1)Stem cells taken from bone marrow can
revitalise non-functional heart muscles—-
AIIMS(All India Institute of Medical Science,
New Delhi, India.) shows how.
2)Man’s best friend(=trained dog) sniffs out
cancer.They detect lung,breast and liver cancer
in breath; bladder(kidney)cancer in urine and
melanoma on skin.The tumours gave off chemicals
for dogs to smell cancer–researchers found.
Historically doctors have used smell to make
diagnosis.Hippocrates described the fruity odour
of diabetes in the breath and the musty odour of
liver disease. The Yellow Emperor’s ”Classic of
Internal Medicine” counselled diagnosing lung
cancer by having patients spit into a fire; bacteria
laden sputum smells putrid.Dog tests are cheap
and useful in poor countries.Dogs however do not
replace X-rays,CTscans, fibre-optic scopes,
mammograms, Pap smears and other cancer
screens. Also most tests cannot tell a tumour
from a benign lump, as dogs apparently can.
