  • Five cases of esophageal cancer developed at the site of esophageal lye stricture were reported. Duration of lye stricture was between 13 and 40years, and all 5 cases had taken normal diet without appreciable troubles after recovery from the acute stage of burn till the suspected onset of esophageal malignaney. Outstanding symptoms of this grave condition were rather acute progressive dysphagia and frequent episodes of esophageal foreign bodies, Diagnosis could be confirmed easily by endoscopic biopsy in suspected eases, and all were epidermoid carcinoma histopathologically. Curative resection of this condition was made in neither of the cases, and their prognoses were more grave than other esophageal malignancies in our experience. The development of esophageal carcinoma at the site of corrosive esophagitis with resulting benign stricture has now been suspected as a cause and effect relationship between these two conditions, and Kiviranta: stated that the incidence of esophageal cancer in patients with lye stricture of longer duration is a thousand times higher than normal population. During last one decade the authors experienced 5 cases of esophageal carcinoma developed at the site of lye stricture of the esophagus among about 350 cases of lye burned esophagus at the Department of Thoracic & Cardiovascular Surgery, the National Medical Center in Seoul, Korea. In Korea they still use lye as a detergent in rural area, and there are still many persons ingesting lye for suicidal attempt or on accident. Lye stricture of the esophagus is, therefore, the most common esophageal disease needing surgical procedures, and the authors believe that there will be much more eases of lye stricture complicated by esophageal eareinoma repoted in near future in this Country.

  • The inorganic compositions of traditional lye, and lyes prepared from the stalks of five different agricultural products: beans, wheat, barley, buckwheat and red peppers, were analyzed. Traditional lye was composed mainly of a weak alkaline salt, potassium carbonate as the major component and neutral salts, potassium chloride and potassium sulfate as minor components. The ash and lye contents of buckwheat have significantly higher then those of the rest agricultgural products. Bean and red pepper stalks lyes were composed mainly of potassium carbonate, similar to the composition of traditional lye, but also contained potassium chloride or sulfate. In contrast, postassium chloride was the major component of wheat and barley stalk lye.

  • Soil microbial community analysis of farmland soil sprayed with lye in order to use fertilizer in Nigeria was performed. As a control, two kinds of soils not sprayed with lye, located in Eungo and Lagos with general practice in agriculture was selected. Soil sprayed with lye was pH 8.25 through alkalization reaction, while the other soil samples were pH 6.22 and 5.94. Substrate utilization and species diversity index of soil sprayed with lye were low than that of the other soils with the analysis of Biolog ecoplate. As a result of principal component analysis, the relationship between three samples was low. Microbial community analysis was performed by DGGE and most of them were soil uncultured bacterium. Especially, Uncultured Acidobacteria and Uncultured Methylocystis sp., which had been isolated from the rhizosphere of soybean grown in that site were discovered in the soil sprayed with lye.

  • This is a report on a total of 11 cases of esophageal perforation in the department of thoracic surgery, Chonnam University Hospital during the period of 8 years from 1962 to 1969. They occurred by the following agents, that is,lye solution[7 cases], fish bone[2 cases]. compress air [one case], strong acid [one case]. The perforated portions of esophagus were cervical esophagus in 2 cases, upper third of esophagus in 5 cases, middle third of esophagus in 3 cases and lower third of esophagus [abdominal esophagus] in one case. 4 cases out of cases of esophageal perforation after ingestion of Lye solution were due to Bougination to improve esophageal stenosis: 2 cases occurred 2 months after ingestion of Lye solution and the remaining 2 cases, 2 to 3 weeks after Lye solution ingestion. Therefore, It is realized that Bougination for esephageal stricture by Lye solution is particularly dangerous. The complication after esophageal perforation were mediastinitis,[10 cases], right pyothorax with mediastinitis [8 cases], peritonitis [4 cases], esophago-bronchial fistula[one case]. Owing to the various complications above mentioned, surgical approach to esophageal perforation is accordingly complicated and a combination of more than two of the following different procedures were properly used case by case, that is. gastrostomy or jejunostomy for feeding and esophageal rest,thoracotomy and chest drainage, lung decortication for pyothorax, primary closure of compress air perforation and esophago-bronchial fistula, mediastinostomy, retrosternal esophagoplasty using right colon to Lye stricture etc. 5 cases[45. 5%] of 11 cases were expired and the rest of 6 cases[54.5%]were survived with complete accomplishment of surgical procedures and satisfactory healing in 4 cases and interruption of follow up in 2 cases because of poor economical condition of the patients.

  • The caustic drugs are classified into acid and alkali. Oral intake of these drugs cause histological injuries to the surfaces of oral cavity, laryngopharynx, and esophagus. Caustic drugs such as detergents and brilliants are easily contacted at homes. However, until now, the epidemiology and the clinical statistics of caustic drug ingestion in Korea were not carried out. This is a case report of sodium hydroxide - lye, a caustic drug more toxic than the others - ingestion with complication of gastroesophageal perforation, rapidly progressed mediastinitis and prompt death in the course of treatment.

  • Baker's yeast(Saccharomyces cerevisiae) was used as a biocatalyst for eco-friendly indigo dyeing and the reducing power of yeast according to the alkaline solution type was compared. NaOH solution, lye, and buffer solution were used as alkaline solutions. The reducing power(K/S value, oxidation/reduction potential(ORP), pH) was monitored according to the elapsed time including the initiation of reduction, peak reduction, and the end of reduction. In all alkaline solutions, it was confirmed that yeast can be used reducing agent in indigo reduction dyeing. The pH stability and reducing power of buffer solution was better than that of NaOH alone. Although, pH and ORP stability of the reduction bath in lye were better than that of buffer solution, K/S value in buffer solution was higher compared to lye. The reducing power was different depending on the starting pH of the dye bath, and it was better when starting at pH 10.70 than at pH 11.30. Fastnesses to washing, rubbing, and light were relatively good with above rating 4. There was no significant difference in colorfastness depending on the type of alkaline solutions.

  • Caustic bums of the upper aerodigestive tract continue to be a significant clinical problem. Wide -field pharyngoesophagectomy is commonly performed as treatment for malignancies of the hypopharynx. A total laryngectomy is often necessary at the time of this procedure because of the anatomical proximity of the cancer or because of the likely compromise of swallowing postoperatively. When preservation of the larynx is attempted, aspirations after surgery frequently require a second-stage laryngectomy. And various flaps are using for reconstruction of esophageal defect. The choice of reconstruction is depended to the patient's status. A 54-year-old women whose symptom was severe dysphagia and X-ray revealed laryngopharyngeal stricuture. She had attempted suicide by swallowing lye liquids 32 years ago. She has entire laryngopharyngeal and esophageal stricutures. Total laryngectomy was performed and reconstruction of theesophagus was carried out with unusual reversed-gastric tube formation. Hence, we report this case with the review of literaturefor proper management in the future.

  • The various kinds of Hanji were manufactured by a few craftsmen at several provinces in Korea. It is very difficult to distinguish each others by its name so-called, Hanji, traditional Hanji, improved Hanji, mechanical Hanji and so on because the manufacturing process, raw materials and characteristics of Hanji are very different from each others. In this research, the functional properties of Hanji depending on the manufacturing process were evaluated and compared each others. The properties of Hanji was greatly changed according to grammage, lye and dochim. The higher the grammage resulted in the lower the pore size and the air permeability. Hanji made by NaOH and CaO showed relatively high brightness than that made by traditional lye(Yuokgae). Hanji treated with dochim can absorb high frequency(2,000 Hz) sound more effectively.
