Biological sensors have been becoming more important to monitor the quality of the aquatic environment, especially the presence of hazardous compounds. This study was designed to develop a biomonitoring system based on the respiratory and movement responses of carp (Cyprinus carpio) to monitor water quality. Diazinon, phenol, cadmium, and LAS were selected as test chemicals and exposure concentrations was ranged from acute toxicity level to one 100th of the highest concentration. When exposed to the acute level concentration, the first response were detected within 3 hr for LAS, 0.5 hr for cadmium and phenol and 15 hr for diazinon in this system. In case of cadmium, the significant response was shown at the chronic level and this system, therefore, could detect not only the acute level of LAS, cadmium, and phenol within 3 hr but also the chronic level of cadmium within less than 4 hr after exposure. In conclusion, present study proved that this biological monitoring system using fish respiration and movement as a sensor could be one of the promising approach to detect and prevent a toxic pollutant release into the aquatic environment.

There have been many reports of cancer arising from gastric remnant after partial gastrectomy for benign disease, but few cases of cancer after partial gastrectomy for malignant disease, In recent years there has been an increase in the number of patients whose cancer was found in the gastric remnant after gastrectomy for malignant disease. Such cancers in the gastric remnant seem likely to increase due to the rise in numbers of operations for early gastric cancer. Diagnosis of gastric remnant cancer is difficult, and such lesions are often found at an advanced stage when symptoms appeared. After partial gastrectomy for gastric cancer, even in asymptomatic patients, we recommend periodic endoscopic examination including biopsy. The endoscopist should carefully inspect not only the site of anastomosis but also the other regions of stomach. Recently we experienced one case of early gastric cancer arising from gastric remnant 17 years after subtotal gastrectomy for advanced gastric cancer, therefore we report it with review of literatures.
