The presence of S9 appeared to have a substantial effect on the RTG with MSE. In fact there was a clear dose-dependant toxicity observed suggesting that the MSE was being activated to a toxic derivatives. MSE in the absence of metabolic activation with S9 did not produce evidence of genotoxicity (Table 3. MF values were all within negative criteria. In the absence of S9 MSE appeared to be toxic compared to the control (lower RTG).

Cyprodime hydrobromide (C). Nt ANOVA with Bonferroni post test. The nature of cell death and mechanism associated with it is yet to be reported. Thus in this part of this thesis several investigations were attempted to provide possible mechanism of the nature and mode of cell death seen with a selected panel of human cell lines. The cytological examination using three different cell lines (SH-SY5Y HEK 293 and Kratom Treatment Opiate Addiction MCL-5 cells) was the first investigation.
Thus the combination consumption of Mitragyna speciosa Korth leaves with CYP 2E1 inducers may shift toxicity closer to doses that are
pharmacologically active. Based on the current findings observed in the present studies it is concluded that the methanol-chloroform extract (MSE) of the Mitragyna speciosa Korth (Kratom) leaves and its dominant alkaloid mitragynine (MIT) have potential to cause cytotoxicity to mammalian cells at high doses and is possibly harmful to human users. MIT is proposed to be a major contributor to MSE cytotoxicity. The main target system of MSE and MIT cytotoxicity is the central nervous system as shown by sensitivity of neuroblastoma cell lines (SH-SY5Y) throughout the studies. In general MSE and to a lesser extent MIT were found to exert their dose
dependant cytotoxicity effects in all human cell lines examined Kratom Treatment Opiate Addiction both in acute treatment and also in the longer term as assessed by the clonogenicity assay. M arrest for HEK 293 cells.
Finally the slides were rinsed briefly in the buffered water (pH 7. The slides were mounted with DPX and microscopic examination was then carried out similarly as described for WrightGiemsa staining blue mitragyna speciosa procedure. AAD double staining for apoptosis detection In principle the cell membrane of live cells is covered by phospholipids (lipid bilayer) in which phosphatidylserine is located on the inner layer of the plasma membrane. In early stages of apoptosis the phosphatidylserine is exposed to the outer surface of the plasma membrane (Darynkiewicz et al 2001; Fadok et al 1992). Darynkiewicz et al 2001; van Engeland et al 1998). C (5% CO2) for 24 hour.

Programmed cell death or apoptosis is one way cells can commit to death induced by numerous factors. In the present study a possible involvement of caspase proteases both pro-apoptotic caspases (caspase 8 and 9) and executor caspases (caspase 3 and Kratom Treatment Opiate Addiction 7) were examined using commercially available kits as described in section 5.

Prior to this study most of the investigations on the biological effects of this plant such as antinociceptives effects were mostly comparisons Kratom Treatment Opiate Addiction with opiate drugs such as morphine and its related compounds. Thus an important issue is whether MSE or MIT induced cell death may share similar mechanisms as opiate induced cell death. In general opioids have been shown to induce in vitro apoptosis in cell lines including neuronal cells (Mao et al 2002).
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.

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 fda kratom import alert digestion via lysosomal pathway (Kerr et al 1972). Whereas necrosis described as a passive way of cell death is morphologically marked by cellular swelling chromatin condensation followed by cellular and nuclear lysis with subsequent inflammation (Wyllie et al 1980). Recently necrosis kratom effects was described as morphological alterations of cells after cell death (Majno and Joris 1995; Cruchten and Broeck 2002).
