Pharmaceutical compositions containing a synergistic combination of at least one antifungal active ingredient and at least one keratolytic agent and methods of treating tinea pedis with the pharmaceutical compositions are described. These pharmaceutical compositions include synergistic combinations of naftifine or terbinafine and urea, or naftifine or terbinafine and ammonium lactate, for effective treatment of moccasin-type and interdigital-type tinea pedis.

The present invention relates to a pharmaceutical composition for the prevention or treatment of hearing loss containing ammonium lactate as an active ingredient. It has been confirmed that treating hair cells damaged by gentamicin with ammonium lactate increases the number of normal hair cells, and therefore, a pharmaceutical composition containing ammonium lactate as an active ingredient can be used to prevent or treat hearing loss, a side effect of using the antibiotic ammonium lactate.

This invention relates to the field of material modification technology, and discloses a method for modifying activated carbon fiber cloth using a composite hydrothermal method and its application. The method includes: immersing the activated carbon fiber cloth in a mixed solution of lactic acid and ammonium salt at a mass ratio of 1:(0.8-1.2), subjecting it to a water bath heating and shaking reaction at 70-90℃, and then removing the activated carbon fiber cloth for cleaning and drying. This method allows lactic acid and ammonium salt to simultaneously undergo acid oxidation modification, ammonium salt nitrogen modification, hydrothermal modification, and other composite modifications on the carbon structure of the ACF surface under a water bath shaking environment. Furthermore, the ammonium salt-lactic acid mixed solution can form a buffer solution system, ensuring the stability of the ACF water bath reaction environment. Through the above composite modification, a certain degree of etching can be produced on the ACF surface, increasing the specific surface area of ​​the carbon fibers and the number of active contact sites; acid oxidation modification can increase the number of oxygen-containing functional groups on the carbon fiber surface; and nitrogen modification by ammonium salt can increase the number of nitrogen-containing functional groups on the carbon fiber surface.
