Title: Novel Bioactive Protein Isolated From Chinese Yam and Uses Thereof
Usefulness: Novel Bioactive Protein Isolated From Chinese Yam and Uses Thereof
Summary: The bio active peptide is used in composition and medicine for achieving therapeutic effect chosen from increasing serum level of estradiol, estrogen, and/or progesterone, treating osteoporosis and menopausal syndrome in a subject, preferably human at menopause, perimenopause or postmenopause period having menopausal syndrome and osteoporosis, and improving cognitive function and stimulating a splenic mitosis response (all claimed) and chitanase activity and modulating immunity in a subject e.g. female apes, humans, dogs, cats and chickens. The peptide is used in the form of e.g. ingestible tablets, buccal tablets, capsules, elixirs, suspensions, syrups or wafers.
Novelty: New bio active peptide e.g. isolated or substantially pure polypeptide, fragment of polypeptide and variant having sequence identity with polypeptide, used for e.g. increasing serum level of estradiol, estrogen, and/or progesterone
