M naloxone was found not sufficient to inhibit the MSE is kratom legal in new zealand toxicity at the same concentration used for previous experiments. M did give a positive response. Kratom Withdrawal Cure effects of naltrindole on MSE and MIT treated cells: The effects of naltrindole on acute treatment (Fig. M concentration also gave some protection against MSE toxicity at high dose but not sufficient to be significant when compared to Control groups. D) it appears that naltrindole again Kratom Withdrawal Cure successfully inhibited MIT toxicity at all concentrations tested.
However due to its narcotism properties it has been misused by drug addicts as an alternative to opium or to moderate the withdrawal symptoms of opium. After years of research with this plant mainly using crude alkaloid extracts its dominant alkaloid mitragynine (MIT) and congeners their analgesic properties have been confirmed in vitro and in vivo –
- Dehyromitragynine: an alkaloid from Mitragyna speciosa
- However MIT in parallel experiments did not show any enhancement of toxicity in the presence of S9 and was inherently cytotoxic
- This result suggests that chloroform did not enhance MSE-dependant cytotoxicity
- Annals of the Brazilian Academy of Sciences 79: 593-616
- In this study SH-SY5Y cell death induced by MSE appeared to be independent of p53 and p21 pathway
. This medicinal property has so far been reported in the leaves of this plant but not from other species of Mitragyna. Several countries like Thailand Myammar Malaysia and recently Australia have made this plant illegal due to its narcotism properties whereas in other parts of the world the plant regardless of any form has been sold widely over the internet. Western culture is increasing and some individuals are now taking it for self-treatment in chronic pain and as an aid to opioid withdrawal (Boyer 2007). The potential toxicity of MSE and of other products derived from Mitragyna speciosa Korth is currently unknown.
Results of the preliminary assay as shown in fig. H202 significantly released ROS as soon as it was added to the cells (at the 30 minute time interval) and was consistently higher than other group treatments. The incubation of anti-oxidant NAC 30 minutes prior to adding H202 appears to reduce the ROS production. Interestingly both high doses of MSE and MIT appeared similar to control groups and indicate that there was no ROS generation in this cell line.
The DNA profiles of SH-SY5Y cells were also assessed after exposure to various concentrations of MIT at 24 hr treatment period (Fig. M MIT where cells accumulated at G1 phase and the population shifted to the right side of the scale. This phenomenon implies that the treated cells have taken up more PI dye thus leading to a shift to the right. Due to the amount of MIT compound available repetition of this experiment was not possible.
Cells treated with both high concentrations of MSE (Fig. A) and cells pre-treated with NAC appeared similar to Control group. This infers that MSE did not generate ROS which confirmed the earlier findng.
The executioner caspases are also known as downstream caspases as they depend on active initiator caspases for their activation by proteolytic cleavage (Srinivasula et al 2001). As anticipated there was no activation of caspases 3 and 7 activities in cells treated with high dose of MSE at both 4 hr and 18 hr incubation time points. Interestingly for MIT there was a clear significant difference of caspases 3 and 7 activities at both concentrations of MIT tested. This finding suggests that the mode of the cell death of MIT treated cells is dependant
on caspase 3 and 7 activation pathway.
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 does kratom help with tramadol withdrawal hour duration (refer to Kratom Withdrawal Cure table 4. The blots were then washed as before for three times. The membrane was incubated in chemiluminescent solutions (Supersignal Chemiluminescent substrates in 1:1 ratio Pierce Rockford IL) for 5 minutes at room temperature.
