Soror Arman

Introduction: Sexual instinct which is the cause of numerous changes in one’s life could be influenced by numerous factors such as menopause and aging. This study was focused on comparison of women’s sexual functioning disorders before and after menopause. Materials and Methods: This is an analytic cross sectional study in which data related to before and after menopause sexual activities of 174 married women (living with their spouses), referring to health centers in Isfahan in 2003 was collected and investigated. Data was collected by a self constructed sexual dysfunction inventory in which reliability and validity were reached by content validity and α chorenbach index. Findings were analysed through descriptive and inferential (MC-Nemar) statistics. Results: Findings showed that relative frequency of sexual functioning disorders in productive period was 38% and in menopausal period 72.4%. There was a significant association between sexual functioning disorders before and after menopausal period (P < 0.001). Frequency distribution of sexual functioning disorders in productive period of these women according to severity of disorders were: sexual desire disorder (49/2%), dyspareunia (34/3%), arousal dysfunction (26/8%), orgasmic dysfunction (23/8%), and vaginismus (16/4%). Frequency distribution of sexual functioning disorders in menopausal period of these women were: arousal dysfunction(75/3%), sexual disire disorder (62/6%), orgasmic dysfunction (56/3%), dyspareunia (34/9%) and vaginismus (15/8%).
Conclusion: As revealed by the findings of the study,a high percentage of women experience sexual functioning disorders in productive and menopausal periods. Menopause can be a cause to occur, or continue these disorders. The role of health care professinals in conselling and education is emphasized.

The Effect of Intrahippocampal Injection of Verapamil on Pentylenetetrazol Kindling in Rats

Mohamadreza Palizvan

Introduction: Studies showed that following spontaneous epilepsy in rats, the permeability of CA1 region of Hypocampus to calcium is increased. In this study the role of voltage dependent calcium channels on the development of kindling induced by Pentylenetetrazol (PTZ) was investigated in rats.
Materials and Methods: In this experimental study rats were divided into two groups. In the test group, Verapamil (calcium channel blocker) was injected in the Hippocampus (4 g/4 min). After 20 minutes kindling was established by PTZ in subconvulsive dose (37.5 mg/kg ip). Convulsing activities were monitored for 20 min. The control group was the same age and undergone the same procedure exept for the injection, in which ACSF was injected without Verapamil.
Results: Verapamil significantly (p<0.01) reduced the number of needed stimulations to progress from stage 0 to 5 of the convulsion and also significantly (p<0.05) prolonged the fifth stage of seizure.
Conclusion: The results of this study suggested that interahippcampal injection of Verapamil facilitated the Pentylenetetrazol kindling in rats but had inhibitory effects on kindled animals.

Mahmood Rafieian

Introduction: Different groups of drugs are used for prevention of migraine headaches. Howevere, there are controversy about the afficacy of these drugs. Furtheremore, the priority of one to other group is not clear. This study was designed therefore, to compare the effects of Propranolol and Nimodipine on sevierity, duration and frequency of migraine headache.
Materials and Methods: In a clinical trial study, 102 patients with migraine headache refered to neurology clinic were chosen. Patients were devided into two drug groups. Group one received 40 mg Propranolol per day and group two received 30 mg Nimodipine. Data was collected by a questionnaire. Patients were asked to record the severity, duration and frequency of their migraine attacks. Data was analysed using t-test. p<0.05 was considered significant.
Results: The duration and severity of migraine attacks in Propranolol group were less compared to Nimodipine group (p<0.05). However, there was no statistical differences in the frequency of migraine of these two groups.
Conclusion: Propranolol seems to be more effective than Nimodipine in prevention of migraine headaches

