Partial lipodystrophy(PLD) is a rare disorder characterized by frequent occurrence in women, usually onset in childhood, and slowly progressive symmetrical loss of subcutaneous fat on the upper half of the body. The etiology is unknown. However, many immunologic abnormalities were reported in PLD. Herein, we report a case of PLD in a 34-year-old man with familial occurrence of PLD in his brother.

BACKGROUND: Resistance to cytotoxic drugs such as cisplatin is an important cause of treatment failure in lung cancer. The mechanisms are omplex and have yet to be clearly elucidated, but the acquisition of drug resistance possibly has resulted in poor survival. The purpose of the study is to evaluate whether the resistant tumor cells would gain more potential for metastasis. MATERIAL AND METHOD: we examined the metastatic potential of a cisplatin-reisistant cell line, H460/CIS, which was established from the human lung cancer cell line H460 by in vitro selection with gradually increased concentration of cisplatin. The parental cisplatin-sensitive cell line(H460) was used as the control and analysis on the expression of angiogenesis or growth-related factors, gelatin zymographic analysis and in vivo spontaneous metastatic experiment in nude mice were done. RESULT: Increased levels of vascular endothelial growth factor(VEGF) and basic fibroblast growth factor (bFGF) were found in H460/CIS. Gelatin zymographic analyses showed that proteinase A in the culture medium of H460/CIS was processed from latent to activated form. The in vivo experiment showed that H460/CIS cells spontaneously metastasized to the lungs but parental cells did not. CONCLUSION: resistance to the chemotherapeutic agents may render the tumor aggressi-veness and metastatic potential. Therefore, the risk, rather than benefit, from inadvertent application of adj uvant or neoadj uvant chemotherapy to early-staged lung cancer should be considered.

Mesenteric panniculitis is an extremely rare inflammatory condition of the adipose tissue of unknown etiology. It is characterized by extensive, progressive fibrosis of the mesenteric fat tissue, leading to tumor formation. Clinical manifestations vary according to the process involving the structures. Abdominal pain accompanied by nausea, malaise, pyrexia, and weight loss and a poorly defined mass are common presentations. Major pathologic changes include (1) degeneration of mesenteric fat, (2) an inflammatory reaction, and (3) fibrosis of the adipose tissue. We present four patients with an aggressive form of mesenteric pannicultis with characteristic histopathologic features. We discuss the relationship between the histopathologic features and the surgical intervention in these cases.

OBJECTIVE: The purpose of this study was to evaluate the survival rate of vitrified blastocyst according to the freezing vessels, equilibration time in cryoprotectant and artificial dehydration method. METHODS: Human blastocysts were vitrified after loading onto the plastic straw, open-pulled straw (OPS), electron microscopy grid (EM grid) for 1.5 min or 3 min. They also were directly plunged into LN2 within 30sec. For artificial shrinkage of blastocysts, 36 gauge fine needle was pushed at the cellular junction of the trophectoderm into the blstocoele cavity until it shrank without damage of inner cell mass. RESULTS: The survival rate of vitrified blastocysts on plastic straw, OPS, EM grid as freezing vessels were 26.7, 13.0 and 60.5%, respectively. The survival rate of EM grid was significantly higher than that of plastic straw and OPS (p<0.05). For 1.5 min equilibrium, the survival rates of early blastocyst (EB), middle blastocyst (MB) and late blastocyst (LB) were 64.4, 81.0, and 20.0% respectively. For 3 min equilibrium, the survival rates of EB, MB, and LB were 69.9, 50.0 and 57.5% respectively. The survival rates of EB and MB were significantly higher than that of LB in 1.5 min equilibrium group (p<0.05), however, the significance was not observed in 3 min equilibrium groups. In cytoplasmic shrinkage before vitrification, the survival rates of EB, MB and LB were 92.9, 100 and 75.9% respectively. The survival rate of MB was significantly higher than that of LB (p<0.05). The survival rates of vitrified blastocysts by artificial dehydration and slow-frozen blastocysts were not significantly different as 88.9 and 66.7%, respectively. CONCLUSION: This study showed that the vitrification of human blastocysts using EM grid and artificial dehydration is an effective method. Therefore, these methods would be an useful techniques for blastocyst cryopreservation.

OBJECT: This study was carried out to evaluate immunologic difference between baseline and after 4 weeks drug treatment with atypical antipsychotics (rispreidone) by measurement of serum concentration of 6 cytokines. METHODS: The subjets were composed of 25 patients who are admitted at Dajeon St's Marys hospital of psychiatry department and diagnosed as schizophrenia by DSM-IV diagnositc criteria. We measured serum IL-1beta, IL-2, IL-6, IL-12, INF-gamma, TNF-alpha concenatrations by quantitative ELISA method using ELISA kit (Endogen Inc., Woburn, MA, USA).The two psyciatrists performed PANSS examination between baseline and after 4 weeks risperidone treatments. RESULTS: The serum level of IL-12 was increased significantly after medication of 4 weeks and the serum concentration of IFN-gamma showed the tendency of decreasement but not significant. The serum level of the other cytokines showed no significant change. CONCLUSIONS: We spectulate that the increasement of IL-12 may contribute to role of activation of immune response by treatment of antipsychotic medication (risperidone). This study is first trial of IL-12 study in neuropsychiatric field and IL-12 which play important role of immune response becomes interesting subjects in immune research.

Vitiligo and morphea are two distinct entities of unknown etiology, although their existence implies that the immune system and/or the central or peripheral nervous system has been incriminated. Only a few reports of their simultaneous occurrence are on record. Here we report a case of a 39 year old woman affected with both vitiligo of the face, chest and hand and morphea of shoulder and trunk. Since the two diseases appeared after bone marrow transplantation, if could be deduced that there is a possible association between them. Two diseases observed simultaneously in this patient may be derived from the common pathomechanism. An autoimmune etiology is thought to play a part in both of these diseases.

Chrome may have a corrosive, necrotizing effect on tissue, so repeated skin contact to chromate might induce perforations or ulcers on the skin. This condition is called a "chrome ulcer" or "chrome hole". It appears as a small, punched-out mark with a rolled-out border. It is rarely associated with pain, but a severe itching sensation is common. We report a case of a 33-year-old man who presented with a 3 month history of several ulcers on his abdomen. He was employed at a chromate alloying process. He had several hole-like atrophic scars and unbearable pruritus. After changing his occupation, plus treatment with oral corticosteroids and antihistamines, the lesions were healed and the itching sensation faded away. However, atrophic scarring remained.
