The main target system of MSE and MIT Prevent Kratom Hangover cytotoxicity is the central nervous system as shown by sensitivity of neuroblastoma cell lines (SH-SY5Y) throughout the studies. Prevent Kratom Hangover in general MSE and to a lesser extent MIT were found to exert their dose dependant cytotoxicity effects in all human cell lines examined both in acute treatment and also in the longer term as assessed by the clonogenicity assay. M arrest for HEK 293 cells.
In parallel caspase inhibitors were employed to confirm the outcome of the former assays. The caspase-8 and caspase-9 colorimetric assays purchased from Invitrogen U. IETD and LEHD respectively.
M CaCl2 at pH 7. The cells were then incubated on ice for 5 minutes until data acquisition with a Becton Dickinson FACSCalibur flow cytometer using CellQuest Pro software. Annexin V conjugate was measured at 650 nm excitation and 665 nm emission and 7-AAD at 488 nm excitation and 620 nm emission.
These current experiments suggest that cell cycle arrest could be an associated event for the toxicity effects seen. In order to assess these effects more fully the well established Modfit software was employed for more detailed cell cycle analysis. In general the DNA profiles for MSE treated MCL-5 cells (Fig. MSE table 2. MSE suggested that 24 hr was the time point at which the changes began to be noted.
Based on the long use of this plant by humans with no reports on serious health effects or cancer formation it might be assumed that the use of this plant is safe. All substances are poisons; there is none that is not a poison. The hypothesis was tested using various in vitro techniques which assessed the cellular and biochemical consequences of exposure.

finding supports the suggestion that there is no overt evidence of cancer or tumour incidence upon consumptions of Mitragyna speciosa Korth leaves. Introduction Cytotoxicity and genotoxicity status of MSE and MIT were established in the previous chapters and both agents were determined to be toxic at high dose but not genotoxic. The molecular events leading to toxicity are yet to be fully understood.

The study also confirmed that there was no involvement of ROS production in MSE and MIT induced cell death implying that mitochondrial integrity is not compromised. Finally evidence from this study also suggested that the opioid receptors are highly involved in mediating MSE and MIT cytotoxicity . Overall the first ever in vitro toxicology assessment of extract of Mitragyna speciosa Korth leaves as used in this study provide information that the consumption of Mitragyna speciosa Prevent Kratom Hangover Korth leaves may pose harmful effects to users if taken in high dose.
The p53 protein level was found to be decreased in a dose-dependant manner especially at lower concentrations of MSE treatment for 24 hr as shown in fig. Further experiments were carried out to kratom on drug test spooner determine the time course of the down regulation or loss of p53 (Fig. MSE and control groups implying that this cell line expresses p53 protein and the lost of p53 protein seen at high doses was due to treatment effects.
M where there was borneo red vein thai kratom evidence for a G1 arrest. The observations on the right shifting of the DNA profiles which was pronounced in the high doses of MSE and MIT in MCL-5 and SH-SY5Y cells has raised question in this study. This phenomenon implies that the live cells have taken up more PI thus increasing the DNA staining intensity. At this stage the possible explanation for this phenomenon is unknown however; it could be due to the plasma membrane integrity being compromised due the treatment effects thus creating maeng da kratom dose pores or increase kratom drug test kit wood lake membrane permeabilisation. Numerous studies have shown that wild-type p53 can restrain cell cycle progression and induce cell death via apoptosis when the cell is irreversibly damage (Sugrue et al 1997). WAF 1 is a p53 target gene and both are well known to have positive correlation with cell cycle arrest (Morgan 2007; Prevent Kratom Hangover Harper et al 1993).
Briefly the slides were fixed with absolute methanol for three minutes followed by immersion in Wright-Giemsa stain for 1 minute rinsed in PBS for 1 minute and finally in water for 1 minute. The slides were mounted with DPX and were examined using Zeiss Axiovert 200 widefield microscope at 1000x magnification. For MCL-5 cells after designated incubation period the treated cells were transferred into a centrifuge tube followed by centrifugation (1000 rpm for 5 minute).
These assays were carried how to use kratom powder extract out according to manufacturer instructions. MSE for 4 hr and 24 hr incubation time points. After incubation the cells were harvested by routine trypsinisation procedure as described in chapter 2 section Prevent Kratom Hangover 2.
Apart from the effects of using this plant seen with traditional users and drug addicts as described previously in chapter 1(section 1. With the introduction of legislation against possession of this plant in Malaysia the access of this plant to the public Prevent Kratom Hangover especially to drug addicts is now under tighter control. Like many other traditional remedies that exist in the market the potential toxicity of this plant and its derivatives are not fully known.
