To know the effect of subconjunctival injection of liposome encapsulated cytarabine on proliferation of conjunctival fibroblasts, the conjunctiva was isolated at 180 degrees from the injection site 3 days after subconjunctival injection of the normal saline (control), cytarabine, liposome encapsulated cytarabine, and 1 day after injection of cytarabine, and then those were inoculated in the culture media of fibroblasts. In the case of 3 days after injection of cytarabine, there was 49% and 42% inhibition of proliferation of conjunctival fibroblasts compared with the control respectively. Therefore, the authors concluded that the liposome encapsulated cytarabine is effective on inhibition of proliferation of conjunctival fibroblasts and reduces the frequencies of subconjunctival injection compared with the cytarabine itself.

BACKGROUND: Superoxide dismutase(SOD) is an essential enzyme of protective defense mechanism in cellular compartments against the potential cytotoxicity of superoxide anion. It seems SOD activity is increased in psoriasis because of an increase in oxygen intermediates due to hyperoxia. However SOD activity is decreased paradoxically. OBJECTIVE: In order to understand the pathophysiology of psoriasis and to elucidate the significance of SOD activity in keratinocyte proliferation, we measured the SOD activities in psoriatic and in normal skin. METHODS: Authors assayed the level of SOD activities in 16 psoriatic and 16 and skin specimens, which were obtained from face/neck(1 and 4 specimens), forearm(5 and 4 specimens), trunk(6 and 3 specimens), and lower extremity( 4 and 5 specimens). We also investigated changes of SOD activity by age and regional differences of SOD activities in the psoriatic and normal skins. RESULT: First, activities of total SOD, Mn-SOD and Cu, Zn-SOD were 12.75+/-8.15, 4.28+/-3.62, 8.48+/-6.37 units/mg protein respectively in the psoriatic skin. Activities of total SOD, Mn-SOD and Cu, Zn-SoD were 17.63+/-9.10, 3.38+/-14.25+/-8.16 units/mg protein respectively in the normal skin. There as a significant difference between psoriatic and normal skins in Cu, Zn-SOD and Cu, Zn-SOD activities showed no significant differences between the age groups. Third, in sun exposed area and unexposed area, there were no significant differences between the psoriatic and normal skins in SOD activities. But it the normal skin, there were significant differences between sun exposed area and unexposed area in total SOD and Cu, Zn-SOD activities. CONCLUSION: There is a significant difference between psoriatic and normal skins in Cu, Zn-SOD activity. Namely, the Cu, Zn-SOD activity is significantly decreased in psoriasis.

Hypereosinophilic syndrome represents a heterogenous group filisorders with the common features of idiopathic prolonged eosinophilia of undetectable cause and orgar, system dysfunction. We experienced a case af hypereosinophilic syndrome in a 58 year old man who has been suffered from fever, chilling, generelized exfoliative dermatitis, periorbital sngioedema and oral ulcer for 3 weeks duration. The blood eosinophil count was 7436/mm and skin, liver, bone marrow biopsy revealed marked infiltration of eosinophils. We treated him with co ticosteroid, but 5 months later, he died due to hepatoencephalopathy, hepatorenal syndrome, dissernimted intravascular coagulopathy and acute respiratory distress syndrome.

We are reporting a case of molluscum contagiosum in a 3-year-old boy who showed a good response to diphenylcyclopropenone (DPCP) immunotherapy. The lesions were multiple, 2 to 7mm in size, centrally umbilicated, normal skin-colored papules of 7 months' duration which were distributed on the penoscrotal area, extremities and trunk. In spite of several treatments using extraction and curettage, new lesions developed continuously. The patient was sensitized with 0.1ml of 1% DPCP solution in acetone on his right shoulder and there-after challenged with solution of varying concentrations (0.05 to 0.1%) on his left shoulder once or twice a week to maintain a mild eczema. Clinical improvement was noted 1 week after sensitization and almost all of the lesions cleared after 8 week's treatment.

