The SH-SY5Y cells were again used in this assay and the caspase inhibitors purchased from Calbiochem included Caspase-3 inhibitor II (Z-DEVD-FMK) Caspase-8 inhibitor II (Z-IETD-FMK) Caspase-9 inhibitor I (Z-LEHD-FMK) Caspase general inhibitor I (Z-VAD-FMK) negative control (Z-FA-FMK) and positive control doxorubicin HCL. Kratom Tolerance Effects Mays Landing m of each inhibitor 30 minutes prior to adding the MSE. C (5% CO2) for 48 hr time period. After incubation the cells were harvested and trypsinised as described in chapter 2 section 2.
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 Kratom Tolerance Effects Mays Landing DPX and were examined using Zeiss Axiovert 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).

The same outcome was also noted for caspase 9 assay which was performed using the same cell lysates (Fig. C and D). At the 24 hr time point of both caspase assays (Fig.

Or: an increase of small colony MF of at least 150 x 10-6 above the concurrent vehicle control. The test compound is regarded negative if the MF is less than the sum of the mean control mutation frequency plus the GEF. The test compound is regarded positive if the MF of any test concentration exceeds the sum of the mean control mutation frequency plus the GEF and there was a concentration dependent increase in MF. 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.

DNA damage as a result of endogenous sources (cellular metabolic processes) or exogenous sources (environmental factors such as chemical insult) could lead to reversible or irreversible genetic change. Based on the long term use of this plant by humans testing for its genotoxic potential using mammalian cells was thought to be more appropriate than conventional first tier testing for gene mutation in bacteria. In fact the primary first tier bacterial genetic toxicology assay the Ames Salmonella assay is incapable of detecting large scale deletion or recombination events of the mutations.

D) it appears that naltrindole again successfully inhibited MIT toxicity at all concentrations tested. Whereas for the longer term effects (clonogenicity assay) fig. M successfully gave protection against MSE toxicity at all dose range however it
was not that effective for MIT at high dose. MSE mediates its toxicity via this receptor as shown in acute treatment of MSE (trypan kratom dosage for euphoria blue exclusion Fig.
