PURPOSE: The purpose of our study was to characterize the enhancing patterns of hepatic metastasis from gastric adenocarinoma using multi-phase incremental bolus dynamic CT with obtained both in early and late phase contrast scan and to evaluate the its advantages. METHODS AND MATERIALS: Of 33 cases of multi-phase incremental bolus dynamic CT with proved hepatic~metastasis from gastric adenocarinoma, we classified dynamic enhancement patterns as three types according to early phase contrast enhancement, and then analized the late phase contrast enhancement, more metastasis detection, segmental abnormal arterial perfusions and correlation between pathologic type. RESULTS: Type I (totally hypodense lesion) was in 18 patients(55%), type II (peripheral high density area) was seen in 13 patients (39%), and type III (near totally hyperdense lesion) was seen in two patients(6%). But in late phase, masses showed totally hypodense area in 26 patients(79%), central high with peripheral low density area(PLDA) in six patients(18%) and totally isodense in one patient(3%). More metastatic masses were detected with early phase in 11 patients(33%) as compared with late phase contrast. Segmental arterial hyperperfusion around the lesions, which could represent intrahepatic portal branch invasion, was seen in 10 patients(30%). There was no correlation between pathologic type and enhancement pattern of lesions. CONCLUSION: Multi-phase incremental bolus dynamic CT could represent variable hemodynamic changes of hepatic metastatic masses and was useful to evaluate the qualitative and quantitative analysis of hepatic metastases.

Objective To investigate the distribution of weak D and Del phenotype in unrelated blood donors with negative Rh (D). Methods Four hundred and nineRhD (-) unrelated donors were screened by the saline agglutination method. Type weak D was detected by the indirect antiglobulin test, and type Del was detected by absorb radiation method. Results In 409 RhD (-) samples, 27 cases (6.61%) of type weak D were checked out, and 61 cases (14.91%) were type Del and 321 cases (78.48%) were corroborate for RhD (-), In the confirmed RhD (-) blood donors, phenotype ccee was most (49.14%), followed by Ccee (23.47%), People with phenotype ccEe accounted for 4.16%in type weak D, followed by Ccee (1.71%). Ccee accounted for 10.02%in type Del, and Ccee accounted for 1.71%. Conclusion RhD (-) donors screened by regular testing should adopt a more sensitive test for verifing type weak D or Del. In order to ensure the security of blood transfusion, people with type weak D and Del should be regarded as RhD positive blood donors, and the RhD negative people deemed to be recipients.

PURPOSE: To identify the longterm hemodynamics of various hepatic masses and to determine any differential findings by using postangiographic CT performed with increased amount of contrast media and time than conventional contrast CT. MATERIALS AND METHODS: 50 confirmed masses consisted of 22 hepatocellular carcinoma, 10 cholangiocarcinoma, 9 metastasis, and 9 cavernous hemangioma were included. The changes of the density of internal viable tumor portion relative to surrounding normal liver parenchyma in postangiographic CT from that in conventional CT were classified as 3 patterns; no specific changes, increase, or decrease. RESULTS: in 22 cases of hepatoceilular carcinoma, six cases showed no relative density change, four cases increase, and twelve cases decrease. In ten cases of cholangiocarcinoma, one case showed no change, nine cases increase. In nine cases of metastasis, four cases showed no change, five cases increase. In nine cases of hemangioma, all cases showed increase. CONCLUSION: In postangiographic CT which emphasize the significance of postequilibrium and delayed phase, other hemodynamic changes undetected in angiography could more easily be comprehended. Considering the differing amount of consumed contrast media and time duration, and with reference of other imaging modalities, differential diagnosis of hepatic masses based on longterm hemodynamics could easily be made.

The purpose of this study was to evaluate the existence of amoxicillin, clarithromycin, and metronidazole resistance Helicobacter pylori and to determine the in-vitro MIC of two and three kinds of antibiotic concominant administration in the isolates. The antimicrobial agents tested against 169 H. pylori included metronidazole, amoxicillin, ciprofloxacin, clarithromycin, omeprazole, josamycin, erythromycin, and tetracycline. MIC of each antimicrobial agents was determined by broth microdilution method. The 169 strains of H. pylori were isolated from biopsy specimens of patients with gastric cancer. MIC50 of clarithromycin, amoxicillin, metronidazole, omeprazole, erythromycin, josamycin, tetracycline, and ciprofloxacin was 2.0, 1.0, 4.0, 8.0, 0.5, 0.5, and 0.5 ug/ml, respectively. MIC90 of clarithromycin, amoxicillin, metronidazole, omeprazole, erythromycin, josamycin, tetracycline, and ciprofloxacin was 64.0, 64,0, 32.0, 16.0, 8.0, 2.0, and 1.0 ug/ml, respectively. H. pylori isolates were detected in the following resistaince rates: 34.3% to clarithromycin, 31.9% to metronidazole, 20.7% to amoxicillin, 12.4% to erythromycin, and 10,1% to josamycin. The prevalence of the antibiotic resistant strains of H. pylori were detected 18.1% for two kind of antibiotics and 9.6% for three kind of antibiotics, and 3.9% for four kind of antibiotics. The MIC90 of clarithromycin-, metronidazole-,and amoxicillin-resistant H. pylori was decreased under the 1 ug/ ml by the two or three kind of antibiotic concomitant administration in-vitro. These results suggest that two or three antibiotics concomitant administration could be more effective for the treatment of clarithromycin-, amoxicillin-, metronidazole-, and josamycin-resistant H. pylori strains.
