RESUMO
Egg yolk immunoglobulin(IgY),also called egg yolk antibody,is a specific antibody secreted by birds after stimulation with certain antigens.For that it exhibits good resistance to heat,acid and proteinase-mediated degradation,its early-stage products were developed as food or food additives,and they have gained great social and economic benefits in both food safety and ecological agriculture fields.Due to the specific antibodies contained in these products,the products can help to resist pathogen infection.Therefore egg yolk antibody shows great value for development and application in the prevention and treat ment of animal and human diseases,and also shows great potential in human health care area.This review focuses on the development and applications of IgY biologics related with antiviral,antibacterial,antiparasitic and antitumor activities.
RESUMO
<p><b>OBJECTIVE</b>To investigate the influence of intensive insulin therapy on the results of postoperative patients with gastric cancer.</p><p><b>METHODS</b>Forty-six patients with gastric cancer underwent radical operation were randomly divided into two groups: intensive group (n=23, to control blood glucose at 4.4 to 6.1 mmol/L) and conventional group (n=23, to control blood glucose at 10.0 to 11.1 mmol/L). Fasting blood glucose( FBG), fasting insulin (FINS), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and C reaction protein (CRP) in 46 patients were detected dynamically during perioperative period. Insulin resistance index (HOMA-IR) were calculated using Homeostasis Model Assessment (HOMA) to evaluate insulin sensitivity. Postoperative complications and other clinical data were recorded.</p><p><b>RESULTS</b>No hypoglycemia occurred in the two groups. Compared with conventional group, morbidity and postoperative duration of fever, antibiotic use and the length of hospital stay in intensive group were significantly reduced (P < 0.05). On the day 1 and 3 after surgery, HOMA-IR and serum levels of TNF-alpha, IL-6 and CRP in patients of intensive group were significantly lower than those in conventional group (P < 0.05).</p><p><b>CONCLUSIONS</b>Intensive insulin therapy could counteract the state of high-inflammation and then improve the outcome of postoperative patients.</p>
