- 1. 186Re-Etidronate
- [A synthetic compound containing the radioisotope rhenium 186 and a chelator, hydroxyethylidene diphosphonate (HEDP). Re-HEDP functions as a bone-seeking radiopharmaceutical when it is mixed with bioactive material, hydroxyapatite (calcium phosphate ceramic) via intravenous infusion. Re-186 is a beta emitter, with a short half life, which provides local effects with limited distribution to extramedullary bone marrow tissues. Re-HEDP can be used to treat pain associated with primary and metastatic bone lesions. ( NCI )] (UMLS (NCI) C0280809) =Organophosphorus Compound; Pharmacologic Substance
| - 4. Reexcision
- [A surgical procedure to remove the remaining abnormal tissues from the body, not completely removed in an earlier attempt. ( NCI )] (UMLS (NCI) C0184913) =Therapeutic or Preventive Procedure ;

- 2. RE-ENTRY OPERATION
- [ ] (UMLS (ICD9CM) C0190368) =Therapeutic or Preventive Procedure
| - 5. [R-(E,E)]-9-(3,3-Dimethyloxiranyl)-3,7-dimethyl-2,6-nonadienoic Acid Methyl Ester
- (UMLS (NCI) C0064183) =Organic Chemical

- 3. Reed-Sternberg cell
- [A type of cell that appears in people with Hodgkin's disease. The number of these cells increases as the disease advances. ( NCI )] (UMLS (NCI) C0085133) =Cell ;
| - 6.
- [An arbitrary unit for measurement the efficiency with which ingested provitamin A carotenoids (such as carotenes, xanthophylls, and compounds that arise from rearrangement of carotene I skeleton) are absorbed and converted to the active form of vitamin A in a mixed diet. The concept of retinol equivalent (RE) introduced by FAO/WHO Expert Group in 1967, is established on the following relationships among food sources of vitamin A based on carotenoids bioavailability and bioconversion data: one microgram of retinol is equal to one RE, one microgram of beta-carotene is equal to 0.167 RE, and one microgram of other pro-vitamin A carotenoids is equal to 0.084 RE. ( NCI )] (UMLS (NCI) C0556581) =Quantitative Concept
