The cell pellets obtained were re-suspended in 1 ml cold PBS or D-PBS. Cell counting for each cell type was performed and 2 x 104 cells were transferred onto microscopic slides followed by centrifugation (cytospin at 450 rpm for 5 minute). The slides were then air-dried for 10 minutes and Easy Kratom Tea Recipe is kratom illegal in ky palmer stained with Wright-Giemsa kratom extract gnc north ferrisburg staining.
MIT sample was also prepared as MSE however did not undergo centrifugation process. The cells were then maintained in serum free media for 24 hr. Enough pressure was applied to completely cut through the layers of cells.
The results from different cell lines used in the viability studies demonstrated that the human neuronal SH-SY5Y cell was the most sensitive cell line examined. The IC50 following 24 hr treatment of SHSY5Y cells were 91. MSE and MIT respectively.
There were no significant differences in the kratom opiate maintenance subG1 population (apoptosis population) between treated groups (caspase 3 inhibitor caspase 8 inhibitor caspase 9 inhibitor and general caspase inhibitor treated with high dose of MSE) and the control and negative control groups. At this stage it seems that despite having high MIT content in the MSE the high dose MSE treatment in SH-SY5Y cells does not activate caspase enzymes. This probably could be due to other chemicals that present in MSE preventing the activation of thai kratom powder tea caspase enzymes. Cell death of SH-SY5Y cells after MSE and MIT appeared to be predominantly via apoptosis based on its morphological appearance however biochemically the results discussed above fail to support a caspase mediating event.

Thus it is suggested that apart from MIT there are other chemicals present in the leaves of Mitragyna specioa Korth contributing to the MSE cytotoxicity. A summary of the cytotoxic events leading to MSE or MIT induced SH-SY5Y cell death as discussed above are shown in fig. Mechanisms of MSE and MIT induced SH-SY5Y cells arrest and cell death.
This phenomenon was noted to be parallel to the cell cycle arrest and the right shifting of the DNA profile in the cell cycle analysis. These events only occurred at high doses of MSE or MIT. SH-SY5Y cells which are known to have wild-type p53 have constitutive expression of p53 in the control and lower doses groups.

However the Thai government has banned the use of kratom and classed the plant as a drug in the same category as cocaine and heroin. Consequently kratom has the dubious honour of being banned in the country it originated in and where it had been used traditionally for centuries. The Mitragyna genus part of the family what is captain kratom thai capsules Rubiaceae is found in tropical and sub-tropical post kratom depression regions of Asia and Africa. Kratom Maeng Da. Kra Thum Khok. Sakae Naa (Combretum. Hallea) are often found in swamps.
The preliminary data on selection of dose range and final summary of the MLA results for the MSE and MIT are discussed below: 3. MLA for MSE As shown in table 3. This implies that the presence of S9 at these concentrations increase the metabolic activation of MSE to toxic derivatives which killed the majority of the cells. However as shown by MSE treated groups in the absence of S9 MSE even at highest dose administered did not show any toxic effects. MSE were omitted from plating as their RSG value were nearly similar to the negative control groups.
Culture medium background) The total number of cells in each assay well was assessed using the proliferation assay protocol. In order to estimate the percentage of dead cells after treatment with MSE or MIT cells were harvested by centrifugation and with trypsinisation for adherent cells. The cells were then stained with trypan blue solution (0. For survival studies 24 hour-treated cells (SH-SY5Y and HEK 293 cells) were trypsinised centrifuged and reseeded at 100 cells per well in 6 well plate for each dose of MSE in 2 ml drug-free medium and incubated for a period of 6-7 days. The wells were stained with methylene blue (1% in 50% methanol) and colonies that contained 50 or more cells were scored as survivors. Relative cell survival was expressed as percentage of appropriate vehicle-treated controls.
