The aim of this study was to investigate the effect of magnesium sulfate (MgSO4) administered single intraperitoneally on sperm characteristics after testicular ischemia-reperfusion (IR) injury in the male rats.

Thirty adult rats were randomly divided into 5 groups: sham operations (group 1), IR (group 2), IR + 125 mg/kg MgSO4 (group 3), IR + 250 mg/kg MgSO4 (group 4), and IR + 500 mg/kg MgSO4 (group 5). Testicular ischemia was achieved by 720 degrees torsion of the left testis for 2 hours. Then, detorsion was performed and reperfusion was induced. One hour after ischemia, three different doses of MgSO4 (125, 250, and 500 mg/kg) were administrated intraperitoneally. The sperm count, motility, mobility, and blood hematology were evaluated.

There was a significant increase in sperm count, motility, and mobility in groups treated with MgSO4 compared to the sham group (P<0.05). In addition, lymphocyte count in the sham group significantly increased compared to the IR group (P<0.05).

Generally, this study demonstrated that MgSO4 can improve sperm characteristics after testicular IR injury.

diseases are most common diseases in pets, especially dogs. The aim of this study was to evaluate the potency of herbal composition containing green tea extract as a mouthwash on preventing plaque formation and oral diseases in dogs. In order to achieve this goal, 20 male dogs selected and were divided randomly in to two groups including control (Chlorhexidine 0.1%) and treatment (herbal mouthwash) groups. total microbial cunt was performed in swab samples were taken from each dog-oral cavity. In addition, Silness-Loe Plaque Index System was used to evaluate the Improvement of dental plaque and gingivitis.   Percentage of colonies reduction on the last day of the study compared with the first day in control and treatment groups are 84.90% and 73.41%, respectively. In addition, Silness-Loe Plaque Index for control and treatment groups is 0.71 and 0.75, respectively. Results of the present study indicate a favorable effect of herbal mouthwash to prevention and reduce plaque and bacteria in the mouth of pet animals. The herbal mouthwash could reduce the aerobic mouth bacterial load and may prevent plaque formation on teeth and come over halitosis due to infection of the bacteria.
