The aims of this study were to determine vertebral heart size (VHS) in stray cats and to compare different radiographic views. This study was performed on 50 adult stray cats. All cats were short-haired and non-obese and were considered to be healthy based on physical examination and electrocardiography. Left and right lateral, dorsoventral and ventrodorsal radiographs were taken. The long and short axes of the heart were measured in millimetres. The thoracic vertebral length spanned by each dimension was measured caudally from the fourth thoracic vertebra. Mean+/-SD and the correlation coefficient between the measurements were calculated with standard statistical software. The sum of the long and short axes of the heart expressed as VHS was 7.3+/-0.49 vertebrae in right lateral, 7.3+/-0.55 vertebrae in left lateral, 7.5+/-0.68 vertebrae in dorsoventral and 7.5+/-0.53 vertebrae in ventrodorsal. The differences between right and left lateral as well as dorsoventral and ventrodorsal views were not significant (P>0.05). Absolute measurements and vertebral heart scale values were slightly smaller than those reported in the literature for mixed population of cats. It is, therefore, important to take the breed in to account.  相似文献

ObjectiveTo evaluate the cardiopulmonary effects of anaesthesia induced and maintained with propofol in acepromazine pre-medicated donkeys.Study designProspective experimental study.AnimalsSix healthy male donkeys weighing 78–144 kg.MethodsDonkeys were pre-medicated with intravenous (IV) acepromazine (0.04 mg kg−1). Ten minutes later, anaesthesia was induced with IV propofol (2 mg kg−1) and anaesthesia maintained by continuous IV infusion of the propofol (0.2 mg kg−1 minute−1) for 30 minutes. Baseline measurements of physiological parameters, and arterial blood samples were taken before the acepromazine administration, then 5, 15, 30, 45, and 60 minutes after the induction of anaesthesia. Changes from baseline were analysed by anova for repeated measures.ResultsWhen compared with baseline (standing) values, during anaesthesia heart rate increased throughout: significant at 5 (p = 0.001) and 15 (p = 0.015) minutes. Mean arterial blood pressure increased significantly only at 15 minutes (p < 0.001). Respiratory rate and arterial pH did not change significantly. PaO2 was lower throughout anaethesia, but this only reached significance at 15 minutes (p = 0.041). PaCO2 was statistically (but not clinically) significantly reduced at the times of 30 (p = 0.02), 45 (p = 0.01) and 60 (p = 0.04). Rectal temperature decreased significantly at all times of the study.Conclusions and clinical relevanceAdministration of propofol by the continuous infusion rate for the maintenance of anaesthesia resulted in stable cardiopulmonary effects and could prove to be clinically useful in donkeys.  相似文献

Common carp were exposed to two routine therapeutic concentrations of copper sulfate (10 mg/l in 1 h and 1 mg/l in 24 h). At different times after the copper sulfate bath (1, 2, 3, 7, 14 and 30 days), the copper concentrations in liver and muscle of carp was determined by means of an atomic absorption spectrophotometer. The results showed that the concentration of copper is significantly higher in liver than in muscle in all groups (p < 0.01). Concentrations of copper in liver and muscle in long-term bath groups were also significantly higher than short-term bath (p < 0.05). The concentration of copper in the livers of the control group was 174.2 ± 5.2 mg/kg. This value was significantly lower than the experimental groups even at 30 days after long-term baths (p < 0.01) but was not significantly higher than short-term bath (p > 0.05). The concentration of copper in the muscle of the control group was 22 ± 3.2 mg/kg, this value was significantly lower than for the short-term and long-term groups (p < 0.01). In livers, copper concentrations in short and long-term bath increased to an average of 281.6 ± 17.1 and 397.8 ± 31.2 mg/kg, respectively, by day 1 of treatment and then significantly declined to 189.8 ± 9.6 and 203.5 ± 8.9 mg/kg by 30 days post-treatment (p < 0.05). In muscles, copper concentrations in short-term bath increased from 39.1 ± 4.7 in first day of treatment to 50.8 ± 6.5 mg/kg in 30th day, but not significantly (p > 0.05), while in long-term bath it decreased significantly from 127 ± 13.6 to 43.2 ± 2.7 mg/kg (p < 0.05). This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

