Abstract: 

Introduction: Antiphospholipid antibodies may be detected in normal pregnancies and may cause thrombosis, recurrent fetal loss, placental infarction and preeclampsia. In this study the possible differences in antiphospholipid antibody titer between healthy pregnant women and preeclampsic cases was examined.Materials and Methods: The antiphospholipid antibody titer in 50 healthy pregnant women with 50 preeclampsia cases without the history of thrombosis and autoimmune disease was compared. IgG and IgM anticardiolipin antibody was measured by immunoassay methods. Teclot kits were used for Lupus-like anticoagulant antibodies. Data was analyzed by Chi-square test, p<0/05 was considered significant.Results: There was no association between antiphospholipid antibody titer in healthy and preecalamptic group. In normal pregnant women and preeclamptic cases there was 6% and 8% Lupus like anticoagulant antibody, 12% and 4% IgG anticardiolipin antibody and 26% and 30% IgM anticardiolipin antibodies respectively.Conclusion: Despite the evidence of prothrombotic state during preeclampsia, it is unlikely that antiphospholipid antibodies represent a risk factor for preeclamptic women as compaired to healthy pregnant women.

Abstract: 

Introduction: Vasectomy is a kind of the permanent contraception method, which is easy to use with few complications. But in recent years it is thought that there may be a relationship between vasectomy and prostate cancer. In this study this relationship is discussed. Materials and Methods: In a case-control study, 150 samples were selected, 50 with previous history of vasectomy in 5 years ago and 100 normal non-vasectomy samples as control group. PSA was determined in all samples with ELIZA method. Parameters such as (age, BMI, smoking) in two groups was identical. Data was analyzed by Pearson correlation, T and Chi square tests.Results: PSA was higher in vasectomy samples than non-vasectomy ones (P=0.017). Also PSA was increased with aging. Conclusion: Results showed that both vasectomy and aging increased PSA. But we need more study for finding vasectomy as the risk factor for prostatic carcinoma.

Abstract: 

Introduction: Kindling is an animal model of epilepsy induced by repeated stimulation of the brain‏. The amygdala has been the focus of interest, due in large part to its role in epilepsy induction and in fear conditioning in both human and rats. The purpose of the present study was to evaluate whether low electrical stimulation of foot pad of rats during fear can facilitate kindling susceptibility. Materials and Methods: In this experimental study 25 wistar male rats were trained for two way active avoidance learning in the shuttle box and on the basis of escape response were divided into fast and slow learning rats. Then each group was randomly assigned into two groups. ‏Test groups received conditional and unconditional stimulus and control groups received conditional stimulus for ten days. To induce kindling pentylenetetrazole was administered to rats and seizure parameters were eveluated. Data were analyzed using one way ANOVA and Tukey's test. Results: Results demonstrated that slow learning rats in compare to fast learning ones were more prone to kindling. Repeated electrical stimulation of slow learning rats during fear conditioning facilitates kindling induction as compare to fast learning group. Conclusion: It seems that slow learning rats when exposed to repeated electrical stimulation after fear conditioning have more susceptibility to show seizure as compare to fast learning groups. It seems that neurons in the amygdala of slow learmhg rats have more pxitability.

Abstract: 

Introduction: Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii. The migration of the parasite in blood as well as some organs like liver may cause some changes in physiological and biochemical indices in infected individuals. These may change the level of some indices like urea, total bilirubin, total protein, and albumin. The present investigation was conducted to study alteration of some liver functional indices of rats which were experimentally infected with Toxoplasma gondii. Materials and Methods: 80 non-infected rats & 60 non-infected mice were selected. Rats were divided into two groups of 60 test and 20 control rats. The test group was infected intraperitoneally with 5x104 tachyzoites. Every 3 days for 60 days, three rats from test group and one rat from control group were bled. Standard techniques were used for urea, bilirubin, total protein and albumin tests. In addition, the livers of infected rats were searched biologically for presence of the parasite using intrapritoneal injection in mice method. Results: The results indicated that, Toxoplasma cyst was present in the liver of infected rats within 6 to 27 days post infection. The parasite was disappeared in liver after 28 days of infection. Biochemical results indicated that, urea from 6th to 60th day, total bilirubin from 6th to 27th day, albumin and total protein from 6th to 12th day post infection were increased but decreased to normal values afterward.Conclusion: Generally, temporary alteration of some biochemical indices during experimental infection of rat with toxoplasmosis may occur. The alteration mainly is due to the parasite migration to various tissues of the animal and it shifts to the normal condition following cyst formation in brain or muscles.

