|---|---|---|---|
| 설명 | 일반적으로 상피조직에서 이미 있던 상피세포가 손상을 받아 사멸하면 매꿔지는 그 밑에 있는 미분화세포 예를 들면, 기관지 내표면을 덮는 중층 원주 상피의 기저에 있는 작은 미분화 상피 세포. |

| 영문 | stem cell | 한글 | 줄기세포, 간세포 |
|---|---|---|---|
| 설명 | 자기 복제를 하여 자신을 존속시키면서 한편으로는 증식과 분화를 하여 새로운 세포를 형성하는 세포로서 조혈줄기세포가 대표적이다. 조혈줄기세포는 골수에 있는 세포로서 모든 혈구세포가 여기에서 분화되어 발생한다. |

| 영문 | renal cell carcinoma | 한글 | 콩팥세포암종 |
|---|---|---|---|
| 설명 | 콩팥에 생긴 원시콩팥조직에서 발생한 암. 주로 원시세뇨관조직에서 발생한다. 대표적인 세포조직형은 염색시 세포질이 맑게 비어보이는 맑은세포암종이다. 치료는 수술과 항암화학요법이며 아주 드물지만 저절로 낫는 경우도 있는 것으로 보고되어 있다. |

| 영문 | squamous cell carcinoma | 한글 | 편평세포암종 |
|---|---|---|---|
| 설명 | 편평세포 기원의 암으로서, 편평세포가 있는 어떤 곳에서든 발생가능함. 따라서 식도암, 피부암, 폐암, 자궁암 등이 여기에 해당된다. 특히 피부암은 많은 자외선조사에 의해 생기는 광선각화증에서 발생가능하다. 병리조직학적 특성으로서 각질을 생성한다. |

| mass movement | Forcible peristaltic movements of short duration, occurring only three or four times a day, which move the contents of the large intestine from one division to the next, as from the ascending to the transverse colon. Synonym: mass movement. (05 Mar 2000) |
|---|---|
| mass number | The mass of the atom of a particular isotope relative to hydrogen-1 (or to 1/12 the mass of carbon-12), generally very close to the whole number represented by the sum of the protons and neutrons in the atomic nucleus of the isotope (indicated in the name or symbol of the isotope; e.g., oxygen-16, 16O); not to be confused with the atomic weight of an element, which may include a number of isotopes in natural proportion. (05 Mar 2000) |
| mass peristalsis | Forcible peristaltic movements of short duration, occurring only three or four times a day, which move the contents of the large intestine from one division to the next, as from the ascending to the transverse colon. Synonym: mass movement. (05 Mar 2000) |
| mass reflex | In cases of gross injury to the spinal cord, as the stage of reflex activity follows the primary flaccidity of the shock, a condition arises in which a strong stimulus to any part of one of the paralysed limbs will be followed by contraction of the hip, knee, and ankle of the same side and often, when the stimulus is applied to the middle line of the body, of both sides, as well as of the abdominal wall, and even evacuation of the bladder and sweating over an area corresponding to the level of the lesion. (05 Mar 2000) |
| mass screening | Organised periodic procedures performed on large groups of people for the purpose of detecting disease. (12 Dec 1998) |
| mass spectrograph | An instrument that subjects charged and accelerated ions (atomic or molecular) to a magnetic field that imparts a curved path that differs for each mass-to-charge ratio, thus separating individual species; used in detecting and assaying isotopic ratios and in molecular structure determinations. (05 Mar 2000) |
| mass stopping power | <physics> The mass stopping power (S/r) of a material for charged particles is the quotient dEs by the product of dl and r, where dEs is the average energy lost by a charged particle of specified energy in traversing a path length dl and r is the density of the medium. (16 Dec 1997) |
| MASS syndrome | <syndrome> A syndrome closely resembling both the Marfan's syndrome and the Barlow syndrome. However, no dislocation of the lenses or aneurysmal changes occur in the aorta, and the mitral valve prolapse is by no means invariable. at present it has been assigned no separate OMIM number, but shares that of the Barlow syndrome. Origin: mitral valve prolapse, aortic anomalies, skeletal changes, and skin changes. (05 Mar 2000) |
| parotid gland mass | <radiology> Pleomorphic adenoma, sialocele, adenoid cystic carcinoma, adenocarcinoma, lymphoma, lymph node, abscess, metastasis (12 Dec 1998) |
| relative molecular mass | The sum of the atomic weight's of all the atoms constituting a molecule; the mass of a molecule relative to the mass of a standard atom, now 12C (taken as 12.000). Relative molecular mass (Mr) is the mass relative to the dalton and has no units. See: atomic weight. Synonym: molecular mass, molecular weight ratio, relative molecular mass. (05 Mar 2000) |
| middle ear mass | <radiology> Glomus tumour (multiple in 10%; 8% malignant), glomus tympanicum, from cochlear promontory, seldom erodes bone, glomus jugulare, invasion of middle ear from below, destruction of bony roof of jugular fossa and bony spur separating vein from carotid artery, abberant carotid artery (no bony margin), enlarged jugular bulb (dehiscent bony covering), cholesteatoma, rhabdomyosarcoma (orbit greater than nasopharynx greater than ear), adenocarcinoma (rare) (12 Dec 1998) |
| middle mediastinal mass | <radiology> Mnemonic: not VD, 90% malignant, Nodes, tumour (metastasis, lymphoma/leukaemia), infection, inhalational disease, Castleman disease, Tumour, primary lung, trachea, oesophagus carcinoma, Vascular, aneurysm, haematoma, Duplication cyst, bronchogenic, enteric, neurenteric (12 Dec 1998) |
| molar mass | See: molecular weight. (05 Mar 2000) |
| molecular mass | The sum of the atomic weight's of all the atoms constituting a molecule; the mass of a molecule relative to the mass of a standard atom, now 12C (taken as 12.000). Relative molecular mass (Mr) is the mass relative to the dalton and has no units. See: atomic weight. Synonym: molecular mass, molecular weight ratio, relative molecular mass. (05 Mar 2000) |
| pill mass | The mixture of drug(s), excipients, diluents and binders with a suitable amount of liquid to form a plastic mass which can be rolled into a long rod and cut into the appropriate number of units for pills to be rolled from. Synonym: pill mass. (05 Mar 2000) |
