This study evaluated effects of vacuum-infused fresh chicken breast meats with grape seed extracts, green tea extracts, or tertiary butyl hydroquinone on pH, texture, color, and thiobarbituric reactive substances after cooking using a microwave or conventional electric oven for 12 d storage at 5 degrees C. Thiobarbituric reactive substances values of uncooked (raw) chicken breast meats for 0 to 12 d of storage ranged from 1.12 to 3.5 mg of malonaldehyde/100 g of chicken. During 0 to 12 d of storage, thiobarbituric reactive substances values ranged from 2.50 to 7.80 and from 2.4 to 7.35 mg of malonaldehyde/100 g of chicken breast meat cooked by microwave and conventional electric oven, respectively. Meats cooked by microwave had higher redness and lower lightness values than those cooked by conventional electric oven. Also, meats cooked by microwave had higher maximum shear force, working of shear, hardness, springiness, cohesiveness, and chewiness values than meats cooked by conventional electric oven. Tertiary butyl hydroquinone was the most effective in raw and cooked meats in reducing lipid oxidation, followed by grape seed and green tea extracts. Plant extracts are effective in preventing undesirable changes in chemical properties in chicken breast meat caused by microwave and conventional electric oven cooking.

To evaluate the prevalence of hepatitis C virus infection in our hemodialysis population, we carried out a survey of 273 adult hemodialysis patients in three hemodialysis units in Jordan using a second generation rapid enzyme immunoassay. Sixty seven patients were seropositive with a prevalence of 24.5%. All patients were transfusion dependent except two. More than 85% of the patients have been on hemodialysis for more than two years. Co-infection with hepatitis B virus was observed in six patients. Abnormal liver functions were seen in five patients, but liver biopsies were not done. The prevalence of hepatitis C antibody in healthy blood donors in Jordan is 1.7%. We conclude that HCV infection prevalence in hemodialysis patients in Jordan is 24.5%, a percentage similar to what has been reported around the world and in the neighboring countries.
