We describe our experience with succinic dehydrogenase inhibition (SDI) test for solid tumors as a chemosensitivity test using 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide. Specimens were obtained from 76 surgical resected tumors, including 32 colon cancers, 24 stomach cancers and
In order to determine the most effective anticancer agents for individual human tumor, succinic dehydrogenase inhibition test (SDI-T) and adenosine triphosphate inhibition assay (ATP-A) as in vitro chemosensitivity tests were performed. Fifty tumors and 57 tumors derived from cancer patients
Succinic dehydrogenase (SDH) was localized in the mitochondria of Sarcoma 37 ascites tumor cells by the use of tetranitro-BT (TNBT) and nitro-BT (NBT) in smear preparations. Results with each tetrazolium salt as electron acceptor were evaluated with respect to: (a) size and shape of the formazan
The activity of a group of respiratory enzymes was studied in normal menopausal as well as benign and malignant tumours. A decrease in the activity of succinic dehydrogenase, diphosphopyridine nucleotide diaphorase and cytochrome oxidase in malignant tumours especially in spindle cell sarcoma and
A test system using dehydrogenase activity for predicting the response to chemotherapeutic agents against cancer cells was introduced. Agar plate assay, INK which test, and SDI test commonly employed in the clinical study were also reviewed. Agar plate assay resembles antibiotic disc sensitivity
This study compares the toxic effects of the carotenoids, beta-carotene and canthaxanthin, and alpha-tocopherol (vitamin E) on human tumor cells and their normal counterparts in vitro. Seven different malignant cell lines were examined: oral carcinoma (two cell lines), breast (two cell lines), lung
Coptidis Rhizoma and Aconiti Kusnezoffii Radix represent hot Chinese medicine and cold Chinese medicine respectively. The purpose of this study is to observe the differentiation effect of Coptidis Rhizoma and Aconiti Kusnezoffii Radix on lewis lung cancer and compare effect of hot Chinese medicine
BACKGROUND
We investigated sequential effects of HIFU ablation combined with contrast agent SonoVue by using histopathology examination, immunohistochemistry, and enzyme histochemistry.
METHODS
Forty rabbits with VX2 liver tumors were subjected to HIFU ablation. Before ablation, a bolus injection of
We investigated the clinical usefulness of individualization of chemotherapeutic regimen in neoadjuvant intra-arterial chemotherapy for locally invasive bladder cancer. Anticancer drugs were selected according to the results of an in vitro chemosensitivity test (collagen matrix assay or succinic
We will report the result obtained from sensitivity tests on various anti-cancer agents for malignant bone and soft-tissue tumors based on SDI (Succinic Dehydrogenase Inhibition Test) method with the use of enzymic activities as marker since 1976. Our study comprised 27 cases altogether 15 cases of
The Succinic Dehydrogenase Inhibition test (SDI test) has been widely used for a long time to evaluate the sensitivities of cancer cells to anticancer agents. Recently, the techniques for tissue culture have progressed and the ability to make formazan improved through the use of MTT in this assay
Glutathione-S-transferase (GST) in one of several factors that are proposed to affect tumor sensitivity to anticancer drugs, including cisplatin (CDDP). Attempts are made herein to evaluate the significance of the enzymes in resistance to CDDP in clinical samples of gastric cancer. A total of 22
The succinic dehydrogenase inhibition (SDI) test has been widely used to evaluate the sensitivity of cancer cells to anticancer agents. Recently, the techniques for tissue culture have progressed; the ability to make formazan has improved with the use of methylthiazol tetrazolium bromide (MTT)
In order to determine the most effective anticancer agent for individual human tumor, we have performed several chemosensitivity tests, such as human tumor clonogenic assay (HTCA), succinic dehydrogenase inhibition test (SDI-T), nude mouse isotope assay (NM-IA) and subrenal capsule assay (SRCA). In
