We examined the site-specific implantation of cancer cells in peritoneal tissues after an i.p. inoculation of 10(5) P388 leukemia cells. Twenty-four h after the inoculation, the number of viable cancer cells infiltrating into specific tissue sites of the peritoneum was estimated by an i.p. transfer method. A descending order of tissue implantation with(More)
To investigate the site-specific implantation of cancer cells in peritoneal dissemination, we inoculated CDF1 mice intraperitoneally with mouse P388 leukaemia cells labelled with bromodeoxyuridine (BrdU) and then observed immunohistochemically the distribution of the cells in the greater omentum taken from the mice using an anti-BrdU antibody. We found the(More)
Omental milky spots are omentum-associated lymphoid tissues that cede peritoneal macrophages and participate in the immunity of the peritoneal cavity. We studied the changing surface features of milky spots and milky spot macrophages of Wistar rats, following the i.p. administration of OK-432, a killed streptococcal preparation (1 Klinische Einheit (unit)(More)
A method is described for flat-embedding thin membranous tissues in Historesin. It allows easy orientation for sectioning large areas parallel to the surface. Selected fields can be monitored from the unfixed specimen, throughout preparation, to mounting on the microscope slide. For cross-sectioning, the flat-embedded tissue can be stacked and re-embedded(More)
