This work described 3 infection cases caused by Rhodococcus equi in foals between 3 and 5 months of age. The disease histories were not fully taken from local veterinarians. At least 1 sick foal has been treated with cephalothins followed by penicillins during approximately 1 week, but died without effectiveness and other foals rearing with the animal have been suffering from severe pneumonia which show high fever, laboring respiration, cough and/or nasal discharge. There were many abscessations into lungs of 2 foals in postmortem examination and another 1 sample was pus collected from abscess around the shoulder, indicating the osteomyelitis. Those bacteria were grampositive coryneform and were identified as a R. equi by a polymerase chain reaction (PCR) using primers for R. equi-specific vapA gene. The pathogens were usually resistant to penicillin, ampicillin, amoxycillin/clavulanic acid, cefazolin, clindamycin, sulfamethoxazol/trimethoprim, kanamycin, and tetracycline, while were sensitive to ciprofloxacin, norfloxacin, orfloxacin, gentamicin, erythromycin, neomycin, and vancomycin. Some more foals with respiratory symptoms in 1 horse farm were treated by orally administration with erythromycin during 2 weeks. Because the combination of erythromycin and rifampin has recommended as the treatment for R. equi infections in foals, the local equine veterinarian can choose those antibiotics for the treatment of this disease in future. However, another antimicrobial agent may be necessary if R. equi resistant to both agents is isolated.

To investigate the effects of seeding during freezing procedure on post-thaw viability, motility, and acrosome integrity of boar spermatozoa, semen from 5 Yorkshire boars were collected for this experiment. Raw semen were diluted with Merck I, subsequently added with cooling diluent containing lactose and egg yolk and with freezing diluent containing glycerol. The diluted semen were frozen on the rack in the styrofoam box filled with liquid nitrogen at the distance of 5 cm or I cm above LN2 level. Seeding was performed to only a group of straws frozen at 5 cm away on the surface of LN2. The frozen semen were thawed in $50^{\circ}C$C water and the viability and local motility were analyzed by sperm analysis imaging system. A part of thawed semen was taken for the examination of morphology of apical ridge of the acrosome to compare with the effect of seeding between the seeding-treated and non treated groups. I. Post-thaw viability was considerably higher in seeding-treated sperm than non-seeding group (p<0.01), however, no difference of local motility was obtained among the groups. 2. At three hours after thawing, viability was also higher in seeding-treated group than non-treated group (p<0.05), along with no difference of motility among the groups. 3. Higher normal acrosome integrity was obtained in the seeding-treated sperm than non-treated groups (p<0.01). 4. Between non-seeded groups, higher normal acrosome integrity was obtained in the sperm group frozen at 5cm upper on the surface of LN2 than that frozen at 1cm away (p<0.01). These results indicated that seeding treatment during freezing boar spermatozoa was beneficial to post-thaw viability and normal acrosome integrity.

To evaluate butorphanol and tramadol as adjuvants to lidocaine in dogs undergoing mandibular nerve block. Fifteen beagles were allocated to groups based on the following treatments: lidocaine alone (L group), lidocaine + butorphanol (LB group), or lidocaine + tramadol (LT group). After mandibular nerve block with opioids as an adjunct to local anesthetics, the onset time, duration of action, and depth of anesthesia were evaluated using a quantitative method through neuromuscular blockades (NMBs) monitoring. The onset time of nerve block was 4.60 ± 2.06 min, 2.00 ± 0.00 min, and 2.60 ± 1.62 min in the L, LB, and LT groups, respectively; however, there was no statistically significant difference. The duration of nerve block was 111.88 ± 34.78 min, 302.00 ± 76.72 min, and 260.40 ± 49.88 min in the L, LB, and LT groups, respectively, with a significant difference between L and LB groups. The LB group demonstrated a more profound depth of anesthesia compared to the L and LT groups. In this study, using a quantitative method through NMBs monitoring, it was demonstrated that lidocaine and butorphanol in combination can increase the duration of nerve block and more profound the depth of anesthesia rather than lidocaine alone. Additionally, the combined use of lidocaine and opioids presented an objective indicator that could provide a more clinically stable nerve block.

