It is generally recognized that several chemical mediators are involved in tbe pathogenesis of sunbum; however, the exact mechanism is still to he resolved. Recently, prostaglandin has been found to be one of the inflammatory mediators in sunbum, particularly in the delayed erythema response and several investigators have shown that the nonsteroidal antiinflammatory drugs inhibit the in vivo synthesis of prostaglandin. On the assumption that the nonsteroidal antiinflammatory drugs might exert a beneficial effect on the sunbum through the antiprostaglandin effect, several authors have reported the effect of indomethacin on sunbum. This study was undertaken to evaluate the effect of topical indomethacin on the delayed erythema response induced by artificial sunlamp and sunlight by clinical and histopathological examination. Indomethacin(2. 5% ointment, 2. 5% solution, 5% solution) was applied immediately after 3 MED irradiation of artificial sunlamp to the shaved back skin of 6 healthy albino guinea pigs weighing 550-850gm and 9 human volunteers and the delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours after irradiation respectively. Punch biopsies of the skin were performed on 6 guinea pigs at 6, 12, 24 a.nd 48 hours after irradiation and the histologic changes were observed. Four human volunters were exposed t,o 3 MED of sunlight and indomethacin preparations were applied immediately after irradiation. The delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours postirradiation and in one volunteer, the skin was biopsied at 24 hour for histologi.c evaluation. The results were as follows: 1. Topical indomethacin in ointment or solution forms delayed and decreased the appearance and degree of erythema induced by sunlight and artificial sunlamp in both human and animal subjects. 2. Histologically, the number of sunbum cells at 24 hour in the epidermis of one human volunteer was decreased on indomethacin applied sites. The dermis showe6 no difference in histologic changes between control and indomethacin sitea. In animal study, however, no detectable difference in epidermal or dermal changes was observed between control and indomethacin applied sites. The autors confirmed that topical indometha,cin was effective in delaying and blanching of the delayed erythema of sunbum in guinea pigs as well as in human volunteers, though there was no difference in histologic changes between indomethacin and control sites in guinea pigs. The mechanism involvel on this aspect is remained to be resolved.

BACKGROUND AND OBJECTIVES: Studies in patients with mitral valve prolapse syndrome (MVPS) have shown the coexistence of various forms of autonomic dysfunction, and so this is an area that requires further investigation. METHODS AND MATERIALS: The study group consisted of 65 patients (36 men and 29 women), aged 16 to 43 years (mean+/-SD, 28+/-8) with symptomatic, echocardiographically proven mitral valve prolapse (MVPS) who were free of other organic heart diseases and arrhythmias. In a prospective study, heart rate variability (HRV) indexes were calculated from 24-hour Holter recordings obtained during normal daily activity and plasma norepinephine was measured, and then these data were compared among the study group according to clinic heart rate (HR). RESULTS: The study group was divided into below 60 bpm (group 1: n=13), 60 - 80 bpm (group 2: n=36) and over 80 bpm (group 3: n=16) on the basis of clinic HR. These patient groups were matched with respect to age and gender. There were significant difference in SDNNIDX, rMSSD and pNN50 between these groups (p=0.005, 0.009 and 0.002 respectively), and these HRV measures correlated inversely with clinic HR (p<0.01). As clinic HR increased, there was a tendency for plasma norepinephrine concentration to also rise (p<0.05), but there was no statistical significant difference between these groups. CONCLUSION: Our data suggests that MVPS may have subgroups of HRV, reflecting cardiac autonomic modulation, according to clinic HR.

Ovarian tumor in pregnancy is not rare and benign cystic teratoma is most common ovarian tumor in pregnancy. Most ovarian tumor in pregnancy is found at first and second trimester but sometimes found at third trimester and it is difficult to make a decision for management. Moreover physician should consider fetal age and mother's condition, and weigh outcome of operation for complicated ovarian tumor in pregnancy. Torsion of ovarian tumor is not an uncommon complication during first trimester of pregnancy and puerperium but rare occurs during the third trimester of pregnancy. We have experienced a case of torsion of benign cystic teratoma of ovary which occurred at 37 weeks gestation in a 25 year-old woman. So we report this case with a brief review of literature.

Osteoblastoma is a rare tumor which forms osteoid and bone with highly vascular stroma, account for less than 1 percent of all bone tumors. The lesion had been thought to be controlled with curettage and locat excision. In recent years, cases of locally aggressive but not metastasizing osteoblastomas have been described as aggressive osteoblastoma or malignant osteoblastoma, separated from the innocuous behavior of usual osteoblastoma. It represents the histologic characteristics of the presence of epithelioid osteoblasts, trabecular rather than lace-like osteoid, low mitotic rate with no atypical form with prominent giant cells of osteoclastic type The differential diagnosis between aggressive osteoblastoma and osteogenic sarcoma is extremely difficult, but its peculiar histologic pattern and ist different clinical and radiologic features and better prognosis are helpful. We report here a case of aggressive osteoblastoma of 17 years old female patient with 2 years and 5 months follow-up period and review the literature.

