Kidneys

Bulky dialysis machines, which assume the kidney’s func­tion of blood cleansing with the help of a chemical solution and a filtering membrane are shrinking in size.

At the University of Utah, a wearable artificial kidney has been developed. An 8-pound, battery-powered unit strapped to the front of the body and periodically refilled with dialy­sis fluid from a portable 20-quart tank. It already is being used with success on a trial basis by about 100 patients yearly. Another kidney replacement system, is being used by about 5,000 patients in this country for dialysis at home, in rest rooms, in parks and even in cars. With a portable sack, the patient periodically pours a cleansing solution in and out of his abdomen through a surgically attached tube. Looking even further ahead, Dr. Eli Friedman of the Downstate Medical Center in Brooklyn says that “by the turn of the century, we may be able to use bacteria to convert nitrogen wastes into usable nutrients inside the patient’s in­testinal tract, completely substituting for the kidneys’ blood- cleansing function.”

Task 13. Choose the proper variant of words and phrases oat of the two given below to complete the sentences. Check your answer with the key at the end of the unit:

1. Thé size of dialysis machines becomes ... . 2. A wear­able artificial kidney is being used .... 3. A kidney replace­ment system is being used for ... .4. A patient pours a cleansing solution through ... . S: Bacteria may convert

nitrogen wastes into

  1. a components which will be digested; b components
