  • Pathological findings of natural cases of rabbit hemorrhagic disease was investigated. Clinically inappentence, increase in body temperature, depression, bloody foam from nostrils, and sudden death were recognized. Characteristic anatomical findings were hemorrhages in the lungs, liver, kidneys, and heart. Intestinal catarrh and retention of turbid urine in urinary bladder were also often observed. Severe .necrosis of hepatic cells, massive hemorrhages in many organs and membranous glomerulonephritis with hyaline droplet formation were characteristic changes under the microscopy. Perivascular cuffing of brain and catarrhal enteritis were also seen in many cases.

  • Angiofollicular lymph node hyperplasia is a relatively rare benign lesion. It develops most often in the mediastinum, but also it found in other area of the body, usually where lymph nodes are normally found. There are histologically divided hyaline vascular type, plasma cell type and transitional type. The lesions were discovered most often on routine roentgenograms, and complete surgical excision is the treatment of choice. Recently, the authors experienced a case of angiofollicular lymph node hyperplasia, transitional type, located in the right hilar area. The lesion was removed and the patient is in good condition postoperatively. Now we report this case with review of previously reported literatures.

  • Catsleman's disease is a type of angiofolliculr lymph node hyperplasia and its etiology is not known yet. It usually presents with the mediastinal mass but rarely with the parotid mass. There are only five cases previously reported in the literatures. It has two pathologic types, which are hyaline vascular type and plasma cell type. Plasma cell type is frequently associated with systemic menifestations. Diagnosis is based on the histopatholgic findings. Treatment is surgical excision. A case of Catsleman's disease involving the parotid lymph node is presented and literatures are reviewed.

  • In 1999 and 2000, a rot of graft-cacti including Hylocereus trigonus (three-angled cactus), Gymnocalycium mihanovichii, and Chamaecereus silvestrii occurred in several greenhouses in major cactus-growing areas of Korea. Typical symptoms included a moist, light brown rot or a watery rot of the stems. A Colletotrichum sp. was isolated from the lesions. The fungus formed dark gray, dense or floccose colonies on potato dextrose agar, frequently forming many light pink acervuli often surrounded with setae. The hyaline, cylindrical conidia were one-celled with round ends. Appressoria were mostly semicircular or clavate. Thin-walled asci contained eight, one-celled, hyaline ascospores (biseriate in ascus). Ascopspores were strainht or curved, ellipsoidal or subcylindrical. Based on these characteristics, the fungus was identified as Glomerlla cingulata (anamorph : C. gloeosporioides). Wound inoculation of basal stems of the cactus by the mycelial plugs or conidia produced symptoms identical to those described above. Various cactus species were compared in susceptibility using stem disc inoculation. Cereus tetragonus, Eriocereus jusbertii, Myrtillocactus geomentrizans, and three-angled cacti from Mexico and Taiwan were susceptible, but C. peruvianus (Peruvian apple cactus) and Harrisia tortuosa not. This is the first report of G. cingulata causing stem rot of graft-cactus in Korea.

  • Gray mold caused by Botrytis cinerea was found on a carrot seedling in a greenhouse and a field at Daegwallryeong, Gangwon Province in 2007-2009. Symptoms included irregular, brown, blight, or chlorotic halo on leaves and petioles of the carrots. Fungal conidia were globose to subglobose or ellipsoid, hyaline or pale brown, nonseptate, one celled, $7.2-18.2{\times}4.5-11\;{\mu}m$ ($12.1{\times}8.3\;{\mu}m$) in size, and were formed on botryose heads. B. cinerea colonies were hyaline on PDA, and then turned gray and later changed dark gray or brown when spores appeared. The fungal growth stopped at $35^{\circ}C$, temperature range for proper growth was $15-25^{\circ}C$ on MEA and PDA. Carrots inoculated with $1{\times}10^5$ ml conidial suspension were incubated in a moist chamber at $25{\pm}1^{\circ}C$ for pathogenicity testing. Symptoms included irregular, brown, water-soaked rot on carrot roots and irregular, pale brown or dark brown, water-soaked rot on leaves. Symptoms were similar to the original symptoms under natural conditions. The pathogen was reisolated from diseased leaves, sliced roots, and whole roots after inoculation. As a result, this is the first report of carrot gray mold caused by B. cinerea in Korea.

  • Experiments were carried out to investigate Cd accumulation, elimination and cell response in juvenile rockfish (Sebastes schlegeli) exposed to sub-chronic dietary Cd (0, 0.5, 5, 25 and 125 mg/kg) for 60 days and depuration periods of 30 days. Cd accumulation in the kidney of cock fish increased with exposure periods and concentrations for the 60 days of dietary Cd exposure. After the end of the dietary Cd exposure, Cd accumulation values in the kidney were $52.9{\pm}9.94\;{\mu}g/g$ and $90.6{\pm}15.7\;{\mu}g/g$ for those exposed to 25 mg/kg and 125 mg/kg Cd, respectively. The accumulation factors increased with the exposure period in the kidney. Cd elimination in the kidney of rockfish did not vary significantly and remained constant after the cessation of the dietary Cd exposure. In the primary exposure periods, the effect of kidney tissue in the rockfish exposed to dietary Cd was observed the swelling of capillary of the glomerulus. In addition, there was also hydropic swelling within the pyknotic nuclei, some of hyaline droplet accumulation and the microvilli showed a positive reaction to alcian blue in the tubular cells. While exposure time and concentrations were increased, there was a lot of hyaline droplet accumulation and the microvilli showed a positive reaction to alcian blue in the tubular cells. Fused renal tubule and its necrosis were observed after 60 days at l25 mg/kg.

  • A rust disease occurred on Veratrum patulum in Deogyusan National Park, Jeollabukdo. The typical symptoms of the disease appeared as small, yellowish spots on leaves at first. The spots then turned brown, their edges rised slightly, and powdery mass of yellow or yellowish brown spores appeared on the lesions. Severely infected leaves blighted and eventually defoliated. Urediniospores were yellowish brown in color, globose, subglobose or ellipsoid in shape and $19{\sim}27\;{\times}\;17{\sim}24\;{\mu}m$ in size. Teliospores were brown in color, ellipsoid, ovate or oblong in shape and $19{\sim}36\;{\times}\;15{\sim}21\;{\mu}m$ in size, the apex mostly rounded, with hyaline or subhyaline conical papilla, the base rounded or attenuated, smooth. Pedicels hyaline or subhyaline, up to $38\;{\mu}m$ long. The causal fungus was identified as Uromyces veratri Schroeter based on mycological characteristics and host specificity.

  • Synovial chondromatosis developes by metaplasia of synovial cell into chondroblast in synovium of joint. It most commonly involves large joints such as knee or hip, and rarely occurs in shoulder joint. It is often difficult to be diagnosed preoperatively and surgical synovectomy is known to be effective treatment. We encountered a case of synovial chondromatosis with hyaline cartilage forming loose body in subacromial and subdeltoid synovium on the shoulder of a 44-year old female suffered by pain and discomfort. The authors report this case with a review of the relevant literature.
