Background: In the last few decades, numerous efforts have been made to develop a better mouse model to overcome the current limitations of laboratory inbred mouse models such as have a weaker and simpler immune status. As part of these efforts, in Korea, the Hallym university medical genetics research team has been developing a new inbred strain of Korean wild mouse KWM/Hym. It was suggested that this strain, which is derived from wild mice, might be useful for genetic research and may become a valuable tool for overcoming some limitations seen in inbred mice that are currently used in the laboratory. Furthermore, for this study, we aimed to determine the visual phenotype of this unique strain KWM/Hym, and consider whether and if they are suitable for visual research. To analyze their visual phenotype, we performed the functional and morphological examinations in KWM/Hym mice and compared the results with laboratory mice which are the most common background strain. Results: KWM/Hym had a thin corneal phenotype, thin but well-ordered retina due to their light body weight characteristic, and normal visual function similar to control mice. Unexpectedly, the KWM/Hym mice developed cataracts only at around 25 weeks old. Conclusions We suggest Korean wild mouse KWM/Hym is useful for visual experiments and could be an animal model of eye disease in humans.

Purpose: This study aimed to determine whether micro-flow imaging (MFI) offers diagnostic performance comparable to that of contrast-enhanced ultrasonography (CEUS) in detecting segmental congestion among patients undergoing living donor liver transplantation (LDLT). Methods: Data from 63 patients who underwent LDLT between May and December 2022 were retrospectively analyzed. MFI and CEUS data collected on the first postoperative day were quantified. Segmental congestion was assessed based on imaging findings and laboratory data, including liver enzymes and total bilirubin levels. The reference standard was a postoperative contrast-enhanced computed tomography scan performed within 2 weeks of surgery. Additionally, a subgroup analysis examined patients who underwent reconstruction of the middle hepatic vein territory. Results: The sensitivity and specificity of MFI were 73.9% and 67.5%, respectively. In comparison, CEUS demonstrated a sensitivity of 78.3% and a specificity of 75.0%. These findings suggest comparable diagnostic performance, with no significant differences in sensitivity (P=0.655) or specificity (P=0.257) between the two modalities. Additionally, early postoperative laboratory values did not show significant differences between patients with and without congestion. The subgroup analysis also indicated similar diagnostic performance between MFI and CEUS. Conclusion MFI without contrast enhancement yielded results comparable to those of CEUS in detecting segmental congestion after LDLT. Therefore, MFI may be considered a viable alternative to CEUS.
