Abstract
Background and Aim: The optimal maternal position for the most comfortable, efficient delivery has long been a source of contention. The purpose of this study was comparison labor pain in first stage of labor.
Materials and Methods: In this study 56 primigravida women that had 2-5 cm cervical dilation and 5-10 minute frequency of contraction randomly assigned in two groups. Group A began with 30 min in the sitting position and group B began with 30 min supine position, followed by 30 min supine sitting position. Therefore maternal position in group A was sitting- supine- sitting- supine, and in group B was supine- sitting-supine sitting.
Each 30 min period the woman asked to rate the labor pain using visual Analugu scale (VAS)
Results: There were no statistically significant differences between mean pain in upright and supine position in all women.
Conclusion: We conclude that a certain position can not provide less pain through the first Stage of labor. Therefore is no reason to discourage patients from adopting the position of their choice in labor

Abstract
Abstract
Background and Aim: Developmental processes are mediated by cell surface and extracellular matrix (ECM) interactions that are regulated by the molecular mechanism. The aim of this study was to determine Glycoconjugates terminal sugars distribution and the changes during kidney development in rats using Lectinhistochemical technique.
Materials and Methods: Thirty Wistar Rat embryos at different stages from days 14 (E14) to 18 days of gestation were fixed in formalin, embedded in paraffin and cut into 5µm thickness sections serially. The sections were incubated with different HRP-lectins from Lotus tetragonolobus (LTA), Maclura pomifera (MPA) and Ulex europeus agglutinine (UEA-I). Staining intensity was determined by means of blind method and the sections were graded to compare different embryonic stages.
Results: Our findings showed that the reactions of MPA with podocyts started at E14 and increased afterwards (p<0.05). Mesenchymal cells reacted with MPA on E14, E 16 and disappeared at E18 (p<0.05). Collecting duct reaction with MPA was moderate on E 16. Mesenchymal cells reaction with UEA-I was moderate on E14 to E16 but decreased on E18 (p<0.05). A weak reaction was observed in collecting duct with UEA-I on E16. Proximal and distal tubules as well as collecting ducts showed a weak reaction with LTA in E18. No reaction was observed in Podocytes. Mesenchymal cells reacted on E14 but did not react on E16 and E18 with UEA-I lectin.
Conclusion: According to the results, it is concluded that distributions and changes of glycoconjugates with terminal sugars L-Fuc (α2-4) GlcNAc, Gal (β1-3) GalNAc and L-fuc (α 1→3) Gal (β 1-4) Glc, are regulated during rat kidney development.

Abstract
Aims: Hypomagnesemia is observed in 15-10% of patients admitted to the hospital and in 40-60% of intensive care units patients. This study was done to investigate the prevalence of hypomagnesemia in patients undergoing elective surgery in the first 24 hours of hospitalization.
Methods: In this interventional cross-sectional study, 60 patients undergoing elective abdominal surgery with general anesthesia and were admitted to the ICU were selected using simple sampling method. Age, gender, height, weight, body mass index (BMI), SAPS number, the probability of mortality based on SAPS, sodium, total magnesium, calcium, potassium and plasma phosphorus levels within 24 hours of hospitalization and the total urinary excretion of magnesium in the first 24-hour of hospitalization at ICU was measured and recorded. Independent T and Chi square tests were used for statistical analysis.
Results: Serum magnesium, sodium, potassium, calcium and phosphorus and demographic characteristics (age, gender, weight, height and BMI), did not show any significant correlations with total magnesium deficiency of body after loading of magnesium dosage. Also there was no significant correlation between total magnesium deficiency of body after magnesium dosage loading and the duration of being at ICU. But there was a significant difference in total magnesium deficiency of body after dosage loading of magnesium with expected mortality rate of patients using SAPS parameter (p=0.013).
Conclusion: Magnesium Serum level is an unreliable indicator of hypomagnesemia. The greater the total magnesium deficiency of the body, the worse the prognosis is.

Abstract
Aims: Any damages to the nerve fiber blocking connection with the neurons cell body (vital cell substances synthesis part), can lead to degenerative changes in proximal and distal parts of the damaged neuron. Some plants due to the antioxidant substances are effective in the survival and division of the neurons. This study aimed to investigate the effect of alcoholic extract of Salvia chloroleuca leaves on destruction of spinal cord anterior horn alpha motoneurons after sciatic nerve injury in rats.
Materials & Methods: In this experimental study 24 male Wistar rats aged 12weeks and weighting 200-250gr were provided. The animals were divided into 4 (each=6) control, damaged, damaged + treatment with 50mg/kg alcoholic extract and damaged+treatment with 75mg/kg alcohol extract groups. To calculate the alpha motoneurons in the anterior horn of the spinal cord in the right side the dissector method was used. Data were analyzed using Minitab 13 software by independent T and ANOVA tests.
Findings: The mean density of alpha motoneurons in spinal anterior horn in control group was 1711.5±47.4, in damaged was 730.7±33.4, in damaged+treatment with 50mg/kg alcoholic extract was 1211.2±34.8 and in damaged+treatment with 75mg/kg alcoholic extract was 987.4±36.8. Mean difference between both treatment groups and damaged group was significant (p=0.001).
Conclusion: Salvia chloroleuca leaf extract increases the density of alpha motor neurons in the anterior horn of the spinal cord in rats with sciatic nerve injury, and this increase in neuronal density is associated with the intake of the extract.

Abstract
Aims: Using chemical drugs to treat disease often is associated with side effects. Recently, using herbal medicines, which have fewer side effects, has flourished to treat many diseases, including infertility. This study was done aimed to investigate the effect of palm pollen aqueous extract on sexual hormones and follicle cells numbers in adult female BALB/c mice.
Materials & Methods: This experimental study was done in animal house of Shiraz University of Medical Sciences in 2012. 40 adult female BALB/c mice were divided into 5 control, sham and experimental groups receiving 100, 200 and 400mg/kg of the body weight of the extract groups each with 8 members. Levels of testosterone, estrogen and progesterone were measured by radioimmunoassay and ovarian follicles numbers were counted after separation of the ovaries and sectioning and staining using Hematoxylin & Eosin by light microscopy. The results of hormonal assays were analyzed based on One-way ANOVA and Duncan's multiple range tests using SPSS 18 software.
Findings: A significant increase was observed at the level of testosterone, estrogen and progesterone compared to the control group only in the experimental group 3 (receiving 400mg/kg palm pollen extract) (p<0.01). Also, only in the experimental group 3 a significant increase was observed in the number of secondary follicles (p<0.05) and the number of antral follicles (p<0.01) compared to the control.
Conclusion: 400mg/kg palm pollen aqueous extract increases the amount of sexual hormones and secondary and antral follicle numbers in adult female mice.
