To evaluate method for monitoring anesthetic both with quantitative electroencephalography (q-EEG), we recorded processed EEG (raw EEG) and pain till 100 minutes in beagle dogs anesthetized for 60 minutes with propofol (n=5, PRO group), isoflurane (n=5, ISO group) and propofol-ketamine-fentanyl (n=5, PEK group). Raw EEG was converted into 95% spectral edge frequency (SEF) by fast Fourier transformation (FFT) method. We investigated anesthetic depth by comparing relationship (Pearson's correlation) between q-EEG (95% SEF) and pain score.

A 3-month-old, 2.8 kg, female Cocker spaniel was presented with chronic history of dysphagia since weaning. Video fluoroscopic examination revealed swallowing problems in the upper esophageal sphincters. It was diagnosed as cricopharyngeal achalasia. Cricopharyngeal and thyropharyngeal myectomy was performed. One day after surgical management, normal swallowing movement was observed in the video fluoroscopic examination of the dog. There was no evidence of recurrence for 15 months.

This case was found in Holstein cow suffering from dystocia. The twin calves in uterus were dead and removed by fetotomy. Gross anatomical analysis of thoracopagus siamese calf was carried out. Two normal heads were present on two necks, however, the twins were fused in the thoracic region. There were four forelimbs and an abnormal orientation of ribs. Two separate vertebral columns along the length of the animal ended with two tails. A single pericardium lay on the midline when opening the thorax.

This paper described the epidemiological characteristics of 2002 outbreak of classical swine fever (CSF) in Korea. A total of thirteen CSF-infected farms could be classified into two clusters according to the location and time of outbreak. Two farms located in the same county of Gangwon province and 11 farms located in several different districts of Incheon metropolitan/Gyeonggi province were identified as CSF-infected from April 16 to 30 and from October 7 to December 21 in December 21 in 2002, respectively.

Shiga toxin (stx) producing Escherichia coli (STEC) causes various clinical signs in animal and himan. In this study, 255 fecal samples from samples from calves showing diarrhea were collected from cattle farms in Chonnam province during the period from January 2005 to July 2005. Twenty six STEC (10%) were isolated from 255 fecal samples by PCR. The isolates displayed three different stx combinations (stx1[69%], stx1 and stx2 [15%], and stx2 [38%]). The isolates were further studied for virulence associated genes and antimicrobial resistance to define the virulence properties.

This paper describes a naturally occurring case of meningoencephalitis associated with Listeria monocytogenes in a 4 month-old Korean native goat. The goat was raised in a herd consisting of seventy goats, and fed on straw and leftover vegetables including onions, cauliflower, and bean sprouts. The clinical symptoms of the goat were depression, inappetence, anorexia, circling, and recumbency before death. No conspicuous gross lesions were found except consolidation of the lung.

To determine the effects of β-carotene on the control of mastitis in dairy cows during the dry period, 38 dairy cows (18 mastitic cows and 20 healthy cows) were administered with 5ml of β-carotene (30 mg/ml) intramuscularly twice (4 week intervals). Blood samples were taken from the cows before the injection and two weeks after the second injection, respectively, and were measured for the cows before the lymphocyte subpopulations and lymphocyte proliferation responses.

A stochastic simulation model incorporated with Reed-Frost approach was derived for evaluating diagnostic performance of a test used for a screening program of an infectious disease. The Reed-Frost model was used to characterize the within-herd spread of the disease using a hypothetical example. Specifically, simulation model was aimed to estimate the number infected animals in an infected herd, in which imperfect serologic tests are performed on samples taken from herds and to illustrate better interpreting survey results at herd-level when uncertainty inevitably exists.

Objective-To use in vitro assays to evaluate the effects of a novel immunosuppressive agent, FTY720, on biological functions (migration, phagocytosis, and production of reactive-oxygen species ROS) of feline peripheral neutrophils and determine the cytotoxic effects of FTY720 on feline peripheral neutrophils. Sample Population-Peripheral neutrophils obtained from 8 healthy cats. Procedure-Peripheral neutrophils were isolated from blood samples obtained from the 8 cats and exposed to the phosphorylated form of FTY720 (FTY720-P). A fluorescence-based in vitro evaluation of migration was performed. Phagocytosis of microbes and production of ROS were evaluated by use of a 2-color flow cytometry system. Samples of whole blood obtained from the cats were incubated with various concentrations of FTY720-P, fluorescein-labeled Staphylococcus aureus, and dihydroethidium. Cytotoxic effects were evaluated by use of propidium iodide staining. Results-Addition of FTY720-P caused a slight nonsignificant decrease in phagocytosis and production of ROS by feline peripheral neutrophils. Migration activity of feline peripheral neutrophils was significantly increased by the addition of FTY720-P. Addition of FTY720-P at concentrations considered for clinical use did not increase the death rate of feline peripheral neutrophils. Conclusions and Clinical Relevance-FTY720 does not inhibit critical functions of feline peripheral neutrophils in vitro.

Objective-To determine gene expression of selected molecular markers (tumor necrosis factor TNF-alpha, interleukin IL-1beta, IL-6, IL-8, IL-10, procalcitonin PCT, and transforming growth factor TGF-beta) in the blood of healthy and sick foals. Animals-28 sick foals without sepsis, 21 foals with sepsis, and 21 healthy foals. Procedures-Total RNA was extracted from blood samples and converted into complementary DNA (cDNA). Gene expression was measured for the molecular markers by use of real-time PCR assay, and final quantitation was performed with the comparative threshold cycle method. Results-Samples from all foals yielded transcription for all markers. Expression of TNF-alpha and TGF-beta was significantly lower and that of IL-8 significantly greater in the sick-nonseptic and septic groups, compared with the healthy group. No significant difference in expression of IL-1beta, IL-6, and PCT was found between the healthy group and the 2 sick groups. Expression of IL-10 was significantly greater in nonsurvivors, compared with survivors. Conclusions and Clinical Relevance-The cytokine profile in foals with sepsis may suggest an immunosuppressive state. Expression of IL-10 may be a marker for identification of foals with a guarded prognosis.
