[ relationship of spinal deformities with locomotion components of kepart test in elementary school students with dyspraxia]

Because of dyspraxia students have difficulty in some movements and deformity of the spine as a factor can lead to restriction of their movement, the purpose of the present study was to investigate the relationship between vertebral column deformities and components of the Kepart test in students with dyspraxia. The present descriptive analytical research is a cross-sectional study, involving the male elementary school students of Tehran in 2009. The participants were selected through multi-stage cluster sampling: Zone 4 was chosen by random from among the 22 municipal districts; 5 schools were selected by random from among many schools in the zone; finally, 1100 students were randomly selected. In the first step, we distributed the questionnaire about the conceptual - movement deficiency [validity 0.86]. Eighty students of 8 to 12 years with problems in at least 5 components [out of 14] participated in the Kepart test [validity 0.95]. From them, 34 students with the lowest scores were selected as the study subjects. Then, with the use of Spinal - Mouse machine, the vertebrate column deformities of students were studied from frontal and sagital aspects. For analyzing the data, Pearson's correlation coefficient was used in SPSS 13. The prevalence of deformities was flat back 40%, thoracic kyphosis 29.16% and thoracic scoliosis 20.83% in the subjects. A significant relationship [p=0.05, r=0.34] was found between lumbar lordosis and side walking in students with dyspraxia. Also, the prevalence of dyspraxia was 7.26%, and 2.18% suffered from severe dyspraxia. The results showed that the lower the amount of lumbar lordosis, the lower the students' ability to side walk

Effects of all-trans retinoic acid on the pancreas development in rat Embryo

Recent data shows that retinoic acid [RA] signaling is required for early pancreatic development in animals, whereas the effects of exogenous All-trans Retinoic Acid [ATRA] on gestation day [GD] 10 in later development have not been well documented. In this experimental interventional study, female rats, were randomly divided into two groups [experimental and control, n=5 each]. Animals in the experimental group received single dose [100 mg /kg] of ATRA orally on GD 10 and fetuses were observed on GD 18.The fetus pancreas [from both the experimental and control groups; each n=24] were processed for staining and followed by measuring the accumulation of pancreatic acinus and pancreatic ductile associated with the islets of langerhans. In addition, the mean diameter of pancreatic acinus, acinar cells and related nucleus were measured. Statistical analysis was done by student t-test, P value<0.05 being considered significant. In the experimental embryos on GD 18, the mean accumulation of pancreatic acinus [23.5%], and pancreatic ductile, associated with the islets of langerhans [76%] per field were increased. There was a significant difference in accumulation of pancreatic acinus [P< 0.0001] and pancreatic ductile, associated with the islets of langerhans [P< 0.0001], between the groups in this regard. The mean diameter of pancreatic acinus and the related nucleus were compared in the two groups, and results showed significant [P< 0.0001] decrease of this parameter in the experimental group. Results suggest that ATRA may have positive effects on proliferation, differentiation and maturation of pancreatic acinus and pancreatic ductile associated with the islets of langerhans

[Histomorphometerical effects of retinoic acid on red cells in rat's embryo]

All-trans retinoic acid [ATRA] has beneficial and teratogenicity effects when used in a variety conditions. The objectives of this study were to determine the effects of ATRA on the red blood cells [RBC] and platelets in rat's embryo. In this study Wistar rats were used. They were maintained on laboratory chow and tap water provided ad libitum. Adult virgin females [n = 10] were mated overnight with males of the same stock. A vaginal plug and smear observed, indicated day 0 of pregnancy. Single dose of 100 mg/kg of ATRA suspended in alcohol; corn oil [1:9] mixture and was given by oral intubations on the morning of gestation day [GD] 10 to experimental group. The control group was vehicle treated. The fetuses blood [controls and ATRA treated each, n= 23] were obtained directly from heart, as placental and mother circulation was continued and subsequently processed for staining [Gimsa] and followed by counting. The fetuses' blood cells were studied by light microscope and eyepiece [x40 for count, 100 for diameter. The number of RBC and also and platelets were significantly lower than those of control group [P<0.0001, P<0.04, respectively]. There was no significant relationship between diameter of RBC in treated and control groups. The present data showed that ATRA may has negative effects on proliferation and maturation of erythroid cell and platelet progenitors, without having any deleterious effects on the dime nation of cells, probably via events involving activation or suppression of specific genes

[ rare variation in branches of abdominal aorta]

Although there are many reports about variation of the branches of abdominal aorta, the present report is a very rare case that it has not been reported so far. The coeliac trunk is a wide ventral branch of abdominal aorta with 2.25cm long. The coeliac trunk divided into three branches: left gastric, common hepatic and splenic branch. Normally, the trunk has not any branches for small intestine after duodenum. In cudavr of a man with 65 years old who was dissected with grants method, the following variations were observed: a common trunk which is raised from common hepatic artery and divided to following branches: branches for pancreas near the neck and body of pancreas, a branch for head of pancreas, branches for duodenum, a huge branch for jejunum and ileum from right side, a huge branch for large intestine from left side, a communication branch between right gasteroepiploic and coeliac, arise cystic artery from common hepatic artery. Since the current report is a rare case, which has not been reported in any anatomical and clinical literatures so far, it may be an interesting and important case

result of 88 cycles of IUI in 75 infertile couples at 2001-2003 in Amir-Al-Momenin hospital

Intrauterine insemination with or without super ovulation has been proposed for the treatment of certain reproductive problems, Including male Sub Fertility, poor cervical mucus, presence of anti-sperm antibodies, minimal or mild endometriosis, and ovulation disorders refractory to previous attempts for ovulation and unexplained in fertility. To compare the pregnancy rates achieved by IUI in this center with other centers. A descriptive study in 88 cycles of 75 infertile couples during 2 years [2001 - 2003]. 67 cycles stimulated with HMG+ CC and 21 cycles with CC alone. The patients divided to 4 groups according to cause of infertility; G1: anovulatory, G2: male, G3: anovulatory + male and G4: unexplained. Pregnancy rate was 16% per patient and 13.6% per cycle of 12 pregnancies, 6 were Term deliveries, 2 ongoing, 2 abortions, 1 IUFD, 1 pre-term and 1 Twin Pregnancy. This study didn't show a statistical significant difference between HMG+ CC and CC cycles [P>0.85] and no differences existed between pregnancy rates in different causes of infertility. [0.1 < P < 0.2]: As in 67 cycles, HMG+CC has been used to stimulate the ovulation and the mean of using HMG has been 10, so this method can be used for the people who didn't have any suitable response to CC and also for the people due to having OHSS, fear to use HMG. And consequently, the consumption rate [HMG] can be reduced
