The results from different cell lines used in the viability studies demonstrated that the human neuronal SH-SY5Y cell was the most sensitive cell line examined. Mitragyna Speciosa Live Plants For Sale the IC50 Mitragyna Speciosa Live Plants For Sale kratom withdrawal pain following 24 hr treatment of SHSY5Y cells were 91. MSE and MIT respectively. Analyses of MSE by UV-VIS spectroscopy confirmed the presence of MIT-like compound at a level of about 42% of the total extract indicating that the MSE IC50 of 91. M) as shown in this study. This result implies that MIT is one of the major compounds in the leaves of this plant contributing to MSE cytotoxicity. Apart from the acute cytotoxicity effects seen in different cell lines another major finding in this part of the study was the longer term cytotoxicity effects as determined by kratom on full stomach colony forming ability (clonogenicity assay).
This phenomenon creates disadvantages for this assay as when the whole FACS profile shifts to the right side of the scale the determination of the stages of cell death is difficult to interpret as the cells are no longer located in specific quadrants. This observation is clearly in Mitragyna Speciosa Live Plants For Sale contrast with the previous cytological examinations which indicated that SH-SY5Y cells treated with high dose of MSE undergo apoptosis rather than necrosis. The right shifting phenomenon for MIT treated cells observed in fig. For HEK 293 and CL-5 cells the effects seen were in agreement with the cytological examinations. Since the Annexin V-conjugate-7-AAD double staining provide inconclusive results especially for the SH-SY5Y cells further experiments looking at biochemical effects of MSE treatment was warranted. Discovery of a family of cysteine protesases named caspases (Srinivasula et al 2001; Alnemri et al 1996) in mammalian cells has made important discoveries towards its function in cell death mainly in apoptosis. Their characteristic ability is to perform proteolytic cleavage at defined aspartate acid residues in various cellular substrates (Srinivasula et al malaysian kratom caps 2001).
