Salmonella typhimurium (Ames et al 1972). Principally this test employed bacterial strains of S. Therefore only bacteria mutated to histidine independence may continue to grow and form colonies.

mitragynine (MG) a major indole alkaloid found in Mitragyna speciosa (MS) can exert its antinociceptive effects through the opioids system. In the present study the action of MG was investigated as the antinociceptive agent acting on Cannabinoid receptor type 1 (CB1) and effects on the opioids receptor.

Hol cells (human lymphoblastoid) cells without metabolic activities (metabolically non-competent) were from tissue culture stock of the Unit of Molecular Toxicology Department of Biomolecular Medicine Faculty of Medicine Imperial College London. Magee Department of Molecular and Cellular Medicine Division of National Heart and Lung Institute Faculty Medicine Imperial College London. SH-SY5Y (Human neuroblastoma cells) was a kind donation of Dr.

The cell cycle can be defined as a highly regulated series of events that leads to eukaryotic cell reproduction (Morgan 2007). Studies of the cell cycle began as early as the mid-nineteenth century when there was the discovery of cell division. Pioneering work by Wilson (1925) placed the cell cycle with a firm role in the growth development and heredity of living organisms (Nurse 2000). During this phase DNA is synthesised from the original DNA template (replication origins) to yield two DNA strands and duplication of chromosomes (sister chromatids) which involves protein synthesis buy kratom xtreme and packaging of the DNA into chromosomes. M phase) involves two important events the nuclear division (mitosis) and cell division (cytokinesis). M phase to another.

The assessment of p53 levels and its target gene p21 which are highly associated with apoptotic cell death can also be investigated using many in vitro approach bali kratom opiate such as immunoblotting Is Kratom Safe While Pregnant Lehigh (Western blot) kratom high seattle fluorescence image cytometry etc (Mckenzie et al 1999). The generation of ROS in mediating the cell death should also be a major concern in investigating the in vitro assessment of cell death as ROS is a major indicator for mitochondrial dysfunction which in turn could activate many forms of programmed cell death (Tan et al 1998) and a common method to measure the ROS generation in live cells is using the 27-dichlorofluorescein dye (DCFH) (Esposti 2002). Justification Objectives and Hypothesis 1.

Friedberg et al 2006). Cytochrome P-450 enzymes are those most frequently involved in activating genotoxic chemicals; others include microsomal and cytoplasmic glutathione-s transferases sulfotransferases methylating enzymes etc ( Anders and Dekant 1994). DNA damage can also occur in the form of strand breaks either single strand breaks which involved only one DNA strand or double strand breaks in which both double helix strands are severed. The latter is the more hazardous as it can lead to genome rearrangement. Topoisomerase inhibitor compounds such as camptothecin and etoposide are the well known chemicals which cause strand break formation. Bacterial toxin for instance cytolethal distending toxin (CDT) produced by human E.

Bars are SEM. ANOVA with Dunnet post test. IC50 values (Inhibition concentration that caused 50% cell death) of 24 hr treatment with MSE and MIT treated cell lines.

P53 activation may cause apoptosis or cell arrest whereas the hyperactivation of PARP may cause necrosis. Zong and Thompson 2006; Waring 2005). Other proteases also could trigger apoptosis such as calpains and cathepsins which were already discussed in section 1. As mentioned previously necrotic cell death may cause a subsequent inflammation process. A lack of signalling during necrosis may prevent phagocyte recruitment to clean up the cell debris. Numerous studies have indicated that the subsequent inflammation event in necrotic cell death is due to the release of chromatin protein called high mobility group 1 (HMGB1) which leaks rapidly when membrane integrity is lost and which becomes a potent Is Kratom Safe While Pregnant Lehigh mediator for the inflammatory process ( Scaffidi et al 2002; Andersson et al 2000).
