  Background and Objective: Intradermal Purified Protein Derivative PPD test is a reliable test assessment of primary mycobacterial infection. In this test the specific antigen is Purified Protein Derivative (PPD). The reaction were assessed by touching, the induration's diameter after 48 &48hours. We compared the induration's size 48 and 72 hour in this study.

  Methods: At this semi experimental study a 5 unit PPD was administered to 120 healthy medical students.

  Results: The measurements made at 72 h were significantly (4.22 mm) (p<0.001) higher than those made at 48h (2.79 mm). The reading taken at 72 h were 1.47mm larger than at 48 h recovery. There were significant differences between induration size of 48 and 72h between male and female.

  Conclusion: This study demonstrates that, in adults, the size of the 5 U Monteux reaction is significantly larger at 72h compared to the reaction at 48h. We suggest to read PPD after 72 hours if the PPD is negative after 48 hours.

 Background and objectives: Chemotherapy-induced nausea and vomiting are the most important complications for cancer patients. Ginger is an effective herbal drug for the treatment of nausea and vomiting. It hasn’t any known side effects. In some countries, it is used for making of antiemetic drugs. The aim of this study was to determine the effect of ginger on the intensity of chemotherapy-induced nausea and vomiting in cancer patients .

 Method: This study is a randomized, cross-over, double – blinded, clinical trial that was done on 44 cancer patients undergone chemotherapy. In the first cycle of the study, patients were assigned by four block random allocation to receive one of the antiemetic regimens regimen A (routine and 1gr ginger) and regimen B (routine and 1gr placebo). After 28 days, in the next cycle of chemotherapy, another regimen was administrated A or B plus chemotherapy drugs., the severity of the nausea and vomiting was measured in 4h (1, 2, 3, 4) after second dose and at the end of the 24h after receiving the first dose by using VAS and kortila tools .The data were analyzed by independent student t - test and non-parametric test (Mann-Whitney U test) by using SPSS, version 16 software .

 Results: The results showed that the frequencies of nausea and vomiting in two regimen groups weren’t different, but nausea score was significantly decreased in ginger group, compared to placebo. Independent student t - test and Mann-Whitney U test also revealed a significant difference on nausea scores in 3rd and 24th hour post chemotherapy (p=0.06, p=0.01, respectively).

 Conclusion: In respect to low nausea score in ginger regimen, compared to placebo, it seems ginger using is a safe and simple method and it can be used as antiemetic drugs in patient undergoing chemotherapy

  Background & Objectives: Pain is one of the most common problems for which human have always been looking for efficient treatment. Several different factors may cause pain, but one of the most widespread reason is the application of some treatments and nursing measures such as intramuscular injection. The present study was designed to compare between the intensity of pain due to intramuscular injection by two different methods: Z- track and Air lock method.

  Methods: In this semi-experimental study, 60 volunteer female nursing students were included. The subject was injected with one milliliter of sterilized water two times within 24 hours: the first injection by Z method and the second one by the Air lock method. The intensity of pain was measured two times by a scale graded from zero to ten. The results were compared by using descriptive statistics and independent t-test by SPSS 12 software.

  Results: Our findings showed that the mean of pain intensity in Z method was 1.80 ± 1.90, and raised to 3.13 ± 2.33 in Air lock method. Moreover, the intensity of pain in these two different methods had significant difference (p<0.01).

  Conclusion: These results indicated that the pain caused by Z method is less than the pain felt through Air lock method. With respecting to these results the Z method is proposed as preferred method for intramuscular injections.

Introduction & objectives: Marital satisfaction is a very important aspect of a couple's relationship that is affected by various factors such as cardiovascular disease. The purpose of this study was to assess the sexual satisfaction based on the left ventricular ejection fraction(LVEF) in patients with coronary artery disease.
Methods: This descriptive  cross-sectional study was performed on 220 patients with acute coronary disease admitted to angiography ward of Shahid Beheshti Hospital of Kashan University of Medical Sciences in 2018. The data collection tools in this study included background and clinical information checklists and Larson's sexual satisfaction questionnaire. Data analysis was performed with chi-square, one-way ANOVA and univariate and multivariate regression test.
Results: The mean sexual satisfaction of all participants was 103.24±13.62. Their average sexual satisfaction in people with LVEF in range of >55%, 45-55%, 35-45% and <35% was 106.29±14.49, 105.95±10.12, 103.84±12.18 and 96.89±17.7 (p=0.041) respectively.
Conclusion: LVEF is an important factor in sexual satisfaction in patients with acute coronary disease and sexual satisfaction decreases by reducing of LVEF.

Background & objectives: The purpose of this study was to model the causal behaviors related to bullying based on the experience of child abuse mediating the role of emotional security.
Methods: Method of this research was correlational. The statistical population of this study included male high school students in Ardabil city in the academic year of 97-98 in which 385 people were selected as a statistical sample by cluster random sampling. Bernstein's Child abuse (CTQ) and Emotional Security Questionnaires were used to collect data. Data were analyzed using structural equation modeling using AMOS22 and SPSS22 software.
Results: The results of the study were in line with the hypotheses that showed child abuse (p<0.05) had a positive effect and emotional security (p<0.05) had a negative effect on bullying-related behaviors. Also, the fit of the proposed model has a good fit and the variable power of emotional security in mediating the impact of child abuse on bullying-related behaviors was confirmed.
Conclusion: According to the results, parents should be aware of the devastating consequences of child abuse on their children's mental and physical health and the importance of emotional security and safety in their children's healthy development, to prevent and reduce bullying-related behaviors. Teachers and school officials should also be aware of bullying and related behaviors to reduce and prevent harmful effects on students.

Background & objective: FoxO1 and STRA13 proteins play an important role in duplication and cellular metabolism, regulation of cell differentiation, apoptosis and reducing the spread of fat tissue in the body. The aim of this study was to investigate the effect of different intensities of aerobic training on the expression level of FoxO1 and STRA13 genes in subcutaneous adipose tissue of male Wistar rats.
Methods: In this experimental study, 32 male Wistar rats with a mean age of 8 weeks and weight of 237±33 gr were selected, and they were randomly divided into 4 equal groups including moderate-intensity aerobic training (MIT), high-intensity aerobic training (HIT), high-intensity interval aerobic training (HIIT) and control group. The training program was implemented 8 weeks and 5 sessions per week for the experimental groups,. Adipose tissue biopsy was performed 48 hours after the last training session to evaluate FoxO1 and STRA13 gene expression using  RT-PCR method. Data were analyzed using One-way analysis of variance test using SPSS 24 software at the significance level of p<0.05.
Results: The results showed that there was a significant difference in the FoxO1 gene expression level in the subcutaneous tissue of male Wistar rats between HIT and control groups (p=0.0001). However, no significant difference was observed between experimental groups. In addition, there was a significant difference in STRA13 gene expression level in the subcutaneous tissue between MIT (p=0.008), HIT (p=0.0001) and HIIT (p=0.009) groups and control group.
Conclusion: According to the results, aerobic exercise with variety of intensity is effective in controlling the genes expression rate involved in fat metabolism and by reducing the FoxO1 and STRA13 genes expression, they cause the duplication and reduce the expansion of fat tissue.
