Metastatic squamous cell carcinoma from a cancer of unknown primary (CUP) affecting the intrathoracic lymph node is very rare. We reported a case of metastatic squamous cell carcinoma in the hilar and interlobar lymph node from a patient with CUP and reviewed the associated literature. Abnormal mass in the right hilar area was incidentally detected. A chest computed tomography scan showed a 2.5-cm diameter mass in the right hilum that had changed little in size for 3 years. The patient underwent a right pneumonectomy and mediastinal lymph node dissection. A metastatic squamous cell carcinoma in the hilar and interlobar lymph nodes without a primary lung or other lesion was diagnosed. The patient received adjuvant chemotherapy for a diagnosis of T0N1M0 lung cancer.

Adenoid cystic carcinoma usually grows in the trachea or near its bifurcation and causes obstruction of the air way. We recently experienced a 33 year-old male patient who had adenoid cystic carcinoma in the left main bronchus with the chief complaint of productive cough. On the bronchoscopy, the mass obstructed the left main bronchus completely and had nodularity and increased vascularity.The trachea was shifted to the left side and the lower lobe of the left lung was atelectatic on chest X-ray and computed axial tomogram.He underwent left tracheal sleeve pneumonectomy and lymph node dissection through bilateral thoracotomy. At first,we attempted left tracheal sleeve pneumonectomy through the left thoracotomy,however, it was very difficult to perform carinoplastic procedure after sleeve resection of 2.5cm of distal trachea and 1cm of proximal right main bronchus including whole left lung because of poor operative field and difficulty in the anastomosis of the right main bronchus to the distal end of the trachea without tension.Therefore after radical resection of the left lung we made right thoracotomy,through which we could anastomosed the distal trachea and right main bronchus with 4-0 PDS interrupted suture after mobilization of the right hilum without difficulty. The tumor was confirmed to be adenoid cystic carcinoma with metastasis to subcarinal lymph node histopathologically. Postoperative course was uneventful but he needed two bronchoscopic procedure to clear distal airway of the retained bronchial secretion. He was discharged at 14 days after operation with complete recovery.

We report a patient with combined hepatocellular-cholangiocarcinoma confined in the common hepatic duct and scirrhous type of hepatocellular carcinoma in the caudate lobe of liver simultaneously. The patient was a 55-yearsold Korean man with hepatitis B virus (HBV) carrier who was referred from a local hospital due to detected liver mass on abdominal computed tomography (CT). He has presented jaundice and weight loss for the previous 3 weeks. Laboratory examination showed AST/ALT elevation and hyperbilirubinemia. HBsAg was positive. The tumor marker study showed elevated AFP and DCP, not CEA and CA 19-9. Abdominal CT disclosed an about 2.1×0.9 cm sized soft tissue density in hilum with both intrahepatic duct (IHD) dilatations and an about 3×2.1 cm sized arterial enhancing lesion at segment 8 of the liver. Patient received 15 cycles of Gemcitabine/Cisplantin chemotherapy from February 27, 2013 to December 31, 2013. Caudate lobectomy of liver, segmental resection of bile duct and Roux-en-Y hepaticojejunostomy was performed on February 10, 2014. The final pathologic report showed double primary liver cancer, combined hepatocellular-cholangiocarcinoma in common hepatic bile duct and scirrhous type of hepatocellular carcinoma in segment 1 of the liver. This is a very unusual case in which combined hepatocellular-cholangiocarcinoma confined in the large bile duct and two rare hepatic cancers coexisted.

Introduction: Sialolithes are initiated by localized deposition of calcified material in the salivary glands. And that may even cause various symptom especially swelling and pain. This study purposes to collect statistical data of sialolithiasis for clinical analysis. Materials and Methods: Among forty seven patients who have visited Seoul National University Dental Hospital during 2004-2009, patients' age, sex, location and size of stone, radiodensity of stone, symptom, surgical procedure were investigated. Statistical correlation between size, location, symptom was evaluated. Chemical composition was analyzed for 3 sialolithes. Results: The average age was 41.4 years. Sialolithiasis had slight female predilection (57.4%). Most cases occurred in the submandibular glands (91.5%). And most cases had radiopaque features (95.8%). The average size was 7.17 mm. The most frequent location of the stones were the duct orifice and the submandibular gland hilum (16 cases in each), followed by the middle part of the duct (n=8), the intraglandular area (n=4), and the proximal part of the duct (n=3). Eleven cases were asymptomatic. Thirty six cases had complaints of pain, swelling, hardness, and decrease in saliva flow (multiple symptoms). Various methods of surgery was performed. Two cases were self-removed. Thirty seven cases underwent procedure involving stone removal alone. Six cases underwent gland extirpation, and two cases underwent ductoplasty. Conclusion: There was no statistical correlation between size, location, and symptoms. Sialolith was composed of Ca (58.5-69.3%), P (30.7-35.7%), organic material, and trace inorganic material.

