Two cases of vertebra plana due to eosinophilic granuloma were experienced and successfully treated by anterior fusion of the involved spines at the department of Orthopedic Surgery in Seoul National University Hospital. Literature on the subject was reviewed.

Long term follow-up study was done on 38 cases of anterior fusion for spinal tuberculosis especially about effect of buttress graft. The average follow-up period was 16 months. 14 cases of effective buttress group were appeared' to achieve more rapid bony union and prevent further kyphosis or lateral wedging of the involved vertebral body than inadequate buttress group of 7 cases.

Toward the beginning of the twenty-first century, the world experiences the dramatic changes in politics, economics and culture, and it is evident that the Korean medical field will not be able to survive provided it doesn't prepare ourselves to adapt to those changes. The Korean Medical Society held a forum for the active operation of the medical society, inviting several leading affiliated societies, to meet the needs of the times. This review describes the summary of the presentation that the authors made on behalf of the Korean Radiological Society in the forum, including the organization, current status of academic activity, current status of international communication, and problems encountered in the internationalization of the Korean Radiological Society.

C-erbB-2 oncoprotein has been known to act as growth factor receptor responsible for the regulation of cellular growth, proliferation and differentiation and has been demonstrated in a number of cancers by immunohistochemical as well as matrix blotting techniques. Breast and ovarian cancer patients, whose tumor cells have amplification or overexpression of this oncoprotein, have been suggested to have worse prognosis. Yet, there are only a few studies on c-erbB-2 oncoprotein expression in transitional cell carcinoma(TCC) of the bladder. The aim of this study was to examine c-erbB-2 oncoprotein expression in bladder cancer to assess its potential as a useful prognostic marker in transitional cell carcinoma of the bladder. Deparaffinized tumor specimens from 42 patients with TCC of the bladder and 3 normal bladder tissue specimens were utilized. C-erbB-2 oncoprotein expression was detected by immunohistochemical analysis and then correlated with conventional prognostic variables such as histologic tumor grade, stage and DNA ploidy. In addition, we related the expression of c-erbB-2 oncoprotein to indicators of cellular proliferative activities such as proliferating cell nuclear antigen(PCNA), mean number of silver nucleolar organizer regions(AgNORs) per nucleus, flow cytometric S-phase fraction(CPF) and proliferation index(PI). The incidence of c-erbB-2 oncoprotein expression in Ash grade IV TCC of bladder was higher than that in Ash grade II and III (Chi-square test, p<0.05). The incidence of positive immunoreaction was higher in cases with muscle invasion and metastasis than in superficial tumors with statistical significance(p<0.05). In addition, statistical significant correlation was noted between c-erbB-2 oncoprotein expression and PCNA expression rate. But there were no significant differences in c-erbB-2 oncoprotein expression to DNA ploidy, PI nor SPF by flow cytometry and mean number of AgNORs per nucleus. The results of this study suggests that the c-erbB-2 oncoprotein together with other predictive parameters may serve to provide a phenotypic profile which permits more accurate forecasting of bladder cancer behavior and may prove to be useful in the future as an important guide to specific anti-tumor therapy.

The common bile duct and the duct of Wirsung cojoin at the level of the duodenum, forming the major. papilla of Vater. Existence of a double major papilla, i.e., two neighboring independent papillary structure:, is infrequent. In our endoscopy unit we have experienced one case of double papilla of Vater wherein canulation of the common bile duct and pancreatic duct could be accom plished through either orifice independently.

The authors evaluated high resolution computed tomographic (HRCT) findings of the isolated rabbit lungs with paraquat poisoning, and the findings were correlated with pathologic specimens. The purposes of this study are 1) to obtain the HRCT findings of the normal rabbit lung, 2) to find out if pulmonary pathology can be induced in rabbits by paraquat, and 3) to correlate the HRCT findings to those of pathology. Thirty rabbits were divided into three groups: group I included four control rabbits; group II included 16 rabbits given paraquat intraperitoneally(IP group); and group III included 10 rabbits given paraquat intravenously(IV group). The rabbits were sacrificed seven, 10 and 14 days after injection of various amount of paraquat, and then the lungs were isolated for HRCT and pathologic studies. Gross and microscopic findings of the three groups of control and paraquat-injected rabbit lungs were correlated with HRCT findings. Pulmonary congestion, mild thickening of alveolar walls and septae, and multifocal micro-atelectasis were the main pathologic findings of the lungs in both groups of the rabbits. Pulmonary hemorrhage was noted in five (31%) of 16 rabbits of IP group and three (30%) of 10 IV group. Pulmonary edema was seen in one rabbit (6%) of IP and four (40%) of IV group. Typical pulmonary fibrosis was seen in one rabbit of IP (6%) and IV (10%) group, respectively. There was no correlation between the amount of paraquat and frequency of the pulmonary pathology. Pulmonary fibrosis was seen at least one week after the paraquat injection. On HRCT, pulmonary hemorrhage and edema appeared as diffuse air-space consolidation and pulmonary fibrosis as linear or band-like opacities. However, minimal changes such as mild congestion.
