Relationship between Submaxillary Secretion and Blood Flow in the Cat
|

Abstract
|
|
|
In urethane-anesthetized cats, arterial blood pressure, submaxillary secretion and blood flow in response to chorda stimulation, cervical sympathetic stimulation and various drugs were observed; the relationships between the secretion and blood flow, and between the secretion and blood pressure were investigated. The results obtained were as follows:
1. Chorda stimulation elicited copious salivary secretion and increased the blood flow through the gland, but did not affect the blood pressure.
2. Intravenous injection of acetylcholine or pilocarpine elicited salivary secretion and increased the blood flow, but decreased the blood pressure.
3. Intravenous injection of ATP increased submaxillary blood flow and decreased the blood pressure, but did not evoke the secretion.
4. Intravenous injection of vasopressin increased the blood pressure but did not elicit the secretion.
These results suggest that the salivary secretion is accompanied by increased glandular blood flow, however, increased blood flow is not always associated with secretion; and that the salivary secretion is not related to arterial blood pressure.
