a lot of chemicals such as poly (amidoamine) ( pamam - nh2 ) dendrimers have pharmaceutical applications, but the major problem with pamam - nh2 is their cytotoxicity and mutagenicity. in this research, we have investigated the cytotoxicity and mutagenicity of various generations of pamam-nh2 (g2.0, g3.0, g4.0, and g5.0). the cytotoxicity of pamam-nh2 at the dilutions of 0.01, 0.001 and 0.0001(...

Background: One of the important materials needed for root treatment is sealers. They fill space between gutta and canal walls create a suitable seal to prevent colonization oral microorganisms in peri-apical tissues inside space. Aim: The aim this study was prepare test cell biocompatibility new polycaprolactone-based endodontics sealer comparison AH plus against dental pulp stem cells. Method...

A study of lymphocyte cytotoxicity for rabbit hepatocyte cultures in 15 patients with untreated chronic active hepatitis showed positive results in all cases, both HBsAg positive and negative. After immunosuppressive therapy cytotoxicity became negative and remained negative, in four of nine patients followed serially. In 51 patients established on therapy for periods from three months to 12 ye...

Formocresol is common treatment in exposed pulp of primary teeth at caries, trauma and damaged with cavity preparation. Although, clinical and radiographic success and good clinical results are observed, dentistry societies are still searching for materials interchangeable with formocresol. Suab1 is a phytochemical agent that was selected because of its anti- bleeding effect. In this study, we ...

Hypothesis Anthocyanins possess well-known biological effects and suppress DNA damage induced by therapeutic topoisomerase poisons. Our study focusses on the modulatory effects of anthocyanidins-malvidin (MAL) and pelargonidin (PEL)-on topoisomerase II poison mitoxantrone (MXT)-induced cytotoxicity and genotoxicity in in vitro and in vivo conditions. Study design HepG2 cells were treated with M...

This study aims at determining the Minimum Inhibitory Concentration with Escherichia coli ATCC 25922 and cytotoxicity to L929 cells (ATCC CCL-1) of the waste generated by doxycycline degradation by the Fenton process. This process has shown promise in this treatment thanks mainly to the fact that the waste did not show any relevant inhibitory effect on the test organism and no cytotoxicity to L...

In this study, cytotoxicity of various novel poly(alkylpehnol) derivatives which, one of constituent for vulcanizing agent, could be adjusted in medical elastic rubber applications were investigated under various conditions of cytotoxicity test. By MTT-assay which according to ISO 10993-5 regulation, we could figure out cell viability of mouse fibroblast in various sample conditions. Furthermor...

Backgrounds Justicia gendarussa Burm.f. has an anti-HIV activity. This study was conducted to evaluate the effects of incubation periods on the cytotoxicity and virucidal activities of the J. gendarussa leaves extract on MOLT-4 cells. Materials and Methods The cytotoxicity assay was evaluated by using the WST-1 test with incubation periods of 3 days and 5 days. The virucidal activity test was...
