(i ) Certain of the advanced cases of cancer and particularly those with a
superadded infection showed a hyperglycemis and
a delayed blood sugar fall of the mild diabetic
type following the ingestion of 50 gms.
of glucose. In certain cases also, there
appeared to be a raised renal threshold for
sugar.
(ii) In advanced tuberculosis the fasting
blood sugar is raised, end the sugar tolerance
tests show a response similar to that shown by
a mild case of diabetes. The renal threshold
for sugar is also raised.
(iii) The fasting blood sugar tends to
rise with advancing age.
(iv) The fasting blood sugar level in
pregnancy is not raised beyond the normal
limits. With labour the percentage blood
sugar gradually rises to varying levels up
to the end of the second stage . During the
early days of the puerperium a hyperglycemia
exists. The mechanism controlling this
hyperglycemia is not known. It is not due
to an excessive secretion of the pituitary
gland.
(v) This hyperglycemia of the puerperium
is offered as an explanatory hypothesis of
the rapid development of tuberculosis and of
the tendency for innocent tumours to become
malignant following labour. Also of the
lowered resistance to general infections and
especially streptococcal infections found
during the puerperium.
(vi) It is also offered as bearing some
relationship to the absence of symptoms following
repeated injections of pituitrin in
pregnant women and women in the puerperium
