During the next few days, however, the Sandinistas gave less cordial signals. First, they confiscated the coffee farms of three opposition members.

...million immune cells from the liver and thymus of two aborted fetuses, and injected the material into David's umbilical cord. After he was born, David received an injection of more cells. Blood tests indicate that the transplanted cells have multiplied in David's liver, spleen and bone marrow -- signs that his immune system may become normal...
...effect a cure, doctors would remove bone-marrow cells from a patient and expose them to a retrovirus* engineered to carry correctly functioning versions of the patient's faulty gene. When the retrovirus invaded a marrow cell, it would insert itself into the cellular DNA, as retroviruses are wont to do, carrying the good gene with it. Reimplanted in the marrow, the altered marrow cells would take hold and multiply, churning out the previously lacking protein and curing the thalassemia patient...
...possibilities for gene therapy will be limited for the near future. If gene transplants are performed on tissue cells -- bone-marrow cells, for instance -- the altered genes will die with the patient; they cannot be passed on to any children the patient might subsequently have. Someday, however, it may be possible to change genes in germ cells, which give rise to sperm or eggs. If that feat is accomplished, the new genes would be transmitted to one generation after another...
...Soviet Union to correct dwarfism, which Dr. Victor Frankel, president and head of orthopedic surgery at Manhattan's Hospital for Joint Diseases, intended to introduce into the U. S. The shin, thigh and upper-arm bones would be cut clear through, leaving only the bone cavity and the marrow intact. A special frame, with steel pins going through the bone on each side of the cut, would keep the pieces in line and allow them to be pulled apart a millimeter a day. New bone would form and fill in the gap, adding at least 7 in. to the shin...
