The scanner is a subroutine which is frequently called by an application program like a compiler. The primary function of a scanner is to combine characters from the input stream into recognizable units called tokens. A method has been presented in this paper for designing such a scanner, also frequently referred to as a lexical analyzer in the current literature. The major steps involved in this design process are: identification of tokens, construction of a state diagram, building drive tables and finally writing a scanning routine. The rules for generating the driver tables are described and an algorithm for the scanner, utilizing these driver tables, is included. The method has been successfully used to build the system scanner for a user oriented small language. It is concluded that the method is well defined, gives rise to a modular design and as such easily lends itself to language extensions.

To investigate the effects of smoke liquid method and smoking method on the yield, palatability, physical characteristics, shrinkage during storage, changes in pH and color, and charge in volatle basic nitrogen concentration of pork sausage, a series of experimentation was conducted to establish a new method involved in producing smoke liquid and to compare the quality of pork sausage produced by two methods described above. Productivity and characteristics of crude and refined smoke liquid prepared from chestnut tree and oak tree were studied for the first phase of studies. Added level of smoke liquid was 0.4, 0.8, 1.2%. Results obtained are summarized as follows: (1) It was found that oak tree produced more smoke liquid than chestnut tree did. Yield of crude smokeliquid from oak tree and chestnut tree was 43.30% and 36.39%, respectively and that of refined smoke liquid from oak and chestnut was 38.88% and 31.81%, respectively. (2) However, the density of smoke liquid obtained from chestnut was higher than that from oak. Data revealed that the density of crude and refined spoke liquid prepared from oak tree was found to be 1.029-1.031 and 1.009-1.011, respectively, and that from chestnut tree was 1.042 and 1.010, respectively. (3) Reflection rate of crude and refined smoke liquid manufactured from oak tree was measured to be 1.354-1.308 and 1.342-1.343, respectively and that from chestnut was found to be 1,355 and 1.344, respectively. (4) The pH of crude and refined smoke liquid obtained from chestnut tree was 2.20-2.67 and 1.59, respectively and that from oak tree was 2.65 and 1.66 respectively-. (5) Acidity measured as acetic acid concentration of crude and refined smoke liquid prepared from chestnut tree was measured to be 6.08-9.50% and 8.98-9.30%, respectively and that from oak tree was 5.39 and 7.20, respectively. (6) Average yield of pork sausage processed by the smoke liquid method (96.85%) was significantly (P$lt;0.01) higher than that by smoking method (90.75%). (7) Palatability measured as panel score of pork sausage processed by the smoking method was superior to that by smoke liquid method. However, it was found that addition of smoke liquid at the level of 0.8% resulted the highest (P$lt;0.01) panel score among the pork sausages process^d by smoke liquid. Palatability of sausage was not affected by the wood material used for the smoke liquid. (8) Average values of hardness, chewiness and gumminess of pork sausage was not affected by the method of processing. (9) Weight loss due to shrinkage during storage period was slightly higher for smoke liquid method (24.02-28.30%), than for smoking method (22.58-24.93%) with no statistical difference. (10) Increase in pH after storage period of 21 days for smoking method and smoke liquid method (6.30-6.37 and 6.62-6.83) was noticed when it was compared with 0 day storage (5.72-5.98 and 6.25-6.35). (11) Color of sausage processed by smoking method was measured to be 75.66-80.66 and that by smoke liquid was 60.00-66.00 at 0 day of storage and about the same degree of discolorization was observed after 19 days of storage. (12) No significant difference w-as found between two methods cf sausage processing in the concentration of volatile basic nitrogen, although the concentration was increased as the storage period of sausage progressed. (13) Present data indicate that the correlation effects between pH and color was estimated to be. r=-0.749, pH and volatile basic nitrogen was r=0.6493 and valatile basic nitrogen and color w-s r=-0.8531, respectively.

