“…Therefore, these sites regard to be the main sites of ROS production in frozen semen. EL has antioxidant activity (Panjaitan et al, 2013;Varghese et al, 2013;Khanam et al, 2015) and Superoxide Dismutase (SOD) activity (Tambi and Imran, 2010) that can reduce the amount of ROS and protect cell membranes from the deleterious effect of ROS in frozen-thawed semen. Moreover, EL has about 70 bioactive components (Kuo et al, 2004;Bhat and Karim, 2010;Meng et al, 2014) and also EL is well Known as energy provider (Bhat and Karim, 2010;George and Henkel, 2014) which may contribute to protect and promote sperm survival and motility by providing energy.…”

“…Traditionally it is used to treat fever, malaria, erectile dysfunction (Bhat and Karim, 2010). EL has been well described to be anti-oxidant (Varghese et al, 2013), anti-tumour (Al-Salahi et al, 2014Tong et al, 2015), anti-inflammatory (Han et al, 2016), anti-malarial (Kuo et al, 2004), anti-microbial (Khanam et al, 2015), anti-parasite (Kavitha et al, 2012) and anti-stress (Talbott et al, 2013). It has also been reported to improve sex derive of the male (Ang and Sim, 1997;Low et al, 2013;Ebrahimi et al, 2016) and female (Abdulghani et al, 2012).…”

This study was carried out to improve the kinetic motilities of frozen-thawed bull semen diluted with tris-based egg yolk diluent that was supplemented with Eurycoma longifolia jack aqueous extract. A total of 24 ejaculates were obtained from six cross-bred bulls using an electro-ejaculator. The extract of Eurycoma longifolia jack was distributed into three low doses and three high doses; cryopreserved samples were evaluated into three different times to confirm the results of kinetic motilities through different times and between groups. Path velocity (VAP µm/s), progress velocity (VSL µm/s), track speed (VCL µm/s), lateral amplitude (ALH µm/s), Beat Frequency (BCF Hz), straightness (STR %), linearity (LIN %), were evaluated three different times using Computer-assisted sperm analysis. Results revealed that the percentage of VAP, ASL and VCL were higher (p<0.05) in the frozen-thawed semen group supplemented with 5 mg mL .54 in third evaluation; respectively). In conclusion, Eurycoma longifolia Jack aqueous extract supplementation to the semen diluent at 5 mg mL −1 significantly improved sperm kinetic motilities of frozen-thawed bull semen.

“…All gram-positive bacteria were susceptible, while the gram-negative bacterium (E. coli) was not susceptible, which may be associated with the power of extract to penetrate inside bacteria. The membrane of gram-negative bacteria is highly hydrophilic and acts as a barrier against external agents such as hydrophilic dyes, antibiotics and detergents (6,26). As a result, the permeability of the membrane of these bacteria is much less than that of gram-…”

Background and Objective: Nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. Medicinal plants are also of great importance as antibacterial agents. Therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of nettle (Urtica dioica L.) leaves using two methods of disk diffusion and well diffusion.Methods: Ethanolic extract of nettle leaves was prepared by the percolation method. Effect of different concentrations of the extract on Escherichia coli (PTCC1399), Staphylococcus aureus (PTCC 1431), Staphylococcus epidermidis (PTCC 1435) and Staphylococcus saprophyticus (PTCC1440) was evaluated using the disk diffusion and well diffusion methods by measuring diameter of growth inhibition zone. Gentamicin and propylene glycol were used as positive and negative control, respectively.Results: In both methods, especially in the well diffusion, the ethanolic extract of nettle leaves had favorable inhibitory effect on the growth of S. aureus, S. epidermidis and S. saprophyticus. In the well diffusion method, the highest rate of susceptibility to the extract (89%) was related to S. saprophyticus and S. epidermidis. Conclusion:The ethanolic extract of nettle leaf has good inhibitory effect on the growth of S. aureus (especially in the well diffusion method), which confirms the traditional use of this plant for the treatment of urinary tract infections.

“…Phenolic compounds are aromatic secondary metabolites that impart color, flavor and associated with health benefits such as reduced risk of heart and cardiovascular diseases. Phenolic compounds account for most of the antioxidant activities in plants [14]. Phenolics are compounds possessing one or more aromatic rings with one or more hydroxyl groups.…”
