[The effect of pollen in enhancing tolerance to hypoxia and promoting adaptation to highlands].
Mixed pollen containing four sorts of pollens (Rape, Typhae, Corn, Sunflower) has been proved to have many biology effects. It is capable of increasing body tolerance to acute hypoxia and promoting adaptation to highlands. The experimental study showed that pollen can significantly increase body tolerance to acute hypoxia pollen can also increase the high energy content and normalize the activity of several enzymes which are important to high energy metabolism; regulate the neurotransmitter in 4 parts of the brain and maintain normal activities in the nervous system; increase the secretion of adrenocortical hormone which may favour O2 absorption; increase SOD content in tissues (heart, liver) and hence may prevent super-oxygenation and guard against free radicals, increase PO2 in the brain and arterial blood; decrease oxygen consumption and blood lactic acid concentration; and increase the immunity of animals under normal condition. Pollen has neither acute nor chronic toxicity and causes no allergic reaction. In field study, pollen can also reduce and ameliorate symptoms of acute mountain sickness in human beings.
