Combining drugs is usually a bad idea. It is recommended that you do not combine kratom with yohimbine cocaine amphetamine-like drugs or large doses of caffeine because of the possibility of over-stimulation or increased blood pressure. MAO inhibitors such as Syrian Rue (Peganum harmala) Banisteriopsis caapi Passionflower (Passiflora incarnata) and certain anti-depressants.
Furthermore the cell cycle protein analysis (p53 and p21) performed using immunoblotting approach indicates the loss of these proteins at high doses of MSE and to the lesser extent MIT. The mechanism of this phenomenon is not obvious. However one hypothesis that could be proposed is the possibility of the membrane integrity being compromised especially at high dose of treatment or in other words the lost of cell content through membrane opening. 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 maeng da enhanced kratom staining with Annexin V conjugates-7-AAD to further determine the nature of cell death.
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. The control and low dose groups however did express p21 protein consistent with the p53 expression. In the parallel experiment with MIT again p21 was expressed in a time-dependant manner that correlated with p53 expression. MIT exerts weaker toxicity effects compared to MSE.
M MIT indicating the loss of p53 protein over time. The findings described above suggest that the cell cycle arrest of MSE treated cells seen previously with flow cytometry was independent of p53 protein induction and to the lesser extent for MIT treated cells. P53 levels of MSE treated SH-SY5Y cells after 24 hr treatment. Bars are the mean of three experiments with SEM.

In this study SH-SY5Y cell death induced by MSE Buy Kratom In Dallas Tx appeared to be independent of p53 and p21 pathway. However the morphological features indicated apoptoticlike type of cell death. Based on these findings it was postulated that Buy Kratom In Dallas Tx the mechanism of cell death of SH-SY5Y cells upon MSE treatment may not follow the common intrinsic pathway which requires the activation of tumour suppressor protein p53.

As anticipated toxicity effects seen at high doses suggested apoptotic morphology with evidence of chromatin condensation which was predominantly xscape kratom dosage seen in SH-SY5Y cells. Nuclear alterations are key in many descriptions of apoptosis. The severity of MSE insult in the SH-SY5Y cell line was obvious at the highest dose tested as there were very few cells present on the slide and all of them showed apoptotic morphology.
The cell pellets were then prepared for flow cytometry analysis using PI staining as described in chapter 4 section 4. The cells stained with PI were analysed using BD FacsCalibur flow cytometer. PI was excited at 488 nm and 620 nm emissions. 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.
