It has been noted that plants grown in cold climates are weaker. Kratom tea can be stored in the refrigerator for several days. Kratom extract can be stored for a couple of weeks until use. Great kratom stimulant strain mingo sumatra red vein kratom info page.
These observations give information that there are possibly other chemicals present in the MSE that could have together with NAC maintain the cell growth in media that lack nutrients thereby kratom tea extract permitting the cells to survive longer. Tchounwou 2007) and also plays an important role in the production of glutathione to help prevent oxidative stress (De Vries and De Flora 1993). MIT (Watanabe et al 1997; Thongpradichote et al 1998) could
play important roles in mediating the cytotoxicity effects seen so far. This result implies that there are possibly other chemicals present in the leaves of this plant which could be contributor
to the MSE cytotoxicity. There is an increasing popularity of use of Mitragyna speciosa Korth (Kratom) leaves as self-treatment for opioid withdrawal and chronic pain among Americans (Boyer et al Kratom Salem Oregon 2007). This in fact reflects increasing interest in constituents of this plant MIT and its congener 7-hydroxymitragynine which have been salviadee brand kratom extract x30 powder shown to exert potent analgesic effects in various in vivo and in vitro studies (Matsumoto et al 2004). Furthermore with the recent report on the use of this plant to treat chronic pain with lesser effects of withdrawal compared to opioid prescription treatment people are using this plant as an alternative to opium drugs (Boyer et al 2008).
The end point of this test evaluating the size of the colony formations determines the type of chromosomal changes induced. Small colony mutants are always a main concern as these have been shown predominantly due to the loss of all or a significant portion of the functional tk allele (Clive et al 1990) as a best legal opiate substitute consequence of structural or numerical alterations or recombinatorial events. In pharmaceuticals safety testing MLA is considered to be an acceptable alternative to the direct analysis of chromosomal damage in in vitro tests such as hypoxanthine-guanine phosphoribosyl transferase (HPRT) (ICH 1997) or in vitro chromosomal aberration test (Honma et al 1999).
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. Interestingly in the absence of S9 MIT showed dose-dependant cytotoxicity (low RSG) on its own. The preliminary data shown here are the results taken after 2 days expression period prior to plating.
