A 43-year-old woman with diabetic nephropathy underwent a Tc-99m MAG3 renal scintigraphy for the evaluation of renal function. Posterior images at 60 minutes demonstrated a migration of radiotracer activity beyond the lower pole of the left kidney, which might be incorrectly interpreted as urine leaks. However, the increased activities were moving along the bowel lumens over time. Another ring-like radioactivity was also seen in the suprasplenic region, and increased with time. These radioactivities were in the gastric fundus and gastrointestinal tract and caused by free Tc-99m pertechnetate.

In this study the Ayurvedic formulation Dasamularista was studied for its preliminary pharmacological properties using laboratory mice. Dasamularista showed a decrease in food intake and stool formation, while the water content of stool and water intake was higher and the volume of the urine was less. Dasamularista in a slight extent reduced the intestinal motility. This constipating effect was further supported by the significant anti-diarrhoeal property of the formulation in castor oil induced dairrhoea. The tested formulation markedly increased the latent period of diarrhoea and reduced the purging index value. Dasamularista did not alter the acetic acid induced abdominal writhing. Significant reduction on the onset of sleeping time and increased duration of sleep was observed in pentobarbital induced sleeping time test.

This study was performed to investigate the usefulness of the radiopaque material as a disintegration test of enteric coated capsules radiologically. The results obtained were as follows; 1. The times that the enteric coated capsules passed the pylorus(GI transition times) were the first 150 minute and the last 390 minutes. Therefore, the GI transition times largely differ from each animal and each enteric coated capsule. 2. The disintegration times of enteric coated capsules were similar in vitro test and in vitro test. 3. The disintegration test of enteric coated capsules using Barium sulfate, radiopaque material for the gastrointestinal track, was useful to check the time pass through the pylorus and the time enteric coated capsules were disintegration.

This study was carried to investigate the usefulness of the radiopaque material as the GI transition and disintegration test of enteric coated capsules radiologically. The obtained results were as follows; 1. The GI transition times that the enteric coated capsules pass through the pylorus were that the time of the first capsule was 210 minutes and the time of the last capsules was more than 300 minutes. Therefore, the GI transition times largely differ from each animal and each enteric coated capsule. 2. The disintegration times of enteric coated capsules were similar in vitro test and in vivo test. 3. The GI transition and disintegration test of enteric coated capsules using barium sulfate, radiopaque material for the gastrointestinal track, was useful to investigate the times that the capsules passed through the pylorus and disintegrated in intestinal track.

Objectives: The purpose of this study was to describe the effectiveness of Jeoreongchajeonja-tang as a treatment for patients with diarrhea-predominant irritable bowel syndrome (IBS-D). Methods: Two irritable bowel syndrome patients who had visited Semyung University Korean Medical Hospital were enrolled. The patients were diagnosed according to the Rome III criteria, and the treatment effect was assessed using the Gastrointestinal Symptom Rating Scale (GSRS) and the colon transit time. Results: After treatment with Jeoreongchajeonja-tang for 4 weeks, the GSRS score was improved and colon transit time was delayed. Conclusions: This study suggests that Jeoreongchajeonja-tang is effective for improving diarrhea-predominant irritable bowel syndrome. More extensive study is needed in the future.

Unlike wired endoscopy, capsule endoscopy requires additional time for a clinical specialist to review the operation and examine the lesions. To reduce the tedious review time and increase the accuracy of medical examinations, various approaches have been reported based on artificial intelligence for computer-aided diagnosis. Recently, deep learning-based approaches have been applied to many possible areas, showing greatly improved performance, especially for image-based recognition and classification. By reviewing recent deep learning-based approaches for clinical applications, we present the current status and future direction of artificial intelligence for capsule endoscopy.

It is important to choose the appropriate treatment option for patients with colorectal cancer (CRC), because it could affect the prognosis of patients. Chemotherapy is effective in prolonging survival and time to progression in patients with advanced CRC. Adjuvant chemotherapy have been reported to reduce the recurrence rate of colorectal cancer by 30% in patients with stage 3 or high risk of stage 2 CRC. Although palliative chemotherapy does not offer long-term benefits, as life expectancy remains below 12 months in most of those receiving treatment, recent developments in the treatment including target agents and immunotherapy have improved the median overall survival time in patients with metastatic CRC by up to 30 months. Chemotherapy for patients with CRC is classified into neoadjuvant, adjuvant, and palliative therapy according to the status of patients. In this review, I summarized the chemotherapy for patients with CRC, which applying in clinical practice.