A 10-year-old spayed female beagle dog presented with a 2-month history of third-eyelid elevation in the left eye (OS). Ophthalmic examination revealed slightly diminished corneal and palpebral reflexes along with exophthalmos in the OS. Schirmer's tear test and intraocular pressure values were within the normal range for the OS. Slit-lamp biomicroscopy revealed protrusion of the third eyelid and corneal opacity in the OS. Fundoscopy revealed a prominent black mass in the OS covering the optic nerve. Tapetal hyper-reflectivity was also observed around the mass. Ocular ultrasonography showed a 0.74 × 0.67 cm echogenic posterior segment mass around the optic nerve protruding into the retrobulbar space. Computed tomography revealed a contrast-enhanced soft tissue lesion in the posteromedial aspect of the left eyeball protruding into the retrobulbar region, and the optic nerve was suspected to be involved. No evidence of osteolytic changes in the adjacent bone or distant metastasis was observed. Enucleation was performed to prevent potential metastasis or local invasion of the mass and to relieve discomfort due to exposure to keratopathy resulting from lagophthalmos. Histopathological examination revealed a central choroidal melanocytoma extending into the optic nerve. No local recurrence was detected until 16 months postoperatively.
Background: Mandibular third molar removal is the most common surgical procedure encountered in oral and maxillofacial clinics. It also presents the greatest challenges and controversies for surgeons when surgical removal is considered. Furthermore, diverse anesthesia results and success rates are achieved after using the same concentrations of different solutions or the same amounts of local anesthetics. The purpose of this study was to examine the efficiency of using double-cartridge (3.4 ml) 4% lidocaine (high concentration) and 4% articaine with a 1:100000 epinephrine infiltration in the retromolar region for impacted lower third molar surgery. Methods: This double-blind study included 30 patients with symmetrically impacted lower third molars. The patients were randomly selected to receive 4% articaine on one side and 4% lidocaine on the other, as a local anesthetic for third molar surgery. The onset, duration of soft-tissue numbness, pulpal sensitivity, amount of additional local anesthetic needed, pain score during the surgical procedure, and duration of the operation were recorded. Results: The results of this research indicate that 86.7% of the operations in the 4% articaine group and 83.3% of those in the 4% lidocaine group were successful. Furthermore, the outcomes in both groups were not statistically significant (P > 0.05). Numbness onset occurred faster in the articaine group than it did in the lidocaine group. However, the duration of soft-tissue anesthesia and pain scores recorded immediately postoperatively were similar. Conclusion: It is concluded that 4% lidocaine and 4% articaine had a similar infiltration efficacy in the retromolar region and both local anesthetics are adequate for impacted lower third molar surgery. There were no statistically significant differences between the two local anesthetics regarding pain control and the duration of soft-tissue numbness during the procedure.
The objective of this study was to compare the biocompatibility for local irritation and bioavailability of $Gentacol^{TM}$ and $Collatamp^{TM}$, after single intramuscular loading in rats. Sixty-six male Sprague-Dawley rats were divided into 4 groups; (1) any test materials were not applied into the quadriceps muscles (control group, N = 6), (2) Gentamicin was injected into the quadriceps muscles (Gentamicin group, N = 6), (3) Collatamp was applied into the quadriceps muscles (Collatamp group, N = 27), and (4) Gentacol was applied into the quadriceps muscles (Gentacol group, N = 27). The concentration of gentamicin in muscles was gradually decreased with time after loaded in the both $Gentacol^{TM}$ and $Collatamp^{TM}$ loaded regions. No detectable gentamicin was observed in the plasma of $Gentacol^{TM}$ and $Collatamp^{TM}$ loaded rats. Histologically, moderate to severe inflammatory cell infiltrations including PMN, lymphoid cells and macrophages were observed with slight to moderate edematous changes of muscle fibers after intramuscular injection of gentamicin. However, these histopathological changes of gentamicin injection induced local irritations were dramatically decreases after intramuscular loading of $Collatamp^{TM}$ and $Gentacol^{TM}$. These results suggest $Gentacol^{TM}$ may show favorable local bioavailability and induce only slight local irritations as comparable as $Collatamp^{TM}$ without systemic exposures in the condition of this experiment.
