ROS generated from mitochondria of SH-SY5Y cells was measured by fluorescence in which the intensity of fluorescent product DCFH is proportional to the levels of intracellular ROS generated. Results of the preliminary assay as shown in fig. H202 significantly released ROS as soon as it was added to the cells (at the 30 minute time interval) and was consistently higher than other group treatments.

Increasing subG1 phase was noted for all dose ranges tested at 48 hr treatment period indicating an increase of the toxicity over time. The subG1 phase has been proposed to be a population of apoptotic cells (Darzynkiewicz et al 1992). Effects of MSE on cell cycle distribution of HEK 293 cells after 24 and 48 hours of treatment. Histograms are representative of three replicates of experiments with similar results and analysed by Cellquest Pro software. Values of each phase of the cell cycle were the mean of the three experiments with SEM.

MSE in the presence of S9 reduced the colony formation to less than 10% of the vehicle treated control. A similar outcome was seen using S9 with L5178Y cells in this assay in the preliminary tests for selecting the range of concentrations performed prior to plating assessment. 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.
Protein determination was performed using BCA protein assay kit (Pierce Rockford IL) following the manufacturers instructions and the absorbance of protein was determined at 580 nm wavelength. Sample cocktail buffer (0. C for 5 minutes.
The trypan blue assay and clonogenicity assay were employed as described in chapter 2 section 2. MSE and MIT are discussed as follows: Effects of naloxone on MSE and MIT treated cells: Fig. Naloxone also appears to successfully inhibit the MIT toxicity (Fig. However on the longer term effects of treatment (clonogenicity assay) as
shown in fig.

The blots were then washed as before for three times. The membrane was incubated in chemiluminescent solutions malaysian kratom capsules (Supersignal Chemiluminescent substrates in 1:1 ratio Pierce Rockford IL) for 5 minutes at room temperature. The best kratom recipes membrane was placed in a metal cassette and exposed to hyperfilm (Amersham Germany) in the dark room for an appropriate time period and was developed in an automatic developer.
Unsuccessful repair processes may lead the what kratom is strongest cells to undergo apoptosis. In mammalian cells an important protein that plays a central role in cell cycle arrest is p53. Norman et al 2005). These reports confirm the complexity of maintenance of the cell cycle.
The stimulation effects claimed at low doses are based on anecdotal reports
from users however the specific clinical pharmacology and controlled dosage for humans is still poorly understood. One of the main reasons for conducting toxicology studies is to determine the risk or in other words to determine the potential for harm towards human health or the environment upon exposure to naturally occurring or synthetic agents.
Thus the findings of this study will hopefully contribute to a better understanding in predicting the risk upon consuming Mitragyna speciosa Korth leaves.
Prior to this study MIT was thought to be the compound responsible for the narcotic effects of this plant. In the early part of this study basic in vitro toxicology revealed that MSE and MIT have dose dependant toxicity to several human cell lines and the SH-SY5Y cell was the most sensitive. This is not surprising as the central nervous system was pharmacologically determined as the target system for the biological effects of this plant thus a toxicity response might be anticipated in neuronal cells.
