쪽(Polygonum tinctortium) 세포에서 외래 단백질 발현을 검토하기 위하여 green fluorescent protein(GFP)가 내재하는 pCAMBIA1302를 형질 전환시켰으며 Western blot 분석에 의해 GFP의 발현을 확인하였다. Sodium butyrate가 GFP생성에 미치는 효과를 검토한 결과, 10 mM에서 세포성장이 지연되었으며, 15 mM 이상에서는 정지되었다. 세포 내 GFP 생성량은 세포 접종 후 3일째 5 mM sodium butyrate를 첨가하였을 때가 0일째 처리에 비해 120% 증가하였다. 또한 접종후 3일 후 5 mM의 sodium butyrate를 처리한 경우가 10 mM의 경우보다 GFP의 수율이 50% 증가하였다. 본 실험을 통하여 세포 접종 후 3일째, 5 mM의 농도로 처리한 sodium butyrate가 외래 단백질의 발현을 효과적으로 증가시키는 결과를 확인하였다. To examine the expression of foreign protein in Polygonum tinctorium cells, plasmid pCAMBIA1302 encoding Green Fluorescent Protein(GFP) was used to transform the cells and the expression was confirmed using Western blot analysis. When the effect of sodium buryrate on the formation of GFP was examined, cell growth was retarded at the addition of 10 mM and was stalled at more than 15 mM. The amount of GFP production was increased by 15% when 5 mM of sodium butyrate was added at three-days after inoculation as compared to at 0-day. Moreover, when sodium butyrate was added at three-days after inoculation, the amount of GFP was increased by 50% at the addition of 5 mM of sodium butyrate as compared to 10 mM.

Hepatocellular carcinoma (HCC) is one of the most common malignant neoplasms occuring worldwide. Surgical resection currently provides the best chance of long-term tumor free survival, but the most HCCs are not candidates for surgical excision due to poor liver function or poor medical background. Numerous noninvasive alternatives to surgical resection have been introduced to treat liver cancers. Radiofrequency thermal ablation has begun to receive much attention as an effective and minimally invasive technique for the local control of HCC. The biliary system related complications after radiofrequency ablation has rarely been reported. We report a case of biliary-duodenal fistula with liver abscess after radiofrequency ablation for HCC. The case was treated by abscess drainage and antibiotics. (Korean J Gastroenterol 2008;51:199-203)

This is a clinical, retrospective review of 66 cases of the Adenoid cystic carcinoma who were treated at the Department of Surgery, Presbyterian Medical Center, Chonju during the past 20 years from January, 1971 to December, 1990. The results were obtained as follows; 1) The most common malignant tumor in the minor salivary gland was adenoid cystic carcinoma and it's incidence was 57.6% (38 cases). 2) The most common site of adenoid cystic carcinoma in the major salivary gland was parotid gland with the incidence of 22.7% (15 cases). 3) The peak age of patients with adenoid cystic carcinoma was 5th decade(30.3%) and others' peak age except adenoid cystic carcinoma was 6th decade(35.9%). 4) The duration of symptoms of adenoid cystic carcinoma patient was less than one year in the minor salivary gland, comprising 21 cases(55.3 %) and more than one year in 18 cases(64.9 %) of the major salivary gland carcinoma. 5) According to histologic grades of 66 cases of adenoid cystic carcinoma, Grade I was 15 cases and Grade II 19 cases, Grade III 5 cases. Other 27 cases were undetermined. 6) The incidence of cervical lymphnode metastasis of 39 cases of adenoid cystic carcinoma classified into histologic grades was 0% in Grade I, 10.5% in Grade II and 20% in Grade III. 7) The incidence of nerve invasion confirmed histologically was 20% in Grade I, 63.2% in Grade II and 100% in Grade III. It was significant(p<0.01). 8) The local recurrence rate was 26.7% in Grade I, 47.4% in Grade II and 60% in Grade III. The lung was the commonest site for distant metastasis comprising 14 cases among 19 cases in which distant spread occurred. 9) 5 year determinate disease-free survival rate according to the histologic grade was 57.1% in Grade I, 27.33 in Grade II and 25.03 in Grade III. 10) The determinate 5-year survial rate of adenoid cystic carcinoma was 71.4% in the only curative surgery group, 70.6% in the combined treatment group of surgery and postoperative irradiation, 66.7% in the combined treatment group of surgeη with postoperative irradiation and chemotherapy, and 33.3% in the non-curative treatment group. 11) The average size of tumor was 3.6cm in Grade I, 4.8cm in Grade II and 4.5cm in Grade III.
