<P><B>Purpose</B></P><P>Pathological diagnosis involves very delicate and complex consequent processing that is conducted by a pathologist. The recognition of false patterns might be an important cause of misdiagnosis in the field of surgical pathology. In this study, we evaluated the influence of visual and cognitive bias in surgical pathologic diagnosis, focusing on the influence of “mental rotation.”</P><P><B>Materials and Methods</B></P><P>We designed three sets of the same images of uterine cervix biopsied specimens (original, left to right mirror images, and 180-degree rotated images), and recruited 32 pathologists to diagnose the 3 set items individually.</P><P><B>Results</B></P><P>First, the items found to be adequate for analysis by classical test theory, Generalizability theory, and item response theory. The results showed statistically no differences in difficulty, discrimination indices, and response duration time between the image sets.</P><P><B>Conclusion</B></P><P>Mental rotation did not influence the pathologists' diagnosis in practice. Interestingly, outliers were more frequent in rotated image sets, suggesting that the mental rotation process may influence the pathological diagnoses of a few individual pathologists.</P>

The effects of red ginseng extracts (RG) and γ-aminobutyric acid (GABA) on immunostimulatory activity and tumor metastasis inhibition in mice were investigated. The proliferative activity of splenocytes was significantly higher in the RG + GABA (RG-GA) group than in RG or GABA alone. The RG-GA-administered group showed increased production of interleukin (IL)-6 and GM-CSF compared to that in the RG or GABA groups. BM cell proliferation was significantly induced when the supernatant of Peyer’s patch cells obtained from GA-RG group was added. In the experimental tumor metastasis model, RG-GA treatment produced a significant anti-tumor metastatic effect. In addition, oral administration of RG-GA not only increased the cytotoxic activity of NK cells against YAC-1 cells, but also significantly increased IFN-γ and granzyme B concentrations in the culture supernatant. The blood level of interferon-γ, IL-17, and IL-21 were significantly higher in RG-GA group compared to monotreated group. Therefore, RG has a synergistic effect with GABA that enhances the host defense system against foreign materials. This research was funded by Ministry of SMEs and Startups.
