The treatments were done in triplicate. Immediately after the treatment period cells were harvested as described in chapter 2 section 2. The fixed cells were then centrifuged (1200 r.
Other pathways may be considered for MSE induced cell death with no involvement of caspase activation but yet following the programmed fashion. Involvement of several enzymes from lysosomal pathways such cathepsins and calpains were shown to highly correlate to apoptotic-like or even necrotic cell death (Jiang et al 2006; Yamashita et al 2003). Mitochondria which play a key role in the intrinsic pathway for apoptosis may also again be involved as apoptotic inducing factor (AIF) which is usually released after activation of Bcl-2 family acted with the EndoG protein released from plasma membrane to trigger apoptotic-like cell death ( Jiang et al 2001).
The cells were then buy kratom 15x capsules ready to be used for the assay. The chemicals used in the assays unless indicated in the text were obtained from Invitrogen Company (U. K) and Sigma-Aldrich Company (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 maeng da kratom capsules dose predominantly Kratom Source Strain Y Wisner 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 Kratom Source Strain Y Wisner 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 peak was also observed in MSE. 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 extract is found from the leaves of the plant. MSE sample was dissolved in is kratom illegal in new zealand absolute ethanol and thai kratom resin effects centrifuged at 1000 r. Trimethylsilyl)propionic-2233-d4 acid sodium salt (TSP) which act as a standard reference signal was added to the sample.
