Provided are a neutrophil activation regulator and a therapeutic agent against diseases caused by neutrophil activation. A thrombin-like enzyme is used as an active ingredient of the neutrophil activation regulator and the therapeutic agent against diseases caused by neutrophil activation.

Provided herein is elapidae neurotoxin, and methods for using a pharmaceutically effective amount of said compound to produce synergistic analgesic effect with an opioid for the treatment of pain. In addition, opioid induced hyperalgesia and tolerance can also be alleviated by said compound while administrated separately, or jointly with the opioid.

The present invention relates to improved clotting compositions for producing high quality blood serum samples for analyte testing, such as for pathology testing and other biological assays. In particular, the present invention relates to the use of prothrombin activators in combination with stabilizing agents such as colloids for producing high quality blood serum samples. The present invention also relates to associated methods for preparing clotting compositions, tubes, kits and methods of diagnosis, prognosis and monitoring for responsiveness to therapy.

The present invention relates to pharmaceutical or cosmetic compositions obtained or obtainable from fish hatching fluid comprising polypeptides or portions thereof and the use of said compositions in various medical and cosmetic applications to the skin, particularly for moisturizing skin and/or for exfoliation of the horny layer of the skin for treating or preventing skin disorders or conditions in an animal.

The purpose of the present invention is to provide an agent for improving intestinal flora which can increase the number of beneficial bacteria such as lactic acid bacteria and Bifidobacterium to improve intestinal flora by using an enzyme. A protease consisting of a polypeptide having an amino acid sequence shown in SEQ ID NO: 1 can increase beneficial bacteria such as lactic acid bacteria and Bifidobacterium in intestines to exert an excellent effect of improving intestinal flora.

The present invention relates to a pharmaceutical composition for preventing or treating rheumatoid arthritis, comprising snake venom derived from Agkistrodon piscivorus piscivorus or Naja melanoleuca, which are types of snakes, an extract thereof, or a fraction thereof; a quasi-drug composition; a food composition; a cosmetic composition; and a method of treating rheumatoid arthritis by using the composition. The snake venom derived from Agkistrodon piscivorus piscivorus or Naja melanoleuca of the present invention can improve, alleviate, or treat symptoms of rheumatoid arthritis, which is a kind of autoimmune diseases, and thus will be able to be widely used in the development of therapeutic agents for various autoimmune diseases including rheumatoid arthritis.
