  • 한국산 칼납자루의 암컷은 산란시기가 되면 배지느러미 기부 부근에 돌출되어 신장되어 나타나는 배측융기가 형성된다. 이러한 배측융기는 직장(항문)부분과 내측산란관으로 구성되었다. 직장은 점막층, 점막하층, 근육층과 이들을 둘러싸는 다층의 표층으로 구성되어 있으며 특히 점막층에는 산성 점액다당류인 점액세포가 존재한다. 한편 내측산란관은 직장과 비슷한 구조를 가지고 있으나 점막층에는 점액세포가 존재하지 않는 특징을 보였다. 한편 외측산란관은 배측융기와 연결되지 않아 가늘고, 긴 관의 형태를 보이고 있으나 내측산란관과 달리 근육층이 존재하지 않아 점막층, 점막하층, 다층의 표피층으로 구성되어 있다. 이러한 결과로 보아 근육층을 가지는 내측산란관은 성숙란을 외측산란관으로 내보기 위해 연동운동과 관련있는 반면에 외측산란관은 근육층이 존재하지 않아 내측산란관으로부터 방출된 성숙란을 단지 이매패 속으로 전달하는 단순한 관의 역할을 하는 것으로 생각된다.

  • These studies were carried out to develop some easy-checking thermometers instead of taking temperature of ectum for the farmers to detect easily a diseased animal with fever. Thermometers such as pincher-type, hood-type, raser-type, stick-type, and wrap-type were devised for the experiments. The experimental animals were cattle, horse, swine, aprine, and canine. Temperature-taking parts of the body were ear, shoulder, axilla, gluteal part, and coccygeal part according o the devised thermometer. Rectal temperature was taken at the same time for the comparison of temperature between rectum nd the certain part. The difference of temperature between rectum and shoulder part using eraser-type thermometer for the domestic animals were $3.37^{\circ}C$ for cattle, $1.94^{\circ}C$ for horses, $2.04^{\circ}C$ for swine, $1.27^{\circ}C$ for caprine, $0.9^{\circ}C$ for canine. The difference of temperature between rectum and gluteal part using eraser-type thermometer for domestic animals were $3.46^{\circ}C$ for cattle, $1.98^{\circ}C$ for horses, $2.22^{\circ}C$ for swine, and $1.1^{\circ}C$ for canine. The difference of intra-individual temperature taken by eraser-type thermometer of shoulder and gluteal part were 0.3 and $0.8^{\circ}C$ for cattle, 0.7 and $1.1^{\circ}C$ for horses, 0.6 and $0.7^{\circ}C$ for swine, 0.9 and $1.1^{\circ}C$ for canine. The difference of temperature between rectum and shoulder part taken by hood-type thermometer for cattle was $3.93^{\circ}C$ and the difference of intra-individual temperature was $0.8^{\circ}C$. The difference of temperature between rectum and gluteal part taken by stick-type thermometer for cattle was $3.7^{\circ}C$ and the difference of intra-individual temperature was $0.8^{\circ}C$. The other types of thermometers than the above three were not proved to be reliable to detect temperature of domestic animals. It was concluded that hood-type, stick-type and eraser-type thermometers are recommendable devices of thermometer to detect easily the status of body temperature and that the eraser-type was proved to be a practical one of the thermometers used in this study.

