The nutrients of gecko contain a variety of amino acids and trace elements, such as aspartic acid, threonine, glutamic acid, glycine, arginine and so on. It also contains carnosine, choline, carnitine, guanine, protein, fat, inorganic salts and so on. It has the effects of expelling wind and activating collaterals, dispersing stagnation and promoting blood circulation.
Prolonging estrus of female mice can prolong estrus of normal female mice, but it can appear in ovariectomized mice. And make uterus and ovary (normal mice gain the most weight). GEA (Gea) has a direct effect on the gonads (uterus and * * *) of female rats, but its complete effect must pass through ovary, pituitary and hypothalamus. The alcohol extracts from the body and tail of gecko can increase the weight of uterus and ovary of young female mice, and the weight gain effect of gecko tail is stronger than that of gecko body.
Antiasthmatic effect The alcohol extract of Gecko has obvious antiasthmatic effect on asthmatic guinea pigs induced by acetylcholine, and also has direct relaxing effect on isolated trachea of guinea pigs, while the water decoction of Gecko has no obvious effect. However, it has also been reported that the alcohol extract of scorpion has no relaxing effect on guinea pig tracheal smooth muscle induced by histamine or acetylcholine in vitro.
Anti-aging gecko ethanol extract (GEA) can prolong the average life span and semi-lethal time of male and female Drosophila melanogaster, improve the flying vitality and cold tolerance of Drosophila melanogaster, and prolong the survival time of mice under hypoxia. It is preliminarily proved that gecko has certain anti-aging effect.
