    A 5-day-old Japanese Black female calf showing abdominal distension was presented to the Veterinary Medical Teaching Hospital of the Iwate University for diagnosis and treatment. The calf also exhibited astasia, dehydration, and a breath smelling of urine. Abdominal radiography and ultrasonography revealed a large volume of effusion in the abdominal cavity, and abdominal paracentesis showed uroabdomen. The calf was suspected of having a rupture of the urinary bladder and was subjected to laparotomy in a supine position after intravenous administration of xylazine hydrochloride 0.1 mg/kg. An abnormal electrocardiogram was observed immediately after beginning the surgery, and cardiac arrest occurred during the process of removing the fluid. Normal sinus rhythm returned after a rapid intravenous infusion of acetated-ringer solution with an injection of vasopressors. A laceration that existed at the dorsal part of the bladder was sutured, and the abdominal wall was closed after intraperitoneal irrigation. The calf was systemically administered with an antibiotic for four days after surgery. One year later, the calf was reportedly in good condition and growing well.

    The presence of the articularis genus muscle between the femur and patellae of a cat was confirmed. The main development of this muscle occurred during the first year after birth, and it showed a tendency to be displaced by adipose tissue with aging. These results may account for difficulties in locating or identifying the muscle. The distribution density of the muscle spindles was higher than that seen in the quadriceps femoris muscle and they remained among the adipose tissue that filled the muscle tissue. It was suggested that the articularis genus muscle has a function as a kinesiological monitor rather than as that related to the tension of the knee joint capsule.

    A 20-year-old female macaroni penguin (Eudyptes chrysolophus) with a large black mass of the beak was examined pathologically. At necropsy, the mass was solid, irregular and black color, and had invaded the upper jaw and the oral cavity. Metastasis of the tumor to the thoracic subcutaneous tissue was also observed. Histopathologically, epithelioid or spindle tumor cells with many intracytoplasmic black pigments and eosinophilic abundant cytoplasm showed a solid, invasive proliferation pattern. Tumor cells were positive for S-100 and PCNA and negative for Desmin and Pan-cytokeratin by an immunohistochemical analysis. Electron microscopically, intracytoplasmic melanin granules and melanosomes were observed. Based on these findings, the lesion is diagnosed as a malignant melanoma of the beak in a macaroni penguin.
