A 60-year-old male complained of headache, nasal discharge, and diplopia for over one month with a history of left upper molar extraction, and he had recently experienced severe discharge of purulent exudate from his left antrum. Under the diagnosis of maxillary sinusitis, the Caldwell-Luc operation was performed, and several fragments of amorphous white mucoroid materials were removed. In the histological observation, sinus mucosa was relatively well preserved, but showed diffuse infiltration with eosinophilic polymorphonuclears. Huge molds of mucormycosis were associated with the surface of mucosa. He was treated with amphotericin-B deoxycholate, resulting in the uneventful healing of the antral lesion. The current case of antral mucormycosis was very rare but effectively treated by surgical removal of antral mucosa and the following antibiotic therapy for the strong inhabitants of fungal molds. We also presumed that the patient was superinfected with commensal fungus of mucormycosis during broad spectrum antibiotic therapy for the previous dental infection.

인공산성비의 pH가 낮아질수록 고추씨의 발아에 걸리는 시간은 단축되었으며 발아율은 향상되었으나 어린 싹에게는 매우 치명적인 영향을 미쳤다. 어린 고추모는 이미 자란 식물체에 비하여 산성비에 훨신 더 민감하게 작용하였다. 산성비의 전형적인 가시피해증상은 잎에 나타나는 흰색 반점이었으며, 빗물의 pH가 낮을수록 더 빨리 더 심하게 나타났다. 고추의 역병은 일반적으로 인공산성비 처리구에서 대조구보다 빨리 발병하였으나, 인공산성비의 pH가 아주 낮을 때는 다른 처리구에 비하여 오히려 병의 발생이 줄어들었다. 인공산성비 처리중에 역병을 접종하였을 때는 처리 전에 접종하였을 때보다 병이 더 빨리, 더 심하게 나타났다. 역병의 발생이 가장 심했던 것은 역병의 접종시기와는 관계없이 pH 4.0 또는 4.5인 빗물을 처리하였을 때였다.

Purpose: Livedo vasculitis is recurrent painful ulceration of the feet, ankles and legs characterized by purpuric papules and plaques that undergo superficial necrosis and healing with residual white atrophic scars (atrophie blanche). The typical histopathologic findings of livedo vasculitis are characterized by endothelial proliferation and hyaline degeneration along with thrombosis of dermal vessels. Standard therapeutic strategies for treatment of livedo vasculitis are usually on the basis of rheologic, anti-inflammatory or immnosuppressive treatments, a aspirin, dipyridamole, glucocorticosteroids, pentoxyfylline, or high-dose intravenous immunoglobulin are often ineffective or partially effective. Methods: We report a case of 24-year-old male patient with livedo vasculitis on the ankles and dorsal surfaces of both feet. Results: The lesion that had been unresponsive to medical treatment were successfully healed with complete debridement and skin grafting without recurrences. Conclusion: Surgical treatment can be one of the therapeutic choice in Livedo vasculitis.

Alveolar soft part sarcoma (ASPS) with skull and brain metastases is extremely rare. A 53-year-old patient diagnosed as skull metastasis of ASPS visited our clinic complaining of an outgrowing scalp mass in spite of radiation therapy. Past medical history revealed that the patient had been diagnosed and treated for ASPS of the thigh 4 years ago. Magnetic resonance imaging revealed a hyperintense ovoid mass on the T2-weighted image, an isointense on the T1-weighted image, and a homogeneous enhanced mass with gadolinium. Another small-sized enhanced mass with mild peritumoral swelling was found at the deep white matter of the left frontal lobe. A gross total resection of the skull lesion with cranioplasty was performed for the surgical defect. A histologic examination of the specimens revealed metastatic ASPS involving the skull. Surgery with a total removal of the lesions may be effective for improving a patient's symptoms especially from neurological dysfunction.

