The effect of Curcuma Longa Aegle Marmelos and Andrographis Paniculata in Plasmodium YoelII 17X (Lethal) strain-infected ICR mice
Abstract:
Malaria remains a major global health concern in the endemic countries
including Thailand because of malarias resistance of current antimalarial drugs.
Therefore, it has become urgently necessary to look for novel, effective, along with
inexpensive, antimalarial agents. Many countries around the world including
Thailand still use local traditional medicine for controlling the disease. Thailand is
a tropical country with rain forests and has a variety of traditional herbal plants,
some of which have been reported to be effective and promising medicines. Thus,
our purpose for this experiment was to study the effect of easily found local herbs;
Curcuma longa, Aegle marmelos and Andrographis paniculata; on Plasmodium
yoelii 17X (lethal) strain-infected ICR mice. Seventy-five 7-week old female ICR
mice were used and divided into five groups randomly. Group 1, 2, 3, 4 and 5
served as control, placebo, and 3 experiment groups for 3 proposed herbs,
respectively. Three concentrations at the dosages of 20, 40 and 60 mg/kg body
weight were used in each herb treatment. At day 0, 106 of P. yoelii 17X (lethal)
strain were inoculated into all mice. From day 1, thirty percent ethanol was given to
the placebo group whereas experimental groups were each given a concentration of
each herbal plant. The percentage of parasitemia were checked daily by tail snip
breeds with Giemsa staining and statistically analyzed by using student t-test and
justified at p-value < 0.05 as the significant difference. We discovered that there
was no suppressive effect of A. paniculata and C. longa on infected-mice;
however, 20 mg/kg of A. paniculata could lenghthen the life span of mice. For A.
marmelos, 20 and 40 mg/kg dosages displayed a suppressive effect on parasite
infection. Mice treated with 20mg/kg of A.marmelos also could live longer if
compared to the control mice. In conclusion, from the results of the experiment, A.
paniculata and A. marmelos may be two of the most promising novel medicinal
plants to help extend the life span of malaria infected mice.
