The systemic lupus erythematosus is a self-perpetuating disease with multisystem involvement, i.e.; skin, kidney, serous membrane, nervous system and other organs. The mortality in SLE is determined primarily by the extent of renal involvement and the degree of immunosuppression resulting from the therapy. We experienced two cases of lupus nephritis in SLE with clinical, serologic, immunologic and pathologic evaluations. Renal biopsy revealed focal and segmental proliferative glomerulonephritis and mesangial proliferative glomerulonephritis. Both patients have been improving with prednisolone on follow-up studies.

The current study was performed to investigate the influence of acidosis on focal cerebral ischemia in view of morphometric assay and neuropathological examination. The acidosis was induced by increment of halothane concentration and by decreasing respiratory rate. The mean pH were 7.423+/-0.012 in control group and 7.184+/-0.038 in acidosis group. Twenty-four hours after MCA occlusion(MCAO), neutral red staining and perfusion fixation was performed. The ischemic area was measured and morphometric analysis was undertaken. In acidosis group, the infarct area was 25.23+/-4.78% of the total cerebral area;in control group, the infarct area was 27.69+/-4.05%. The histopathological findings were examined under light microscopy, in which the field scanning was carried out from the midline by 0.5mm interval at cortical and basal ganglia levels. These results indicated that although there was no satistically significant difference in infarct area between acidosis and control group, increased acidosis aggravated the extent of histopathologic ischemic neuronal damage.

This study was done to report the epidemiologic characteristics of medical retirement from the Republic of Korea (ROK) Army due to visual impairment and to suggest a practical screening system for the draft. The medical records of 423 eyes of 301 patients who retired from the ROK Army due to visual impairment were reviewed retrospectively between January 2010 and December 2014. The patients were grouped by the presence of trauma, and each group was subdivided by military rank. We analyzed demographic and ophthalmic data, including the etiology of ophthalmologic disease. The etiology was classified into 5 anatomical categories (ocular surface, lens, retina, optic nerve and extraocular visual pathway, and extraocular muscle and orbit), which were then subdivided into the type of disease. The mean age was 24.5 years, and non-traumatic mechanisms accounted for 81.1% (343/423 eyes) of medical retirements. Visual acuity was better in patients without trauma. In enlisted soldiers, disease in the optic nerve and extraocular visual pathway was the most common anatomical category (40.5%), and primary open angle glaucoma (30.8%), retinal dystrophy (18.3%), congenital cataract (14.5%), and retinal detachment (9.7%) were the four most common diseases. Most medical retirements due to visual impairment resulted from non-traumatic mechanisms, even though patients were young. The fundus examination and visual field test would be more useful tools than a conventional vision test for large-scale draft screening for the most common two disease types: primary open angle glaucoma and retinal dystrophy.

In Korea, Kerion celsi caused by T. verrucosum was first reported by Kim et al in the Honam province in 1986. Since then three mare cases have been reported in the Young Nam province. Herein present a case of kerion celsi caused by T. verrucosum from Chungcheong province. The patient, a 7-year old female, showed a 4x 4cm sized, oval, yellow crusted and boggy patch with alopecia on the scalp. She was living on a farm in a rural area of Chungcheong province. Cows on the farm also exhibited similar skin lesions on the buttock. The same T. verrucosum was identified by a characteristic colony morphology on Sabourauds dextrose agar and chains of chlamydoconidia with mycologic stain from scales of lesions of patient and cows. This skin lesion was successfully treated with griseofulvin.

A polymerase chain reaction (PCR) method for detection of the pathogenic Yersinia pestis from other Yersinia spp. was developed. Five Y. pestis strains, ninety-two other Yersinia species and twenty-four Enterobacteriaceae strains were collected in Korea and from other countries. Oligonucleotide primers were designed from pathogenic gene of antiphagocytic protein capsule gene (fra 1) and plasminogen activator gene (pla). The 428 bp DNA fragment was amplified from five Y. pestis which contained the fra I gene. No product was amplified from other Yersinia species and other strains of the Enterobacteriaceae. The 439 bp DNA fragment was amplified from three K pestis which contained the pla gene. No product was amplified from two Y. pestis, other Yersinia species and other strains of the Enterobacteriaceae. These showed that the designed primers were specific for detection of Y. pestis among other Yersinia species and Enterobacteriaceae strains. Amplification was successful whether the template was derived from purified DNA or from aliquots of boiled bacterial suspension. The detection limits were 100 pg of DNA and 100 colony forming units (CFU) for fra I and 100 pg DNA and 10 CFU for pla, respectively. Our results prove that the PCR method using specific primers for Y. pestis is a rapid and convenient procedure for routine clinical detection and identification of Y. pestis.

BACKGROUND: To study the prognosis of patients with lung cancer, many investigators have reported the methods to detect cell proliferation in tissues including PCNA, thymidine autoradiography, flow cytometry and Ki-67. PCNA, also known as cyclin, is a cell related nuclear protein with 36KD intranuclear polypeptide that is maximally elevated in S phase of proliferating cells. In this study, PCNA was identified by paraffin-embedding tissue using immunohistochemistry which has an advantage of simplicity and maintenance of tissue architecture. The variation of PCNA expression is known to be related with proliferating fraction, histologic type, anatomic(TNM) stage, degree of cell differentiation, S-phase fraction and survival rate. We analyzed the correlation between PCNA expression and S-phase fraction, survival. METHODS: To investigate expression of PCNA in primary lung cancer, we used immunohistochemical stain to paraffin-embedded sections of 57 resected primary non-small cell lung cancer specimen and the results were analyzed according to the cell type, cell differentiation, TNM stage, S-phase fraction and survival. RESULTS: PCNA expression was dMded into five group according to degree of staging(-, +, ++, +++,++++). Squamous cell type showed high positivity than in adenocarcinoma. Nonsignificant difference related to TNM stage was noticed. Nonsignificant difference related to degree of cell differentiation was noticed. S-phase fraction was increased wit advance of PCNA positivity, but t could not reach the statistic significance. The 2 year survival rate and median survival time were -50% 13 months, +75% 41.3 months, ++73% 33.6 months, +++67% 29.0 months, ++++25% 9 months with statistic significance (P<0.05, Kaplan-Meier, generalized Wilcox). CONCLUSION: From this study. PCNA expression was high positive n squamous cell cancer. And, there was no relationship between PCNA positivity and TNM stage, cellular differentiation or S-phase fraction. But, the patients with high positive PCNA staining showed poor survival rate than the patients with lower positive PCNA. It was concluded that PCNA immunostaining is a simple and useful method for survival prediction in paraffin embedded tissue of non-small cell lung cancer.
