This experiment was carried out to determine the effect of the swine liquid manure separated its slurry on the dry matter yield, botanical composition and soil characteristics at pasture. The results obtained at National Livestock Research Institute(RDA), in Suwon from 1994 to 1997 are summarized as follows; The dry matter yields of swine slurry nitrogen 100%(T3), 75%(T4) and 50%(T5) were showed 94%, 91% and 75% of chemical fertilizer(T2)'s yield, respectively. and it was not significant difference between the yield of chemical fertilizer(T2) and swine liquid manure(50%)+chemical fertilizer(50%). According to application of swine liquid manure, the weed ratios of its plots were lowed by increasing its coverage and grasses. We conclude that the application of swine liquid manure(50%)+chemical fertilizer(50%) can be applied on grassland without adverse effect on dry matter production, quality of herbage, soil chemical properties.
Background/Aims: The effectiveness of curative therapy for Helicobacter pylori (H. pylori) infection may vary according to the eradication rate, side effects, and compliance of regimen. Lansoprazole, one of proton-pump inhibitor, has been claimed to have greater anti-H. pylori activity than that of omeprazole in vitro. However, there is no literature concerning the comparison of therapeutic efficacy of these two drugs in Korea. Thus, we investigated the efficacy of combination therapy with amoxicillin, metronidazole, and either lansoprazole or omeprazole. Methods: Eighty Patients with H. pylori infection were treated with one of four regimens: lansoprazole 30 mg UID, amoxicillin 1.0 g BID (LA); lansoprazole 30 mg UID, amoxicillin 1.0 g BID, metronidazole 250 mg TID (LAM); omeprazole 20 mg BID, amoxicillin 1.0 g BID (OA); omeprazole 20 mg BID, amoxicillin 1.0 g BID, metronidazole 250 mg TID (OAM), for 14 days. Results: The eradication rates were 33.3% in LA, 50.0% in OA, 76.5% in LAM and 83.3% in OAM. The most frequently observed side effect was diarrhea or loose stool. Conclusions: Low dose lansoprazole-based regimen showed comparable eradication rate, side effects and compliance, as compared with omeprazole-based regimen. Further study using lansoprazole at various doses may be needed to evaluate the efficacy of anti-H. pylori eradication regimens in Korea.
In this paper, we developed and implemented the geological magnetic filter for the improvements of the signal to noise ratio of the magnetic detection system. Using the geological magnetic filter, we can remove the coherent noises in the time domain and improve the signal to noise ratio of the magnetic detection system. Numerical simulation results show that geological magnetic filter can excellently remove the sensor misalignment effects and the regular short range local noise as well as it delete tile coherent noises. We confirmed that the geological magnetic filter improved the signal to noise ratio about 19dB and deleted the coherent noises with restoring the source magnetic signal through experiments by implemented system.
To evaluate the clinical usefulness of endoscopic retrograde biliary drainage (ERBD) in the treatment of malignant obstructive jaundice, we analysed 10 patients (common bile duct cancer; 8 patients, pancreas cancer; 1 patient and metastatic cancer; 1 patient) who underwent 14 procedures of ERBD from April 1988 to February 1989 at Yonsei Medical Center. The results were as follows. 1) The success rate for insertion of endoprosthesis was 78.6% (11 of 14 ERBD procedures). The causes of failure were failure of the endoscopic sphincterotomy due to a tumor of the ampulla of Vater in one patient and failure of introducing the guidewire beyond the stenosis in 2 patients. 2) The complications were hemorrhage (1 patient), fever (7 patients), increased serum amylase level (4 patients), cholangitis (5 patients), and sepsis (2 patients). Endoprosthetic complications included obstruction (4 patients) and migration (1 patient). 3) Average interval between the introduction of the endoprosthesis and obstruction was 64.8 days (21,59,82 and 97 days in each patient). 4) The total bilirubin was decreased at 7-14 days after ERBD, and then maintained at low level. 5) Of the 10 patients who received ERBD, 2 patients were lost to follow up, and 3 patients died due to sepsis. It was impossible to make conclusions about the survival time because of the short period of follow-up, however the survival time was longer in the patient treated by chemotherapy and radiotherapy (185 days) than in the patients treated by chemotherapy (range; 24-255 days, mean; 137 days) and by conservative measures (range; 10-81 days, mean 55 days). In conclusion, we thought that ERBD is a useful method of palliative treatment in malignant obstructive jaundice. However, the problem of obstruction of the endoprosthesis must be solved in the future.
