From the leprosy patients hospitalized at the Korean National Leprosarium on Snrokdo Island, forty-five leprosy patients with plantar ulcers were selected randomly for microbiological studies. A total of 84 strains of bacteria, with the most common being Neieseria sicca (25 strains: 29.8%), 34 strains (40. 5%) were present as a pure growth and 50 strains (59. 5%) were present in ulcers with multiple infection. Antibiotic susceptibility tests indicated that bacterial isolates were rather highly susceptible to gentarnicin and kanamycin, but varying degree of isolates were resistant to 12 antibiotics including streptomycin, rifampicin, lincomycin, penicillin, terramycin and colimycin etc. From a total of 30 plantar ulcers, 17 ulcers produced 24 strains of fungi and 1 strain of Balanticlium coli. They consisted of 17 strains of saprophytic fungi (70. 8%) and 7 strains of yeast-like fungi (29. 2%). Of the culture media for Balantidium coli, Sabourauds glucos medium is the most specific and selective that the author found.

Vibrio vulntficus is a halophilic, gram-negative, motile, marine rod tha is capable of causing rapidly progressing, life-threatening infection in human. The illnesses associated with this organism can be categorized clinically as four groups such as wound infection, primary sept cemia, gastrointestinal illness, and other infection. The clinica1 manifestation of patients with primarys pticemia can vary from fever and chills alone to a more severe illness including secondary skin lesions, multisystem organ failure and shock. Several skin lesions are found in patients with this septicemia, including edema, blister, gangrene, localized swelling, and papura and, less comrnonly, cyanosis, maule and patch, papule, wheal, and pustule. The cutaneous lesions appear mostly on the legs. The hist pathologic findings differ according to the clinieal stage(inflammatory, bullous, and gangrenous) of the lesions. Mortality is very high. The organism is isolated mostly from skin lesion and/or blood. Vibrio vulnifices is sensitive to chloramphenicol, gentamicin, tubramycin, tetracycline, and 3rd generation cephalosporins. Most cases occur during the summer montlis, in men and in person 40 or more year of age. The illness begin with septicemia, often within 2 days of the consumption of various kinds of raw seafood such as fish, shell- fish, and brown seaweed. Patierts frequently have preexisting liver diseae and/or alcohol abuse. For prevention of Vibrio vulni ficus infections, persons with liver diseases or alcohol abuse should avoid consuming or handling raw seafood. Clinicians should start appropriate therapy promptly in patients with chronic underlying disease and a recent history of raw seafood con umption who present with unexplained febrile illness.

PURPOSE: It is difficult to determine the activity of tuberculosis radiologically. Therefore there have been efforts to assess the activity using radiopharmaceuticals such as 67Ga, 99mTc-tetrofosmin, and 99mTc-MIBI. But there may be some discrepancy in defining the term 'activity' between clinicians and nuclear physicians. While negative conversion of sputum acid fast bacilli (AFB) is defined as 'disappearance of activity' by clinicians, a loss of uptake in previously positive lesion is accepted as 'disappearance of activity' by nuclear physicians. We designed a prospective study to see if the negative conversion of sputum AFB could directly match the disappearance of radioactivity of the lesion. MATERALS AND METHODS: Fifteen patients with bacteriologically confirmed active localized pulmonary tuberculosis were scanned 10 and 60 min after intravenous injection of 550 MBq 99mTc-MIBI. In 6 patients, who showed negative conversion of sputum AFB after 3-7 months of chemotherapy, 99mTc-MIBI scan was repeated. For the purpose of comparison, target/nontarget ratios of the lesions were determined. RESULTS: 12/15 (80%) patients with active pulmonary tuberculosis showed increased uptake of 99mTc-MIBI in tuberculous lesion. After negative conversion of sputum AFB, 5/6 (83%) patients still showed increased uptake, although the intensity of uptake decreased. CONCLUSION: Uptake of radioactivity decreased but did not disappear after negative conversion of sputum AFB. 99mTc-MIBI scan may be useful to address the degree of inflammation of pulmonary tuberculous lesion, but the uptake did not directly match the activity defined by positivity of sputum AFB. We nuclear physicians might have used the term 'activity' somewhat differently from clinicians who treat patients with tuberculosis.

Photosensitive psoriasis is a rare disease defined as psoriasis in which the lesions deteriorate or new lesions develop after sun exposure. It should be differentiated from other photosensitive conditions that may be a vated or confused on sun-exposure. Half of the patients have a history of polymorphic light eruption(PMLE), whieh several weeks later develops into psoriasis lesions and the others have no history of preceding PMLE reaction. PUVA therapy is recommended for the treatment of choice. In this report, we describe two cases of photosensitive psoriasis. A 51-year-old woman without underlying psoriasis suffered from erythemato-squamous papular lesions on the face, neck and dorsum of hands after sun-exposure. She revealed a lowered minimal erythema dose(MED) for UVA which was confused with a photosensitive disease. But characteristic psariatic plaques on the elbow, knee and palm and histologic findings made the diagnosis photosensitive psoriasis. She showed a good result to cyclosporine therapy. The other patient, a 44-year-old woman with underlying psoriasis, experienced an exacerbation with preceding PMLE and showed a lowered erythema threshold for UVB. She was treated with sun-screen and topical corticosteroids.

