| 영문 | acquired immunodeficiency syndrome | 한글 | 후천면역결핍증후군, 에이즈 |
|---|---|---|---|
| 설명 | 인간면역결핍바이러스(HIV)에 의하여 면역 세포가 파괴됨으로써 인체의 면역능력이 극도로 저하되어 병원체에 대하여 무방비 상태에 이르는 병. 에이즈 바이러스의 감염으로 생기며, 1981년 미국에서 처음 보고되었다. 최초 감염으로부터 증상이 나타나기까지는 평균 10년 정도 걸리며 사망률이 대단히 높다. 성적 접촉, 오염 주사기 사용, 오염 혈액 및 혈액 제제 사용, 에이즈 산모로부터 수직감염 따위에 의하여 감염된다. 감염 후 일과성으로 감기와 같은 증상을 보이며 바이러스혈증으로 되지만 바이러스는 감소되고 6~8주 후에는 항체가 양성으로 된다. 6~10년 정도의 무증후성 보균기간을 지나서 에이즈관련증후군(AIDS related syndrome)으로 된다. 저항력의 감소, 림프절비대, 체중감소, 발열, 만성설사가 이어진다. 그 후 에이즈로 되며, 폐포자충폐렴 등의 원충병, 칸디다 등의 진균증, 헤르페스바이러스군 등의 기회감염이 이어진다. 또한 카포시육종, 림프종 등을 병발해서 사망한다. 바이러스의 뇌조직내 증식으로 치매를 일으킬 수도 있다. HIV-1은 10년간에 사망률이 90%, HIV-2는 10%이다. |

| lenticular loop | The pallidal efferent fibres curving around the medial border of the internal capsule. Synonym: ansa lenticularis, lenticular ansa. (05 Mar 2000) |
| loop | 1. A fold or doubling of a thread, cord, rope, etc, through which another thread, cord, etc, can be passed, or which a hook can be hooked into; an eye, as of metal; a staple; a noose; a bight. "That the probation bear no hinge, nor loop To hang a doubt on." (Shak) 2. A small, narrow opening; a loophole. "And stop all sight-holes, every loop from whence The eye of Reason may pry in upon us." (Shak) 3. A curve of any kind in the form of a loop. 4. A wire forming part of a main circuit and returning to the point from which it starts. 5. <physics> The portion of a vibrating string, air column, etc, between two nodes; called also ventral segment. Loop knot, a single knot tied in a doubled cord, etc. So as to leave a loop beyond the knot. Origin: Cf. Ir. & Gael. Lub loop, noose, fold, thong, bend, lub to bend, incline.

| loop bioreactors | Bioreactors in which the fermenting material is cycled between a bulk tank and a smaller tank or loop of pipes. The circulation helps mix the materials and ensures that gas injected into the fermenter is well distributed. (14 Nov 1997) |
| loop diuretic | A class of diuretic agents (e.g., furosemide, ethacrynic acid) that act by inhibiting reabsorption of sodium and chloride, not only in the proximal and distal tubules but also in Henle's loop. (05 Mar 2000) |
| loop electrocautery excision procedure | Electrocautery excisional biopsy of abnormal cervical tissue. (05 Mar 2000) |
| loop excision | A diagnostic and therapeutic gynecological surgical technique for removing dysplastic cells from the cervix. In this office procedure conducted with the aid of colposcopy, a small wire loop is used to excise visible patches of cervical intraepithelial neoplasia. Like cauterization, cryosurgery, and CO2 laser procedures, loop excision can be done with local anaesthetic, and is an uncomplicated, relatively inexpensive way of removing dysplastic cells; in addition, it provides material for biopsy. It is not advised for cases of severe dysplasia or carcinoma in situ, which are better addressed by cervical conization, an inpatient procedure. Synonym: loop resection. (05 Mar 2000) |
| loop of henle | A u-shaped turn in the medullary portion of a renal tubule, with a descending limb from the proximal convoluted tubule and an ascending limb to the distal convoluted tubule. (12 Dec 1998) |
| loop of hypoglossal nerve | A loop in the cervical plexus consisting of fibres from the first three cervical nerves. Fibres from a loop between the C-1 and C-2 spinal nerves accompany the hypoglossal nerve for a short distance, leaving it as the superior root of the ansa cervicalis. Fibres from a loop between the C-2 and C-3 spinal nerves form the inferior root of the ansa cervicalis. Most commonly, the roots merge, forming the ansa cervicalis, which gives rise to branches innervating infrahyoid muscles. Synonym: cervical loop, loop of hypoglossal nerve. (05 Mar 2000) |

