Abstract: Introduction: The aim of this study was to compare the behavioral disorders among children between the age of 7-12 who live in public or private care centers in Tehran.Material and Methods: The research method of causal-comparative and population of derelict and children 7-12 years institutionalized Tehran. Sampling was done and the way unit 128 children residing in public and private institutionalized were eligible to enter the study through behavioral assessment Rutter Scale (parents and teachers) were evaluated. A demographic list was also used. To analyze data collected, frequency table and U-Mann Whitney were conducted.Results: Results showed that abnormal behavior, social maladaptation, and the attention deficit disorder were significantly more in public than private centers. In antisocial behavior and hyperactivity-aggression no significant difference were observed. Anxiety and depression in governmental centers children is significantly higher than nongovernment centers. Children with poorly functioning families who were being held in both kind of facilities showed more behavioral disorders than orphan children.Discussion: It appears that private child care centers have been successful in working with orphaned children or those with uncaring parents. Skilled manpower and adequate distribution of resources among children (due to low numbers in each center) are considered to be part of the reason for this success.

Abstract: aquic conditions performed for paddy cultivation may cause many nutritional problems. clay mineralogical composition plays an important role in this relation by affecting many physico-chemical and biological characteristics of soils. three forms of k including unavailable, slowly available and readily available k, exist in equilibrium in the soil system. relationships between soil potassium forms with the clay mineralogical suite and physico-chemical properties were determined in 33 soil samples collected from five from paddy soils, two from kiwi fruit and one from citrus land pedons in the north of iran. mineralogical analyses showed that smectite, illite and vermiculite were the most abundant clay minerals in the studied soils. mean soluble and exchangeable potassium in paddy soils were rather low compared to non-paddy soils due to potassium fertilization in non-paddy soils. non-exchangeable potassium in the samples containing smectite as dominant clay mineral was lower than the samples dominated by vermiculite, hydroxy-interlayer vermiculite (hiv) and illite. inability of the studied soils for potassium fixation was related to prevailed montmorillonitic type of smectite, which its layer charge originates from octahedral sheet. significant correlations (0.56**, 0.54**, 0.56**) were obtained between exchangeable potassium and clay content, organic carbon and cation exchange capacity respectively. therefore, taking into account both exchangeable and non-exchangeable k beside clay mineralogy and physico-chemical properties gives better indications for k potential and soil-quality management, compared to exchangeable form of k alone.

Is Previous Tubal Ligation a Risk Factor for Hysterectomy because of Abnormal Uterine Bleeding?
Sanam Moradan,Raheb Gorbani
Oman Medical Journal , 2012,
Abstract: Objectives: Post tubal ligation syndrome (PTLS) is a term used to describe a variety of post tubal ligation side effects or symptoms. These include increased menstrual bleeding and hysterectomy. Whether or not post tubal syndrome is a real entity, it has been a subject of controversy in the medical literature for decades. Numerous studies have reported conflicting conclusions about these symptoms. In this study the incidence of hysterectomy for bleeding disorders among sterilized women was compared with the incidence of hysterectomy for bleeding disorders among non-sterilized female population of the same age.Methods: This study was carried out on 160 women, 38-52 years, who underwent hysterectomy in Amir University Hospital, Semnan, Iran, from September 2008 to September 2011. After gathering of data from medical records, in this study, the incidence of hysterectomy for bleeding disorders among sterilized women was compared with the incidence of hysterectomy for bleeding disorders among nonsterilized female population for the same age.Results: The mean age of the study group was 44/4±5/7 and the mean age of the control group was 45/2±5/3, (p=0.424).The mean parity of the study group was 3/8±1/8 and the mean parity of the control group was 3/5±1/4, (p=0.220). So, in regard to age and parity, two groups were matched. Hysterectomies were performed for 160 cases and abnormal uterine bleeding was the cause of hysterectomy in 67 cases. Among 67 cases, 19 cases (37.3%) had previous tubal sterilization + hysterectomy (study group) and 48 cases (44%) were not undergoing tubal sterilization but had hysterectomy for abnormal bleeding causes (control group). Statistical analyses showed that there were not significant differences between two groups, (RR=0.85; 95% CI: 0.56-1.28; p=0.418).Conclusion: The result of this study showed that previous tubal sterilization is not a risk factor for undergoing hysterectomy because of abnormal uterine bleeding.

African Journal of Biotechnology , 2009,
Abstract: Previously we isolated three native strains, Rhodococcus FRF, IPF and GAF from Tabriz and Tehran refineries soil samples in a search for flavin reductase gene (dszD). In this study, these three flavin reductase genes were isolated and identified by PCR using the nucleotide sequence of dszD gene from Rhodococcus sp. The amplified dszD DNA sequences were purified and cloned into the T-vector pTZ57R/T and then introduced to the E. coli DH5. Further sequence analysis revealed that the oxidoreductase genes of Rhodococcus FRF, IPF and GAF share high similarity to that of Rhodococcus erythropolis IGTS8. There were differences only in a few number of nucleotide. Also oxidoreductase enzymes in all strains consist of 193 amino acids that differ only in one amino acid which is located at stop condon of Rhodococcus FRF.

