Background & Objective: The Acquired Immunodeficiency Syndrome (AIDS) is in its third decade and has become a pandemic disease that threatens the world population. Educational programs are well known as the most effective strategy to preventing the AIDS. The purpose of this study was to determine the knowledge and attitude of participants about AIDS and to test the effects of an AIDS education program on it. Materials & Methods: This case-control study was conducted during 2005. 149 Red Crescent personnel in Golestan, Iran. The sample subjects participated in a pre/post intervention study. The activity consisted of a workshop 90 minutes in length, in conjunction with educational material. A 13-item questionnaire was used as the gauging tool. Results: 47% of subjects had adequate knowledge about AIDS. Mean level of knowledge in post-test exam was significantly higher than pre-test one (P<0.0001). Individuals with higher educational level (high school and university) had lower knowledge in pre-test (P=0.001), but the difference in pos-test was not significant. A significant relationship was shown between the history of participation in previous AIDS education programs and subject's knowledge in pre-test (P<0.001). Conclusion: This study indicated that education program based on special traing considerably increase general awareness and attitde towards AIDS.

Background and Objective: Systemic lupus erythematosus (SLE) is an inflammatory multi-system disease with an unknown origin. In patients with lupus disease cardiovascular events is an important cause of mortality and morbidity. This study carried out to measurement of high sensitivity C –reactive protein (HsCRP) and homocysteine in patients with SLE and their relation with diseases activity and cardiovascular risk factors.

Materials and Methods: This case control study carried out on 60 patients (55 females and 5 males) with lupus disease which referred to Clinical Research Center of Rheumatology, Mashhad, Iran and 30 controls (26 females and 4 males) during 2007-08. Information of subjects were gathered using SLEDAI questionare. HsCRP and homocysteine of subjects were measured. The level of low density lipoprotein (LDL), Triglycerid, hypertension and Body mass index (BMI) was assessed. Systemic lupus erythematosus activity was assessed by using SLEDAI so that if the score was higher than 10, lupus was called as active disease.

Results: Mean age was 28.8±10.3 and 33.8±9.13 years in SLE and control groups respectively. The mean of HsCRP in SLE patients were 3±2.42 mg/dl versus in controls were 1.58±2.1. The serum level of homocysteine were 12.3±1.93 µmol/L and 24±8.13 µmol/L in SLE patients and controls (P<0.001). Mean disease activity was 15.37. There was no any associtation between homocysteine and HsCRP and disease activity. LDL, Triglycerid, hypertension had significant association with homocystein (P<0.05). BMI and Triglycerid had significant association with HsCRP (P<0.05).

Conclusion: This study showed that there is no linear significant corrolation between homocysteine, HsCRP and disease activity, but there is significant corrolation between increase of homocysteine and HsCRP and cardiovascular risk factors.

Background and Objective: Agricultural toxins including organochlorine and organophosphorus families cause damages in the various tissues in humans. Diazinon is a non-systemic organophosphate insecticide. This study was carried out to determine the effect of Diazinon on sex hormone, interferon gamma, interleukin-4 and 10 in male rats. Methods: In this experimental study 24 adult male Wistar rats were randomly allocated into four groups. Three experimental groups were received Diazinon 5 days per week for one month at 0.3, 3 and 30 mg/kg/bw intraperitoneally, while controls received nothing. Seven days after the last injection, blood samples were obtained and the serum testosterone, FSH, LH, interferon gamma, interleukin-4 and interleukin-10 were measured. Results: Serum level of Interleukin-10 significantly increased in experimental group (30 mg/kg/bw of Diazinon) compared to controls (P<0.05). Serum level of Interleukin-10 significantly decreased in 0.3 mg/kg/bw and 3mg/kg/bw of Diazinon groups compared to controls (P<0.05). Interleukin-4 level was only significant in the group receiving 30 mg/kg/bw of Diazinon (P<0.05). Reduction in interferon-gamma level was not significant between control and experimental groups. FSH significantly reduced in the three experimental groups in comparison with controls (P<0.05). Testosterone level was significantly increased in experimental groups compared to control (P<0.05). Conclusion: Diazinon increases interleukin-10 and testosterone and reduces FSH hormone in the rat.

Background and Objective: Behavioral disorders among children and adolescents are common and incapacitating which cause many problems for the families and the patient themselves and associated with high prevalence of negative social consequences. This study was done to evaluate the prevalence of psychiatric disorders among children and adolescents in Gorgon, north of Iran (2019).
Methods: This descriptive-analytical study was performed on 1025 children and adolescents aged 6-18 years in Gorgan, north of Iran (2019). Subjects were selected by Multistage Cluster Sampling. Digital version of K-SADS test was studied for 24 types of child and adolescent psychiatric disorders. Sampling was done by trained psychologists, among general population and by referring to the house of people. Psychiatric disorders included mood disorders, behavioral disorders, neurodevelopmental disorders, substance abuse disorders, and elimination disorders.
Results: The prevalence of psychiatric disorders among children and adolescents was 13.2%. This prevalence was 14.3 % and 12.1% in males and females, respectively. According to age groups, The prevalence of psychiatric disorders was common in 6 to 9 years olds with 17.8% which in comparison with other age groups was significant (P<0.05). Eliminatory disorder with 6.1% was the most common illness followed by behavior (6%), tension disorders (4.8%) and neurodevelopmental disorders (3.3%).
Conclusion: The prevalence of psychiatric disorders among children and adolescents in this area is in a median range compared to other domestic and overseas.

Background and Objective: Near to 30% of women experience some type of anxiety disorder in their life, which this anxiety occurs more often in pregnancy and after delivery. Maternal anxiety reduces secretion of oxytocin and lactation. On the other side, the level of maternal stress and anxiety increasingly increases the incidence of postpartum. This study was carried out to evaluate the prevalence of postpartum anxiety in Gorgan north of Iran during 2018.
Methods: This descriptive-analytical study was performed on 154 women between 15-45 years old and it has passed at least one week to maximum six weeks since their delivery whom referred to obstetrics clinic of Shahid Sayyad Shirazi hospital in Gorgan, North of Iran during 2018.

Background and Objective: Hemoptysis is defined as the expectoration of blood from the lower respiratory tract. Bronchiolitis, bronchogenic carcinoma, and bronchiectasis are the most common causes of hemoptysis in developed countries, while infections caused by Mycobacterium tuberculosis are the most common cause in endemic countries. This study was conducted to determine the frequency of causes of hemoptysis and some related factors.
Methods: This descriptive-analytical study was done on 68 patients (37 men and 31 women, average age 56.85±17.27 years) who were referred to the Shahid Sayyad Shirazi Hospital in Gorgan, north of Iran during 2014-16 with the complaint of hemoptysis. Demographic information, cause of hemoptysis and history of illness or drug abuse were extracted from the patients’ records.
Results: Based on the results, 42.6%, 45.6%, and 17.6% of the patients had a history of smoking, drug abuse, and diabetes, respectively. The most frequent causes of hemoptysis were bronchiectasis (25%), pneumonia (20.6%), tuberculosis, and lung cancer (16.4%). Gender was determined as an independent risk factor for hemoptysis (P<0.05). The most common causes of hemoptysis were bronchiectasis, lung cancer and pneumonia in men, and tuberculosis and bronchiectasis in women. Age, drug abuse, smoking, and diabetes had no significant association with the occurrence of hemoptysis.
Conclusion: Bronchiectasis, tuberculosis, and lung cancer are the main causes of hemoptysis, and gender is an independent risk factor for hemoptysis in the study area.
