His right arm and leg became weak again after the second stroke. But Miss [Donna Hazle] said, ''Movement is slowly returning to his right extremities.'' The second stroke left him unable to speak. ''He is not speaking yet,'' Miss Hazle said. The second test performed on Mr. [William J. Schroeder], the CAT scan, is a computer-enhanced X-ray that can show the brain tissue in much greater detail than the arteriogram. Two CAT scans taken earlier this week showed bleeding at two places on the left side of Mr. Schroeder's brain. One is at the base, the other is in the frontal area

The damage from William J. Schroeder's latest stroke has resulted from accumulations of blood in two areas of his brain and has created a ''severe neurological problem'' for the longest-living recipient of an artificial heart, hospital officials said yesterday. Donna Hazle, the hospital's director of public relations, described Mr. Schroeder as unable to speak but ''awake and responding to the presence of his wife, nurses and doctors.'' Nevertheless, Miss Hazle said, Mr. Schroeder's conditon ''seems to be gradually improving.''

The condition of William J. Schroeder, the longest-surviving recipient of an artificial heart, ''stabilized overnight'' and the bleeding in his brain apparently stopped after he suffered a stroke Monday, hospital officials said yesterday. It was Mr. Schroeder's second stroke since the mechanical heart was implanted 164 days ago. ''He is awake some of the time,'' Miss [Donna Hazle] said. ''He is breathing on his own at this time,'' Mr. Schroeder seemed to be aware of people in the room around him, according to Dr. Salb. Referring to the patient's wife, Dr. [J. P. Salb] said, ''Margaret said that when she was in there he squeezed her hand when she talked to him.''

Though Mr. [Jack C. Burcham]'s life was being supported by three artificial machines - a mechanical heart, a mechanical respirator and a dialysis machine - his doctors had issued an upbeat report earlier in the day. It said his kidney failure was ''resolving'' as a result of dialysis therapy. ''I was aware that there was a problem,'' Dr. [William C. DeVries] said. ''I thought that it was not serious at that time.'' Because the artificial heart is a rigid structure, the clots in Mr. Burcham's case did not compress the bottom chambers, or ventricles, and ''the usual early warning signs of cardiac tamponade were not present,'' Dr. [Allan M. Lansing] said

Mr. [Jack C. Burcham] had suffered from kidney problems, as have other artificial heart recipients, but he was the first to require kidney dialysis after the implant. Earlier in the day hospital officials had said that Mr. Burcham's kidney failure was ''resolving'' with the aid of dialysis

Death from the chronic wasting of AIDS is terrifying, often requires long hospital stays and is very expensive. And because scientists have so much to learn about the disease, people fear the unknown. Many AIDS victims have been shunned as lepers for fear that AIDS can be spread by casual contact. Another fear is that AIDS will soon race through heterosexuals the way it has through homosexuals, becoming the new syphilis in the New World. Mass education measures were used to encourage life style changes among homosexuals after AIDS was first recognized in that group. Because about one in two homosexual men in San Francisco have been exposed to the AIDS virus, tracing individual cases is not practical. Now advances in the scientific understanding of the nature of AIDS make necessary a more individualized approach to check the spread among heterosexuals, less than 1 percent of whom have been exposed to the virus, Dr. [Dean F. Echenberg] said. Under the San Francisco plan, a multidisciplinary team of epidemiologists, psychologists, sociologists and others will track down sexual contacts, give them AIDS tests, and offer counseling to those who are found to have been exposed to the AIDS virus and who thus are considered capable of passing the virus on to sexual contacts. The strategy, Dr. Echenberg said, ''rests on the assumption that no individual would want to unknowingly infect others.''

Murray P. Haydon, the third man to receive a permanent Jarvik-7 heart, appears to be a more fortunate victim of ARDS. Mr. Haydon's case was ''mild'' and not life-threatening, according to his surgeon, Dr. William C. DeVries. Even so, the damage from ARDS to the lungs poses a major therapeutic challenge. The lungs of an ARDS victim are stiff, heavy and almost airless. The microscopic-sized air sacs within the lungs collapse from a condition called pulmonary atelectasis. The lungs fill with water from another condition called pulmonary edema, and the lungs cannot extract enough oxygen for the body's needs. Though the underlying conditions that lead to ARDS often are known, the precise physiological factors that cause it remain a mystery. One leading theory is that ARDS results from the activation of white blood cells, which play important roles in the body's response to injury. In ARDS, white cells migrate to the lung and produce the biochemical changes that lead to the cascade of complications

Mrs. Schroeder said at a news conference before the move, ''We're going home in a sense - not our home, but we've lived in the Air Force for years, and home was wherever we were at.'' At the meeting in Utah earlier this week, Dr. [William C. DeVries] spoke of ''the tremendous fatigue factor'' that spouses had in caring for artificial heart recipients and ''the guilt feelings of maybe it would be better to have it over.'' Caring for her husband at home would have been ''a grave responsibility,'' Mrs. [Una Loy Clark] said, and the thought that a life-threatening problem could develop while she was away from him made her anxious. Nevertheless, she said, in the three years that Dr. Clark was incapacitated by his failing heart, she often thought about how she ''could have come home anytime and found him dead.''