In South Korea, six large outbreaks of highly pathogenic avian influenza (HPAI) have occurred since the first confirmation in 2003 from chickens. For the past 15 years, HPAI outbreaks have become an annual phenomenon throughout the country and has extended to wider regions, across rural and urban environments. An understanding of the spatial epidemiology of HPAI occurrence is essential in assessing and managing the risk of the infection; however, local spatial variations of relationship between HPAI incidences in Korea and related risk factors have rarely been derived. This study examined whether spatial heterogeneity exists in this relationship, using a geographically weighted Poisson regression (GWPR) model. The outcome variable was the number of HPAI-positive farms at 252 Si-Gun-Gu (administrative boundaries in Korea) level notified to government authority during the period from January 2014 to April 2016. This response variable was regressed to a set of sociodemographic and topographic predictors, including the number of wild birds infected with HPAI virus, the number of wintering birds and their species migrated into Korea, the movement frequency of vehicles carrying animals, the volume of manure treated per day, the number of livestock farms, and mean elevation. Both global and local modeling techniques were employed to fit the model. From 2014 to 2016, a total of 403 HPAI-positive farms were reported with high incidence especially in western coastal regions, ranging from 0 to 74. The results of this study show that local model (adjusted R-square = 0.801, AIC = 954.5) has great advantages over corresponding global model (adjusted R-square = 0.408, AIC = 2323.1) in terms of model fitting and performance. The relationship between HPAI incidence in Korea and seven predictors under consideration were significantly spatially non-stationary, contrary to assumptions in the global model. The comparison between global Poisson and GWPR results indicated that a place-specific spatial analysis not only fit the data better, but also provided insights into understanding the non-stationarity of the associations between the HPAI and associated determinants. We demonstrated that an empirically derived GWPR model has the potential to serve as a useful tool for assessing spatially varying characteristics of HPAI incidences for a given local area and predicting the risk area of HPAI occurrence. Considering the prominent burden of HPAI this study provides more insights into spatial targeting of enhanced surveillance and control strategies in high-risk regions against HPAI outbreaks.
This study was designed to examine therapeutic effect of bee(Apis mellifera L.) venom in calves with bacterial diarrhea. Calves with bacterial diarrhea were administered with bee venom and therapeutic drug, respectively. In the bee venom-treated group, 69 calves were acupunctured once a day for 3 conseutive days. Two local acupoints of Jiao-chao(GV-1, at the indentation between the base of tail and the anus) and Bai-hui(GV -20, in the dorsal midline of the lumbo-sacral space) were stung by the bee. In the therapeutic drug-treated group, 55 claves were intramuscularly injected with a standard dosage of antibiotic (ciprofloxacin, 2.5 mg/kg of body weight) and antidiarrheal drug (berberine cholride, 10mg/head) once a day for 3 consecutive days. At post-treatment, 81.2% of the bee venom-treated calves and 76.4% of the therapeutic drugtreated calves were recovered from bacterial diarrhea. Bee acupuncture therapy showed in calves without side effects such as allergy hemorrhage, or infection. It might be concluded that apitherapy was affective in controlling of calves with bacterial diarrhea.
An 8 month-old male Maltese (weighing 2.0 kg) was referred with loud heart murmur at routine physical exam in local animal clinic. Electrocardiogram found left ventricular hypertrophy pattern (4.5 mV R-wave). Diagnostic imaging studies revealed the elongation of left ventricle (LV) with classic triple bumps on the main pulmonary artery, aorta and left atrium on the ventrodorsal view of radiograph. Echocardiography revealed patent ductus arteriosus (PDA) duct and continuous turbulent shunt flow (maximal velocity 4.83 m/s) between the aorta and pulmonary artery with left to right direction. The PDA in this dog was successfully closed through femoral vein (transvenous approach) using a 5 mm Amplatz$^{(R)}$ Canine Duct Occluder. To the best of author's knowledge, this is the first case of PDA occlusion treated with Amplatz Canine Duct Occluder through femoral vein.
