The mutant frequency value was determined from the derived number of mutant colonies in medium containing TFT and the number of colonies growing in nonTFT medium. The preliminary data on selection of dose range and final summary of the MLA results for the MSE and MIT are discussed below: 3. Mitragyna Speciosa History mLA for MSE As shown in table 3.
The pre-prepared polyacrylamide gels (varied depending on the size of protein of interest refer to table 4. Volts in running buffer (3g Tris 15 g glycine and 5 g SDS in 1L distilled water). The presence of protein on the nitrocellulose membrane was checked using ponceau S red staining.

C (5% CO2) for the designated time period –
- On this basis it was assumed that the positive effect was due to the excessive cytotoxicity in line with the ICH S2A guidelines (1995) and the result is considered invalid
- Mouse lymphoma cells in this assay were exposed to the MSE or MIT both with or without metabolic activation system Arochlor 1254 induced rat liver S9 for at least 2 days and sub cultured to determine cytotoxicity and also to allow phenotypic expression prior to mutant selection
- Use of flow and laser-scanning cytometry in analysis of cell death

. The adherent cells (HEK 293 and SH-SY5Y cells) were harvested trypsinised and centrifuged as per routine procedures described in chapter 2 sections 2. 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.

The blots were representatives of duplicate experiments. P21 levels of MIT treated SH-SY5Y cells at different time points (6 12 24 and 48 hr). M for MSE and MIT respectively (Chapter 2).
At 96 hr time point the G1 phase cells were observed to be higher than the other time points. Effect of MSE on the cell cycle distribution of MCL-5 cells after 24 and 48 hr treatment. Histograms are representative of three replicates of experiments with similar results and analysed by Modfit software.
Thirty thousand (30000) cells were analysed for each treatment using FLOW JO 8. Caspases enzyme assay Caspases play an important role in mammalian apoptosis. In this part of the study two initiator caspases caspases-8 and 9 and two executioner caspases 3 and 7 were used to investigate the mechanism of caspase activation in MSE and MIT induced cell death. In parallel caspase inhibitors were employed to confirm the outcome of the former assays. The caspase-8 and caspase-9 colorimetric assays purchased from Invitrogen U. IETD and LEHD respectively.

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 both 4 hr and 24 hr incubation time period (Fig. A and B). The same outcome was also noted for caspase 9 assay which was performed using the same cell lysates (Fig.
In order to assess these effects more fully the well established Modfit software was employed for more detailed cell cycle analysis. In general the DNA profiles for MSE treated MCL-5 cells (Fig. MSE table 2.

At higher doses mitragynine increasingly stimulates mu receptors. This is believed to be the reason that kratom has a stimulating effect at lower doses and narcotic effects at higher doses and that it is not (strongly) addictive. Nowadays most users describe the effects as stimulating and euphoric for some it also has a relaxing and analgesic effect. People report feeling euphoric but kratom powder how to prepare still energetic enough to function normally. Most sources say that it is a stimulant in lower doses becoming sedative in higher doses.
MLA for MIT The
preliminary data shown in table 3. S9 did not influence the MIT metabolism as the cells number were within the similar range as cells in negative control groups or positive control group and the RSG values were high and not much different with other groups. Interestingly in the absence of S9 MIT showed dose-dependant cytotoxicity (low RSG) on its own. The preliminary data shown here are the results taken after 2 days expression period prior to plating.
Although to date there is no report of cancer associated with Mitragyna Speciosa History 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) in the presence of S9.
