Cells pre-treated with anti-oxidant NAC produced lower ROS levels than cells treated with H202 alone. Cells treated with both high concentrations of MSE (Fig. kratom thai super zumbrota Premium Kratom Leaf Blue Mountain La a) and cells pre-treated with NAC appeared similar to Control group. This infers that MSE did not generate ROS which confirmed the earlier finding.

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 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) malaysian kratom characteristics huron in the presence of S9. This finding again strongly supported the suggestion that MSE toxicity requires metabolic activation.
In the present study a possible involvement of caspase proteases both pro-apoptotic caspases (caspase 8 and 9) and executor caspases (caspase 3 and 7) were examined using commercially available kits as described in section 5. Possible involvement of pro-apoptotic caspases (8 and 9) The caspase 8 colorimetric assay performed on SH-SY5Y cell lysates indicated little difference between all MSE treated groups and control group for 15x kratom pills both 4 hr and 24 hr incubation time period (Fig. A and B).

Cell lines HEK 293 MCL-5 and SH-SY5Y cells were used. These cell lines were cultured and maintained as described in chapter 2 section 2. Annexin V conjugate staining kit Premium Kratom Leaf Blue Mountain La 7-Amino-actinomycin D (7-AAD) dye and HEPES buffer were obtained from Invitrogen U.

Prior to this study MIT was thought to be the compound responsible for the narcotic effects of this plant. In the early part of this study basic in vitro toxicology revealed that MSE and MIT have dose dependant toxicity to several human cell lines and the SH-SY5Y cell was the most sensitive. This is not surprising as the central nervous system was pharmacologically determined as the target system for the biological effects of this plant thus a toxicity response might be anticipated in neuronal cells. In the present study it is suggested that the toxicity effects seen for MSE were predominantly due to MIT as shown by similar IC50 values for MIT and MSE treated SH-SY5Y cells. The role of metabolism was also assessed in which the toxicity of MSE treated SH-SY5Y cells was found to increase 10-fold when the metabolic activation system post mitochondrial rat liver S9 induced by Arochlor 1254 was added to the treatment.
The same outcome was also noted for caspase 9 assay which was performed using the same cell lysates (Fig. C and D). At the 24 hr time point of both caspase assays (Fig.
In the absence of rat liver S9 (Table 3. MIT was reduced to 17% of the concurrent vehicle control implying excessive toxicity effects. This was due to the measured RSG value being very low (18.
The results for MIT as shown in table 3. A and 3. B also revealed a negative outcome for genotoxicity under conditions with or without the presence of metabolic activation by S9. In this case the metabolic activation by S9 did not activate the toxic effects of MIT which was contrary to what we had seen for MSE. The survival rate was reduced to 17% of the vehicle treated control and this was thought due to the low viability rate (18. RSG) determined during the expression period (Table 3. The MF result for this concentration however was below the accepted criteria required to be positive.
