  • Four isocaloric (68.71, 67.07, 66.68 and 66.25% TDN) and isonitrogenous (12.96, 13.36, 13.36 and 12.96% CP) diets without or with 20, 25 and 30% broiler litter were fed to 20 male kids for 90 days. Weight gain and feed efficiency were higher (p < 0.05) for kids offered control diets as compared to kids fed diets containing broiler litter. There was a significant (p < 0.05) decrease in the feed intake with increasing level of broiler litter in the diets. Digestibility for organic matter, crude protein and crude fibre were not affected (p > 0.05) by the inclusion of broiler litter in the diets, whereas inclusion of broiler litter depressed (p < 0.05) the digestibility of dry matter and ash. Nitrogen balance was positive for all diets, however, nitrogen retention decreased (p < 0.01) with the increased level of broiler litter. Blood Na, K, Ca, P and urea-N were within normal range.

  • The purpose of this study is to identify correlations among married nurses' parenting stress, job involvement and intent to stay, as well as to clarify factors that affect nurses' intent to stay. This is a descriptive study conducted based on evaluation of 174 married nurses from one university hospital and two general hospitals (200 beds or above) located in C region, all of who had at least one child <6 years of age. Data were collected from Aug 20 until Sep 15, 2016, after which data were analyzed by aT-test, ANOVA, Pearson's coefficient, and stepwise multiple regression. The mean score of parenting stress was $2.67{\pm}0.54$ out of 4, while that of job involvement was $3.11{\pm}0.58$ out of 5, and intent to stay was $3.56{\pm}0.79$ out of 5. Intent to stay was significantly negatively correlated with parenting stress(r=-0.186, p=0.014), while it was positively correlated with job involvement(r=0.345, p<0.001). Factors influencing intent to stay were education level(${\beta}=0.28$, p=0.042), job satisfaction(${\beta}=0.60$, p<0.001), weekend work(${\beta}=0.20$, p=0.042), job involvement(${\beta}=0.31$, p<0.001) and parenting stress(${\beta}=-0.22$, p=0.038). These factors explained 36.8% of intent to stay(F=21.18, p<0.001). Overall, the results indicate that intervention strategies may be necessary to increase intent to stay by reducing parenting stress and enhancing job involvement.

  • Soybean seed possesses about 15 allergenic proteins recognized by IgEs from soy-sensitive human. The allergenic impact of soybean proteins limit its extensive usage in a broad range of processed foods. Soybean protein P34 or Gly m Bd 30k of the cysteine protease family is one of the major allergen of the soybean seed. P34-null soybean, PI567476, was identified among soybean (Glycine max & Glycine soja Sieb. and Zucc) of approximately 16,226 accessions from USDA soybean germplasm screened. Also, for P34 gene (Williams 82; whole genome sequence cultivar) and P34 null gene (PI567476) comparative analysis of sequences listed in the NCBI database showed the presence of a SSLP (Simple Sequence Length Polymorphism) of 4 base pair. So, a SSLP marker was designed to reveal the polymorphism of the locus. In this study, a population of 339 $F_2$ recombinant inbred lines generated by cross between Taekwang (Glycine max) and PI567476 was used to select $F_{2:3}$ plant of a P34 null gene. The result separation rate Taekwang type, heterozygous type and PI567476 type were shown in 85: 187: 67 since single gene is concerned in as the separation rate of 1:2:1 in $X^2{_{0.05}}=5.99$, df=2. In future, selected plant will identify protein level, whether P34 null protein is equal to P34 null gene.

