In order to measure the MPD with 8-methoxypsoralen, we selected 49 Korean healthy male vlunteers without phototoxic or photosensitive dermatoses. They were divided to 3 groups (Immediate; group 1, 1 hour; group 2, 2 hours', group 3) according to the waiting time, intervals of application of photosensitizer a,nd UVA:irradiation. The reaults were summarized as follows: 1. MPDs of group 1 had no clinical significance. 2, MPDs of group 2 were more than those of group '3 independently of application methods of photosensitizer. 3. In the cases of topical application of 8-MOP, MPDs of group 3 according to reading interval (24 hours, 48 hours and 72 hours after UVA irradiation) were 3.4+/-2.9 J/cm2, 1.9+/-l.5 J/cm' and l. 7+1, 2/cm, respectively. 4 In the cases of oral administration of 8-MOP, MPDs of group 3 according to reading; interval as topical application of 8-MOP were 7.1+/-2.3 J/cm, 4.4+/-1.1 J/ cm2 and 4.2+/-l.2 J/cm2, respectively. 5 MPL)s accarding to the skin types as follows; (waiting time; 2 hours, read- ing interval; 48 hours) a. In the case of topical application of 8-MOP, MPDs of the skin type ]II, 1V and V were 0.9+/-0.5 J/cm2, 1.8+/-1.1 J/cm2 and 3.0+/-l.3 J/cm2 respectively. b. In the case of oral administration of 8-MOP, MPDs of skin type g, W and were 3.5+/-1.1 J/cm2, 4.7+/-1.3 J/cm2 and 6.9+/-l.8 J/cm2, respectively.

We described a giant chroioangioma of the placenta that caused premature rupture of membranes at 31 weeks of gestation in a 31-year-old primiparous woman and a subsequent neonatal death of the baby. The placental mass, weighing 820 gm and measuring 21.5x15x4.5 cm, was easily shelled out from a edematous 1280 gm-placenta. The mass had a thin fibrous capsule and a solid fibromatous appearance. The infant, weighed 2175 gm, appeared edematous oon the whole body and had Apgar scores of 4 and 5 at 1 and 5 minutes respectively. The baby expired 4 days after birth due to high output cardiac failure and respiratory failure. Postmortem examination revealed markedly dilatated umbilical vein, inferior vena cava and right atrium with patent froamen ovale, congestive hepatosplenomegaly, pulmonary hemorrhages, and meconium aspiration pneumonia. Microscopically, the mass revealed a variety of histologic patterns, reflecting entire spectrums of villous vasculogenesis from loose myxomatous connective tissue and undifferentiated hemangioblastic cell nests to well-developed capillaries with hematopoietic cells in the lumen.

ICAM-l(Intercellular adhesion molecule-1) is an important early marker of immune activation and response. ICAM-1 is expressed on varous cell types and observed in a variety of diseases, including patients with asthma, melanoma, prostatic cancer, ovarian and colon cancer. Some authors demonstrated the expression of ICAM-1 protein in high-grade intraepithelial squamous neoplasia of cervix by immunohistochemistry and suggested that the expression was related to human papillomavirus infection. The aim of this study was to determine the serum levels of soluble intercellular adhesion molecule-1(sICAM-1) in patients with squamous cell carcinoma of the cervix, Serum levels of sICAM-1 were measured by enzyme-linked immunosorbent assay(ELISA), We evaluate invasive squamous cell carcinoma of the cervix (40), carcinoma in situ (16) and control (15) patients. Serum levels of sICAM-1 in healthy volunteers, in parients with carcinoma in situ and invasive cervical cancer were 150.1+/-41.3, 182.7+/-105.9, 189.8+/-60.0 ng/ml, respectively. Although the serum levels of sICAM-1 in patients with carcinoma in situ did not increase, serum levels of ICAM-1 in patients with invasive cervical cancer were significantly increased (control vs invasive cervical cancer, p < 0,05). From the above results, sICAM-1 is shed from the cancerous tissue in patients with squamous cell carcinoma of the cervix.

