Abstract

 Background & Objectives: Regarding the admitted cases at early infancy in Tabriz Pediatrics Medical Center, this research was carried out to determine the role of Hep.B. vaccination in the incidence of ITP.

 Methods: We studied all patients’ admission files in Tabriz Pediatrics Center from 1993 to 2002. The patients were under 6 months of age and hospitalized with the impression of ITP. There were 25 infants whose ITP was diagnosed upon their clinical findings, blood counts and bone marrow aspiration and confirmed by exclusion of other causes of thrombocytopenia. Hep. B. vaccination has been included in routine immunization in Iran since 1993. In order to compare the incidence rate of ITP before and after 1993, we also sought all ITP patients’ files at the same age group who had been admitted to Tabriz Pediatrics Center during the decade before the beginning of routine Hep.B. vaccination (i.e. 1982 to 1992).

 Results: This study shows a considerable increase in incidence of ITP in infants under 6 months of age between 1993 asnd 2002 compared to the decade before the beginning of Hep.B.vaccination, which is statistically significant (P=0.0029).

 Conclusion: Although there is no facility to measure antibodies in Iran and many other countries, and this is one of the reasons for lack of proof for existence of a relationship between vaccination and ITP incidence, the study of cases in two different periods may strengthen the role of Hep.B. vaccination in the occurrence of ITP at early infancy.

Abstract

 Background & Objectives: The cognitive processes such as attention, thinking, memory and recall have effective role on the child’s confrontation with daily life problems. The psychological disorders are among those impairments which may severely affect these processes. Researches have shown that schizophrenia can impair children’s cognitive processes to a great extent. The aim of this research was to compare the comprehension, lexical Knowledge, memory and recall in children with schizophrenia, conduct disorder and brain damage.

 Methods: The sample of this causal-comparative research consisted of 80 children (8-13 years old) suffering from schizophrenia, brain damage and conduct disorder as well as a group of healthy ones who were selected from among in and out-patients referring to psychology and neurology wards of Emam Hossein health care center in 2004 (20 subjects in each group). The instruments employed in this research were WISC-R (comprehension, vocabulary, digit span) and Recall Test of Babcoch.

  Results: The one way analysis of variance showed significant differences between the children with schizophrenia, conduct disorder, brain damage and non-patient in comprehension, lexical knowledge, memory and recall (p<0.01). The LSD test showed that comperhension, lexical knowledge, memory and recall in children with schizophrenia were more impaired compared to children with conduct disorder and brain damage. Moreover, comprehension, lexical knowledge and memory in children with conduct disorder were more severely impaired than children with brain damage. However, the recall was better in children with conduct disorder than those with brain damage (p<0.01).

 Conclusion: The results showed that schizophrenic children have comprehension, lexical knowledge, memory and recall more impaired than those suffering from conduct disorder and brain damage. The timely recognition of the cognitive abnormalities seems necessary to have a better diagnosis and choose effective treatment and remedial strategies to cope with them.

Abstract

  Background & Objectives : One of the first steps in diagnosis of pleural effusion is distinction between exudative and transudative types. The aim of this study was to assess C – reactive protein (CRP) level as one of the diagnostic marker for differentiation of exudative from transudative pleural effusions.

  Methods : In this descriptive and sectional study, 80 patients with confirmed pleural effusion were assessed. These patients were divided into two groups based on Light´s criteria. Serum and pleural CRP were measured with Latex Agglutination Test.

  Results : Out of 80 patients with pleural effusion 26 were transudative (32.5%) and 54 were exudative (67.5%). In exudative group, 72.2% of cases were CRP positive (1+ to 3+), and in transudative group, only 38.5% of cases were CRP positive (p < 0.05). There was no significant differences between different exudative pleural effusion etiologies (infectious and non infectious, malignant and non malignant and tuberculosis) and the number of CRP positive cases (p > 0.05). The rate of CRP positivity in exudative pleural effusion group was more than transudative group (p < 0.05).

  Conclusion: According to our study it seems that CRP criterion could help in distinction between exudative and transudative types of pleural effusion.

Abstract

  Background & Objectives :Heart rate deflection point (HRDP) plays an important role in predicting anaerobic threshold and monitoring athletes training schedule. Despite some research, the physiological mechanisms involved in occurrence of the HRDP remains to be fully elucidated. The objective of this study was to survey of the agreement between Heart Rate Deflection Point (HRDP) and the Potassium Turn Point (KTP) in young athlete men.

