Kangaroo mother care is a new method for baby care with several advantages. A universally available and biologically sound method of care for all newborns, with three components: skin-to-skin contact, exclusive breastfeeding, support to the mother-infant dyad. This study designed for evaluating Kangaroo mother care on infantile colic. "n"nMethods: This study was a randomized controlled trial. From 1th may 2008 to 1 may 2009 a total of 70 children, aged 3-12 weeks with persistent colic symptoms were studied. The children were referred to Sheikh clinic, Mashhad, Iran, because of excessive crying. Normal mother-infant pairs were recruited at 3 to 12 weeks of age after obtaining baseline for two days. Subjects divided randomly to kangaroo care or conventional care group and mothers in both groups filled diary for seven days. "n"nResults: In the beginning of the study, the infants in kangaroo care group had 3.5 hr/d crying and after the intervention, it decreased to 1.7 hr/d, the difference were significant (p<0.05). But there were no difference in feeding duration between two groups (p=0.2). Awake and content (normal behavior) behaviors were significantly increased in the kangaroo care group (p=0.001). Sleep duration was significantly increased in the kangaroo care group (p=0.02)."n"nConclusions: Kangaroo care may be used as a simple and safe method for treatment of infantile colic.

Asian Journal of Plant Sciences , 2012,
Abstract: Cynodon dactylon is widely distributed in Iran in diverse habitats. In this study, morphological variation of 46 populations of this species was evaluated based on 52 qualitative and quantitative characters to reveal the true taxonomic situation of the species. High morphological variation with no significant correlation with geographical and ecological conditions was observed. Among the morphological characters, presence of hair on leaf and sheath surfaces and spike color had major role on groupings in dendrogram. Based on the results of this study, presence of pilose hairs on leaf surfaces and outer surface of leaf sheath were shown to be stable diagnostic characters in detecting infraspecific taxa and accordingly, the species C. dactylon present in Iran two varieties: var. dactylon and var. villosus Regel. A morphological description for this species and taxonomic key of the varieties are provided.

Koomesh , 2009,
Abstract: Introduction: Inadequate weight gaining is common cause of prolong hospitalization, increased costsand complications in preterm and low birth weight infants. For these reasons, the present study wasundertaken to investigate the effect of oil massage on weight gaining in hospitalized preterm infants inNICU of Ghaem hospital.Materials and Methods: This clinical trial was performed in neonatal intensive care unit of Ghaemhospital between April 2007 and April 2008. Sampling was nonrandom and samples were dividedrandomly to three groups: 1) massage with oil 2) massage without oil and 3) control group. Finally, dailyweight gaining was compared between three groups. In this study, 121 preterm neonates (age < 28 days)were selected and randomly divided to three groups: 1) oil massage group 2) massage without oil group3) control group. In three groups, weight gaining was recorded daily and compared together.Results: There was no significant differences in mean gestational age, height and head circumference(p>0.05) between three groups. The Mean of weight gaining on day seven was respectively 105±1.3g,52± 0.1g and 54 ± 1.3g in the MCT oil massage group, the group with massage without oil and thecontrol group. These differences were statistically significant only between the MCT oil massage groupand massage group (P=0.002) and also between the MCT oil massage group and the control group(p=0.000).Conclusion: In preterm neonates, MCT oil massage can promote weight gaining, probably bytranscutaneous absorption.

Iranian Journal of Pediatrics , 2011,
Abstract: Objective:It has been demonstrated that newborns feel pain completely. Thus, they should be treated with this in mind. Recent research showed that non-pharmacological interventions such as "Kangaroo Care" may be useful for decreasing pain in newborns. We tried to determine the effect of kangaroo care on the pain intensity of vaccination in healthy newborns. Methods:This study was a randomized case-control clinical trial. Subjects were 60 healthy full-term newborns delivered in a general Hospital, in Iran, from March to July 2006. They were randomly assigned to case and control groups. The case group received 30 minutes skin to skin contact, whereas infants in the control group were put, wrapped in a blanket, aside the mothers. Behavioral changes of newborns were evaluated and observed 2 minutes before, during, and 3 minutes after the intervention. All procedures were filmed. An assistant who was blinded to the study, scored behavior changes using Neonatal/Infant Pain Scale. Heart rate and oxygen saturation levels as displayed on the pulse monitor and duration of crying were recorded using a stopwatch. Findings:Mean pain intensity during the intervention v was significantly lower in the case group (P<0.006). Mean pain intensity 3 minutes after intervention was also significantly lower in the case group (P<0.021). Mean duration of crying was significantly lower in case group as well (P<0.001). Conclusion:Kangaroo care may be used to decrease pain intensity in newborns undergoing painful procedures.
Prevalence and Predisposing Factors of Retinopathy of Prematurity in Very Low-Birth-Weight Infants Discharged from NICU
Reza Saeidi,Ahmad Hashemzadeh,Sina Ahmadi,Shagayeg Rahmani
Iranian Journal of Pediatrics , 2009,
Abstract: Objective: Retinopathy of prematurity (ROP) is a disease of the eye caused by disorganized growth of retinal blood vessels resulting in scarring and retinal detachment. All preterm babies are at high risk for ROP, and very low birth weight is an additional risk factor. An increased incidence of ROP is expected in Iran because of improved survival of low birth weight and premature babies, and it is obvious that pediatricians and ophthalmologists are concerned about prevention and timely treatment of ROP in these children. To asses the real situation of ROP in our NICU we studied its prevalence and risk factors. Methods: This was a retrospective analysis of premature infants with birth weight of ≤1500 grams or gestational age of ≤32 weeks, admitted April 1, 2005 to March 28, 2006, to the Neonatal Intensive Care Unit of Qaem Hospital, Mashhad, Iran. The collected data of 47 cases in this cross-sectional study are analyzed by SPSS (Mann_Whitney, t-Student). Findings: Forty five infants were included in the study. Out of these, 4 (8.5%) developed ROP (inclusive all stages). Our analysis revealed that low gestational age, sepsis and respiratory distress syndrome were independent predictors for the development of ROP. Conclusion:The frequency of ROP in our hospital was lower than the range reported in developed countries, and our risk factors were a little different.

