Canola박과 종자의 급여가 산란계의 혈장과 계란의 thiocyanate 이온함량에 미치는 영향

백인기,Robblee, A R 한국축산학회 1984 한국축산학회지 Vol.26 No.6

An experiment was conducted to determine the influence of feeding canola meal (CM) and canola seed (CS) to laying birds on the level of thiocyanate ion in blood plasma and egg. Blood and egg samples were obtained from Single Comb White Leghorn hens, 50 weeks of age, which had been placed on 16 different CM and CS diets. Concentration of thiocyanate ion in samples was determined with a gas chromatography equipped with an electron capture detector. The levels of thiocyanate ion in blood plasma of birds fed 10 to 20% of CM or 10 to 15% of CS were 4 to 5 times higher than those of soybean meal (SBM) controls. The levels of thiocyanate ion in egg serum of birds fed 10 to 20% of CM or 5 to 15% of CS were 1.5 to 2.5 times higher than those of SBM controls. The level of thiocyanate ion in blood plasma and those in egg serum were highly correlated (r = .87, P $lt; .01). The influence of CS on the level of thiocyanate was much greater than CM if comparison is made on oil-free basis. The level of energy or source of energy may influence the level of thiocyanate ion in egg serum of birds fed CS diets.

백인기,한인규,김춘수 ( In K . Paik,In K . Han,Chun S . Kim ) 한국축산학회 1975 한국축산학회지 Vol.17 No.4

An experiment was conducted to study the feeding value of extracted 44% soybean oil meal (SBM) produced by Dong Bang Oil Co. and also to determine the optimum using level of this meal. Three hundred broiler chickens were used for 8 weeks feeding trial and successive metabolic trial. Results obtained are as follows; 1. Body weight gain and feed intake increased significantly (P$lt;0.01) as the level of SBM increased in feed. However, no significant differences were observed in feed efficiency among 5%, 10%, 15% and 20% SBM groups. Only 0% SBM group showed significantly (P$lt;0.01) poor feed efficiency compared with other groups. 2. Protein utilizability of finisher diet increased as the level of SBM increased, but the differences were not statistically significant. On the other hand, utilizability of crude fat and total carbohydrate of 15% and 20% SBW groups were significantly (P$lt;0.05) lower than the other groups. 3. As the result of urease activity test was negative, SBM used was considered to be fully heat-treated. 4. General composition and amino acids content of local SBM was very similar to that of standard SBM of NAS. 5. Unit production cost for broiler meat decreased as the using level of SBM increased in broiler diet.

白仁基,洪錫宰,李東久 慶北大學校 醫科大學 1981 慶北醫大誌 Vol.22 No.1

1969年 1月부터 1978年 12月까지 滿 10年間 慶北大學敎 醫料大學 病理學敎室 및 大邱東山基督病院 病理科에서 組織學的으로 診斷된 滿 15歲 以下의 幼小兒腫瘍 491例를 對象으로 統計的으로 比較檢索한 結果를 要約하면 다음과 같다. 總 491例中 良性腫瘍이 305例(62.1%), 惡性은 186例(37.9%)였으며 惡性의 62.4%가 男子에서 發生하였다. 良性腫瘍은 主로 6歲 以上에서 觀察되었으나, 惡性에서는 약 半數가 5歲 以下에 分布하고 있었으며 惡性腫瘍의 13例(7.0%)는 1歲 미만의 영아에서 나타났다. 良性腫瘍에서 흔한 型은 毛細血管腫, 水滑液囊腫(cystic hygroma), 扁平上皮乳頭腫 順이었으며 惡性은 鋼膜芽細胞腫, 惡性淋巴腫 그리고 胎生癌의 順으로 頻發하였다. 小兒에서 稀有한 堅細胞癌, 甲狀腺乳頭狀癌, 耳下腺細胞癌을 各各 1例씩 觀察한 것은 特記할만한 것으로서 이들 腫瘍의 發生機轉을 說明하는데 參考되어야 할 것으로 생각된다. A statistical study was carried out on 491 cases of infants and children with tumors, diagnosed by surgical biopsy at department of pathology, Kyungpook, National University, School of Medicine and pathologic department of Daegu Presbyterian Medical Center during the period of 10 wears, from January 1969 through December 1978. The results were as follows; Cut of 491 cases, 305 (62.1%) were benign and 186 (37.8%) were malignant tumors. Male were more affected the female (62.4%) of malignant tumor, showing male to female ratio 1.7:1. Most of the benign tumors were diagnosed above 6 years of age. In malignant tumors, 45% occured below 5 years of age and 7% were under 1 year of age. In benign tumors, capillary hemangioma was in highest frequency and cystic hygroma, squamous papilloma were in next order. Among malignant tumors, retinoblastoma, malignant lymphoma and embryonic carcinoma were in order of frequency. Author observed 1 case in each of renal cell carcinoma, papillary carcinoma of thyroid gland and acinic cell carcinoma of salivary gland which could be a good reference to suggest the pathogenesis of these tumors.