  Methods :Thirty young men athlete volunteer (Mean ± SD age= 20 ± 1.21 years height = 176 ± 7.34 Cm and weight = 6.58 ± 5.66 Kg) were selected as subjects. Hofmann protocol was used to cause the HRDP. One week later and after determining the HRDP by using the S.Dmax method, subjects performed Hofmann protocol again and blood samples were taken from left forearm vein in five phases, simultaneously. The amount of potassium was measured directly by the Flamephotometer.

  Results :According to the results of study, the HRDP and KTP were occurred in average in 78% HRmax and 79% HRmax, in all of the subjects, also there was a highly agreement between HRDP and KTP (158 3.84 vs. 159 3.88 b/min). HRDP & KTP were occurred in third phase, simultaneously.

  Conclusion: Based on these results, exercise induced increase in serum potassium during Hofmann incremental cycle ergo-meter testing protocol can be one of the mechanisms of the occurrence of HRDP.

Abstract

 Background and Objectives: Three major semen parameters that involves on male infertility are sperm count, motility and morphology. In 50% of couples referring to physicians, because of infertility, male factor, solely or accompanying with female factor is responsible of infertility. Some of drugs are used to improve the semen parameters. The goal of this study was to study the effect of pentoxifylline on semen parameters (count, motility, morphology, volume of semen).

 Methods: Sixty one patients with impairment in semen parameters were selected and semen samples requested from each participant for analysis before treatment. Then patients were treated with pentoxifyllin, 400 mg three times a day, for three months. After that we took semen specimens again and analyzed them.

 Results: Mean total sperm count in case group before treatment with PF was (17 millions) and after treatment with PF reached to (21 millions). In 68.9% of patient, Sperm count increased (p<0.001) Mean motile sperm percent in case group before treatment with PF was 19.42% and After treatment with PF reached to 28.78% and 88.52% of patient this parameter increased (p<0.001). Parameter motility showed the most important after treatment. Mean normal morphology of sperm percent in case group before treatment with PF was 24%and after treatment with PF reached to 26.39% and in 32.8% of patient this parameter increased (p<0.001).Mean semen volume in this group before treament with PF was 1.95ml and after treament with PF reached to 1.93 ml. There was no significant variation in semen volume after treament with PF. (p=0.321)

 Conclusion: Results show that Pentoxifylline has significant efficacy for increasing sperm count, motility and morphology correction (specially for sperm motility). Considering that oral PF is safe and cheap, with easy application, we can use it for improving semen parameter’s quality before performance ART.

Abstract

  Background & objectives: Hydaticosis is a zoonotic helminthic disease of human and other intermediated hosts in which larval stages of the tapeworm Echinococcus granulosu transfect human. The liver and lung are the host tissues for the hydatid cyst . It is unknown which mechanisms are involved in infertility of the cyst and suppression of the fertile cyst. This study was aimed to evaluate the expression of the apoptosis inducing-ligands such as TRAIL and Fas-L in germinal layer of the cyst and human normal tissue surrounding the cyst that is one of the unknown host innate immunity mechanisms against the hydatid cyst.

  Methods: In this study, four isolated hydatid cysts were used which had been diagnosed in patients by radiography and parasitological examination in Mashhad Ghaem hospital. Furthermore, the germinal layer of the cyst and accompanied normal peripheral tissues were separated by scalpel in sterile conditions. After homogenization, expression of TRAIL and Fas-L genes were studied by semi-quantitive RT-PCR method.

  Results: The TRAIL and Fas-L showed significant higher level expression in germinal layer of infertile cyst than the fertile cyst and host normal tissues.

  Conclusion: The host tissue-induced apoptosis of germinal layer of the fertile cysts is probably one of the infertility mechanism in patients with hydaticosis

Abstract

  Background and Aim: Birth in the 21st century is characterized by interventions. That interventions increase the risk for mother and baby without improving outcomes. The aim of this study was to compare the effect of physiological birth and routine normal delivery on some of maternal and fetus outcomes.

  Methods: This quasi-experimental study was performed on 160 pregnant women. The participants were allocated in two groups of physiological birth (n=80) and routine normal delivery (n=80). Inclusion criteria were as following: Apgar score between one and five dilatation between three and four cm maternal age between 18-35 years gestational age between 37-40 weeks cephalic presentation and neonatal birth weight of 2500-4000 gr. Physiological birth care included labor begins on its own, freedom of movement throughout labor, continuous labor support, spontaneous pushing, no separation of mother and baby. Routine birth cares include routine interventions in labor or birth. Rate of cesarean, Apgar score and neonatal intensive care unit were evaluated in both groups. Data were analyzed by SPSS 16. The t-test, chi-square and Mann Whitney were the statistical tests of choice.