본 연구에서는 종자전염병의 무독화를 위해 실시하는 건열처리에 의한 종자의 활력감소를 회복시키기 위한 방법을 개발하고자 하였다. 건열처리된 종자의 활력감소 정도는 작물과 품종에 따라 다양하게 나타났다. 일반적으로 호박 종자가 박 종자에 비하여 활력이 덜 감소하였다. 건열처리된 종자를 0, 30, 120일간 후처리하였을 때, 발아율은 건열처리 후처리 기간이 증가함에 따라 높아졌는데, 후처리 효율은 작물과 품종에 따라 상이하였다. 또한, 박과 호박 종자를 상향 또는 수평 파종 시 하향 파종보다 높은 종자활력과 묘소질을 보였다. 따라서 건열처리에 의한 종자활력의 감소는 적절한 후처리 뿐만 아니라 상향파종을 통해서도 효과적으로 회복시킬 수 있음을 확인하였다.

Seeds of medicinal soybean [Glycine max(L.) Merill] are characterized by a black seed coat, white stripe at hilum border, yellow cotyledon, and very small seed weight. Production of this medicinal soybean has recently increased as a consumption increased. The objective of this study was to evaluate the growth characteristics and seed yield of collected medicinal soybeans and to obtain basic information on production practices and breeding materials. The collected medicinal soybean lines were cultivated at three locations for two years. Twenty-seven lines were planted at the Research Farm, Korea University, Namyangju city, on May 23, and at the Research Farm, Kyungpook National University, Taegu, on May 20, 1995. In 1996 field experiments, forty-four lines were planted on May 25, at Research Farm, Korea University, and twenty-seven lines among those were planted on June 7 at the Research Farm of National Yeongnam Agricultural Experiment Station, Milyang city. The investigated lines had purple or white flower. Flowering and maturing dates were similar or later than those of the control cultivars. Branch number was greater for the investigated lines. One hundred-seed weight of the lines ranged from 8.5 to 15.0 g. Mean seed yields ranged from 1.54 to 2.89 MT/ha. Nine lines of the investigated medicinal soybeans showed higher yield capacity than the control cultivars. Further research should be done on the improvement of the production system and breeding program of medicinal soybeans.

Sialolithiasis is the most commom disease of salivary gland. The main symptoms are pain and swelling of the involved gland during eating. It can occur at any age but patients in their third to fifth decade present most cases. Males are more frequently affected than females. Most sialoliths are located within the duct system of the submandibular gland. Submandibular sialoliths close to the hilum of the gland tend to become large and ovoid shape, whereas sialoliths in the duct tend to be elongated. Commonly, sialoliths measure from 1 mm to less than 10 mm, and larger than 15 mm are considered rare. In one case we have removed a giant sialolith which was located in a wharton's duct and in the other case we have removed multiple sialolith including a giant sialolith which were also located in a Wharton's duct. We report these 2 cases with literature reviews.

The simultaneous occurrence of a gastrointestinal stromal tumor (GIST) and a gastric adenocarcinoma is uncommon, and has rarely been reported in the literature. The present report describes the case of a 74-year-old male patient who initially presented with an adenocarcinoma that had invaded the antral mucosa. Computed tomography then revealed the presence of a suspected GIST, in the form of a $2{\times}2$ cm mass at the hilum of the spleen. In view of the advanced age of the patient, a surgical approach that would minimize risk and maximize quality of life was preferred. The patient therefore underwent simultaneous laparoscopy-assisted distal gastrectomy for the adenocarcinoma and wedge resection for the GIST. This approach was only chosen after confirming that it would be possible to preserve three or more of the short gastric arteries that supply the area below the wedge resection site. This may be considered a feasible apapproach to the management of the simultaneous occurrence of a mid-to-low gastric body adenocarcinoma and a high gastric body GIST.