기관지천식, 결체조직 질환 및 간경변증 환자에서 Extracellular Phospholipase A_2 의 활성도

이종명,김능수 慶北大學校 醫科大學 1996 慶北醫大誌 Vol.37 No.3

목적 : Phospholipase A_2(PLA_2)는 염증반응에서 중요한 역할을 하는 칼슘의존성 지방분해효소로서 염증성 cytokine 및 내독소 등에 의해 세포외로 유리된다. 본 연구의 목적은 염증성 cytokine이나 내독소가 병태생리에 관여하는 것으로 알려진 기관지천식, 류마치스 관절염, 홍반성 낭창 (SLE)및 간경변증 환자에서 세포외성(extracellular) PLA_2의 활성 정도를 알아보는데 있다. 대상 및 방법 : 기관지천식 환자 79명, 류마치스 관절염 환자 41명, SLE 환자 26명 및 간경변증환자 21명을 대상으로 혈청과 체액에서 PLA_2 활성도를 측정하고 이를 임상소견과 비교 검토하였다. 결과 : 혈청 PLA_2 활성도는 기관지천식, 류마치스 관절염, SLE및 간경변증 환자군 모두에서 정상 대조군보다 유의하게 증가되어 있었으며, 기관지천식과 간경변증 환자군의 경우 병의 중증도에 따른 혈청 PLA_2 활성도의 차이도 유의하였다. 류마치스 관절염 환자의 관절액과 간경변증 환자의 복수에서도 높은 PLA_2의 활성이 관찰되었으며 이는 혈청 PLA_2의 활성도와 유의한 상관관계를 보였다. 결론 : 세포외성 PLA_2의 활성도는 기관지천식, 결체조직 질환 및 간경변증 환자에서 증가되어 있으며 이는 PLA_2가 이들 질환의 병태생리에 관여함을 시사한다고 생각된다. Phospholipase A_2(PLA_2) is a group of lipolytic enzymes which catalyze the hydrolysis of the sn-2 acyl ester bond of phosphoglycerides to produce free fatty acids and lysophospholipids. The enzymes are widespread in nature and occur in both cell-associated and extracellular forms. To date, there are at least 2 types of PLA_2s(pancreatic and non-pancreatic), which are different in their structure and function. Increasing evidences indicate that extracellular PLA_2 of non-pancreatic type may contribute to the pathogenesis of inflammatory diseases. Although little is known about the exact mechanisms of the release of these enzymes, endotoxin and inflammatory cytokines such as TNF & IL-1 can induce the extracellular release of PLA_2. To elucidate the roles of extracellular PLA_2 in inflammatory diseases and to determine the activities of the enzymes in liver cirrhosis (in where endotoxemia can be seen due to decreased clearance by reticuloendothelial cells), we measured extracellular PLA_2 activities in patients with bronchial asthma, rheumatoid arthritis, SLE and liver cirrhosis. Serum PLA_2 activities of all of the above groups were significantly higher than those of healthy controls and in case of bronchial asthma and liver cirrhosis, there was a significant difference in their activities according to disease severity. It was also founded that the activities of the enzymes were very high in synovial fuid of rheumatoid arthritis patients and in ascitic fluid of liver cirrhosis patients. These results suggest that extracellular PLA_2 exerts an important roles in the pathophysiology of bronchial asthma, connective tissue diseases and liver cirrhosis. Therefore the regulation of the synthesis and release of PLA_2 from inflammatory cells may contributes to management of the diseases. Further studies are needed to clarify the mechanism and clinical significance of increased PLA_2 activities in patient with advanced liver cirrhosis.

Objective : Cyclooxygenase-2, the inducible isoform of prostaglandin H synthesis, has been implicated in the growth and progression of a various human cancer. Although COX-2 overexpression has been observed in human gliomas, the prognostic or clinical relevance of this overexpression has rarely been investigated to date. Methods : We examined COX-2 expression by immunohistochemistry in tumor specimens from 25 patients with low- and high grade astrocytomas and correlated the grade of COX-2 expression with patients survival. Results : Immunohistochemical staining results were as follows : negative staining, N=4(16%), positive staining, N=21(84%). Results of low grade astrocytoma(N=10) were as follows : negative staining, N=3(30%), weak positive staining, N=7(70%). Anaplastic astrocytomas(N=4) as follows : negative staining, N=1(25%), weak positive staining, N=3(75%). Glioblastomas(N=11) as follows : negative staining, N=0(0%), weak positive staining, N=5(45%), strong positive staining, N=6(55%). As a group, tumors with higher rate of cell proliferation tended to have increased expression of COX-2. The percentage of COX-2 expression were associated with a worse survival rate(p=0.0028), and the grade of astrocytic tumors(p=0.001). These findings indicate that high COX-2 expression in tumor cell is associated with clinically more aggressive gliomas, and is a strong predictor of poor survival. Conclusion : Our study provides evidence that COX-2 is up-regulated in the majority of high-grade gliomas and that increased COX-2 expression is a significant negative predictor of survival and selective COX-2 inhibitors may have a potential role as an adjuvant therapy of astrocytic tumors.
