The complications frequently accompanying diabetes,
such as impairment of vision and of kidney function, are
now thought to result from the lack of continuous control
of blood glucose concentrations. The healthy pancreas,
in response to increases in blood glucose concentration,
releases small quantities of insulin throughout
the day and thereby maintains the concentration within
physiological limits (normoglycemia). But the diabetic
generally receives only one large dose daily. The
diabetic‘s blood glucose concentration can thus fluctuate
greatly during the interval between doses, and it has
been suggested that the complications result from the
periods of high concentrations of blood glucose
(hyperglycemia). Many investigators thus believe that
restoration of normoglycemia might halt the progression
of such complications and perhaps even reverse them.
For the following question, consider each of the
choices separately and select all that apply
5. According to the passage, widely spaced doses of
insulin can cause.
(A) reversal of normal kidney function
(B) delay in the onset of diabetes
(C) radical changes in the concentration of blood
glucose
(D) restoration of normoglyccmia
(E) marked variations in the islets of Langerhans
为什么我理解的是widely spaced doses 意思是一天中分散的剂量,等同于文中的
releases small quantities of insulin throughout the day啊啊然后就顺理成章的选了D
