T. verrucosum Infection has been reported for the first time in 1986 in Korea and has been increasing progressively. To evaluate the progress of clinical and histopathological change of dermatophytosis caused by T. verrucosum, inoculation study, using T. verrucosum isolated from infected human (human strain) and from infected cattle (cattle strain), was done in 24 male albino Hartley guinea pig. Their clinical and histopathological changes were evaluated. In addition, comparison for the growth rate between human strain and cattle strain on Sabouraud's glucose agar was made. The results were as follows: 1. Growth rate on Sabouraud's glucose agar: Cattle strain showed significantly more rapid growth rate than human strain on Sabouraud's glucose rate at 25℃ and 37℃. And cattle strain showed more rapid growth rate at 37℃ than 25℃. But human strain showed no significant difference of growth rate at both temperature. 2. Clinical findings: Initial erythema, scale and crust were developed about 8th after inoculation. All three findings reached maximum severity about 12th to 16th day and disappeared about 30th to 34th day after inoculation. There was no significant difference in progress of erythema, scale and crust between cattle strain and human strain. 3. Histopathological findings: Although mild acanthosis was noticed on the 3rd day after inoculation, the other findings including parakeratosis, intraepidermal abscess, spongiosis and vascular change, cellular infiltration were found on 9th day after inoculation. They reached maximum severity on the 12th day and lasted to the 25th day after inoculation. After that, all three findings were decreased gradually between 29th day and 33th day. On the PAS staining, hyphae and spores were found on the 6th day and disappeared on the 21th day after inoculation. 4. In trichophyton skin test, all of the 24 guinea pigs became positive within average 9.83±1.17 days These findings suggested that dermatophytosis caused by T.verrucosum induced rapid cell mediated immunity and contributed to rapid resolution of the lesion.

Vimentin is an intermediate filament protein normally expressed in mesenchymal cells, but the evidence of the aberrant expression of vimentin in epithelial cancer cells suggests that the vimentin expression might be related to local invasiveness and metastatic potential. There have been a few previous studies on the vimentin expression in human cervical carcinogenesis using in vivo and in vitro models. We examined the immunohistochemical vimentin expression in various squamous epithelial neoplasms of the uterine cervix, including the cervical intraepithelial neoplasia group (n=25), the microinvasive squamous cell carcinoma group (n=15), the invasive squamous cell carcinoma group (n=15) and the metastatic squamous cell carcinoma group (n=8). Vimentin positivity was significantly higher in the invasive than in the intraepithelial group, and in the cases with lymph node metastasis than in those without metastasis, suggesting a relationship between the vimentin expression and progression of the uterine cervical epithelial tumors.

BACKGROUND AND OBJECTIVES: Studies in patients with mitral valve prolapse syndrome (MVPS) have shown the coexistence of various forms of autonomic dysfunction, and so this is an area that requires further investigation. METHODS AND MATERIALS: The study group consisted of 65 patients (36 men and 29 women), aged 16 to 43 years (mean+/-SD, 28+/-8) with symptomatic, echocardiographically proven mitral valve prolapse (MVPS) who were free of other organic heart diseases and arrhythmias. In a prospective study, heart rate variability (HRV) indexes were calculated from 24-hour Holter recordings obtained during normal daily activity and plasma norepinephine was measured, and then these data were compared among the study group according to clinic heart rate (HR). RESULTS: The study group was divided into below 60 bpm (group 1: n=13), 60 - 80 bpm (group 2: n=36) and over 80 bpm (group 3: n=16) on the basis of clinic HR. These patient groups were matched with respect to age and gender. There were significant difference in SDNNIDX, rMSSD and pNN50 between these groups (p=0.005, 0.009 and 0.002 respectively), and these HRV measures correlated inversely with clinic HR (p<0.01). As clinic HR increased, there was a tendency for plasma norepinephrine concentration to also rise (p<0.05), but there was no statistical significant difference between these groups. CONCLUSION: Our data suggests that MVPS may have subgroups of HRV, reflecting cardiac autonomic modulation, according to clinic HR.
