  • We followed the development of Pacific herring Clupea pallasii larvae after natural hatching in Korean coastal waters off Dadaepo, where the water temperature was $9^{\circ}C$. Twenty days after hatching, the larvae had (i) reached a total length (TL) of 10.8-12.2 mm, (ii) developed 9-11 dorsal fin rays, and (iii) branched melanophores along the dorsal line of the gut in the anterior half of the body and along the posterior half of the dorsal and ventral line. Thirty days after hatching, the larvae had reached 12.2-13.5 mm TL, and the number of dorsal fin rays had increased to 13-14. Thirty-five days days after hatching, the larvae had reached 14.0-14.7 mm TL, and the posterior ends of their notochords had begun to flex upward. Forty-five days days after hatching, the larvae had (i) reached 15.6-15.9 mm TL, (ii) a complete set of dorsal fin rays (15-16), (iii) 12-13 anal fin rays, and (iv) branched melanophores along the dorsal part of the lateral surfaces of the head behind the caudal terminus. Preflexion, flexion and postflexion stage larvae had TL values of 13.5 mm, 14.0-15.3 mm, and 15.6-15.9 mm, respectively.

  • Seventeen specimens of leptocephali [9.8-44.5 mm total length (TL)], of the family Ophichthidae, were collected from southeastern waters off Jeju Island and the Korea-Japan intermediate zone, and identified by means of morphology and genetics. These specimens were identified as belonging to the subfamily Ophichthinae based on various combinations of morphological characters: 211-215 total myomeres; 7 gut swellings; 2 liver lobes connected with the gall bladder on the second lobe; 6-7 postanal pigments present from anus to caudal margin. An analysis of the partial 12S rRNA sequences (849 base pairs) of mitochondrial DNA showed that our specimens must be Ophisurus macrorhynchos because their sequences were concordant with those of the adult O. macrorhynchos (genetic distance = 0.000). Furthermore, their total myomeres were consistent with those of the O. macrorhynchos adult. This is the first time that the morphological characteristics of O. macrorhynchos leptocephali have been described for Korean waters, and we suggest diagnostic characteristics for the genus Ophisurus leptocephali. We hypothesize that one of the spawning grounds of O. macrorhynchos is located in the southeastern part of Jeju Island.

  • A study was performed to analyze the biochemical composition (moisture, protein, fat, ash, salt value, iron, calcium and phosphorus) of raw and salted hilsa. Pure (with less than 1% impurities) and clean dry salt was used (fish weight : salt weight = 3 : 1) for salting the hilsa. The nutrients values of the hilsa from two different regions were significantly (p < 0.05) varied. The biochemical compositions were also different before and after the processing of the hilsa. Riverine hilsa contains relatively more moisture ($57.79{\pm}0.51%$) and protein ($15.65{\pm}0.50%$) than marine hilsa. Fat ($16.39{\pm}0.51%$) and salt ($1.80{\pm}0.14%$) contents are higher in marine hilsa; whereas the ash ($7.88{\pm}0.35%$) content was higher in the riverine hilsa. Minerals like iron ($4.92{\pm}0.32mg/100g$) and calcium ($480.02{\pm}6.73mg/100g$) remain in large amounts in the marine hilsa, but the phosphorus ($112.36{\pm}4.40mg/100g$) content remains at a high level in the riverine hilsa. In addition, the protein (raw condition, $18.54{\pm}0.46%$, riverine; $17.12{\pm}0.42%$, marine and salted condition, $32.54{\pm}0.5%$, riverine; $27.31{\pm}0.48%$, marine) and fat (raw condition, $15.41{\pm}0.46%$, riverine; $19.07{\pm}0.51%$, marine and salted condition, $11.58{\pm}0.39%$, riverine; $13.6{\pm}0.55%$, marine) contents were higher in the abdominal region of the riverine and marine hilsa both in the raw and salted conditions than in the head and caudal region.

  • Five dogs presented to the Veterinary Medical Teaching Hospital of the Konkuk University and Hangang Animal Hospital with a history of foreign body ingestion. On physical examination, five dogs showed lethargy, anorexia, or vomiting. Plain radiographs revealed that radiopaque foreign bodies lodged in the heart base or caudal thoracic esophagus. Positive contrast esophagogram revealed that large foreign bodies severely expanded the esophagus and there was no evidence of leakage of the contrast agent from the esophagus into the thoracic cavity. Gastrotomy for retrieval of esophageal foreign bodies using long forceps technique was performed. Esophageal foreign bodies were successfully retrieved in all dogs. The follow-ups were completed 10 days to 2 years after surgery. The follow-up information was based on physical examination by veterinarians and telephone interview with owners. The owners reported that there was no evidence of complications related to surgery such as vomiting, regurgitation, dysphagia, gagging, hyper-salivation, or anorexia in all dogs.

  • During the course of taxonomic study on the genus Chromis from the southern coastal waters off Cheju Island during April-August 1993, eight specimens have been classified as Chromis analis(Cuvier) for the first time in Korea, and thus described here as new to the Korean fish fauna. Damselfish, Chromis analis was originally described by Cuvier and Valenciennes(1830) from Ambonia, Indonesia. Chromis notatus is the only species to date in the genus Chromis distributed around Korean waters, according to Chyung(1977). Chromis analis is distinguished from Chromis notatus by three spiniform procurrent caudal rays, a deeper body and a golden or brown yellowish body and fin color. Norang-ja-ri-dom is proposed as the Korean name for Chromis analis.

