The gene encoding E7 oncoprotein of human papillomavirus type 16 was cloned and expressed in Escherichia coli, and the monoclonal antibodies (Mabs) against this expressed protein were generated. For the efficient immunization, two kind of recombinant E7 protein in fusion form were produced. One was maltose binding protein (MBP) fusion type (MBP-E7) and the other was T7 phage gene 10 product fusioa type (gene 10-E7). Immunization with these two fusion protein to mice, finally two Mabs (VD6 and IB10) were obtained. VD6 and IB10 showed reactivities with E7 protein in CaSki cell but not in HeLa by Western blot analysis. In addition, the Mab, VD6, reacted with COS-7 cell transfected with E7 gene majorly in cytoplasm by immunofluorescence test. Also VD6 could detect E7 protein in cytoplasm and nucleus of CaSki ceU by immunogold electron microscopy. Based on these results, the Mab VD6 was could be used for various E7 detection system such as Western blot analysis and immunohistochemical methods.

A total of 601 anesthesias given to the patients over age 60 who were admitted to Han Gang Sung Shim Hospital during the period from Jan. 1976 to Dec. 1980, were subjected to this clinical review. 1) Of the total 15,609 cases, 601 cases(3.8%) were over 60 years of age consisting of 315 male(52.4%) and 286 female(47.6%). 2) Among the 601 geriatric patients, 453 cases were 60~69 years of age(75.4%), 128 cases were 70~79 years of age(21.3%) and 20 cases were over 80 years of age(3.3%). 3) In the surgical group, 358 cases(59.7%) were general surgery, 120 cases(20.0%) were orthopedic surgery, 34 cases(5.6%) were urology, 20 cases(3.3%) were gynecology respectively. 4) The techniques of anesthesia were 545 cases(90.7%) of general anesthesia, 22 cases(3.7%) of spinal anesthesia and 17 cases(2.8%) of axillary block. 5) Anesthetics were diethly-ether 24 cases(36.3%) and halothane 22 cases(33.3%) in 1976. But there were 5 diethly-ether cases(0.3%) and 120 halothane cases(91.6%) in 1980. 6) For the duration of anesthesia, 81 cases(13%) were within 1 hour, 238 cases(39.6%) within 2 hours, 156 cases(26.0%) within 3 hours and 21 cases over 5 hours. 7) In the classification of physical status of the geriatric patients, 42 cases(7.0%) were class l, 201 cases(33.2%) were class ll, 109 cases (18.1%) were class lll and 8 cases(1.3%) were class lV. 8) Emergency cases were 223 cases(37.1%) and 378 cases(62.9%) were elective. 9) The findings of preoperative chest X-rays revealed that 227 cases(48.8%) were within normal limits, 56 cases(12.0%) had hypertensive heart disease, 24 cases(5.1%) had senile fibrosis, 22 cases(5.1%) had unstabilized tuberculosis and 14 cases(3%) had pneumonis. 10) In the preoperative R.K.G., which covered 50% of the patients, 115 cases(38.3%) were within normal limit, 41 cases(13.6%) showed L.V.H., 30 cases(10.0%) had sinus bradycardia, 13 cases (4.3%) had myocardial lschemia and 7 cases(2.3%) had R.B.B.B. 11) Post-operative mortality rate was 5.8% in 1976, 4.0% in 1977, 3.6% in 1978 and 2.1% in 1980, and over all mortality rate was 3.1%.

The plasminogen and plasmin system, which is mainly regulated by urokinase-type plasminogen activator (uPA), its receptor (uPAR) and its inhibitor (PAI-1), is generally believed to play a role in cancer invasion and metastasis. This study was conducted to investigate the role of uPA, uPAR and PAI-1 in the invasion and metastasis of gastric adenocarcinoma. The expression of mRNAs for uPA and PAI-1 was determined by Northern blot analysis in nine primary gastric cancer tissues, nine paired metastatic lymph nodes and normal gastric mucosa. The mRNA of uPA was not or faintly detected in normal mucosa, while the expression was increased in both primary gastric cancer tissues and metastatic lymph nodes to a similar degree. The mRNA expression for PAI-1 in the gastric cancer tissues was not different from that in the paired metastatic lymph nodes and normal mucosae. uPAR was determined by immunohistochemical staining, demonstrating that five (56%) and six (67%) out of nine primary gastric cancer tissues and nine paired metastatic lymph nodes were positive, respectively and the intensity was stronger in metastatic lymph nodes. The results support the concept that most gastric cancer cells may have an innately moderate level of uPA and uPAR, and that increase of uPAR expression can be considered to be closely associated with cancer invasion and metastasis.

We investigated the correlation between Cyclooxygenase-2 (COX-2) expression and the tumor response in patients with cervical cancer that were treated with curative radiotherapy (RT). Fifty-seven patients with squamous cell carcinoma were treated with concurrent radiochemotherapy (CRCT, n=29) or RT alone (n=28). The response of each patient was evaluated by three serial Magnetic Resonance Imaging examinations: before the start of RT, at four weeks after the start of RT (mid-RT) and at four weeks after the completion of RT (post-RT). Forty-three patients had positive COX-2 expression. The COX-2 negative patients achieved a higher rate of complete response (CR) at mid-RT than did the COX-2 positive patients (28.6% vs. 7.0%, P=0.054), but not at post-RT (64.3% vs. 69.8%). The initial tumor volume was a significant predictor of CR at mid-RT (P=0.003) and post-RT (P=0.004). The multivariate analysis showed that the initial tumor volume (at mid-RT and post-RT) and CRCT (at post-RT) were significant predictors of CR; however, the COX-2 expression was not. In conclusion, the COX-2 expression status has no significant correlation with the tumor response. Further studies on the changes in COX-2 expression levels during RT may be helpful for determination of its role in the tumor response to treatment and patient prognosis.
