Cutaneous protothecosis sometimes poses diagnostic and therapeutic problems. Isolation of the causative organism may not be successful and spores may be mistaken for other skin diseases unless the characteristic sporangia are detected in tissue sections. Because there are few cases, the optimal therapy is still being debated. On Liebs crystal violet staining we found charateristic purplish dots in Prototheca spores; these correspond to the amyloplasts or dense bodies found under electron microscopy. The isolated organisms were inhibited in vitro by itraconazole, amphotericin B, ketoconazole, and amorolfine and we were able to successfully treat two patients with itraconazole.

Tumor suppressive effect of dehydroepiandrosterone (DHEA) on the experimentally induced hepatocellular carcinoma was investigated, especially focusing on glutatione transferase and transglutaminase with aptosis in the carcinogenesis. The chemical hepatocarcinogenic procedure of Solt-Farber method was used on Sprague-Dawley rats. Experimental groups were divided into AA group treated by the standard Solt-Farber regimen of diethylnitrosamine (DEN) and 2-acetamidofluorene (AAF) and AD group treated with DHEA simultaneously with AAF and the AAD group treated by DHEA after treatment with AAF. Each group was divided by time sequence further into four subgroups, GI (8wk), G2 (16wk), G3 (28wk), and G4 (36wk). For neoplastic lesion, the immuno histochemical study with anti GSTP antibody was carried out, while the activity and expression of TGase was compared at the same time. The results were summarized as follows; GST-P positive foci detected in AD groups were significantly more suppressed by DHEA treatment than AA groups (P<0.05). AD groups. AD group showed higher activities of TGase than AA groups (P<0.05), which was confirmed by Western and Northern blot analysis. But the number of apoptotic bodies was not correlated with activity and expression of TGase in the nodule. These results suggest that the suppressive effect of DHEA on the murine hepatocellular carcinogenesis might be operating on the promotion process of carcinogenesis rather than regression process of transformed hyperplastic nodules.

This study was performed to investigate whethere there is cross-reactivity between Dirofilaria immitis and three intestinal nematodes of dogs. In ELISA, D. immitis-infected dog sera obtained at the 4th molting stage (9-11 weeks) and microfilaremic stage (25-30 weeks) were shown to be highly reactive with crude extract of T. canis. In immunoblotting, some antigenic fractions, 44, 57, 88, 100 kDa of crude extract of T. canis, were found to be positive reaction with sera of dogs infected with D. immitis. However, little or no cross-reaction were observed between sera of D. immitis-infected dogs and crude extract antigen of T. vulpis or A. caninum. These result suggest that there are partial cross reaction between sera of D. immitis-infected dogs and the antigen of T. canis.

Sinus histiocytosis with massive lymphadenopathy(SHML) is a benign, generally selflimited pseudolymphomatous disease that typically appears with cervical massive lymphaclenopathy. Extranodal involvement including skin occurs in the 28% of the cases. We report a case af SHML in 51 year-old male who had several, prominent firm masses ranging from 1-10cm in the cervical, axillary, inguinal areas and multiple, plum colored nodules and plaques in the face, trunk for about 10 years. The histopathological findings of cervical lymph node, facial nodule showed dense heavy infiltration of large histiocytes with abundant pale eosinophilic cytoplasm in the subcapsular and medullary sinuses of lymph node and dermis of skin. No atypical cells suggesting malignancy is seen in the infiltrates. The patient had been treated with combination of prednisolone and vinblasstine, but he expired 1 month later.

BACKGROUND: Flecainide is an antiarrhythmic agent that is used primarily in the treatment of cardiac arrhythmias. Some evidences also suggest that flecainide can participate in alveolar fluid clearance and inflammatory responses. This experiment was aimed to evaluate the effects of flecainide on sepsis induced acute lung injury in a rat model. METHODS: Rats were treated with subcutaneous infusion of saline or flecainide (0.1 or 0.2 mg/kg/hr) by a mini-osmotic pump. Subcutaneous infusion was started 3 hours before and continued until 8 hours after intraperitoneal injection of saline or endotoxin. Animals were sacrificed for analyses of severity of acute lung injury with wet to dry (W/D) ratio and lung injury score (LIS) in lung and inflammatory responses with level of leukocyte, polymorphonuclear neutrophils (PMNs) and inteleukin-8 (IL-8) in bronchoalveolar lavages fluid (BALF). RESULTS: Flecainide markedly improved dose dependently sepsis induced acute lung injury as analysed by W/D ratio (from 2.24 ± 0.11 to 1.76 ± 0.09, p < 0.05) and LIS (from 3 to 1, p < 0.05), and inflammatory response as determined by leukocyte (from 443 ± 127 to 229 ± 95, p < 0.05), PMNs (from 41.43 ± 17.63 to 2.43 ± 2.61, p < 0.05) and IL-8 (from 95.00 ± 15.28 to 40.00 ± 10.21, p < 0.05) in BALF. CONCLUSIONS: Flecanide improve sepsis induced acute lung injury in rats by controlling inflammatory responses.

We describe a case of cutaneous angiomyolipoma found in the ear lobe, that is not associated with tuberous sclerosis. The lesion developed on the youngest patient yet reported in the literature.

A study was made in the congenital anomalies in 137 babies born to 120 mothers with hydramnios, delivered at Ilsin Christian Hospital between Jan. 1st 1981 and Dec. 31th 1990. The results were as follows; 1) The incidence of hydramnios was 1.6/1000 deliveries, 120 cases in total 73, 129 deliveries. 137 infants was born and of these 71 (51.8%) had congenital anomalies. 2) Hydramnios was assiciated with a high incidence of prematurity and low birth weight infant. 3) The incience of multiple anomalies was 54.9% (39 out of 71 infants). The most common system involved with the congenital anomalies was the musculoskeletal system, 28.9% (39 cases out of 135) and the most frequent anomaly was anencephaly, 15 cases. 4) The perinatal mortality rate was 759/1000 total (104 cases) and of these 45 cases, 43.3% were associated with congenital anomalies. 53 of the live birth had congenital anomalies and of these 27 cases (50.9%) died in the neonatal period.

Psoriasis is characterized by disregulation of keratinocyte growth with profound epidermal hyperplasia. Keratinocyte hyperplasia in psoriasis may be expained in part by overproduction of growth factor, and by altered metabolism of the epidemal growth factor receptors (EGFR) in affected skin. The expression of epidermal growth f ictor receptor was investigated by Northern blot and slot-blot analysis of total RNA extrated from biopsies of normal skin and psoriatic lesions. In Northern blot analysis, EGFR-specific mRNA transcripts from psoriatic tissues demonstrated the specificity of hybridizarion with a EGFR mDNA probe. The size of EGFR mRNA transcript was 6.7kb in psoriasis lesions which showed no change of quality. In slot-blot analysis, the levels of EGFR mRNA in poriasis revealed a 1.2 fold to 4.1 fold elevation when compared to normal skin. EGFR were present in all epidermal layers by immunoperoxidase staining, whereas in normal skin they were primarily present in the stratum basalis. These results indicate that the increased expresion of the EGFR gene may be, in part, responsible for the hyperproliferation of the epider nis and that retained EGFR may reflect incomplet; abnormal differentiation in active porasis. This altered process of EGFR metabolism may be involved in the pathogenesis of psoriasis.
