Eosinophilia is most frequently associated with asthma, allergic conditions, and parasitic infestation. Eosinophilia can also be associated with many forms of cancer. However, eosinophilia is infrequently associated with solid tumors. We experienced a 73-year-old-woman with eosinophilia as a manifestation of paraneoplastic syndrome that was combined with non-small-cell lung cancer (NSCLC). Initially, she was diagnosed with idiopathic hypereosinophilic syndrome, but was diagnosed with NSCLC 1 month later. Here, we report this case with a brief review of the literature.

Human cytomegalovirus (HCMV) glycoprotein H (gH) is one of target molecules in the human immune response to HCMV infection. This study was performed to rneasure the immune responses to HCMV gH in human sera by the expression of HCMV gH in eukaryotic cells. Amplified DNA from the gene encoding gH of HCMV by polymerase chain reaction was cloned into pcDNA3 to construct eukaryotic expression vector. Immunofluorescent staining revealed that the expressed gH in mammalian cells was reactive with the specific monoclonal antibody. Antibody titer in patient's sera with HCMV infection was measured with HCMV-infected fibroblasts and HCMV gH expressed in mammalian cells. Anti-HCMV gH antibody titer was higher in patient group than in healthy control group. There was no correlation between the antibody titer to the whole HCMV and neutralizing antibody titer, and between the antibody titer to whole HCMV and whole gH. Conclusively it is highly recommendable to use the defined antigen such as HCMV gH for the detection of antibody in HCMV-infected persons in the aspect of immunological properties.

BACKGROUND: Several factors affect the end-tidal carbon dioxide pressure (PETCO2) and increase the arterial to end-tidal carbon dioxide pressure gradient (Pa-ETCO2) during general anesthesia. We evaluated the relationship between age and Pa-ETCO2 during pneumoperitoneum in the steep Trendelenburg position in patients undergoing robot-assisted laparoscopic prostatectomy (RALP). METHODS: Ninety-two consecutive patients undergoing RALP were divided by age into a middle-aged (45-65 years) and an elderly (> 65 years) group. Anesthesia was standardized. Heart rate, mean arterial pressure, peak inspiratory pressure, lung compliance, minute ventilation, PaO2, PETCO2, PaCO2, and Pa-ETCO2 were measured 10 min after intubation in the supine position without pneumoperitoneum (T0); and 10 (T1), 60 (T2), and 120 (T3) min after pneumoperitoneum in the Trendelenburg position. RESULTS: Although PETCO2 did not change significantly during surgery, PaCO2 and Pa-ETCO2 increased gradually with time during pneumoperitoneum in the Trendelenburg position, and both parameters showed greater increases in the elderly than in the middle-aged group. Simple linear regression analyses revealed significant correlations between age and Pa-ETCO2 at T0 (P = 0.018), T1 (P = 0.006), T2 (P < 0.001), and T3 (P = 0.001). Linear mixed model analysis showed that Pa-ETCO2 was associated statistically significantly with age and duration of pneumoperitoneum in the Trendelenburg position, but age and duration of pneumoperitoneum in the Trendelenburg position were not associated (P = 0.090). CONCLUSIONS: The magnitude of Pa-ETCO2 during pneumoperitoneum in the steep Trendelenburg position increased with age, which could be attributed to age-related respiratory physiological changes.

Human cytomegalovirus (HCMV) has the ability to activate the espremission of many viral and cellular genes. Among various viral proteins, the immediate early proteins (IE1-72kDa, IE2-86kDa) have been known to be potent transactivators. The product of c-jun photo-oncogene is important in cell activation and differentiation. Here, we tried to find out if the IE could activate the c-jun promoter and also tried to identify the responsible sequence elements in the c-jun activation by IE1-72kDa. We found HCMV IE expression transactivated the c-jun promoter in human embryonal lung fibroblasts (HEL). The activation fold by IE1-72kDa, IE2-86kDa and IE2-55kBa was 23, 35, and 5, respectively. When the expression of each IE was combined, it showed synergism. Expression of (IE1-72kDa + IE2-86kBa) and (IE1-72kDa + IE2-86kDa + IE2-55kDa) resulted in 131 and 162 fold increase, respectively. The c-jun promoter region between -117 and -59 contains binding sites for the transcription factors Spl, CAAT, AP-1 like (ATF/CREB), and MEF2. Transient expression assays were performed using various reporter plasmids containing the c-jun promoter-regulatory region linked to the luciferase gene and a plasmic expressing HCMV IE1 gene. Deletional and point mutational analysis showed that the sequence between -225 to -160 and the CTF binding site were involved in the up-regulation of c-jun promoter.

Human cytomegalovirus (HCMV) gB is known to play important roles in cell surface attachment, virion penetration, spread of infection from cell to cell, and provocation of neutralizing antibody. This study was performed to determine the role of anti-HCMV gB antibody in overall neutralizing response in patients with HCMV infection and healthy control with past infection. HCMV gB was stably expressed in 293 cells. With the stable cell line expressing gB as a specific immunosorbent, anti-gB antibody was removed from the current and past HCMV-infected sera and the remaining neutralizing activity was measured by plaque assay. It was shown that 19-50% of the total virus-neutralizing activity of sera with past HCMV infections was derived from anti-gB antibody, but anti-gB antibody had little effect on the total serum virus-neutralizing activity in patients currently infected with HCMV. This result suggests that neutralizing antibody to HCMV gB may reflect disease status.
