Background: Human peripheral blood NK cells constitutively express CD56 and CD16 antigens. Peripheral blood NK cells seem to be strongly related with decidual NK cells, and may reflect the decidual NK cell functional status. There are varied reports concerning the relationship between NK cell cytotoxicity in women with recurrent spontaneous abortion. Objective: To study NK activity in women wit...

conclusions the outcome of this study is that the oca has no toxic effect on h9c2 cells. results the results showed that the percentage of survived cells amount of extract dilution ratio (1:4; 1:2; 1) were 80.4%; 79.6%, 77.5% respectively. analysis of statistical test results does not show any significant differences between the optical density of the extract dilutions, and the control group in...

the current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of eremostachys azerbaijanica (labiatae) as well as analyzed the potent extracts using gc-ms. extracts of e. azerbaijanica in n-hexane, dichloromethane (dcm) and methanol (meoh) were prepared using a soxhlet apparatus. the antioxidant activity of the extrac...

Assessment of the cellular effects of natural and/or synthetic products is one of the major goals in biological experiments. This assessment may be conducted at different levels; cellular viability, cellular biological activity, and cellular structure and morphology. Different assays are available for any of above purposes. It is becoming of a routine exercise to apply any of these assays, and ...

 Background: The use of natural products as anticancer and antioxidant agents has a long history. Several drugs currently used in chemotherapy were isolated from plant species. Objective: The aim of this study was to evaluate cytotoxicity and antioxidant activity as well as phenol and flavonoid contents of five plant species of Solanaceae family. Methods: Five plant species of Solanace...

MTT assay is commonly used to assess the cellular cytotoxicity caused by anticancer drugs in glioblastomas. However, there have been some reports insisting that MTT assay exhibited non-specific intracellular reduction of tetrazolium which led to underestimated results of cytotoxicity. Here, we examine whether or not MTT assay can lead to incorrect information regarding alcohol-induced cytotoxic...

background & objective: chlorhexidine solution is one of the widely used mouth antiseptic liquid that prevents teeth tissue damage and also has application as a root canal antiseptic. in this study, cytotoxicity of 2% chlorhexidine solution is compared with another root canal antiseptic, calcium hydroxide powder. materials and methods: cell cytotoxicity of both chemicals was assessed on culture...

chemical investigation of garcinia eugenifolia and calophyllum enervosum yielded six compounds. one of these was found to be a novel compound identified as enervosanone. five known compounds cambogin, epicatechin, osajaxanthone, rubraxanthone and isocowanol, were also isolated. these compounds were tested for their bioactivity as antimicrobial, antioxidant and cytotoxicagents. antimicrobial ass...

The cytotoxicity of different samples of carbon nanotubes synthesised by catalytic chemical vapour deposition was investigated towards human umbilical vein endothelial cells, using two cytotoxicity standard assays (neutral red assay for the cell viability and MTT assay— tetrazolinium salt—for the cell metabolic activity). No cytotoxicity was found for any sample.

The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...
