ABSTRACT
The aim of this study was to provide preliminary quantitative information on selenium and iodine status of sheep in Markazi province, Iran. Selenium and iodine status of grazing sheep were measured for 57 different flocks in 14 regions over one year. The districts were selected to represent major sheep growing areas in the province. Blood samples were collected from 2 to 3-year-old ewes during summer, autumn and winter. Samples were analyzed for blood glutathione peroxidase [GSHpx] activity and plasma inorganic iodine. There were significant differences between regions and seasonal differences in terms of blood GSHpx and plasma inorganic iodine concentration [P<0.01]. Low levels of GSHpx activity [<60 IU/gHb] and plasma inorganic iodine [<5micro g/dl] in some regions or some seasons indicated the need for dietary supplementation of these minerals
ABSTRACT
Halitosis is usually the result of vaporizing Sulfur Compounds [VSC] such as hydrogen sulfide and methyl mercaptan. The common solution to oral malodor problem is frequent rinsing with mouthwashes. The aim of this study was to compare the efficacy of three locally produced and commonly used mouthwashes with a zinc chloride 0.1% solution on in-vivo production of VSC. The selected mouthwashes under investigation were: [1] IR: an anti-plaque and tartar control mouthwash containing sodium benzoate and benzoic acid as the active ingredients; [2] NS: this mouthwash containing H[2]O[2] stabilized with Ag+ ions; and [3] CI: a herbal mouthwash. The positive and negative controls were zinc chloride [Zn] solution and distilled water [DW] respectively. The seven participants in the study were instructed to first rinse their mouth with 5 ml of 6 mM cysteine solution. They kept their mouth closed for 90 seconds, followed by taking baseline mouth air samples in order to be measured by a sulphide monitoring [VSC] device [Halimeter]. Immediately after taking baseline measurements, subjects rinsed 10 ml of each test mouthwashes and solutions for 1 min on different days in a random crossover design. VSC measurements were repeated every 20 minutes up to three hours. Statistical data analysis was conducted using SPSS software, One-way ANOVA and Post-hoc LSD tests. Data revealed that, there were significant differences between the tested agents only at 20, 40, 60, and 80 minutes after rinsing. The order of VSC inhibitory effect in the first hour was according to the following order: ZN>NS>DW>IR>CI while in the next two hours the order changed to: NS>DW>IR>ZN>CI. The results of this study showed that hydrogen peroxide mouthwash has the best anti-halitosis effect compared to others over the three hours of testing period, although the highest clinical effect was observed over the first 80 minutes of mouthwash administration

This study was conducted to determining the GPX, Hemoglobin concentration [Hb] and hematocrite percentage [Hct] in blood samples of young ewes were gathered at different places of Zagheh Salman pastures in Qom province. 15 blood samples were gathered through 8 flocks during autumn, winter and spring seasons randomly. At first the measures of GPX, Hb and Hct were determined and then GPX concentration in the basis of unit per gram of hemoglobin and unit per milliliter of hematocrite were calculated. Data were analyzed using SPSS software. Results showed that the ratios of GPX to hemoglobin concentration [GPX/Hb] and hematocrite percentage [GPX/Hct] were higher than their marginal levels significantly.There were significant differences between three seasons for hematocrite percentage and the ratios of GPX to hemoglobin [GPX/Hb] and hematocrite [GPX/Hct].The mean of hematocrite percentage had a maximum level in spring and minimum in winter. The ratios of GPX to hemoglobin and hematocrite had a maximum level in autumn and minimum in spring. The results of this research indicate that, despite of differences between flock and seasons all of flock had higher amounts of mentioned blood factors than their marginal levels and they had no deficiency aspects for these blood factors