Zahedan Journal of Research in Medical Sciences , 2012,
Abstract: Background: Patent ductus arteriosus or patent arterial duct (PDA) is a condition in which a structure called the ductus arteriosus, normal in fetal life, remains into infancy and onwards, when it should have disappeared. Thus, in this study we want to discuss about frequency of its symptoms and risk factors. Materials and Methods: It is a descriptive study which has been done among 100 newborns registered in Ghaem Hospital of Mashhad. Sampling was gathered easily.Results: The most prevalent symptom among newborn babies was systolic heart murmur (89%). According to the obtained risk factors, hypoxia (71%) and acidosis (70%) are followed by prematurity (41%). Out of all registered newborn babies 68% were suffering from associated disorders.Conclusion: For achieving an on-time diagnosis of PDA, clinical examination of heart and respiratory symptoms must be examined very precisely. Newborn babies must be examined in terms of two risk factors: prematurity and light weight.

Pakistan Journal of Biological Sciences , 2007,
Abstract: In February 2001, one-year bareroot cypress (Cupressus sempervirens var. horizontalis) seedlings were replanted in plastic pot in a lowland nursery located in southern coast of the Caspian Sea (north of Iran). Soils of pots consisted of 1:1 sand:clay (A), pure sand (B), 2:1 sand:clay (C), 1:1:1 sand:clay:organic matter (D), 1:1:2 sand:clay:organic matter (E). In each soil treatment a high value of survival and growth was appeared in July and progressively decreased till November. In each month the seedlings grown on rich soils (D and E) had mostly greater growth and survival than on infertile soils. At the end of the first growing season seedling vitality differed significantly among the soils but did not differed notably in soil A with those in other soils. Survival rate was highest in the rich soils (D and E). Stem length as well as collar diameter performed the least growth on the poor soils (B and C). Like other characteristics measured, survival responded better to soils containing organic matter (D and E). It is concluded that generally characteristics of cypress seedling are suited by adding organic matter to sandy soils. This is while that poor nutrient available soil such as soil A produces a proper growth for cypress seedling, too.

Journal of Isfahan Dental School , 2011,
Abstract: Introduction: The main factor involved in the failure of endodontically treated teeth is crown reconstruction rather than root canal treatment itself. The present study compared stress distribution in pre-fabricated and cast post-and-cores by finite element analysis. In addition, the effect of post material was evaluated. Method and materials: In this cross-sectional descriptive-analytical study, an extracted sound human mandibular second molar was embedded in an acrylic resin cylindrical mold. Axial cross-sections were prepared by abrasion and photographed; the images were transferred into a computer software program and a three-dimensional solid model of the tooth was prepared. A load of 10.43 MPa was applied on a 23-mm2 surface area of the occlusal surface at an angle of 45°. Finally, different restoration models for pre-fabricated and cast posts were designed and the effect of post material was analyzed.Results: Cast posts generated less stresses compared to pre-fabricated posts; however, pre-fabricated posts were more conservative form the stress location viewpoint. Regarding stress concentration, gold posts were more favorable in comparison to titanium posts because stress concentration in gold posts takes place in the cervical region, so that if root failure occurs, reconstruction is possible. Conclusion: Cast posts result in less stress in roots compared to pre-fabricated posts. Except for gold cast posts, all other cast posts are more dangerous in relation to stress distribution. Key words: Dental stress analysis, Finite element analysis, Post-core, Technique.

Abstract: The Bourgeoisie Revolution or Jay`s National Return during 1867-1868 paved way for the relatively fast growth of capitalism in Japan. The dispersion of Feudalism was a history and large factories were being built all over the country. The state officials who were under pressure of farmers who were protesting the feudalism relationship had no way than making some reforms in agriculture. According to one of these reforms during 1872-1873, only the ownership of those would be recognized who had been an owner in advance; that is, those who had inherited plots of lands. The mortgage lands were owned by those who had paid money for mortgage. This reform gave important benefits and privileges to the landowners and rich villagers, merchants and usuries who had taken villagers` lands on lien. The villagers lost their ownership right on one third of the lands they used to possess: common lands, including forests, ranges and pastures were put in possession of emperor and changed him to the most powerful landowners of the territory. The owners of small lands and village units who were indebted in all their properties and an increase in land tax had made their burden heavier immediately found out that they were not able to keep the lands they had obtained in recent reforms and thus, they changed into lease villagers with no ownership right. Their lands were owned by large land owners and rich farmers and for all their lives, they had to be depended to those wealthy landowners.
