Abstract: The present invention is directed to compositions and methods for improving hearing parameters in a human (including hearing volume, hearing range and word recognition) by reversing or inhibiting damage to cochlear cells caused by toxic byproducts of oxygen metabolism. In a preferred embodiment, a pharmaceutically acceptable composition containing insulin-like growth factor one (IGF-1) and human growth hormone (HGH), or their derivatives in a 5:2 ratio by weight, is topically administered every three days in a dosage of 0.1 to 2 mcg per kilogram of body weight. The composition directly penetrates the inner ear and cochlea to provide greater regulation of sodium and potassium levels in the delicate sound-detecting hair cells. In accordance with the present invention, mean word recognition was improved by nearly 39 percent, hearing volume was improved by up to 40 dB, and the hearing range was improved above 6,000 Hz.

Abstract: Methods and compositions are provided for retarding aging, i.e., inhibiting damage to human cells caused by toxic byproducts of oxygen metabolism. The anti-aging active ingredient is a compound or mixture of compounds represented by the following structural formula: ##STR1## wherein m is 0, 1 or 2;n is 0 or 1;R1 is hydrogen, halogen or hydroxy; andR2 and R3 each independently represent hydrogen or methyl provided that when m is 0, n is 0 and when m is 1 or 2, n is 1 and R1 is hydroxy or halogen and that when m is 2, each R2 can be the same or different and each R3 can be the same or different or a pharmaceutically acceptable alkali or alkaline earth metal salt thereof.