수의 임상에서 캡슐 내시경(capsule endoscopy, CE)의 사용에 기본적인 기준과 유용성을 정립하기 위하여 정상 중형견($7{\sim}13\;kg$)에서 캡슐의 위 통과시간(gastric transit time, GTT), 작은창자 통과시간(small intestinal transit time, SITT), 완전통과율(complete transit time, CTT)을 측정하고 통과율을 분석하였다. 1군(capsule 투여), 2군(capsule+water 투여), 3군(metoclopramide+capsule 투여) 그리고 (metoclopramide+capsule+water 투여)의 총 4군으로 나누어 방사선 촬영을 통하여 평가를 실시했다. GTT는 평균 $45{\sim}20\;min$ (group 1), $117{\pm}35\;min$ (group 2), $150{\pm}40\;min$ (group 3), $154{\pm}65\;min$ (group 4)였으며 SITT는 평균 $75{\pm}20\;min$ (group 1), $195{\pm}55\;min$ (group 2), $75{\pm}15\;min$(group 3), $76{\pm}15\;min$ (group 4)로 나타났다. 완전통과율(complete passage rate)은 각각 20% (group 1), 40%, (group 2), 20% (group 3), 50% (group 4)로 나타났다. 실험결과 캡슐이 유문부를 통과하기만 하면 내시경 캡슐 배터리 수명인 8시간 이내로 위장관을 모두 통과하였으며 물을 위내로 투여한 후 volume의 증가에 의한 위 운동성의 증가는 캡슐의 유문부 통과에 도움이 되었다. 그러나 metoclopramide의 투여는 유문부의 통과와 SITT의 시간에 대한 유의적인 효과가 나타나지 않았다.

침(鍼) 치료효과(治療效果)에 영향을 주는 자극(刺戟) 시간(時間)과 자침(刺鍼) 깊이 및 시술(施術) 기간(期間)에 따른 효과차리(效果差異)를 관찰하기 위하여 족삼리(足三里)에 전침(電鍼)을 사용하여 위산분비를 촉진시키는 호르몬인 혈중 gastrin 농도의 변화를 관찰하여 다음과 같은 결과를 얻었다. 1. 자침 시간의 비교에서 10분, 30분 실험군에서는 대조군에 비하여 혈중 gastrin 농도를 유의하게 증가시켰으나, 60분 실험군에서는 변화를 관찰할 수 없었다. 2. 시술 기간의 비교에서 5일과 10일 실험군에서는 대조군에 비하여 혈중 gastrin 농도를 유의하게 증가시켰으나, 1일 실험군에서는 변화를 관찰할 수 없었다. 3. 자침 깊이의 비교에서 전체자극군과 피부자극군에서는 대조군에 비해 혈중 gastrin 농도를 유의하게 증가시켰으나, 심부자극군에서는 변화를 관찰할 수 없었다. 이상의 결과로 미루어 침 치료효과를 실질적으로 향상시키기 위해서는 영향을 줄 수 있는 다양한 인자들에 대한 실험적, 임상적 비교 연구가 진행되어 임상과 기초이론에 활용할 수 있는 자료가 구축되어야 할 것으로 사료된다.

The absorption profile of phenytoin Na emulsion were examined compared to that of phenytoin suspension after oral administration in the rat. The corn oil-in-water emulsion, particle size of $184{\pm}$57.8 nm, was prepared using a microfludizer, and phenytoin Na added by shaft homogenizer. The phenytoin emulsion or suspension, 100 mg/kg, were intubated intragastrically using oral dosing needle and blood samples were withdrawn via an indwelling cannula from the conscious rat. Plasma concentrations of phenytoin were measured with HPLC using phenacetin as an internal standard. The plasma concentration versus time data were fitted to a one compartment open model and the pharmacokinetic parameters were calculated using the computer program, Boomer. The phenytoin plasma concentrations from the emulsion at each observed time were about 1.5-2 times higher than those from the suspension, significantly at time of 5, 6 and 7 hr after administration. The absorption $(k_a)$ and elimination rate constant $(k_e)$ were not altered significantly, however the AUC increased from 65.6 to $106.7{\mu}ghr/ml$ after phenytoin suspension or emulsion oral administration, respectively. From an equilibrium dialysis study, the diffusion rate constant $(k_{IE})$ was considerably higher from the phenytoin Na emulsion $(0.0439 hr{-1})$ than phenytoin suspension $(0.0014 hr{-1})$.
