1.1.3 grouping and administration of test animals
Kunming mice (SPF grade), 18-22g in female and male half, purchased from Experimental animals center of pharmaceutical university in Jiangxi.
Taking 70 healthy mice with the weight of 18-22g and half of each sex, randomly dividing the mice into seven groups including a normal control group, a model group, a compound 1, 2 and 3 groups and a single-drug high-dose and low-dose group of Chinese brake herb, wherein each group comprises 10 mice, 5 mice and males, feeding the mice and the males in cages, and marking (distinguishing by left upper/right upper/left lower/right lower/tail/no mark). The normal control group and the model group of mice are filled with 0.1mL/10g of gastric physiological saline, each group of compound pteris multifida is filled with 0.1mL/10g of diluted compound liquid medicine according to 5g/kg, the high-dose group and the low-dose group of ethanol extract of the pteris multifida are filled with 0.1mL/10g of diluted high-dose group and low-dose group respectively, the continuous administration is carried out for 3d, the fasting and the water prohibition are carried out for 2h before and after each administration, the last administration is carried out for 30min, and each group is filled with 0.2 mL/gastric castor oil except the normal control group which is filled with the physiological saline with the same volume.
The mouse was covered under a beaker, and a piece of filter paper was laid under the beaker, followed by observation for 6 hours, with the filter paper being changed every 1 hour. Diarrhea mice were observed for general status and behavioral changes. The mice in each group were observed for changes in mental state, behavior and stool. The data obtained in the test are processed by SPSS17.0 (the data in the first 3h of the report are taken for statistical analysis), and the test of independent samples among groups is carried out, and is expressed as x +/-s.
1.2 Observation index
Taking excrement on each piece or each pile (which means that the number of the excrement can not be separated) on the filter paper as defecation; the dried excrement is not adhered into granules; the loose stool is mostly unformed, has large water content and is internally provided with viscous liquid.
Incidence of diarrhea per hour: the ratio of the number of diarrhea per hour for each group of mice to the total number of mice in the group.
The total diarrhea rate: the ratio of the number of diarrhea in each group of mice to the total number of mice in the group over the observation time.
The rate of loose feces: the ratio of the number of loose stools to the total number of stools per mouse.
A rare excrement stage: the degree of defecation of each mouse was represented by the number of stains formed by the filter paper contaminated with the feces, which was classified into four grades: the diameter < l cm is l grade, 1.0-1.9 cm is 2 grade, 2-3 cm is 3 grade, and >3 cm is 4 grade. The diameter of the stain is measured in a regular circle; the irregular shape is measured by the longest and approximate circle diameter, and the two numbers are added together divided by 2.
Average degree of loose feces: in the statistics, the number of the loose feces in each pile of each mouse is measured one by one, then all the numbers of the loose feces of the mouse are added, and the number of the loose feces is divided by the number of the loose feces, so that the average number of the loose feces of each mouse is obtained, wherein the average number of the loose feces = the sum of the numbers of the loose feces and/or the number of the loose feces.
Sparse feces inhibition = average number of sparse feces per hour for model group-average number of sparse feces per hour for the remaining groups)/average number of sparse feces per hour for model group × 100%
1.3 test results and analysis
Except for a normal control group, after each group of the castor oil is infused with stomach for a period of time, the diarrhea mice show certain diarrhea conditions, and the diarrhea mice show mental depression, lassitude, hypodynamia, coarse hair, secretion around eyes, difficulty in opening, increased defecation frequency, yellowish brown excrement which is not fixed, increased water content of the excrement, viscous liquid in the excrement and less solid content, which shows that the model is successfully established.
The number of loose feces per hour within 0-3 h: except for the normal control group, diarrhea appeared after intragastric castor oil administration. The model group gets worse along with time within 0-3 h, the amount of excrement in the high-dose group and the low-dose group of the phoenix-tail fern is equivalent to that in the model group within 0-1 h, the amount of excrement in the high-dose group and the low-dose group of the phoenix-tail fern is more serious than that in the model group within 1-2 h, but the amount of excrement in the high-dose group and the low-dose group of the phoenix-tail fern is far lower than that in the model group within 2-3 h, which indicates that the antidiarrheal effect time of the single-drug phoenix-tail fern is 2h after the intragastric castor oil is infused; the compound 1 group has no loose feces within 0-2 h of the intragastric castor oil, and the loose feces begins to appear within 2-3 h, but the number of the loose feces is far lower than that of the model group; after the diarrhea starting time of the compound 2 group and the compound 3 group is 1 hour after the castor oil is infused, the quantity of loose stools is obviously reduced compared with that of the model group, and the results show that the compound three groups can obviously delay the time of the first diarrhea of the mice.
Incidence of diarrhea per hour: the incidence rate of diarrhea in the high-dose Chinese brake herb group within 0-3 h is lower than that in the model group, and the incidence rate of diarrhea in the three compound Chinese brake herb groups within 0-3 h is obviously lower than that in the model group (p is less than 0.05);
3h Total diarrhea Rate: the total diarrhea rate of the high-dose group, the low-dose group and the compound three groups of the phoenix-tail fern is reduced by 3h compared with that of the model group, wherein the total diarrhea rate of the model group is 90 percent (9/10), the high-dose group of the phoenix-tail fern is 40 percent (4/10), the compound 1 group and the compound 3 group are 20 percent (2/10) and the compound 2 group is 30 percent (3/10), and thus the incidence rate of diarrhea can be greatly reduced by the three compound groups.
The average stool dilution level of the high-dose group and the compound group of the Chinese brake herb is extremely remarkably reduced by 0-3 h compared with that of a model group (p is less than 0.01); the average stool dilution rate of the three compound groups is obviously different from that of the model group (p is less than 0.05); the inhibition rates of loose stool of the compound 1, 2 and 3 groups are respectively 74.36%, 56.41 and 71.79%. See table 1 for details.

TABLE 1 Effect of Compound Pteris multifida on castor oil induced diarrhea in mice (n =10, ` x. + -. s)
Note: compared to the model group, "a" indicates significant difference (p < 0.05), "a" indicates very significant difference (p < 0.01)
Castor oil is a common drug for replicating a mouse diarrhea model and is commonly used for researching the anti-diarrhea mechanism of traditional Chinese medicines. Castor oil is a stimulant laxative and is a laxative that stimulates the mucous membranes of the small intestine. Castor oil is hydrolyzed into ricinoleic acid by a lipase in the upper part of the small intestine, and intestinal smooth muscle is stimulated by the ricinoleic acid generated by hydrolysis to damage intestinal mucosal cells and cause inflammation, so that intestinal peristalsis is accelerated, absorption of water and electrolytes is inhibited, and exudative diarrhea occurs.
In conclusion, a model test of castor oil induced diarrhea in mice shows that the single-medicine pteris multifida high-dose group and the compound pteris multifida have better antidiarrheal effect, and compared with the single-medicine pteris multifida, the compound three groups have better antidiarrheal effect.
