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 Strongest Kratom To Buy Williston liver S9 for at least 2 days and sub cultured to determine cytotoxicity and also to allow phenotypic expression prior to mutant selection. Strongest Kratom To Buy Williston cytotoxicity was determined by measuring the relative total growth (RTG) of the cultures after the treatment period.
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.

Sample cocktail buffer (0. C for 5 minutes. 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.

In this study SH-SY5Y cell death induced by MSE appeared to be independent of p53 and p21 pathway. However the morphological features indicated apoptoticlike type of cell death. Based on these findings it was postulated that the mechanism of cell death of SH-SY5Y cells upon MSE treatment may not follow the common intrinsic pathway which requires the activation of tumour suppressor protein p53.

The stimulation effects claimed at low doses are based on anecdotal reports from users however the specific
clinical pharmacology how to use kratom resin extract and controlled dosage for humans is still poorly understood. One of the main reasons for conducting toxicology studies is to determine the risk or in other words to determine the potential for harm towards human health or the environment upon exposure to naturally occurring or synthetic agents. Thus the findings of this study will hopefully contribute to a better understanding in predicting the risk upon consuming Mitragyna speciosa Korth leaves.

The blocking solution was poured off and the membrane was washed twice with PBST each for 5 minutes duration. After washing the membrane was incubated in appropriate primary antibody prepared in blocking solution (refer to table 4. C) on the tilt table overnight. The membrane was washed again with PBST three times for 10 minutes duration each time and the appropriate secondary antibody (horseradish peroxidase conjugated) was added and further incubated in room temperature on the tilt table for 1 hour duration (refer to table 4.
With MIT treatment groups (Fig. B) similar findings were clearly seen. NAC appeared no different compared to Control group.
Mouse Lymphoma Thymidine Kinase Gene Mutation Assay. Van Engeland M. Annexin-V-affinity assay: A review on an apoptosis detection systembased on phosphatidylserine exposure.
AAD double staining was carried out using SH-SY5Y and MCL-5 cells treated with MSE and MIT as described in section 5. As translocation of phosphatidylserine to the outer plasma membrane
indicates early apoptotic cell death Annexin V staining was used as a marker for apoptotic cells (van Engeland 1998). The cells become reactive with Annexin V prior to the loss of the ability of the plasma membrane to exclude 7-AAD staining and thus enables detection of unaffected (live) cells early apoptotic necrotic and late apoptotic cells (Darynkiewicz et al 2001).
