Since in my present study the apoptotic-like cell death induced by MSE was suggested to be caspasesindependent an investigation looking at generation of ROS in mediating the apoptotic events was carried out. Unfortunately the results in my study showed that there was no ROS generation upon treatment with high doses of MSE or MIT. During the ROS study another interesting observation was made specifically that MSE co-treatment with NAC appeared to protect the cells from death and that chemicals present in the MSE emphasised this effect. Tsuchiya et al 2002; Thongpradichote et al 1998; Tohda et al 1997).
For cytological examinations Rapi-Diff staining was purchased from Bios Europe U. Wright-Giemsa staining was from Sigma-Aldrich U. The opioid receptor antagonists naloxone naltrindole and cyprodime hydrobromide were purchased from Sigma-Aldrich U. IV set was from Calbiochem U. Caspase -8 and Caspase-9 Protease Kits were from Invitrogen U. The fluorescent dye 27-dichlorofluorescein diacetate (DCFH-DA) and hydrogen peroxide (H202) for ROS assay were purchased from Sigma-Aldrich U. Cytological examination of MSE treated cells Cytological examinations were carried out using SH-SY5Y HEK 293 and MCL-5 cells.
M human consumption of kratom uei tea 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 Korth leaves within the range of pharmacologically active doses as reported in the literature is kratom capsules illegal probably safe however caution should be taken as MSE toxicity in this study was found to be enhanced by metabolism particularly by CYP 2E1.
This finding supports the cytological examinations previously noted where the cells were predominantly necrotic and in the late stage of apoptosis. Control 1 10

Ten thousand cells were analysed by CellQuest Pro software and the subG1 population representing apoptotic cells were gated manually. Reactive oxygen species (ROS) analysis in SH-SY5Y cells treated with MSE and MIT ROS generation assay was carried out using SH-SY5Y cells by using a fluorescent dye 27-dichlorofluorescein diacetate (DCFH-DA). Principally this dye diffuses through the cell membrane and is hydrolysed enzymatically by intracellular esterases to form monofluorescent dichlorofluorescein (DCFH) in the presence of ROS.
Finally the slides were rinsed briefly in the buffered water (pH 7. The slides were mounted with DPX and microscopic examination was then carried out similarly as described for WrightGiemsa staining procedure. AAD double staining for apoptosis detection In principle the cell membrane of live cells is covered by phospholipids (lipid bilayer) in which phosphatidylserine is located on the inner layer of the plasma membrane. In early Kratom Extract Full Spectrum stages of apoptosis the phosphatidylserine is exposed to the outer surface of the plasma membrane (Darynkiewicz et al 2001; Fadok et al 1992). Darynkiewicz et al 2001; van Engeland et al 1998). C (5% CO2) for 24 hour.
In principle in DNA cycle analysis the movement of DNA profiles to the right side of the scale indicates more dye has been taken up. This would be the implication if the pores of the plasma membrane open or if there was a mechanism in which the dyes could diffuse more easily into the cell. Another flow cytometry analysis was carried out in this chapter this time using double staining with Annexin V conjugates-7-AAD to further determine the nature of cell death.

The limited amount of MIT available to me throughout the studies have restricted the testing of MIT in parallel with all MSE assessments. This limitation has compromised a comprehensive investigation on MIT induced cytotoxicity and cell death. It is therefore important for future in vitro investigations to look for morphological assessment of MIT induced cell death and further confirmation on the involvement of initiator caspases 8 and 9 to support the current findings.

NO loss of potency whatsoever. I am always up for learning if there is anything to be learned. I have been combining my much needed and legally prescribed amphetamine prescription with kratom for some time. I premium bali kratom powder had been using kratom for years prior.
