| 영문 | nerve cell | 한글 | 신경세포 |
|---|---|---|---|
| 설명 | 신경세포는 올바른 신경전달을 위한 각 부분별로 나뉘어져 있다. 신경세포에서는 전해져오는 자극을 전기적인 신호로 바뀌어 보내거나 받게 된다. 이런 전기적인 현상은 각 신경세포내에 존재하는 각 이온채널(ion channel: ion이란 나트륨, 칼륨 등을 지칭하는 말들로써, 이들이 세포막에 의해 나뉘어질 때 생기는 전압차가 전기적 자극을 일으키고 유지하는데 결정적인 역할을 한다)들의 작용에 의해 이루어지게 된다. |

| 영문 | glia cell | 한글 | 아교세포 |
|---|---|---|---|
| 설명 | 신경세포 사이에서 그물구조를 이루며 이를 지지하는 조직. 신경아교세포는 신경모세포와 갈라진 아교모세포가 다시 여러 형태로 분화-성장한 것이다. 뇌실이나 척수중심관의 벽을 덮고 원주상 또는 입방형이며, 초기에는 유리면에 섬모가 있다. 대형세포는 별뇌실막세포는 아교세포라고 하며, 신경세포나 신경섬유 사이에 산재한다. 그 외에 희소돌기아교세포도 포함된다. |

| 영문 | reserve cell | 한글 | 예비세포 |
|---|---|---|---|
| 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. |

| plant-cane | A stalk or shoot of sugar cane of the first growth from the cutting. The growth of the second and following years is of inferior quality, and is called rattoon. Source: Websters Dictionary (01 Mar 1998) |
| plant casein | <plant biology> A prolamine, about 25% l-glutamic acid residues, found in oats (Avena) and in various legumes; considered highly nutritious. Synonym: legumin, plant casein. (05 Mar 2000) |

| plant dermatitis | See: dermatitis venenata. Primary irritant dermatitis, a frequently cumulative reaction of irritation on exposure of the skin to substances which are toxic to epidermal or connective tissue cells; lesions are usually erythematous and papular, but can be purulent or necrotic, depending on the nature of the toxic material applied.

| plant growth regulators | Any of the hormones produced naturally in plants and active in controlling growth and other functions. There are three primary classes: auxins, cytokinins, and gibberellins. (12 Dec 1998) |
| plant growth substances | <plant biology> Substances that, at low concentration, influence plant growth and differentiation. Formerly referred to as plant hormones or phytohormones, these terms are now suspect because some aspects of the hormone concept, notably action at a distance from the site of synthesis, do not necessarily apply in plants. Also called plant growth regulators. The major classes are absicisic acid, auxin, cytokinin, ethylene and gibberellin, others include steroid and phenol derivatives. (31 Dec 1997) |
| plant indican | 1. <chemistry> A glucoside obtained from woad (indigo plant) and other plants, as a yellow or light brown sirup. It has a nauseous bitter taste, a decomposes or drying. By the action of acids, ferments, etc, it breaks down into sugar and indigo. It is the source of natural indigo. 2. <physiology> An indigo-forming substance, found in urine, and other animal fluids, and convertible into red and blue indigo (urrhodin and uroglaucin). Chemically, it is indoxyl sulphate of potash, C8H6NSO4K, and is derived from the indol formed in the alimentary canal. Synonym: uroxanthin. See: Indigo. Source: Websters Dictionary (01 Mar 1998) |
| plant leaves | Expanded structures, usually green, of vascular plants, characteristically consisting of a bladelike expansion attached to a stem, and functioning as the principal organ of photosynthesis and transpiration. (12 Dec 1998) |
