[0020] The preparation method of the compound preparation for improving the immune function of the body by way of exception in this embodiment: After crushing the above-mentioned Chinese medicine components through a 20-mesh sieve, mixing, and decocting 3 times with water for 30 minutes each time, the amount of water is the total amount of the Chinese medicine components. 10 times the amount, combine the water extracts, concentrate the water extracts at 60°C under reduced pressure to obtain the Chinese medicine compound extract, crush it, and pass through an 80 mesh sieve to obtain the fine powder of the effective part extract of the Chinese medicine compound preparation; take the tragacanth gum 1.2 g Place in a dry mortar, disperse with proper amount of ethanol, add 1.0ml of polysorbate 80, add about 25ml of distilled water at a time and grind well, add 50g of cod liver oil to grind into colostrum: take 5g of fine powder of Chinese medicine compound extract and sodium benzoate Disperse 0.02g in about 5ml of distilled water, add it to the colostrum and mix it evenly, add 20ml of distilled water and stir it evenly. After dispensing, prepare the nose drops.

[0021] The present invention conducts mouse experiments to verify the therapeutic effect of the compound preparation for improving the immune function of the body.

[0022] 1. Equipment.

[0023] 1.1 Animals: Kunming mice, 18-22g, male and female, all clean grade, provided by the Experimental Animal Center of Shenyang Pharmaceutical University.

[0024] 1.2 Instruments: electronic balance, microplate reader, stopwatch, capillary glass tube (inner diameter 1mm, length 10mm).

[0025] 1.3 Medicine: physiological saline, ginseng decoction 0.2g·ml -1 (Calculated by converting the amount of crude drug, self-made), the compound powder (powder) of the effective part of traditional Chinese medicine that can improve the immune function of the body in this Example 1 (hereinafter referred to as LAH).

[0026] 2. Method.

[0027] 2.1 Mice swimming experiment: Take 48 Kunming mice of half male and female, and randomly divide them into normal saline group, ginseng group, LAH low-dose group, LAH high-dose group, 12 in each group. The normal saline group was given 0.3ml of normal saline a day, and the ginseng group was given 1g·kg of ginseng decoction -1 ,; LAH low-dose group was given LAH nasal drops 1.2g·kg -1; LAH high-dose group was given LAH nasal drops 5.3g·kg -1; All the above groups were administered by nasal instillation for 7 consecutive days. One hour after the last administration, load the tail of the mouse (5% of body weight) and swim in a glass tank with a water depth of 20cm and a water temperature of (20±0.5) ℃. Record the mouse from entering the water to sinking to the bottom and unable to swim out of the water. time. All test data are expressed as mean±standard deviation, and the swimming time of mice is tested.

[0028] 2.2 Experimental hypoxia tolerance in mice: 48 Kunming mice with half male and half females were taken, and the grouping and administration were the same as in item 2.1 above. One hour after the last administration, the mice were put into a 250ml wide-mouth bottle, stuffed into the bottle cap, sealed with petroleum jelly, airtight, and timed immediately, using respiratory arrest as an indicator to observe and record the survival time of the mice. All test data are expressed as mean±standard deviation, and survival time test is performed.

[0029] Table 1: The effect of LAH on normal mice's swimming time and normal pressure hypoxia tolerance time.

[0030] Group Dose C/g·kg -1 Mouse swimming time t/min Survival time t/min Normal saline - 14.56±3.27 20.68±4.21 Ginseng 1 16.24±5.13 ** 23.15±3.05 ** LAH low dose 1.2 15.01±4.98 * 21.79±5.15 * LAH high dose 5.3 16.84±3.46 ** 23.58±4.26 **

[0031] It can be seen from Table 1 that high-dose LAH has a significant effect on the swimming time and oxygen-consuming survival time of mice. The swimming time and survival time of mice are significantly better than the low-dose LAH group and the saline group, and the high LAH The swimming time and survival time of mice in the dose group were similar to those in the ginseng group. Therefore, the externally applied compound preparation of the present invention has a certain positive effect on the body's anti-fatigue, and effectively reduces the production cost on the basis of ensuring the curative effect.

