Description

Endometrium lotion and its application in treating endometritis
Technical Field
The invention relates to the field of animal medicine, in particular to a endometrium washing lotion and application thereof in treating endometritis.
Background
The uterus has been considered sterile for many years. However, since the middle of the 80's in the 20 th century, some studies found that bacteria were present in the uterus after the bacterial culture analysis of endometrial samples, and particularly, in recent years, the research and analysis of endometrial samples by a high throughput sequencing method also revealed that bacteria were present in the endometrium, suggesting possible colonization of bacteria in the uterus. Poor reproductive health outcomes are often associated with colonization of intrauterine bacteria, including chorionitis, pelvic inflammation, endometritis, and the like.
Endometritis is a common obstetrical disease caused by bacterial infection of animals after delivery, is frequently generated in cows, sows, dogs and the like, and has great harm to the reproductive performance of the animals. When the sick livestock suffer from endometritis, factors such as inflammatory products, bacterial toxins and the like act on the uterus, on one hand, normal physiological functions of the endometrium are influenced, and cycle disorder is caused; on the other hand, the vitality of the input sperms is directly influenced, and the implantation of the fertilized eggs and the embryos is blocked, so that the repeated infertility is caused, and some diseases of other reproductive systems can be secondary to cause the lifetime infertility.
At present, methods for treating animal endometritis include uterine perfusion antibiotic, systemic antibiotic therapy, biological method, hormone therapy, Chinese medicinal preparation method, etc., and the commonly used method is uterine perfusion antibiotic or hormone therapy. However, with the application of a large amount of antibacterial drugs, drug-resistant strains are continuously increased, and the application of the antibacterial drugs, hormones and the like is inevitable or drug residues occur, so that harm is indirectly brought to human health. The traditional Chinese medicine preparation has complex prescription, inconvenient operation, large dosage and slow effect; therefore, the problem to be solved urgently is to provide a medicament which has a good effect of treating the animal endometritis, small side effect and low cost.
Disclosure of Invention
The invention aims to solve the problems and provides an endometrial washing lotion and application thereof in treating endometritis.
An endometrial wash, which is a wash obtained by washing the uterus of a healthy animal;
the washing liquid is physiological saline washing liquid;
the healthy animals are unmated sexually mature animals.
The application of the endometrium lotion in preparing the medicine for treating endometritis is disclosed.
The invention provides an endometrium lotion and application thereof in treating endometritis, which is a normal saline lotion obtained by flushing the uterus of healthy animals. The endometritis washing liquid is injected into the uterus with endometritis, and the cure rate of the mouse escherichia coli endometritis model reaches 70%. Clinical tests show that the effective rate of the cow endometritis is 70 percent, and the cure rate is 60 percent.

Detailed Description
EXAMPLE 1 treatment of endometritis mice with physiological saline solution
1. Preparation of physiological saline lotion
Selecting a healthy female virginator mouse (SPF grade ICR mouse) with the age of 8-10 weeks as a healthy donor, injecting 50 mu L of physiological saline into the uterus of the mouse under the aseptic condition, staying for 2 minutes, and then withdrawing 30 mu L of liquid from the uterus to obtain the healthy mouse physiological saline washing liquid. The obtained physiological saline solution was stored at 4 ℃.
2. Clinical trial
1) Animal model
Taking the ICR of SPF grade to be small20 mice, each mouse perfused into uterus to a concentration of 1.0X 101025 mu L of CFU/mL escherichia coli, and after 24 hours, the establishment of a mouse endometritis model is successful.
2) Grouping and administration of drugs
Mice were randomly divided into two groups of 10 mice each, one group served as control group and one group served as treatment group. The treatment group uses the normal saline lotion prepared by the method every day, and uses an indwelling needle to perfuse 25 mu L of healthy bacteria liquid into the uterus, and the control group perfuses 25 mu L of normal saline into the uterus, once a day, and 5 days continuously as a treatment course.
