In principle in DNA cycle analysis the movement of DNA profiles to the right side of the scale indicates more dye has been taken up. This would be the implication if the pores of the plasma membrane open or if there was a mechanism in which the dyes could diffuse more easily into the cell. Kratom Tea Recipe Vermillion another flow cytometry analysis was carried out in this chapter this time using double staining with Annexin V conjugates-7-AAD to further determine the nature of cell death.
A) which therefore affected the final calculation for the RTG. Preliminary data of MIT treated groups with and without the presence of S9. C MIT Treatment with S9 (3 hr) 30 20 10 5 DMBA
The term of apoptosis was first coined by Kerr et al (1972) and it was described as an active way of killing the cells and organising its disposal which was easily detected under a microscope as cells undergo condensation of nuclear chromatin followed by formation of blebbing and segregation of the nucleus into fragments known as apoptotic bodies and finally disposed of by digestion via lysosomal pathway (Kerr et al 1972). Whereas necrosis described as a passive way of cell death is morphologically marked by cellular swelling chromatin condensation followed by
cellular and nuclear lysis with subsequent inflammation (Wyllie et al 1980). Recently necrosis was described as morphological alterations of cells after cell death (Majno and Joris 1995; Cruchten and Broeck 2002).

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. K) and absorbance was read at 560 nm. One set of similar concentrations were also prepared as a negative control (without adding caspase substrate). NA) or caspase -9 (LEHD) substrate were added to the test samples.

Effects of MSE and MIT on p53 target gene product p21 It is well established that induction of p53 can lead to expression of target gene p21 and thereby cell cycle arrest. MSE even at the earliest time point 6 hr. Therefore to further determine whether p21 is positively linked with p53 in response to MSE or MIT we examined p21 levels using immunoblots. The quantitation of p21 protein is described in section 4.
The increase of subG1 population was also prominent at these two highest doses. DNA Kratom Tea Recipe Vermillion replication process occurring (increased S phase cells). This finding was found to be in contrast to the previous MCL-5 results (Fig.

MSE was found to be too toxic with RSG only 2% (Table 3. The results for MIT as shown in table 3. A and 3. B also revealed a negative outcome for genotoxicity under k2 kratom pills point vivian conditions with or Kratom Tea Recipe Vermillion without the presence of metabolic activation by S9.

SG (mean control SG) X 100 Based on the RSG value obtained the concentrations chosen for the plating (viability assessment and mutant frequency) includes at least one dose level with an RSG value of 10-20% a no effect dose and a minimum of two further doses between this range of concentrations. CM10 media was prepared in sterile universal bottles. The procedure was done under subdued light due to TFT sensitivity to light.

- Caspases enzyme assay Caspases play an important role in mammalian apoptosis
- P53 levels of MIT treated SH-SY5Y cells after 24 hr treatment
- In addition the evaluation of genotoxic potential of MSE and MIT at present is for academic purposes and not a regulatory requirement
- Or: an increase of small colony MF of at least 150 x 10-6 above the concurrent vehicle control
- Dried leaves can also be chewed but since they are a bit tough most people prefer to crush them up or powder them first
