1.  Aloe vera Aqueous Extract Effect on Morphine Withdrawal Syndrome in Morphine-Dependent Female Rats 
Aloe vera is a medicinal herb used as an anti-inflammatory and sedative agent.
The current study aimed to evaluate the effect of Aloe vera aqueous extract on morphine withdrawal symptoms in morphine-dependent female rats.
Patients and Methods:
The current research was performed on 40 female Wista-Albino rats which were made dependent on morphine using Houshyar protocol and were randomly divided into five groups (A, B, C, D, and E). Group A did not receive any agent in the period of handling but other groups (B, C, D and E) received 5, 10, 20 and 40 mg/kg of Aloe vera aqueous extract by gavage, three times daily for a week, respectively. Withdrawal symptoms, stool form, agitation, disparity, floppy eyelids, and body mass variations were checked for 10 days. The obtained data were analyzed using SPSS v.11 software, and Friedman, Kruskal-Wallis, and Mann-Whitney statistical tests. Statistical difference was considered significant (P < 0.05).
The results of the present study showed that agitation, disparity, and floppy eyelids in group E were significantly higher than those of others groups; however, these symptoms in group C were significantly lower than those of the other groups.
The results of the present study revealed that the Aloe vera aqueous extract had various effects on morphine withdrawal syndrome in morphine-dependent female rats .

2.  Arterial blood pressure in female students before, during and after exercise 
ARYA Atherosclerosis  2012;8(1):12-15.
Physical activity (PA) has been associated with reduced blood pressure in observational epidemiologic studies and individual clinical trials. Since PA is considered as a key component for the prevention and treatment of hypertension in children and adolescents, the purpose of this study was to assess blood pressure changes in athletic and non-athletic students before, during and after PA.
The subjects in this experimental study consisted of 60 female athletic (n = 30) and non-athletic students (n = 30) with an average age of 21-23 years. The athletes were physical education students and non-athletes were medical students. Blood pressure (BP) at the right arm was measured in sitting position at 5 minutes before, 6 minutes after starting PA and 5 minutes after the end of the exercise. Weight, height, body mass index (BMI), mean arterial pressure (MAP) and pulse pressure (PP) were measured by ordinary methods. Data was analyzed using student's t- test. Results were expressed as mean ┬▒ SD. The statistical difference was considered significant at P < 0.05.
The results showed that while systolic BP (SBP) increased during and 5 minutes after the end of physical exercise in both groups, diastolic BP (DBP) decreased. However, SBP values were significantly lower in non-athletic female students compared to the athletes. On the other hand, DBP values were significantly lower in athletic female students compared to non-athletes. Moreover, heart rate values were significantly lower at rest, during and 5 minutes after the end of physical exercise in athlete female students compared to non-athletes.
Our results revealed that physical activity reduced arterial BP levels in female athlete students.
