Neck mass as a primary presenting sign is a common problem that physicians and surgeons alike have to face but conclusive diagnosis cna be made only by histopathological examination. During the period of four years from January 1988 to December 1991, three hundred sixteen diagnostic incisional or excisional biopsies of the neck masses were performed at the outpatient department of Surgery, Seoul National University Hospital and tissue diagnoses were confirmed by histopatholotical examination. On which a clinical analysis was performed and its results were compared with the results of one hundred fifteen Fine Needle Aspiration Cytologic examinations on neck masses during the same period. The results were as follows: In the histologic types of neck masses. inflammatory disease was the most common (58.2%), metastatic malignant tumor(22.5%), benign tumor(15.2%). primary malignant tumor(0.4%) in decreasing order. Among the individual lesions. tuberculous lymphadenitis was the most common(29.4%) and nonspecific lymphadenitis was the next. Of overall sexual distribution, female preponderated by a ratio of 1.15:1, but in the primary and metastatic malignancies, male did by a ratio of 1.60:1 and 1.53:1, respectively. The most common age group was third decade(26.8%), and fourth decade was the next(20.9%) but in malignant tumors. sixth decade was the most commom. The duration of symptom between one and three months(33.8%), was the most common and between three and six month was the next but the difference between the individual diseases was not significant. Of the metastatic tumor of seventy one cases, primary site was found in fifty cases(84.2%) and stomach cancer was the most comon primary site. In the result of the Fine Needle Aspiration Cytologic(FNAC) examinations, positive for mlignant cells was the most common(33.1%), following the frequencies with tuberculosis(22.6%), and nonspecific lymphadenitis(16.5%) in decreasing order. Eleven cases of FNAC underwent diagnostic biopsies and the diagnostic accuracy of FNAC was 83.3%. Conclusively, in our study, tuberculous lymphadenitis was the most common histologic type, female was predominant third decade was the most common age group. the duration of symptom between one and three month was the most common and in the metastatic tumors, stomach cancer was the most common primary site.

With the recent advances in instruments and techniques, laparoscopic procedure have extended to neonates with congenital anomalies. The author reports a 6-day-old boy with Hirschsprung's disease, treated successfully by the laparoscopic endorectall pull-through procedure. The technique and its potential role in the treatment of Hirschsprung's disease are described. One camera port and three working ports were used for access to the peritoneal cavity. The descending and sigmoid colon were mobilized laparoscopically. The submucosal dissection was done transanally. The colon was then pulled down in continuity, divided above the transition zone, and secured to the anal mucosa about 10 mm above the pectinate line. Author concluded that endorectal pull-through can be performed safety with the laparoscope.

The thyroid nodules are the most common endocrine disease requiring surgical management. We perfomed a clinical study of 298 cases with thyroid nodules, who were admitted to and operated at the Department of Surgery, College of Medicine, Gyeong sang National University from January 1987 to April 1997 and the results were summarized as follows: 1) Patients were composed of 214 cases(71.8%) of benign nodule and 84 cases(28.2%) of malignant nodule. Benign and malignant nodules were prevalent in fifth decade. 2) The sex distribution showed a preponderance of females with ratio of 5.88:1 in benign nodule and 11:1 in malignant nodule. 3) The nodules were located in the right lobe(134 cases, 44.9%), the left lobe(121 cases, 40.6%), both lobes(34 cases, 11.4%), and isthmus(8 cases, 2.7%). The possibility of malignancy was higher in the solid rather than cystic lesions. 4) Radioactive iodine scintiscans were perfomed in 273 cases and revealed cold nodules in 237 cases(86.8%), 58 of these cases(24.4%) were malignant. 5) According to the histopathologic classification, benign nodules included follicular adenomas 136 cases(63.5%), adenomatous goiters 67 cases(31.3%), Hurthle cell adenomas 4 cases(1.9%), cysts 3 cases(1.4%) and thyroiditis 4 cases(1.4%). In malignant nodules, papillary carcinomas 72 cases(85.7%), follicular carcinoma 8 cases(9.5%), undifferentiated carcinoma 2 cases(2.4%), medullary carcinoma 1 case(1.2%) and malignant lymphoma 1 case(1.2%). 6) The most commonly performed operative procedure was a lobectomy with isthmusectomy(85.5%) for bengn nodules and a total thyroidectomy(51.2%) for malignant nodules. 7) The rate of complications was higher in the cases with malignant nodules(20.2%) than in the benign cases(0.5%). The recurrence rate was 8.3%(7 cases).

해충저항성 Bacillus thuringiensis (Bt) 벼의 비표적곤충인 벼물바구미(Lissorhoptrus oryzophilus)에 대한 성충 전용살충제 Clothianidin 액상수화제의 살충제 감수성 시험을 실시한 결과, 72시간-LC50은 0.245 ml/L(95% 신뢰한계는 0.195~0.307 ml/L)이었으며, Bt벼의 모본으로 대조로 사용한 낙동벼의 72시간- LC50은 0.257 ml/L(95% 신뢰한계는 0.199~0.331 ml/L)이었다. 72시간-LC50은 낙동벼에서 다소 높았지만, 해충저항성 Bt벼 72시간-LC50이 낙동벼의 95% 신뢰한계 내에 포함되어, 두 품종의 LC50값에 유의성이 없는 것으로 판단된다. Insect-resistant transgenic rice, Bt rice was developed by inserting the mCry1Ac1, a modified gene from the soil bacterium Bacillus thuringiensis (Bt). For the biosafety assessment of this GM rice, we studied the effect on insecticide susceptibility of Rice Water Weevil (Lissorhoptrus oryzophilus) which is a nontarget insect pest and commonly used as a model organism in ecotoxicological studies. The Bt rice was confirmed to have the insertion of T-DNA and the protein expression by the polymerase chain reaction (PCR) and the ELISA analysis, As for the cumulative mortalities of Rice Water Weevil on insecticide, Clothianidin in Bt and non-GM counterpart, Nakdong rices were similar. The 72h-LC50 values of Bt and non-GM rices showed 0.245 ml/L and 0.257 ml/L respectively, As the 72h-LC50 vlaue of Bt rice was included within the 95% confidence limit of that of Nakdong rice slightly higher, the two varieties of the 72h-LC50 values were not significant, Thus, we found out there was a strong possibility that Bt rice didn`t affect the insecticide susceptibilities of nontarget insects.

Hepatoblastoma is the most common prirnary malignancy of the liver in children, occurring rnost frequently in infant younger than 2 years of age, however, massive hemoperitoneurn caused by spontaneous rupture of a hepatoblastoma is rare. Authours experienced a case of hemoperitoneum caused by spontaneous rupture of hepatoblastoma in a 42 month old male patient, who complained of abdominal pain.(Korean J Gastroentero11994; 26: 197 199)
