Embodiment 1

[0021] 1.1 Isolation and purification of porcine endometrial cells

[0022] (1) Isolation of endometrial cells (endometrial epithelial cells were isolated by tissue block method)

[0023] Immediately after the slaughter of the pig, the two ends of the uterus were ligated, and the whole uterus was aseptically removed, the fat tissue was peeled off, rinsed with 200 IU double-antibody pre-cooled normal saline solution, placed in the double-antibody-containing normal saline solution, and sent to the hospital as soon as possible. to the laboratory. Clamp both ends of the uterus with hemostatic forceps, take out the uterus in the ultra-clean workbench, soak it in alcohol for about 60 seconds, wash it with PBS after taking it out; cut the uterus longitudinally (close to the uterine horn), wash it 3-4 times with double-antibody PBS, without Bloodstain, cut endometrium to 1 mm 3 Left and right granular, placed in the cell culture plate evenly at intervals of about 0.5 cm, after the t...

Abstract

The invention discloses applications of chitosan-se in inhibiting increase of bax gene expression of swine endometrial epithelium cells caused by F-2 toxin. The experiment result shows that for the endometrial epithelium cells, 0.8-3.0 [mu] mol / L chitosan-se (the final concentration in a culture solution is calculated in terms of se) is used, when the concentration of the F-2 toxin is within the range of 10-30 [mu] g / mL, the increase of bax gene expression of the swine endometrial epithelium cells caused by F-2 toxin can be inhibited, so that the toxic effect of the F-2 toxin for the swine endometrial epithelium cells cultured in vitro can be weakened, and thus an in-vitro study model and theoretical support are provided for the applications of chitosan-se in preventing and treating swinepoisoning caused by the F-2 toxin.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to the application of chitosan selenium in inhibiting the increase of bax gene expression of porcine endometrium epithelial cells caused by F-2 toxin. Background technique [0002] F-2 toxin, also known as zearalenone, is a mycotoxin produced by the genus Fusarium. It is a dihydroxybenzoic acid lactone compound. It has a similar structure to estradiol and has estrogen-like activity. It is widely present in molds. It is one of the main mycotoxins in food and feed contamination. A large number of studies at home and abroad have proved that F-2 toxin has reproductive toxicity, cytotoxicity, liver and kidney toxicity, immunotoxicity and genotoxicity. Long-term feeding of feed contaminated with F-2 toxin will lead to decreased growth performance, low immune function and reproductive dysfunction of livestock and poultry. [0003] Studies have shown that F-2 toxin has an effect on cytotoxic ...