  • 목적 : 자궁경부암 환자의 고선량률 근접치료 시 부작용을 줄이기 위해 가장 주의 깊게 선량을 고려해야 할 곳은 직장과 방광이다. 일반적으로 직장이나 방광에서의 선량값은 Planning장치의 계산값에만 의존하고 있는 상태이고, TLD를 이용한 직장 선량분석은 보고된 바 있으나 In vivo dosimetry(Diode detector)를 이용한 보고는 거의 없었다. 본 연구에서는 자궁경부암 환자치료 시 매번 diode detector를 직장 내에 삽입하여 직장 선량을 측정하고 측정된 값을 토대로 직장의 부작용을 줄이는데 기초 자료로 활용 하고자 하였다. 대상 및 방법 : 2003년 2월부터 2003년 6월까지 Ir-192 동위원소 고선량률 근접치료기로 치료받은 자궁경부암환자 6명(tandem and ovoid 4명, cylinder 1명, tandem and cylinder 1명)을 대상으로 총 28회 측정을 실시하였고 직장내 Diode detector를 매번 측정 시마다 anterior, lateral film을 동일한 지점에서 촬영 후, Planing을 실시하여 측정값과 비교해 보았다. 결과 : 4명의 tandem md ovoid에서 3명의 직장내 Diode detector측정값의 평균과 편차는 $274.1{\pm}13.4cGy$이고 1명의 tandem and ovoid에서 $126.1{\pm}7.2cGy$, cylinder에서 $99.7{\pm}7.1cGy$, tandem and cylinder에서 $77.7{\pm}11.5cGy$이었다. 결론 : 직장의 매 측정 시마다 Diode detector측정값은 직장의 상태에 따라 표준편차가 매우 크므로 단 한번의 치료계획 계산 값으로 직장의 부작용을 예측하는 것은 어렵다. 본 연구에서 얻어진 결과로 볼 때 가능하다면 TLD 또는 In vivo dosimetry 장비를 이용하여 치료 시마다 실측하여 직장의 부작용을 판단하는 것이 중요하며 직장의 부작용이 예상될 시 gauze packing 및 조사시간을 조절하거나 shielded된 기구를 사용하여 직장의 선량을 낮추도록 하는 것이 필요하다고 사료된다.

  • Rectal stricture occurred in 2 finishing pigs submitted for necropsy from Moguchon, the meat processing plant, chonbuk. Grossly, the wall of the rectum was harden and thickened by fibrous tissue. Anteriro to the stricture, the descending colon was dilated up to 30cm in diameter, filled with gas and pasty green fluidal feces. Histologically, the epithelia of rectal mucosa were necrotized. The mucosa and submucosa of rectum were infiltrated by macrophages, eosinophils and lymphocytes. This infiltration was the most extensive in the deeper layer of submucosa and intensive fibrosis was observed in deeper submucosa layer. This case is report for rectal stricture of finishing pig.

  • Endocrine cells were observed in the gastrointestinal tract of the squirrels by light microscopy using Grimelius and Masson-Hamperl silver impregnation, and in the stomach and duodenum by electron microscopy. Light microscopically, argyrophil cell decreased gradually in number in the pyloric region and ileum, stomach, duodenum and jejunum and rectum in the order listed. Argentaffin cells were moderately distributed in the stomach, pyloric region and duodenum, while absent in the jejunum, ileum and rectum. Five kinds of cell types, EC, ECL, D, $D_1$ and G cells were identified in the stomach and three kinds of cell types, S, $EC_1$ and $EC_2$ were also identified in the duodenum by electron microscopy. A cilium noted in the cytoplasm of $D_1$-type cell. The species differences in the distribution, size and structure of the secretory granules were discussed.

  • Thirty Patients with loco-regional recurrence following curative surgery for adenocarcinoma of the rectum were retrospectively evaluated to determine factors influencing survival and the efficacy of radiation therapy. In this review of 30 patients undergoing radiation therapy, more than 50 percent(17/30) had definite symptomatic and objective response. Ninety percent of patients(27/30) received significant palliation. Over all 2 year survival rate was $7.4\%$ and their median survival was 13.0 months. Grade of response and Sex were statistically related to survival.

  • This report describes a three-month-old Korean domestic kitten presented with dehydration and poor body condition. Physical examination revealed abdominal distension. Rectal diagnosis was unachievable due to the small rectum diameter. X-ray radiography and endoscopy confirmed presence of abdominal distension and indicated a stricture located 1.5 cm from the anus. A balloon was gently inserted into the rectum and inflated several times followed by triamcinolone injection. Four months later, same procedures were repeated. This report is the first to describe the use of balloon dilation of a rectal stricture followed by intralesional triamcinolone injection in a small cat with poor condition.
