One-lung ventilation (OLV) is the isolation and selective ventilation of one lung field. OLV allows the collapse of lung lobes on the side of the thoracic surgical approach to facilitate observation of intrathoracic structures and to achieve lung immobility. OLV be achieved by endotracheal intubation with double lumen tubes or bronchial blockers. In this study, cardiopulmonary consequences of two-lung ventilation (TLV), OLV and Re-TLV (TLV after OLV) were evaluated in 5 dogs. The dogs were anesthetized with mask induction and maintained with isoflurane in oxygen. Tidal volume and respiratory rates were set to maintain end-tidal CO₂ at 40±2 mmHg during instrumentation.

This study tested the effect of a trivalent (feline panleukopenia; FPV, feline viral rhinotracheitis; FHV, feline calicivirus infection; FCV) inactivated vaccine in cats. The vaccine was tested for the safety in guinea pigs, mice and cats. Also, it was tested for the efficacy in cats. The vaccine was inoculated to cats at 7~9 and 10~12 weeks of age (conventional schedule) and the serological response to vaccination was assessed and was compared to the unvaccinated group. All cats were bled by jugular venipuncture for FPV, FHV and FCV specific serological test (virus neutralizing antibody, VN) at 7~9, 10~12 and 13~15 weeks.

Porcine juvenile pustular psoriasiform dermatitis (PJPPD) is a disease of young pigs and characterized by nonpruritic round eruption of skin. The cause of this disease is yet undetermined but is presumed to be genetic predisposition. There may be few opportunities for veterinarian to detect this disease compared with actual situation in field because these lesions resolve spontaneously in two months. The authors detected spontaneous PJPPD case and performed clinical and pathological studies on three pigs from one farm. The specific skin lesions were observed in the forty-day old pigs of mixed breed, which were produced by the sows received semen from the same boar, restrictively.

Aeromonas hydrophilia infection was diagnosed in captive Jackass penguins (Spheniscus demersus). Seven Jackass penguins showed clinical signs including depression and anorexia with greenish vomiting, but four penguins were died although extensive treatment was carried out. At necropsy, the penguins appeared to have hemorrhage and catarrhal inflammation of the small and large intestines and severe enlargement of the right hepatic lobe, elongation of the gall bladder and pyloric ulceration of the stomach. The ovaries observed atrophy and congestion. Microscopically, there were congestion, fat droplet within the cytoplasm of the hepatic cell, infiltration of lymphocytes in the stomach, vilous detachment and destroyed glandular epithelium in the small and large intestines.

This study was performed to elucidate the effect of acupuncture and aqua-acupuncture in dogs. Each group was divided into control (18 dogs), PC-6 (6 dogs) and BL-21 (6 dogs) group for the antiemetic effect of acupuncture, respectively. And, the animals were divided into control (18 dogs), PC-6 (18 dogs) and BL-21 (18 dogs) group for the antiemetic effect of aqua-acupuncture with metoclopramide, respectively. 2% xylazine was injected to the all dogs to induce the emesis, and acupuncture and aqua-acupuncture treatment (0.5% metoclopramide) were applied to animals for 20 min. before xylazine injection, respectively.

Adhesions are the most common postoperative complication in intestinal surgery in dogs. This study was aimed at verify to the efficacy of sodium carboxymethylcellulose (SCMC) in the adhesion prevention during healing of intestinal anastomosis. Twenty three healthy dogs were taken with average 4.17 years and weight was 5.68 kg and divided into 4 groups. The dogs of group Ⅲ and Ⅳ, a pedicle of greater omentum was wrapped around the suture line. In the animals of group Ⅱ and Ⅳ, 1% SCMC was infused (5 ml/kg, IP) at just before closure of the abdominal cavity. Two weeks after surgery, animals were reoperated and the adhesions were evaluated and graded.

Color Doppler imaging (CDI) was carried out to evaluate the anesthetics effect on ophthalmic circulation using CDI-derived resistive index (RI) values. CDI was preformed on 24 dogs, and RI values were calculated for the medial long posterior ciliary artery (mLPCA) and ophthalmic artery (OA) before and after administration of anesthetics. After administration of benoxinate or acepromazine, a significant change of the mLPCA RI was not found. But, a significant decrease of the RI following ketamine (p less than 0.001) or xylazine (p less than 0.01) administration could be observed as compared with the self-control. Mean RI value of OA also showed this same trend.

A 1.35 kg, three-year-old, female, Yorkshire terrier was referred to the veterinary medical teaching hospital of Chungnam National University with an alopecia, scale, polydipsia and polyuria. During hospitalization, the patient revealed swelling and pain of all four foot pads. The hematology indicated nonregenerative anemia. Blood serum chemistry revealed elevation of BUN, serum creatinine and phosphorus contents. Radiographs of feet revealed increased radiodensity in the soft tissue of the foot pad. In ultrasonographs of abdomen, kidneys showed diffusely echodense renal cortex with loss of the normal corticomedullary boundary.

This study was carried out to investigate the skeletal measurement of the sternum and ribs at 60-, 90-, 120-day-old fetuses and neonates of Korean native goats. The total length and width of the ossified part of the sternebrae and ribs were observed at 60-, 90-, 120-day-old fetuses and neonates. The ossification of the ribs from the 1st to the 8th rib was observed in 60-day-old fetuses, but not observed from the 9th to the last rib. In the 90-day-old fetuses, all ribs were observed having ossified parts. In the 60-day-old fetuses, all sternebrae were not observed having ossified parts.

Immu-Forte composed of chitosan, β-glucan, manno-oligosaccharide and pangamic acid was evaluated for its effectiveness as a nonspedific immunostimulator in mice. The effects of Immu-Forte were determined by analysis of cytokines using ELISA and phenotype of leukocyte subpopulations using monoclonal antibodies specific to mouse leukocyte differentiation antigens and flow cytometry. All T cells, all B cells, CD4 T cells, CD8 T cells, macrophages, IL-2, IL-4, IL-12 and IFN-r in Immu-Forte A-treated group increased in 1 months posttreatment and were significantly higher (p less than 0.05) than that of control at 1 months posttreatment.
