A 1.6-year-old, intact male beagle dog was presented with three day history of odynophagia and anorexia. According to the history and radiographic findings, the patient was diagnosed with esophageal and gastric foreign body due to ingesting fishhooks. Gastroesophagoscopy revealed that one fishhook located in the thoracic esophagus cranial to the heart base and the other located in the cardia region were connected with a single fishing line. Gastrotomy was performed to remove the fishhook in the cardia region and to sever the connecting fishing line. After gastrotomy, endoscopic attempts to remove the esophageal fishhook with a three, five pronged endoscopic grasping forceps, and a biopsy were unsuccessful because the fishhook was embedded deeply in the mucosa membrane. A handmade cerclage wire(16G) shaped like a snare forceps was advanced into the esophagus while visualizing the fishhook endoscopically. The cerclage wire was used to hang and retract the foreign body. The fishhook was retracted orally, resulting in successful removal. Ten days after the operation, the patient fully recovered and was discharged.

The esophageal perforation with foreign body is very rare. It is usually caused by sharp metallic foreign body or bone piece and rarely caused by long standing of foreign body. The authors observed 5 cases of esophageal perforation with foreign body among 48 cases of esophageal foreign body during the period from Jan. 1976 to Dec. 1977. There were two cases of esophageal foreign body with curved wire. a case with bone piece. a case with safty pin and a case with fish hook.

Compared with type specimen Acanthobelba tortuosa Enami and Aoki, 1993, a new species, A. heterosetosa sp. nov., of oribatid mites collected from Mt. Jiri has the following characteristic figures. Sensillus is long, slightly thickened at distal part, and covered with barbs sparsely. A pair of prodorsal tubercles Da are present. Natogastral frontal tubercles sa is elongated rather than hooked. Dorsal setae are not the same in shape and length: setae c1 and c2 are thick, blunt at tip, covered with small barbs and curved several times, but others are smooth.

We have recently removed five interesting foreign bodies successfully. Case 1. A broken tracheostomy outer cannular tube in the right main bronchus of a 7 year old boy. Case 2. An acupuncture needle in the trachea of a fifty-one year old man. Case 3. A fish hook with thread in the second isthmus of esophagus of a 10 month old girl. Case 4. An opened safety pin (sharp point toward cephalad) in the third isthmus of esophagus of a sixteen year old boy. Case 5. A big lead bullet which went through soft tissue below right mastoid tip and lodged at the mid-point between right mastoid process and foramen magnum(skull base) of a twenty year old boy, was removed surgically uneventfully.

Two specimens of the Cenozoic fish fossils were discovered from the Miocene Duho Formation of Uhyeon-dong, Pohang, Korea. These fossils are identified as Pleuronichthys sp. based on the following- firstly, front dorsal fin rays elongated to the upper part of neurocranium, Secondly, right sided orbit of neurocranium, Thirdly, presence of urohyal like fish-hook, Fourthly, curved sciatic part of the urohyal, Fifthly, presence of postcleithrum, Sixthly, over 27 centrum, Seventhly, elongated first pterygiophore of the anal fin rays, Eightly, c-shaped inner side of urohyal, Ninthly, small or few cardiac apophysis, and Tenthly, presence of many spots on body. These fossils of Pleuronichthys represent the first record in East-Asia. Two specimens are anatomically different in the extent of the asymmetry and the flatness of skull. This represents the unique ontogeny stage of the Pleuronectidae, because they accompany the above anatomical difference when they transform from pelagic lifestyle to benthic lifestyle.

Four entities of the Cenozoic fish fossils were discovered in the Miocene Duho Formation, Pohang, Korea. these fossils were identified as the first Pleuronectiformes in Korea based on the following-the presence of postcleithrum, the elongation of the first proximal pterygiophore of the anal fin ray, almost consistent presence of two proximal pterygiophore of the anal fin rays between the two adjacent hemal spines, the fusion of the first and second hypurals, the fusion of the third and fourth hypurals and the first preural centrum, the presence of well-developed anteriormost plate-like neural spine, the presence of the urohyal like fish-hook and its elongated sciatic part, and the division of the parahypural from the first preural centrum. On the other hand, geological studies about the Duho Formation consistently claimed that shallow-sea creatures were washed away by meteorological events such as a great flood and deposited at the bottom of deep-sea by the turbidity current. However, in Duho Formation, only shallow-sea ones have been discovered thus far. This study reported that Flat fish, deep-sea creature, was discovered in Duho Formation for the first time in Korea.
