In order to evaluate the the effectiveness of low-dose longterm Vibramycin (Doxycycline) treatment on Acne Vulgaris, a double-blind study was performed on fifty two patients with Acne Vulgaris. The patients were classified as to the severi.ty of their disease before treatment according to Wand. et al. The degree of the effcctiveness of the treatment was evaluated every other week for 12 weeks on the grounds of clinical improvement. The therapeutic results obtaincd were as follovs: araong the 19 patients who received 50 mg per day for 12 weeks, 13 cases (72.2%) showed excellent improverrent after 6 weeks; whereas in thc placebo group only 4 out of 15 patients (26. 7%) showed good response, Statistical analysis of the data revealed that there was a significant difference (p<0.05) in effectiveness between the Vibrarzycin 50mg per day group and the placebo group. Among the 19 patient who received a 100mg capsile orally per day for 4 weeks (subsequently this group received 50mg per day for 8 weeks) 13 cases.(68.4%) showed excellent improvement in 4 weeks; whereas in the placebo group only 4 cases(26, 7%) showed good respnnse Statistical analysis of this data revealed that there was a significant difference (p<0. 05) in efectivencess the Vibramycin 100mg per day group and the placebo group, It was noted that 44 out of 52 patients (83%) had a distinct family history of the disease, suggesting that there might be a predisposing hereditary factor involvcd in the manifestation of Acne Vulgaris It is concluded f rom this study that Vibramycin, when administrated in a dose of 50mg per day for more than 6 weeks is effective in the treatment of Acne Vulgaris.

Left ventricular hypertrophy is a compensatory response to hemodynamic overload secondary to an increased systemic resistance. This increase, however, is not the only cause of hypertrophy, and there are other factors which can have a significant effect on its incidence. To determine whether chronic antihypertensive therapy by enalapril modifies the cellular and subcellular changes of left ventricular hypertrophy observed in spontaneously hypertensive rats(SHR), 20-weeks-old SHR were treated for 22 weeks with enalapril(2mg/kg) and compared with normotensive Wister-Kyoto rats and not-treated SHR. Systolic blood pressure in enalapril-treated SHR was significantly lowered after 22 weeks compared with that of untreated control SHR group. Myocytes were reduced in size and fibrination seen in cardiac muscle fibers of control SHR was decreased in treated SHR group. Myofibrils appeared to be irregular in shape and myofilaments are decreased in control SHR but in enalapril-treated SHR the diameter and length of the myofilament became turned to regular forms. These results suggest that, enalapril, angiotensin converting enzyme inhibitor, may regress hypertrophy and some subcellular changes may be modified by enalapril.

We observed three patients who showed widespread macular ashy-colored eruptions. They fit clinically and histopathologically with the typical erythema dyschromicum perstans (ashy dermatosis). Erythoma dyschromicum perstans is a peculiar pigmented condition of unknown etiology characterized by persistent ashy-gray colored macule, refractory to any modality. All of them have similar skin lesions which are multiple, variable sized oval-shaped, ash-colored macular eruption on the trunk and extremities. Histologic findings of 2 patients reveal the characteristic feature of focal hydropic degeneration of the basal cell layer of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium, however, merely pigmentary incontinence into the corium in 1 patient. Literatures are briefly reviewed.

Higenamine is known to possess stimulatory activity on beta-receptor of the heart. Chronotropic actions of higenamic were studied in spontaneously beating right atrial muscle isolated from rabbits. The frequency of spontaneous beating and the relative threshold voltage of the right atrium were examined. The relative threshold voltage was defined as the minimal voltage of the given impulse above which the right atrium could be paced at the frequency of 20% of higenamine was also observed. Higenamine caused the postive chronotropic effect. This response became prominent as the ca2+ concentration in the bathing solution lowered. When tetrodotoxin was added to the bathing solution, the effect of higenemine altered and became similar to that of epinephrine. Higenamine reduced the relative threshold voltage of the right atrium in the bathing solution with [ca2+] of 0.5mM. Such effect was abolished by tetrodotoxin. The effects of verapamill on the spontaneous rate and the relativel threshold voltage were inhibited by higenemine. The above results suggest that, aithough the main action og higenamine is on the Ca channel, higenamine also have a minor effect of augmenting the Na channel.

