  • To determine relationships of biochemical parameters involved in Ca metabolism with eggshell quality, serum Ca level, duodenal and uterine calcium binding protein (CaBP) and uterine carbonic anhydrase (CA) activities were measured using 102-week old hens. Three groups of chickens were selected, those showing high quality (HQ) and low quality (LQ) eggshells and non-laying activity (NE). NE hens exhibited significantly (p < 0.05) lower serum Ca levels than laying hens. HQ and LQ hens were not different in the Ca level, indicating that serum Ca level was not good indicator of hen's ability to produce different quality eggshells. Duodenal CaBPs was highest in HQ and lowest in NE (p < 0.10). Uterine CaBPs of LQ and NE were not different and lower significantly (p<0.10) than that of HQ, suggesting that CaBP played an important role in determining eggshell quality. Uterine CA activities of the three groups were significantly different (p < 0.01) ; highest in HQ and lowest in NE, suggesting intimate relationship between CA and Eggshell quality.

  • A 33 year old male patient was admitted with 20 years history of recurrent hemoptysis. On clinical examination, mild left chest discomfortness and foul odored sputum with occasional rusty hemoptysis were principal complaints noted. Chest X-ray film revealed moderately advanced active tuberculosis lesion on both upper lung fields, and hen-egg sized mass surrounded with linear crescent of air shadow in a cavity on his left upper lung field. On left thoracotomy, dense pleural adhesions on left apicoposterior segmental surface with multiple lymphnode enlargements were noted, and the soft encapsulated mass of $5{\times}5{\times}8cm$ was localized in the apicoposterior segment of the left upper lobe. Apicoposterior segment with anterior segment of the left upper lobe was resected. Cavity was opened to find a rusty grayish colored, fragile mass, which was confirmed as "fungus ball" of aspergillosis by histological section slide with Gomori staining. The authors report one case of pulmonary aspergilloma superinfected with previous long standing pulmonary tbc.

  • This experiment was conducted to investigate the dietary effect of turmeric powder (TP) on laying performances, egg qualities and its transfer to eggs. A total of two hundred, 60-wk-old, Lohmann Brown layers were divided into 4 groups, placed in to 5 replicates per group (10 layers each) and fed each one of four diets containing 0 % TP(control), 0.1 % TP, 0.25 % TP, or 0.5 % TP for 7 wks, respectively. Egg production and egg mass in groups fed diets containing TP were higher than that of control(p<0.05). No differences in feed intakes, egg and eggshell qualities were observed among the treatments, but egg yolk color was increased significantly as TP was in increased in the diet(p<0.05). In groups fed diets containing TP, Haugh unit after 14 day of storage was significantly higher than that of control(p<0.05). The curcumin content of egg yolk in groups fed diet containing 0.50% TP was significantly higher than those of other groups (p<0.05). The content of egg yolk cholesterol was not influenced by dietary TP.

  • A 51 year old man was admitted to the Thoracic and Cardiovascular Department of Kyungpook University Hospital on April 7, 1976, with chief complaints of orthopnea and the chest pain for about 3 months. Physical examination showed narrow pulse pressure, puffy face, engorged neck veins at sitting position, distant heart sound, enlarged liver and edematous upper extremities. The chest roentgenogram demonstrated markedly enlarged cardiac silhouette. Low voltage and the low to diphagic T`s were noted on the electrocardiogram. Paroxysmal ventricular tachycardia was developed intermittently and was subsided spontaneously. Repeated pericardiocentesis were performed each of which yielded from 100 to 300ml. but intractable cardiac failure was progressed. The bacteriology and cytology of the pericardial fluid were not revealed any specific findings. The pericardiectomy was performed to release the intractable cardiac tamponade. Pericardium was found to be thickened and cardiac constriction was noted. The thickened pericardium was easily removed. A large hen`s egg sized dark blue tumor mass occupied the anterior wall of the right atrium and two thumb tip sized pearl gray tumors were placed at the just below portion of the main pulmonary artery. The biopsy report revealed primary fibrosarcoma of the heart. The patient was improved from the symptoms of the cardiac failure during the postoperative course.

