Neuroleptic malignant syndrome is a rare, but potentially life-threatening adverse event associated with the use of neuroleptic agents. We describe the case of a 47-year-old schizophrenic woman who was treated with clozapine for years. The patient developed acute renal failure with pulmonary edema, and underwent mechanical ventilation and hemodialysis.

We experienced a case of submucosal gastric actinomycosis, presenting as bleeding. The 65-year-old woman had a symptom of epigastric pain, without any other intra-abdominal disease entity. A gastrofiberscopic study demonstrated a submucosal mass lesion with bleeding at the fundus. Because of the bleeding, laparotomy was undertaken, and a abscess containing a large mass was found at the gastric fundus, and total gastrectomy undertaken. Histological examination revealed a giant acute ulcer with a submucosal abscess due to actinomycosis. Because of its rarity, submucosal gastric actinomycosis is an entity overlooked by most surgeons. We report upon this case of submucosal gastric actinomycosis and include a review of the literature.

We report a case of hereditary trichilemmal cyst with proliferating trichilemmal tumor in a 64-year-oid man, who has generalized 157, variable sized firm cutaneous nodules for 40 years. The cystic nodules are chiefly located on the scalp and trunk which showed characteristic histopathologieal findings of trichilemmal cyst and proliferating trichilemmal tumors. His son also has multiple trichilemmal cysts and his mother seems to have had clinically similar lesions. The patient and his son were treated with surgical excision and therapeutic trial of oral isotretinoin for 2 months. Isotretionoin was ineffective in the patient, but the lesions of his son were decreased in size.

We report, a 1-day-old male with congenital cutaneous candidiasis who had generalized erythematous papules and pustules on the whole body including palms and soles from birth. At 5th month of pregnancy, his mother had a history of vaginal candidiasis for a month KOH mount of pus from pustules of several different sites showed budding spores and pseudohrphae and fungus culture revealed the growth of Candida albicans We believe this to he the first documented case of congenital cutaneous candidiasis in Korean literature.

The ultimate aim of periodontal treatment is periodontal regeneration, which necessiates the regeneration of bone tissues. This paper investigated the effect of growth factor on bone cells. Platelet-derived growth factor(PDGF) is the one of the polypeptide growth factor that has been reported as a biological mediator which regulates activities of the cell proliferation, migration and metabolism of undifferentiated mesenchymal cells. The purpose of this study is to evaluate the effects of PDGF on bone nodule formation and ALP activity of MC3T3-E1 cells. Cells were seeded at 1x10(5)cells/well in alpha-modified eagle medium containing 10% fetal bovine serum, 10ml beta-glycerophosphate and 50microgram/ml of ascorbic acid. PDGF 0, 0.1, 1, 10ng/ml were added to the cells at a confluent state and cultured for 3, 7, 14, 21, 28 days. We examined bone nodule formation and alkaline phosphatase activity. The results were as follows: There were bone nodule formation at day 21 both in control and all the experimental groups, and at day 28, all the experimental groups showed much more bone nodules than control groups. Compared to control-1 group, ALP activity was increased in PDGF 0.1ng/ml group and was decreased in 1,10ng/ml PDGF treated groups.(P< 0.05, P< 0.01) Compared to control-2, ALP activity was decreased in all the experimental groups except PDGF 0.1ng/ml in 21 day group. In the time-response effect, ALP activity was increased by the day 14 in all the experimental groups and thereafter ALP activity was decreased.(P<0.05, P< 0.01) In the dose-response effect, ALP activity was decreased as the dose of PDGF was increased, and after 21 day ALP activity was lowest in 1ng/ml group, ALP activity was highest in the day 7 in control group and 0.1ng/ml, 14 day experimental group. In conclusion, PDGF is considered more effective in the proliferation than differentiation of osteoblast-like cells, and it may be useful to study the combined effect of PDGF and other growth factors on osteoblast-like cells.

Polypeptide growth factors belong to a class of potent biologic mediators which regulate cell differentiation, proliferation, migration and metabolism. IGF-I is polypeptides secreted by skeletal cells and is considered as regulators of bone formation. The purpose of this study is to evaluate the effects of IGF-I on bone nodule formation and alkaline phosphatase activity of MC3T3-E1 cells. MC3T3-E1 cells were seeded at 1x10(4) cells/well, 1x10(5) cells/well in alpha-modified Eagle medium containing 10% fetal bovine serum, 10 mM beta-glycerophosphate and 50microgram/ml of ascorbic acid. Before 48 hours of indicated time, medium were changed with serum free medium. After 24 hours, 0.1, 1, 10 ng/ml IGF-I were added to the cells and cultured for 3, 7, 14, 21, 28 days. And histochemical analysis was done and ALP activity was measured and was expressed as nmol/min/mg of protein. The bone nodule formation in MC3T3-E1 cells of IGF-I was seen at 21, 28 days, but there were no difference between control group and experimental groups. The ALP activity decreased when it is compare to control 2 group except for 1 ng/ml, 10 ng/ml IGF-I of 21-day-groups and 1 ng/ml IGF-I of 28-day-groups. Dose response effects of IGF-I of ALP activity in MC3T3-E1 cells were seen the highest ALP activity at 1ng/ml until 21days and the highest ALP activity at 10 ng/ml of 28 daygroups. The peak times were seen at 7-day group, 14-day group on control group and experimental group respectively, and 1 ng/ml group was the highest ALP activity. From the above results, IGF-I was not seen notable effect on bone nodule formation and decreased ALP activity of MC3T3-E1 cells but the use of IGF-I to mediate biological stimulation of MC3T3-E1 cells shows promise for future therapeutic application.

PURPOSE: To assess the usefulness of breath-hold fast MR imaging of liver with fat suppression (FS) by application of chemical saturation technique in the diagnosis of regional fatty changed suspected in sonography. MATERIALS AND METHODS: Thirteen patients who had focal lesions with diffuse, homogeneous signal changes after FS through chemical saturation technique without additional changes of imaging parameter during MR imaging of liver were selected. T1-weighed fast low-angle shot and T2-weighted turbo spin-echo sequences were obtained with or without FS during each single breath-holding session. Subjective changes of signal intensity between the pre-FS and the FS images were compared with the sonographic findings in each lesion. RESULTS: Seven lesions of decreased signal intensity after FS on T1 or T2-weighted images, including three lesions only at FS T1 images, were regarded as focal fat infiltration. All seven lesions had compatible sonographic findings as homogenously echogenic areas. Another six lesions of subjectively increased signal intensity including two lesions only at FS T2 images were regarded as focal fat sparing. All six lesions had sonographic findings as homogenous echo poor areas suggesting focal fat sparing. In cases regarded as fat infiltration, score changes were more prominent at FS T1 images than FS T2 images(p=0.0002). In cases regarded as fat sparing, score changes were more prominent at FS T2 images than FS T1 images(p=0.042). CONCLUSION: Breath-hold fast T1 and T2-weighted MR imaging with and without chemical saturation pre-pulse may be sufficient for characterization of regional fatty changes in the different ferential diagnosis of focal hepatic lesion found at sonography.
