ABSTRACT
Because of a paucity of information on the effect of Satureja khuzistanica in male chickens, this study was undertaken to determine the influence of dietary S. khuzistanica powder [SKP] on seminal characteristics and testes thiobarbituric acid reactive substances [TBARS] content in Iranian native breeder rooster. Thirty-six 40-week-old roosters were randomly allotted to 3 equal groups and received either a basal diet without SKP [T1 or control], or a diet containing 20 g/kg [T2] and 40 g/kg [T3] of SKP for 8- week-long experimental period. Semen samples were obtained weekly by abdominal massage to evaluate the seminal characteristics. At the end of the eighth week 18 birds [6 birds per each group] were randomly slaughtered, and sample was taken from right testes for TBARS evaluation. Administration of SKP improved all semen traits, except for sperm concentration. Likewise, TBARS content in SKP treatments did not significantly differ from the control [P>0.05]. Seminal volume, live sperm percentage and plasma membrane integrity percentage in SKP-treated groups were higher than the control. Conversely, abnormal sperm percentages reduced in SKP-treated groups [P<0.05]. Plasma membrane integrity in experimental treatments was significantly higher than the control in 2nd, 3rd and 7th weeks. However, at 6th and 8th weeks only T3 treatment was significantly different from the control. Notably, there was an increase in total sperm concentration in SKP-treated groups in compared to the control birds. In conclusion, this study indicated that addition of SKP in rooster diet improves sperm quality and also reduces their sperm membrane lipid peroxidation, which may lead to higher fertilization rate.
ABSTRACT
The main signs of cardiac disease [particularly the coronary disease] was chest pain and the shortness of breath. ETT is a prognostic and diagnostic tool for assessing the ischemic heart patients. The aim of present study was to determine the results of applicating ETT for patients with typical and atypical chest pain complaints referring to the Mazandaran Cardiac Center 2007. This descriptive study was conducted on 500 patients with typical and non Typical pain referring to the heart centers of Mazandaran province. After the interview, examination and laboratory tests, attended by the researcher and cardiologist, the patients under went ETT [Exercise Tolerance Test] with Tread mill according to Bruce protocol [Bruce Protocol] in four steps. The present study showed the positive effect of exercise test in 80[16%] of cases. The positive test results of exercise test in the cases with typical heart pain was 25 times more than the cases with atypical heart pain. 43[53.75%] of the cases with positive test were male the majority of whom were [41caseses,51.25%] in age range of 51-65 years. 12.5% of cases with positive test and also 78.6% with negative test had atypical pain. getting serious signs and symptoms of various disease serious [especially of the typical and atypical chest pain] is among the main educational priorities for the prevention of cardiac infarction
ABSTRACT
lack of information about anaesthisia and fear of post operation contiousness, pain, nausea and vomiting increases the patientsH anxiety. There are various reports about patiensH desire for preoperation information in Iran and other countries. However, there is no study related to anaesthesiologistsH view about patientsH needs before anaesthesia and operation in the literature. This descriptive [cross- sectional] study was done in 2005 on 110 anaesthesiologists working in hospitals of Mazandaran province. Questionnaire containing 4 questions about demographic and 18 questions related to anaesthesia was prepared. Attitude of the anaesthesiologists was divided into 5 categories based on Likert rating scale as follows: completely agreed, agreed, partially agreed, not agreed, completely not agreed. Chi-square test was used for the statistical analysis of the data. Results of this study showed that the most positive attitude of anaesthesiologists about patient teaching was related to the proper explanation about duration of N.P.O before operation [%97.3].%52.7 of anaes the siologists were against giving explanation of the duration of N.P.O and post operation possible problems. In this regard no significant difference was observed between educational and non educational hospitals [P<0.018]. No significant difference in terms of attitude was observed between anaesthesiologists at different level of education [P<0.07]. Considering the positive attitude of the anaesthesiologists towards education and preoperation of the patients, it is recommended that such education be implemented and the patients be charged for preoperation consultation in order to give explanation about anaesthesia at proper time, when needed
