PURPOSE: TGF-beta is a key regulator of epithelial-mesenchymal transition. Among the TGF-beta responses, cell migration is closely associated with the expression of matrix metalloproteinases (MMPs). Therefore, we determined which MMPs are regulated by TGF-beta and examined the TGF-beta signaling involved in this event, focusing on Src family tyrosine kinases (SFKs) METHODS: First we examined the expression of MMPs in rat lens explant culture treated with TGF-beta and LECs attached to the anterior capsules of patients with nuclear (N), anterior polar (AP) cataracts using RT-PCR and immunofluorescence staining. It was examined whether the expression of MMPs is regulated by SFKs. RESULTS: The study using RT-PCR and immunofluorescence staining showed the expression of MMP-2 and -14 in explants and the expression of MMP-14 LECs of AP cataracts. The expression of MMP-2 and -14 was blocked by PP2 in explants. Furthermore, the activated form of SFKs was observed in LECs of AP cataracts by immunofluorescence staining. CONCLUSIONS: We suggest a novel role of SFKs signaling in the expression of MMP-14 induced by TGF-beta.

We present herein 3 cases of early secondary syphilis with simultaneous primary syphilitic lesions. These cases developed primary syphilitic lesions four to six weeks after sexual contact and lasted six to ten weeks thereafter until the secondary syphilitic lesions appeared. All three patients showed a strong positive for the STS. Spirochetes were seen under dark field examination of the primary syphilitic lesions, Histopathologically, numerous plasma cells around capillaries and endothelial hyperplasia were seen in the dermis.

This study was designed to compare the level of medical utilization between the urban and rural areas of Korea and to explain the differences between the two regions. Data from the National Health Interview survey performed by the korean Institute of Health & social Affairs in 1992 were used for this study utilizing a sample size of 21,841 people. The level of medical utilization such as the number of physician visits and the number of hospital admissions was compared between the regions with ANOVA. Various determinants for medical use were also compared by univariate analysis. Statistical models which included enabling factors, predisposing factors, need factors and region were constructed for bivariate analysis in order to further elucidate the level of medical utilization. The results were as follows: 1. There was greater medical use, both in terms of physician visits and inpatient care in the rural areas in spite of insufficient health resources. The particular reasons for higher medical utilization in rural areas were attributed to a higher number of initial physician visits as well as a longer the length of stay per hospital admission. Therefore, indicators representing the degree of met need (utilization/need) showed no significant difference between rural and urban areas in spite of the fact that the medical need is larger in rural areas. 2. Use of public health facilities received a significant portion of physician visits in the rural area. The government's effort to enhance primary health care through health centers, health subcenters and the nurse practitioner's post in rural areas has contributed to the increase of access to medical care in the rural areas. 3. There were some differences in the socio-demographic characteristics between two regions; There were more elderly people over the age of 65; unstable marital status, less education and lower incomes also characterized the rural areas. Therefore, among rural people, there were more predisposing factors for medical use. Additionally, need factors such as poor self-reported health status and high morbidity level were also high in the rural area. 4. In contrast it was learned that, the supply of health resources was mostly concentrated in the urban areas except for public health facilities. Therefore, geographical access to medical care was lower in the rural area both in terms travel time and travel cost. 5. The coefficient of the region variable was insignificant in the regression model which controlled the supply factor only However, utilization was significantly higher in urban areas if the model included predisposing factors and need factors in addition to the supply factor. The results were interpreted as rural people have greater medical needs.

Purpose: To report six cases of exogenous fungal endophthalmitis developed after cataract surgery.Case summary: Over about 1 month, eight patients were referred to our hospital under suspicion of fungal endophthalmitis arose after cataract surgery. We performed vitrectomy and intraocular lens removal. We intraoperatively sampled the anterior chamber, vitreous cavity, or intraocular lens surface, and performed staining and culture tests. Before the culture test results were available, we commenced empirical treatment under suspicion of fungal endophthalmitis (based on the clinical features). Five eyes were male and three female (eight eyes of eight patients); the mean patient age was 64 years. The time from cataract surgery to the commencement of appropriate treatment ranged from 13 to 36 days (average 28 days). The culture tests revealed Fusarium species in six of the eight patients. At the 1-month postoperative follow-up of these six patients, the best-corrected visual acuities were 20/20 (one eye), 20/40 (two eyes), 20/50 (one eye), and 20/100 (two eyes). Conclusions Fungal endophthalmitis is very rare after cataract surgery but is associated with poor visual prognosis and requires long-term treatment. If fungal endophthalmitis is suspected, aggressive treatment with an appropriate selection of medication is important.