  Results: Rate of cesarean was significantly different between two groups (p=0.005). First minute Neonatal Apgar score was significantly different (p=0.011), but fifth minute Apgar was similar in both groups (p=0.470). The transmission to neonatal intensive care unit had also significant difference among two groups (p=0.029).

  Conclusion: The present study showed that the physiological birth is safe. It seems that the physiological birth decreases the rate of cesarean and transmission to neonatal intensive care unit, also improves the first minute neonatal Apgar scores.

Abstract

  Objective: Spinal cord injury (SCI) has become an especially challenging target in experimental neuroscience. Approach into the spinal cord is the interface among all different types of spinal cord injury modeling. The lower thoracic spinal cord has generated special interest due to the lower limbs’ spinal pattern generator position and presence of relative scales for behavioral assessment. However, a clear method with which to approach the thoracic spinal cord has yet to be determined.

  Methods : A total of 20 animals were subjected to this study. Following induction of anesthesia, the 10th thoracic vertebra were positioned, and muscles were retracted. Using the high speed rotary, the vertebral lamina were carefully thinned. As a final point, the reduced lamina was meticulously removed away to expose underlying spinal cord. Loco motor behavioral test (BBB) was implemented before and after surgery procedure.

  Results: This manuscript has presented the stepwise method to expose rat thoracic spinal cord. Whole procedure took less than an hour. Animals acquired complete BBB loco motor rating score before and after surgery indicating the safety of procedure.

  Conclusion: This article introduces simple and practical approach for the rat lower thoracic spine. The anatomical orientation, anesthesia , postoperative management , and common problems are discussed .

Abstract

  Background & Objectives: Chronic renal failure (CRF), also known as chronic kidney disease, caused by devastated nephron mass of the kidney results in uremia. Hypertension, diabetes mellitus and glomerulonephritis are common etiologic factors of CRF. This condition causes miscellaneous oral manifestations especially in diabetic patients. The aim of this study was to comparison oral manifestations of diabetic and non-diabetic uremic patients undergoing hemodialysis.

  Methods: A total of 95 patients who undergoing hemodialysis in Razi hospital in Rasht city participated in this descriptive analytical study. Patients were divided into two diabetic and non- diabetic groups. Oral cavity examinations were done by latex gloves and single use mirror. Objective and subjective oral manifestations such as xerostomia, bad taste, mucosal pain, uremic odor, coating tongue, petechial, purpura, pale oral mucosa, ulcer, dental erosion and candida infection were recorded in questionnaire. After gathering of information, the data were analyzed by SPSS 15 software using t-test and chi square statistical test.

  Results: About 60% of patients (57 person) were men and 40 % (38 person) were women. The mean age of patients was 48 years (range of 20 -76 years). Common subjective oral manifestation in both groups was xerostomia and most common objective oral manifestations were pale oral mucosa, uremic odor and coating tongue respectively. The DMFT index in diabetic group was significantly higher (17.3±7.63) than non-diabetic patients (12.4±8.26). There was no significant statistical correlation between the time of dialysis, number of dialysis appointment during the week and objective and subjective oral manifestations in two groups.

  Conclusion: Although, the present study has shown an increase in oral manifestations in diabetic patients undergoing hemodialysis relative to non-diabetic group, but this increase was not statistically significant. On the other hand results of our study have indicated significantly higher DMFT in diabetic group in comparison with the non-diabetic group. So patients with diabetes mellitus undergoing hemodialysis need to more oral and dental health care.

Abstract

  Background & objectives : Epileptic seizures accompany disturbances in learning, memory, and cognitive skills. With regard to antiepileptic potential of curcumin and its beneficial effect on memory, the effect of its administration on learning and memory in kainate-epileptic rats was investigated.

  Methods: Forty male rats were divided into sham, positive control ( valproate-treated epileptic), epileptic, and two curcumin-treated epileptic groups. Rat model of epilepsy was induced by unilateral intrahippocampal administration of 4 μg of kainate per rat. Rats received intraperitoneal injection of curcumin (50 and 100 mg/kg) daily for 1 week before surgery. For evaluation of learning and memory, initial (IL) and step-through latencies (STL) were determined using passive avoidance test and alternation behavior percentage was obtained according to Y maze test.

