This can be stored for later use. Kratom Effects Comparison Corry small pellets of this extract (which is also sold as such in various shops) can be swallowed or can be dissolved in hot water and consumed as a tea. Some people like to mix kratom tea with ordinary black tea or other herbal teas before it is consumed. Sugar or honey can be added to sweeten it.
C (5% CO2) for the designated time period. 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.

In early stages of apoptosis the phosphatidylserine is exposed to the outer surface of the plasma membrane (Darynkiewicz et al 2001; Fadok et al kratom nod dose 1992). Darynkiewicz et al 2001; van Engeland et al 1998). C (5% CO2) for 24 hour. After routine harvesting as described in chapter 2 section 2. PBS followed by centrifugation (1200 r. Cells were re-suspended in Annexin-binding buffer (10mM HEPES 150 mM NaCl and 2.
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.
For MCL-5 cells (Fig 5. The majority of the cells were evidently located in the Q3 and Q4 indicating the necrotic and late stage of apoptotic populations. This finding supports the cytological examinations previously noted where the cells were predominantly necrotic and in the late stage of apoptosis.
Programmed cell death or apoptosis is one way cells can commit to death induced by numerous factors. In the present study a possible involvement of caspase proteases both pro-apoptotic caspases (caspase 8 and 9) and Kratom Effects Comparison Corry 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).
Furthermore the cell cycle protein analysis (p53 and p21) performed using immunoblotting approach indicates the loss of these proteins at high doses of MSE and to the lesser extent MIT. The mechanism of this phenomenon is not obvious. However one hypothesis that could be proposed is the possibility of the membrane integrity being compromised especially at high dose of treatment or in other words the lost of cell content through membrane opening.
A standard curve for MIT was generated (Fig. The absorbance reading for each MSE fraction at 227 nm wavelength was recorded. Using the equation derived from the MIT standard curve an estimation of MIT present in each MSE fraction was calculated (refer to Appendix 1 for details of calculations). Based on this calculation it was estimated that MSE contained approximately 42% MIT-like compound. Absorbance 227 nm 2 1.
As with the other of cell lines tis inhibition of proliferation was accompanied by a dose-dependent increased cell death (Fig. M MIT (Table 2. The estimated IC50 values of these cells at 24 hr treatment were 91. Vehicle treated control 0.
