  • It is well known that the essential pathology in traumatic anterior dislocation of the shoulder is the avulsion of the glenohumeral ligament complex from the glenoid. However, there are reports that the avulsion can occurs from the humeral attachments. We have experienced the 42 year-old male patient who had a traumatic lateral avulsion of the subscapularis and glenohumeral capsule from the humerus and reported the results of treatment.

  • Hookworm infections are rare causes of acute gastrointestinal bleeding. We report a middle aged man with primary nephrotic syndrome and pulmonary embolism. During the treatment with steroids and anticoagulants, the patient presented acute massive hemorrhage of the gastrointestinal tract. The results of gastroscopy showed red worms in the duodenum. Colonoscopy and CT angiogram of abdomen were unremarkable. Capsule endoscopy revealed fresh blood and multiple hookworms in the jejunum and ileum. Hookworms caused the acute intestinal bleeding. The patient responded well to albendazole. Hematochezia was markedly ameliorated after eliminating the parasites. Hence, hookworm infection should be considered in the differential diagnosis of a patient with obscure gastrointestinal bleeding. Capsule endoscopy may offer a better means of diagnosis for intestinal hookworm infections.

  • Wireless capsule endoscopy (WCE) was one of the most influential bio-medical electronic technologies to be developed at the beginning of the century. In comparison to traditional endoscopic diagnosis, this application is characterized as non-invasive and low-risk, thereby providing surgeons with a new alternative for inspecting the entire gastrointestinal (GI) track in a much more user friendly way. Apart from regular hardware upgrades, the frontier of WCE research basically lies in the miniaturization of the capsule and in active locomotion. In order to overcome the intrinsic drawback of current commercialized WCE products, which is that locomotion is generally a function of natural peristalsis, active locomotion is proposed as a series of strategies used to effectively navigate the device into different organs and conduct therapeutic functions within targeted human tissues. Reviews of several novel designs with respect to this aspect of research will be discussed in this article.

  • In order to accomplish a wireless communication of capsule endoscopy, an environment study in the human body and receiving antenna design have been performed. The proposed antenna is the loop antenna designed to minimize the propagation loss in multi-loss layer such as the human body and utilize the magnetic field. Considering the propagation loss in the human body, the frequency range is from 400 MHz to 500 MHz. Acorrrding to the FCC regulations, the permittivity and conductivity for each human tissue were extracted. We set up an equivalent model and make an aqueous solution which is replaced with the human body. Due to movement of capsule in the human body which propagation loss is extremly severe, an array antenna is required. Irrespective of the location of transmission antenna transmitting a signal of 1 mW, we confirme what it is possible for the enough signal detection as the average signal level of array antenna is -60 dBm.

  • Omeprazole is usually administered as encapsulated enteric-coated granules and enteric-coated tablets because of its acid-labile nature. For children and patients who can not swallow, it can be mixed with water or other liquid after a capsule is opened or a tablet is crushed. This study was performed to compare omeprazole liquid formulations of tablet and capsule Omeprazole 20 mg capsule containing enteric coated granules was opened and 20 mg entric-coated tablet was ground to be mixed with sodium bicarbonate solution, orange juice or water. Each liquid formulation was poured into dissolution tester, mixed with first solution (artificial gastric juice; pH 1.2) for two hours, then with second solution (artifical enteric juice; pH 6.8) for thirty minutes. pH was measured periodically for two and half hours. Samples were drawn periodically, mixed with lansoprazole as an internal standard, and injected to HPLC. As results, pH of sodium bicarbonate solution of omeprazole was significantly higher than that of orange juice or water in first solution (6.2-7.4 vs. 1.2, p<0.005). At 150 min, concentrations of omeprazole in three diluents with granules and in sodium bicarbonate solution of tablet powder sustained significantly higher than in other solution of tablet powder (p<0.001). In conclusion, enteric-coated granules from capsule with three diluents and powder from tablet in sodium bicarbonate solution was stable during dissolution test, which would be appropriate and recommended for patient who can not swallow solid preparations.

  • The purpose of the present study was to evaluate the bioequivalence of two nizatidine capsules, Axid (Lilly Korea Pharm. Co., Ltd.) and Nex (Bi-nex Pharm. Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). The nizatidine release from the two nizatidine capsules in vitro was tested using KP Apparatus method with various dissolution media (pH 1.2, 4.0, 6.8 buffer solutions and water). The dissolution prefers of two nizatidine capsules were very similar at all dissolution media. Twenty four normal male volunteers were divided into two groups with a randomized 22 crossover study. After two capsules (300 mg nizatidine) were orally administrated, blood was taken and the concentrations of nizatidine in serum were determined using HPLC with UV detector. The pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were determined. The result showed that the differences in $AUC_t$, $C_{max}$ and $T_{max}$ between two nizatidine capsules based on the Axid were -6.16%, -8.26% and -1.82%, respectively. There were no sequence effects between two capsules in these parameter. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(125)(e.g., $log(0.91){\sim}log(0.97)$ and $log(0.85) {\sim}log(0.99)$ for $AUC_t$ and $C_{max}$ respectively), indicting that Nex capsule is bioequivalent to Axid capsule.

  • Population density of the spiders (Micryphantidae and Lycosidae) in the two Paddy field at Suweon and Iri was studied following single root-zone application of carbofurans encapsulea and liquid-formulated and two to four paddy water applications of carbofuran to rice plants. In two field tests, the spider populations were reduced In all insecticide treatments. Among them, the reduction was greater in the capsule placement of carbofuran than in the liquid injection and broadcast of carbofuran. Their reduction was also enlarged with the increase of application rate of insecticide. The significant reduction of spider population in root-tone appliration of carbofuran was considered due to the food-chain toxicity on the spider-hopper system.

  • This paper presented a location and attitude estimation scheme of a capsule endoscope based on ultrasonic ranging. The scheme comprised eight on-capsule ultrasonic sensors to alleviate measurement errors due to irregularities in human body ultrasonic characteristics. It calculated the coordinate values and angles in a Cartesian coordinate system. The Matlab simulation reflecting random errors yielded the average deviations of 0.8mm in the location and $0.2^{\circ}$ in the attitude angle. These values are far smaller than normal intestine movement ranges inside human body, and will contribute accurate diagnosis of intestine.
