“…The addition of antioxidants to the extender has been shown to improve sperm viability of bovine semen (Krzyzosiak et al, 2000;Bilodeau et al, 2002). Vitamins A, C and E have been shown to be potent antioxidants (Breininger et al, 2005;Ondei et al, 2009). The inclusion of fruit juices from orange (Citrus sinensis), cucumber (Cucumis sativus) and pineapple (Ananas comosus) as constituents of semen extenders has recently been proved to improve the quality of stored spermatozoa (Daramola et al, 2016).…”

This study investigated the effects of apple and orange juices on quality of refrigerated spermatozoa of goat bucks. Semen samples from WAD goat bucks were diluted with Tris-egg yolk extenders each supplemented with apple and orange juices at 0, 2.5, 5, 7.5 and 10/100 ml of diluents. The diluted semen samples were assessed for sperm viability and malondialdehyde (MDA) concentration after in vitro storage for 240 hours at 5 o C. The ability to maintain sperm motility was higher in the extenders with 7.5% orange juice followed by 10% apple juice compared to other treatments (P<0.05). The extenders supplemented with 2.5%, 5% and 7.5% apple juice, and 5% orange juice had higher intact acrosome compared to other treatments and the control (P<0.05). The 10% orange juice had higher percentage membrane integrity compared to other treatments. Consistent and reduced (P<0.05) MDA levels were observed in the extenders supplemented with fruit juices and lower MDA was observed in the extenders supplemented with 10% apple juice compared to other treatments and the control (P<0.05). The findings reveal that additions of the fruit juices to semen extenders to maintain the viability of refrigerated spermatozoa were best at concentrations of 10 ml/100 ml of apple juice and 7.5 ml/100 ml of orange juice.

“…Ascorbic acid is a well known non-enzymatic, water soluble natural antioxidant having capacity to reduce MDA concentrations and ROS damage by its chain breaking activity (Ho Lee, 1996;Fanaei et al, 2014). The findings in this present study coupled with better sperm viability parameters suggested that addition of vitamin C as potent antioxidant to semen extenders could reduce deleterious effects of membrane LPO on cryopreserved spermatozoa (Martin et al, 2002;Ondei et al, 2009).…”

“…In vitro studies suggested that the addition of some antioxidants to semen extender could improve motility and survival of spermatozoa (Molinia et al, 1994;Sánchez-Partida et al, 1997;Bilodeau et al, 2002). Vitamin C has been demonstrated as effective antioxidants (Ondei et al, 2009). Perusal of literatures however revealed no information on the effect of supplementation of vitamin C as exogenous antioxidant on sperm viability of WAD buck semen during cryopreservation.…”

Se estudió el efecto de suplementar a los diluyentes con diferentes niveles de vitamina C, sobre la supervivencia de espermatozoides de cabras WAD (West African Dwarf) durante la criopreservación. Para diluir una mezcla de espermatozoides, fueron usados diluyentes basados en tris-yema de huevo, suplementados con 2, 4, 6, y 8 mM de vitamina C. Las muestras de semen, diluidas fueron crioconservadas durante 30 días y a continuación se evaluaron las características de calidad del esperma. Después de la crioconservación, se indujeron in vitro la reacción del acrosoma y la capacitación del espermatozoide. Los resultados mostraron mayor (P

“…Thus, we suppose that alterations of NADH dependent enzymes activity may be also caused by the change in lipid peroxidation intensity [20] This relation is also discussed in other recent works [21] [22]. Thus, accumulation of nicotinamide coenzymes and rise of the second peak of the spectrum, respectively, may also be due to the intensification of lipid peroxidation process.…”

Objectives: Fluorescence spectroscopy which can be used for optical tissue diagnosis of tumor pathology deserves special interest. The purpose of the work was to study blood plasma and tumor tissue of men with different forms of prostate tumors by using laser induced fluorescence. Blood plasma and tumor tissue of the patients with benign hyperplasia of the prostate (BHP), BHP with inflammation, BHP with high grade PIN (BHP with HGPIN) and adenocarcinoma of prostate (CaP) have been studied. Results: In case of blood plasma fluorescence, intensity of the plasma proteins corresponding peak (340-360 nm) was increasing in the following manner: control group → BHP → BHP with HGPIN → CaP. The intensity of the nicotinamide coenzymes correspond peak (440-460 nm) was increased in case of BHP with HGPIN and CaP patients, but decreased in case of BHP, compared to control. In case of tumor tissue, the changes of the collagen peak (390-400 nm) intensity have been revealed in all cases of prostate tumor tissues. These alterations point to altered collagen biosynthesis levels in different tumor tissues, that reflects the structural changes and characteristics of malignant transformation. Also the changes of the nicotinamide coenzymes peak (440-460 nm) intensity in all spectra of tumor tissues were observed. The highest intensity of the peak was observed in the spectra of BHP with HGPIN and in prostate cancer tissue. Conclusions: Alterations of the coenzymes peak intensities perfectly reflect and are in accordance with the specific energy metabolism of prostate epithelial cells. Normalization of fluorescent spectra from different forms of prostate tumor tissues has shown that, each form has typical spectral shape and ratio of fluorescence peaks intensities. L.
