Symptoms of a cold

The endotoxins produced by microorganisms are called exopyrogen. When they activate leukocytes, they generate and release endopyrogen such as leucopyrogen, stimulate the anterior hypothalamus, promote the synthesis and release of a large amount of prostaglandin E (PGE), which makes the body temperature set point move up to show aversion to cold and rise of body temperature. As long as the thermogenic factors are not eliminated, the two processes of heat production and heat dissipation continue to balance at this level, and the body temperature will not drop.

Both headache and general pain are caused by endotoxin, and bradykinin is produced. It stimulates nerve terminal receptors to transmit pain along the spinal cord and thalamus to the cerebral cortex. Antipyretic analgesics can relieve pain by interfering with the stimulation of nerve terminal receptors.

Inflammation when tissue mucosa is invaded by microorganisms and viruses and congested, it releases bradykinin, histamine, 5-hydroxytryptamine and other inflammatory mediators and prostaglandins, which dilates local blood vessels and increases exudation. Antipyretic and analgesic drugs obtain antipyretic, analgesic and anti-inflammatory effects by inhibiting the synthesis of PGE.