BACKGROUND: This study examined hemodynamic variables, oxygen delivery, extraction, and consumption in response to acute progressive hypoxia and hypercarbia in the setting of apnea. METHODS: Apnea was induced in 9 healthy mongrel dogs by disconnecting animals from mechanical ventilation of 30 minutes with pure oxygen. Hemodynamic variables, oxygen transport, extraction, and consumption were rapidly and repeatedly measured using pulmonary arterial and arterial catheters until cardiac output was undetectable. RESULTS: The baseline PaO2, PaCO2, pH, base excess were 318 +/- 137 mm Hg, 36 +/- 3.5 mm Hg, 7.30 +/- 0.06, 6.81 +/- 2.65 mmol/l respectively. Hypercarbia and hypoxemia (76 +/- 33 mm Hg) was first noted at 1 and 4 minute respectively. Base excess was not changed. Indices of preload (PCWP and CVP) were increased early in the time course (p<0.05). In contrast, indices of afterload (SVR) increased later, just before cardiac decompensation began (p<0.05). No significant reduction of cardiac output, oxygen delivery, extraction, and consumption was detected just until abrupt cardiac decompensation started, 5 minute. CONCLUSIONS: These data suggest that the early increase in preload was primarily due to hypercarbia whereas the late increase in afterload was due to hypoxemia, but the main cause of acute cardiac decompensation was a critical decrease in arterial oxygen tension with some contribution of increased preload and afterload.

Hyperkeratosis of the nipple and areola is a rare condition. We report a case of hyperkeratosis of the nipple and areola occurrinp in man with no underlying endocrirop thy or synthetic estrogenic drug therapy. The patient was not associated with epidermal nevus orichthyosis and so fitted into the nevoid form of hyperkeratosis of the nipple and areola. The clinical appearance and histological findings of the lesion were the same as those reported before. He showed a slight improvement in the color and hyperkeratcsis of the nipple and areola with 6 months use of a topical keratolytic agent and corticosteroid crearn.

Dentocutaneous fistula of the face neck is an infrequent manifestation of chronic dental infection. A periapical dental abscess may be initiated by disease, trauma, or thermal or chemical injury and develops into an extensive necrosis of surrounding tissue. Diagnostic errors can result in multiple excision, biopsies, and ineffective long-term antibiotic therapy. Awarness that periapical dental abscess is the most common etilolgic factor of cutaneous sinus tracts involves the face & neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. From 1994 to 1998, we have performed 6 cases of dentocutaneous fistula. Among of them, three were men and the others were women, age ranged from 18 to 66-year-old, and morbidity period was from 3 weeks to 3 years, the follow-up period ranged from 5 to 18 months (mean period 11 months). In conclusion, an understanding of the pathogenesis of cutaneous fistulae arising from dental infections will lead to proper early diagnosis and treatment without unnecessary surgery.

The double-blind, placebo-controlled study was performed to evaluate the efficacy and safety of once-a-day terazosin in 35 patients with benign prostatic hyperplasia. The dose of terazosin was titrated to 5 mg during 4 week period and then maintained throughout 24 week follow up. In terazosin group(n= 18), the maximum flow rates improved 32% from 10.4ml/sec at baseline to 13.7ml/sec, and the mean flow rate improved 38% from 5.5ml/sec to. 7.6ml/sec after 24 weeks of treatment(p <0.01). The obstructive symptom score decreased 59% from 9.8 to 4.l, and the irritative symptom score decreased 34% from 5.4 to 3.5 after.24 weeks of terazosin therapy (p<0.01). In placebo group(n= 17), the obstructive symptom score only significantly decreased 39% from 9.1 at baseline to 5.5 after 24 weeks of terazosin therapy(p>0.06). Adverse event occurred in one case of the terazosin group. In summary, terazosin administered once-a-day improved the obstructive and irritative symptoms of BPH and urine flow rates. Terazosin was well tolerated.
