| 영문 | nucleic acid | 한글 | 핵산 |
|---|---|---|---|
| 설명 | 염기, 당, 인산으로 이루어진 뉴클레오티드가 긴 사슬 모양으로 중합된 고분자 물질. 유전이나 단백질 합성을 지배하는 중요한 물질로, 생물의 증식을 비롯한 생명 활동 유지에 중요한 작용을 한다. 구성 당인 오탄당이 리보오스인 리보핵산과 디옥시리보오스인 디옥시리보 핵산으로 나뉜다. 펜토스로서 리보스나 데옥시리보스 어느 한쪽만을 포함하며 전자를 리보핵산(RNA), 후자를 데옥시리보핵산(deoxyribonucleic acid, DNA)이라 부른다. 모두 4종류의 유기염기에 의해 특징지어지며 아데닌, 구아닌 및 시토신은 양자에 공통이다. 티민은 DNA에, 우라실은 RNA에 포함된다. DNA는 주로 핵에 존재하며 형질유전에 그리고 RNA는 세포질속에서 단백질 합성에 관여한다. 섭취된 핵산은 소화관에서 구성분자로까지 가수분해되어 흡수된다. |

| oral candidiasis | <gastroenterology, microbiology, oncology> Infection with a fungus of the genus Candida. It is usually a superficial infection of the moist cutaneous areas of the body and is generally caused by Candida albicans, it most commonly involves the skin (dermatocandidiasis), oral mucous membranes (oral candidiasis), respiratory tract (bronchocandidiasis) and vagina (vaginal candidiasis or thrush). Rarely there is a systemic infection or endocarditis. Oral candidiasis: describes a fungal (yeast) infection of the oral cavity due to Candida. It is common in infants, diabetics or those on chemotherapy and is well recognised in patients with HIV infection and AIDS. Oesophageal candidiasis: Infection of the oesophagus by the yeast-like fungus Candidal albicans. Usually occurs in the immunocompromised individual (AIDS or following chemotherapy). Oral candidiasis is a predisposing factor but oesophageal involvement can occur without evidence of infection in the oral cavity. Symptoms include difficulty swallowing, pain on swallowing and oral lesions. Diagnosis is made using endoscopy. Treatment is with antifungal agents such as ketoconazole or fluconazole. Synonym: moniliasis, candidosis, oidiomycosis, blastodendriosis. (16 Dec 1997) |
| oral cavity | The region consisting of the vestibulum oris, the narrow cleft between the lips and cheeks, and the teeth and gums, and the cavitas oris propria. Synonym: cavitas oris, cavum oris, mouth. (05 Mar 2000) |
| oral cavity proper | The space between the dental arches, limited posteriorly by the isthmus of the fauces (palatoglossal arch). Synonym: cavitas oris propria. (05 Mar 2000) |
| oral cholecystogram | <radiology> Dose: 6 x 0.5 gram tablets after evening meal, peak opacification in 14-19 hrs. (13-35% excreted in urine) patient selection: bilirubin less than 5mg% (unless secondary to haemolysis), contraindicated in serious liver disease, relative contraindications in peritonitis, postoperative ileus, acute pancreatitis nonvisualization of gallbladder, cholecytectomy, obstruction of cystic duct, chronic cholecystitis, anomolous position of gall bladder, extrabiliary causes, fasting state, failure to reach absorptive surface of bowel (e.g. Malabsorption), deficiency of bile salts (Crohn disease, surgical resection of TI, liver disease, cholestyramine therapy, abnormal communication between biliary and GI tract) (12 Dec 1998) |

| oral epithelial nevus | An autosomal dominant condition of the oral cavity characterised by soft, white or opalescent, thickened and corrugated folds of mucous membrane; other mucosal sites are occasionally involved simultaneously. Synonym: familial white folded dysplasia, oral epithelial nevus. (05 Mar 2000) |
| oral (erosive) lichen planus | Oral manifestations of lichen planus characterised by white striae (Wickham's striae) of the oral mucous membrane and sometimes associated with ulceration; patients may or may not exhibit a history of cutaneous lichen planus. (05 Mar 2000) |
