PURPOSE: Platinum coordination complex (cisplatin) has been currently used as one of the most effective compound in the treatment of various solid tumors. However, its use has been limited by severe side effects such as renal toxicity. Our platinum-based drug discovery program has been aimed at developing drugs capable of diminishing toxicity and selective cytotoxicity. MATERIALS AND METHODS: A new series of highly water soluble platinum (II) complexes Pt (II) [1,3-Bis (phenylthio) propane) (trans-l-1,2-diaminocyclohexane) (PC-1) and Pt (II) [1,3-Bis-(phenylthio) (propane)]-1,2-diaminocyclohexane (PC-2) were synthesized and characterized by their elemental analysis and by various spectroscopic techniques [infrared (.IR), ""C-nuclear magnetic resonance (NMR)]. In vitro antitumor activity and nephrotoxi -cities of new Pt (II) complexes were tested against MKN-45 human gastric cancer cell- lines and normal kidney cells using colorimetric MTT[3-(4,5-dimethyl thiazol-2-yl)-2,5- diphenyl tetrazolium bromide] assay for cell survival and proliferation. RESULTS: PC-1 showed activity against MKN-45/P and MKN-45/CDDP human gastric adenocarcinoma cells, and the antitumor activity of this compound was comparable or superior to that of PC-2 and cisplatin. The nephrotoxicity of PC-1 and PC-2 were found quite less than that of cisplatin using MTT, [H] thymidine uptake and glucose consumption tests in rabbit proximal tubule cells, human kidney cortical cells and human renal cortical tissues. CONCLUSION: Based on these results, this novel platinum (II) complex compound (PC-1) represent a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low nephrotoxicity.

We report a case of eosinophilic pustular folliculitis (EPF) with associated plantar lesions in a 45-year-old man. Exarnination of the skin disclosed an erythematous patch, approximstely 3 x 5cm, on the left cheek, which contained discrete and confluent pspulopustules and scaly circinated vesicular patch on the right foot. Histologic examination of a biopsy specirnen from the left cheek revealed the hair follicles and the sebaceous glands are infiltrated mainly by eosinophils and by some mononuclear and neutrophils. Histologic examination of a biopsy specimen from the right foot revealed a vesicle extending from the subcorneal portion to the lower epidermis, which was filled with neutrophils and a small number of eosinophils.

BACKGROUNDS: Korean Activities of Daily Living(K-ADL) scale was developed to measure the elderly function. The aim of the present study was to establish the validity and reliability of Korean Activities of Daily Living(K-ADL) scale. METHODS: Clinical validity and convergent validity was tested. Reliability was tested by internal consistency(Cronbach's alpha), two weeks test-retest method, and interrator correlation. RESULTS: Cronbach's alpha was 0.937. 2 weeks test-retest correlations in all 7 items were higher than 7.0. Interrator agreements were high in all 7 items(h=0.86~1.0). Nonnal control group had lower scores than patients group in all 7 items(p=0.000). Correlation coefficients between K-ADL score and braindisability grade was between -0.465(eating) and -0.696(bathing)(p=0.000). CONCLUSIONS: Korean Activities of Daily Living(K-ADL) scale is a valid and reliable instrument. In the future, the studies showing an association between K-ADL and mortality, prognosis are needed.

Ki-1 lymphoma is a rare, large cell anaplastic non Hodgkin's lymphoma. It expresses the CD30 antigen and is recognized by the antibodies Ki-1. This Ki-1 positive anaplastic lymphoma was first described in 1985 as a new histological subtype and was added to the updated Kiel classification in 1988. Morphological and immunological features of this lymphoma have been well described, but clinical studies have been limited and follow up has been short. The authors report a case of Ki-1 lymphoma of the skin without systemic involvement in a young adult based on clinical, pathological and immunological features.

BACKGROUND: Korean Instrumental Activities of Daily Living(K-IADL) scale was developed to measure the elderly function. The aim of the present study was to establish the validity and reliability of K-IADL scale. METHODS: Clinical validity and convergent validity was tested. Reliability was tested by internal consistency(Cronbach`s alpha), two weeks test-retest method, and interrator correlation. RESULTS: Cronbach`s alpha was 0.938. 2 weeks test-retest correlations in all 10 items were higher than 0.674. Interrator agreements were high in all 10 items(H=0.808~0.947). Normal control group had lower scores than patients group in all 10 items(p=0.000). Correlation coefficient between K-IADL score and brain-disability grade was between -0.336(laundry) and -0.663(using transportation)(p=0.000). CONCLUSIONS: Korean Instrumental Activities of Daily Living(K-IADL) scale is a valid and reliable instrument. In the future, the studies showing an association between K-IADL and mortality, prognosis are needed.

8.Relationship of Calcitonin Gene-Related Peptide and Pediatric Headache in Obesity.
Journal of the Korean Child Neurology Society 2011;19(1):47-53
PURPOSE: Both headache and obesity are prevalent and chronic conditions among children. A well-known pathophysiology of migraine is that calcitonin gene-related peptide (CGRP) is an important postsynaptic mediator of trigemino-vascular inflammation. Plasma CGRP levels have been shown to increase in obese individuals during the headache phase of migraines. The purpose of this study was to assess the relationship between headache and plasma CGRP levels in obese children. METHODS: We prospectively studied plasma CGRP levels in 33 patients (20 overweight and obese subjects without headache, 13 overweight and obese subjects with headache) who visited Chosun University Hospital from March 2009 to September 2009. Blood samples were collected from cubital veins and plasma levels of CGRP were measured by radioimmunoassay. RESULTS: The mean age was 12.3+/-2.3 (range 6-15 years) and mean CGRP level was 19.1+/-2.5 pg/ml in the overweight and obese with headache group and 17.4+/-5.1 pg/mL in the overweight and obese without headache group. In the group CGRP levels lower than 19 pg/mL, mean headache frequency per month, mean severity, and mean disability were 17.0+/-18.4, 4.0+/-2.8 and 2.0+/-0.0, respectively. In the group with CGRP levels of 19 or greater pg/ml, levels were 11.0+/-9.8, 5.6+/-1.0, and 23.1+/-8.2, respectively. CONCLUSION: The mean CGRP level in overweight and obese children with headache was not significantly higher than in those without headache (P =0.202). Further, there was no significant correlation between CGRP level and frequency, severity of headache, and disability due to headache (P > 0.05). Further studies are needed to access the relationship of CGRP and pediatric headache in obese subjects.

Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.