OBJECTIVES: To evaluate the urinary concentrations of hydroxyridinium crosslinks of collagen in patients with osteoarthritis(OA) or rheumatoid arthritis(RA), and to compare its clinical correlation with the classic indices of the disease activity of RA. METHODS: Concentrations of urinary pyridinoline (Pyd) and deoxypyridinoline(Dpd) were measured in urinary samples collected from 18 control patients, 35 patients with OA, 45 patients with RA by competitive enzyme immunoassay using microplate coated with monoclonal antibody. RESULTS: 1) Mean urinary concentrations of Pyd in OA patients were 33.5nmol/mmol creatinine, in RA patients were 50.0nmol/mmol creatinine which were higher than the values in controls (25.1 nmol/mmol creatinine). Also, mean concentrations of Dpd in OA patients were 9.2nmol/mmol creatinine, in RA patients were 10.1nmol/mmol creatinine which were higher than the values in controls(5.6nmol/mmol creatinine)(p<0.01). 2) Mean urinary concentration of Pyd was 50.0 nmol/mmol creatinine in RA patients, which was significantly higher than the values in OA(33.5 nnmol/mmol creatinine)(p<0.05), but the mean Dpd concentratians were not significantly different between the two groups. 3) The concentrations of urinary Pyd in RA patients was significantly correlated with the biologic markers indicating inflammatory activity such as ESR(r=0.68, p<0.001), CRP(r=0.72, p<0.001) and the number of tender joint(r=0.66, p<0.01) CONCLUSION: Urinary concentrations of Pyd and Dpd were significantly higher in OA and RA patients than in controls, Especially urinary Pyd concentrations were significantly increased in RA patients than in OA patients, and strongly correlated with disease activity index of rheumatoid arthritis. The mean Dpd concentration, bone specific analogue, in RA patients was not significantly different from that of OA patients and it was not correlated with disease activity index Thus measurement of urinary Pyd might provide a sensitive, noninvasive biochemical marker for studying activity of RA.

Benzoyl peroxide has been known to have bacteriostatic activity against Corynebacterium acnes and to have comedolytic action in patients with acne vulgaris. The present study was undertaken to evaluate the therapeutic effect of Renoxal, a 5% benzoyl peroxide lotion, in patients with acne vulgaris. A total of 35 patients entered this study at the Department of Dermatology, Seoul National University Hospital during the five months period from March to July, 1978. All patients were instructed to apply Benoxal on their affected sites once or twice daily; and the number of lesions on three fixed areas were counted before and every week for four weeks after the treatrnent. Two female patients stopped the application due to developrnent of contact dermatitis to Benoxal The results observed in the 33 patients were as follows: 1. The percentage decrease in total number of lesions in four weeks after treatment was 51.1% 2. Closed and open comedones were gradually eliminated; and their numbers were decreased in four weeks after treatment by 45. 8% and 55. 3% respectively. The papules were decreased. by 59. 1 @2 after the first week of treatment, but showed. a transient lag around tbe second week and then marked 61. 5% in four weeks after treatment. 3. Observed side effects included burning sensation,(3 cases), tightness (3 cases), itching sensation (2 cases) and scaling (1 case). All were tolerable without any specific measure or discontinuance of the application. The authors concluded througb this experiment that Benoxal (5% benzoyl peroxide lotion) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

BACKGROUND: During normal wound healing the formation of scars and fibrous tissue occurs, which consists largely of collagen fibril, but excessive fibrosis and scar formation become clinical problems. Collagen remodelling during scar formation is dependent on both continued collagen synthesis and collagen catabolism. Halofuginone, a plant alkaloid, is known to inhibit collagen type I synthesis at the transcriptional level. OBJECTIVE: The purposes of this study were to investigate the effects of topical application of halofuginone on the healing of wounds. METHOD: Topical solutions containing halofuginone of variable concentrations were applied on the full-thickness excisional wounds of hairless mice and 0.1% halofuginone ointments applied on the suture site of rats and the normal skin of hairless mice daily. In addition, we performed a one-time intradermal injection of 0.1% halofuginone solution on the normal skin of the hairless mice. We examined the collagen content of the skin of hairless mice and rats treated with halofuginone solutions and ointments during the healing process by performing hematoxylin-eosin and Masson's trichrome stains. We assessed, from time to time, the change in the full-thickness excisional wound size of hairless mice treated with halofuginone solutions of variable concentrations during the healing process and observed clinically the healing process of hairless mice with the full-thickness excisional wound. RESULT: 1. The wound size after daily application of 0.001% and 0.1% halofuginone solutions on the full-thickness excisional wounds of hairless mice decreased more slowly in comparison with the control group (p < 0.05).

Cloeortolone (9-a-chloro-6-a fluoro-11-B 21 digydroxy-16 methyl preganl,4-diene) is a newly synthesized corticonsteroid which has been found to have potent antinflammatory action and good tolerance through animal experiment. Several investigators reported its therapeutic affect in various dermatoses by topical application. The present was undertaken to evaluate the therapeutic effect of 0.1% clocortolone cream (Purantix-Sandoz) in patients with eczematous dermatoses and with psoriasis and to compare its effect with that of I% hydrocortisone. Eleven patients with contact dermatitis, 10 with psoriasis entered this study durtin the period of 6 months from January to june, 1977 at the Department of Dermatology, Seoul National University Hospital. All patients were instructed to apply 0.1% Clocortolone cream on one side of their lesion and 1%hydrocortisone cream on the opposite site for two weeks. After wo weeks' period of observation the status of the lesion was evaluated clinically and the tesults were as follows. 1. Ninety one percent of patiens with contact dermatitis, 70% of atopic dermatitis, 60% of nenrodermatitis, 67% of nummular eczema and 60% of psoriasis responded very effectively or moderately effectively. The therapeutic responses were generally similar to that of 1% hydrocortisone. 2. During the ovservation period, there was no systemic of local side effect of 0.1% Clocortolone cream.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.