A lg year-old female patient with pityriasis lichenoides et varioliforrnis acuta (PLEVA) was been treated with PUVA, At first, she was treated with tetracycline for 8 weeks with improvement somewhat. But 2 months later, her skin lesions aggravated slowly. So, we tried to treated her with PUVA and then she was cleared completely. The initial dose of UVA was 5 J/cm The UVA dosage increased by 10g of the previous exposure and increased to the maximum dose, 15 J/cm The patient exposed to UVA R times per week. 12 times after the PUVA therapy, the skin lesions begin to improve and completely improved at 21 times of Pl.JVA therapy. She was followed up every week and there was no side effect except hyperpigrnentation till 24 months. The total dose during treatment is 210 J/cm.

Ischemia and reperfusion of skeletal muscle occurs in acute vascular occlusion and revascularization, in elective vascular surgery, in upper and lower extremity surgery by means of a tourniquet, and in free transplantation of muscle containing cutaneous flaps. During revascularization of skeletal muscle after ischemia, lipid mediators, mainly eicosanoids are released that may have a role in the pathogenesis of reperfusion injury. The exact role of eicosanoids in the imposed ischemia-reperfusion induced functional deficits in skeletal muscle is still unknown, we compared tissue edema and the changes of eicosanoids and the effects of cyclooxygenase inhibitor indomethacin in the rat right hindlimb by application of tourniquet ischemia-reperfusionn injury. After 4-hours of ischemia, reperfusion was established 4 hours by releasing tourniquet. Experimental groups comparised ischemia-reperfused animals pretreated with indomethacin 20 mg/kg. The control animals received normal saline, 4 hours of ischemia without reperfusion. To assess tissue edema, wet/dry weight ratios were determined and the concentrations of prostaglandins and thromboxane were measured by the high performance liquid chromatography with UV detector at 195 nm. Ischemia itself did not result in muscle edema and did not increase the release of cyclooxygenase metabolites, but muscle edema(52%, p<0.01), and the relase of 6-keto-PGFalpha(151%, p<0.01), thromboxane B2(98%, p<0.05), and PGE2(127%, p<0.01) were significantly increased by reperfusion. Indomethacin treatment ameliorated limb edema(35%, p<0.05 versus ischemis-reperfusion control) and decreased 6-keto-PGF1alpha(65%, p<0.05) releases. These results support view that cyclooxygenase products may play significant roles in the formation of ischemic muscle edema and suggest that nonsteroidal antiinflammatory agents and eicosanoids antagonists might be beneficial to the management of acute limb ischemia-reperfusion injury.

From Mar. 1984 to Mar. 1994, we carried out 18 revision operations in patients who received Girdlestone operation due to the infection of hip was 7 cases, tuberculosis of hip was 3 cases, deep infections after implant insertion of hip were 5 cases, and pyogenic sequela was 1 case. The mean conversion period was 27 months. The leg length discrepancy, range of motion of hip, and Trendelenberg gait were examined before and after conversion to a total hip arthroplasty. The last functional state was evaluated and radiological examination was performed. In summary and Conclusion; 1. The time of performing revision hip arthroplasty was assessed by clinical, radiologic and laboratory finding, and the average time of conversion to total hip arthroplasty was 7.6 months after Girdlestone operation. 2. There was no case of recurrence of infection after revision operations. 3. At last follow-up after revision hip arthroplasty, the mean Harris Hip Score was 87.2(69.6–92.2) point. 4. Six patients had no pain, 8 patients had mild pain, and 2 patients had moderate pain. Nine patients were able to walk without ambulatory aids and 7 patients needed crutch or cane for walking. 5. At the time of revision hip arthroplasty, the average shortening of the resected limb was 4.2cm(1.6–7.3cm), and after revision operation, the average shortening was reduced to 1.2cm(0.8–2.2cm) 6. The technical difficulties, such as increased bleeding, bone deficiency, scar tissue formation, and limb shortening were encountered in all cases. 7. The peroneal nerve injury was developed in one patient who had conversion hip arthroplasty at 13 months after Girdlestone operation.

