Forty-three patients with papulo-pustular rosacea with Demodex(D.) folliculorum were treated for 8 weeks on a random basis either with tetracycline 250 mg three times daily or with metronidazole 250 mg three times daily. Both drugs produced an improvement which was greater after 8 weeks than after 4 weeks, but there was no significant difference between them. The number of D. follilculorum after treatment with tetracycline was slightly decreased, but the number of D. folliculorum after treatment with metronidazole was more decreased than the tetracycline group. Metronidazole appears to be a effective drug for the treatment of rosacea with D. folliculorum.

Lichen planus is rare in Korea and localized lichen planus on the lip without other skin lesions is even rarer. A 77-year-old man has oozing and crusting patches und somewhat ulceration surrounded by whitish reticular elements on violaceous base on both lips with burning sensation and pain. A 63-year-old man has well demarcated violaceous white reticular patches on the lower lip, buccal mucosa, glans penis and coronal sulcus. Clinical and histopathological studies of two cases showed typical features of lichen planus. They were treated with systemic and topical corticosteroids and showed much improvement.

The important prerequisite for treatrnent of onychomycosis is the removal of as rnuch fungus-infected nail material as possible. Nincty-five patients with anychomycosis were treated with using urea preparations under occlusive dressings. The urea preparations were quite successful in maceraing the nail plate from the nail bed, allowing the easy removaI of diseased nails in all cases except one. The urea preparations removed only abnormal nail. Completely normal nail was unaffected. After nail avulsion, 95 patients were treated for 6 months with combination clotrimazole and ketoconazcile(group A), or with clotrimazole only(group B). Of the 38 patients in group A who complcted the treatment, 25(65.8%) were cured 6 months later by clinical and mycological criteria, compared to 20(47.6%) of 42 patieries in group B.

Spontaneous rupture of the quadriceps tendon has heen rarely reported. We experienced four knees of 3 patients. Two patients with chronic renal failure(CRF) had been treated with peritoneal dialysis and the other patient was healthy without significant medical problem. In the CRF patients, laboratory studies were coincided with secondary hyperparathyoidism. Radiologic and operative findings suggested that the repeated minor trauma caused avulsion fracture of the bone near the insertion site of the tendon. Histologic findings revealed no elastosis of the tendon and no deposit of amyloid in the quadriceps tendon. In the non-CRF case, there was normal lahoratory data, and the rupture occurred at the musculotendinous junction, suggesting sudden contracture of the muscle causing failure without trauma history. All cases were treated successfully with open repair of the quadriceps tendon. It could be summarized that the site of spontaneous rupture in the CRF and normal patient were different.

BACKGROUND: Since the exact pathogenesis of sepsis-induced ARDS has not been elucidated, the mechanisms of enhanced neutrophilic respiratory burst were probed in endotoxin primed neutrophils associated with the roles of phospholipase A2 (PLA2), platelet activating factor (PAF) and apoptosis. METHODS: In isolated fresh human neutrophils, effects of the inhibition of PLA2 and PAF on the apoptosis were examined by the method of Annexin-FITC/dual PI flow cytometry. The roles of PLA2 and PAF on the neutrophilic respiratory burst were also examined by measuring oxidant generation in cytochrome-c reduction assay. Activities of the PLA2 and lysoPAF acetyltransferase (lysoPAF AT) of the neutrophils were determined to understand the effect of endotoxin on these enzymatic activities which may be related to the neutrophilic respiratory burst and apoptosis. In addition, the role roles of PLA2 and PAF in neutrophilic adhesion to bovine endothelial cells were examined in vitro by neutrophil adhesion assay. To investigate the effect of oxidants on pulmonary surfactant, cytochemical ultrastructural microscopy was performed. To inhibit PLA2 and PAF, non-specific PLA2 inhibitor mepacrine (100 nM) and WEB 2086 (100 nM) or ketotifen fumarate (10 kg/ml) were used respectively in all in vitro experimental sets. WEB 2086 is PAF receptor antagonist, and ketotifen fumarate is a lyso PAF AT inhibitor. RESULTS: The mapacrine treatment, provided after the endotoxin (ETX) treatment, resulted in increased apoptosis of neutrophils (p<0.001) while treatments of WEB 2086 and ketotifen did not. The inhibition of PLA2 and PAF decreased (p<0.001) production of oxidants from PMA-stimulated neutrophils. While endotoxin increased the PLA2 activity of neutrophils (p<0.01), mepacrine supressed (p<0.001) the activity, provided after treatment of ETX. The lyso PAF actyltransferase activity (lyso PAF AT) increased(p<0.01) after treatment of ETX. In contrast, mepacrine, WEB 2086 and ketotifen showed a tendency of decreasing the activity after treatment of ETX. The Treatment of ETX increased (p<0.001) neutrophil adhesion to endothelial cells, which was reversed by inhibition of PLA2 and PAF (p<0.001). The binding of oxidants to pulmonary surfactant was identified histologically. CONCLUSIONS: The enhanced neutrophilic respiratory burst by ETX plays a pivotal role in the pathogenesis of ARDS in term of oxidayive oxidative stress. Increased production of oxidants form neutrophils is mediated by the activations of PLA2 and lyso PAF AT.

The purpose of this study was to know the effect of short termed fasting on the usage of metabolic energy sources and the metabolic differences between non-athletic and athletic subjects. Subjects were divided into non-athletic and athletic group and exercise was loaded on both groups after feeding and fasting. Exercise was loaded by a treadmill running at the speed of 8 km/hour for 30 minutes in both groups. The experiment yielded following results. In the fed state, the level of plasma FFA increased markedly after 15 and 30 minutes of exercise compared with it's level of pre-exercise period in both groups. In the fated state, the level of plasma FFA in non-athletic group increased steadily according to the duration of exercise, while it's level in athletic group showed no changes. At pre-exercise period, the level of plasma FFA was higher in fasted state than fed state. Immediately before the exercise and 15 and 30 minutes after the exercise, blood for the determination of plasma free fatty acid (FFA), glucose, triglyceride (TG) and cholesterol was sampled from antecubital vein, and simultaneously heart rate was measured. In the fed state, the level of plasma glucose was increased mildly according to exercise, and in the fasted state it's level increased according to exercise in both groups also. In the fasted state, the level of plasma TG was lower than that in the fed state. The level of plasma TG and cholesterol in the fed state was no changed by the exercise from the pre-exercise period. The level of plasma cholesterol in athletic group had tendency to lower than that in non-athletic group. Heart rate increased markedly according to exercise in both groups, but the athletic group's increasing rate of heart rate was lower than the non-athletic group's heart rate increased according to exercise and athletic groups heart rate increased early period of exercise, but did not change during latest post-period of exercise.
