Dose dependant lost of p53 and p21 observed at the same concentrations causing cell cycle arrest remains unexplained. The data also suggested that the cell membrane integrity was compromised leading to the loss of cell content possibly through membrane opening or increased membrane permeability. In this chapter kratom high tolerance further investigation was attempted to explain these observations and to examine the mode of cell death of the cells treated with MSE and MIT. Non Opiate Pain Medication in general the two distinct pathways of cell death are via apoptosis or necrosis which are distinguishable morphologically and biochemically (Majno and Joris 1995; Wyllie et al 1980). The term of apoptosis was first coined by Kerr et al (1972) and it was described as an active way of killing the cells and organising its disposal which was easily detected under a microscope as cells undergo condensation of nuclear chromatin followed by formation of blebbing and segregation of the nucleus into fragments known as apoptotic bodies and finally disposed of by digestion via lysosomal pathway (Kerr et al 1972).
This finding is consistent with the result of the previous flow cytometry analysis with PI staining performed in chapter 4 section 4. For MIT treated cells changes of the four populations were not as drastic as MSE treated cells. Q3 and Q4 indicating increased of apoptotic and necrotic cells. For MCL-5 cells (Fig 5. The majority of the cells were evidently located in the Q3 and Q4 indicating the necrotic and late stage of apoptotic populations. This finding supports the cytological examinations previously noted where the cells were predominantly necrotic and in the late stage of apoptosis.
Apart kratom bluelight from the acute cytotoxicity effects seen in different cell lines another major finding in this part of the study was the longer term cytotoxicity effects as determined by colony forming ability will kratom how to stop opiate withdrawal (clonogenicity assay). The concentration of MSE required to reduce the ability of the cells to form colonies was seen to be five times higher compared to results obtained in acute viability assay (trypan blue exclusion). This suggests that the uptake of dye (trypan blue) into the cells does not reflect the actual outcome of the cells in the longer term.

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 super premium indonesian kratom effects 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 kratom where to buy in canada doses.

It was believed to be due to the
incomplete removal of chloroform during the preparation of MSE. With this finding a concern arises whether this minor contamination would affect the toxicity of MSE or MIT (from Japan) in the cell based studies. We therefore chose to use spiking experiments where chloroform was added to MSE at known concentrations and the effect of the mixture on cell toxicity was determined. The clonogenicity experiments using SH-SY5Y cells indicated that the chloroform contamination did not pose any obvious cytotoxic effects to level up of 500 uM concentrations which is far beyond that expectated to be in the MSE. M chloroform with MSE effects alone or chloroform alone (these data are from collaboration experiments with Thomas Randall ICL).
Based on the validation criteria for MLA as described in the section 3. Mean Control MF (77. GEF (126 x 10-6).
Although to date there is no report of cancer associated with consuming the leaves of this plant a genotoxic assessment such as mutagenicity aids prediction of carcinogenicity potential. Thus for the first time I have shown that genotoxicity Non Opiate Pain Medication testing using the mouse lymphoma tk gene mutation assay (MLA) suggests that MSE and MIT have no genotoxic potential. This MSE toxicity was similar to that noted for MSE with the human cell lines (SH-SY5Y and HEK 293 cells) in the presence of S9.
