In this study we compared these markers in sera from patients with malignant and benign digestive tract diseases. METHODS Using a side-phase radioimmunoassay,CA50 and CEA serum levels were measured in 33 control subjects and 86 patients with gastric cancer(n=34),gastric ulcer(n=27)and chronic atrophic gastritis(n=25).Carcinoma of the stomach was found in the antrum(n=22),in the body(n=3),and the fundus(n=9),and histopathologically,was divided into adeno- carcinoma(n=21),squamous cancer(n=4)and not divided (n=9).Gastric ulcer,when present,appeared in the antrun(18 patients),the body(3)and the fundus(9)and chronic atrophic gastritis was all associated with intestinal metaplasia(IM). RESULTS The normal ranges established for CA50 and CEA in the control group were 16.26+6.14 kU/L and 3.12±1.03/μg/L respectively.In the patients with gastric cancer,serum levels of CA50(112.67±38.36 kU/L)and CEA(10.28±3.76μg/L) were elevated significantly(P<0.01,respectively),the former being>22 kU/L in 18 of 34 patients(53%;range,5-1 550 kU/ L),and the latter>5 μg/L in 19 of 34 patients(55.8%,range, 0.5-17.4 μg/L).A statistically significant correlation was found between the levels of CA50 and GEA(r=0.648,P<0.01). The serum levels of CA50(46.4±25.9 kU/L,P<0.01 )and CEA(6.85±2.43 μg/L,P<0.01)were much lower in patients with gastric ulcer or chronic atrophic gastritis(P>0.05). CONCLUSIONS Based on these results,it is concluded that CA50 and CEA are indicators for advanced gastric cancer,and af- ter surgery,their serum levels may decrease considerably. Overall,there is such a close correlation between them that in clinical practice they might be of great value to the diagnosis of gastric cancer.展开更多

METHODS： A retrospective analysis of data was per- formed on consecutive patients who underwent perito- neoscopic and abdominal computed tomography （CT） evaluations. Among 75 patients at the Seoul National University Hospital from January 2000 to June 2010 who underwent both tests, 27 patients （36.0%） and 25 patients （33.3%） were diagnosed with TBP and PC, re- spectively. Diagnosis was confirmed by peritoneoscopic biopsy. RESULTS： Serum c-reactive protein （7.88：1：6.62 mg/ dL vs 3.12 ＋ 2.69 mg/dL, P = 0.01）, ascites adenos- ine deaminase （66.76：1：32.09 IU/L vs 13.89 ：l： 8.95 IU/L, P 〈 0.01）, ascites lymphocyte proportion （67.77 ：1： 23.41% vs 48.36 ＋ 18.78%, P 〈 0.01）, and serum- ascites albumin gradient （0.72 ＋ 0.49 g/dL vs 1.05 ＋ 0.50 g/dL, P = 0.03） were significantly different be- tween the two groups. Among tumor markers, serum and ascites carcinoembryonic antigen, serum carbohy- drate antigen 19-9 showed significant difference be- tween two groups. Abdominal CT examinations showed that smooth involvement of the parietal peritoneum was more common in the TBP group （77.8% vs 40.7%） whereas nodular involvement was more common in the PC group （14.8% vs 40.7%, P = 0.04）. From receiver operating characteristic （ROC） curves ascites adeno- sines deaminase （ADA） showed better discriminative capability than tumor markers. An ADA cut-off level of 21 IU/L was found to yield the best results of differ- ential diagnosis; sensitivity, specificity, positive predic- tive value, and negative predictive value were 92.0%, 85.0%, 88.5% and 89.5%, respectively. CONCLUSION： Besides clinical and radiologic findings, ascitic fluid ADA measurement is helpful in the differen- tial diagnosis of TBP and PC.展开更多

The in vivo antitumor activity of the methanol extract of plant Lactuca serriola was evaluated at （100 mg/kg and 200 mg/kg of hole plant and 200 mg/kg, 400 mg/kg of fruit bw） against EAC using mean survival time. After administration of the extracts of Lactuca serriola, viable EAC cell count and body weight in the EAC tumor hosts were observed. The animal was also observed for improvement in the hematological parameters （e.g., hemoglobin content, red and white blood cells count and differential cell count） after treatment of plant extract. Intraperitoneal administration of plant extracts reduced viable EAC cells, increased the survival time and restored altered hematological parameters. Significant efficacy was observed for fruit extract at high concentration 400 mg/kg dose （P 〈 0.05）. It can be concluded that the methyl extract ofLactuca serriola possesses significant antitumor activity.展开更多

文摘To evaluate the antitumor activity of Lactuca serriola against EAC （Ehrlich ascites carcinoma） in Swiss albino mice. The in vivo antitumor activity of the methanol extract of plant Lactuca serriola was evaluated at （100 mg/kg and 200 mg/kg of hole plant and 200 mg/kg, 400 mg/kg of fruit bw） against EAC using mean survival time. After administration of the extracts of Lactuca serriola, viable EAC cell count and body weight in the EAC tumor hosts were observed. The animal was also observed for improvement in the hematological parameters （e.g., hemoglobin content, red and white blood cells count and differential cell count） after treatment of plant extract.