3) Therapeutic effects
The experimental results are shown in fig. 1 and fig. 2, the cure rate of the normal saline control group is 0%, the cure rate of the normal saline lotion treatment group reaches 70%, and the experimental results are significantly different from the control group. The physiological saline lotion has obvious effect of treating the endometritis of the mouse.
EXAMPLE 2 treatment of endometritis in cows with physiological saline solution
1. Laboratory animal
20 sexually mature, unmatched and non-physiological cows with similar ages and body condition characteristics are selected from a certain cow factory in Changchun city, Jilin province and are diagnosed as follows: 1) whether the inflammatory secretion is discharged or not is checked, the inflammatory secretion or the trace (cow tail, nojiri part, and joints with filth and scab) left after the inflammatory secretion is discharged is seen during the check, and the clinical endometritis can be preliminarily determined; 2) rectal examination, which is to examine the position of the uterus, the shape of uterine horn, the size, the texture and the contractile response of the uterus, whether the ovary has a corpus luteum or not and further judge the severity of inflammation; 3) vaginal examination is performed by means of a prolapsus appliance, cervical opening, hyperemia and inflammatory secretion outflow can be seen, the amount and the character of pus are examined, and the nature and the severity of inflammation are determined. The selected 20 cattle have no inflammation symptoms, and the uterus is in a healthy state.
From a certain dairy farm in Changchun city, Jilin province, 40 cows with endometritis were selected and diagnosed as follows: 1) whether the inflammatory secretion is discharged or not is checked, the inflammatory secretion or the trace (cow tail, nojiri part, and joints with filth and scab) left after the inflammatory secretion is discharged is seen during the check, and the clinical endometritis can be preliminarily determined; 2) rectal examination, which is to examine the position of the uterus, the shape of uterine horn, the size, the texture and the contractile response of the uterus, whether the ovary has a corpus luteum or not and further judge the severity of inflammation; 3) vaginal examination is performed by means of a prolapsus appliance, cervical opening, hyperemia and inflammatory secretion outflow can be seen, the amount and the character of pus are examined, and the nature and the severity of inflammation are determined. The uterine horn of 40 dairy cows selected by the test is obviously thickened, the external opening of the cervix is swollen, and all the inflammatory secretion is discharged, and the dairy cows belong to moderate and severe endometritis.
2. Preparation of physiological saline lotion
Selecting the healthy cow as a healthy donor, firstly disinfecting the instruments contacting the cow body and the perineum of the cow by using 0.1% benzalkonium bromide solution, secondly using a rectum to hold semen deposition method, injecting 300mL of sterile normal saline into the uterus of the cow by using a semen deposition device, staying for 2 minutes, and then withdrawing 150mL of liquid from the uterus to obtain the healthy cow normal saline lotion. The physiological saline lotion obtained by 20 selected cows is completely mixed according to the method and stored at 4 ℃ for later use.
3. Grouping and administration of drugs
Grouping: the sick cows were randomly divided into a control group and a treatment group, and each group had 20 cows.
The administration method comprises the following steps: the treatment group was administered 100 mL of the physiological saline solution prepared as described above into uterus daily using a spermatic apparatus. The control group was infused with physiological saline 1 time per day for 5 consecutive days as a treatment course. The treatment results were examined after 1 treatment course.
4. Determination of therapeutic effect
It is divided into curative, improving and ineffective. And (3) curing: clinical symptoms disappear, normal oestrus is recovered, and mucus is normal during oestrus; improving, clinical symptoms disappear, and estrus is recovered, but mucus is abnormal during estrus; no effect, no obvious improvement of clinical symptoms and uterine functions.
5. Therapeutic effects
The treatment results are shown in table 1, the cure rate of the normal saline control group is 0%, the cure rate of the normal saline lotion treatment group is 60%, the effective rate is 70%, and the treatment results are significantly different from the control group.
