Abstract

Doxorubicin as chemotherapeutic agent causes immunosuppresive. The aim  for this study to determine the effect of ethanolic extract of Taraxacum oficinale (ETO) in immunity system of Sprague Dawley  rat that induced  by doxorubicin to observe the profile of immunity cells. Sprague Dawley rats were divided into five groups each groups contain five rats : control doxorubicin group, doxorubicin dose 4,67 mg/kgBW+ ETO dose 1000 mg/kgBW, doxorubicin dose 4,67 mg/kgBW+ ETO dose 500 mg/kgBW, control extract group, and without treatment. Then the number of leukocytes, lymphocytes and neutrophils were analyzed  by hematology analyzer, whereas CD8+ T lymphocytes by flowcytometry. Results showed groups of  doxorubicin combined with ETO dose 1000 mg/kgBW and 500 mg/kgBW increased the number of leukocytes, lymphocytes, neutrophils,  cytotoxic CD8 + T cells  T cells compared  to control doxorubicin group. These data presents that etanolic extract of Jombang leaves has  immunostimulatory activity and potential as co-chemotherapy agents. Molecullar mechanism underlaying it’s immune activity need to be explored in detail.

Abstract

Hormone Replacement Therapy (HRT) is therapy for estrogen deficiency and post menopausal  syndromes,  but  high  cost  and  unwell-secured  therapy.  One  of  alternative therapy  is  the  usage  of  phytoestrogens.  The  banana  peel  contains  flavones,  flavonol, flavanone and polimethoxyflavone which are potential as phytoestrogen. The purpose of this study was to examine the estrogenic effect of banana peel extract (BPE) development of mammary gland of ovariectomized rats. Estrogenic effects was examined based on in vivo and in silico experiment. For in vivo experiment, female Sprague-dawley rats aged 50 days were ovariectomized. At 70 days of age, 12 rats were treated with BPE 500 mg/kgBB and 1000mg/kgBB, 5 rats were treated with estradiol 2g/day while others served as control were treated with CMC-Na 0.5% and sacrificed 2 weeks later. The base line ovariectomized rats and base line non-ovariectomized rats were sacrificed at 70 days of age. The in silico experiment examined by molecular docking between myricetin and estrogen receptor alpha (ER-α). The result of in vivo experiment showed that 1000 mg/kgBW BPE induced c-Myc expression  and  enhance  ovariectomized  rat  mammary  gland  development  significantly. Meanwhile, molecular docking showed that there are hydrogen bond interaction between bioactive compound in BPE and Estrogen Receptor (ER)-α but less powerfull than estrogen and ER-α interaction. In summary, BPE can act as an estrogen agonist,  resulting in the enhancement of c-Myc expression.
