The purpose of this epidemiological study was to use microscopical and molecular assays to detect coccidia prevalence and isolate species-specific Eimeria from sheep and goats kept in a common pan at high altitude in the central Zagros region. The central Zagros region is a mountainous, semi-humid and cold region with average rainfall which its southern counties are warmer than other districts. For these reasons, throughout the course of several seasons, 1200 fecal samples were obtained from three age groups (less than six months, six to twelve months, and more than six months). Oocytes were counted using saturated saline floating and modified MacMaster techniques and the physical characteristics of sporulated Eimeria oocytes were used to identify them. Finally, all positive fecal samples were sent to a PCR analysis, and coccidia infection was verified...

Procedure: Eighty composite soil and eight particles of Middle Chalcolithic Pottery were collected from Shahrekord district and the concentration of phosphorus, copper, molybdenum, lead and cobalt were measured by using atomic absorption spectrophotometry and inductively coupled plasma optical emission spectroscopy (ICP-OES), respectively. Statistical Analysis: For comparing the mineral concentration of soil and ceramics One Way Analysis of Variance (ANOVA) test were used at the significant level of p<0.05. Results: The average level of phosphorus, copper, molybdenum, lead and cobalt in the soil of Shahrekord district were 11.31, 12.04, 0.06, 0.79 and 0.126 mg/kg and their average in Middle Chalcolithic Potteries...

For this purpose, twenty, four-month pregnant ewes within the same age were used. During the 21 days leading up to birth, supplementation of selenium nanoparticles (Se NPs) with dosages of 0.05 and 0.10 mg/kg B.W. were respectively fed to treatment groups 1 and 2. And supplementation with sodium selenite with dosage of 0.1 mg/kg B.W. was fed to treatment group 3. At the same time the control group was fed distilled water in equal volume. The ewes were monitored under accurate laboratory and clinical examination until the time of delivery. Neonatal lamb serum thyroxin level was measured at the day zero (birth day) and also at the 7th day. The results indicated that serum thyroxin level of neonatal lambs of treated groups 1 and 3, decreased significantly at 7 days' age in compa...

The levels of calcium, phosphorus, magnesium, sodium, potassium, chloride, glucose, triglyceride, cholesterol, albumin, globulin and A/G ratio were assessed to find the correlation between the degree of hypocalcemia and other parameters. According to calcium concentration of milk fever cows (downers), five subgroups (); 5.1-6 as b); 6.1-7 as c); 7.1- 8 as d) and 8.1< as e)) were made and parameters were analyzed statistically as well. Results indicated that serum levels of calcium and phosphorus in downers were lower and magnesium concentration was significantly higher than that of the control group (P<0.05). A significant relationship was observed between level of daily phosphorus intake and k/Ca+Mg ratio and the incidence of milk fever (p<0.05). Calcium and glucose concentration of subgroup a) was significantly lower and higher th...

Heart rate, respiratory rate, body temperature, systolic and diastolic blood pressure, mean blood pressure and SPO were recorded at time 0 (before anesthesia induction) and at 2 15, 210 minutes after anesthesia initiation. Heart rate, ECG pattern, amplitude and configuration, segments and intervals were measured and compared between basal level (after nephrectomy and before anesthesia induction) and after halothane anesthesia. Results showed that respiratory rate significantly increased at 105 minutes after onset of anesthesia in comparison with the beginning of the experiment, while SPO 2 significantly reduced at 60, 90, 105, 120, 135, 150 and 165 minutes after onset of anesthesia (P&lt;0.05). The amplitude of P wave and QRS complex significantly decreased at 60 minutes after onset of anesthesia. Prolongation of QT interval occurred at 90 and 150 minutes after onset of anesthesia in comparison with time 0. ST segment significantly prolonged during anesthesia in comparison with time 0 (P&lt;0.05). Respiratory sinus arrhythmia was recognized in 7 cases previous to the beginning of the experiment. However, halothane anesthesia did not significantly affect them, except for 4 cases at induction time and 1 case at the time 0. Respiratory sinus arrhythmia reappeared in 2 cases at 20 minutes after onset of anesthesia. The occurrence of first degree AV block (1 case), sinoatrial block (1 case) and brady cardia (1 case) was recorded at 10 minutes after onset of anesthesia. Ultimately, it was concluded from the results that unilateral nephrectomized dogs could restore their circulatory system during halothane anesthesia, without any complication.
