M concentration also gave some protection against MSE toxicity at high dose but not sufficient to be significant when compared to Control groups. D) it appears that naltrindole again successfully inhibited MIT toxicity at all concentrations tested. Whereas for the longer term effects (clonogenicity assay) fig. Kratom Headache kratom extract x30 bloomington Nausea m successfully gave protection against MSE toxicity at all dose range however it was not that effective for MIT at high dose.
For survival studies 24 hour-treated cells (SH-SY5Y and HEK 293 kratom store seattle cells) were trypsinised centrifuged and reseeded at 100 cells per well in 6 well plate for each dose of MSE in 2 ml drug-free medium and incubated for a period of 6-7 days. The wells were stained with methylene blue (1% in 50% methanol) and colonies that contained 50 or more cells were scored as survivors. Relative cell survival was expressed as percentage of appropriate vehicle-treated controls.
ROS generated from mitochondria of SH-SY5Y cells was measured by

fluorescence in which the intensity of fluorescent product DCFH is proportional to the levels of intracellular ROS generated. Results of the preliminary assay as shown in fig. H202 significantly released ROS as soon as it was added to the cells (at the 30
minute time interval) and was consistently higher than other group treatments.
Then the lysates were centrifuged at 10000g for 1 minute and the supernatant (cytosol exract) was collected and kept on ice. B(containing 4% cupric sulphate):A (containing sodium carbonate sodium bicarbonate bicinchoninic acid and sodium tartrate in 0. M sodium hydroxide) (Pierce U.

In addition this study also suggests that metabolism particularly the activation of CYP 2E1 appeared to increase the MSE cytotoxicity thus caution best malaysian kratom experience kratom from iamshaman should be taken as this is likely to occur in vivo if Mitragyna speciosa Korth leaves were to be taken with CYP 2E1 inducers. Prior to this study nothing was known about the cytotoxicity effects of MSE and MIT. Thus this study provides the first information on the toxicological implications of the exposure to MSE and MIT.