  • The objective of this study was to get a comprehensive understanding of how genes in chicken shell gland modulate eggshell strength at the early stage of active calcification. Four 32-week old of purebred Xianju hens with consistent high or low shell breakage strength were grouped into two pairs. Using Affymetrix Chicken Array, a whole-transcriptome analysis was performed on hen's shell gland at 9 h post oviposition. Gene ontology enrichment analysis for differentially expressed (DE) transcripts was performed using the web-based GOEAST, and the validation of DE-transcripts was tested by qRT-PCR. 1,195 DE-transcripts, corresponding to 941 unique genes were identified in hens with strong eggshell compared to weak shell hens. According to gene ontology annotations, there are 77 DE-transcripts encoding ion transporters and secreted extracellular matrix proteins, and at least 26 DE-transcripts related to carbohydrate metabolism or post-translation glycosylation modification; furthermore, there are 88 signaling DE-transcripts. GO term enrichment analysis suggests that some DE-transcripts mediate reproductive hormones or neurotransmitters to affect eggshell quality through a complex suite of biophysical processes. These results reveal some candidate genes involved with eggshell strength at the early stage of active calcification which may facilitate our understanding of regulating mechanisms of eggshell quality.

  • Since the consumption of spent laying hens as roasted skewered meat increases, the effects of various carotenoids on pigmentation and antioxidant activity were tested with 62-wk-old 250 ISA brown laying hens to improve the quality of chicken meat. In a 6-wk feeding trial, 4 carotenoids with different polarity (${\beta}$-8-apo-carotenoic acid ethyl ester (ACAEE)>astaxanthin>canthaxanthin>${\beta}$-carotene) at 100 mg carotenoid/kg feed were used. The more polar the carotenoids, the higher were the levels in blood. After 5-wk adaptation, the concentrations of astaxanthin, canthaxanthin, and ACAEE in blood were -4 ${\mu}g/ml$. Canthaxanthin decreased significantly (p<0.05) the level of total blood cholesterol. Decreases in blood triglyceride by all carotenoids used were significant. ACAEE and astaxanthin tended to increase skin yellowness of thigh, breast, and wing proportionally to feeding period. In the case of polar carotenoids (ACAEE and astaxanthin), the longer the period of feeding, the higher the accumulation in skin was observed. Only astaxanthin was effective against the production of lipid peroxides in skin. Conclusively, out of the commercially available carotenoids we tested, astaxanthin is recommended for pigmentation of skin and inhibition of lipid oxidation.

  • 본 연구의 목적은 고온스트레스하에서 한방부산물의 첨가가 산란계의 생산성 및 난각특성에 미치는 영향을 조사하고자 실시하였다. 사양시험은 41주령 ISA brown 갈색계 144수를 공시하였으며, 처리구로는 옥수수-대두박 위주의 사료(Con; 기초사료), 기초사료에 한방부산물을 1.0% 첨가한 구(KMHR1.0; 기초사료+1.0% 한방부산물), 기초사료에 한방부산물을 2.0% 첨가한 구(KMHR2.0; 기초사료+2.0% 한방부산물)로 3개 처리로 구성되었다. 총 28일간의 사양시험기간 동안, 산란율에 있어 KMHR1.0 처리구가 다른 처리구와 비교하여 유의적으로 높게 평가되었다. (quadratic effect, p<0.01). 산란계 사료내 한방부산물을 첨가할 경우 난중 및 난각강도에는 영향을 미치지 못하는 것으로 평가되었다 (P>0.05). 난각두께는 둔단부, 예단부 그리고 중앙부에서 한방부산물 첨가구가 감소하는 경향을 보였으나 처리구간에 통계적으로 유의적인 차이는 보이지 않았다 (P>0.05). 난황색은 대조구와 비교하여 한방부산물의 첨가 수준이 증가함에 따라 높아지는 경향을 보였으나 통계적으로 유의적인 차이는 보이지 않았다 (P>0.05). 또한, 난황계수에 있어서도 대조구와 처리구간에 유의적인 차이를 보이지 않았다 (P>0.05). 혈청내 총 콜레스테롤, 중성지질, HDL-콜레스테롤과 LDL+VLDL-콜레스테롤 함량에 있어서는 대조구와 비교하여 한방부산물의 첨가 수준이 증가함에 높아지는 경 향을 보였으나 유의적인 차이는 보이지 않았다(P>0.05). 결론적으로, 고온 스트레스에 노출된 산란계에 있어 1.0% 수준의 한방부산물 첨가는 산란율을 증가시키는 것으로 사료된다.

