Abstract
Background: Hospital as the gravitational center of the health and treatment system and an open system involving complex processes and various (qualitative and quantitative) resources, needs an effective leadership style and an approperiate strategy to solve the organizational disagreements and conflicts in order to achieve its basic objectives. The object of this research is to study the relationship between leadership style and conflict management among the managers of the hospitals, which sponsord by Lorestan university of Medical sciences during the year 2004.
Materials and Methods: This research is a descriptive – analytical study. The necessary information was gathered by three different questionnaires (personal information, leadership style using Fiedler’s LPC method and conflict management), and also by interviewing the subjects. The collected data were analyzed using statistical software. The research sample consisted of 177 managers from 13 hospitals, which were sponsored by Lorestan university of medical sciences.
Results: The findings demonstrated that 54.2 percent of the subjects had a duty-oriented leadership style, 35.6 percent had a relationship – oriented leadership style, and 10.2 percent of the subjects had an independent – social leadership style. Considering conflict management strategies, 49.7 percent showed a non – confrontational strategy, 44.6 percent demonstrated a control-oriented strategy and 5.7 percent had a problem- solving strategy. The subject’s leadership style had a significant statistical relationship with their job experience (p=0.043). Also, there was a significant statistical relationship between conflict management strategies and the sex of the subjects (p= 0.036). Age of the subjects and their control-oriented strategy also demonstrated a significant statistical relationship(p=0.01).
Conclusion: Determining the leadership and management styles and identifying the methods of dealing with disagreements and conflicts in hospitals is crucial. Since some of the factors involved in leadership style and conflict management have been studied in this research, it is suggested that the effect of other factors such as organizational culture , social culture , race , personality , etc. on the leadership style of people be studied more comprehensively.

Abstract
Background: Carotenoids comprise a significant group of natural pigments produced by plants and some microorganisms such as fungi. These useful pigments have beneficial properties, including the antioxidant property. The goal of the present project is to produce carotenoids by Fusarium oxysporum fungus and its effect on liver enzymes in male mice.
Materials and Methods: Fusarium exosporium fungus was cultured in a suburodecroserase agar medium. In this study, carotenoids were first extracted by the solvent method under optimal conditions of the solvent mixture of acetone, methanol and petroleum ether for 24 hours. The drying process of pigment extraction was carried out using Davis method. In the next stage, 24 male mice were randolmly divided into three groups of eight mice. Two treatment groups received carotenoid via intraperitoneal injection (16 and 32 mg / kg), and the last group received this product in the control group. 0.2 mL was of physiologic serum was injected intraperitoneally. Subsequently, heart blood was collected from the rats and liver factors were evaluated. The results were analyzed using SPSS 21 software and all the data were compared using the ANOVA method.
Results: The results showed that carotenoid extracted from Fusarium oxysporum fungus altered the activity of liver enzymes.The concentration of SGPT and ALP enzymes significantly decreased in the injectable group (32 mg / kg).
Conclusion: The antioxidant properties of carotenoids in thick doses reduced the activity of liver enzymes.This function is probably due to the antioxidant properties of carotenoids and the oxidative stress control and radical trapping of free radicals. Given the physiological similarities between the human body and mice, the use of high doses of carotenoids in food industries is recommended.
