endometrium, and fingers are inserted into gloves;Pull out from the fossa without harming the endometrium.
Diffuse and cotyledonous placenta fall into this category.
Embryonic decidual placental blastocysts invade the endometrium of the uterine wall and transform deep into the crystals to develop.
The villi are tightly bound to the placental tissue (basal decidua) of the mother’s uterus.
The placenta and decidua of the uterus are excreted together during delivery, with severe bleeding.
Disc-shaped placenta, belt-shaped placenta belongs to this type.
The placenta can also be classified according to the histological distance (how many levels) the material exchange between mother and child: In the most complete structure, maternal nutrients enter the blood through 6 layers of tissue, which are the walls of the mother’s microvessels.Mammalian cell layer, connective tissue layer, endometrial epithelial layer, endometrial proliferative layer, fetal villous core connective tissue layer and microvascular wall endothelial cell layer of blood vessels.
Other animals often disappear in one or more layers.
It can be divided into five categories according to the size of the epithelium: the epithelial chorionic placenta, the chorionic vegetative layer and the endometrium are intact, and the two membranes are close to the placenta. Although there are wrinkles, they are still independent.
Diffuse, non-decidual pigs and horses belong to the placenta.
⑵ Connective chorionic placenta, the endometrial epithelial cell layer is eroded, and the trophoblast is in direct contact with the connective tissue of the uterus.
Such as cattle, sheep and other cotyledon-type placenta.
(3) The chorionic placenta, endometrial epithelial cells and connective tissue of the uterus are all destroyed, and the trophoblast cells of the villi are in contact with the maternal vascular endothelial cells.
Such as cats, dogs and other zonal decidua placenta.
Sinus sinus villus placenta, multiple endometrial epithelium and connective tissue are destroyed, and even the bladder of the uterine blood vessel wall that is in contact with trophoblast cells is eroded, causing blood to flow into the space between the villi; the villi are directly bathed in blood from the motherin.
Such as primates, mice and other discoid decidua placenta.
