This study was conducted to investigate the detrimental effects of decapping and emasculation on the postharvest quality and the vase life of cut Cymbidium flowers with or without 1-Methylcyclopropene (1-MCP) and Aminoethoxyvinylglycine (AVG) treatments. The vase life treated by 1-MCP 150 ppb for four hours regardless of decapping or emasculation was significantly prolonged 12 days more. Ethylene production in the treatment without 1-MCP began to be raised from 7days, 1-MCP treatments, regardless of the concentration of processing did not occur until 15days. Ethylene began to production when the lip began to coloration. Compared to the 1-MCP effect, the AVG treatment of 0.5 and 1mM for four hours prolonged the vase life about nine days more. Whereas, the only decapping or emasculation treatments were effective to more three days longer in the vase life of cut Cymbidium' Halleluiah' flowers. 1-MCP treatment was very beneficial for Cymbidium 'Halleluiah' cut flowers than AVG.

Ten cases with esophageal foreign body were treated surgically from July 1980 to October 1995 at the Departme t of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The mean age was 45.3 years, with a range from 25 to 71. Out of ten cases, 6 were female and four were male. Common symptoms were dysphagia, fever, foreign body sensation and neck pain. Three cases of foreign bodies were of fish bones, two of bubble paclcage of drugs, one case of a Eeer bottle cap, one of a piece glass, one of a bathtub plug, one of chicken and one of a bean. The diagnosis was established by esophagography using a water soluble contrast material and esophagoscopy. Among of ten cases, two had esophageal stricture due to the ingestion of Aye at a young age. One case had experienced psychological problems. All foreign bodies were removed by surgical procedures. Five cases were treated by cervical esophagostomy, one case by right thoracotomy, one case by retrograde bougienation through gastrostomy and two cases by cervical incision and drainage for cervical abscess. Three cases developed pos operative esophageal leaks which healed spontaneously and transient hoarseness developed in one case. One case developed traumatic pneumothorax and subcutaneous emphysema which was treated by closed thoracostomy. There were no operative deaths. C(ocean J Thorac Cardiovasc Surg 1997;30:1117-20)