Abstract: Introduction: The harmful effects of smoking cigarette on body organs are well documented. There are more than 40 acoustic voice parameters and the effects of smoking cigarette on them are still studied . The aim of this study was to examine and compare some acoustic voice parameters between smoker and non smoker men. Material and Methods: In this cross–sectional study, some acoustic voice parameters including; fundamental frequency, jitter, shimmer, irregularity, contact quotient and elements of speech pattern were compared between 2 groups of men consisting of 20 smokers and 20 non-smokers. Each parameter was calculated using speech studio software and an electrolaryngograph. Results: The men’s voices differed on several parameters. The mean fundamental frequency in smokers was significantly lower (P > 0.001) than this one in non-smokers. The mean jitter, shimmer and irregularity of men who smoke were significantly higher (P > 0.001) than those mean in the men who did not. The mean silence among smokers was significantly higher (P > 0.001) than that mean among nonsmokers. In contrast, the mean of voicing in the men who smoke was significantly lower (P > 0.001). No significant difference was observed between the two groups with respect to contact quotient, nasality, and friction. Conclusion: Fundamental frequency is the most vulnerable acoustic parameter of voice in smokers. The higher means for jitter shimmer and irregularity of voice in men who smoke is most likely related to epithelial changes in the vocal folds, inflammation caused by cigarette smoking, and the neurologic effects of nicotine and other chemical materials of cigarettes. It seems that the increased time of silence during connected speech of smokers is related to the defective quality of the closed phase of vocal cords movement.

Abstract: Introduction: Skin tags are small, benign, soft and pedunculated skin tumors. A possible associationwith impaired carbohydrate metabolism has been suggested in previous studies, but the results are notconclusive. This study was performed in order to determine association between skin tag and diabetesmellitus.Materials and Methods: This study was carried out on 80 patients with skin tags as a case group and 80patients without skin tags as a control group that they were referred to Semnan dermatological clinics. Thenfasting blood sugar (FBS) were checked out in both two groups. In addition, height and weight weremeasured in all patients and body mass index (BMI) calculated for each of the patient.Results: 43.8% and 55% of patients were respectively female in the case group and the control group.Age mean (± SD) was 44.3±16.6 and 37.3±18.9 years in the case and control group, respectively. BMImean (±SD) index was 28.0±4.3kg/m2 in the patients with skin tag, whereas, it was 25.5±5.1 kg/m2 in thepatients without skin tag (P=0.001). Patients with skin tag had higher frequency of diabetes than patients inthe control group (27.5% vs. 5%) and also the case group showed a higher frequency of pre diabetes thanthe control group (20% vs. 15%). The probability of presence of diabetes mellitus in the patients with skintag was 6.82 times more than the patients in the control group (Odds ratio=6.82, 95% Confidence interval:2.06-22.56, P=0.002).Conclusion: Our data suggest that there is an association between skin tag and diabetes mellitus.Therefore, screening of patients with skin tag is recommended for early diagnosis diabetes mellitus

Abstract: Introduction: Substance abuse is one of the most common disorders that exert a high impact on the life of patients and their families. There are many treatment methods for Addiction. The purpose of the present study was to determine the effects of narcotics anonymous (NA) program on personality characters in substance abuse patients.Materials and Methods: This quasi experimental design was performed on 100 patients with substance abuse disorders that they had been randomly selected from those patients who were referred to psychiatric clinics and counseling centers in Esfehan in 2008. Then, the subjects were equally divided into two groups; experimental and control. All the patients carried out Eysenk test prior to any intervention and also a demographic questionnaire were filled out by all the subjects. Then, Eysenk test was performed on all the patients following the intervention. Changing in personality character in the experimental group (before and after the intervention) was compared with those of the control group. Results: The findings showed that narcotic program has significant effects on personality characters of experimental group to substance abuse in post test, but these effects are not significant in control group.Conclusion: According to the findings of this work, we suggest the effectiveness of NA program in changing personality characters of the patients with substance abuse

Abstract: Introduction: In recent century, the rapid growth of population threats life. This shows thenecessity of using contraception methods. In most women who use hormonal methods asacontraceptive method, uterine bleeding occurs and it result in that they stop using the methods andtherefore leads to unwanted pregnancies. In this study,we investigated the incidence of Abnormaluterine bleeding (AUB) in the different kinds of hormonal methods.Material and Methods: This study was performed on 390 married women with normalmenstruation and in age of 15-35 years who referred to Semnan health centers. They had used one ofthe hormonal methods at least more than one month. 130 women used DMPA, 130 women usedminipill and 130 persons used LD tablets. All women who had AUB following using one of thehormonal methods were considered as AUB due to the hormonal method, excepet those had AUB foranother reason that it was proved by sonography or other investigations. Patients’ information wereexactly recorded in questionnaires.Results: The incidence of metrorrahgia in minipill and DMPA was more than its incidence for LDmethod and the incidence of oligomenorrhea in DMPA method was more than minipill and LDmethod. In addition, the incidence of amenorrhea in DMPA method was more than minipill. Theperiod of using of these methods had reverse effect on the incidence of oligomenorrhea,polymenorrhea and menorrahgia but it had a direct effect on the incidence of amenorrhea. Theincidence of menorrahgia in the 15-20 years old persons was more than other ages.Conclusion: The incidence of AUB in LD method is very low and seems it might be the mostsuitable hormonal contraceptive method, in case women aren't prohibited from using LD tablet.Regarding the high incidence of abnormal bleeding in minipill method, using another method insteadof minipill method for contraception is recomened to women