For the past 2 decades, a great deal of research has been done in fish technology, particularly in the area of mechanically deboned minced fish. Minced fish is the edible muscle flesh of fish that has been mechanically separated from the bones and skin. Ideally, the product is prepared from a high quality fish and resembles hamburger meat. In its final form, minced fish is used either as an ingredient or as an extender in seafood or in food products that require further processing. On the basis of technological advancements, the National Marine Fisheries Service of the U.S. Department of Commerce and the National Fisheries Institute jointly petitioned the U.S. Department of Agriculture in 1980 to add minced fish at a level of 15% in the meat formulation of frankfurters. This paper explores certain aspects of processing, production, acceptance, and hazard assessment of minced fish ingredients as possible protein supplements in meat and poultry food products relative to this request.  相似文献

Lysiphlebus fabarum Marshall is the main parasitoid of the black bean aphid, Aphis fabae Scopoli. Lethal and sublethal effects of insecticides, thiacloprid+deltamethrin, pirimicarb and pymetrozine were evaluated on the parasitoid under laboratory conditions. One-day-old mummies were exposed to the recommended field concentration of either insecticides via dipping method. Adult emergences were reduced by 82.67, 19.98 and 10.67 % for thiacloprid+deltamethrin, pirimicarb and pymetrozine treatments, respectively. Thiacloprid+deltamethrin had the most adverse effect on the fecundity of the emerged females, while pirimicarb and pymetrozine did not have such effects. According to International organization for biological control (IOBC) insecticide toxicity classification, thiacloprid+deltamethrin resulted to be moderately harmful (E = 97.39%), whereas pirimicarb (E = 15.78%) and pymetrozine (E = 5.15%) were harmless. Thiacloprid+deltamethrin negatively affected five of the estimated demographic parameters (GRR, R 0 , r m , λ and T ). Pirimicarb negatively affected GRR, R 0 and T, while it had no adverse effects on r m and λ. None of the studied demographic parameters were affected by pymetrozine. Our results suggest that pirimicarb and pymetrozine can be considered as safe for L. fabarum, but that thiacloprid+deltamethrin can have serious detrimental of this parasitoid in the field.  相似文献

The objective of the present study was to describe the arthroscopic anatomy of the bovine fetlock joint using one palmar/plantar and three dorsal joint approaches. A comparative anatomic, ultrasonographic and arthroscopic study using 20 cadaveric feet from 13 non-lame adult dairy cows was performed. Arthroscopy was accomplished using a rigid arthroscope to view the synovial cavities with their synovial villi and parts of the following structures: the distal ends of the metacarpal/metatarsal III/IV bones with their trochleae and sagittal ridges, synovial grooves, the articular surfaces of the proximal sesamoid bones, the proximal aspects of the first phalanges, the lateral and medial collateral ligaments, the suspensory ligament and the interdigital ligaments as parts of the interosseus muscle, the cruciate sesamoidean ligaments, the communication site between the lateral and medial pouch in the palmar/plantar area, and dorsally the septum between the lateral and the medial pouch. The technique allowed a good overall view of most relevant structures in the sound cadaver joint. Further investigations are warranted to evaluate the diagnostic, therapeutic and prognostic applications of these techniques in the treatment of septic arthritis.  相似文献

Root water uptake is a component of water balance that has not been clearly understood. This study was carried out in a completely randomized design with three replications under the greenhouse condition at Shahrekord University, Shahrekord, Iran. In this study, the root water uptake (RWU) by pepper plant under various irrigation water levels was investigated. Irrigation treatments included control (full irrigation level, FI) and three deficit irrigation levels, 80%, 60% and 40% of the plant's water requirement called DI80, DI60 and DI40, respectively. A no-plant cover treatment with three replications was also used to measure evaporation from the soil surface. Daily measurements of volumetric soil moisture (VSM) were made at 10 cm intervals of the soil column. The differences between the measured VSM and the VSM in the next day, and evaporation rate at the soil surface at the same layer of the no-plant cover treatment were calculated and, eventually, the RWU in each layer per day was estimated. The results showed that the maximum and minimum RWUs were found in the FI and DI40 treatments, respectively. The averages of root water uptakes in the DI80, DI60, and DI40 treatments were reduced by 17.08%, 48.72% and 68.25%, respectively. Furthermore, in the DI80 treatment, the reduced rate of water uptake was less than the reduced rate of water applied to the plants.  相似文献