Nasrin Roozbahani

Introduction: Dysmenorrhea is one of the most prevalent complaints of women which is due to Prostaglandin release and is treated by chemical drugs. Today regarding side effects of these drugs, scientists are increasingly moving toward using herbal drugs. This study is planned to comparison the effects of Thymus Vulgaris and Mefenamic acid on primary dysmenorrhea.
Materials and Methods: This is a clinical trial study. Target population was women suffering from primary dysmenorrhea and study population was women reffering to marriage consulting center. Based on α=0/5, β=0/20, sample size was calculated 214 which were divided into two groups randomly. Samples were asked to determine their pain severity before using the drug, by a visual scale (0-10cm). In the study group each sample cosumed 15 grams Thyme leaf brewed in a glass of water and in control group samples used 250mg Mefenamic acid capsules. Then pain severity was determined again 1, 2 and 3 hours after using drugs. Data was analysed by mean and standard deviation indexes and K-S, man-whitney and chi-square tests. Helsinki declaration was regarded at all stages of the research.
Results: Pain severity mean, before using the two drugs had no significant difference between groups. In each group, pain severity was significantly decreased before and after using the drug (p=0.05). But the rate of decreasing pain between the two groups showed no significant difference.
Conclusion: Regarding results, it seems both Mefenamic acid and Thymus Vulgaris decrease pain at the same level which seems to be due to Thyme,s antiprostaglandin and antispasmodic effects.

Comparison of Fluid Therapy for Resuscitation of Hemorrhagic Shock in Intact Rat and Hypothermic Kidney Denervated Rats

Hamid Farahani

Introduction: Recent studies have demonstrated that hypothermia after hemorrhagic shock (HS) can decrease need of fluid therapy and increase arterial pressure that results in increase the survival rate. But it has not been determined how hypothermia causes these beneficial effects. This study reviews hypothermia effects in this area.
Materials and Methods: This is an experiential study in which 24 rats were divided into four groups. Rats were anesthetized by pentobarbital. In groups 1and3, bilateral renal sympathectomy was done and in the groups 2 and 4 renal nerves remained intact and only lateral incisions were done to preserve similar conditions. Then rats underwent HS phase (phase I) for 90 minutes, by withdrawing 4-6 ml of blood during 10 mines. After shock induction, only in groups 1 and 2, body temperature was lowered to 32oC. At the end of phase I, rats underwent resuscitation phase (phase II) by reinfusion of blood & additional Ringer Lactate to retain normal arterial pressure. Stage II lasted 60 minutes.
Results: In hypothermic groups (1 and 2) in comparison to normothermic groups (3 and 4) there was less blood or fluids needed for resuscitation (p<0.05). Arterial pressure before shock was the same in all groups but at the end of phaseII was higher in hypothermic ones (p<0.05).
Conclusion: It seems that mild hypothermia has beneficial effects on survival of animals with HS. Although it is obvious that intact kidneys have vital role in maintaining body fluid balance during HS, but it seems hypothermic rats requires lesser fluid therapy even without nerve of kidney. More studies could be probably required to confirm this.

Insulin dependent diabetes mellitus, human leukocyte antigens

Introduction: Insulin dependent diabetes mellitus (IDDM) or type 1 diabetes is created by autoimmune destruction of insulin-producing beta cells of the pancreas in genetically susceptible individuals. The relationship between human leukocyte antigens (HLA) associated factors and susceptibility to IDDM disease, was reported by several investigators. Association with different HLA types depends also on the studied populations. The aim of the present study was to determine HLA antigens which represent a high susceptibility to develop the IDDM disease in this area. Materials and Methods: In this study, the prevalence of HLA class-I and II antigens has been determined in 31 Arakian patients with IDDM and 57 normal healthy controls with similar ethnic background and from the same geographical area. The typing of HLA antigens was carried out using standard microlymphocytotoxicity method. Results: A significantly higher frequency of HLA-A2, A3, B21, DR3 and DQ2 were found in IDDM cases compared to the controls. In contrast, HLA-DR2, DR7 and B53 were represented at a somewhat higher frequency in controls compared to the IDDM patients. Conclusion: These results indicate that HLA-A2, A3, B21, DR3 and DQ2 antigens contribute to susceptibility to IDDM independently and HLA-DR2, DR7 and B53 antigens maybe associated with prevention of IDDM in Arakian patients.