  Results: Regarding IL, there was no significant difference between the groups. In contrast, STL significantly decreased in curcumin-50-treated epileptic group (p<0.05) (a change from 263.1 to 184.5 s). However, this parameter significantly increased in curcumin-100-treated epileptic group as compared to epileptic group (p<0.01) (a change from 263.1 to 220.3 s). In addition, STL was also significantly higher in valproic acid-treated epileptic group versus epileptic group (p<0.05) (a change from 145.7 to 210.3 s). Alternation percentage was also significantly higher in curcumin-50- and curcumin-100-treated epileptic groups relative to epileptic group (p<0.05) (a change from 60.5 to 77.6 and 80.3%).

  Conclusion: Curcumin could dose-dependently enhance the consolidation and recall in epileptic animals and could improve spatial memory in such animals.

Abstract

Background & objectives: Temporal lobe epilepsy is associated with neuronal apoptosis. Curcumin has antioxidant and anticonvulsant activities, therefore this study was conducted to assess involvement of Bax and Bcl2 in protective effect of curcumin in epileptic rats.

Methods: 28 rats were divided into sham, curcumin-pretreated sham, epileptic (kainate), and curcumin-pretreated epileptic groups. Experimental model of epilepsy was induced by intrahippocampal administration of kainic acid. Rats received curcumin at a dose of 100 mg/kg. Finally, Nissl staining and Bax and Bcl2 immunohistochemistry were conducted on hippocampal sections and data were analyzed using one-way ANOVA and unpaired t-test. The p-value less than 0.05was considered statistically significant.

Results: Induction of epilepsy was followed by a significant seizure and curcumin pretreatment significantly reduced seizure intensity (p<0.01). In addition, there were no significant differences between the groups in Nissl staining of CA3 area neurons. In addition, Bax positive neurons were observed in CA3 area in kainate group and significantly decreased in curcumin pretreated rats (p<0.05). Meanwhile, Bcl2 positive neurons were also moderately observed in kainate group and curcumin pretreatment significantly increased it (p<0.05).

Conclusion: Curcumin pretreatment exhibits anticonvulsant activity in epileptic rats. It also decreases the expression of pro-apoptotic protein Bax and significantly enhances the expression of anti-apoptotic protein Bcl2 and hence could reduce neuronal apoptosis.

Abstract

Background & objectives: Hip muscles insufficiency plays a significant role in deterioration of patellofemoral pain syndrome (PFPS), which can be manifested as myofascial trigger point (MTrPs) in hip muscles. Then, our purpose was to determine the prevalence of MTrPs in the gluteus medius (GMe) and quadratus lumborum (QL) muscles and to investigate the effect of a therapeutic intervention on pain intensity and hip abductor muscles isometric strength in patients with PFPS.

Methods: Forty volunteer subjects (20 patients and 20 healthy) participated in the study. Latent MTrPs in GMe and QL were evaluated and a handheld dynamometer was used to measure peak isometric strength test (PIST) for hip abductors. Patients with PFPS having MTrPs in GMe were randomly divided into either a treatment group (Mean age±SD: 23.2±4.3 years) or control (Mean age±SD: 24.4±4.6 years). The therapeutic intervention included trigger point pressure release (TrPPR) and Kinesio Taping® (KT). Pain intensity and PIST for hip abductors were assessed at baseline and after intervention in both groups.

Results: There is more significant patients with PFPS having latent MTrPs in GMe and QL than the healthy counterparts (p<0.001). Using TrPPR and KT significantly decreases pain in such patients (p<0.001); however, no significant effect was observed on hip abductors peak isometric strength (p>0.05).

Conclusion: Concomitant using of TrPPR therapy and KT method can decrease pain intensity in individuals with PFPS. Further studies are required to understand the underlying mechanisms.

Abstract

Background & objectives: The present study examined the gonadotoxic effects of ciprofloxacin antibiotics and protective effects of L-carnitine.
Methods: In this study, 20 NMRI mice were divided into four groups: control, ciprofloxacin, L-carnitine, L-carnitine-ciprofloxacin (each group included 5 animals). The control group received normal saline, the treatment group 1 received 12.5 mg/kg ciprofloxacin, the treatment group 2 received 100 mg/kg L- carnitine and the treatment group 3 received 100 mg/kg L- carnitine and 12.5 mg / kg ciprofloxacin simultaneously. All animals were treated by intraperitoneal administration for 15 days. Testis and epididymis were collected to evaluate sperm parameters (sperm count, motility, morphology and viability).
Results: In the ciprofloxacin group, a significant decrease in sperm count, sperm viability, sperm motility, progressive sperm motility and normal sperm as well as a significant increase in rotating sperm motility, sperm without movement, head and tail abnormalities were observed (p≤0.05). A significant increase in sperm count, sperm survival, motility and progressive sperm motility, normal sperm and a significant decrease in rotating sperm motility, sperm without movement and head abnormalities in the L-carnitine-ciprofloxacin group were observed (p≤0.05); however, the reduction in tail abnormalities of sperm was not significant.
Conclusion: L-carnitine improves sperm parameters in the adult mice treated with ciprofloxacin.

