Cells treated with both high concentrations of MSE (Fig. A) and cells pre-treated with NAC appeared similar to Control group. Kratom Types Comparison Inkster this infers that MSE did not generate ROS which confirmed the earlier finding.

On this basis it was assumed that the positive effect was due to the excessive cytotoxicity in Kratom Types Comparison Inkster line with the ICH S2A guidelines (1995) and the result is considered invalid. The other concentrations tested were negative for genotoxic potential. The presence of S9 appeared to have a substantial effect on the RTG with MSE. In fact there was a clear dose-dependant what is kratom green xl toxicity observed suggesting that the MSE was being activated to a toxic derivatives. MSE in the absence of metabolic activation with S9 did not produce evidence of genotoxicity (Table 3.
A in the previous chapter (section 2. MSE in the presence of S9 reduced the colony formation to less than 10% of the vehicle treated control. A similar outcome was seen using S9 with L5178Y cells in this assay in the preliminary tests for selecting the range of concentrations performed prior to plating assessment.

Based on UV-VIS spectrometer analysis MSE extract obtained by this method was estimated to contain approximately 42% of MIT-like compound. Since the percentage of MIT present in the MSE is high MIT was assumed to be the major contributor for the MSE Kratom Types Comparison Inkster effects.However it should be born in mind that the methanol-chloroform extract of Mitragyna speciosa Korth used in indonesian white vein kratom the current study (MSE) was prepared to maximise the MIT-like chemical content of kratom alcohol effects the extract and is probably not bioequivalent to aqueous extract that humans are exposed to as kratom high opiate the result of chewing leaves.
Arrows ( MSE; MIT) represent actual events occur in this study which leads to cell death. Dotted arrows ( MSE; MIT) represent possible mechanism of cell death as discussed in the text. The cell cycle arrest by MIT insult was associated with a positive link between p53 and p21; however cell cycle arrest due to MSE insult remains unclear due to loss of p53 and p21.
