Thus this information poses the question of whether the opioid receptors mediating the biological activity of the Mitragyna speciosa Korth plant may also mediate the MSE and MIT induced toxicity or cell
death. I therefore predicted that opiate receptor antagonists would protect against MSE and MIT induced cell death. MSE toxicity both in acute and longer term treatment.

The effect of MSE for 24 and 48 hr time period (Fig. M phase cells was noted for all doses compared to control cells for the first 24 hr treatment period. However there were no apparent DNA profile changes seen for the 48 hr treatment group.
After 30 minutes cells in each well were treated with H202 MSE and MIT and the fluorescent readings were continually read at 10 min intervals for up to 1 hr period. This preliminary assay was performed to establish the working conditions for the assay. As described earlier the cultured medium was aspirated and fresh PBS (1 ml) was added to each well. M) was then added to the wells under subdued lighting and NAC was also added to appropriate wells. C (5% CO2) for 30 minutes. As the addition of DCFH-DA dye led to precipitation as seen in the preliminary experiment after 30 min the cultured solutions were aspirated and fresh PBS (1 ml) was added to each well prior to adding the test compounds (H202 MSE and MIT).
SH-SY5Y cells which are known to have wild-type p53 have constitutive expression of p53 in the control and lower doses groups. The loss of p53 protein was noted as early as 6 hr after MSE treatment. A similar finding was also observed for p21 protein. P21 is one of the main target genes for p53 and both p53 and p21 are well known to have a positive correlation in assisting the cycle arrest by inhibiting the cyclinCdks complex formation (Morgan 2007). Based on these observations two possibilities are considered: 1) the effect is cell cycle arrest independent of p53 and p21 pathway or 2) the loss of these proteins could be due to the leakage due to the increased membrane permeability or through pore opening.
The results for MIT as shown in table 3. A and 3. B also revealed a negative outcome for genotoxicity under conditions with or without the presence of metabolic activation by S9. In this case the metabolic activation by S9 did kratom 40x extract not activate the toxic effects of MIT which was contrary to what we had seen for MSE.
M human consumption of Mitragyna speciosa Korth leaves at pharmacologically active doses would appear to be substantially lower than the threshold of toxicity predicted from my in vitro study. Taking into account all the findings of my studies MSE and MIT could be potentially harmful in humans at high doses. The safety assessment assumptions suggest that the use of Mitragyna speciosa super malay kratom review Korth leaves within the range of pharmacologically active doses as reported in the literature is probably safe however caution should be taken as MSE toxicity in this study was found to be enhanced by metabolism particularly by CYP 2E1.
