| Summary: | Phyllanthus niruri is medical plant traditionally known for some of medication,
such as immunomodulator. The use of this plant such as nanoparticle formulation
using chitosan for co-adjuvant theraphy for increase immune system for HbsAg
in hepatitis cases. Acute toxicity study of Phyllanthus niruri on hematological test,
kidney and liver indicate there is no toxicity, while sub cronic toxicity on testis
show there are toxicity that cause hormonal imbalance and degenerative damage.
Sertoli cell is one of cell that give huge role on spermatogenesis. Disruption on
sertoli cels cause disruption on spermatogenesis that can impact on fertility. Non
classical testosterone signalling pathway is one of signalling that has roles on
maintain normal function of sertoli cells. Src and EGFR are some of protein that
are involved in this pathway. This study focuse on formulation and
characterization of nanoparticles Phyllanthus niruri, inhibition study of activation
on Src and EGFR using western blot method on TM4 cell line. TM4 cell line is
collected from sertoli cell of male mice. Size, polidispersity index, potential zeta of
this formula are 171 nm, 0,274 and +37,82 respectively. Entrapment efficiency is
75%,. IC50 value from viability study using CCK-8 is 206 ppm. Study of
activation inhibition of Src show that there are activation inhibition with
significantly different occur on nanoparticle PN 500 ppm group (p<0,5). Study on
EGFR show there are activation inhibition of EGFR on nanoparticle PN 7,81
ppm; 31,25 ppm; 125 ppm groups. Activation inhibition of Src and EGFR cause
disruption effect on spermatogenesis and male fertility. This results may indicate
there are disruption of sertoli-germ cell adhesion and release of mature
spermatid. |
