RESUMEN

Objective:To study the protective effect of Ophiopogonin D on lipopolysaccharide (LPS)-induced mouse macrophage RAW264.7 and its related mechanism.Methods:Mouse macrophage RAW264.7 cells were cultured and divided into normal control group, model group and Ophiopogonin D pretreatment group according to random number table method. The activity of Ophiopogonin D on RAW264.7 cells was detected by CCK-8 method; the protein levels of TNF-α, IL-1β, IL-6, reactive oxygen species (ROS), MDA and SOD were detected by ELISA; the protein expression of NF-κB, TLR4, NF-E2-related factor2 (Nrf2) and heme oxygenase-1 (HO-1) were detected by Western Blot.Results:Compared with model group, the levels of TNF-α, IL-1β, IL-6, ROS and MDA in cell supernatant of Ophiopogonin D group were decreased ( P<0.05), and the level of SOD was increased ( P<0.05). The protein expressions of NF-κB (0.76±0.10 vs. 2.26±0.17) and TLR4 (0.98±0.09 vs. 1.74±0.19) significantly decreased ( P<0.05). The protein expressions of Nrf2 (0.85±0.03 vs. 0.54±0.03) and HO-1 (0.97±0.11 vs. 0.37±0.04) significantly increased ( P<0.05). Conclusion:Ophiopogonin D may reduce inflammatory response by reducing TLR4/NF-κB pathway, and activate Nrf2/HO-1 pathway to reduce oxidative damage and play a protective role.

RESUMEN

Objective: To investigate the effects of selenium-enriched probiotics on immunity and antioxidation function in mice. Method: One hundred healthy KM mice, female and male in half, were randomly divided into control, sodium selenite, selenium-enriched yeast (Se yeast), selenium-enriched probiotics (Se probiotics) and probiotics groups. One milliliter of water, sodium selenite (2 ?g Se/ml), Se yeast (2 ?g Se/ml), Se probiotics (2 ?g Se/ml) or probiotics were respectively supplemented to five groups in oral (ig) every day. Whole experiment lasted for 28 d. During the experiment, immunity and antioxidation functions were measured respectively. Results: The activation of peritoneal macrophage and thymus index in Se probiotics group were significantly higher than those of other four groups. The spleen index of Se probiotics group was higher than that of control, sodium selenite and probiotics group. The spleen lymphocyte transformation rate in Se probiotics group was significantly or very significantly higher than that in control or probiotics group. In addition, blood GSH-Px and plasma SOD activity in Se probiotics group were significantly higher than those in control and sodium selenite group. Plasma MDA concentration in Se probiotics group was very significantly lower than that in control and sodium selenite group. Conclusion: Selenium-enriched probiotics supplementation could significantly enhance immunity and antioxidation function in mice.

RESUMEN

bjective:To investigate the coefficients of TEOAEs and DPOAEs based on various pass/fail criteria. Method:Thirty-six Australia infants were tested (age range: 1~6 months) using both TEOAE and DPOAE. Cohen′s Kappa (K) were used to analyze different criteria.Result:There is a significant low agreement in the screening outcomes between TEOAEs and DPOAEs, and different criteria for TEOAEs.Conclusion:The findings from the study of coefficients among commonly used screening pass/fail criteria suggested that there is no simple relationship among them. The possible reasons for weak agreement were discussed.

RESUMEN

Objective: To investigate the effects of selenium enriched probiotics on antioxidative activities and immune functions in weanling piglets. Methods: Twenty-four healthy weanling piglets (Duroc?Landrace?Yorkshire ) were divided into 3 groups. One served as control group (C) and two were supplemented different selenium (Se) sources namely selenium enriched probiotics (T1) and Na selenite (T2) as test groups respectively . The experiment lasted for 60 days. The blood GSH-Px activity, blood Se concentration, serum superoxide dismutase (SOD) activity, serum malonaldehyde (MDA) level, serum antibody level of swine fever, and the tissue content of selenium were determined. Results: Blood GSH-Px , Se concentration and serum SOD activity of T1, T2 groups were higher than those of control group after 60 d Se supplementation, and serum MDA content was markedly lower than control group. At the same time, the serum antibody level of swine fever, the tissue content of selenium in T1, T2 group were much higher than control group, and T1 group was higher than T2 group. Conclusion: Organic Se supplementation could significantly enhance immune function and antioxidative activities of weanling piglets.
