2. Method of producing a composite material
2.1 Effect on phagocytic function of macrophages in mouse peritoneal cavity
60 mice are divided into 6 groups at random, wherein 5 groups are respectively filled with high, medium and low dose contents of the formula milk powder,
1 time of administration of herba Gynostemmatis total glycoside tablet suspension and commercially available formula milk powder for 10 days; the control group was drenched with equal volume of distilled water.
The experimental mice are killed by intraperitoneal injection of 5% of chicken blood erythrocytes, 0.2ml of each mouse and cervical dislocation after 2 hours, 0.5ml of normal saline is immediately injected into the abdominal cavity, the abdominal cavity is gently kneaded for 2 minutes, then the abdominal skin is cut, a small opening is formed in a muscle layer, the abdominal cavity liquid is taken out and pushed on a clean glass slide, the incubation is carried out for 30 minutes at 37 ℃, microscopic examination is carried out after staining, and direct observation and statistics are carried out under a microscope, so that 2000 macrophages are contained in each mouse.
Phagocytosis rate and phagocytosis index were calculated: the phagocytosis rate F (number of macrophages engulfmg chicken blood erythrocytes/2000) X100%, and the phagocytosis index F (total number of chicken blood erythrocytes engulfed/number of macrophages engulfmg chicken red blood cells).
3. Results
After 10 consecutive days, the above experimental data were statistically processed, specifically by SPSS17.0 software, with the results shown in table 1:
as can be seen from table 1: compared with the control group, the formula milk powder product and the gynostemma total glycoside group of the invention of the embodiment 1 with high, medium and low doses can obviously improve the phagocytosis rate and the phagocytosis index of abdominal macrophages of normal mice, which indicates that the phagocytosis rate of abdominal macrophages of experimental mice on chicken red blood cells can be enhanced, and the cellular immune function of the mice can be improved. Compared with the commercial formula milk powder, the high, medium and low dosages of the gynostemma total glycoside tablet in the embodiment 1 have significant difference (P <0.05 or P < 0.01), and compared with the high and medium dosages of the gynostemma total glycoside tablet in the embodiment 1, the high, medium and low dosages of the gynostemma total glycoside tablet have significant difference (P <0.05 or P < 0.01). This also demonstrates the experimental benefit of the present invention over the prior art.
Verification example 2:
the milk powder disclosed by the invention has influence on the resistance of children, 20 children aged 2.5 years after weaning are selected as group subjects, and the conditions such as height, age and the like of the children are not obviously different from half male to half female.

The experimental group was fed with the milk powder of example 1 of the present invention, the observation group was fed with the commercially available milk powder, supplemented with the normal diet, and observed after 3 months of feeding, and all children were tested for height, weight, CD3+ content, and CD4+/CD8 +.
As a result: the results obtained for the data were all statistically processed using SPSS 17.0. Statistics are carried out by adopting +/-as follows:
as can be seen from table 2, the height of girls was significantly different between the experimental group and the observers, while there was no significant difference between the experimental group and the observers with respect to the height of boys and the weight of boys and girls.
As can be seen from Table 3, the content of CD3+ and the ratio of CD4+/CD8+ were significantly different in the observation group and the experimental group (P < 0.05). Within a certain range, the higher the content of CD3+ (normal range 955-; the ratio of CD4+/CD8+ (normal range is 1.00-2.87) is mainly used for judging clinical diagnosis sensitive indexes of human immune dysfunction.
