Abstract
During the past fifteen years, 44 patients with multicentric carcinoma of the esophagus or double primary malignant neoplasm of the upper alimentary tract, collected from 5316 patients with cancer of esophagus or gastric cardia in the same period, were treated in our hospital. The incidence was 0.83%. All were proven by pathology. Exploratory thoracotomy was done in 32 patients and 26 lesions were resected with a resection rate of 81.3%. All patients with cancer resected survived over 1 year, 6 out of 9 survived over 3 years and 2 out of 3, over 5 years. In the 18 patients who received chemotherapy alone, 12 were followed and all died within 1 year. It is shown that multicentric carcinoma of the esophagus or double malignant neoplasm of the upper alimentary tract should be given energetic treatment. Finally, the incidence, diagnosis criteria, diagnosis method, etiology and management are discussed with a review of literature.

Abstract
A polypeptide of 54-kDa molecular mass (p54) induced by molecularly cloned human interferon gamma (rIFN-gamma) in human amnion U cells was characterized biochemically and immunologically. Rabbit polyclonal antibody to p54 was prepared using p54 purified from human amnion U cells as the immunogen. As measured by immunoprecipitation of [35S]methionine pulse-labeled extracts or by immunoblot analysis of unlabeled extracts, the synthesis of p54 was greatly elevated in three human cell lines treated with IFN-gamma, amnion U, fibroblast GM2767, and fibroblast F153. Moreover, the rabbit anti-p54 polyclonal antibody preparation cross-reacted with cytoskeleton-associated polypeptides prepared from human cells and from sea urchin embryos. By use of a monoclonal antibody probe directed against the common domain of intermediate filaments (anti-intermediate filament antibody), it was established that intermediate filament components are also induced by rIFN-gamma. Anti-p54 polyclonal antibody cross-reacted with anti-intermediate filament antibody-recognized, rIFN-gamma-induced polypeptides. Thus, it appears that p54 may be an IFN-induced cytoskeleton-associated polypeptide.

Abstract
The cell line TBC-27, from a human bladder transitional cell carcinoma Grade II, was established and maintained for 8 months through 27 passages. TBC-27 cells have the epithelioid cell morphology during culture. The population doubling time of the 14th generation cells was 27 hours by growth curve. The chromosome karyotype of the 12th generation cells consisted mainly of hypodiploid (mode 40-45). Ultrastructurally, there was a great deal of freeribosome and vesicle in the cytoplasm and a great number of atypical microvilli on the surface of the 21st generation cells. The heterotransplantation test revealed that the xenografted tumor in the immunosuppressed suckling rats was similar to the initial bladder carcinoma in histology.

Abstract
Using the human liver cancer DNA transfected NIH/3T3 cell line, the human N-ras oncogene and the over expression of the oncoprotein P21ras was demonstrated, BALB/C mice were immunized. The spleen cells from the immunized mice were fused with SP2/0 myeloma cells. After the HAT medium selection and screening, two hybridoma cell lines, SCI-Oncogema 1 and 2, were established. In the immunoprecipitation test, the molecular weight of the protein reacting to Oncogema 1 was 21,000. This M.W 21,000 protein possessed the capability to bind with GTP, i.e. the character of P21ras. These data indicate that the Oncogema 1 is the monoclonal antibody against P21ras. Using Oncogema 1, specimens from 6 liver cancer patients were studied by immunopathology. With ABC stain, it was observed that the malignant cells in all the samples showed dark staining; the P21ras revealed over expression. Although the staining was heterogeneous, it implied that the ras oncogene was involved in the carcinogenesis of these six samples. No over expression was seen in the normal liver cells even in those around the cancerous lesion. However, dysplastic cells were moderately stained which means that the ras oncogene was activated and P21ras over expressed in these cells. The results suggest that the ras oncogene and P21ras play an important role in the early stage of liver cancer carcinogenesis.

Abstract
Thirty specimens from 30 patients with urologic and male genital system tumors were cultured. Eighteen (60%) showed initial cell growth. Four (13%) were successful in primary culture. In a renal cell carcinoma and a bladder transitional cell carcinoma, the subcultures were successful after the primary culture. In eight months, having transferred the former for twelve generations and the latter for twenty-seven generations, these two cell lines are established. The morphological characters of the cultured cells, eradication of fibroblasts, conditions of culture and prevention of contamination are discussed.

Abstract
Conventional assessment of antegrade (AV) and retrograde (VA) conduction involves stepwise increments in pacing rates until block in conduction is observed. This study was designed to establish the comparative characteristics of ramp pacing, in which the rate is continuously and smoothly incremented until block occurs. Two hundred and ten patients participated in portions of this study. Stepwise pacing was performed in 10 beat/minute steps, with the rate held for at least 15 seconds at each step; if marked prolongation or variability in conduction was observed, the rate was held constant for up to 60 seconds to allow for accommodation. With ramp pacing, the rate was gradually increased at a steady 2-4 beats/minute/second. Whenever possible, both stepwise and ramp pacing were performed for assessment of both antegrade and retrograde conduction. All patients had conducted sinus rhythm as their baseline mechanism. Antegrade conduction was similar using incremental stepwise and ramp pacing. The AH interval at a cycle length (CL) of 500 ms, the maximum AH increment, the cycle length at AV block were all remarkably similar (p = NS). Assessment of retrograde conduction produced similar results, with insignificant differences between maximum conducted VA intervals, and cycle length at VA block using the two pacing techniques. Ramp pacing provides a useful and rapid alternative to conventional stepwise incremental pacing in the assessment of antegrade and retrograde conduction in patients using both normal and accessory pathways. Ramp pacing was better tolerated, and some correlations between antegrade and retrograde conduction were stronger with the ramp pacing technique.

Abstract
The antihypertensive effects of intravenous injection of ketanserin, a 5-HT2 receptor antagonist, were assessed in conscious rabbits. In intact rabbits, ketanserin lowered blood pressure in a dose-dependent manner. The antihypertensive effects of ketanserin were also observed in rabbits with two-kidney, one clip (2K1C) hypertension and with one-kidney, one clip (1K1C) hypertension. The effect was more marked in the 1K1C rabbits with low plasma renin activity (PRA) and high plasma norepinephrine (PNE) than in 2K1C rabbits with high PRA and normal PNE. The heart rate was not changed. Ketanserin suppressed the pressor response to exogenous norepinephrine (0.6 micrograms/Kg) 15, 30 and 45 min after the injection of ketanserin (1 mg/Kg). It also suppressed the pressor response to phenylephrine (3 micrograms/Kg) 15 min after the injection, but it did not suppress the pressor response to angiotensin II (0.15 micrograms/Kg). In order to investigate baroreceptor function, balloons were placed around the abdominal aorta and the inferior vena cava and inflated alternately. Thus, the mean arterial pressure vs heart period-logistic curve was obtained under steady-state conditions. There were no changes after the drug administration in the range of heart period and the gain (the slope at midpoint of the curve). These results suggest that the inhibition of pressor response of norepinephrine has effects in addition to a direct vasodilatory action and that an alteration of baroreceptor function is not involved in the antihypertensive effects of ketanserin.
