The purpose of this study was to investigate the possibility of using the buffer index curve as a criterion of silage quality evaluation. The buffer index (or buffer capacity, $\beta$) value is the amount of 0.1N NaOH consumed in titrating from the beginning to the end of the chosen pH step. This value equals the slope of the titration curve at the chosen pH range (${\beta}={\Delta}NaOH/{\Delta}pH$). There were two patterns of buffer index curve. Poorly preserved silages had a peak at pH 5.0, whereas with well preserved silages the peaks tended to rise to the pH 3.75 or 4.00. Well preserved, wilted silages with high pH also appeared to have peak values at pH 3.75 or 4.00. There was a high positive correlationship between the concentration of lactic acid and peak value of good quality silage (r = 0.994, p < 0.01). Also a high positive correlationship (r = 0.899, p < 0.001) was found between the sums of concentration of acetic and butyric acids and the peak values of poor quality silages. The results of these experiments verified the value of the buffer index method as a criterion of silage quality evaluation.

$^{99m}TC,\;^{67}Ga,\;^{131}I,\;^{32}P$각각을 웅성백서에 투여하여 생체에 미치는 혈중 독성의 영향을 측정 비교하였다. 핵종의 투여량은 통상 인체에 주사되는 양을 기준으로하여 조절 하였으며 생화학적 반응 지표로 혈중 BUN, Creatinine, SGOT SGPT와 $PGE_2$의 활성도출 측정하였다. $^{99m}Tc$의 효과로 Creatinine의 변동은 없었으며 BUN, SGOT 및 $PGE_2$활성도가 투여 전에 비하여 증가된 경향을 보였으나 통계적 의의는 없었다. $^{67}Ga,\;^{131}I$ 및 $^{32}P$의 경우 BUN, SGPT 및 SGOT 에서의 증가는 임상적 의의는 없었으나 $PGE_2$는 정상치 보다 크게 상승 하였다. 한편 $^{238}U$이 가장 심한 독성을 나타내었다. 따라서 핵의학에서 이용되는 핵종의 방사성 독성의 효과를 평가할 경우 혈중 $PGE_2$의 측정법이 유용할 것으로 생각된다.

Purpose: Tumor recurrence is the principal cause of poor outcomes in remnant gastric cancer (RGC) after resection. We sought to elucidate the recurrent patterns according to tumor locations in RGC. Materials and Methods: Data were collected from the Shanghai Cancer Center between January 2006 and December 2020. A total of 129 patients with RGC were included in this study, of whom 62 had carcinomas at the anastomotic site (group A) and 67 at the non-anastomotic site (group N). The clinicopathological characteristics, surgical results, recurrent diseases, and survival were investigated according to tumor location. Results: The time interval from the previous gastrectomy to the current diagnosis was 32.0±13.0 and 21.0±13.4 years in groups A and N, respectively. The previous disease was benign in 51/62 cases (82.3%) in group A and 37/67 cases (55.2%) in group N (P=0.002). Thirty-three patients had documented sites of tumor recurrence through imaging or pathological examinations. The median time to recurrence was 11.0 months (range, 1.0-35.1 months). Peritoneal recurrence occurred in 11.3% (7/62) of the patients in group A versus 1.5% (1/67) of the patients in group N (P=0.006). Hepatic recurrence occurred in 3.2% (2/62) of the patients in group A versus 13.4% (9/67) of the patients in group N (P=0.038). Patients in group A had significantly better overall survival than those in group N (P=0.046). Conclusions: The tumor location of RGC is an essential factor for predicting recurrence patterns and overall survival. When selecting an optimal postoperative follow-up program for RGC, physicians should consider recurrent features according to the tumor location.

The purpose of this study was to test the effects of health contract on the performance level for activity of daily living(ADL) in the hemiplegic patients. A quasi - experimental research for health contract, which was approved as an effective method of nursing intervention, was attempted to increase the performance of the hemiplegic patients' ADL. As a purpose sample, 69 hemiplegic patients hospitalized at Oriental medicine hospital of K university were taken and devided into the experimental group and the control group by means of random assignment. After Contracting with the experimental group, they were reinforced everyday for 20 minutes. The experimental group and the control group were observed and interviewed for five times at the in terval of 3~4 days by the trained nurses for this research. The data Collected through above mentioned methods were compute analyzed by t-test and ANOVA according to the purpose of this study. The data collected through above mentioned methods were computer analyzed by t-test and ANOVA according to the purposre of this study. strate increased the performance level for ADL than the Control group” was supported(t＝2.96, df＝52.76, p＝ .004). Sub Hypothesis 1,2,4,5 : “The hypothesis that the experimental group with health contract will demonstrate increased the performance level for eating(t＝2.29, df＝42.70, p＝ .027), personal hygiene and grooming (t＝4.04, df＝43.10, p＝ .000), dressing(t＝3.32, df＝67, p＝ .001) and undressing (t＝3.47, df＝48.44, p＝ .001) than the control group” was supported. Sub Hypothesis 3.6 : “The hypothesis that the experimental group with health contract will demonstrate increased the performance level for toiletting(t＝ .19, df＝67, p＝ .849) and mobilization (t＝ .30, df＝67, p＝ .765) than the control group” was not supported. The conclusion can be that the positive relationship between the nurse and the patient results in the desired performance level for ADL in the hemiplegic patients.

This study was conducted to assess the effects of organic and inorganic copper on performance in growing pigs. A total of 100 pigs, average age 63 d and initial body weight 21.46${\pm}$1.13 kg, were assigned to five treatment groups. Dietary treatments included i) CON (basal diet, 0 ppm Cu), ii) T1 (basal diet with 67 ppm Cu as cupric sulfate, $CuSO_4$), iii) T2 (basal diet with 134 ppm Cu as $CuSO_4$), iv) T3 (basal diet with 67 ppm Cu as cupric methionate, CuMet) and v) T4 (basal diet with 134 ppm Cu as CuMet). Throughout the entire experimental period, ADG (average daily gain), ADFI (average daily feed intake) and G/F (gain: feed) ratios showed no significant differences. The dry matter digestibility was improved in the T1, T2, T3, and T4 treatments (p<0.05), as compared with CON. Nitrogen digestibility was improved in the T3 treatment group as compared with CON (p<0.05). As compared with the T1 treatment group, fecal pH values were improved in the CON, T3, and T4 treatment groups (p<0.05). Fecal Cu concentrations were significantly lower in the CON, T3, and T4 treatment groups than in T1 and T2 (p<0.05). The incidence of diarrhea was reduced when the pigs were fed on the T2, T3, and T4 diets as compared with CON. In conclusion, diets supplemented with 67 or 134 ppm Cu as CuMet may prove effective in improving nutrient digestibility and fecal pH value in growing pigs, and fecal Cu concentrations may be reduced by CuMet supplementation.
