Objectives: This case study reports the effectiveness of Korean medical treatment in a patient with cyclic vomiting syndrome. Methods: A 29-year-old female Korean patient with cyclic vomiting syndrome received acupuncture, electroacupuncture, herbal medicine, and moxibustion for 2 weeks in hospital. Changes in symptoms were evaluated using the Gastrointestinal Symptom Rating Scale (GSRS), Visual Analog Scale (VAS), Index for Nausea, Vomiting, and Retching (INVR), Nausea Severity Scale (NSS), Nepean Dyspepsia Index-Korean version (NDI-K), quality of life using the Functional Dyspepsia Related Quality of Life questionnaire (FD-QoL), and gastric motility using electrogastrography (EGG). Results: Post-treatment, the patient showed high satisfaction and improvement in symptoms of nausea and vomiting. The following changes were observed in scores: GSRS: 23 to 19; VAS of nausea: 88 to 95; VAS of dyspepsia: 95 to 12; INVR: 13 to 1; NSS: 17 to 5; NDI-K: 107 to 78; and FD-QoL 84 to 27. We also found positive results in Channel 3 of EGG parameters, implying the improvement of gastric motility disorder. Conclusion: Korean medical treatment can be a therapeutic option for cyclic vomiting syndrome.

Purpose: This study aimed to identify the levels of oxaliplatin-induced peripheral neuropathy (OXLIPN) and the quality of life (QOL) related to OXLIPN in patients with digestive system cancer. Methods: A total of 83 patients with chemotherapy-induced peripheral neuropathy (CIPN)-related symptoms participated in this study. Data were collected through self-reported questionnaire which were constructed to include general and clinical characteristics, EORTC QLQ-C30, Patient Neurotoxicity Questionnaire (PNQ), and EORTC QLQ-CIPN20. Results: The average scores of OXLIPN upper and lower extremity scale were 30.01 and 29.16, respectively. The average scores of PNQ sensory and motor scale were 2.11 and 1.70, respectively. The mean score of the QLQ-C30 global health status was 54.85, and the range of mean score of the functional and symptom subdomains was 34.85~73.29 and 17.67~53.54, respectively. The CIPN-related symptoms positively correlated with the global health status scale and all subdomains of functional scale, respectively and negatively correlated with fatigue, pain, dyspnea, insomnia, and financial problem subdomains of the symptom scale, respectively. Conclusion: Oncology nurses should pay attention and provide remedies for CIPN symptoms reported by their patients. Nursing interventions should be developed for patients with digestive system cancer to alleviate CIPN and enhance their QOL.

Development of a locomotive mechanism for the capsule type endoscopes will largely enhance the ability to diagnose disease of digestive organs. In connection with it, most of the researches have focused on an installable locomotive mechanism in the capsule. In this paper, it is introduced that the movement of a capsule type endoscope in digestive organ can be manipulated by magnetic force produced outside human body. Since the magnetic force is provided by permanent magnets, no additional power supply to the capsule is required. Using a robotic manipulator for locating the external magnet, the capsule motion control system can cover the whole human digestive organs. This study is particularly concentrated on dither motion effect to improve the mobility of capsule type endoscope. It was experimentally found out that the friction coefficient between the capsule and digestive organ can be remarkably reduced by superposing yawing or rolling dither motion on the translatory motion. In this paper, the experimental results obtained while the direction, amplitude and frequency of sinusoidal dither motion were changed are reported.

The main purpose of this study was to develop a novel, in situ gel system for sustained delivery of ranitidine hydrochloride. Ranitidine in situ gels at 0.2%, 0.5%, and 1.0% gellan gum concentration (w/v) were prepared, respectively, and characterized in terms of preparation, viscosity and in vitro release. The viscosity of the gellan gum formulations in solution increased with increasing concentrations of gellan gum. In vitro study showed that the release of ranitidine from these gels was characterized by an initial phase of high release (burst effect) and translated to the second phase of moderate release. Single photon emission computing tomography technique was used to evaluate the stomach residence time of gel containing $^{99m}Tc$ tracer. The animal experiment suggested in situ gel had feasibility of forming gels in stomach and sustained the ranitidine release from the gels over the period of at least 8 h. In conclusion, the in situ gel system is a promising approach for the oral delivery of ranitidine for the therapeutic effects improvement.

Diseases in the gastro-intestinal tract are on an increasing trend. In order to diagnose a patient, various signals of the digestive organ, such as temperature, pH, and pressure, can offer the helpful information. Among the above mentioned signals, we choose the pressure variation as a monitoring signal. The variation of a pressure signal of the gastro-intestinal tract can offer the information of a digestive trouble or some clues of the diseases. In this paper, a pressure monitoring system for the digestive organs of a living pig is presented. This is why a pig's gastro-intestinal tract is very similar as human's. This system concept is to transmit the measured biomedical signals from a transmitter in a living pig to a wireless receiver that is positioned out of body. The integrated solution includes the swallow type pressure capsule and the receiving set consisting of a receiver, decoder circuit. The merit of the proposed system is that the monitoring system can supply the precise and a durable characteristic to measure and to transmit a signal in the gastro-intestinal tract. We achieved the pressure tracings in digestive organs and verified the validity of system after several in-vivo tests using the pressure monitoring system. Through various experiments, we found each organ has its own characterized pressure fluctuation.

