Objective:
To
examine the effect of MGN-3 on HIV induced syncytia formation (SF) In Vitro.
MGN-3
is an arabinoxylane from rice bran, that is enzymatically treated with
an extract from Hyphomycetes mycelia.
Method:
Peripheral
Blood Lymphocytes (PBL) from AIDS patients were cultured with PHA in the
presence or absence of different concentrations of MGN-3 (12.5 - 100,v
g / ml) for 7 days. The number of syncytia were evaluated, and the size
of each was also recorded. The effect of MGN-3 on PHA induced PBL proliferation
was studied by MTT
assay.
Results:
Treatment
with MGN-3 resulted in:Significant inhibition in the SF,The effect was
dose dependent, percentage of inhibition in SF was 38.5, 50, 62.5, and
75% at concentrations of 12.5, 25, 50, and 100 p g / ml respectively; Complete
absence of SF having large and median size post treatment, and MGN-3 caused
25 - 30% inhibition of PBL proliferation.
Conclusion:
We
conclude that MGN-3 is a natural product that possesses a potent effect
against syncytia formation by HIV. This property of MGN-3 may be of potential
value in therapy of HIV infection.
