Background & Objectives : Pain is one of the preceding claims of Parkinson's disease (PD), that its mechanisms have not been fully identified. The purpose of this study was to investigate the chemical pain responses induced by subcutaneous injection of formalin in male parkinsonized rats.
Method : In this experimental study, 40 Wistar male rats were used and PD was established by stereotaxic injection of 6-OHDA toxin into the striatum. Parkinson's disease severity determined by apomorphine-induced rotation test and then the pain response of 4 groups, the control, sham and 2 weak or full Parkinson groups, were evaluated using formalin test. Data were analyzed using ANOVA and Tukey test.
Results : In both acute and chronic phases of the formalin test, the symptoms of pain in different groups were same, but at the interphase stage, pain intensity increased more in Parkinson 's rats, especially in full PD group compared to control (p<0.01).
Conclusion: These results suggest that the nigrostriatal dopaminergic pathway have important modulating role on chronic pain.

Background & objectives: Propolis is a natural product with powerful antioxidant and therapeutic effects. The aim of this study was to investigate the effect of propolis on passive avoidance memory in adult male mice.
Methods: In this study, 40 adult male mice were divided into 8 groups, including control, sham (solvent) and 3 treatment groups orally treated with 50, 100 and 200 mg/kg of propolis, respectively for two weeks before and one week after treatment. Then, passive avoidance learning and memory were recorded in timescales of 24 and 48 hours, 4 days and a week after shock by the shuttle box. Data were analyzed by ANOVA and Dunnett’s post hoc tests, and p<0.05 was considered significant.
Results: Administration of propolis (50 mg/kg) significantly increased the dark chamber entering time at intervals of 24 and 48 hours (p<0.001) and at concentrations of 100 and 200 mg/kg in all time periods after the shock (p<0.001).
Conclusion: Oral administrations of propolis can improve learning and memory dose-dependently in adult male mice.

Background & objectives: Diabetes mellitus cause cognitive defects. Royal Jelly has been claimed to improve the neurological damage caused by diabetes. In this study, the effect of oral administration of royal jelly on memory and passive avoidance learning was studied in diabetic male rats.
Methods: This experimental study was conducted in Qazvin University of Medical Sciences on 48 male Wistar rats. The animals were divided into control, diabetic without treatment, diabetic recipient of glibenclamide (600 μg/kg) and three diabetic groups treated with 50, 100 and 200 mg/kg royal jelly (n=8). Diabetes was induced in the animals by intraperitoneal injection of streptozotocin (60mg/kg/ip). Treatment in the groups performed by gavage from the onset of hyperglycemia for 30 days. At the end of the test, the passive avoidance learning and memory and blood glucose were measured. Data were analyzed by by SPSS software using ANOVA and post-hoc LSD tests, and p<0.05 was considered significant.
Results: Diabetes reduced the latency time of dark room entering. Royal jelly treatment delayed the entrance to the dark room significantly at 24 h, 48 h and 2 weeks after the shock, especially at doses of 100 (p<0.05) and 200 mg/kg (p<0.01) compared to untreated diabetic animals.
Conclusion: According to the results, diabetes causes memory impairment, and royal jelly administration can reduce the memory impairment due to diabetes.

Background & objectives: Electroconvulsive therapy (ECT) is the main therapeutic technique in psychiatric diseases. The use of anesthesia for ECT is necessary. In these patients, selection of anesthesia with minimal hemodynamic changes is very important. The aim of this study was to compare the hemodynamic effects of two anesthetics including sodium thiopental and propofol in patients undergoing ECT.
Methods: This study was performed on 84 patients (50 males and 34 females) who were anesthetized for ECT in 22- Bahaman Hospital, Qazvin University of Medical Sciences (QUMS). Initially, the hemodynamic status of patients was recorded. Then, they randomly received either sodium thiopental or propofol as an anesthetic and succinylcholine as a muscle relaxant. Hemodynamic changes, including systolic and diastolic blood pressure, pulse rate in the 1, 3 and 10 minutes after ECT, as well as seizure duration and recovery time were recorded. The data were analyzed by SPSS v.20 using independent t-test.
Results: the sodium thiopental group, showed the highest changes in systolic and diastolic blood pressure and heart rate in the third minute (45%, 64% and 26% respectively). In the propofol group, the highest systolic, diastolic and mean arterial blood pressure changes were 55%, 64% and 43% respectively, at the 10th minute, but the highest pulse rate (33%) occurred in the 3rd minute. The blood pressure changes were significant between the two groups (p<0.05). The post-shock seizure duration was less with sodium thiopental, but recovery from anesthesia was shorter with propofol (p<0.05).
Conclusion: Our findings showed that in the anesthetic required for electroshock, sodium thiopental had a slightly better hemodynamic stability than propofol. Therefore, it seems appropriate to use it as an anesthetic for ECT.