The heavy metal concentrations of seawater collected from the Onsan coastal zone in February and July 1996 and mussels(Mytilus edulis) in February 1997 were analysed. The concentrations of cadmium in seawater were in the range of 0.008-2.988 ${\mu}g/L$, while the ranges of copper and zinc concentrations were 0.08-2.55, and 0.21-35.12 ${\mu}g/L$, respectively. The metal concentrations decreased gradually with increasing distances from Daejeong stream, indicating that this stream was the major source of heavy metal input into the Onsan coastal zone. The concentrations of cadmium, copper and zinc in mussels were in the ranges of 1.40-25.09, 8.5-64.5, and 46.8-291.2 ${\mu}g/g$, respectively. The metal concentrations decreased gradually with increasing distances from Daejeong stream. Among organs of mussels, gill showed the highest concentrations of cadmium and the digestive gland showed the highest concentrations of copper and for zine the kidney showed the highest concentrations. The digestive gland and kidney revealed high proportion of cadmium in cytosolic fraction and the percentage of copper was high in the kidney and that of zine was high in the digestive gland. Metal-binding protein of mussels collected from the mouth of Daejeong stream was separated, using gel-filtration chromatography. In the kidney and gill of mussels, most of cadmium was associated with metal-binding protein. In contrast, most of the metal in the digestive gland and remaining tissues is bound to high molecular weight protein rather than metal-binding protein.

Cadmium (Cd) accumulation and elimination were assessed in the tissues of the clam R. philippinarum at four experimental concentrations (control, 10, 20, 100, and $200\;{\mu}g/L$) over an exposure period of 2 weeks and an elimination period of 1 week. Cd accumulated in the digestive gland, gill, and residual clam tissues, and accumulation increased with time of exposure and concentration (100 and $200\;{\mu}g/L$). After 2 weeks of Cd exposure, the order of Cd accumulation in tissues was gill > digestive gland > residual tissues. An inverse relationship was observed between concentration factor (CF) and exposure level, but the CF showed an increase with exposure time. During the depuration period, Cd concentrations in the digestive gland, gill, and residual tissues decreased immediately on the cessation of exposure, except in individuals at the $200\;{\mu}g/L$ concentration. The Cd elimination rate from tissues decreased in the order of digestive gland > gill > residual tissues during the depuration period.

Concentration and distribution of Fe, Zn, Cu, Cd, Mn, Pb, Ni among subcellular fractions (cellular membrane structures and cytosol) and Zn, Cu, Cd among cytoplasmic proteins in the kidney and digestive gland of mussel Modiolus modiolus living along a polymetallic concentration gradient were studied. It was found in the kidney of M. modiolus from contaminated sites that the Fe percent increased in the "membrane" fraction, whereas Zn, Pb, Ni and Mn percent increased in the cytosol compared to the kidney of the control mussel. Note kidney cytosol of M. modiolus from clean and contaminated sites sequestered major parts of Cu and Cd. In the digestive gland of M. modiolus from contaminated sites Fe, Zn, Cd, Mn, Ni percent increased in the "membrane" fraction, whereas Cu, Pb percent increased in the cytosol compared to digestive gland of control mussel. Gel-filtration chromatography shows kidney of M. modiolus contains increased metallothionein-like protein levels irrespective of ambient dissolved metal concentrations. It was shown that the metal detoxification system in the kidney and digestive gland of M. modiolus was efficient under extremely high ambient metal levels. However, under complex environmental contamination in the kidney of M. modiolus, the metal detoxification capacity of metallothionein-like proteins was damaged.

To determine effect of time after feeding on distribution of digesta in the gastro-intestinal tracts of sheep given orchardgrass hay once a day, a total of fifteen ewes (mean live weight $51{\pm}12kg$) were slaughtered at 2, 8, 16 and 24 hours after feeding. Contents in the reticulo-rumen, omasum, abomasums, small intestine, cecum, and colon and rectum were totally collected and weighed. Weights of digesta in the reticulo-rumen were about 6 kg which contributed about 75% of the total in the whole tracts. Digesta on dry-matter basis totaled about 1 kg. The dry-matter concentration of digesta in the whole digestive tract was about 107 h/kg of fresh digesta. Distribution of moisture in the digestive tract changed in parallel with that of fresh digesta. There was no significant correlation observed between time after feeding and weights of digesta in the gastro-intestinal tracts. While, feed intake significantly correlated with digesta in the reticulo-rumen, cecum and whole tracts (p<0.01). Thus, time after feeding was inferred to have no influence upon the content of digesta in the digestive tract, but feed intake influenced on the content of digesta in the digestive tract at a low level of feeding.
