Investigation of the possible role of metabolic involvement in the toxicity of MSE The effect of possible involvement of metabolism was investigated using post mitochondrial supernatant S9 from rat liver induced by Arochlor 1254 a kind gift from Prof. Costas Ionnides of University of Surrey U. MSE with or without S9 (8.
Great info page. Daniel Seibert in email btwnot just from his website). NO loss of potency whatsoever.
Flow cytometry analysis using Annexin V conjugate assays were employed in order to distinguish the mode of cell death upon treatment with MSE and MIT. Biochemical analysis using caspase enzymes and fluorescent dye 27dichlorofluorescein diacetate (DCFH-DA) for detecting ROS generation in live cells were also conducted to confirm the mode of cell death. And finally the possible involvement of opioid receptors in mediating the MSE and MIT cytoxicity has also been investigated. A diagram showing the extrinsic and intrinsic pathways of apoptotic cell death involving initiator caspases 8 and 9 and executioner caspases 3 and 7. The involvement of cell death receptors and its ligands p53 protein and chemicals released from mitochondria in completing the cell death cascade are also shown. This diagram is taken from Haupt et al (2003). Materials and methods 5.
Critics say it is more jittery than other Premium Thai strains and argue it is not as long lasting. The active dose is 1-2 grams. High quality Maeng Da is very green in color.

The limited amount of MIT available to me throughout the studies have restricted the testing of MIT in parallel with all MSE assessments. This limitation has compromised a comprehensive investigation on MIT induced cytotoxicity and cell death. It is therefore important for future in vitro investigations to look for morphological assessment of MIT induced cell death and further confirmation on the involvement of initiator caspases 8 and 9 to support the current findings. MSE and should be supported by in vivo studies. Metabonomic studies using cell lines or urine from animal models or perhaps urine from humans exposed to this plant are also suggested.
After 24 hr incubation the medium was aspirated and the cells were washed with PBS. Digital photographs were taken of each well at magnification x400. Two pictures were taken for each well as indicated in the figure 2 above. The medium was replaced and the cells were treated again as before and returned to incubator. This process was repeated at 48 hrs. This is a homogeneous fluorometric method for estimating non-viable cells and also kratom drug test probation to estimate the total number of cells present in culture.
The mouse lymphoma tk gene mutation assay (MLA) is widely kratom extract tablets used and an accepted test system for the assessment of mammalian cell gene mutation; it involves assessment of the thymidine kinase (tk) locus using mouse lymphoma L5178Y cells. The
capability of MLA
to detect the chromosomal mutations is important as mutations play a central role in carcinogenesis (Mitchell et al 1997). The end point of this test evaluating the size of the colony formations determines the type of chromosomal changes induced. Small colony mutants are always a main concern as these have been shown predominantly due to the loss of all or a significant portion of the functional tk allele (Clive et al 1990) as a consequence of structural or numerical alterations or recombinatorial events. In pharmaceuticals safety testing MLA is considered to be an acceptable alternative to the direct analysis of chromosomal damage in in vitro tests such as hypoxanthine-guanine phosphoribosyl transferase (HPRT) (ICH 1997) or in vitro chromosomal aberration test (Honma et al 1999).
AbD Serotec U. The cells were returned to the incubator for another 24 hr and another reading was made at the 48 hr time point. MIT concentrations as described earlier and the cells were incubated for 48 hr time point.

After this incubation the cells were harvested as previously described (section 2. 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 stained with Wright-Giemsa staining. Briefly the slides were fixed with absolute methanol for three minutes followed by immersion in Wright-Giemsa stain for 1 minute rinsed in PBS for 1 minute and finally in water for 1 minute. The slides were mounted with DPX and were examined using Zeiss Axiovert kratom online shop 200 widefield microscope at 1000x magnification. For MCL-5 cells after designated incubation period the treated cells were transferred into a centrifuge tube followed by centrifugation (1000 rpm for 5 minute).
