In the previous section it was noted that there were no major differences in p53 band intensity over the dose range tested compared to the control group implying that MIT does not induce the loss of protein as seen in the MSE treated cells. As with the p53 effects noted previously MIT had little effect on p21 levels (Fig. P21 levels of MSE treated SH-SY5Y cells at different time points (6 12 24 and 48 hr).
As anticipated the experiments clearly showed that p53 was still being expressed in MIT treated groups and in control group but down regulated with time- dependant manner. Kratom Smoke Blends m) the same pattern of p53 down regulations was seen as with the higher dose of MSE. The next experiment was carried out to further investigate if there was a correlation between p53 changes and its target gene p21 in response to MSE and MIT treatment.

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 Kratom Smoke Blends 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.
Thus the combination consumption dea kratom 2015 of Mitragyna speciosa Korth leaves with CYP 2E1 inducers may shift toxicity closer to doses that are pharmacologically active. Based on the current findings observed in the present studies it is concluded that the methanol-chloroform extract (MSE) of the Mitragyna speciosa kratom like adderall collinston Korth (Kratom) leaves and its dominant alkaloid mitragynine (MIT) have potential to cause cytotoxicity to
mammalian cells at high doses and is possibly harmful to human users. MIT is proposed to be a major contributor to MSE cytotoxicity. The main target system of MSE and MIT cytotoxicity is the central nervous system as shown by sensitivity of neuroblastoma cell lines (SH-SY5Y) throughout the studies. 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.

K) the assay was accepted based on the measurement of cytotoxicity by relative total growth (RTG) which reduced to approximately 10-20% when compared to concurrent vehicle control. The mean vehicle control value for mutant frequency (MF) are between 50-170 x 10-6 The mean cloning efficiency is between 65-120%. The mean suspension growth are between 8-32 on day 2 (following 3 hr treatment with S9) After exclusion of obvious outliers at least 2 acceptable vehicle controls cultures remain.
This was due to the measured RSG value being very low (18. A) which therefore affected the final calculation for the RTG. Preliminary data of MIT treated groups with and without the presence of S9. C MIT Treatment with S9 (3 hr) 30 20 10 5 DMBA Neg.
Cells treated with both high concentrations of MSE (Fig. A) and cells pre-treated with NAC appeared similar to Kratom Smoke Blends Control group. This infers that MSE did not generate ROS which confirmed the earlier finding.

The stimulation effects claimed at low doses are based on anecdotal reports from users however the specific clinical pharmacology and controlled dosage for humans is still poorly understood. One of the main reasons for conducting toxicology studies is to determine the risk or in other words to determine the potential for harm towards human health or the environment upon exposure to naturally occurring or synthetic agents. Thus the findings of this study will hopefully contribute to a better understanding in predicting the risk upon consuming Mitragyna speciosa Korth leaves. M human consumption of 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 probably safe however caution should be taken as MSE toxicity in this study was found to be enhanced by metabolism particularly by CYP 2E1.
