Ca. 5% of the western world show risky alcohol consumption and in some countries such as China a regional yearly increase of alcohol consumption of over 400% has been observed recently （2,3）. The liver is the major target organ of alcohol. According to the recently published ＇Global Burden of Disease Study 2010, liver cirrhosis and liver cancer are ranked at position 12 and 16 in the global deaths statistics （1）. Thus, in 2010, ca. 1 million people died from liver cirrhosis with one third directly attributable to alcohol. This is a considerable number when comparing with coronary heart disease with 7 million deaths and the leading cause of mortality. In central Europe, liver cirrhosis even ranks at the fourth position in YLL. Hepatocellular cancer （HCC） is now the most common fatal complication of patients with alcoholic cirrhosis. Moreover, it shows the second fastest increase of all tumors worldwide after kidney tumors and alcohol-associated HCC ranks on third position after HCCs caused by viral hepatitis B and C.展开更多

The formation of free radicals in the traditional foods induced by ionizing radiation is a part of toxicological studies on irradiated traditional foods was to provide local scientific data base on safe- ty issues.The different foods such as steamed gold fish, spicy curry beef and soy sauces beef were individually vacuum packed in a laminate pouch of PET 12 μm/LDPE 2 μm/AL-Foil 7 μm/LDPE 2 μm/LLDPE 50 μm (PET/Al-Foil/ LLDPE), then kept at frozen state. The frozen samples were maintained in cryogenic condition along the irradiation process by placing the samples in styrofoam boxes filled with dry ice then irradiated with gamma rays at the dose of 45 kGy. The irradiated samples were kept and stored at normal temperature prior to test. Both irradiated conventional rat’s feed at normal temperature with the dose of 4 kGy and unirradiated one as control were also made. Irradiated and unirradiated samples were sent to animal laboratory, and fed into individual female Sprague Dawley rat as member of a group. The parameters observed were body weight changed of rats, toxicological test to observe the effect free radicals formation in rat’s blood by using malon-dialdehyde (MDA) and superoxide dismutase (SOD) methods, respectively, and anatomy pathology diagnosis. Different types of the foods sterilized by ionizing radiation fed ad libitum to the individual Sprague Dawley rat demonstrated that such foods did not give any adverse effect on the reduction of body weight, the toxicological impact, nor anatomy-pathology examinations of the rats.展开更多
