N/A We evaluated the usefulness of serum urea and creatinine ratios to differentiate bleeding sites in 63 patients vith gastrointestinal bleeding from August 1991 to Viay 199Z, The follow- ing results were obtained: Serum urea and creat.inine ratios in the upper gastrointestinal group were significantly higher than those in t.he lower gastrointestinal bleeding and control. The ratios were higher in proportion to the volume of blood loss in the upper gastrointestina! Bleeding group. The percent of patients over 80 in the ratios was 77 % in t.he uppcr gastrointestinal bleeding gr oup, whereas was 6.2 % in the lower gastrointestinal bleeding. Thc upper gastrointestinal bleeding, the ratios below 80 were obtained in 11 cases which ha<l cases of small amount bleeding, shortening of intestinal transit tirne, correction of body I'luid arid electrolyte imbalance, and other unknown causes. Result,s of above studies indicated that de terrnination of serum urea and creatinine ratios was a simple and useful procedure fr diagno sis, but we need further study t.o det,ermine the presence of factors to the rat.io variability.(Ko rean J Gastroenterol 1994; 26: 432 436)

The performance response when lactating cows were fed high level feeding of corn silage. as a only roughage, were studied in reprications of a 3×3 Latin square design, each treatment represents 3 cows. The 9 cows from 3 treatments that is 3 different corn silage levels were fed for 16 day's main experiment period following 10 day's preliminary period. The corn silage feeding levels were. (A) Basal ration with corn silage of 3% of body weight, (B) Basal ration with corn silage of 8% of body weight. (C) Basal ration with corn silage of 10% of body weight. The result of this study shoved a summary as follows. 1. There was no significant difference among 3 different levels of corn silage feeding in milk production. The production index was 100 for treatment A. 87 for treatment B and 90 for treatment C. However, there was a lute difference in butter fat content with the index of 100 for treatment A. 99 for B and 95.5 for C respectively. 2. In body weight change, There was no difference among 3 treatments, but slight difference occurred between B and C treatments without statistical significance. 3. The ketone body contents in urine was tested, there was no significant level was founded by feeding of high level of corn silage for lactating dairy cows.
