The invention belongs to the technical field of biomedicament, and more specifically relates to an application of compound amino acids in preparation of a medicament for improving sensitivity of bacteria to antibiotics. Experiments have shown that a combination of compound amino acids and antibiotics can improve the sensitivity of bacteria to antibiotics, promote an entry of antibiotics into bacterial cells, significantly increase an intracellular antibiotic content, and improve a bactericidal effect of antibiotics, thereby reducing a survival rate of bacteria, and treating diseases caused by bacterial infection.

The present disclosure provides a composition containing a sweet potato stem and/or leaf extract for prevention, alleviation, or treatment of an ear disease. The composition according to the present disclosure can suppress hearing loss by effectively inhibiting the increase in hearing threshold due to hearing loss and the damage to hair cells, and is useful for the prevention or treatment of an ear disease, such as hearing loss or ringing in the ears, by having effects of reducing abnormal behavior caused by ringing in the ears and of returning the hearing amplitude to normal, and therefore, the composition can be advantageously used as a pharmaceutical composition or a health functional food.
