The purpose of the present study was to evaluate effects of medetomidine on left ventricular outflow tract (LVOT) velocity in domestic short-haired cats. Eighteen healthy adult male domestic short-haired cats were used for this study. All animals were client-owned. Echocardiography machine with 7.50 MHz transducer was used. Specific veterinary two-dimensional and pulse-waved echocardiogram images in apical five chamber right parasternal view were obtained and blood velocity in LVOT was calculated. After baseline echocardiographic recordings, 0.04 mg kg-1 of medetomidine was intramuscularly administered to each animal and LVOT velocity was calculated after 15 (T15), 50 (T30) and 80 (T80) min following drug administration. The LVOT velocity values (mean ± SEM) of cats in baseline were 1.06 ± 0.04 m sec-1. There were significant differences between baseline and T15 and T30 regarding mean LVOT values. Age and weight had no significant effect on LVOT velocity values. The LVOT velocity values of T15, T50 and T80 were 0.77 ± 0.04, 0.80 ± 0.02 and 0.96±0.03 m sec-1, respectively. Our findings revealed significant decrease in mean LVOT velocity up to 50 min following medetomidine administration. The present study determined normal LVOT velocity range for a small population of cats before and after intra-muscular medetomidine administration.

Nosemosis is one of the most prevalent bee diseases in the world causing significant economic losses in the global bee-keeping industry. This cross-sectional study was conducted during April-September, 2016 to investigate the prevalence of nosemosis in different climatic regions of Iran. A total of 183 apiaries were selected based on cluster sampling and the climate of apiaries under study was classified using Domarten method. In each apiary, five percent of the colonies were randomly sampled. A total of 183 adult bee samples were taken and examined by microscopic and polymerase chain reaction (PCR) methods for the presence of Nosema infections. According to the results, infection caused by Nosema ceranae was observed in all regions under study. The prevalence of N. ceranae was 46.40% (42.70–50.10). However, infection with Nosema apis was not observed in the samples in either pure form or as associated infection. Based on the results of PCR, the prevalenceof N. ceranae was 53.80% (46.60– 61.00) in humid, 71.00% (53.70–77.50) in semi-humid, 68.10% (61.40–74.80) in very humid, 29.40% (22.70–36.10) in arid, 34.30% (27.40–41.20) in semi-arid and 24.00% (17.90–30.00) in Mediterranean climates. The prevalence of infection in different climatic zones of the country was found to have significant differences (p < 0.001). According to the findings, N. ceranae was the only Nosema species in honeybees with a broad geographical dispersion in Iran. It seems that climate can influence the prevalence of mentioned parasite.

The aim of this study was to determine the effects of intramuscular injection of medetomidine on intra-renal arteriesresistive and pulsatility indices by duplex Doppler ultrasonographyin clinically normal adult domestic shorthair cats. For this purpose, twenty-six neutered adult healthy domestic shorthair cats (13 females and 13 males) were evaluated. B-mode, color Doppler and pulsed wave Doppler ultrasonography of right and left kidneys were performed to record the resistive index (RI) and pulsatility index (PI) of intra-renal arteries. To minimize statistical errors, the mean RI and PI were determined for each kidney by averaging three waveforms from the intra-renal arteries. Twenty-four hr later, the cats were sedated by 0.04 mg kg-1 intramuscular administration of medetomidine. All the Doppler measurements were repeated 15 min after drug administration. Mean ± standard deviation )SD( of PI and RI of the intra-renal arteries before administration of intramuscular medetomidine were 1.03 ± 0.08 and 0.61 ± 0.02, respectively. Fifteen min after medetomidine administration, the mean ± SD of PI and RI values were 1.04 ± 0.08 and 0.61 ± 0.02, respectively. Significant differences were not detected in mean PI and RI values before and 15 min after drug administration. Our findings showed that intramuscular administration of medetomidine does not cause significant hemodynamic changes in the intra-renal arteries after 15 min.
