Application example 1
Study of the efficacy of the Chinese medicinal composition for treating headache obtained in example 1
The method comprises the steps of establishing a chronic migraine animal model by injecting nitroglycerin into the abdominal cavity of a mouse at a low dose for many times, recording the frequency of the front limb of the mouse, detecting biochemical indexes of Nitric Oxide (NO), dopamine (DA), calcitonin Gene Related Peptide (CGRP) and 5-hydroxytryptamine (5-HT) of the mouse, and carrying out pharmacodynamics experimental study on the composition for treating migraine.
The nitroglycerin can enhance the excitability of ash neurons around the tail of the trigeminal nerve and the midbrain aqueduct, improve the afferent reaction of the spinal cord dorsal horn to the nociceptive information, further lead the afferent branch of the trigeminal nerve which innervates the meninges to generate delayed and long-acting pain sensitization, and reduce the threshold value of pain sensation. The nitroglycerin is one of the donor substances of NO, can stimulate the organism to promote vascular smooth muscle to release NO to cause intracranial and extracranial vascular dilation so as to produce headache, and simultaneously, the NO activates guanylate cyclase through dispersion action, so that vascular smooth muscle is promoted to relax, and the intracranial and extracranial vascular dilation is caused to cause headache. In addition, NO can mediate the release of various neuropeptides such as calcitonin gene-related peptide, trigger neurogenic inflammation, and participate in migraine attacks. Administration can be by subcutaneous injection, intravenous injection, and intraperitoneal injection, with intraperitoneal injection being the most common. The acute and chronic migraine of the people can be simulated by adjusting the quantity of single injection. NO, DA, CGRP and 5-HT are important biochemical indicators for the detection of migraine. NO has neurotoxic effects that trigger trigeminal-vascular reflex, inducing experimental migraine. 5-HT is an important neurotransmitter in migraine attacks, one of the total essential neuroactive substances in the central endogenous analgesic system, and increased release during migraine attacks can cause endorphin release in the pituitary to participate in pain regulation, associated with central nervous system pain transmission and endogenous analgesic mechanisms; DA is a neurotransmitter next to 5-HT in migraine attacks, and is also released to increase during migraine attacks, closely related to migraine attacks; CGRP is the predominant neuropeptide associated with the trigeminal system and has a strong vasodilating effect, causing headaches by vasodilating, and plays an important role in migraine attacks. The effect of the composition on treating headache is studied by detecting biochemical indexes such as NO, DA, CGRP, 5-HT and the like in mouse serum.

SPF grade ICR mice were purchased from Liaoning long biotechnology Co., ltd in 60, male and female halves, body weight (18.+ -.2) g. Mice were fed habitually for 1 week, with free water and food prior to the experiment.
2. Experimental grouping
The experimental mice were randomly divided into 5 groups, control, model, high, medium, and low dose groups of 12 animals each. The high, medium and low dosage groups (high dosage 1.44g/kg, medium dosage 0.72g/kg, low dosage 0.36 g/kg) are respectively administered with the Chinese medicinal composition with different concentrations, and the physiological saline group (i.e. control group) and model group are administered with the same volume of physiological saline, and the stomach is continuously irrigated for 7d.
3. Model building
After 60min from the last administration, 5mg/kg of nitroglycerin injection was injected intraperitoneally into each experimental group 1 time every other day for 9 days in succession for 5 total injections. The control group was injected with the same volume of distilled water, resulting in an experimental migraine model. The administration was continued during the molding.
4. Observation of the number of times of mouse's scratching
After the last intraperitoneal injection of nitroglycerin for 30min, the number of times of scratching the forelimbs of each of the experimental group and the control group mice in 30min was recorded by a counter, and the results were recorded.
5. Biochemical index determination
After the end of the scratching test, blood was collected from the orbital veins of the mice in each of the administration group and the control group, and the blood was centrifuged at 3000 rpm for 10 minutes, the serum was separated, the NO content in the serum was measured by the nitrate reductase method, and the DA, CGRP, 5-HT content in the serum was measured by the ELISA method.
6. Experimental results
6.1 times of mouse scratching
Note that: * p < 0.05
6.2 Biochemical index determination
The level of each biochemical index in the dosing group was significantly reduced compared to the model group. There were significant differences in 5-HT levels in the lower dosing group compared to the model group; the levels of NO, 5-HT in the medium dose group were significantly different; there were significant differences in both high dose groups NO, DA, CGRP, 5-HT.
Note that: * p < 0.05
7. Conclusion(s)
According to the observation of the frequency of the mouse's head and the measurement of biochemical indexes (NO, DA, CGRP, 5-HT), the traditional Chinese medicine composition can correct the level abnormality of monoamine neurotransmitters in migraine attack by down-regulating the levels of NO, CGRP, 5-HT and DA in serum, so that the release and metabolic mechanism of the monoamine neurotransmitters in the organism can be restored, and the neurotransmitters can be combined with corresponding receptors or target sites to improve the brain dysfunction, improve vasomotor dysfunction and effectively prevent migraine induced by nitroglycerin.