  • 닭의 산란기를 I기(25-40 주령), II기(41-55주령), III기(56-69주령)의 3기로 구분하고 각 산란기에서의 에너지대사를 측정하여 얻은 결과는 다음과 같다. 1. 산란계의 절식시 열생산량(FHP)은 대사체중당 산란 I기 81.5Kcal, IIrl 76.1Kcal, IIIrl 97.5Kcal였다. 즉 FHP는 산란기에 의하여 변화하고 특히 III기의 FHP가 높게 나타났다. 이 현상은 III기에 공시계의 우모가 손상 또는 탈락하여 열손실을 크게 한 때문으로 생각된다. 2. 호흡시험에 있어서 사료 ME섭취량과 에너지 축적량(ER)과의 회귀식에서 구한 유지를 위한 ME 요구량(MEm)은 산란I, II, III기에 있어서 각각 대사체중당 123Kcal, 111Kcal, 131Kcal 였으며, 전기간 평균 119Kcal였다. 또 생산을 위한 ME의 정미이용효율(NAME)을 산란I기 76%, II기 79%, III기 74%, 전 기간 평균에선 79%였다. 즉 산란 III기는 I기 또는 II기에 비하하여 MEm가 높고 NAME가 낮은 성적을 보이고 있다.

  • Coptis japonica Makino (황련, 48.5%), Lonicera japonica Thunb (금은화, 48.5%), Morus alba L. (상엽, 3%)를 혼합한 복합 한약재의 급여가 생산된 계란의 냉장 저장 중 일반 성분 및 물리적 특성에 미치는 영향을 조사하였다. 28주령의 Lohmann Brown 108수를 3가지 처리(복합 한약재 0, 0.3 및 1%), 6반복으로 완전 임의 배치한 후 6주간 급여하고 생산된 계란을 수거하여 $4^{\circ}C$ 냉장 저장하면서 일반 성분, 색도 및 조직감 등을 관찰하였다. 복합 한약재를 급여하여 생산된 계란은 수분, 단백질, 지방 및 무기물의 함량 차이가 없었으며 삶은 계란에서 3일차 적색도($a^*$-value) 및 황색도($b^*$-value)를 제외하고는 처리간 색도의 차이가 없었다. 그러나 저장 기간동안 처리구와 상관없이 적색도와 황색도가 증가하였다. 전체적인 조직감 측정에서도 복합 한약재 급여 처리는 14일차 탄성(springness)을 제외하고는 차이가 나타나지 않았다. 다만 계란의 저장기간에 따른 조직감의 차이는 보여 탄성과 검성(gumminess)는 저장기간이 늘어나면서 감소하는 것으로 나타났다. 결과적으로 복합 한약재의 급여는 생산된 계란의 일반 성분이나 색도, 조직감 특성에서 대조구와 큰 차이가 없는 것으로 판단되며, 이는 합성 항생제를 대체를 위한 복합 한약재의 첨가를 산업적으로 적용할 때 계란의 물리화학적 품질에 큰 영향이 없을 것으로 사료된다.
