It is well known that saliva contains much amylase, and its secretion is under the control of the parasympathetic nerves.
The present study was undertaken to observe the relationship between amylase activity and the effect of acupuncture anesthesia in order to study the possible role of parasympathetic nervous system in the process of acupuncture anesthesia.
The subjects observed were 105 surgical patients under acupuncture anesthesia (38 cases of total hysterectomy and 67 cases, subtotal gastrectomy).
Specimens of saliva were collected in 2 groups of patients. In group I, saliva was collected by natural flow in the mouth i.e. collection of total amount of saliva in cases for hysterectomy before and after acupuncture induction, and in group II, saliva was collected from the parotid gland duct by using a metal cannula of those patients undergoing subtotal gastrectomy before and after the acupuncture induction as well as during the operation. Salivary amylase activity was then assayed chemically.
Needling for total hysterectomy was carried out at Wushu point penetrating towards Weidao, Qihaishu and Yanglingquan. Needling for subtotal gastrectomy was done at Renzhong, Chengjiang, Xinshu, Neiguan, Pishu and Zusanli points.
The effectiveness of acupuncture anesthesia was divided into 4 grades: excellent, good, fair and poor.
The results showed that, in the case of hysterectomy, the total amylase of those with excellent effect was 25% increase over that before acupuncture. The total amylase of those with good effect was 40% increase. And the total amylase of the patients with poor effect was 78% higher. These rises are significant statistically.
There was a similar response of amylase activity in cases of either subtotal gastrectomy or hysterectomy, but in the patients undergoing subtotal gastrectomy, the response was even more marked.
The increase in the amylase activity of those cases with excellent effect was 1.5 times higher than that before the operation. The amylase activity of patients with good effect was 2 times higher, and the amylase activity of cases with poor effect was 5 times higher than that before the operation.
At the same time the relationship between the change of amylase activity and differentiation of disease according to the traditional Chinese medicine was also observed. According to the symptoms of disease, preoperative responses and the "principle of viscera functions", all the patients were divided into 3 main groups:
1. Those with symptoms of deficiency and coldness of spleen and stomach;
2. Those with symptoms of vital energy of liver attacking the stomach;
3. Those with mixed symptoms of deficiency and sufficiency;
Results of study showed that the amylase activity of cases with group I symptoms and group 3 symptoms was significantly increased after acupuncture induction, but the amylase of cases with group 2 symptoms was practically unchanged.
The above results manifested that the salivary amylase activity increases considerably during the process of acupuncture anesthesia, and acupuncture may regulate the function of parasympathetic nervous system.
