Enterotoxigenic B. pagilis (ETBF) strains which produce a 20 kDa zinc metalloprotease toxin (BFI) have been associated with diarrheal disease of animals and young children. Using B. pngilis toxin gene (bfi) from strain 86-5443-2-2 (piglet isolate) as a probe, the gene was identified in 74/77 human and animal ETBF strains but only 2/97 non-toxigenic B. fragilis (NTBF) strains. The region flanking bp was mapped with several restriction enzymes and 8 resriction fragments aacent to bft were used to probe colony blots of 77 KTBF and 97 NTBF strains. All 74 bft-positive ETBF strains hybridized to the 8 probes spanning a ca. 18 kb chromosomal region; however, this 18 kb region was absent in the 3 ETBF strains lacking p, and 47 of the 97 (48%) NTBF strains lacked the entire 18 kb region. Of note, the 2 NTBF strains containing btf did not have a ca. 12 kb region upstream of btfp. A ca. 9 kb fragment flanking the btf gene has been sequenced. Analysis of this data revealed several open reading frames (ORF) of which 3 are of particular interest (ORFs 1, 2 and 3). ORF1 and ORF3 encode proteins with significant homology to mobilization proteins, and ORF2 encodes a protein with significant homology to metalloprotease proteins, but only 50% similarity and 30% identity to BFf. These results suggest: 1) the btf genes are flanked by at least 18 kb of DNA largely unique to ETBF strains indicating a putative pathogenic island, 2) another metalloprotease protein present in ETBF strains may contribute to the pathogenicity and variable virulence of these diarrheagenic strains and 3) the pathogenic island may be mobiTized among different Bacteroides strains, and possibly among different species of intestinal bacteria.

A clinical study was done on 43 patients witb basal cell carcinoma encountered in the Department of Dermatology, Busan National University Hospital during the past 10-years period frorn January 1968 to December 1977. Tbe results were summarized as follows: 1) Of 43 patients, 15 ceses were male and 28 cases were female with ratio of 1: 1.87. 2) Age incidence ranged frorn 15 years to 87 years with the highest incidence rate in the age group 40-49 years and incidence rate increased remarkbly in numlxr after over 40 years of age. Average age was 55 years. 3) The most common site was face occuring in 39 casts(90.7%), comprising 18 cases on nose, 12 cases on eyelids, 6 cases on cheeks, each 1 case on forehead, upper lip and auricle. 4) Noduloulc rative lesion was most common, otscrved in 29 cases(67.4%), nodular lesion in 9 cascs(20.9%), and pigmented lesion in 5 csses(11.6%). 5. The ratio of basal cell carcinoma was 1:1.2. 6) Three cases of precancerous states including 2 cases of xeroderma pigmentosa and 1 case of irradiated skin lesion were observed.

The authors studied thirty-three cases of malignant tumors of the skin (24 squamous cell carcinomas, 6 basal cell carcinomas, 2 Paget's diseases and one malignant melanoma) at the department of dermatology, Pusan national university hospital during the period from 1966 to 1971. The results obtained were summarized as follows: 1) There were 21 men(63.6%) and 12 women(36.3%) in this series. 2) The average age of these patients was 56 years with a range of 33 years to 70 years. 3) The ages at onset ranged from 29 to 66 years with the peak incidence in the 50-59 years group. 4) Of the 33 cases, 28 cases were first diagnosed at the age of over 40 years. 5) The ratio of squamous cell carcinoma versus basal cell carcinoma was 4: l. 6) In 29 patients the tumors occurred on the exposed areas of the body and the most common predilection site was on the face (63.6%), of which 6 squamous cell carcinomas occurred on the upper lip. 7) Of the 30 cases of both squamous cell carcinomas and basal cell carcinomas, 20 cases (66.6%) showed ulcerative lesions measuring from less than 1cm to 10cm in diameter. 8) Two cases of the tumors (one squamous cell carcinoma and one malignant melanoma) showed metastasis at the time of diagnosis. 9) The accuracy of clinical diagnosis in this series was 96%. 10) Of the 24 cases of squamous cell carcinomas, 7 cases were treated with radiotherapy, 5 cases with curettage and electrodesiccation followed by radiotherapy. Four squamous cell carcinomas and two basal cell carcinomas that showed relatively superficial and small lesions measuring less than 1.5cm in diameter were treated with electrodesiccation and curettage and are under observation with favorable results for six months to two years.

Clinical studies on five patients with acrodermatitis enteropathica visited during the period from March 1968 to September 1970 to the department of dermatology, Pusan national University hospital were made and the results obtained were summerized as follows; in addition, the literature was reviewed. 1) All of 5 patients aging from 3 months to 3 years, showed characteristic distributions of the cutaneous lesions which ranged in character from vesicobullous to heavily scaled psoriasiform and moniliasis-like lesions. 2) Of these, the nearly full clinical pictures were presented in two cases with the gradual onset in early infancy, dermatitis predominantly involving the periorficial areas and extremities, which followed by recurrent attacks of greenish yellow-colored diarrhea, partial and diffuse loss of the scalp hairs, stomatitis and monilial infections, whereas the rest thtee cases seemed to be "forme fruste" of this disease with the absence of hair and nail abnormalities. 3) There found no speeific histologic findings in two biopsies performed but showed somewhat the pictures of sub-acute dermatoses. 4) Candida albicans were demonstrated from the skin lesions in two cases, 5) Treatment with local application of gentian violet solution, nystatin ointment for the skin lesions and stomatitis were temporarily favorable in all cases and in case 1 and 5, diodoquin, each 300mg and 600mg were administered orally in divided doses for two weeks, with the result of satisfactory responses. However, the latter died, on the 3rd hospitalized day, of acute glomerulonephritis and upper respiratory infection. 6) Though it is generally accepted that there is definite familial occurrence in this disorder but we recognized no evidence of familial incidence in our five cases.

Two cases of toxic epidermal necrolysis (Lyell) appearing on 69-year old male and 12year-old female were presented. The clinical manifestations of toxic epidermal necrolysis developed after oral administration of novaquing for common cold. The cause of the disease was probably due to novaquing (phenobarbital and sulpyrin). The 69 year-old male was expired despite intensive treatment with fluid and electrolytes, antibiotics, corticosteroids, vitamins, and topical measures, but 12 year-old female was cured successfully with treatment.

Pyoderma gangrenosum, as described by Brunsting and his aaaociates in 1930, is characterized by the rapid appearance of one or more bluish-black, boggy, undermined ulcers, most frequently on the legs of peraons with ulcerative colitis or rheumatoid arthritis. Its pathogenesis is often obscure. Present management of pyoderma gangrenosum consists of local treatment of the wound, systemic cortieosteroid therapy, and treatment of any underlying disease. In our 21 year-old male with pyoderma gangrenosum, hyperbaric oxygen therapy was performed. Treatment was given in the hyperbaric oxygen one-man chamber at 3.0 ATA for 30 minutes daily for 49 days. By 36 days, the ulcers on the face and neck was healed. Approximately one month after the patient was discharged, complete resolution of the 1esions on the back occurred.
