  • Patent number: 8367060
    Abstract: The present invention relates to a composition and a method for the treatment of liver dysfunction which contains administration of a composition containing arazyme as an active ingredient, more precisely arazyme produced by Aranicola proteolyticus. The arazyme of the present invention inhibits apoptosis in injured liver cells, increases SMP30 expression, inhibits P-smad3 expression and protects the liver by inhibiting liver injury around the central vein region. Therefore, the arazyme of the invention can be effectively used as a composition for the treatment of liver dysfunction.

  • Publication number: 20120003204
    Abstract: The present invention relates to a pharmaceutical composition for the prevention and treatment of cancer comprising arazyme as an active ingredient. More precisely, when arazyme produced by Aranicola proteolycius was administered to the nude mice transplanted with human lung carcinoma cell line, weight gaining, inhibition of tumor cell growth and infiltration, and down-regulations of MMP-9, NF-?B and PCNA, were observed. In addition, when arazyme was treated to human breast cancer cells (MDA-MB-231), down regulations of p21, PCNA (Proliferating Cell Nuclear Antigen), VEGF (Vascular Endothelial Growth Factor), BCl2 (B-cell CLL/lymphoma 2), p-p38, PKC (Protein Kinase C) and MMP-1 (Matrix MetalloProteinase-1) which are involved in tumor cell growth, differentiation, proliferation and metastasis, were observed along with the up-regulation of catalase which inhibits tumor development. Therefore, the arazyme can be effectively used as a pharmaceutical composition for the prevention and treatment of cancer.

  • Publication number: 20110268813
    Abstract: Disclosed is a composition with anti-oxidative, anti-aging and liver-function improvement activities containing ENA actimineral resource A activated water. More specifically, disclosed are a pharmaceutical composition and a health food or health supplement containing, as an active ingredient, an alkaline ENA actimineral resource A activated water prepared from Sepia bone and red algae powders, for preventing aging due to inhibitory activity on decrease in serum vitamin C, or preventing liver damage or improving liver functions due to inhibitory activity on damage, apotosis or necrosis of hepatic cells. The composition inhibits a decrease in in vivo serum vitamin C, to inhibit aging and prevents damage, apotosis or necrosis of hepatic cells, and fundamentally protects liver cells to inhibit damage, apotosis or necrosis of hepatic cells by aging in the liver and improve liver function.
