개에서의 피부, 피부조직학, 임상병리학 및 갑상선 기능에 있어서 지방산 농도에 관한 규정식 중 다양한 단백질들의 제반 영향(6)
White Stephen D.,Rosychuk Rod A.W.,Scott Kathryn V.,Carey Daniel P.,Longardner Curtis,Schultheiss Patricia C.,Salman Mowafak 대한수의사회 1997 대한수의사회지 Vol.33 No.1
12마리의 개들을 12주동안 6종류의 규정식으로 각각 급여시켰다. 규정식들은 단지 단백질원 즉 닭고기, 새끼양의 고기, 물고기, 쇠고기 및 콩이란 것에서만 차이가 있었다. 개들은 CBC 즉, 혈청화학프로필, 요분석, TSH반응시험 및 피부생검을 통하여 평가하였다. 피부생검은 조직학적으로 하는 것과 피부지방산 농도의 측정을 통한 평가, 두가지 방법으로 평가하였다. 평가된 지방산들은 리롤레산, 감마-리롤렌산, 알파-리롤렌산, 아라키돈산, 아이코사테트라에노이산 및 아이코사펜타에노이산 등이었다. 개들은 주관적으로 생검채취부위에서 털의 재성장과 비늘(피부의 얇은 조각)의 존재유무로 평가하였다. 결과에서 보면 각종의 규정식을 급여시킨 개들 사이에서 CBS, 조직적 소견 또는 피부지방산 수치에서 차이가 나타나지 않았다. 쇠고기 규정식을 급여시킨 12마리중 3마리의 개에서 고콜레스테롤 혈증이 있었고, 콩 규정식을 급여시킨 12마리중 9마리의 개에서 알카리성 오줌과 돼지고기를 급여시킨 12마리중 4마리가 비늘이 주관적 증가가 있었고, 털의 재성장이 감소된 것으로 나타났다.

Purpose: Traditionally, three-dimensional conformal radiation therapy (3D-CRT) is used for neoadjuvant chemoradiation in locally advanced rectal cancer. Intensity-modulated radiation therapy (IMRT) was later developed for more conformal dose distribution, with the potential for reduced toxicity across many disease sites. We sought to use the National Cancer Database (NCDB) to examine trends and predictors for IMRT use in rectal cancer. Materials and Methods: We queried the NCDB from 2004 to 2015 for patients with rectal adenocarcinoma treated with neoadjuvant concurrent chemoradiation to standard doses followed by surgical resection. Odds ratios were used to determine predictors of IMRT use. Univariable and multivariable Cox regressions were used to determine potential predictors of overall survival (OS). Propensity matching was used to account for any indication bias. Results: Among 21,490 eligible patients, 3,131 were treated with IMRT. IMRT use increased from 1% in 2004 to 22% in 2014. Predictors for IMRT use included increased N stage, higher comorbidity score, more recent year, treatment at an academic facility, increased income, and higher educational level. On propensity-adjusted, multivariable analysis, male gender, increased distance to facility, higher comorbidity score, IMRT technique, government insurance, African-American race, and non-metro location were predictive of worse OS. Of note, the complete response rate at time of surgery was 28% with non-IMRT and 21% with IMRT. Conclusion: IMRT use has steadily increased in the treatment of rectal cancer, but still remains only a fraction of overall treatment technique, more often reserved for higher disease burden
