Background: Lavandula officinalis has anti-anxiety and sedative properties. In the present study, the antidepressant effect of aqueous and hydroalcoholic extracts of Lavandula officinalis in forced swim test (FST) and tail suspension test (TST) in male mice was investigated.

Materials and Methods: In this experimental study, 72 male mice were randomly divided into 9 groups of 8: Negative and positive control groups received normal saline (10 ml/kg), fluoxetine (20mg/kg) and imipramine (30mg/kg) respectively and treatment groups received extracts of Lavandula officinalis (100,200 and 400 mg/kg). Immobility, swimming and climbing behaviors were recorded during 6-min.

Results: Lavandula officinalis extracts (except the aqueous extract at a dose of 100 in FST) compared to control group significantly and dose dependently reduced the duration of immobility time a both of tests (p<0.001).Also, these extracts (except the aqueous extract at a dose of 100 in FST) significantly and dose dependably increased swimming time (p<0.001) without significant change of climbing time.

Conclusion: Lavandula officinalis has considerable antidepressant-like effect and their effect similar to fluoxetine.

Introduction: Paints are composed of extensive variety of hazardous substances, such as organic solvents and heavy metals. Occupational exposure to paint increases oxidative stress, hematological disorders, and DNA injury. This study was performed to explore the beneficial effects of Selvit on the paint workers by measuring total antioxidant capacity, lipid peroxidation, and blood parameters as main oxidative stress biomarkers.

Materials and Methods: This clinical trial study was conducted on 25 male workers who worked in the paint factory. Serum markers such as total antioxidant capacity (TAC), lipid peroxidation (LPO) and also hematological parameters were measured before and after using Selvit (14 days). SPSS software was used for data analyses and paired t-test and Pearson correlation analysis were applied.

Results: Results showed that after using the Selvit, an increase in TAC and a decrease in LPO were observed but they were not significant. Also, aspartate transaninase significantly decreased after using Selvit and high density lipoprotein significantly increased.

Conclusion: Selvit have beneficial effect on hematological parameters due to its antioxidant capacity.

Moreover 4 sub-categories (improve of index of public health and care, health folder, insurance for rural, low referral to expert of physican), were created.

Conclusion: Based on the results the use of electronic folders instead of traditional folder and accelerate to acsess of information patient for promotion of care and finally delivery some facilitate for health team worker recommended.

Background: The current paper set out to investigate the level of asbestos fiber and asbestos body in sputum and assayed of haematological factors, liver enzymes and pulmonary function test in asbestos exposed group.

Materials and Methods: An analytical cross-sectional study was conducted with a total number of 100 subjects. The case group included 50 male workers with the age range of 25-60 who had at least worked for five years in the asbestos-cement factory. Control subjects consisted of 50 people who had no history of occupational exposure to asbestos. Lung function tests were measured with a portable calibrated vitalograph-PFT spirometer. liver enzymes were assayed with Pars Azmoon kits. Counts of red blood cells and white blood cells were assayed with a cell counter. We used light polarizan microscope to study the level of asbestos fiber and asbestos body in sputum.

Results: Asbestos fiber observed in sputum sample of workers and type of asbestos fiber is chrysotile. Asbestos bodies were found in only 10% of the workers. Decrease (but not significant) in lung function factors (FVC, FEV1, FVC/FEV1) had been seen in the workers in compare with control group. WBC, Eosinophil, neutrophil, lymphocyte, monocyte and liver enzymes levels were significantly higher (but in normal range) in workers as compared with the control group.

