Embodiment 1
[0045] A method for extracting small molecule sheep placenta, carried out according to the following steps:
[0046] (1) Choose healthy, 2-3-year-old multiparous ewes with normal estrus cycle as the sheep to be pregnant. All the sheep have been treated with quarantine, epidemic prevention and medicinal baths, and the feed is supplemented with green fodder, vitamins and trace amounts. element;
[0047] (2) Intramuscularly inject cloprostenol at 7-14 days of the luteal phase of the expectant sheep, and start to observe estrus 30 hours later. When estrus is observed, artificial semen collection and insemination are performed 12 hours after estrus, and can be compounded once every 24 days after estrus. After 35 days, a B-ultrasound examination was performed to confirm the pregnancy status;
[0048] (3) When the fetal sheep grows to 85-100 days, the fetal sheep is taken out by operation, placed in a high-temperature sterilized container, washed with sterile saline, and the eyeball...
Embodiment 2
[0062] (1) The ewes were dissected by surgical methods to obtain sterile fetal sheep, which were placed in sterile containers, washed with normal saline, and eyeballs, brain, liver, lungs, heart, intestines and stomach were removed.
[0063] (2) Rinse with sterile saline, drain and weigh.
[0064] (3) Add sterile pure water and fragments of fetal sheep to homogenate, add pure water to dilute the homogenate, the quality of pure water is 3 times that of fetal sheep, and the homogenate dilution is filtered through a three-layer stainless steel filter screen, and the upper layer is 20 Mesh, the middle layer is 50 mesh, and the lower layer is 100 mesh.
[0065] (4) The homogenized filtrate is placed in a sterile container and placed in a -30°C refrigerator, frozen overnight, or stored.
[0066] (5) The frozen homogenate filtrate was taken out and thawed at room temperature, transferred to a sterile heat-resistant container, placed in a 70°C water bath, and kept at 70°C for 30 minu...
