We report herein a case of eosinophilic pustular follicultis in a 20-year-old man. The patient showed typical clinical picture with specific laboratory and histopathological findings of eosinophilic pustular folliculitis. The patient responded well to systemic administration of corticosteroid and dapsone.

OBJECTIVES: Cell adhesion molecules may play a role in integrating amnionic membrane. The objective of this study was to prove E-cadherin mRNA and proteins in cultured human amnionic cells. METHODS: We cultured amnionic cells from 4 women undergoing cesarean section without labor. E-cadherin was determined by immunohistochemistry and Western ligend blotting. To demonstrate E-cadherin mRNA, reverse transcription-polymerase chain reaction was performed. RESULTS: On immunohistochemistry, E-cadherin was abundantly showed on the cytoplasm of the cells. Western ligend blotting showed clear 120 kDa bands on four specimens, and relatively weak band on one specimen. Reverse transcription-polymerase chain reaction showed 432 BP bands. CONCLUSION: We proved E-cadherin and its mRNA by immunohistochemistry, Western ligend blotting and reverse transcription-polymerase chain reaction in cultured human amnionic cells.

Discoid semilunar cartilage is an abnormality in which the meniscus is discoid rather than semilunar, and first reported by Young of Glasgow in 1889. 13 cases of discoid semilunar cartilages which were experienced at the Department of Orthopedic Surgery, College of medicine, Seoul National University from Jan. 1956 till Aug. 1972 are reported with review of literature. 1) The incidence was remarkable higher in the male than in the female as 11 versus 2, and higher in the age group of second decade (Average 16.4 year old). 2) Most common site was lateral meniscus, and bilateral discoid meniscus were 3 cases. 3) 3 cases out of 13 cases had complicated rupture of semilunar cartilage, and one case had cyst of the meniscus. 4) Meniscectomy were performed in all cases with successful outcome.

Diagnostic radiologic studies for angiosarcoma are usually non-specific, but selective angiography is notablyexceptional, and there had been a few reports of CT or US featurs of hepatic or splenic angiosarcoma. We recentlyexperienced a case of hepatic and splenic angiosarcoma demonstrated by CT, US and selective angiogram in34-year0old man.

The ultraviolet radiation (UVR) is known to be a potent modulator of many host immune functions and the exposure of experimental animals to the inflammatory effects of UVR induces depressions in their ability to initiate and effectuate various types of cellular immune responses. In this study, the effects of UV-B (280 320 nm) radiation on resistance to a facultative intracellular bacterium, Listeria monocytogenes (LM), were examined at the cellular level. The numbers of cultivable LM recovered from the spleens of UV-B-irradiated mice were decreased at 2 days postinfection compared with those of untreated control mice. However, the acquired immunity, developed 7 days after immunization with streptomycin (SM)-sensitive LM, in either UV-irradiated, LPS- or IL-1-pretreated mice was less stronger than that developed in untreated, control mice. To elucidate the possible mechanisms underlying the observation that UVR did increase innate immunity but decreased acquired immunity of mice to the infection with LM, the effects of UVR of mice on the production of IFN-r by activated splenocytes and TNF-a by peritoneal macrophages were assessed. Activated splenocytes from UV-irradiated mice exhibited a reduced capacity to produce IFN-r and cultured peritoneal macrophages produced more TNF-a in the presence of LPS during 24 hours after UV radiation. Though TNF-r activity was not detected in the sera of LM-infected mice, intravenous LPS injection induced TNF-r production and UVR decreased TNF activity in sera obtained from LM-infected mice with LPS induction 9 days after irradiation. Although Ia-negative macrophages were predominant in the peritoneal macrophages from untreated control mice, the infection of mice with LM caused a marked increase in Ia expression on peritoneal macrophages. However, UVR resulted in decreased expression of Ia molecule on the peritoneal macrophages during the LM infection. These findings suggest that the dual effects of UVR on the innate and acquired immunity of mice to the LM infection may be associated with altered capacities of splenocytes and peritoneal macrophages of the mice to produce cytokines, in addition to decrease of la molecule expression on the macrophages.

Authors carried out experimental study on chemotherapy with oral administration of Dithiazanine iodide (D.I.) and Bithionol sulfoxide(B.S.) in rabbit clonorchiasis. And the following result was obtained. In change of the E.P.G (eggs per gram feces) by D.I. administration, it was rather increased in early stage of the administration than prior to administration, and thereafter decreased gradually. In the change of the C.S. worm body by D.I. administration, there was not only prominent change of supporting tissue but also the change of reproductive organ was found. In considering the wormicidal effect of D.I. from detecting rate of survival worms, the effect was slight in group of 100 mg(80 mg/kg) per day dosage, but the effects were very excellent and almost complete by proper times of administration in groups of 200 mg (130 mg/kg) per day or higher dosage. But the side effect and intoxication sign of D.I. were appearent in groups of 200 mg or higher dosage. By B.S. administration, E.P.G. was decreased gradually. In changes of the C.S. worm body by B.S. administration, prominent inhibitory chnnge was seen in egg formation ability. Slight wormicidal effect of B.S. was observed in groups of 140 mg (100 mg/kg) per day or higher dosage. Side effect and intoxication sign of B.S. were found little in groups of 140 mg or lesser dosage.

The influence of normal late pregnancy on insulin action and insulin secretion was studied in the Sprague-Dawley female rats. On 20th day after mating, intravenous glucose tolerance test(IVGTI) was performed in non pregnant control and pregnant rats. As results of IVGTT, glucose disappearance rate was not significantly different in both groups, but secretory response of insulin was significantly(p<0.05) increased in pregnant rat. And the ratio of insulin/ .glucose was significantly higher in pregnant rats, which means existence of insulin resistance. These insulin resistance was overcomed by increased secretory response of pancreatic insulin. Insulinogenic index( A insulin/glucose - 5 min) was highly significantly (r=0.62, p<0.01) correlated with progesterone concentration. Glycogen level and amounts of "C-glucose incorporated into glycogen after IVGTT were significantly(p<0. 05) decreased in the liver, but were not changed significantly in soleus. Glycogen synthase activity of soleus and liver was not differ significantly in the both groups. Insulin binding at varying concentrations of insulin to crude membrane of pregnant liver was not significantly different from control. In conclusions, although these pregnant rats were normal glucose tolerance due to increased secretory response of insulin, that was correlated with progesterone concentration, pregnant rat had insulin resistance. The mechanisms of insulin resistance were not related to defect of insulin binding phase and glycogen synthase, but suggest pre-receptor and/or postreceptor phase.
