Mitragyna Speciosa – Bali Kratom Powder

C prior reading the absorbance at 405 nm using plate reader. Mitragyna Speciosa – Bali Kratom Powder then the cells were treated with MSE and MIT for 4 hr and 18 hr incubation time points. After each incubation time point the cells were harvested by trypsinisation and centrifugation as described in chapter 2 section 2.

Wound study or also known as wound healing assay is a simple inexpensive method to estimate the migration and proliferation Mitragyna Speciosa – Bali Kratom Powder rates of different cells under different culture conditions. The method has been described as a wound healing assay as it mimics cell migration during wound healing kratom very high dose in vivo (Rodriguez et al 2005). As described in the procedure in section 2.

MSE there was a pronounced loss of cell number below the initial seeding density. The IC50 for this cell at 24 hours treatment is 282. Proliferation (A) and percentage of dead cells (B) in MSE treated cHol cell cultures Mitragyna Speciosa – Bali Kratom Powder as determined by the Trypan blue exclusion assay.

The recent review by Zhang et al (2008) stated that morphine for instance induces neurotoxicity and apoptosis after chronic use and heroin also induced apoptotic cell death via mitochondrial malfunction caspase activation leading to PARP cleavage and DNA fragmentation. Thus MIT may show a similar trend of apoptotic cell death as opiates but confirmation of this finding requires further investigations. MSE as death appears to be caspase-independent and thus chemicals other than MIT present in MSE appear to complicate the interpretation of my biochemical findings.

In order to assess these effects more fully the well established Modfit software was employed for more detailed cell cycle analysis. In general the DNA profiles for MSE treated MCL-5 cells (Fig. MSE table 2. MSE suggested that 24 hr was the time point at which the changes began to be noted. On reflection the interpretation of these latter experiments would have been improved by 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.

Effect of MSE and MIT on p53 protein levels SH-SY5Y a neuroblastoma cell known to have wild type p53 (Moll et al 1995 1996) was examined by immunoblotting as described in section 4. Image J version 1. The effects of MSE on p53 expression levels were assessed. The p53 protein level was found to be decreased in a dose-dependant manner especially at lower concentrations of MSE treatment for 24 hr as shown in fig.

On this basis it was assumed that the positive effect was due to the excessive cytotoxicity in line with the ICH S2A guidelines (1995) and the result is considered invalid. The other concentrations tested were negative for genotoxic potential. The presence of S9 appeared to have a substantial effect on the RTG sumatra kratom forum with MSE. In fact there was a clear dose-dependant toxicity observed suggesting that the MSE was being activated to a toxic derivatives. MSE in the absence of metabolic activation with S9 did not produce evidence of genotoxicity (Table 3.

The values were interpolated from percentage dead cells curves obtained from the Trypan blue exclusion experiments. MIT (Molar) 7. MSE and MIT.

M) was then added to the wells under subdued lighting and NAC was also added to appropriate wells. C (5% CO2) for 30 minutes. As the addition of DCFH-DA dye led to precipitation as seen in the preliminary experiment after 30 min the cultured solutions were aspirated and fresh PBS (1 ml) was added to each well prior to adding the test compounds (H202 MSE is red vein kratom good and MIT). The fluorescence readings were then taken every 10 minutes interval up to 1 hr as described earlier. Trypan blue exclusion and clonogenicity assays were employed in this study –

This inhibition of proliferation persisted up to 72 hr (the duration of the study). Using pure compound MIT induced a differential response with the HEK 293 cells. At very low doses (3.

Such events are more common in mammalian cell mutagenesis (Clive et al 1990). Mitchell et al 1997). In general MSE with or without the presence of metabolic activation (Arochlor 1254 induced rat liver S9) was negative for genotoxic kratom opiate withdrawal dosage potential.
