|---|---|
| replacement therapy | Therapy designed to compensate for a lack or deficiency arising from inadequate nutrition, from certain dysfunctions (e.g., glandular hyposecretion), or from losses (e.g., haemorrhage); replacement may be physiological or may entail administration of a substitute (e.g., a synthetic oestrogen in place of estradiol). (05 Mar 2000) |
| replacement vector | A cloning vector, such as a bacteriophage, in which some of the DNA of the vector can be replaced with foreign DNA. (09 Oct 1997) |
| hip replacement | Surgery to replace all or part of the hip joint with an artificial device that re-establishes normal hip joint motion. Indicated in cases of severe intractable degenerative arthritis (DJD). (27 Sep 1997) |
| hormone replacement therapy | In females, treatment with sex hormones for a number for reasons, including menopause, partial or full hysterectomy, or amenorrhoea.In women, treatment with sex hormones is indicated for a number of reasons, including menopause, partial or full hysterectomy, or amenorrhoea. After menopause, conjugated oestrogens, estradiol, or estrone sulfate are given to reduce pain during intercourse, limit blood vessel effects, and prevent loss of bone mass. After radical hysterectomy, conjugated oestrogens are given for similar reasons. After menopause or partial hysterectomy, progestin is administered at the same time to offset an increased risk of endometrial cancer. In some amenorrhoeas, oestrogen is given to restore menses; if the therapy is unsuccessful, this may indicate the presence of pathology, for instance, pituitary tumour. Benefits for postmenopausal women include a lowered risk of heart attack (oestrogen lowers LDL and raises HDL levels), and prevention of osteoporosis, since the rate of bone loss is directly linked to a drop in oestrogen levels (see perimenopause). Medical opinion about the hazard posed by such therapy remains divided. Some studies have indicated increased incidence of breast cancer; however, a comprehensive 1992 review of the literature contradicted this finding. (05 Mar 2000) |
| oestrogen replacement therapy | <endocrinology, gynaecology> The use of oestrogenic substances in postmenopausal or other oestrogen-deficient women to alleviate effects of hormone deficiency, such as vasomotor symptoms, dyspareunia, and progressive development of osteoporosis. (12 Dec 1998) |
| ossicular replacement | Surgical insertion of an implant to replace one or more of the ear ossicles. (12 Dec 1998) |
| energy replacement time | <radiobiology> Time required for a plasma to lose (via radiation or other loss mechanisms) an amount of energy equal to its average kinetic energy. (09 Oct 1997) |
| enzyme replacement therapy | A type of medical treatment for patients who lack an important enzyme, the missing enzyme is injected into the patient. (09 Oct 1997) |
| anterior knee region | The anterior region of the knee. Synonym: regio genus anterior. (05 Mar 2000) |
| arthroscopic knee repair | <orthopaedics> A fibreoptic procedure, known as arthroscopy, is used in the surgical repair of any of several knee ligaments including the anterior cruciate ligament (ACL), lateral or medial meniscus, lateral collateral or medial collateral ligament. Recovery from this procedure is based largely on the ligament repaired and can be highly variable. (27 Sep 1997) |

| articular vascular network of knee | An arterial network over the front and sides of the knee, formed by branches of the descending genicular artery, of the five genicular arteries from the popliteal, of the anterior tibial recurrent, and of the fibular circumflex branch of the posterior tibial.
