Prior to this study most of the investigations on the biological effects of this plant such as antinociceptives effects were mostly comparisons with opiate drugs such as morphine and its related compounds. Thus an important issue is whether MSE or MIT induced cell
death may share similar mechanisms as opiate induced cell death. In general opioids have been shown to induce in vitro apoptosis in cell lines including neuronal cells (Mao et al 2002). The recent review by Zhang et al (2008) stated that morphine for instance induces neurotoxicity and apoptosis after chronic use and heroin also induced apoptotic cell death via mitochondrial malfunction caspase activation leading to PARP cleavage and DNA fragmentation.

This finding supports the suggestion that there is no overt evidence of cancer or tumour incidence upon consumptions of Mitragyna speciosa Korth leaves. Introduction kratom tea euphoria Cytotoxicity and genotoxicity status of MSE and MIT were established in the previous chapters and both agents were determined to be toxic at high dose but not genotoxic. The molecular events leading to toxicity are yet to be fully understood.

As anticipated there was no activation of caspases 3 and 7 activities in cells treated with high dose of MSE at both 4 hr and 18 hr incubation time points. Interestingly for MIT there was a clear significant difference of caspases 3 and 7 activities at both concentrations of MIT tested. This finding suggests that the mode of the cell death of MIT treated cells is dependant

on caspase 3 and 7 activation pathway. There were no significant differences in the subG1 population (apoptosis population) between treated groups (caspase 3 inhibitor caspase 8 inhibitor caspase 9 inhibitor and general caspase inhibitor treated with high dose of MSE) and the control and negative control groups.
Increasing subG1 phase was noted for all dose ranges tested at 48 hr treatment period indicating an increase of the toxicity over time. The subG1 phase has been proposed to be a population of apoptotic cells (Darzynkiewicz et al 1992). Effects of MSE on cell cycle distribution of HEK 293 cells after 24 and 48 hours of treatment. Histograms are representative of three replicates of Kratom White Grapefruit experiments with similar results and analysed by Cellquest Pro software. Values of each phase of the cell cycle were the mean of the three experiments with SEM.
