Abstract: According to an embodiment of the present inventive concept, an electrolyte additive represented by the compounds of Chemical Formulas 1 to 4 may be provided. In addition, according to another embodiment of the present inventive concept, a method for preparing an electrolyte additive of the compounds of Chemical Formulas 1 to 4 may be provided, wherein the method for preparing the electrolyte additive includes reacting hexafluorophosphate and 2-monofluoromalonic acid, further adding an HF scavenger to the mixed solution produced by the reaction, and concentrating and drying the reaction solution obtained therefrom.

Abstract: Provided are a method for administering a recombinant human growth hormone GX-H9 for treating growth hormone deficiency and a pharmaceutical composition containing a recombinant human growth hormone GX-H9 and a pharmaceutically acceptable carrier. The method includes administering recombinant human growth hormone GX-H9 once a week with a dosage of 0.1 to 0.3 mg per weight kg of a patient or twice-monthly with a dosage of 0.1 to 0.4 mg per weight kg of the patient.

Abstract: The present invention relates to a composition for preventing hair loss or promoting hair growth containing a milk thistle flower extract as an active ingredient. More specifically, the present invention relates to a cosmetic composition, pharmaceutical composition and food composition containing a milk thistle flower extract as an active ingredient, which are able to promote hair growth by inducing the proliferation of dermal papilla cells reduced due to senescence, and activate dermal papilla cells by inhibiting the senescence of dermal papilla cells through inhibition of the activity of senescence-associated ?-galactosidase (SA-?-Gal) and the production of senescence-associated secretory phenotypes, thereby preventing hair loss or promoting hair.
