Japanese Quails were used to evaluate the effects of dietary supplementation with vitamin E (dl-a-tocopheryl-acetate), lycopene, and their combination on egg production, egg quality, concentrations of malondialdehyde (MDA), vitamin E, A and cholesterol in serum and egg yolk. Quails (n = 120; 55 d old) were divided into four groups (n = 30/group) and fed a basal diet or the basal diet supplemented with lycopene (100 mg/kg diet), vitamin E (250 mg dl-慣-tocopheryl-acetate/kg diet) or a combination of lycopene and vitamin E (100 mg/kg lycopene plus 250 mg dl-慣-tocopheryl-acetate/kg diet). Vitamin E and lycopene did not affect (p>0.05) body weight, feed intake or egg weight. Egg production and Haugh unit were greater (p<0.05) in each supplemental group compared with the control group (p<0.05). Serum and liver MDA levels were decreased in supplemented groups compared with the control group. Separately or as a combination, supplemental lycopene and vitamin E increased serum and egg yolk vitamin E and A but decreased cholesterol concentrations (p<0.05). In general, when a significant effect was found for a parameter, the magnitude of the responses to vitamin and lycopene supplements was greatest with the combination of the lycopene and vitamin E, rather than that observed with each supplement separately. Results of the present study indicate that supplementing with a combination of dietary lycopene and vitamin E reduced serum and yolk cholesterol concentrations and improved antioxidant status.

A series of structurally diverse amide derivatives of [6-(3,5-dimethyl-4-chloro-pyrazole-1-yl)- 3(2H)-pyridazinone-2-yl]acetic acid were prepared and tested for their in vivo analgesic and anti-inflammatory activity by using p-benzoquinone-induced writhing test and carrageenaninduced hind paw edema model, respectively. The analgesic and anti-inflammatory activity of the compounds, 7c, 7d and 7k were found to be equipotent to aspirin (as an analgesic) and indometacin (as an anti-inflammatory drug), respectively. The other amide derivatives generally resulted in lower activity on comparision with reference compounds.

The effects of lycopene, genistein, and epigallocatechin-3-gallate (EGCG) on cell viability were tested in vitro using a normal human skin fibroblast (NHSF) cell line (CRL-1474) and granulation tissue fibroblasts (GTFs) obtained from a patient with middle ear cholesteatoma. Cell cultures were added with lycopene (1, 5, and 10 μM), genistein (1, 5, 10, 25, and 50 μM), and EGCG (1, 5, 10, 25, and 50 μM) and their respective control cultures were established by adding 5 mL/L tetrahydrofuran (THF), 5 mL/L dimethyl sulfoxide (DMSO), and 5 mL/L DMSO. A colorimetric assay was employed for determining cell viability using thiazolyl blue tetrazolium bromide. Cell viability was expressed as a percentage of the control. Data were analyzed using two-way analysis of variance separately for each compound. Lycopene addition decreased viability of NHSFs and GTFs compared with THF addition (64.1%, 60.5%, and 100%, respectively, P < .0001). Genistein addition also increased viability of both NHSFs and GTFs compared with DMSO addition (P < .02). Increasing EGCG concentration tended to cause a linear increase in viability of NHSFs but did not alter viability of GTFs (P < .10). Our data suggest that genistein and EGCG but not lycopene could help maintaining or improving skin health through enhancing viability of skin fibroblasts.
