Abstract
Introduction & Objective: Asthma is the commonest cause of
being admitted in hospital and missing school among children. It is
the commonest chronic disease among them as well. Although the
disease may cause a lot of deaths and financial loss , it is
preventable . Findings have revealed the various contributions of
environmental factors to the incidence of asthma.This study is an
attempt to recognize some influential factors in the incidence and
recurrent of asthma among children aged between 6 months to 6
years in Yasuj.
Materials & Methods: It is of cross- sectional descriptive
analytical type of study carried out with two groups, each of which
consisting of 90 children .The first group, the healthy ones, was
taken as control group and the second, with asthma ,taken as
case group . Enough care was taken in selecting uniform
members in control group. Afterwards, questionnaires were
prepared and filled by pediatricians when visiting the children in
health centers. The collected data were analyzed using SPSS.
Results: This study showed a significant relationship between
smoking , background of allergy within the immediate family
members and development of asthma. However there was no
significant relationship found between the educational status of
parents, breast feeding in the first six months and the incidence of
asthma.
Conclusion: Bearing in mind the contribution of smoking within
the family to the development of asthma in family members with
genetic susceptibility to the disease , the need for educational
cultural programs encouraging the reduction of smoking within
families particularly in enclosed spaces like homes is urgent and
should be satisfied .

Abstract
Introduction & Objective: The Ministry of Health and Medical Education of Iran established maternity facilities in order to provide a safe delivery and reduce deliveries at home in rural areas. However, a few of deliveries in Kohgilouyeh and Boyerahmad province took place in these centers. Therefore, the aim of this study was to determine the delivery status and factors influencing the pregnant women’s tendency to choose the place of delivery.
Materials & Methods: This descriptive study was carried out on 747 participants in the rural areas that were covered by maternity facilities in the first three months of 1384. Data were collected by a self-structured questionnaire whose validity and reliability had been determined previously. Data of age, education level, parietal status, antenatal cares, decision-maker for the place of delivery, geographical access to maternity facility centers and the cause of avoidance of referring to the centers were determined asking the women. Data were analyzed by SPSS software and using X2 statistical test.
Results: The results showed that overall 31% (230 cases) of deliveries took place at home and 51% (384 cases) at hospital, but only 18% (133 cases) of deliveries took place at maternity facility centers. There was a significant difference in antenatal education by midwives between women who delivered at home and those that delivered at maternity facility centers, showing that more educated women have managed to deliver at the maternity facility centers (p < 0.001). 58% of mothers had selected their delivery place by themselves, but in others the delivery place was selected by their mothers, mothers-in-law, their husbands, etc. Almost 79% (181cases) of mothers who delivered at home announced that geographical access (long distance) to the maternity facility was major problem. In addition, there was a significant association between literacy, living place and the number of previous pregnancies with selection of delivery place (p< 0.005).
Conclusion: Findings showed that the most important cause of avoidance of referring to maternity facility centers, from women’s point view, was geographical access to maternity facility centers as well as antenatal education by midwives.

ABSTRACT:
Introduction & Objective: Nowadays the extensive changes in lifestyle resulted in an increase in consumption of fast food. This type of food, because of using deep–fat frying, may contain some toxic or unfavorable substances which have adverse effects on consumers’ health. The aim of this study was to determine the peroxide value of edible oils which are used in restaurants and sandwich shops in Yasouj city.
Materials & Methods: This descriptive study was carried out on all sandwich shops (n=36) and restaurants (n=12) in Yasuj city in 2006. All samples and questionnaire data in restaurants and sandwich shops were collected at 11:30am and 12:30pm respectively based on a national standard protocol, number 493, by a food expert. The peroxide value was determined based on national standard procedure, number 4179, in a food laboratory and the acceptable limit was defined as 7 meq/kg.
Results: Findings of this study showed that in terms of health rules and regulations, at least 50% of oils used in restaurants and 70% in sandwich shops were unfavorable. Peroxide value of 58.3% of oils in restaurants and 97.3% in sandwich shops was greater than the acceptable limit.
Conclusion: These findings have shown that the health rules and regulations for the oils are not exercised in Yasouj restaurants and sandwich shops and this can have adverse effects on consumers’ health.

