It is abundantly clear that the incidence of all
the common cancers in human is being
determined by various potentially controllable
external factors.
This is surely the most comforting fact to come
out of all cancer research, for it means that
cancer is, in large part, a preventable diseases.

CONCLUSSION
1.
Drinking ginger water extract for 30 days did not lower
blood cholesterol levels nor reduce plasma MDA
2.
However there was significant resistance to oxidation of the
LDL against induced oxidative stress
3.

CONCLUSSION
• In human study, using male adult healthy subjects, there is improvement in T cells
proliferation activities and percentage.
• Improvement on T cells was accompanied by resistance of lymphocyte cells against
oxidative stress. This improvement was demonstrated by the cells obtained from the
subjects drinking ginger
• Resistance of the lymphocytes was not accompanied by decrease in MDA cell
• Beside the role of ginger compounds as protectant against oxidative stress, they appeared
to have other immunoenhancement activity, notably in improving NK cell activity. This
improvement in NK cell activity had been observed in the male student studied receiving
ginger drink for 30 days
• analysis of ginger substances in the plasma reveal the presence of the assumed gingerol
group in the plasma of subjects drinking ginger, higher than that of the control group.
• Since NK cells are known to have specific activity in lysing mutated or infected cells,
the results of this research has shown the scientific support of the traditional beliefs that
ginger can improve body resistance to common cold.

ANTI KANKER GEL CINCAU HIJAU
(Cyclea barbata L.Miers)
Fransiska Rungkat-Zakaria,
Endang Prangdimurti, Edna Ananta, Albertus Seno Pandoyo
PENDAHULUAN
Secara tradisional, tanaman cincau hijau (Cyclea barbata L. Miers)
digunakan sebagai obat penurun panas, obat radang lambung, mual, dan
penurun tekanan darah tinggi. Minuman cincau merupakan produk olahan yang
berbentuk gel dan dibuat dari daun cincau hijau melalui proses extraksi dingin.
Beberapa laporan hasil penelitian menunjukkan bahwa tanaman cincau
mempunyai aktivitas sitotoksik dan antimalaria (Guinaudeau, 1993). Aktivitas
sitotoksik ini dihipotesiskan dapat menghambat proliferasi sel kanker atau sel
tumor di dalam tubuh..
Informasi ilmiah mengenai khasiat gel cincau hijau akan mendukung
perkembangan produk pangan fungsional yang berbentuk “healthy dessert”,
yang akhir-akhir ini amat digemari karena dapat mengimbangi konsumsi diet
mengandung lemak dan protein hewani tinggi dan kadar serat rendah.
Kanker merupakan penyakit yang diawali dari mutasi gen seluler, yang
diketahui sebagian besar disebabkan oleh faktor external seperti polutan
kimia baik pada makanan maupun lingkungan, virus, dan radiasi.
Mekanisme pencegahan mutasi gen dapat terjadi melalui aktifitas
antioxidan, perbaikan imunitas, atau sitotoksik (WCRF&AICR, 1997;
Zakaria-Rungkat et al., 2001)
METODA PENELITIAN
Extraksi air daun segar dengan aquades dilakukan secara manual karena
terbentuk gel yang kemudian didinginkan untuk memperoleh cairan sineresis.
Extrak air daun, akar dan batang dikeringbekukan.
Extrak etanol dan hexan dilakukan pada daun, akar dan batang keringbeku.
Extrak di tambahkan pada media kultur sel-sel kanker K562 (turunan sel
leukimia) dan Hela (turunan sel kanker servix) dan pada kultur sel limfosit
yang diisolasi dari darah tepi seorang mahasiswa sehat, dengan 5 tingkat
konsentrasi: C1 (1/2 C2); C2 (setara dengan konsumsi segelas minuman
cincau), C3 (2xC2); C4 (4xC2); C5 (8xC2).

KESIMPULAN

Minuman tradisional gel cincau hijau merupakan pangan
fungsional yang dapat mencegah terjadinya penyakit kanker
Extrak yang paling bersifat sitotoksik adalah extrak air akar
pada sel K562 (leukimia) yang menghambat kehidupan sel
sampai 61% dan pada sel Hela (kanker servix) sampai 31%
Rasa extrak akar yang amat pahit dapat merusak cita rasa
minuman gel cincau, sedang nilai ekonomisnya amat tinggi
Secara keseluruhan semua extrak pada konsentrasi setara
dengan satu gelas minuman gel cincau bersifat sitotoksik pada
sel K562 dan Hela. tetapi
Semua extrak pada konsentrasi setara dengan satu gelas
minuman gel cincau tidak bersifat sitotoksik pada sel limfosit
normal manusia

INTRODUCTION
Tumour growth:
oxidative stress, immunological disorder, malnutrition
Potential role for oxidative-induced injury in the cancer process
specifically during the promotion stage (Klaunig et al, 1998)
Sources of ROS :
from inflammatory cells (Cerutti and Trump, 1991)
A need in research to find suitable food for cancer patients
Green gel leaf Cyclea barbata L.Miers
common refreshing drink in South East Asian countries
known traditionally to have cooling and anti
inflammation effects in the body
This gel /extracts of the leaf had been reported to
have :
cytotoxic activity on cancer cell lines
non toxic on normal human lymphocyte cells
(Zakaria-Rungkat et al, 2001)
In this study, the leaves were processed to produce powder
products
which included all parts and fibres in the leaves

CONCLUSION
1. There is no difference in the latent period of the tumor growth in
mice. The leaf powder decrease tumor volume and tumor mass but
increase tumor necrotic tissue up to 3 times
2. Feeding leaf powder increased Tcell inspite of the tumor growth.
Slight increase in cytotoxicity in T and LP+T, indicate T cell
recognition of the tumor antigen
Prolonged tumor growth from 3 to 4 weeks markedly decrease
cells’ resistance to oxidative stress
3. The leaf powder increase SOD activity in mice but reduce
MDA in the liver Reduce liver catalase activity but did not
effect the other enzyme activity in the liver.
