Histology of the tumor and cytology of the MPE from mice in the control group. Apparent malignant pleural effusions can be seen in the cavity of mice treated with H-β-C (A). Following staining with hematoxylin and eosin, the slice indicated that pleural tumors consisted of adenocarcinoma cells (B), and the tumor had broken the visceral pleura. A representative photomicrograph of a cytospin from a malignant pleural effusion stained with modified Wright’s-Giemsa stain shows LLC cells with large nuclei and visible nucleoli (C). LLC, Lewis lung carcinoma; H-β-C, hydroxypropyl-β-cyclodextrin.
