Based on UV-VIS spectrometer analysis MSE extract obtained by kratom effects experience this method was estimated to contain approximately 42% of MIT-like compound. Since the percentage of MIT present in the MSE is high MIT was assumed to be the major contributor for the MSE effects. Premium Indonesian Kratom Effects zombie kratom effects Putnam however it should be born in mind that the methanol-chloroform extract of Mitragyna speciosa Korth used in the current study (MSE) was prepared to maximise the MIT-like chemical content of the extract and is probably not bioequivalent to aqueous extract that humans are exposed to as the result of chewing leaves. Prior to this study MIT was thought to be the compound responsible for the narcotic kratom dried leaf effects of this plant. In the early part of this study basic in vitro toxicology revealed that MSE and MIT have dose dependant toxicity to several human cell lines and the SH-SY5Y cell was the most sensitive.
Activity of initiator caspase 8 after A) 4 hr incubation and B) 24 hr incubation time period and initiator caspase 9 after C) 4 hr incubation and D) 24 hr incubation time period of SH-SY5Y cells treated with MSE. The reading of each concentration is from 2 pooled lysates. SH-SY5Y cells treated with high dose of MSE and MIT incubated for 4 and 18 hrs respectively as described in the section 5. As shown in fig. A there was a non-significant Premium Indonesian Kratom Effects Putnam difference noted for caspase 3 and 7 activities for MSE treated cells compared to control groups at 4 hr incubation time point.

On reflection the interpretation of these latter experiments would have been improved by Premium Indonesian Kratom Effects Putnam comparison to control groups for each time points. Subsequently the cell cycle distribution of SH-SY5Y cells treated with MSE and MIT was examined as they were the most sensitive cells examined to date. MSE in this cell line revealed that cell cycle arrest was again noted at 24 hr and more prominent at G1 phase. Again on reflection inclusion of control group for each time points would have aided interpretation of these experiments. Based on the results of the three different cell lines examined it is suggested that MSE causes cell cycle arrest at G1 phase and S phase.
Although to date there is no report of cancer associated with consuming the leaves of this plant a genotoxic assessment such as mutagenicity aids prediction of red vein kratom seeds carcinogenicity potential. Thus for the first time I have shown that genotoxicity testing using the mouse lymphoma tk gene mutation assay (MLA) suggests that MSE and MIT have no genotoxic potential. This MSE toxicity was similar to that noted for MSE with the human cell lines (SH-SY5Y and HEK 293 cells) in the presence of S9.
In this chapter further investigation was attempted to explain these observations and to examine the mode of cell death of the cells treated with MSE and MIT. In general the two distinct pathways of cell death are via apoptosis or necrosis which are distinguishable morphologically and biochemically (Majno and Joris 1995; Wyllie et al 1980). The term of apoptosis was first coined by Kerr et al (1972) and it was described as an active way of killing the cells and organising its disposal which was easily detected under a microscope as cells undergo condensation of nuclear chromatin followed by formation of blebbing and segregation of kratom illegal in germany the nucleus into fragments known as apoptotic bodies and finally disposed of by digestion via lysosomal pathway (Kerr et al 1972). Whereas necrosis described as a passive way of cell death is morphologically marked by cellular swelling chromatin condensation followed by cellular and nuclear lysis with subsequent inflammation (Wyllie et al 1980). Recently necrosis was described as morphological alterations of cells after cell death (Majno and Joris 1995; Cruchten and Broeck 2002).
Based on this information it may be prudent to advise when consuming the leaves of this plant with any CYP 2E1 inducers such as alcohol; it might trigger greater toxicity effects. MLA in this study revealed that MSE and MIT have no genotoxic potential which is consistent with a lack of published evidence on the incidence of tumours or cancer in human upon consuming the leaves of this plant. In determining the mechanism of cell death induced by MSE and MIT it was noted that MSE caused a different mode of Premium Indonesian Kratom Effects Putnam cell death depending
on cell type. Morphologically after MSE insult SH-SY5Y cells appeared to die via apoptosislike cell death whereas MCL-5 and HEK 293 cells show predominantly a necrotic type of cell death.