Eschrichia coli O157의 효과적인 세균학적 진단법

백인기 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.1

■ Objectives Bacteriological isolation of Shiga toxin-producing Escherichia coli (STEC) from patient stool was not easy to perform in Korea. So polymerase chain reaction (PCR) for Shiga toxin has been used for diagnosis of STEC infection including Escherichia coli 0157 (0157) instead of culture, but bacteriological isolation must be followed for final diagnosis. Our study was aimed to introduce an effective, simple and sensitive method to isolate 0157 from patient stool. ■ Methods and Materials Standard strain of 0157 (SE97029) was cultured on Sorbitol-MacConkey (SMAC) agar and diluted in normal saline and mixed to stool of normal adult to make final concentration of 101-105 Colony Forming Unit (CFU) /ml of stool. Each concentration of sample was cultured in trypticase soy broth for 6 hours at 42℃ for enrichment and treated with acid (1/8N HCI) to suppress normal flora. After acid treatment it was streaked on Cefiximetellurite-sorbitol MacConkey (CT-SMAC) agar and cultured for 18 hours at 37℃. Various Concentration of cefixime were tested to know the most adequate concentration to suppress other enteric bacilli. Count of white and pink colonies on CT-SMAC agar was performed and serological test for 0 and H antigen of 0157 from white colonies which were suspected as 0157 was performed. ■ Results The most adequate cefixime concentration to suppress enteric bacilli other than 0157 were 0.1㎎/L in CT-SMAC agar. Also we could detect up to 103 CFU of 0157/g of stool by this method. ■ Conclusions This bacteriological isolation method would be an effective, simple and sensitive method for isolation of 0157 from patient stool.

사료수급정책의 개선과 생산비 절감방안

백인기 대한양계협회 1987 월간 양계 Vol.19 No.11

사료의 생산비를 절감하여 국제경쟁력을 높이고 결과적으로 축산물의 국제경쟁력을 높이는 것이 모든 정책 결정에 우선적으로 고려되어야 한다. 이를 위하여 행정 및 제도적으로는 사료용원료수입품목의 자유화, 곡류의 수입쿼터제 철폐, 국산곡류의 사료화지양, 사료원료 및 사료에 대한 세제 개선, 사료관리법개선 등의 조치가 취해져야 될 것인데 이러한 문제점들이 개선된다면 20-30$\%$의 사료의 가격경쟁력이 향상되리라고 기대된다. 사료공장의 입장에서 고려해야 할 과제들은 기술의 개선, Computer의 적극응용, 생산시설의 자동화, 생산품의 전문화, 유통질서의 확립 등을 들 수 있는데 이러한 과제들을 발전적으로 해결하므로써 생산비의 절감을 통한 국제경쟁력을 더욱 제고시킬 수 있을 것이다.

서울백병원 혈액은행 현황

백인기 인제대학교 1987 仁濟醫學 Vol.8 No.4

서울백병원 혈액은행의 최근 2∼3년 동안의 헌혈, 성분 제재 사용 현황, 전혈 사용 현황, 질환별 수혈 현황 및 1인 평균 수혈량 등을 통계 처리하여 혈액 사용의 현황을 제시하고자 하였다. The blood bank of Seoul Paik Hospital has the longest history as a blood bank of private hospital in Koera. We have served for Clinician during last 33 years. Total transfusion amount has increased slowly since the foundation of blood bank, but we have some problems still to solve in future steps. Author summarized the recent status about some fields of transfusion with recent 2 to 3 years data to compare with the status in other institutions in Korea. Blood component transfusion and blood donation have been remarkable increased during recent 2 to 3 years, especially since last autumn (1986). The reason might be activated cardiovascular surgery & active liver surgery since last autumn. Some data about transfusion were briefly summarized as follows : 1.The number of blood donation increased 2.7 times during 1987 compared with the number in 1985. 2.The ratio of blood component therapy increased 2.4 times during 1987 compared with the ratio in 1985. 3.Total transfusion amount (the number of whole blood used plus the number of blood components used) increased 2.4 times during 1987 compared with the amount in 1985. 4.Lots of transfusion was done in cardiovascular surgery compared with the one in other disease. 5.Average transfusion amount per 1 patient was 5.9 units. 6.The recipient of 1 unit transfusion still occupied 17.8% among the total recipients of transfusion. 7.Effective platelet transfusion is impossible without using apheresis. 8.Emergency fresh whole blood transfusion without any laboratory tests could make problems if we look forward AIDS.

효소 면역 측정법에 의한 혈중 T₃ 및 T₄ 농도의 측정

백인기 인제대학교 1987 仁濟醫學 Vol.8 No.2

효소면역 측정법에 의하여 갑상선 호르몬인 T3와 T4의 혈중농도를 측정, 이를 전통적 방법인 방사면역 측정법의 결과와 비교. 상관 관계를 고찰 하였으며 또한 각각의 장단점 비교 및 원가 계산을 시도하였다. Serum T3 &T4 are assayed by Enzyme Immunoassay in 42 samples (T3) & 30 samples(T4) and data are compared with Radio immunoassay results. Also I tried to investigate advantages & disadvantages by each method & investigate costs by each method. Correlation coefficient were 0.96 and 0.90 in T3 &T4 respectively & both results showed good correlationship. In assay procedure, it took 2 hour longer in EIA & Cost was more expensive in EIA compared C￣ RIA. Se I suggest insurance fee should be elevated to match for original costs in EIA.
