Therefore, it can be effectively used for diagnosing and/or treating an infectious disease.

Abstract: The present disclosure relates to a method for determining the mortality risk of an infectious inflammatory disease on the basis of the concentrations of tryptophanyl-tRNA synthetase (WARS) and cytokines. The method for determining the mortality risk of the present disclosure can effectively identify patients who are at high risk of mortality due to an infectious inflammatory disease within a short period of time and, as such, can be very helpful for performing timely therapy.

Abstract: The present invention relates to Aralia extracts and a therapeutic agent comprising Aralia extracts as an active ingredient. The composition and therapeutic agent according to the present invention are effective in preventing cataract, delaying the development of cataract, and treating cataract. According to the present invention, extracts of Aralia are obtained by extraction with alcohol. Addition of myo-inositol or taurine to the extracts will result in a synergistic effect in the treatment of cataract. In addition, oral administration of beverages, galenicals, and nutraceuticals, which comprise Aralia extracts as an active ingredient, will be effective in prevention, delay and treatment of cataract caused by complications of diabetes. Aralia extracts will have the same effect in the case where they are used as an ophthalmic agent. They can also be used as an eye drop or an eye ointment.
