The percentage of subG1 population unfortunately was not determined during the analysis and the evaluation of this population was qualitative. MSE for 48 hr time period (Fig. MSE the cells in the G1 phase appeared to decrease but the overall profile was considerably altered.

The intensity of the fluorescence is therefore proportional to the levels of intracellular ROS (Galvano et al 2002). A fluorescence-based method to measure ROS generation in live cells was a modification of the procedure described by Esposti and McLennan (1998). This is to ensure that the free-radical quencher albumin present in the serum used as a media supplement is removed as it interferes with the quantitative analysis of ROS (Esposti 2002).
Other pathways may be considered for MSE induced cell death with no involvement of caspase activation but yet kratom dosage maeng da following the programmed fashion. Involvement
of several enzymes from lysosomal pathways such cathepsins How Long Does Kratom Show Up On A Drug Test and calpains were shown to highly correlate to apoptotic-like or even necrotic cell death (Jiang et al 2006; Yamashita et al 2003). Mitochondria which play a key role in the intrinsic pathway for apoptosis may also again be involved as apoptotic inducing factor (AIF) which is usually released after activation of Bcl-2 family acted with the EndoG protein released from plasma membrane to trigger kratom illegal for military apoptotic-like cell death ( Jiang et al 2001). Many agents are currently known to induce cell death via caspase independent pathways as described above such as campothecin doxorubicin and paclitaxel. The necrotic type of cell death induced by MSE which is morphologically seen in cell lines such as MCL-5 and HEK 293 cells could not be confirmed biochemically due to time limitations. Unlike MSE MIT treated SH-SY5Y cells have shown a different mechanism of cell death in which there was an involvement of caspases 3 and 7.
Prior to this study MIT was thought to be the compound responsible for the narcotic effects of this plant. In the early part of this study basic in vitro toxicology revealed that MSE and MIT have dose dependant toxicity to several human cell lines and the SH-SY5Y cell was the most sensitive. This is not surprising as the central nervous system was pharmacologically determined as the target system for the biological effects of this plant thus a kratom opioid addiction toxicity response might be anticipated in neuronal cells.

A standard curve for MIT was generated (Fig. The absorbance reading for each MSE fraction at 227 nm wavelength was recorded. Using the equation derived from the MIT standard curve an estimation of MIT present in each MSE fraction was calculated (refer to Appendix 1 for details of calculations). Based on this calculation it was estimated that MSE contained approximately 42% MIT-like compound. Absorbance 227 nm 2 1.

In order to examine the in vitro toxicity of MSE the effect of the mixture on HepG2 cells was examined. Homogenous Membrane Integrity Assay.
