the IL-6 detection result is shown in figure 6B, and it can be seen from the figure that there is no significant difference (no statistical difference) in the expression of the inflammatory factor IL-6 among the three groups of the gastrodia elata-olive oil combined experimental group, the olive oil experimental group and the normal saline group, but compared with the gastrodia elata-olive oil, the gastrodia elata up-regulates the expression of the inflammatory factor IL-6 in the liver of a mouse, and the experimental result shows that the gastrodia elata-olive oil can reduce the risk of related diseases caused by induction of the gastrodia elata and the inflammatory factor IL-6 in the liver, and reduce the toxic and side effects of the gastrodia elata on the liver.
Example 6 detection of IL-1 β and TGF- β inflammatory factor expression in mouse Kidney
1. Mouse kidney sample preparation method refer to example 5, step 1;
2. the detection method is the same as the step 5 of the embodiment 4;
the detection results are shown in fig. 7A, and it can be seen from the figure that the gastrodia elata experimental group and the olive oil experimental group can both up-regulate the expression of IL-1 β in the kidney of the mouse compared with the gastrodia elata-olive oil combined experimental group, and the experimental results show that the gastrodia elata-olive oil can reduce the risk of related diseases caused by the induction of inflammatory factors IL-1 β in the kidney when the gastrodia elata and the olive oil are used alone, and reduce the toxic and side effects of the gastrodia elata or the olive oil on the kidney when the gastrodia elata or the olive oil;
RT-qPCR upstream primer 5'-GTGTGGAGCAACATGTGGAACTCTA-3' and downstream primer 5'-TTGGTTCAGCCACTGCCGTA-3' of TGF- β, RT-qPCR product size 238 bp of TGF- β, and detection results are shown in figure 7B, and it can be seen from the figure that a gastrodia elata experimental group and an olive oil experimental group can both up-regulate TGF- β expression in mouse kidney compared with a gastrodia elata-olive oil combined experimental group, and the experimental results show that the gastrodia elata-olive oil can reduce the risk of related diseases caused by inflammatory factor TGF- β in kidney when the gastrodia elata and the olive oil are used alone, and reduce the toxic and side effects of the gastrodia elata or the olive oil on kidney when the gastrodia elata or the olive oil are used alone.
