  GRE阅读题目解析:糖尿病并发症

  P2

  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

  4. The author provides information that would answer which of the following questions?

  □A What is hyperglycemia?

  □B What is one cause of hyperglycemia?

  □C What are some of the organs that can be adversely affected by hyperglycemia?

  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