Conclusion: Presence of asbestos fiber and asbestos body in workers sputum samples showed workers exposure to asbestos and reduced level (insignificant) of lung function factors and increased level of leukocyte may be indicated pulmonary inflammation. These results also suggested that occupational exposure to asbestos dust may perturb liver mal function parameters

Background: Spinal anesthesia is an efficient method of providing intra operative analgesia and a safe alternative to general analgesia in many cesarean patients. Despite its advantages, SA is not free from adverse effects, which include unwanted cardiovascular events, in most cases: hypotension and bradycardia. Ondansetron is a 5HT3 receptor antagonist, with known efficacy on preventing nausea and vomiting. Maybe ondansetron given intravenously attenuates the fall of blood pressure and heart rate, by 5HT3 blocking in vagal nerve endings and effect on BJR.(Bezold jarish Reflex).

Materials and Methods: In this clinical trial 102 healthy pregnant women that were candidate for elective cesarean in hamedan fatemieh hospital during 3 months in 1390, studied. They were randomized into 2 groups: the ondansetron group, n= (51) received (4miligram) ondansetron intravenously before performing spinal anesthesia, and placebo group n= (51): received 2cc sterile water before spinal anesthesia. Spinal anesthesia was performed with hyperbaric bupivacaine (0.5%) 10 mg and sufentanil (5 µg) BP and HR were measured and recorded before and after anesthesia immediately. If hypotension happened, ephedrine 5- 10mg injected. Itching and nausea recorded every 10 min during operation by observation and question.

Results: There were no significant differences in SBP, DBP, MAP, HR and itching in both groups. Nausea and vomiting ,and mean consumed ephedrine was siginificantly different in both groups.(p=0.001, p=0.009).

Conclusion: Ondansetron given intravenously with antiemetic dose (4miligram), decreases mean consumed ephedrine and nausea and vomiting after spinal anesthesia, but doesn't have an influence on BP, HP and pruritus

Background: Nickel and chromium are heavy metals whieh after arriving in biological systems can produce highly reactive free radicals in the body and interact with macromolecules cause damage to them. The purpose of this study, the effect of bilberry and cinnamon extract on blood biochemical factors in workers exposed to nickel and chromium.

Materials and Methods: In this clinical trial, 99 workers were divided into 3 groups: group 1 (control), group 2 workers, welders exposed to nickel and chromium without extract (G) and group 3 workers, welders exposed to nickel and chromium with extracts (B). First biochemical parameters were measured in blood serum. Then the group 3, 2 times a day for four weeks, billberry juice and tea - Cinnamon received. Finally, Biochemical parameters in blood were measured and compared. SPSS software and descriptive statistics (mean±SD), T- independent and one-way ANOVA test were used to analyze the data.

Results: Between group Variance in some biochemical variables between the three groups, control, G and B showed statistically significant differences (p<0.05). Within-group variance was significant in some variables.

Conclusion: After consumption of billberry juice and tea-cinnamon positive changes in biochemical parameters in workers who are exposed to the toxic effects of nickel and chromium was obtained.

Abstract

Background: Operating room personnel are subject to occupational hazards which could lead to an increase in free radicals and develop various diseases. The aim of the present study was to determine the effect of consuming green tea on the improvement of the blood oxidative biomarkers in operating room personnel who are exposed to anesthetic gases.

Materials and Methods: This study was a before-after clinical trial which was conducted on 24 operating room personnel. They were invited to consume 4 cups of a green tea beverage, prepared from 3 g of green tea leaves in 300 mL of boiled water (at 80˚ C), daily for 8 weeks. Then, Myeloperoxidase (MPO), DNA damage, Glutathione Peroxidase (GPx), and Superoxide Dismutase (SOD) in the plasma were measured in order to evaluate the level of oxidative stress biomarkers before and after consuming green tea.

Results: Green tea consumption by operating room personnel brought about a significant increase in glutathione peroxidase and superoxide dismutase and a considerable decrease in myeloperoxidase and DNA damage.

Conclusion: According to the results of this study, green tea consumption as an antioxidant supplement by operating room personnel, who are regularly exposed to anesthetic gases, can minimize oxidative stress and DNA damage considerably. Thus, it is advisable for operating room personnel to consume green tea as a natural antioxidant supplement.