Malignant fibrous histiocytoma, which is interesting because of its pleomorphic nature, is a rare soft tissue sarcoma possibly arising from histiocyte. The tumors are usually situated in the skin or subcutaneous tissues, especially of the extremities, but they may also involve deeper structures, such as the retroperitoneum or genital organs. Herin we report a case of malignant fibrous histiocytoma in the retroperitoneal space and discuss the pathologic and clinical features.

Progressive zosteriform macular pigmented lesion(PZMPL) is a chronic pigmentary dermatosis similar to progressive cribriform and zosteriform hyperpigmentation(PCZH). This dermatosis described by Simoes in 1980 is characterized by a uniformly tanned macular pigmented lesion in a zosteriform distribution preceded by multiple pruritic macular pigmentation in a part of the dermatome for a period. PZMPL is not a fully understood disease entity but it is thought to be a variant of PCZH. It is differentiated from PCZH by accompanying pruritus as a prodromal symptom, a characteristic clinical course, and histological findings such as pigmentary incontinence. We report herein a case of PZMPL in a 17 year-old girl with the pigmentary skin lesion extending from the left forearm to the left chest along the Blaschkos line. The histological findings revealed increased melanin pigments in the basal layer and focal pigmentary incontinence in the upper dermis. To our knowledge, this case is the first report of PZMPL in korea thought to be the same case reported by Simoes.

This study intended to obtain an useful information on the prevalence of subjective symptoms, and to clarify the interrelationships between blood lead and lead related symptoms in low level lead exposure. The 93 male workers exposed to lead and 56 male nonexposed workers were examined for their blood lead (PBB), Zinc-protoporphy (ZPP), hemoglobin (HB) and personal history, and completed 15 questionnaires related to symptoms of lead absorption; also measured lead concentration in air (PBA) in the workplace. The results obtained were as follow; 1. The means of blood lead (PBB), blood ZPP and hemoglobin (HB) among workers exposed to lead were 26.1+/-8.8 microgram/dl, 28.3+/-26.0 microgram/dl and 16.2+/-1.2g/dl; whereas those of nonexposed workers were 18.7+/-5.1 microgram/dl, 20.6+/-8.7 microgram/dl and 17.3+/-1.1g/dl. The means of above three indicies between two groups showed significant difference statistically (p<0.05). 2. The means of blood lead (PBB), blood ZPP and hemoglobin of workers exposed to different lead concentration in air were as follows; When it was below 25 microgram/m3 , the indices were 24.7+/-79, 26.1+/-26.8 microgram/dl and 16.4+/-1.1 g/dl respectively; These indices were 27.1+/-8.5, 23.9+/-10.92 /dl and 16.2+/-1.3 g/dl when the lead concentration in air was 25~50 microgram/m3; and they were 3.4+/-9.3, 42.3+/-31.3 microgram/dl and 15.5+/-1.2 g/dl when the concentration of lead was above 50 microgram/m3. Although there were statistical difference in blood lead and hemoglobin among three different lead concentration in air, there was no statistical difference of blood ZPP among the three groups with different exposure levels (p>0.05). 3. The most frequently by complained symptom was "Generalized weakness and fatigue", and fewest symptom was "Intermittent pains in abdomen". 4. Only two symptoms out of fifteen symptoms checked by themselves revealed significant difference between exposed and nonexposed groups. These were "Intermittent pains of abdomen" and "Joint pain or arthralgia" (p<0.05). No positive correlation was found between the levels of blood lead and symptom groups categorized as gastrointestinal, neuromuscular and constitutional symptoms. 5. Blood lead (r=0.3995) and ZPP (r=0.2837) showed statistically significant correlation with mean lead concentration in air, whereas correlations were not demonstrated between blood lead and lead related symptoms or blood ZPP and lead related symptoms. 6. Blood lead (PBB) and ZPP showed association (r=0.2466) and the equation PBB=23.75+0.0842 ZPP was derived. 7. On stepwise multiple regression, using blood lead level as a dependent variable and ZPP, hemoglobin (HB), age, work duration (WD) and symptom prevalence as a independent variables, only ZPP significantly contributed a lot to blood lead level. 8. While the ZPP measurement was found to be a good indicator in evaluating health effect of lead absorption in low level lead exposure, lead related symptoms were not sensitive enough to evaluate of lead absorption in low level exposure.