  • Purpose: Ga-67 scintigraphy has been used for the evaluation of tumors, especially lymphoma. Recently, Tl-201 and Tc-99m MIBI were also used to tumor imaging. Tl-201 and Tc-99m MIBI had better physiologic characteristics than Ga-67, so we studied 32 biopsy proven lymphoma patients (male 24, female 8, mean age 46 years) with Ga-67, Tl-201 or Tc-99m MIBI and compared the scan findings. Materials and Methods: Twenty-three of 32 patients were injected 74-111 MBq (2-3 mCi) of Tl-201, before chemotherapy and imaged with dual-headed SPECT (Prism 2000, Picker, USA) at 30 minutes after injection. Delayed images were obtained after 3 hr in 8 patients. Twenty seven of 32 patients were injected 740 MBq (20 mCi) of Tc-99m MIBI and imaged at 30 minutes after injection. 111-185 MBq (3-5 mCi) of Ga-67 was injected in 12 patients and imaged at 48 and 72 hours after injection. Twenty eight patients were diagnosed as non-Hodgkin's lymphoma and others were Hodgkin's lymphoma. Results: Twenty patients were positive on Tl-201 scan and 3 patients showed negative findings. One of these 3 patients, Tc-99m MIBI and Ga-67 scan were positive. Twenty two patients were positive on Tc-99m MIBI scan and 5 patients showed negative findings. One of these 5 patients, Tl-201 was positive and 2 were positive on Ga-67 scan. Ten of 12 patients showed positive findings on Ga-67 scan. The sensitivity of these agents were 83.3%, 87.0% and 81.5% for Ga-67, Tl-201 and Tc-99m MIBI, respectively. The sensitivity was highest in Tl-201 scan, but there were no significant differences among three tests. In this study, there was no significant difference of uptake ratios between early and delayed images of Tl-201. Conclusion: Scintigraphy with Tl-201 and Tc-99m MIBI in lymphoma patients have similar sensitivity with Ga-67.

  • Background: Tissue hypoxia is a characteristic of many human malignant neoplasms, and hypoxia inducible factor-1 (HIF-1) plays a pivotal role in essential adaptive response to hypoxia, and activates a signal pathway for the expression of the hypoxia-regulated genes, resulting in increased oxygen delivery or facilitating metabolic adaptation to hypoxia. Increased level of HIF-1 a has been reported in many human malignancies, but in esophageal squamous cell carcinoma, the influence of HIF-1 a on tumor biology, including neovascularization, is not still defined. Material and Method: The influence of HIF-1 a expression on angiogenic factors, correlation between the tumor proliferation and HIF-1 a expression, interaction of HIF-1 a expression and p53, and correlation between HIF-1 a expression and clinicopathological prognostic parameters were investigated, using immunohistochemical stains for HIF-1 a, VEGF, CD34, p53, and Ki-67 on 77 cases of resected esophageal squamous cell carcinoma. Result: HIF-1 a expression in cancer cells was found in 33 of 77 esophageal squamous cell carcinoma cases. The 33 cases (42.9%) showed positive stain for HIF-1 a. High HIF-1 a expression was significantly associated with several pathological parameters, such as histologic grade (p=0.032), pathological TMN stage (p=0.002), the depth of tumor invasion (p=0.022), regional lymph node metastasis (p=0.002), distant metastasis (p=0.049), and lymphatic invasion (p=0.004). High HIF-1 a expression had significant VEGF immunoreactivity (p=0.008) and Ki-67 labeling index (p<0.001), but was not correlated with microvascular density within tumors (p=0.088). The high HIF-1 a expression was correlated with aberrant p53 accumulation with a marginal significance (p=0.056). The overall 5-year survival rate was 34.9%. The survival rate of patients with a high HIF-1 a expression was worse than that of patients with low-expression tumors (log-rank test, p=0.0001). High HIF-1 a expression was independent unfavorable factors although statistical significance is marginal in multivariate analysis. Conclusion: It is suggested that (1) high HIF-1 a expression in esophageal squamous cell carcinoma is associated with tumor hypoxia, or with genetic alteration in early carcinogenesis and progressive stages, (2) high HIF-1 a expression may be associated with intratumoral neovascularization through HIF-VEGF pathway, and (3) high HIF-1 a expression is associated with poor prognosis in patients with esophageal squamous cell carcinoma and may playa role as biomarker for regional lymph node metastasis.
