Never use heavy machinery drive or perform any other hazardous activity while under the influence of kratom. Even if you feel stimulated rather than sleepy sleepiness may come on you without warning. Use your common sense. Pregnant or breast-feeding women and children under 18 should not take any drug or medicationexcept on medical advice. We strongly advise that any woman who could possibly be pregnant NOT use kratom. Combining drugs is usually a bad idea.

These higher doses of MSE also substantially increased cell death within 24 hr (Fig. As with the other of cell lines this inhibition of proliferation was accompanied by a dose-dependent increased cell death (Fig. M MIT (Table 2.

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.

Thus the combination consumption of Mitragyna speciosa Korth leaves with CYP 2E1 inducers may shift toxicity closer to doses that are pharmacologically active. Based on the current findings observed in the present studies it is concluded that the methanol-chloroform extract (MSE) of the Mitragyna speciosa Korth (Kratom) leaves and its dominant alkaloid mitragynine (MIT) have potential to cause cytotoxicity to mammalian cells at high doses and is possibly harmful to human users. MIT is proposed to be a major contributor to MSE cytotoxicity.

The necrotic type of cell death induced by MSE which is morphologically seen in cell lines such as MCL-5 and HEK 293 cells could not be confirmed biochemically due to time limitations. Unlike MSE MIT treated SH-SY5Y cells have shown a different mechanism of cell death in which there was an involvement of caspases 3 and 7. This is consistent with the immmunoblot finding which indicates that p53 and p21 proteins were marginally expressed even at high doses of MIT. These findings indicate that MIT treated SH-SY5Y cells may execute cell death via an apoptosis pathway. If time had permitted more detailed examination of the involvement of caspases and other apoptosis-related proteins in MIT treated cells would have been desirable.

S9 did not influence the MIT metabolism as the cells number were within the similar range as cells in negative control groups or positive control group and the RSG values were high and not much different with other groups.

For cytotoxicity assay; MSE treated HepG2 cells were cultured as described in section 2. C for 10 min. The reaction was terminated with stop solutions provided with the kit. The plate was read using a fluorescent plate reader with an excitation wavelength of 560 nm and emission wavelength of 590 nm.
