Background & aim: Work is an important component of QOL therefore work-related factors could be a significant predictor in this respect.The current study was aimed to asses QOL and its association with socio-demographic, health and work-related factors in two factories in Yasuj, Iran. Methods: In the present cross-sectional study, participants were 280 workers of two factories. The Persian version of World Health Organization Quality of Life-Brief (WHOQOL-BREF) was used to assess the QOL. A questionnaire was developed to assess the socio-demographic, health and work-related factors. Data were analyzed using descriptive statistics. Results: The present study revealed that the means (SD) of physical health, psychological health, social relationships, and environment domains of QOL were 13.2 (2.7), 13.3 (2.6), 14.2 (3.5) and 12.6 (2.5), respectively. A multiple linear regression demonstrated that the types of job, exercise activity, working schedule, sleep quality, smoking, and conflict between work and social life were associated with physical health domain whereas, working schedule, marital status, working demand, sleep quality, BMI, and conflict between work and individual life were significantly associated with psychological health domain. Working schedule, working demand, sleep quality, conflict between work and individual life were significantly associated with social relationship domain however, working demand, working schedule, smoking, sleep quality, working hour, job satisfaction, marital status and exercise activity were significantly associated with environment domain. Conclusion: To improve workers' QOL, the intervention programs should focus on improving work environment, working schedule, occupational training and restricting working hours.

Background & Aim: Diabetes mellitus is the most common endocrine disorder in the world which causes ovarian dysfunction. The aim of this study was to evaluate the effect of omelette powder on ovarian tissue changes in diabetic rats using a high-fat diet based on streptozotocin HFD / STZ.
 
Methods: In this experimental study, 25 female rats (Wistar rats) were divided into 5 groups of 5. The first group, as the control group, the second group was received high-fat diet (HFD) (fat 60% + 25% carbohydrate + protein 15%), followed by STZ (35 mg / kg) intravenous 4 weeks. the third group received diazepam (200 mg / kg), the fourth group received metformin (200 mg / kg), the fifth group as sham or the control group of healthy rats (200 mg / kg) received only Abelmoschus esculentus powder. After 4 weeks of treatment the animals were euthanized body weight, ovary weight and insulin resistance markers (levels of insulin, glucose and HOMA-IR) were measured. From the right ovary sections  of 5 to 6 micrometers in diameter were prepared, stained and then studied.Data were analyzed using ANOVA and LSD tests.
 
Results: Hyperglycemia, insulin resistance and reduced body weight of diabetic rats were improved after administration of Abelmoscus esculentus powder in duration of 4 weeks. This effect was relatively similar to metformin. Abelmoscus esculentus powder was caused a significant increase in primordial, primary and graffian follicles (P<0.05) and early corpus luteum. A significant reduction were seen also in the preantral and antral follicle atresia (P<0.05) and old corpus luteum in ovary of diabetic rats.
 
Conclusion: The results of this study showed that Abelmoscus esculentus powder with its antioxidant activity and other properties has a correlation function on hyperglycemia and suitable intermediates for the improvement of ovarian disorders in diabetic rats.
