Seung-gon Lee,Dong-gun Kim,Joon-seok Lee,Ho-hyun Kwak,Hyun-sook Nam,Heung-myong Woo*, In-Chul Park**, Changbaig Hyun1,In-chul Park,Chang-baig Hyun 한국임상수의학회 2006 한국임상수의학회지 Vol.23 No.3
A 10-year-old intact female Miniature Schnauzer dog was referred with the primary complaint of persistentanorexia, remittent fever, vomiting and abdominal pain. Hemogram suggested a chronic inflammatory disease. Serumbiochemistry showed moderate hepatobiliary cellular damage with severe cholestasis. Abdominal radiography andultrasonography revealed hepatomegaly, choleliths and sludges in gall bladder and small stones in urinary bladder. Basedcholecystectomy and cystectomy, choleliths and uroliths were removed from gall bladder and urinary bladder,respectively. The clinical condition was dramatically improved after surgery.
Mitral valve prolapse in Cavalier King Charles Spaniel: A review and case study
Changbaig Hyun 대한수의학회 2005 Journal of Veterinary Science Vol.6 No.1
A 5 year-old spayed female Cavalier King Charles Spaniel was presented after a 3- to 5-day onset of severe respiratory distress. The dog also had a history of several episodes of syncope prior to presentation. A comprehensive diagnostic investigation revealed a midsystolic click sound on cardiac auscultation, signs of left sided cardiac enlargement in ECG and thoracic radiography, mitral valvular leaflet protrusion into left the atrium, decreased E-point-to septal separation (EPSS) and mitral regurgitated flow in echocardiography, all of which are characteristic signs of mitral valvular prolapse. After intensive care with antidiuretics and a vasodilator with oxygen supplement, the condition of the dog was stabilized. The dog was then released and is being medicated with angiotensin converting enzyme (ACE) inhibitor with regular followup

This study evaluated the efficacy and safety of medical shampoo containing terbinafine hydrochloride and chlorhexidine gluconate in dogs with dermatophytos is complicated with bacterial infection. Although several studies in dogs and cats with fungal dermatitis have found that oral administration of terbinafine is effective for controlling clinical signs, the topical form of terbinafine has rarely been studied in dogs and cats. Therefore, this study evaluated the efficacy of medical shampoo containing terbinafine hydrochloride and chlorhexidine gluconate in dogs with dermatophytos is complicated with bacterial infection. Eight dogs infected with Microsporum spp. complicated with bacterial infection were enrolled in this study. These dogs were further blindly divided into Group 1 (no treatment, fourdogs) and group 2 (treated with medical shampoo with terbinafine/chlorhexidine, four dogs). Clinical improvement was evaluated using bacterial and fungal cultural evaluation combined with clinical evaluation. This study found that the medical shampoo has sufficient efficacy to treat varying degrees of dermatophytosis complicated with bacterial infection in dogs, although the speed of improvement differed according to the degree and type of infection. Our study also found that combined therapy using antifungal and antibacterial agents can improve clinical signs more effectively and rapidly, suggesting that concurrent bacterial infection plays a significant role in the development of dermatitis

This study was conducted in order to evaluate three different non- invasive blood pressure measurement methods (NIBP) in comparison with direct blood pressure measurements in anesthetized dogs. Ten normal healthy Beagle dogs (mean age; 3.7 ± 1.01 yrs, mean body weight 10.2 ± 1.15 kg) were enrolled in this study. BP was measured using three different methods, i.e., Doppler (DOP), oscillometric, and high density oscillometric (HDO) methods, simultaneously, five times in each subject under anesthesia at three different locations (right, left front legs, and tail). The blood pressure value measured by the Doppler method was the closest to the value measured by the direct method. Although the accuracy and consistency of BP measured by three different non-invasive methods differed according to the method, all methods, except the conventional oscillometric method, were acceptable for monitoring systolic blood pressure in anesthetic dogs. The inter-measurement variations in DOP and HDO were minimal without affecting the consistency of the test results

A 3.5-year-old intact female miniature poodle (weighing 2.7 kg) was referred to the Veterinary Teaching Hospital at Kangwon National University, because of inadvertent aortic embolization, by an occlusion coil used for the closure of patent ductus arteriosus (PDA). The coil was found at the site of the branching renal arteries in the abdominal aorta. A foreign body forceps with a three-wire nail tip was used, with fluoroscopic guidance, to retrieve the coil. After the removal, the dog was treated with heparin to prevent thromboembolization.
Atropine Induced Paradoxical Atrioventricular Conduction Block in a Jindo Dog

laboratory tests performed prior to surgery found no significant abnormalities, which might increase risks associatedwith general anesthesia. The dog was premedicated with atropine, induced general anesthesia with thiopental sodiumand maintained with isoflurane. Forty minutes after surgery, the dog was suddenly bradycardic. Atropine (18 ug/kg)was slowly infused intravenously to normalize heart rate. However, paradoxically the dog showed slower heart ratewith intermittent atrioventricular block (2nd degree type I) after atropine infusion. The dogs rhythm was returned toa rare case of paradoxical atrioventricular block inducedby high dose of atropine in a dog.
Familial mitral valve prolapse in a Maltese dog family
Sang-Il Suh,Ran Choi,Changbaig Hyun 충북대학교 동물의학연구소 2015 Journal of Biomedical and Translational Research Vol.16 No.2
Mitral valvular prolapse (MVP) in dogs is characterized by myxomatous valvular degeneration, which is caused by abnormal valvular thickening and incomplete coaptation of the mitral valve leading to mitral regurgitation. Mitral regurgitation causes left atrial and left ventricular enlargement. Pathogenesis of the disease is unknown, although some studies have suggested the involvement of endothelin and systemic connective tissue diseases. Mitral valvular prolapse in dogs commonly occurs in aged small dog breeds, including Malteses and Shih Zhus. This case study investigated the clinical features of an affected Maltese family and performed pedigree analysis. To the best of the authors’ knowledge, this is the first report of putative familial mitral valve prolapse and regurgitation in Maltese dogs. All family members in this study showed degenerative valvular changes and echocardiographic features of mitral valvular prolapse. Although disease progression differed, all dogs progressed to advanced heart failure stage within 2-3 years after diagnosis. Therefore, this is the first study to identify putative familial mitral valve prolapse in Maltese dogs. This finding suggests strong genetic etiology involved in the development of degenerative mitral valve disease in Maltese dogs. Furthermore, this finding could be a valuable resource for the identification of gene mutations in dogs with familial mitral valvular prolapse.
