Recently, cell cycle regulators have been suggested as new prognostic factors of the lung cancer. In this study, we evaluated the expression of cyclin D1, p21, and p53 using the X2-test, with regard to the stage of the patients, histologic type, and histologic differentiation in the 135 cases of non-small cell lung carcinomas (NSCLC). To evaluate the confounding effects among cyclin D1, p21, and p53 on X2-test analysis, we used the Mantel-Haenzel test. The NSCLC in this study included 82 cases of squamous cell carcinoma and 53 cases of adenocarcinoma. Each nuclear staining of cyclin D1, p21, and p53 was observed in 65 cases (48.1%), in 54 cases (40.0%), and in 81 cases (60.0%) of NSCLCs, respectively. Only p53 expression was significantly associated with the stage (stage I, II, IIIa) (p<0.05) and squamous cell carcinoma (p<0.05). On the other hand, cyclin D1 expression was significantly associated with the histologic differentiation. The confounding effects among cyclin D1, p21, and p53 revealed that only p21 expression changed the relationship between p53 and stage. In this regard, further study is needed.

PURPOSE: Early diagnosis of neonatal sepsis is very difficult because of no specific clinical and laboratory findings. It also takes at least 48 hours of incubation period to isolate the organism by culture study. So several laboratory tests have been evaluated for their usefulness in rapid detection of the neonatal sepsis. Those are evaluated either singly or in combination with a defined scoring system include leukocyte count with differential count, platelet count, C-reactive protein level, erythrocyte sedimentation rate, haptoglobin level, fibronectin level, leukocyte alkaline phosphatase and so on. But no single test or combination with others has proved superior to the leukocyte count and differential count as a reliable indirect indicator of neonatal bacterial infection. We performed this study to determine the appropriate screening test for early detection of neonatal sepsis. METHODS: During the period of May 1991 through April 1997, we selected 200 neonates who were admitted to the neonatal intensive care unit of Kon-Kuk University Medical Center Seoul Hospital. All of the cases were retrospectively evaluated and divided two groups; sepsis group-88 neonates who were confirmed by blood cultures, and control group-112 neonates who had no evidence of neonatal bacterial infection. RESULTS: The results were as follows; 1) The sex ratio of male to female was 1.5:1 in the sepsis group and showed significant difference between two groups (P<0.05). The incidence of neonatal sepsis in prernature infant was higher in sepsis group than control group (P<0.05), and mean body weight was lower in sepsis group (2351.4148.3g) than control group (Z821.8 142.6g) significantly (P<0.05). 2) Predisposing perinatal factors associated with neonatal sepsis were premature rupture of membrane (> or = 24hrs) (14.5%) meconiurn staining (6.8%), asphyxia (Apgar score < or = 6 at 5mins) (5.7%), eclampsia and preeclampsia (4.5%), maternal infection (3.4%) and bleeding (including placenta previa, abruptio placenta) (1.1%) in order of frequency. Among th, only premature rupture of membrane was significant difference between two groups (P<0.05). Others risk factors including umbilical catheterization, endotracheal intubation, ventilatory care, total parenteral nutrition were also signi- ficant difference between two groups (P<0.05). 3) The common presenting symptoms of neonatal sepsis were jaundice (48.9%), poor feeding (45.5%), ternperature instability (43.2%), lethargy (30.7%), irritability, dyspnea, diarrhea, vomiting, tachypnea, and cyanosis in order of frequency. Among the above symptoms, poor feeding, dyspnea and cyanosis were significant difference between two groups (P<0.05). 4) The peripheral blood findings (leukocyte count, platelet count, ESR) showed no significant differences between two groups (P>0.05). The acute phase reactants (APR) score above two (37/88) and positive C-reactive protein (51/88) in the sepsis group were regarded as significantly high compared to the control group. 5) In the cases with APR score above two including positive C-reactive protein and abnormal total leukocyte count, sensitivity was 17.0%, specificity 97.3% positive predictive predictive value 83.3%, and negative predictive value 60.0%. CONCLUSIONS: The higher frequency of neonatal sepsis was proved in the cases of APR score above two including positive C-reactive protein. In the cases with abnormal total leukocyte count and APR score above two including positive C-resctive protein, the specificity was 97.3% and the positive predictive value was 83.8%. So APR score above two including positive C-reactive protein and abnormal total leukocyte count could be regarded as an useful test method for early detection of neonatal sepsis.

Tularemia is a zoonosis caused by Francisella tularensis. It is primarily a disease of wild animals. Human infection is incidental and usually results from interaction with biting or blood-sucking insects, wild or domestic animals, or the environment. An increasing number of cases have been reported in several countries. However, in Korea it has not been reported until now. A 40-year old male patient visited our department on Jan 13, 1997, complaining of multiple swollen lymph-nodes on his axillae and reddish swollen left upper arm which contained an abscess at its central portion for about ten days. On Dec 25, 1996, he found a dead wild rabbit on a nearby mountainside, ate it after cooking it by himself with his hands injured. His abscess was drained and microbiologic examination was done. However no microorganism was isolated. His lymph nodes were surgically removed from both axillae, and we investigated them microbiologically and pathologically. On microbiologic examination, small aerobic gram negative coccobacilli were grown on a chocolate agar plate in an aerobic condition with 5% CO2 at 37 degrees centigrade. On H & E staining, the lymph node showed chronic granulomatous inflammation. We sent the microorganism and lymph nodes to the Centers for Disease Control and Prevention in the United States of America for the definitive diagnosis. Finally the microorganism was identified as F. tularensis by culture morphology, biological tests and immunohistochemical staining. We report the first case of F. tularensis in Korea.

BACKGROUND: The enteroviruses are the most common etiologic agent of aseptic meningitis in adults and children. The incidence of enteroviral meningitis in childhood meningitis is up to 80%, but in adults is not known, worldwidely. In Korea, where tuberculosis is endemic, the rapid and accurate diagnostic method for enteroviral meningitis is required especially because early differential diagnosis of viral meningitis from tuberculous meningitis is very important. The aims of this study were the demonstration of enteroviruses from cerebrospinal fluid (CSF) of adult patients with aseptic meningitis by PCR/Southern hybridization and the verification of the usefulness of PCR/southern hybridization as a rapid diagnostic tool. METHODS: From July 1992 to June 1995, total 34 CSF samples (10 from children, 24 from adults) of patients with aseptic meningitis were studied. As a control group, 15 patients with tuberculous meningitis and 15 patients with bacterial meningitis were studied. Viral RNA was extracted from CSF, reverse transcriptied into cDNA and amplified. The PCR products were Southern hybridizied with enteroviruses-specific digoxigenin-labelled probe. RESULTS: 16/24(66.7%) samples of adult patients with aseptic meningitis were positive for enteroviruses, while in child patients with aseptic meningitis, 9/10(90%) samples were positive. And in one patient, PCR was positive from asymptomatic, onset-7th day CSF sample. CONCLUSION: Enteroviruses were the most common causative organisms of adult aseptic meningitis in Korea. And, this study showed the usefulness of PCR/Southern hybridization of enteroviruses from CSF for etiologic diagnosis of adult aseptic meningitis in subclinical, asymptomatic period.
