Background

Dry eye is also called keratoconjunctival xerosis, which is a general term for various diseases caused by abnormal quality or quantity of tear fluid or abnormal dynamics due to any reasons, resulting in the reduction of the stability of tear film and accompanied by ocular discomfort and/or pathological features of ocular surface tissues. Common symptoms include dry eyes, easy tiredness, itching eyes, foreign body sensation, burning sensation, viscous secretion, aversion to wind, photophobia and sensitivity to external stimulation; sometimes, the eyes are too dry, the basic tears are insufficient, and the reflex tears are stimulated to secrete, so that the frequent tears are caused; in more severe cases, the eyes become inflamed, engorged, keratinized, and the corneal epithelium is broken and the filaments are adhered, and this damage may cause keratoconjunctival disorders and affect vision over time. Recent studies have suggested that changes in the ocular surface, immune-based inflammatory responses, apoptosis, changes in sex hormone levels, etc., are factors involved in the development of dry eye.

Experimental example 3 evaluation of curative effect of salvianolic acid A eye drops for treating rabbit xerophthalmia caused by local atropine dripping

The method of using 1% atropine sulfate for local dripping is adopted to induce a rabbit dry eye model, and normal saline is used as a contrast, and the treatment and improvement effects of the 0.05% salvianolic acid A eye drops prepared by the method in the embodiment 2 of the invention on the rabbit dry eye model eye are observed. 20 common-grade New Zealand rabbits (40 eyes) are respectively female and male, 1% atropine sulfate eye drops are dropped into both eyes, 1% atropine sulfate eye drops are dropped into the eyes at 8, 12, 16 and 20 days, respectively, and 1-2 drops are dropped each time to induce rabbit dry eye model eyes. Randomly selecting 10 rabbits, treating with 0.05% salvianolic acid A eye drop, 3 times per day, 2 drops per time, and continuously using for 14 days as experimental group; the control group was prepared by using normal saline 2 times a day, 2 drops each time, for 10 additional rabbits. The animals in the experimental group and the control group are administered with 2.5 g.L per day in both eyes^-1The eye drop containing chloramphenicol can be used for anti-infective treatment 1 time per day, 2 drops per time, and continuously for 14 days. The results of the study are as followsThe following:

1. after the animals in the eye observation and treatment group are given the salvianolic acid A eye drops, the symptoms of congestion and edema of the eyes of the experimental group are relieved compared with the model eyes in the control group, and the animals with conjunctival secretion in the rabbit eyes of the experimental group have fewer animals and the degree is relieved.

2. Compared with the cornea fluorescein staining score before the atropine is dripped for molding, the cornea fluorescein staining score of each observation time point after the control group is dripped with the atropine is obviously increased (P is less than 0.01) compared with the cornea fluorescein staining score before the dripping with the atropine; the time points after the dropping of the medicine in the experimental group have no statistical difference (P is more than 0.05) compared with the time points before the dropping of the medicine. Compared with the control group, the experimental group is obviously lower than the control group (P is less than 0.01) at other observation time points except for the 14 th day before and after the dropping. See table 8.

TABLE 8 fluorescein staining scores (n-10) before and after molding and after dropping of the drug for the experimental and control groups

Note: p < 0.05, P < 0.01, compared to the composition before molding; compared with the control group, the delta P is less than 0.01.

The Schirmer test showed a significant reduction (P < 0.01) in the Schirmer I test values at time points after the control group was dosed compared to the control group before the dosing. The time points after the dropping of the medicine in the experimental group have no statistical difference (P is more than 0.05) compared with the time points before the dropping of the medicine. Compared with the control group, the experimental group is obviously higher than the control group (P is less than 0.01) at other observation time points except for the 1 st and 14 th days before and after the dropping.

TABLE 9 changes in the wet length of the filter paper from the Schirmer I test before and after administration of salvianolic acid A ophthalmic solutions (n ═ 10)

Experimental results show that the salvianolic acid A eye drops have a certain curative effect on the treatment of the rabbit xerophthalmia of the atropine dripped locally, can inhibit the appearance of the rabbit xerophthalmia induced by the atropine eye drops, promote the secretion of the tears of the rabbits, obviously increase the secretion amount, and are expected to become a novel ophthalmic preparation applied to clinic.

The other products of the invention were tested in the same way and the same results were obtained, which are not listed any more depending on the space.