Abstract

Background & objectives: Cancer is the leading cause of death worldwide. In this study, the cytotoxic effect of hydroalcoholic extract of Colutea persica leaf and its synergic effect with doxorubicin were investigated on MCF-7, LNCaP and SKM (as control) cell lines.
Methods: Hydroalcoholic leaf extract of Colutea persica was prepared using maceration method and ethanol 70%. Breast cancer (MCF7), prostate (LNCaP) and fibroblast (SKM) cell lines were cultured in microplates (96 wells) and exposed to various concentrations (10, 7.5, 5, 2.5, 1.25, 0.625, 0.312 and 0.156 mg/ml) of plant extract and doxorubicin (20, 80, 320 and 640 nM) solution. The synergistic effect of 20 nanomol of drug and 0.156 mg / ml of the plant extract was investigated. MTT assay was employed to evaluate the cytotoxic effects of the extract on cell lines at different time intervals (24, 48 and 72 hours). Staining with annexin V and propidium iodide (PI) was used to identify different types of cell death either necrosis or apoptosis.
Results: The plant extracts had cytotoxic effect and cell viability rate was lower than fibroblasts. At different times, the concentration of 10 mg /ml of the extract showed the most growth inhibition of breast and prostate cell lines. The combination effect of plant extract with doxorubicin on cells was not significant (p<0.01). The Annexin V/PI flow cytometry results showed that the percentage of initial apoptosis, delayed apoptosis and necrosis in treated cells increased compared to untreated cell.
Conclusion: Hydroalcoholic extract of Colutea persica leaf inhibits the growth of cancer cells and induce apoptosis in breast and prostate cancer cells.

Abstract

Background & objectives: Zinc sulfate binds to the R group of some amino acids, such as histidine and cysteine, resulting in protein precipitation. In an ELISA and colorimetric experiments, we determined the optimal concentration of zinc sulfate to precipitate hemoglobin, which in turn affects the level and activity of Caspase 3 in red blood cells.             
Methods: Osmotic stress was induced on red blood cells under hypertonic and hypotonic conditions. An isotonic condition was used as a control without osmotic stress. The cells were incubated at 37oC for 15 min and 24 hrs. Different concentrations of zinc sulfate were set up experimentally, stepwise after the lysis of RBC samples with ultrasound waves and removal of cell membranes by centrifugation. Zinc sulfate was allowed to bind to hemoglobin at different time intervals at room temperature. Afterward, hemoglobin was precipitated at various time intervals through centrifugation. The supernatants were then measured by ELISA and colorimetric methods for Caspase 3 level and activity.
Results: The optimal conditions were found to be 6 mM zinc sulfate, 10 min incubation at room temperature to bind zinc sulfate to hemoglobin, and 30 min centrifugation at 3000 rpm to precipitate hemoglobin.                                                       
Conclusion: This study showed that zinc sulfate with a concentration of 6 mM precipitates and removes hemoglobin without affecting the level or activity of Caspase 3.

Abstract

Background: The main purpose of this study was to investigate the effects of dry needling on pain and pain pressure threshold (PPT) in patients with non-specific chronic low back pain (NSCLBP).
Methods: 29 patients with NSCLBP were randomly allocated into two experimental (N=14) and control (N=15) groups. The dry needling intervention was considered for quadratus lumborum, gluteus medius, and lumbar multifidus, in 6 sessions, and subjects of the control group followed their routine lifestyle. The measurements included pain and PPT, which were evaluated in the pre-test, post-test, and follow-up periods. The pain was a variable that had a three-month follow-up assessment. Analysis of variance of combined measurement with repeated measurement and Benferoni's post hoc test were used to investigate the effect of the intervention on the outcome measurements.
Results: Three sessions of trigger point dry needling did not lead to a significant change in pain. However, after five sessions of dry needling, a significant decrease in pain was observed (p<0.05), and the positive changes significantly remained until one and three months after the end of the intervention (p<0.05). Furthermore; significant changes in PPT scores were detected following five sessions of trigger point dry needling treatment (p<0.05). These changes remained constant in the one-month follow-up assessment (p<0.05).
Conclusion: Dry needling for the trigger points of the QL, GM, and LM muscles can improve pain intensity and PPT in patients with NSLBP.