Abstract
Introduction & Objective: Neonatal jaundice is observed in the first week of birth among 60% of mature and 80% of immature neonates. This epidemic puts a lot of cost on the society. Today, phototherapy is used for the treatment of neonatal jaundice. Reducing the treatment period decreases the hospitalization costs. The Purpose of this study was to determine the effect of Zizphus Jujba extract and phototherapy on reducing both Bilirubin concentration and also the hospitalization period of neonatal jaundice patients.
Materials & Methods: This was a clinical-trial study which was conducted at Imam Sajjad Hospital of Yasuj in 2009. 121 of the hospitalized neonates were chosen and divided into 2 groups: case group (63 neonates) and control group (58 neonates). 1 cc of the Zizphus Jujba extract per each kilogram of body weight was orally given three times a day to the case group. Also phototherapy was used in the case group. Phototherapy was the only treatment used for the control group. The Bilirubin concentration of the hospitalized patients was measured two times a day in the hospitalization period. The collected data was analyzed by the SPSS software using t-test.
Results: The mean and standard deviation of the Bilirubin concentration in the control group before the intervention were 20.9±2.3 milligrams per 100 and after intervention was 12.27±1.23 milligrams per 100 while in the case group before intervention was 22.3±0.05 and after intervention was 12.27±1.01 milligrams per hundred. A significant difference was seen between the case and control group before and after intervention (p=0.001. Moreover, a meaningful reduction of the hospitalized days and a meaningful increase of excrement and urine in the case group were observed.
Conclusion: This study revealed that administration of Zizphus Jujba extract with increasing amount of excrement and urine of the neonates can lead to Bilirubin discharge and can be effective on curing neonatal jaundice.

Abstract
Introduction & Objective: Evidences have indicated that the Ventral Tegmental Area (VTA) is the major source of dopamine (DA) neurons projecting to cortical and limbic regions involved in cognitive and motivational aspects of addiction. Also, studies have indicated that the Ascorbic acid (vitamin C) can reduce the dependency symptoms of opioids such as morphine via effect of activity on dopaminergic neuron in VTA. For this reason, the aim of this study was to assess the effects of ascorbic acid on the amplitude of Ventral Tegmental Area field action potential in morphine-exposed rats.
Materials & Methods: Forty male Wistar’s rats were used in this experimental study conducted at Yasuj University of Medical Sciences in 2010. Animals were randomly divided into four groups after electrode implantation and recovery period: 1. No- Vit C and No-Addicted group (nVitC.nA) 2. Vit C and No-Addicted group (VitC.nA) 3. No- Vit C and Addicted group (nVitCA) 4.Vit C and Addicted (VitC.A), The Vit C groups received 500 mg/kg of Vit C during 20 days. For addicted groups morphine was administrated once daily for 20 days. In the 20th day, the field potential recording was accomplished. Two-way ANOVA was used for data analysis followed by the Tukey test for post hoc analysis. Results were considered significant at P < 0.05.
Results: This study shows the exposure to morphine declined the power of Delta and Beta bands (p<0.05) and Vit C solely enhance power of Theta and Beta (p<0.05, p<0.001) in VTA nuclei. Furthermore, Vit C could alter power of some bands which were affected by morphine. Therefore it seems that Vit C has an increasing effects on them (p<0.05).
Conclusion: Although the effect of Vit C on power of the VTA bands is not well known, but it is supposed that this phenomenon can be related to alteration in activity of dopaminergic neuron in the brain.

Abstract
Introduction & Objective: Some of natural and synthetic products have antioxidant properties which protect the liver against the destructive factors. This study aimed to investigate the effect of Zizphus Vulgaris extracts on mice liver.
Materials & Methods: This experimental study was conducted at Yasouj University of Medical Sciences in 2010 on 30 healthy adult male Wistar rats. Animals were randomly divided into five equal groups: the control group (receiving, olive oil), control group (receiving olive oil and carbon tetrachloride and three intervention groups (receiving different dose of carbon tetrachloride and olive oil) groups. The intervention group was given daily doses of 200, 400 and 600 mg per Kg of Zizphus Vulgaris extract by gavage respectively. After 45 days, the amount of liver enzymes, total protein, albumin and bilirubin in animal’s sera were measured. Data were analyzed by the SPSS software, using ANOVA and t-test.
Results: The concentration of total protein, albumin, AST, ALT, ALP in test groups I, II and III receiving Z.Vulgaris extract (200, 400 and 600 mg/kg weight) compared with control group were statistically not significant. Consumption of Z.Vulgaris reduced the bilirubin concentration in test groups I and II but this decrease was significant only in the test group I
Increasing of Z.Vulgaris dose in the test group III (600 mg Z.Vulgaris per kg body weight) showed increase in the level of serum bilirubin. Increase in the ratio of liver weight to body weight of rats in groups I and III in comparison with control groups was noticed although this difference was not statistically significant. Findings of this study revealed that dosage of 600 mg/kg extract of Z.Vulgaris caused significant improvements in CCl4 induced liver necrosis (P <0.01) and reduced portal cells inflammation (P <0.01). Dose of 400 mg/kg of Z.Vulgaris induced some destruction and necrosis of liver cells in animals but significant reduction of portal cells inflammation was seen.
Conclusion: Considering the obtained results, it seems that Ziziphus vulgaris fruit extract has shielding effects against toxins on liver cells.

