Determine the possible mechanisms of MSE and MIT induced-cell death. Introduction MSE is a methanol-chloroform extract of Mitragyna speciosa Korth (MSE) or also known as alkaloid extract from which the dominant alkaloid mitragynine (MIT) is obtained. The chemistry and pharmacology of the leaves of this plant especially the extract and MIT has already been established and known to exert opioid agonistic effects (Jansen and Prast 1988 Thongpradichote et al 1998 Takayama 2004).

As a result the levels of other herbs or supplements may become too high in the blood. It may also alter the effects that other herbs or supplements possibly have on the P450 system.

However the potential cytotoxicity of this plant is unknown. Therefore the cytotoxicity of methanol-chloroform extract (MSE) and MIT on human cell lines (HepG2 HEK 293 MCL-5 cHol and SH-SY5Y cells) has been examined. SH-SY5Y was the most snsitive cell line examined. MIT showed a similar response. Clonogenicity assay was performed to assess the longer- term effects of MSE and MIT. The colony forming ability of HEK 293 and SH-SY5Y cells was inhibited in a dose-dependant manner. Involvement of metabolism in cytotoxicity was further assessed by clonogenicity assay using rat liver S9 (induced by Arochlor 1254); toxicity increased 10-fold in both cell lines.
Extraction using organic solvent (modification of Houghton and Ikram Method 1986) About 500 g of dried powdered leaves were soaked in 2 L of methanol for about 3 days. The mixture of methanol and the leaves were filtered and the filtrate was dried using a rotary evaporator. The crude methanol extract obtained appeared greasy with a dark green colour. The crude methanol extract was re-dissolved in 300 ml chloroform and the mixture was transferred into a separating funnel.
Various in vitro test systems are available to determine the cell death upon xenobiotic insult. This assessment can either be tailored to determine cell morphology characteristics biochemical or even the molecular changes. Various methods have been developed for identification of living and dead cells which could easily be differentiated during microscopic examinations or by other means such as fluorescence using a plate reader or by flow cytometry analysis.
Mmmm yummy! some Khat Kratom Cat Shit. Ibogaine is already Schedule 1 in the United States. We need to abolish the DEA.
The passage of a cell through cell cycle is governed by an independent control system that programmes the cell cycle event especially the S and M phase to be in the correct order at the specific Kratom Tea During Pregnancy intervals. These control systems are mainly proteins that exist in the cytoplasm of the cells; a family of enzymes called cyclindependant kinases (Cdks) and regulatory proteins called cyclins (Morgan 1997; Morgan 2008). Murray and Hunt 1993) and they bind tightly best kratom extract available with their regulatory subunit cylins to form a complex.
Tumour suppressor gene (TSG) another important gene that regulates the normal cell growth and mitosis also plays a significant role in cancer formation. In cases of cellular stress or DNA damage the TSG will suppress normal function and promote cell cycle arrest to allow enough time for repair and to prevent mutations from passing to new cells. However if the TSG itself has been mutated the original functions of it can be switched off and DNA damage without repair may lead to mutation.
