To demonstrate the quality assurance of the comprehensive examination of sixth-year students at Nippon Medical School, 4 undergraduate examinations were compared with the national examination for medical practitioners (NEMP) using scatter graphs and Pearson's correlation coefficient. Of the 93 sixth-year students at Nippon Medical School, 57%(n=53) reported their scores on the NEMP in response to a request from the Academic Quality and Development Office. Correlation coefficients of the grade point average (years 1 to 5), average scores on graduation examinations of 24 subjects, scores on the trial examination of NEMP, and scores on the sixth-year comprehensive examination with overall scores on the NEMP were 0.62, 0.46, 0.68, and 0.63, respectively. These results suggest that the sixth-year comprehensive examination is more suitable than are graduation examinations for predicting the NEMP score.

To demonstrate the quality assurance of comprehensive examinations for fourth-year students at Nippon Medical School, scores on comprehensive examinations were compared with those on a trial of computer-based testing (CBT) of a nationwide medical and dental student evaluation system in 2003. Pearson's correlation coefficients between scores of two comprehensive examinations and the CBT score were 0.45 and 0.67, and the correlation coefficient between the average score of the two comprehensive examinations and the CBT score was 0.55. Fourth-year comprehensive examinations are useful tools for summative evaluation and prediction of CBT performance.

Granulocyte colony stimulating factor (G-CSF) restores neutrophil count in patients with chemotherapy-induced neutropenia. G-CSF can also induce production of epithelial neutrophil activating protein-78 (ENA-78) and interleukin-8 (IL-8), chemotactic factors from neutrophils in vitro. This study was purposed to investigate whether this effect is also observed in vivo. 10 lymphoma patients were selected who received chemotherapy and G-CSF (nartograstim) administration. Blood was obtained before chemotherapy [Time Point 1 (TP1)], at neutropenic phase before G-CSF administration (TP2), and at neutrophil recovery phase after G-CSF (TP3). ENA-78 and IL-8 mRNA in neutrophils were quantified by real-time PCR. Phagocytosis and reactive oxygen species (ROS) generation were examined by flow cytometry. The results showed that ENA-78 and IL-8 mRNA expression at TP2 increased in 5 and 8 patients, respectively. The ENA-78 mRNA expression at TP3 was increased in 3 and decreased in 6 patients, and IL-8 mRNA expression at TP3 decreased in 7 patients. G-CSF did not affect phagocytosis and normalized ROS generation in all of the patient. It is concluded that increase of ENA-78 and IL-8 expression in neutrophils is common in chemotherapy-induced neutropenic patients. G-CSF administration does not significantly increase ENA-78 and IL-8 expression.
