For this reason, the objective of this work was to describe the effect of age and dissociative anesthetics (ketamine and tiletamine), and their combinations with acepromazine, xylazine and zolazepam, on the physiological and blood biochemical parameters in Macaca mulatta. Methods: Eighty male Macaca mulatta were divided into four experimental groups depending on the anesthetic mixture applied. Each group of 20 males was divided into five sub‐groups according to age. Physiological parameters were recorded every five minutes during a 30‐minute period. A blood sample was drawn to analyze blood biochemistry. Results: Statistical analyses revealed significant differences in the physiological parameters between the ketamine‐acepromazine and ketamine‐xylazine groups compared to the control group. The analysis of blood biochemistry found significant differences by age and by anesthetic mixture among all groups. Conclusion: These findings contribute to standardizing this animal model in biological research.展开更多

After artificial aging for 6 min, the vigor was higher than that of the control. The conductivity, malondialdehyde content and soluble polysaccharide content of seed leachate increased with the aging time and negatively correlated ( P 〈 0.05) with the seed vigor indicators. The physiological indicators were very significantly correlated (P 〈 0.01 ) with the vigor indicators in the Medicago ruthenica sample from Dorbod Qi, UIanqab City(China).展开更多

Beck instrument was applied before exams’ period to all students who voluntarily participated and the grades gotten in each of the three Human Physiology exams were correlated with all first year’s averages. Descriptive and inferential statistics were carried out. We found a significant relationship between the complexity of Human Physiology curriculum and the number of cases of depression, resulting in low academic average;high correlations were among Human Physiology contents and those of Biochemistry and Anatomy. It is important to implement support programs to follow students’ emotional welfare as well as to go over the subject’s content.展开更多
