The effect of zinc and iron supplementation on the status of iron and zinc in the primary schoolchildren

Ebrahim Fallahi, Mehrdad Seifi, Mohammad Ali Hasanvand Page 1

Background And Aim
The micronutrient deficiency is an important health problem around the world. Among the micronutrients, iron and zinc deficiencies are the most common. The aim of this study was to find the effects of iron and zinc supplementation, alone or combined, on iron and zinc status of the primary school children.
Methods
The study was a randomized double-blind clinical trial in which 81 primary schoolchildren of 11 years old were divided into 3 groups. Group 1 were supplemented with iron (20 mg/d), group 2 with zinc (20 mg/d) and group 3 with iron plus zinc (20 mg/d of each) for 4 months. At the beginning and at the end of this intervention, using cell counter, radioimmunoassay, and atomic absorption, hemoglobin plasma ferritin and serum zinc, the children, were measured. Data was analyzed using ANOVA, paired t test, Wilcoxon and Kruskal-Wallis tests.
Results
Our results showed that using either iron or zinc alone and using both of them together significantly increased the serum zinc level to 4.5±2.1, 4.5±2.7 and 3.6± micromole per liter, respectively. Among the 3 groups studied, zinc supplementation had the most benefit for the children who suffered from zinc deficiency (p<0.01). Using iron complementation alone, resulted in an increase in serum ferritin, while using zinc alone, led to a decrease in plasma ferritin (p<0.01). Both iron and zinc supplementation and the combination of them had no significant impact on blood hemoglobin.
Conclusion
Supplementation with either iron or zinc, would improve serum zinc and plasma ferritin.

The economic behavior of general hospitals of Iran

Aziz Rezapour, Mohammad Khalaj Page 11

Background And Aim
Economic analysis should be applied to hospitals for optimization. Therefore, this study was conducted to evaluate the economic behavior (production-cost) of general hospitals of Iran University of Medical Sciences from 1997 to 2004.
Methods
Data was collected using appropriate questionnaire and analyzed by t-test. In this research, Cobb-Douglas function and its T form was used for evaluation of production and cost, respectively.
Results
The marginal production of hospital labor for physician was 57, for nurse was 24, and for other personal was 0.04 of the patient admission. The marginal product of capital agent was 18 patient admissions. The personnel and non-personnel costs were 62 and 38 percent of the overall operatic costs respectively. Cost elasticity of overall expense to labor price, capital rate and production was 0.69, 0.48 and 0.32, respectively.
Conclusion
The hospitals can be on the decreasing part of LRAC (Long Run Average Cust) care and can decrease the unit cost of production with increasing economic agents.

The effect of submerged filter and ozone on biological treatment of wastewater

Abbas Jafari Dastenai, Mehdi Borghei, Mahmoud Borghei, Mehraban Sadeghi Page 17

Background And Aim
Wastewater treatment is carried out with various techniques. The conventional techniques are used for treatment of wastewater containing biologically active materials. The limitations of active-sludge method are production of sludge and failure of removal of carbohydrate and organic containing pollutants. Combination techniques are used successfully for treatment of industrial effluents including petrochemical, textural and similar wastewater. The aim of this study was to perform a combined biological system including fixed media reactor (Biofilm system) and ozonation and to compare the results with those of the conventional techniques.
Methods
This experimental-applicable study was performed to construct an experimental model using an aerated fixed film biological reactor with ozonation. At first, the imported and exported parameters of treatment plant of Shahrekord were tested. Then, following the set up of a pilot plant, the effluents of the plant using biological treatment with and without ozonation were measured.
Results
Our results showed that the mean of chemical oxygen demand (COD) in the pilot input was 541.2±171.3 mg/lit and in its output at the first and the second step was 226.6±194.4 and 64.1±26.6 mg/lit, respectively (p<0.05). The mean of biological oxygen demand (BOD) in the pilot input was 227.9±78.2 mg/lit and in its output at the first and second step was 106.6±64.5 and 55.8±30.4 mg/lit, respectively (p>0.05). The percentage of decolonization was 80 to 90 percent. The efficiency of ozone transfer to wastewater was 35 to 45 % and ozone consumption for each gram of COD removal was 0.35 to 0.75 milligram.
Conclusion
The results indicated that the combination of ozonation and fixed media biological reactors are strong tools for treatment of pollutants in wastewater. Removal of organic pollutants was considerably higher than that of the conventional methods and the sludge production was the lowest.

Evaluation of antibacterial activity of ethanol extracts of some medicinal plants against Listeria monocytogenes

Mohammad Jalali, Daryoush Abedi, Nasrollah Ghasemi Dehkordi, Amir Charmahali Page 25

Background And Aim
Listeria monocytogenes is a foodborne pathogen capable of causing outbreak or sporadic episodes in human. Most of the outbreak or sporadic episodes were in the last two decades and due to high rate of mortality, caused a great concern in food industries. There are various medicinal plants with the high performance of antibacterial activity in Iran. The present study investigated the anti-listerial activity of some of these palnts against two serotypes of foodborne L. monocytogenes.
Methods
The plants were used included: Thymus vulgaris L., Eucalyptus globulus Labill. Matricaria recutita L, Rosmarinus officinalis L and Saliva officinalis L. The plants were selected and identified by Pharmacognosy Department of Isfahan Faculty of Pharmacy. Extracts of the selected plants were prepared. Then antibacterial activity of these extracts was determined by disc diffusion method. The Minimal Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were also determined by the serial dilution method. Ampicillin (10 µg/disc) used in the test as standard.
Results
Only ethanolic extract of Eucalyptus showed antibacterial effects against L. monocytogenes in both disc diffusion and serial dilution method. MIC and MBC of this extract were 31. 25 µg/ml and 500 µg/ml, respectively. There was no significant difference between the sensitivity of the two serotypes. Extract of other plants did not show any antibacterial effects against L. monocytogenes.
Conclusion
Based on our results, only the extract of Eucalyptus showed antibacterial effects on both serotypes. Using other extraction methods and higher concentration of extracts may cause stronger antibacterial effect on L. monocytogenes.

The application level of the infection control methods in the operation wards of Shahrekord university hospitals compared to the standards in 2005

Kobra Noorian, Fereshte Aien, Masoume Delaram, Afsane Kazemian Page 34

Background And Aim
Nosocomial infection is an important health problem. The operation rooms of the hospitals are potentially favorite places for distribution of these diseases. It is now known that using standard control methods could prevent the infections. The aim of this study was to find the application level of these methods in Shahrekord universitiy hospitals and to compare them with the present standards methods.
Method
This descriptive analytical study was performed in three operation wards including 7 operation rooms. Data was collected using a questionnaire consisted of 54 questions about facilities and equipments, 8 questions about personnel practice related to infection control, 12 questions about individual hygiene and scrub methods, 8 questions about disinfection and sterilization and 7 questions about using preventive measures. The data was analyzed using t test.
Results
The findings showed that application of disinfecting and sterilizing methods (93.75%), individual health, scrub methods (79.2%), and the patient admission process (84%) were poor.
Conclusion
In conclusion, the operation wards have to be reviewed and supervised regularly for personnel, equipments, buildings, and training of the personnel to use disinfection control methods.
Keywords: Infection control standards, Operation room, Personnel
