tannic acid/sarcoma

Electron microscopic observation of alveolar soft part sarcoma reveals crystalline structure as well as granules that are only partially composed of crystalloids. The uncrystallized part has been observed only as a dense amorphous substance by the conventional fixation method with glutaraldehyde or

This study aims to obtain mesocarp films of Orbignya sp. (MB) and carboxymethylcellulose (CMC) for application as a drug release matrix. Tannic acid (TA) was used as a standard drug. The films were evaluated by infrared, swelling power, TA release profile, bioactivity and in vitro cytotoxicity.

The immunohistochemical expression of cytoskeletal proteins in alveolar soft part sarcoma (ASPS) was studied by light and electron microscopy. Of the five cases examined by the avidinbiotin-peroxidase complex method, variable numbers of immunoreactive cells for desmin were found in three, for

To facilitate the survey of actomyosin-containing cells in soft tissue sarcomas with skeletal muscle differentiation, the tannic acid-phosphomolybdic acid-Levanol fast cyanine 5RN procedure was applied to plastic-free (deresined) thick sections (2-3 microns) obtained from epoxy blocks conventially

An acidic pine cone extract, Fr. V. of Pinus parviflora Sieb. et Zucc. significantly stimulated DNA synthesis of isolated splenocytes from both mice and rats, but only marginally affected the DNA synthesis of leukemic cell lines. The maximum stimulation level attained by Fr. V slightly exceeded that

The development of tumor drug resistance is one of the biggest obstacles on the way to achieve a favorable outcome of chemotherapy. Among various strategies that have been explored to overcome drug resistance, the combination of current chemotherapy with plant polyphenols as a chemosensitizer has