  • This study was performed to investigate the effects of Kamigyemyoungsan and each compositive herbs on the intravascular coagulation and subcutaneous hematoma. The intravascular coagulation was induced by the injection of endotoxin into the caudal vein of the rats. These rats were treated with endotoxin after administering orally extracts of Kamigyemyoungsan and each compositive herbs. Then the number of platelet, prothrombin time, the concentration of fibrinogen and FDP(fibrinogen degration product), hematocrit and RBC and WBC were measured. The subcutaneous hematoma was induced by the subcutaneous injection of the autologous whole blood to produce clotting in situ in rats. Then the extracts of Kamigyemyoungsan and each compositive herbs were administered orally. The lesions were then dissected and observed. The results were obtained as follows ; 1. The number of platelets of the trial groups was increased as compared with the control group, and revealed significance in sample Ⅰ. 2. The concentration of fibrinogen of the trial groups was increased as compared with the control group, and revealed significance in sample Ⅰ, sampleⅡ and sample Ⅴ. 3. The prothrombin time was shortened significantly in the trial groups, except sampleⅡ and sampleⅣ as compared with the control group. 4. The concentration of FDP decreased in the trial groups, and revealed significance in sample Ⅰ and sample Ⅵ as compared with the control group. 5. The hematocrit significantly increased in sample Ⅰ, sampleⅢ and sample Ⅵ as compared with the control group. 6. The number of RBC significantly increased in sample Ⅵ only as compared with the control group. 7. The number of WBC significantly increased in the trial groups, except sampleⅣ and sample Ⅵ as compared with the control group. 8. Histologically, the lesions in the trial groups showed significantly thinner fibroblastic neomembrane than the control group, except sampleⅢ. According to the above results, it is considered that Kamigyemyoungsan and each compositive herbs have inhibitive effects on the thrombosis and the fibroblastic neomembrane development. Therefore, it seems to be applicable to the diseases related to thrombosis and hematoma.

  • Three dogs that had a history of abdominal distension were referred to the hospital. All were female with unilateral involvement. History and clinical signs were nonspecific. Abdominal radiographs demonstrated that the abdomen of all cases was filled with large masses. At laparotomy, all masses were kidney tumors with invasion around tissue. The tumors were soft, irregular, creamish and confined within the capsule. One case had liver metastasis. Another case was found to have adrenal gland metastasis. One case had caudal vena cava invasion. A ureteronephrectomy was performed unilaterally in all cases. In the microscopic appearances, all the tumors had malignant features with nuclear pleomorphism and amount of necrosis. Three cases were diagnosed as renal carcinomas.

  • Complete ruptures of the Achilles tendon were repaired in two hunting dogs of a 3-year-old, 20 kg and a 4-year-old, 14 kg with non weight bearing lameness. Both dogs were injured by wild animals and the skin defect was showed on the caudal surface of the right limb. Surgical repair involved the attachment of the ruptured tendon with a three-loop pulley method, using nonabsorbable suture materials. After surgical procedure, a bivalved cast was applied and maintained for 6 weeks. Exercise was restricted for 2 weeks more before gradually returned to normal. Gait and standing posture of dogs were returned to normal during the follow-up of 10 weeks.

  • A 7-year-old female, Jindo dog was referred to the Veterinary Teaching Hospital with mild dyspnea and anorexia due to a gunshot trauma. The dog was wounded in the thoracic region 3 days ago. Plain radiographs showed the left 8th rib fracture, interstitial pattern in the left caudal lung field and pleural effusion. Abdominal radiographs showed the lead bullet. Computed tomographs(CT) showed the size of pulmonary contusion, laceration, lung parenchymal injuries, hemothorax and perforation of abdominal wall. The therapeutic plan was based on abnormalities seen on CT scans but not clearly seen in survey radiographs. Thoracic CT significantly provides even more informations compared with the corresponding radiographs in thoracic gunshot trauma. Although thoracic survey radiographs are useful as a screening tool, CT is highly sensitive in detecting thoracic injuries after thoracic trauma and is superior to routine thoracic survey radiographs in visualizing lung contusion, pneumothorax and hemothorax. Therefore, we recommend CT in the initial diagnostic work-up of patients with thoracic injuries and with suspected chest trauma because early and exact diagnosis of all thoracic injuries along with sufficient therapeutic consequences may reduce complications.

  • An-11-year-old male Shih-tzu was admitted to emergency care unit of Haemaru Referral Animal Hospital with signs of dyspnea, anuria and depression. There were abnormalities on complete blood count and serum chemistry included leukocytosis with mild left shift, mild azotemia, and increased ALT activity. Fluid therapy(0.9% saline, 40 ml/hr) and antibiotics were immediately initiated. The patient began to vomit after 5 hours' rest and pale mucous membrane, bradycardia, and hypertension were noted. Abdominal ultrasonography revealed enlarged left adrenal gland and thrombus in caudal vena cava(CVC). Result of ACTH stimulation test was normal. Cytology of ultrasound-guided FNA smears showed numerous naked nuclei, which was suggestive of adrenal medullar tumor. Concentrations of 24 hour urine metanephrine and normetanephrine was moderately increased compared to those of a control dog. Adrenal mass was surgically removed, and biopsy of the CVC mass was obtained. After surgery the patient began to recover but the dog acutely developed cardiopulmonary arrest and died. On histopathology the adrenal mass and biopsy of the CVC mass were consistent with pheochromocytoma. On electron microscopic view norepinephrine specific granules were found in the cytoplasm of tumor cells.
