  • A taxonomic survey of the dinoflagellate family Prorocentraceae Stein was conducted on 17 locations off the coast of Korea. This monograph is the result of the microscopic analyses. A total of eight species have been identified and described, of which Prorocentrum concavum Fukuyo is new record for Korea.

  • This report describes a case of pinnal fungal dermatitis caused by Arthroderma vanbreuseghemii in a Rex rabbit diagnosed by clinical signs, macro- and microscopic examination, molecular and phylogenetic analyses. This is the first description of natural A. vanbreuseghemii infection in rabbits in South Korea.

  • Cotyledon of Panax ginseng was cultured in the growth regulator-free Knudson C medium comprising only several kinds of mineral salts and sucrose. Shoot primordium or callus developed profusely from the cotyledonary tissue and finally plantlets were produced directly from the shoot primordium or indirectly through callus. Microscopic examination revealed that the epidermal cell as well as the mesophyll cell of the cotyledon became meristematic and divided, changing into multinucleate cell or multicellular body, eventually developing into either a shoot primordium or callus.

  • Oral mucosal lesions with a papillary or verrucous surface are a heterogenous group of conditions with widely varying clinical behaviour. The etiology is variable and includes infective, traumatic or neoplastic processes. The majority of these lesions are precanceous lesion. Therefore, a biopsy is required to establish a diagnosis and the microscopic examination must be coordinated with the clinical findings. This paper reviews the clinical features and significance of papillary or verrucous lesions.

  • Primary malignant fibrous histocytoma(MFH) of pleura is very rare. Upon microscopic examination, the tumor was characterized by storiform pattern of growth and intense, diffuse immunostaining for $\alpha$ l-antichymotripsin. We report a case of primary malignant pleural fibers histiocytoma with extension to lung, which was managed by complete excision of pleural mass and lobectomy with thoracoplasty.

  • Pityriasis rosea in a 2-month old pig is described. Lesions were confined to the abdomen and groin. They consisted of raised, erythematous papules with distinct borders. Microscopic examination of the lesions revealed a nonspecific dermatitis with acanthosis, moderate infiltration of mononuclear cells and eosinophils in the upper dermis. The known occurrence of the disease will help differentiate the condition from other dermatoses.

  • Nineteen cases of Albino rat having naturally occurred renal lesions were observed during the routine examination of a total of 240 cases. The lesions observed were focal suppurative nephritis (6 cases), acute nonsuppurative nephritis (3 cases), chronic interstitial nephritis (4 cases), nematode infection in pelvic epithelium (5 cases, in which one case was coincident with focal suppurative nephritis) and unilateral hydronephrosis (2 cases). Gross and microscopic findings for the lesions were described and discussed.

  • 300 extracts derived from 100 plants were tested for their potential to induce HL-60 cell differentiation using NBT assay and NSE/SE staining methods. Morphological changes from suspended to adherent state of the cells were also observed by microscopic examination. In result, 55 extracts induced cell differentiation into monocyte/macrophage lineage in the NBT and the NSE assay.

  • The report describes a case of natural E. ewingii infection confirmed by microscopic examination and molecular analyses in a domestic dog with acute lameness. After the diagnosis, the dog was successfully treated with oral doxycycline. To authors' knowledge, this is the first case report of natural E. ewingii infection in dogs in South Korea.
