Abstract--Effects of Sodium and Potassium in diet to determine rats baby have been investigated.20 healthy rats chosen from the first generation of the previous experimented rats ,were divided into two groups in the ratio male to female 1:5. The first group was Na and K, the second group was control unit without Na and K. It was found that the delivered offspring male to female ratio were 2.61:1 and 1.02:1 for the first and second groups respectively. Also, it was found that rats fed with (Na, K) food yields maximum numbers of male offspring 68, while rats fed with normal food yields lowest numbers of male offspring 48.
Objective: Humans always have faced with the phenomenon of anxiety and have tried to find solutions to overcome this problem by various methods. The aim of this study was to determine the effect of echium amoenum on the anxiety of college students. Methods: This is a clinical trial study. Participants were 40 nursing students in Kerman, Iran who were randomly assigned into two groups of intervention (n=20) and control (n=20). The data collection tools were a demographic form and Cattle’s anxiety questionnaire. First, the baseline assessment was conducted in both groups. Then, the intervention group received 1 g echium amoenum powder in 250cc boiling water daily. After a month, both groups were assessed again. Data analysis was performed in SPSS v.20 software using descriptive and inferential statistics (mean, standard deviation, chi-square test, paired t-test, independent t-test, Mann-Witney U test). Results: At baseline, there was no significant difference between the two groups. After consumption of echium amoenum, the overall anxiety score decreased from 40.4±6.31 to 38.65±3.39 in the intervention group and increased from 39.7±9.29 to 41.75±9.91 in the control group; however, these differences were not statistically significant. Conclusion: Echium amoenum could reduce anxiety in the students, but its effect was not significant maybe due to the short duration of its use or small sample size. Hence, further studies with a larger sample size are recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
