Parallel immuno blotting experiments were also carried out for MIT as shown in fig. There was no significant difference in the p53 levels noted over the dose range used however they appeared to be down regulated compared to the control group. Best Opiate Rehab Stafford green malay kratom kratom capsules swallow experiences the time course of MIT induced p53 change was also carried as shown in fig.

The limited amount of MIT available to me throughout the studies have restricted the testing of MIT in parallel with all MSE assessments. This limitation has compromised a comprehensive investigation on MIT induced cytotoxicity and cell death. It is therefore important for future in vitro investigations to look for morphological assessment of MIT induced cell death and further confirmation on the involvement of initiator caspases 8 and 9 to support the current findings.

M showed significant differences compared to control group for all fluorometric readings. For 18 hr incubation time period (Fig. B) again there was no significance difference between MSE treated groups and control group.

Throughout the past decade there have been many changes in our world. Now at the molecular level we are finally beginning to witness the emergence of entirely new chemical structures as we diligently struggle to discover the exciting new applications they have to offer. That is a world were education and professionalism reign supreme.

The data also suggested that the cell membrane integrity was compromised leading to the loss of cell content 15x kratom review possibly through membrane opening or increased membrane permeability. 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).

These assays were carried out according to manufacturer instructions. MSE for 4 hr and 24 hr incubation time points. After incubation the cells were harvested by routine trypsinisation procedure as described in chapter 2 section 2. Then the lysates were centrifuged at 10000g for 1 minute and the supernatant (cytosol exract) was collected and kept on ice. B(containing 4% cupric sulphate):A (containing sodium carbonate sodium bicarbonate bicinchoninic acid and sodium tartrate in 0. M sodium hydroxide) (Pierce U.

E) giving protection against MSE toxicity at high dose. F cyprodime hydrobromide also gave some protection effects against MIT toxicity (as measured by trypan blue exclusion). M concentration (Fig. Naloxone ANOVA with Bonferroni post test.

The percentage of subG1 population unfortunately was not determined during the analysis and the evaluation of this population was qualitative. MSE for 48 hr time period (Fig. MSE the cells in the G1 phase appeared to decrease but the overall profile was considerably altered. MSE the temporal aspects of these changes were examined.

P21 levels of MSE treated SH-SY5Y cells at different time points (6 12 24 and 48 hr). The blots were representatives of duplicate experiments. P21 levels of MIT treated SH-SY5Y cells at different time points (6 12 24 and 48 hr). M for MSE and MIT respectively (Chapter 2). The nature of cell death observed was unknown and to the best of my knowledge there are no reports or information available on Mitragyna speciosa Korth toxicity on mammalian cells. In this study therefore an attempt was made to characterise the MSE and MIT toxicity by looking at cell cycle distribution. Firstly attempt was made to look at the cell cycle distribution in different cell lines using flow cytometry approach.

Introduction Cytotoxicity and genotoxicity status of MSE and MIT were established in the previous chapters and both agents were determined to be toxic at high dose but not genotoxic. The molecular events leading to toxicity are yet to be fully understood. Cell cycle is an essential process for all living organisms with the ultimate goal to create new cells necessary for maintaining continued survival. Under normal circumstances the four phases of the cell cycle G1 S G2 and M phases are tightly regulated.

After washing the membrane was incubated in appropriate primary antibody prepared in blocking solution (refer to table 4. C) on the tilt table overnight. The membrane was washed again with PBST three times for 10 minutes duration each time and the appropriate secondary antibody (horseradish peroxidase conjugated) was added and further incubated in room temperature on the tilt table for 1 hour duration (refer to table 4.