BACKGROUND: Vibrio vulnificus(V. vulnificus) is a pathogenic, marine, halophilic, Gram negative bacillus which causes fulminant infection in humans through skin wounds. or the ingestion of raw seafoods or Most cases are reported sporadically in summer in the south-western coastal area of Korea. OBJECTIVE: We studied the distribution of V. vulnificus in sea water, fishes, shellfish and sea mud from May to October in 1996 and the relationship between regional distribution and environmental factors. METHODS: We collected the sea water, sea mud, fishes and seafoods from May to October in Kunsan, Daechun, Moochangpo, Puan, Youngkwang and cultured it in Thiosulfate-Citrate-Bile salt-Sucrose(TCBS) agar, Cellobiose-Polymyxin B-Colistin(CPC) agar, and Sodium dodecyl sulfate- Polymyxin B-Sucrose(SPS) agar. At the same time we investigated environmental factors such as temperature, pH, salinity, turbidity, dissolved oxygen(DO), NO3 of sea water. RESULTS: Twelve strains(2.17%) of V. vulnificus were isolated from a total of 552 specimens. The V. vulnificas isolation rate from sea mud was higher than in sea water and shellfish. Areas where V. vulnipcus was isolated were Kunsan and Daechun. It was isolated during June, July and August. The Isolation rate was higher with CPC agar than TCBS, SPS agar. When V.vulnificus was isolated at Kunsan, the environmental factors of sea water noted were as follows: temperature, 25.3C; turbidity, 121Formazine turbidity units; salinity, 12.2%; DO, 7.3mg/L; pH, 7.37 and NO3, 1.18mg/L. CONCLUSION: CPC agar is the best medium of the three above used for the isolation of V. vulnificus from environmental samples. V. vulnificus was highly isolated in the Kunsan area because of the high water temperature and turbidity, low salinity and weak alkali state of the sea water in comparision with other areas. We suggest that high temperature and turbidity, low salinity and weak alkalinity of sea water are very important environmental factors for the growth of V. vulnificus.

Using the 15 strains of Vibrio eulnificus isolated from the blood and tissue fluid of the patients with primary septicemia, cultural characteristics were studied on various media. The media to be used in culturing Vibrio vulnificus should contain sodium chloride, because it could not survive on the media without NaCl. The organism grew poorly or not at all on the media with eosin-y, methylene blue, crystal violet, or azide, because these substances suppress its growth. Vibrio vulnificus grew well in the enrichment media such as brain heart infusion, tryptic soy broth, and nutrient broth with 0. 5% NaCl.

BACKGROUND: Form the 1970's calcium channel blockers have been used as one of the most effective drugs for antihypertensive therapy. Nilvadipine(Nivadil(R)) is a new vessel-selective calcium channel blocker with a markedly high oral bioaviliability and a long elimination half-life time. To evaluate the efficacy and side effects of nilvadipine, daily monotherapy was done in 22 patients with essential hypertension. METHOD: After more than 2 weeks of previous drug wash-out periods, Nilvadipine 8-12mg was administered daily in 2 or 3 divided dosage for 8 weeks in patients with mild to severe essential hypertension. The sitting blood pressure(BP) and heart rate were measured before and 2, 4, 8 weeks after medication. RESULT: Systolic and diastolic BP were significantly reduced at 2 weeks after medication and no further significant BP reduction were noted throughout the remainer of the trial(4 to 8 weeks). Normotension(diastolic BP < or =90mmHg) was achieved in 14 cases(67%) after 8 weeks therapy and in 7 cases(33%) BP reduced effectively. The side effect noted were headache and facial flushing in 2 cases and in one of them the medication were discontinued. And fatigue, dizziness were complaint in 1 case respectively. There were no significant laboratory changes before and after nilvadipine therapy. CONCLUSION: It can be concluded that nilvadipine(Nivadil(R)) monotherapy is effective in many patients with essential hypertension and a clinical study of combined therapy with other antihypertensive agents in larger numbers of patients will be needed.

Vibrio vulnificus is a halophilic gram-negative, marine bacterium which causes fulminating and potentially fatal human disease. A new sensitive and specific serogrouping procedure was developed for identifying V. vulnificus. Reference antis:ra(01-014) to V. vulnificus were prepared by vaccinated rabbits with heat-killed bacteria, and the antisera were examined whether erogrouping test will be available for rapid and sensitive identification method of V. vulnifiius or not. All of thirty-seven clinical strains tested were agglutinated with 5 kinds of aritisera such as 04A, 01, 013, 03, and 014. Of these serovar 04A was predominant(75.7%). The author investigated the correlation among certain serovars, consumed seafoods, and nortality rate to verify whether the serovar is of pognostic value. There was no significant orrelation among them. These results suggest theart serogrouping procedure could be of value in rapidly identifying V. vulnificus.

Patterns of branches and distribution of right coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. Generally the right aortic sinus had one orifice, but sometimes had two orifices which were related to conal branch. The right coronary artery had mural coronary in 17.5% of cases. In the most of the cases, right coronary artery was dominent, and type 4 was most frequent. Descending septal artery was observed in 17.5% of cases. The atrial branches can be grouped as anterior, posterior and left atrial, and each group was composed of one or two branches when present. In 97.5% of cases, intermediate atrial branch was observed. The sinuatrial nodal artery was originated mostly from right coronary artery. The atrioventriclar branch was observed in 7.5% of cases. The ventricular branches can be grouped as right anterior, right posterior and left posterior, and composed of 3-6, 0-2, and 0-4 branches respectively. Right marginal branch showed great variation, and other branch originated from superiorto to it was found to distribute the apex of the heart. Based on the results, the authors depicts typical arrangement of the rignt coronary artery in Korean.
