We report three cases of rat mite dermatitis caused by Ornithonysus bacoti(Hirst, 1913), commonly referred to it as the tropicalrat mite. The first case, a 26-year old female had multiple pinhead sized vesicles with peripheral erythematous macule on the upper arms. The second case, a 34-year-old femal had multiple variable sized vesicles with erythematous base on the extremeties. The third case, a 43-year old male had multiple erythematous macules and papules with central punctum on the trunl: and extremities. Histopathologic sections from lesions of the first and second patient showed moderate perivascular lymphahistiocytic infiltration intermingled with some eosinophils. Causative mites, Ornithonyssus bacoti, female were collected around the skin lesion in rase 1, from the house dust in case 2 and furniture in case 3.

5.Ocular Manifestations of Patients with Rheumatic Disease and Dry Eye Symptom.
Journal of the Korean Ophthalmological Society 2002;43(10):1847-1851
PURPOSE: To evaluate the ocular manifestations of patients with rheumatic disease and dry eye symptom. METHODS: We analized the results of ocular examinations and complications of 78 rheumatoid disease patients who were refered for dry eye symptom from the general medicine from 1998, May to 1999, May. RESULTS: Ocular complications were seen in 47 patients (60.3%). Keratoconjunctivitis sicca was the most common ocular finding (48.7%). Other lesions were episcleritis, scleritis, peripheral corneal erosion, marginal keratitis, stromal corneal opacity, and so on. Thirty six patients (46.2%) showed sero-positivity for RA, ANA or CRP. The result was 6.87+/-4.44 mm (mean+/-standard deviation) in Schirmer test,6.64+/-2.27 sec in Tear Film Break Up Time (TBUT). Among sero-positive patients, Schirmer test was 5.46+/-4.05 mm and TBUT was 5.64+/-2.38 sec, while among sero-negatives the result was 8.21+/-4.33 mm, 7.40+/-1.89 sec respectively. It was statistically significant (P< 0.05). Schirmer test was 4.60+/-3.55 mm in RA positive, 2.50+/-1.60 mm in RA and ANA positive, 7.35+/-4.92 mm in CRP positive. TBUT was 5.57+/-2.39 sec, 4.00+/-1.31 sec, 5.69+/-2.04 sec in each group. CONCLUSIONS: Ocular complications were increased in rheumatoid patients, especially with sero-positive for RA, ANA or CRP. The results of Schirmer test and TBUT were most decreased in patients with RA and ANA positivity.

STUDY DESIGN: A retrospective analysis of 166 patients was undertaken to observe radiologically the changes of adjacent segments at follow-up more than three years after lumbar fusion. OBJECTIVES: The purpose of this study is to analyse the changes of adjacent segments and to correlate these changes to the length of using level and to the degree of deviation from physiologic lumbar lordosis. The authors also correlate these radiologic changes to the clinical symptoms. MATERIALS AND METHODS: In simple x-ray, authors observed traction spur, disc space narrowing, endplate sclerosis and vacuum phenomenon of adjacent segments. Authors used Gelb's criteria in segmental lordosis angle(SLA) and Katz's classification in clinical results. RESULTS: The average age was 49.6 years old and the average follow-up period was 57.2 months(4 years and 9.2 months). We observed radiologically the traction spurs in 35 cases(21.1%), end-plate sclerosis in 32 cases(19.3%), disc space narrowing in 33 cases(19.9%) and the vacuum phenomenon in 10 cases(6.0%). The numbers of fusion segments and the degree of unphysiologic segmental lordosis angle in fusion segments were related with the frequency and degree of changes of adjacent segments(P<0.05). The clinical results showed satisfaction in 142 cases(85.5%), unsatisfaction in 24 cases(14.5%) and low back pain in 24 cases(14.5%), leg pain in 11 cases(6.6%) and extension of fusion level in 4 cases(2.4%). In low back pain patients more than two kinds of radiological changes were frequently observed than the patients without low back pain(P<0.05). CONCLUSIONS: The radiological changes of adjacent segments were more frequently observed in long fusion and in fusion with unphysiologic lumbar lordosis angle. And these changes are frequently associated with low back pain. Thus long fusion and fusion with unphysiologic lumbar lordosis angle should be avoided if possible.

