Computed tomographic lymphography predicts the difficulty of sentinel lymph node biopsy with dye.

Background: Sentinel lymph node biopsy (SLNB) has been a method of choice for treating breast cancer. Computed tomographic lymphography (CT-LG) provides a view of the sentinel lymph node (SLN) with the detailed lymphatic anatomy preoperatively, and the SLN is easily identified during SLNB. In this article, we examined the usefulness of CT-LG to predict the difficulty of SLNB with the dye method.

Effects of streptococcal preparation OK-432 on liver regeneration and energy status after partial hepatectomy under ischemia/reperfusion in rats.

Background/aims: Activation of reticuloendothelial system functions by the treatment with OK-432 has been reported to enhance liver regeneration. However, its effect on liver regeneration has not been studied after hepatectomy under ischemia/reperfusion which is in clinical use. The aim was to examine the effect of OK-432 on regeneration and energy status of the liver after hepatectomy under ischemia/reperfusion in rats.