Abstract
Introduction & Objective: Asthma is a chronic inflammatory airway disease. Asthma affects one in 13 school age children and is a leading cause of school absenteeism. It seems that prevalence of asthma is increasing wordwide. Many factors are identified and reported as factors related to asthma. This study was carried out to determine the prevalence of asthma and associated factors in 600 children under six years using logistic regression and probit.
Materials & Methods: This cross-sectional study was conducted on 600 children under six years old. Questionnaire was constructed based on ISSAC questionnaire and its reliability was determined with a pilot study and calculated by the Cronbach's alpha equal to 69 percent. Cluster sampling based on household records as clusters was performed. Questionnaires were completed by trained staff under supervision of an expert person and by interviewing parents and children.
Results: The prevalence of asthma was estimated to be 3.10 (7.89 to 12.78) percent. Based on fitting models to data, factors such as gender, maternal nutrition, exclusive breast feeding to 6 months, smoking at home by a family member and having a history of respiratory allergy in families were significantly associated with asthma prevalence (p-value ≤ 0.05).
The results also demonstrated that the both models are almost identical in evaluating the data.
Conclusion: This study showed that estimated asthma prevalence is equal to average prevalence reported in Iran. Protective factors, such as exclusive breast feeding as a strategy can be appropriated in children's health care programs and should be much more considered.

Abstract
Background & Aim: Cryopreservation of oocytes is an essential part of reproductive biotechnology. The objective of the present study was to investigate the effects of exposure to combination of cryoprotectants and vitrification on immature mouse oocytes with or without cumulus cells.
Methods: This was an experimental study conducted at Yasouj University of Medical Sciences in 2010. Immature oocytes with and without cumulus cells were isolated from ovaries of mice 4-6 weeks of age. They were vitrified in conventional straw using ethylene glycol (EG), dimethyl sulfoxide (DMSO) and sucrose as vitrification solution or exposed to vitrification solution without subjected to liquid nitrogen. After warming, oocytes were assessed for nuclear maturation and fertilization. The collected data were analyzed with one-way ANOVA and Tukey test.
Results: Survival and fertilization rates in vitrified oocytes with cumulus cells were significantly lower than the control group (p<0.05). Maturation rates in exposure groups were significantly lower than the vitrified and control groups (p<0.05). The fertilization rate increased significantly in all experiment and control groups with cumulus cells in comparison with denuded oocytes (p<0.05).
Conclusion: Germinal vesicle stage oocytes in the presence or absence of cumulus cells can be vitrified successfully. Exposure to cryoprotectants can decrease the developmental competence of GV oocytes. Presence of cumulus cells can increase the fertilization rate in IVF procedure.

Abstract
Background & aim: Peripheral nerve injuries which can lead to a physical disability. If the defect is very low, direct suture without tension on both ends of the cut nerve regeneration is considered as a standard procedure. Otherwise, to reconstruct the axons, the gap must be filled by graft material in order to the guidance. Due to the similarity of the matrix tubular skeletal muscle and nerve muscles graft was used to repair in this study.
Methods: In the present experimental study, 42 female Wistar rats were divided into three groups and underwent surgery. In the first group a narrow strip of muscle was prepared by freezing – thawing, and later sutured between the distal and proximal sciatic nerve. In the second group, the gap caused by muscle graft was regenerated and the nerve growth factor and laminin was injected into the graft. In the control group, the two ends of the cut nerve were hidden beneath the adjacent muscles. Next, a group of rats with sciatic functional index was investigated for the behavioral. On the other group were examined for histological studies after two months.
Results: Sciatic functional index and Mean counts of myelinated fibers in two graft groups compared with the control group was significant) p<0.05). Statistical analysis was performed using ANOVA test.
Conclusion: co-axially aligned muscle grafts were an appropriate alternative substitute for repairing. It seems that the nerve growth factor and laminin have a positive role in axonal regeneration and functional recovery acceleration.