An epidemiological study on brugian filariasis was carried out in endemic areas including Cheju Island in Korea, with a brief review of literatures.The results showed that the incidence among residents has remarkably decreased in Cheju Island, which was the main endemic area. Reviewing available informations on the prevalence of filariasis reported in recent years and also judging from the present socio-economic conditions which enable people to practice personal protection against mosquitos, it can be said with confidence that filariasis has almost disappeared from Cheju Island and inland areas. The disease is considered to remain at a low level of endemicity in Hugsan Islands. Certainly mass diethylcarbamazine (DEC) treatment carried out in Cheju Island in the 1960s and 1970s and remarkable economic growth followed by improved living standard and altered life-style of inhabitants could all have combined effects on the disappearance of this mosquito-borne diseae in this island. If the present trends go on, the possibility of resurgence of filariasis in Cheju Island is hardly postulated.

Cancer is considered to occur through abnormal growth and differentiation processes, in which oncogenes and tumor suppressor genes are deeply related. Cellular responses to DNA-damaging agents are believed to be critical determinants of human tumorigenesis. Cell cycle arrests and DNA repair following DNA damage require the coordination of multiple gene products that, as a whole, serve to maintain the integrity of the genome. Within the cell cycle, both G1-S and G2-M phase transitions are under constant surveillance by checkpoint genes for the protection of cells from either exogenous or endogenous DNA-damaging agents. p53 tumor suppressor gene mediates cell cycle perturbations in response to DNA damage, and play a role in cell death, genetic stability, and cancer susceptibility. Recently, gene therapy with p53 tumor suppressor gene is expected as a new effective therapeutic strategy in many kinds of cancer. By using retroviral vector system, we transduced p53 tumor suppressor gene into human osteosarcoma cells, and analysed its growth suppression and apoptosis inducing effects. Combined effects of p53 gene therapy with chemotherapeutic agent or radiation were also analysed. Titer of ecotrophic p53 retrovirus was 5.0x10/ml, and that of amphotrophic p53 retrovirus was 2.0x10/ml when NIH3T3 cells were used as target cells. Human osteosarcoma cells infected with amphotrophic p53 retroviruses showed increased p21waf1 gene expression, which acts as a major cyclin-dependent kinase inhibitor in DNA damage responses. In normal DMEM media, human skin fibroblasts infected with amphotrophic p53wt retroviruses showed very slow growing (1.7 fold increase in doubling time) and very low saturation density (50% decrease in cell density). In media containing chemotherapeutic agent, human osteosarcoma cells infected with p53wt retroviruses died rapidly; 75% of them died within 4 days and all of them died within 10 days of incubation with chemotherapeutic agent. Their DNAs were extracted and electrophoresed in agarose gel, and we identified DNA ladders characteristic of apoptotic cell death. When human osteosarcoma cells infected with p53 retroviruses were irradiated with ultraviolet light, more than 95% of cancer cells died within 1 day; whereas mock infected cells showed only less than 5% of cell death. These findings suggest that retroviral vector mediated p53 tumor suppressor gene transfer into cancer cells can suppress tumor cell growth and decrease tumor cell density effectively. These findings also suggest that effective induction of tumor cell apoptosis can be obtained when p53 gene therapy is used in combination with chemotherapy or radiotherapy.

The term malignant mesenchymoma has been applied to those tumors of the soft tissue of mesenchymal origin which are composed of tumor cells differentiating into two or more unrelated malignant forms in addition to the fibrosarcomatous element. Recently authors experienced a case of malignant mesenchymoma in the right axillary area. Microscopically the sarcoma revealed multiple pattern of differentiation, including liposarcoma, malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma and rhabdomyoblastoma. The presence of rhabdomyblastic cells were proved by immunochemical study utilizing desmin. This patient was treated with surgical excision and radiation.