This studies was carried out to investigate a process of formation for the granulomatous lesions in the liver and the haematological variation with the lapse of time after infection of Capillaria hepatica in dogs. Twelve crossbred puppies, about 3 months of age and 2-3 kg of body weight, were administered with 2,000 Capillaria hepatica infective eggs. Every four puppies was sacrificed on 1 week, 3 weeks and 5 weeks after infection, respectively. Although no marked clinical sign was noticed, total leukocyte values were increased peak on 1 week, and then reduced gradually on 3 weeks and 5 weeks after infection. Absolute differential counts of neutrophils and lymphocytes were significantly increased on 1, 3 and 5 weeks after infection. Absolute differential counts of monocytes and eosinophils were trend to increase during the experimental periods. On grossly findings, liver congestions were observed in all infected puppies, and a few white specks were scattered under liver capsule in one puppy on 3 weeks and two puppies on 5 weeks after infection. On microscopic findings, many fresh larvae were observed in the liver tissues in one puppy on 1 week after infection. A worm was decayed and only a portion of cuticle was shown in one puppy on 3 weeks after infection. Around the central necrotic material, the layers of thick macrophages with a few giant cells and lymphocytes with fibrous connective tissues were consisted the granulomatous lesions on 5 weeks after infection.

A total of 33 isolates of Colletotrichum species obtained from pepper, apple, and strawberry in 2001 and 2002 were identified based on mycological characteristics, responses to fungicides carbendazim and the mixture of carbendazim and diethofencarb, and nucleotide sequence analysis of internal transcribed spacer (ITS) regionMost of the Colletotrichum isolates from pepper could be identified as C. acutatum. The pepper isolates produced grey white mycelia that gradually changed to dark gray. The conidia were variable in size, and almost cylindrical in shape with at least one rounded end. They could grow on PDA amended with carbendazim or with the mixture of carbendazim and diethofencarb at $10{\mu}g/ml$, to which the isolates from apple and strawberry were very sensitive. A part of the ITS regions from the Colletotrichum isolates was amplified with the specific primers designed for C. acutatum (Ca1-1) or C. gloeosporioides (Cg1-3). A primer pair of Ca1-1 and a universal primer (ITS4) amplified a 496-bp DNA fragment from all of the pepper isolates examined and one apple isolate. Taken together, it is conclusive that the Colletotrichum isolates causing the typical lesion of anthracnose on pepper fruits are C. acutatum.

Occurrences of diseased sweet flag (Acorus calamus L. var. asiaticus) were found in Chonju and Buan Province, on August 2002. The typical symptoms of the disease affected the leaves, pods, and collar of the infected plants. The leaves or pods became darker brown, then dry rotted, and white fluffy mycelia formed on the lesion. The collar, of the infected plants, formed black spot. The spores grew rapidly on PDA medium. Pathogenic fungi have not been identified clearly, as of yet. These fungi were formed from developed spores, as well as, undeveloped spores. These fungi suggest that Fusarium sp. and Rhizoctonia sp.. The range of temperatures were tested from 5$^{\circ}C$ to 35$^{\circ}C$ for mycelial growth. The optimum temperature for growth was 3$0^{\circ}C$. This is the first report on the fungus disease of sweet flag by some pathogens, in Korea. We would like to do further research for single spore isolation, pathogenity, and characterization of fungi.

A 6-year-old spayed female American Cocker Spaniel presented with episcleritis in the right and then the left eye (OS) at eight month interval. Repeated intralesional triamcinolone acetonide was administered subconjunctivally to both eyes (OU). During this period, scleral ectasia was revealed on ocular funduscopy OS and then confirmed on ultrasonography and computed tomography. A year later, conjunctival hyperemia occurred around remnant triamcinolone particles and was treated by resection of these particles in the OU. A recurrence of episcleritis, which did not regress, required repeated triamcinolone subconjunctival injections four months later in the OU. Four months after these injections OU, the dog was presented with bilateral conjunctival mass, which had developed over the previous month. The round-shaped masses with diameters of 1 cm were surgically resected from exposed scleral ectasia lesion of thin and bulging scleral surface in the OU. The cross-section of both masses showed a white-colored accumulation at the center and triamcinolone induced granulomas enclosing necrotic tissue were confirmed by impression cytology and histopathological examination.

일광망막병증은 드물지만 일반적으로 잘 알려진 황반질환이며 이는 직접적인 태양 관찰로 인해 일어난다. 21세 남자가 단안 망원경을 이용하여 좌안으로 약 30초간 태양을 관찰하고 약 48시간 후 시력저하와 중심암점을 호소하였다. 그로부터 약 8개월 후 중심시력은 1.0에서 0.1로 저하되었고 안저검사에서 황백색의 점상 침착물이 관찰되었고 형광안저 촬영에서 망막색소상피의 결손으로 인한 창문 결손이 좌안 중심와에 나타났다. 시야검사에서는 중심 암점이 관찰되었고 시력저하는 빛에 노출된 후 1년이 지난 후에도 지속되었다.