Abstract
Background & aim: Breast cancer is the most common cancer among women and one of the factors threatening the health of women worldwide. Leptin is a 16 kD glycoprotein hormone produced predominantly by white adipose tissue. Leptin binds to receptors in the hypothalamus and plays a key role in regulation of metabolism. Both leptin and leptin receptor have recently been implicated in processes and progress leading to breast cancer initiation. The aim of this study was to identify if there is association between leptin and pathological indexes in patients with breast cancer
Methods: 45women with breast cancer were enrolled. Serum leptin levels of patients were measured by the ELISA method. Pathological information such as stage of the breast cancer, Hormonal receptor (ER, PR) and Her2 status in these patients were determined.
Result: Results revealed that the patients who were in stage one and two, the mean serum leptin level was (34.18±21.22 ng/ml) And patients who were in stage three and four, the mean serum leptin level was (32.21±21/93 ng/ml). Also the mean serum leptin levels in patients whose receptor status of ER, PR and HER2 positive were (35.90±23.55, 35.74±23.91and 37.02±24.25ng/ml), respectively. The Patients whose receptor status of ER, PR and HER2 negative were 26.64±13.13, 28.17±14.26and31.32±19.9ng/ml respectively. No significant association was found between leptin leveland stage of the breast cancer, hormonal receptor (ER, PR) and Her2 status in Patients with Breast cancer(p>0.05).
Conclusions: In this study, no association was found between serum leptin level and pathological indices in women with Breast cancer in Yasuj, Iran.

Background & aim: Cadmium is a toxin which reduces the ability of the reproduction in humans .Different antioxidants damaging effects of toxins are eliminated .The purpose of this study was to investigate the protective effects of lycopene and Ellagic acid induced by cadmium chloride on the gonadal tissue of newborn rats during pregnancy. Methods: In the present experimental study, 30 adult female Wistar rats (180-200 gr) were prepared and maintained in standard conditions. The female rats were used for mating with the male. After observation of vaginal plaque, pregnant rats were randomly divided into 5 groups of 6 rats. Group I (normal): They were given normal saline in 13 days during pregnancy. Group II (Control): Cadmium chloride (1.5 mg / kg/ IP) was injected and normal saline was given to them in 13 days of during pregnancy. Group III: Cadmium chloride (1.5 mg / kg/ IP) was injected and ellagic acid (10 mg/kg/orally) in 13 days were injected during pregnancy. Group IV: Cadmium chloride (1.5 mg / kg/ IP) was injected and copene acid (20 mg/kg/orally) was injected in 13 days of during pregnancy. Group V: Cadmium chloride (1.5 mg / kg/ IP) was injected and ellagic acid (10 mg/kg/orally) and lycopene acid (20 mg/kg/orally) were injected in 13 days during pregnancy. After postpartum, Neonatal rats were anesthetized with ether. Animals were dissected, then the testes and Ovaries were removed and transferred to 10% formalin solution. After tissue processing, tissue sections were prepared and H&E stained. Data were analyzed by SPSS software and ANOVA test. Results: Average number of Sertoli cells ,spermatogonia ,Leydig, and the number of seminiferous tube in control group were compared to other groups that were treated with lycopene - ellagic acid and ellagic acid had been reduced-proves to be significant(P <0.05). Average diameter of seminiferous tube in control group compared to other groups that are treated with lycopene - ellagic acid and ellagic acid had been reduced-proves but is not significant. Mean primordial follicle diameter and number of primordial of ovary tissue in control group compared to other groups that were treated with lycopene - ellagic acid and ellagic acid had been increased-proved to be significant(P <0.05). Conclusion: The results showed that the combined treatment of ellagic acid and lycopene-ellagic acid may have reduced the toxic effects of cadmium chloride and may have improved the process of replicating the sex cells.
