Cell lines HEK 293 MCL-5 and SH-SY5Y cells were used. These cell lines were cultured and maintained as described in chapter 2 section 2. Annexin V taking kratom tincture goehner conjugate staining kit 7-Amino-actinomycin D (7-AAD) dye and HEPES buffer were obtained from Invitrogen U. Describe Kratom High for cytological examinations Rapi-Diff staining was purchased from Bios Europe U. Wright-Giemsa
staining was from Sigma-Aldrich U. The opioid receptor kratom high effects antagonists naloxone naltrindole and cyprodime hydrobromide were purchased from Sigma-Aldrich U.
However the RTG was in the toxic range (10-20% reduced of the concurrent vehicle control). In addition the cloning efficiency of the cells or RSG value prior plating was also quite low (24%). 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.
Mitragynine is believed by many to be but has not been proven to be the primary active alkaloid in M. The effects of kratom can be kratom for sale los angeles coon rapids described as comparable to opium based-products but milder. In general the effects are stimulating and euphoric at a lower doses and are more calming and narcotic at higher doses.

However on the longer term effects of treatment (clonogenicity assay) as shown in fig. M naloxone was found not sufficient to inhibit the MSE toxicity at the same concentration used for previous experiments. M did give a positive response.

Many agents are currently known to induce cell death via caspase independent pathways as described above such as campothecin doxorubicin and paclitaxel. The necrotic type of cell death induced by MSE which is morphologically seen in cell lines such as MCL-5 and HEK 293 cells could not be confirmed biochemically due to time limitations. Unlike MSE MIT treated SH-SY5Y cells have shown a different mechanism of cell death in which there was an involvement of caspases 3 and Describe Kratom High 7.

. The opioid receptor antagonists naloxone naltrindole and cyprodime hydrobromide were purchased from Sigma-Aldrich U. IV set was from Calbiochem U. Caspase -8 and Caspase-9 Protease Kits were from Invitrogen U.
More recently mitragynine has been used in New Zealand for methadone addiction detox. It is widely known that kratom can have a positive effect on your mood and level of anxiety but there have been no studies on the long-term use. There are different types of kratom on the market: leaves powder and resin.
The nature of cell death and mechanism associated with it is yet to be reported. Thus in this part of this thesis several investigations were attempted to provide possible mechanism of the nature and mode of cell death seen with a selected panel of human cell lines. The cytological examination using three different cell lines (SH-SY5Y HEK 293 and MCL-5 cells) was the first investigation. As anticipated toxicity effects seen at high doses suggested apoptotic morphology with evidence of chromatin condensation which was predominantly seen in SH-SY5Y cells. Nuclear alterations are key in many descriptions of apoptosis. The severity of MSE insult in the SH-SY5Y cell line was obvious at the highest dose tested as there were very few cells present on the slide and all of them showed apoptotic morphology.

In this part of the study morphological features of the cells treated with MSE were cytologically examined using Wright-Giemsa or Rapi-Diff staining. Flow cytometry analysis using Annexin V conjugate assays were employed in order to distinguish the mode of cell death upon treatment with MSE and MIT. Biochemical analysis using caspase enzymes and fluorescent dye 27dichlorofluorescein diacetate (DCFH-DA) for detecting ROS generation in live cells were also conducted to confirm the mode of cell death. And finally the possible involvement of opioid receptors
in mediating the MSE and MIT cytoxicity has also been investigated.