Acropustulosis of infancy is an uncommon, but not rare syndrome established as a new disease entity by Kahn and Rywlin(1976), which is characterized by recurrent, intensely pruritic vesicopustules on the distal extremities. We'd like to report a case of acropustulosis of infancy. Our patient was 19 month old girl who had been suffering from her skin disease since the age of 12 months. Intensely pruritic, 1 to 2 mm vesicopustules erupted on the palms, soles and the ventral aspects of the fingers. There were no bacteria, fungus and parasites(Sarcoptes scabiei) on the pustular lesions. Histopathologically, biopsy specimen of the left sole revealed large, well circumscribed intraepidermal pustule which was filled wth polymorphonuclear leukocytes. We confirmed our case as typical case of acropustulosis of infancy by it's characteristic clinical features and histopathologic findings. Severity of the skin lesions seems closely related to the dosage of dapsone. The eruptions were unresponsive to topical steroid, antibiotics and antihistaminics. But we observed that dapsone has dose dependent relationship with acropustulosis of infancy.

BACKGROUND: In spite of relative high risk of extrapyramidal side effect and tardive dyskinesia, it is common clinical practice to use antipyschotics in treatment of bipolar I disorder. But in Korea, there has been few study about clinical factors related with antipsychotics treatment in bipolar disorder patients. So the author studied about the clinical factors related with antipsychotics treatment in bipolar inpatients focusing on the comparison of risperidone and classical antipsychotics. METHOD: By reviewing medical record retrospectively, datas about patient-related, illness-related, and treatment-related clinical factors on antipsychotics use were collected. Association between antipsychotics dose and duration and clinical factors were analysed by statistical method. RESULTS: Aggressive behavior was only statistically significant factor associated with antipsychotics use. And in the case of aggression, maintenance dose of risperidone was not changed(p=0.84), but dose of classical antipsychotics was increased significantly(p=0.005). Total hospital days and antipsychotics treatment duration showed no difference between risperidone and classical antipsychotics treatment groups. CONCLUSION: Clinical factors associated with antipsychotics use was aggressive behavior. In the case of aggression, risperidone required lesser dose increment compared with classical antipsychotics.

BACKGROUND/AIMS: Ultrasonography is the easiest, fastest procedure for the diagnosis of choledocholithiasis, but the diagnostic failure are mostly because of the intrapancreatic level of this condition and the absence of bile duct dillatation. Endoscopic ultrasonography is a promising procedure for the diagnosis of extrahepatic cholestasis due to noninvasiveness and accuracy in the digestive gas interposition. The aim of this study was to prospectively compare the diagnostic accuracy of endoscopie ultrasonography with abdominal ultrasonography and endoscopic retrograde cholangiography in 66 patients with suspected choledocholithiasis. METHODS: All of the patients had abdominal ultrasonography, endoscopic ultrasonography ~and endoscopie retrograde cholangiography within 72 hours and final diagnosis was determined by endoseopic retrograde cholangiography with sphincterotomy. RESULTS: (l) Choledocholithiasis was confirmed in 45 patients: Thirteen patients had nondilated common bile ducts and 20 patients had stones with diamerer < 1 cm. (2) Endoscopic ultrasonography was more sensitive(95.5%) than abdominal ultrasonography (44.4%: P<0.0001) and similar to endoscopic retrograde cholangiography (97.8%). Specificity was same as 100% in 3 diagnostic tools. (3) Endoscopic ultrasonography was superior to abdommal ultrasonography for the diagnosis of choledocholithiasis with nondilated common bile duct(100% vs 15.3%, P<0.0001) and with less than 1cm sized small stone(100% vs 10.0%, P<0.0001). Endoscopic ultrasonography results did not depend on stone diameter or common bile duct dilatation. CONCLUSIONS: Endoscopic ultrasonography could be an accurate and safe diagnostic tool for the diagnosis of choledocholithiasis and could be promising especially in the cases with difficult cannulation of bile duct and gal1 stone pancreatitis.