Abstract: 

Introduction: To improve painlessness quality and increasing the time of block and also for more painlessness after Cesarian surgery opiates are used in spinal anesthesia with blocker drugs in two ways: intravenous and intrathecal. The main goal of this research is to make a comparison between effects of intravenous and intrathecal fentanyl injections in elective Cesarian.Materials and Methods: In this double blind clinical trial study, 50 patients who were selected for elective Cesarian surgery were divided into two equal groups, and each group recived 75-100mg lidocain as a blocker agent. Then 12.5 microgram fentanyl was injected intravenously for one group and equal dose intrathecaly for the second group. Then vital signs and some side effects such as nausie, vomiting, itching and shivering were recorded for 6hours and blood pressure under 90mmHg for 30 minutes. Results were anlyzed whit T test and SPSS soft ware.Results: In this study, the time of painlessness for intrathecal fentanyl was 135.4 minutes and in intravenous group were 106.2. It was also found that in intrathecal fentanyl group and intrravenous fentanyl group, blood pressure under 90mmHg was 72% and 56%, nausia 52% and 32%, vomiting 20% and 12%, and shivering 12% and 16% respectively. Itching was not seen.Conclusion: The average time of analgesic effect of fentanyl in intrathecal group was significantly more than the other group. Nausia, vomiting, low blood pressure and shivering were more incident in intrathecal group but there were no meaningful different between them.

Abstract: 

Introduction: It has already been shown that diagonal band of broca has a regulatory effect on cardiovascular system. In this study we electrically stimulated the horizontal limb of the diagonal band of broca (hDB) to find its effect on blood pressure and heart rate. Materials and Methods: In this experimental study 34 rats were anesthetized with urethane and hDB was stimulated (80-150 microamperes for 15 sec) by a silver electrode coated with glass except for its tip. Blood pressure and heart rate were continuously recorded by a computer. Paired t-test was used for comparison of the prestimulation data and the maximum changes after the stimulation. Results: The results showed that electrical stimulation caused a significant decrease in blood pressure and heart rate. The maximum changes for long-term responses were 9.39 ± 1.13 mmHg for mean blood pressure and 15.4 ± 3.19 for heart rate. For short-term responses the maximum changes were 9.08 ± 1.4 mmHg for mean blood pressure and 7.5 ± 2.36 for heart rate. Conclusion: It is possible that glutaminergic system of the hDB suppresses the vasopressin release from hypothalamus, thereby decreases the blood pressure, and suppresses the sympathetic flow to the heart, thereby decreases the heart rate.

Abstract: 

Introduction: Emphysematous cystitis is a rare form of acute infection of the bladder which most cases are seen in diabetic patients. Most infections are due to E.coli and Klebsiella species. Predisposing factors are diabetes mellitus, recurrent urinary tract infections, bladder outlet obstruction and neurogenic bladder. CT-scan is the most sensitive method of diagnosis that detects air within intramular of bladder that is patogonomonic of the disease. In this case report we reported two cases of emphysematous cystitis.Cases: The first case was a 73 years old diabetic women who was admitted due to acute renal failure after cholecystectomy. During hospitalizotion, after remission of renal function, she developed fever, abdominal pain, hematuria and progressive abdominal distention. In physical examination she had generalized abdominal tenderness with dominance in the lower abdomen without rebound tenderness which with observation of air in intramural bladder by CT-scan, diagnosis of emphysematous cystitis was confirmed and the patient was treated and improved. The second case was a 37 years old diabetic women. She was reffered to the hospital because of nausea, recurrent vomiting and abdominal pain. In physical examination she had severe hypotention, generalized abdominal tenderness that was dominant in the lower abdomen and abdominal mass in suprapubic area. Suspicious to emphysematous cystitis, pelvic CT-scan was ordered. By observation of air in intramural bladder, emphysematous cystitis was confirmed. Patient was treated with antibiotic, insertion of fouly catheter and was improved. Conclusion:Undiagnosing or delaying in initiating appropriate treatment can lead to peritonitis secondary to intraperitoneal perforation of the bladder, septisemia and ultimately death of the patient. Timely diagnosis and aggressive therapy are important for the survival of these patients.
