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.
CellQuest pro software. PI was excited at 488 nm using an Argon laser and the fluorescence analysed at 620 nm. Immunoblot For this experiment the procedure was adapted from Laemmli method (Laemmli 1970). SH-SY5Y cells were used as it was the most sensitive cell line for the toxicity effects of MSE and MIT.
Scoring the plates After the incubation period all the plates for kratom leaf high santa clara viability assessment were scored using a modified mirror box for the absence or presence of colonies in each well. The numbers of negative wells for viability plates and positive wells for mutant plates were also recorded. Test Acceptance Criteria and Evaluation of the Results Following the protocols obtained from GlaxoSmithKline Company (Ware U. K) the assay was accepted based on the measurement of cytotoxicity by relative total growth (RTG) which reduced to approximately 10-20% when compared to concurrent vehicle control. The mean vehicle control value for mutant frequency (MF) are between 50-170 x 10-6 The mean cloning efficiency is between 65-120%. The mean suspension growth are between 8-32 on day 2 (following 3 hr treatment with S9) After exclusion of obvious outliers at least 2 acceptable vehicle controls cultures mitragyna speciosa vendita east cambridge remain.

CYP 2E1 is an important xenobiotic metabolising enzymes for human and rodents which is expressed in the liver. CYP 2E1 can metabolise various substrates including paracetamol fluoxetin alcohol caffeine and many others (Tanaka et al 2000). CYP 2E1 inducers for example alcohol.
MIT has a lesser effect and cells arrest mainly at G1 phase in SH-SY5Y cells. The cell arrest occurring at high doses of MIT was found to be correlated with p53 and p21 expression although the expression changes were marginal compared to control and lower dose groups. The mechanism for cell cycle arrest in the cells treated with high doses of MSE remains unclear as there was no correlation with p53 and p21 as both proteins were kratom dosage guide erowid lost after the treatment.

The wells were stained with methylene blue (1% in 50% Kratom Pills Uk Mantachie methanol) and colonies that contained 50 or more cells were scored as survivors. Relative cell survival was expressed as percentage of appropriate vehicle-treated controls. 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. C (50 rpm speed) for 3 hr. After 3 hr incubation the cells were washed with PBS (for SH-SY5Y cells) or D-PBS (for HEK 293 cells) by centrifugation resuspended in drug-free medium and reseeded for clonogenicity as described above.

In traditional medicine the Thai people use kratom to treat diarrhoea. A small minority of users take it to prolong or intensify sexual intercourse. However the Thai government has banned the use of kratom and classed the plant as a drug in the same category as cocaine and heroin.

This finding again strongly supported the suggestion that MSE toxicity requires metabolic activation. However in parallel assessments MIT toxicity was not enhanced by metabolic activation. As previously noted the toxicity of MSE and to a lesser extent MIT was dosedependant and the SH-SY5Y cell was the most sensitive cell line examined.

Therefore it was assumed that the minor contamination of chloroform in both MSE and MIT was not contributing to the toxicity. We observed that MSE exerted dose dependent cytotoxicity with several human cancer cells both via trypan blue exclusion assay and clonogenicity assay. Most xenobiotics undergo metabolic activation in the process of exerting their cytotoxicity effects.