[0032] 2.3. Randomly split, recombine, increase or decrease the flavor and amount of the thirty-four traditional Chinese medicine components in the compound preparation of Example 1, to form 6 groups of formulas, and repeat mice swimming with the saline group and the ginseng group Experiment and hypoxia tolerance experiment, the experimental results are shown in Table 2.

[0038] Formulation 6 (34 flavored medicines): The raw material components and dosages of traditional Chinese medicines and the preparation method are the same as in Example 1.

[0039] 2.3.1 Ninety-six Kunming mice of half male and female were randomly divided into physiological saline group, ginseng group, combination 1, combination 2, combination 3, combination 4, combination 5, and combination 6, with 12 mice in each group. The normal saline group was given 0.3ml of normal saline a day, and the ginseng group was given 1g·kg of ginseng decoction -1 , (All are calculated as crude drugs, self-made); Combination 1 is given to formula 1 nasal drops 5.5g·kg -1; Combination 2 gives the nasal drops made by formula 2 4.2g·kg -1; Combination 3 gives nasal drops made by formula 3 5.7g·kg -1; Combination 4 gives formula 4 nasal drops 4.4g·kg -1; Combination 5 gives formula 5 nasal drops 5.1g·kg -1; Combination 6 gives formula 6 nasal drops 5.3g·kg -1; All the above groups were administered by nasal instillation for 7 consecutive days. One hour after the last administration, load the tail of the mouse (5% of body weight) and swim in a glass tank with a water depth of 20cm and a water temperature of (20±0.5) ℃. Record the mouse from entering the water to sinking to the bottom and unable to swim out of the water. time. All test data are expressed as mean±standard deviation, and the swimming time of mice is tested.

[0040] 2.3.2 Experimental hypoxia tolerance in mice: 96 Kunming mice with half males and half females were taken, and the grouping and administration were the same as those in 2.3.1 above. One hour after the last administration, the mice were put into a 250ml wide-mouth bottle, stuffed into the bottle cap, sealed with petroleum jelly, airtight, and timed immediately, using respiratory arrest as an indicator to observe and record the survival time of the mice. All test data are expressed as mean±standard deviation, and survival time test is performed.

[0041] Table 2: The effects of different amounts of medicines on mice swimming time and normal pressure hypoxia tolerance time.

[0042] Group Dose C/g·kg -1 Mouse swimming time t/min Survival time t/min Normal saline - 14.56±3.27 20.68±4.21 Ginseng 1 16.24±5.13 ** 23.15±3.05 ** Combination 1 5.5 14.82±5.02 * 20.79±5.11 * Combination 2 4.2 14.98±4.72 * 20.93±4.94 * Combination 3 5.7 15.03±3.56 ** 21.61±4.52 ** Combination 4 4.4 14.47±3.26 ** 20.84±4.05 ** Combination 5 5.1 15.21±3.98 ** 22.55±3.89 ** Combination 6 5.3 16.84±3.46 ** 23.58±4.26 **

[0043] It can be seen from Table 2 that different amounts of medicines and compatibility principles have significant effects on the swimming time and oxygen-consuming survival time of mice. Among them, the swimming time and oxygen-consuming survival time of mice in combination 6 are significantly better than other formulas. In the group, the swimming time and oxygen-consuming survival time of mice in the "Jun, Chen, Zuo, Shi" prescriptions with more complete medicinal flavors were better than those of mice with incomplete "Jun, Chen, Zuo, Shi" medicinal recipes Swimming time and oxygen consumption survival time. It can be seen that the compatibility principle of "jun, minister, adjuvant, and messenger" of the compound preparation for external use to improve the immune function of the body of the present invention is a reasonable choice after optimization.
