MIT toxicity was not possible. Introduction The results from trypan
blue exclusion mitragyna speciosa korth plant experiments and clonogenicity assays described in the previous chapter (chapter 2) demonstrated that MSE and MIT were cytotoxic in the cell lines examined. Does Kratom Help With Benzo Withdrawal Mayer whether the cell death was accompanied by DNA damage was unknown.
After washing the membrane was incubated in appropriate primary antibody prepared in blocking solution (refer to table 4. C) on the tilt table overnight. The membrane was washed again with PBST three times for 10 minutes duration each time and the appropriate secondary antibody (horseradish peroxidase conjugated) was added and further incubated in room temperature on the tilt table for 1 hour duration (refer to table 4.
Therefore it was assumed that the minor contamination of chloroform in both MSE and MIT was not contributing to the toxicity. We observed that MSE exerted dose dependent cytotoxicity with several human cancer cells both via trypan blue exclusion assay and clonogenicity assay. Most xenobiotics undergo metabolic activation
in the process of exerting their cytotoxicity effects. Cytochrome P450 oxidative enzymes are key enzymes involved in this xenobiotic metabolism. To the best of my knowledge apart from biotransformation of MIT in the fungus helminthosporum sp. MSE or MIT. A2 2A6 2E1 3A4 and human epoxide hydrolase) and cHol cells (lack of metabolic activity).

Another flow cytometry analysis was carried out in this chapter this time using Does Kratom Help With Benzo Withdrawal Mayer double staining with Annexin V conjugates-7-AAD to further Does Kratom Help With Benzo Withdrawal Mayer determine the nature of cell death. Surprisingly this time a similar outcome was observed for both SH-SY5Y and MCL-5 cells and the shifting of the whole populations was evident at much lower concentrations of MSE than in the previous PI staining in chapter 2. This Does Kratom Help With Benzo Withdrawal Mayer phenomenon is obviously due to the treatment effects as the control and lowest concentration of the MSE tested as seen in fig. The hypothesis of plasma membrane opening is supported with this finding.

The effect of several concentrations of MSE was compared at two times 24 and 48 hr. MSE with concomitant increased subG1 population especially after 48 hr treatment. The subG1 phase is proposed to be an apoptotic population (Darzynkiewicz et al 1992) as cells with condensed DNA appeared to stain less with PI and will appear to the left of the G1 peak. MSE due to substantial toxicity effects even at 24 hr time point. This finding has positive correlations with the result from the trypan blue experiment from chapter 2 (Fig 2. These current experiments suggest that cell cycle arrest could be an associated event for the toxicity effects seen.

Now at the molecular level we are finally beginning to witness the emergence of entirely new chemical structures as we diligently struggle to discover the exciting new applications they have to offer. That is a world were education and kratom legal status japan professionalism reign supreme. Critics say it is more jittery than other Premium Thai strains and argue it is not as long lasting. The active dose is 1-2 grams. High quality Maeng Da is very green in color.
However due to its narcotism properties it has been misused by drug addicts as an alternative to opium or to moderate the withdrawal symptoms of opium. After years of research with this plant mainly using crude alkaloid extracts its dominant alkaloid mitragynine (MIT) and congeners their analgesic properties have been confirmed in vitro and in vivo. This medicinal property has so far been reported in the leaves of this plant but not from other species of Mitragyna. Several countries like Thailand Myammar Malaysia and recently Australia have made this plant illegal due to its narcotism properties whereas in other parts of the world the plant regardless of any indonesian ban on kratom form has been sold widely over the internet. Western culture is increasing and some individuals are now taking it for self-treatment in chronic pain and as an aid to opioid withdrawal (Boyer 2007).
The cell arrest occurring at high doses of MIT was found to be correlated with p53 and p21 expression although the expression changes were marginal compared to control and lower dose groups. The mechanism for cell cycle arrest in the cells treated with high doses of MSE remains unclear as there was no correlation with p53 and p21 as both proteins were lost after the treatment. The level of MSE toxicity for SH-SY5Y and HEK 293 cells was found to be increased 10-fold when metabolic activation system (post mitochondrial rat liver S9 induced with Arochlor 1254) was added to the treatment. This implies that MSE cytotoxicity requires metabolism for its activation and CYP2E1 was thought to be involved in this metabolic activation.
