Reactions of 2-methyl-1,4 naphthoquinone with human telomeric DNA and telomerase RNA ESR spin elimination has been used with 4-oxo-TEMPO as spin trap. The reactivities of 3VK3* with telomeric DNA, template of telomerase RNA and its L6-P6 region have been confirmed respectively. The results show that the reactivity of 3VK3* with polynucleotides is directly proportional to their G amount, and the one for reaction of 3VK3* with telomeric DNA is the highest in polynucleotides. 2.

Thirty patients with acute promyelocytic leukemia were observed between September 1977 and October 1985. Bleeding diathesis with petechiae or ecchymosis (80%) was the most common presenting symptom. Seventeen of 24 patients with pretreated coagulation studies were diagnosed to have disseminated intravascular coagulation. Six out of 11 patients died from intracranial hemorrhage after a mean of 2.5 days of hospitalization without any treatment. DIC was responsible for death in most cases. Induction therapy with anthracycline and cytosine arabinoside combined with prophylactic heparin infusion was carried out in the remaining 19 patients. Two patients were incompletely treated. Eight out of 17 patients achieved complete remission after a mean of 63 days following chemotherapy. The remission rate was 47%.

Both Fas and NO can lead chondrocyte apoptosis respectively and cause articular cartilage destruction. IGF-Ⅰ, TGF-β, bFGF, BMP and other growth factors are polypeptide agents that can influence cell activity by signal convection. They can accelerate chondrocyte proliferation and proteoglycan synthesis, play the local regulation action on formation and plerosis of bone and cartilage tissue by autocrine or paracrine.
