Effects of avocado seed extract (ASE) in different tris-extenders on sperm and seminal oxidative stress indices of vitrified spermatozoa of West African Dwarf (WAD) goats during vitrification were assessed. Semen samples were diluted with varying levels (0, 5, 10, 15 and 20 mL/100 mL of diluent) of ASE in tris citric acid (TCA), tris sodium phosphate (TSP) and tris sodium citrate (TSC) extenders while a tris-extender without citric acid, sodium phosphate and sodium citrate served as control. Diluted semen samples were vitrified and preserved. The results revealed higher (P<0.05) progressive sperm motility in TCA extenders at 10%, 15% and 20%, and TSP extender at 20% ASE. Acrosome integrities were higher (P<0.05) in the different tris-extenders at 15% and 20% ASE. TCA, TSP and TSC extenders had higher (P<0.05) membrane integrities at 10%, 15% and 20% ASE. TSP extenders had higher (P<0.05) live sperm at 20% ASE. TCA extenders had higher acrosome reaction while TSP at 20% ASE and TSC at 15% and 20% of ASE had higher sperm capacitation. TCA extender at 20% ASE had reduced malondialdehyde (MDA) concentrations while higher acrosin activities were observed at 20% ASE in TCA extender (P<0.05). The findings indicated that 20% ASE in the tris-extenders improved sperm and oxidative stress indices and the tris-extenders were ranked best in this order: TCA > TSP > TSC.

Effects of mucuna seed extract (MSE) in tris-extenders on sperm functional integrities and seminal oxidative stress indices of vitrified sperm of West African Dwarf (WAD) goat bucks were investigated. Varying levels (0, 0.25, 0.5, 0.75, 1 g/100 mL of diluent) of MSE in tris-extenders were diluted with semen specimens. Diluted semen specimens were vitrified and preserved in liquid nitrogen. The results showed that sperm functional integrities (acrosome and membrane integrities) in MSE extenders were comparable. However, seminal oxidative stress indices (malondialdehyde [MDA] and acrosin activity) differed (P<0.05) among the various treatments and the control. The results revealed that semen vitrified with MSE had reduced (P<0.05) MDA concentrations compared to the control. Higher (P<0.05) acrosin activities were recorded in semen vitrified with MSE compared to the control except at 0.25g MSE and optimal values were recorded at 1g MSE. The findings indicated that MSE in the tris-extenders reduced MDA concentration with congruent elevated acrosin activity and consequently maintained sperm functional integrities of vitrified spermatozoa of the WAD goat.

Abstract Background This study aimed to observe the hypoglycemic effect of cassia seed extract in rats with type-2 diabetes mellitus and its effect on reducing insulin resistance in the skeletal muscle. Methods 50 rats were randomly divided into the normal, model, high-dose, middle-dose, and low-dose groups of cassia seed extract (n = 10 each). A high-fat diet combined with streptozotocin administration was adopted to build type 2 diabetes models. The cassia seed extract groups were fed different concentrations cassia seed extract while the normal and model groups were fed the same volume of normal saline. The weight, FINS, GIR, insulin tolerance, blood glucose and blood lipid level, oxidative stress indices and expressions related to the LKB1–AMPK–GLUT4 pathway were detected and compared between the two groups. Results Compared with the normal group, the model group showed lower weight, glucose infusion rate and expressions related to LKB1–AMPK–GLUT4 pathway and higher FINS, insulin tolerance, blood glucose and blood lipid level and oxidative stress indices (all P < 0.05). Compared with the model group, higher weight, glucose infusion rate and expressions related to LKB1–AMPK–GLUT4 pathway and lower FINS, insulin tolerance, blood glucose and blood lipid level and oxidative stress indices were observed in all groups that were administered cassia see extract (all P < 0.05). Conclusion Cassia seed extract could noticeably improve the insulin resistance of diabetic rats and enhance the insulin sensitivity of their skeletal muscles. Its mechanism may be related to damage repair of the LKB1–AMPK–GLUT4 signaling pathway and oxidative stress in the skeletal muscle.

  Objective: This study reports protective effect of Abelmoschus moschatus seed extract against sodium fluoride-induced neurodegeneration through oxidative stress, neurohistological, and behavioral observations in Wistar rats.Methods: A total of 20 Wistar rats (around 250 g) were randomly classified into four groups, namely, control, fluoride (NaF), fluoride + A. moschatus seed aqueous extract (AMAE), and fluoride + A. moschatus seed ethanol extract (AMEE). The control group animals received normal tap water, fluoride group received fluoridated water at the rate of 40 mg/kg b. wt., 3rd group rats treated with fluoride (40 mg/kg b. wt.) + AMAE (300 mg/kg b. wt.), and 4th group rats treated with fluoride (40 mg/kg b. wt.) + AMEE (300 mg/kg b. wt.). Neurobehavioral responses of rotarod, hot plate, and maze learning tests and oxidantive stress markers including lipid peroxidation (LPO), GSH levels, superoxide dismutase, CAT, and GSH peroxidase (GPx) activities, and also histology with H and E as well as congo red staining were studied in control, fluoride, and A. moschatus seed extract treated against fluoride groups.Results: Decreased neurobehavioral responses with rotarod, hot plate, and maze and enhanced LPO (p<0.05) levels were found in fluoride received animals. Whereas, the superoxide dismutase (SOD), CAT, GSH, and GPx were decreased (p<0.05) in NaF treatment. The rats received seed extract along with NaF showed significant reversal of behavioral and oxidative stress markers and the effect of ethanol extract was more pronounced than aqueous extract. The fluoride-treated group showed disturbed cell structure and reduced number of cells in H and E as well as congo red staining which was reversed in cell morphology and restored cell number in seed extract against NaF-treated group. As a result of increased LPO, decreased antioxidant system, and decreased number of cells, neurodegeneration was observed resulting in the disturbance in functions associated with reported behavior.Conclusion: Okra with high antioxidants activity, seed extract showed reversal of LPO levels and antioxidant status in the brain tissue. And also plant extract administered rats displayed normal cell structure and number of cells than only fluoride received group. Therefore, the aqueous and ethanolic extract of A. moschatus plant seeds has neuroprotective effects against fluoride-induced motor, nociceptive, learning behavior, and on histological structure of brain through antioxidant mechanism. The ethanol extract has shown more efficacy than aqueous extract.

Abstract Cadmium (Cd) is an environmental toxic metal implicated in lipid abnormalities. The present study was designed to elucidate the possible association between chronic exposure to Cd concentration and alterations in plasma lipid, lipoprotein, and oxidative stress indices in rats. Sixteen male rats were assigned to 2 groups of 8 rats each (test and control). The Cd-exposed group obtained drinking water containing cadmium chloride (CdCl2) in the concentration of 2.0 mg Cd/L in drinking water for 3 months. At the end of the experimental period, blood samples were obtained to determine the changes of serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), reduced glutathione (GSH), malondialdehyde (MDA) and also serum Cd contents. The results of the present study indicated that Cd administration significantly increased the serum levels of TG, TC, LDL-C, MDA and Cd with reduction in the HDL-C and GSH levels. In conclusion, evidence is presented that chronic exposure to low Cd concentration can adversely affect the lipid and lipoprotein profile via lipid peroxidation.