| Aarskog-Scott syndrome | A syndrome of ocular hypertelorism, anteverted nostrils, broad upper lip, saddle-bag scrotum, and laxity of ligaments resulting in genu recurvatum, flat feet, and hyperextensible fingers; X-linked and autosomal dominant forms. Synonym: Aarskog-Scott syndrome. (05 Mar 2000) |
| Aarskog syndrome | <syndrome> Grier et al. (1983) reported father and 2 sons with typical Aarskog syndrome, including short stature, hypertelorism, and shawl scrotum. They tabulated the findings in 82 previous cases. X-linked recessive inheritance has been repeatedly suggested. The family reported by Welch (1974) had affected males in 3 consecutive generations. Thus, there is either genetic heterogeneity or this is an autosomal dominant with strong sex-influence and possibly ascertainment bias resulting from use of the shawl scrotum as a main criterion. Stretchable skin was present in the cases of Grier et al. (1983). Teebi et al. (1993) reported the case of an affected mother and 4 sons (including a pair of monozygotic twins) by 2 different husbands. They suggested that the manifestations were as severe in the mother as in the sons and that this suggested autosomal dominant inheritance. Actually, the mother seemed less severely affected, compatible with X-linked inheritance. Clinical signs: Mild to moderate short stature,normocephaly, Widow's peak hair, maxillary hypoplasia, broad nasal bridge, anteverted nostrils, long philtrum, broad upper lip, curved linear dimple below the lower lip, hypertelorism, ptosis, down-slanted palpebral fissures, ophthalmoplegia, strabismus, hyperopic astigmatism, large cornea, floppy ears, lop-ears,cleft lip/palate, shawl scrotum, saddle-bag scrotum, cryptorchidism, brachydactyly, digital contractures, clinodactyly, mild syndactyly, transverse palmar crease, lymphoedema of the feet, ligamentous laxity, osteochondritis dissecans, proximal finger joint hyperextensibility, flexed distal finger joints, genu recurvatum, flat feet, stretchable skin, cervical spine hypermobility, odontoid anomaly, macrocytic anaemia, hemochromatosis, hepatomegaly, portal cirrhosis, imperforate anus, rectoperineal fistula, interstitial pulmonary disease, sternal deformity. Inheritance: Sex-influenced autosomal dominant form, also X-linked form. (05 Aug 1998) |
| abdominal muscle deficiency syndrome | <syndrome> Congenital absence (partial or complete) of abdominal muscles, in which the outline of the intestines is visible through the protruding abdominal wall; in males, genitourinary anomalies (urinary tract dilation and cryptorchidism) are also found; genetics unclear. (05 Mar 2000) |
| abstinence syndrome | <syndrome> A constellation of physiologic changes undergone by persons or animals who have become physically dependent on a drug or chemical due to prolonged use at elevated doses, but who are abruptly deprived of that substance. The abstinence syndrome varies with the drug to which dependence has developed. Generally the effects observed are in an opposite direction from those produced by the drug; e.g., the withdrawal syndrome from central nervous system depressants such as barbiturates and benzodiazepines consists of insomnia, restlessness, tremulousness, hallucinations, and, in the extreme, tonic-clonic convulsions which may prove fatal. The onset time and severity of the abstinence syndrome depend upon how rapidly the drug disappears from the body. (05 Mar 2000) |
