RESUMO
Many arteries are responsible for nutrition of brain tissue that one of them is themiddle cerebral artery with its branches [perforating arteries]. The collapse or injury in each ofthese branches lead to brain stroke or pathologic injury in brain so perforating arteries has anatomicimportance and also it is necessary to recognize these arteries therefore we decided to measurelength, outer diameter and number of these vessels in middle cerebral artery.In this descriptive study 26 Brains [21 male and 5 female] of people whowere dead by non brain problems causes were surveyed using usual dissection method. The brainswere taken out in Kerman forensic medical center and dissection of the brains wereperformed inDepartment of anatomy, Kerman faculty of medicine.The length, diameter and number of perforations were measured in middle cerebral artery [MCA].Data were analysed by t-test.Results showed that the main number of perforating artery branches was 6.03 in right and6.57 in left the differences between two parts were not significant. The mean length was 13.61 +/- 0.05in right and 13.72 +/- 0.51 in left that were not significantly different. The mean outer diameter was0.49 +/- 0.01 in right and 0.58 +/- 0.03 in left the difference was significant [p<0.05].This study showedthat the outer diameter of perforating arteries in MCA weresignificantly differentein right and left brain, but the other variables were not significantly differentin right and left brain
RESUMO
Electroconvulsive therapy [ECT] is one of the most effective treatment methods for recovery of the major depressed patients. The most important concerning in the case of ECT is temporary or permanent memory loss. Many patients who have no satisfactory recovery after receiving ECT, claim they have memory dysfunction. The aim of this research was to evaluat memory of the patients hospitalized in psychiatry department of Rafsanjan Moradi teaching hospital before and after receiving ECT in 2003.This analytical study was performed on 50 patients with major depression who received ECT at psychiatry department of Moradi hospital in six months. Memory status of each patient was evaluated by using Wechsler and Babkak memory tests before treatment, 24 hours after each ECT and one week after ending the treatment. The results presented in the form of diagrams and tables and to analyze the data wilcoxon sign rank test and paired t test were used for data analysis.After the first and the second ECTs, 18%-45% and 6%-15% of the patients showed short and long term memory dysfunction respectively. From the second ECT an increased short-term memory was observed, while long-term memory in the third and fourth ECT increased. From the fifth ECT there was no change in patients' memory. Relative frequency of long and short term memory dysfunction in the age group of 45 years old and above, married persons, low educated patients, farmers, house workers; and the patients with previous history of depression was the highest. [p<0.05].This study showed that after treating major depression by using ECT, the patients' memory was improved. However after the first and the second ECTs, some of the patients showed memory dysfunction. It can be concluded that ECT can be used as an effective way for treatment of depressed patients without risk of memory dysfunction
