| 영문 | signal transduction | 한글 | 신호전달 |
|---|---|---|---|
| 설명 | 세포에 있어 수용체의 신호수용에서 기능발현에 이르기까지의 정보전달. 지용성의 스테로이드호르몬이나 비타민 등을 제외하고 수용성호르몬, 신경화학물질이나 세포증식인자 등은 세포막상에 특이적인 수용체를 갖고 정보를 세포내로 전하여 다양한 세포반응을 일으킨다. |

| 영문 | visual acuity | 한글 | 시력 |
|---|---|---|---|
| 설명 | 눈을 가지고 정확히 보아 식별할 수 있는 능력이다. 시력표를 이용하여 측정한다. 5m밖에서 시력표를 보아 2/3이상 읽을 수 있는 최대시력을 시력으로 정한다. 정확한 시력검사는 산동제를 투여하여 눈의 조절을 막고, 검안경으로 검사해야 한다. |

| 영문 | visual field test | 한글 | 시야검사 |
|---|---|---|---|
| 설명 | 눈을 한곳에 고정시킨 채, 관찰할 수 있는 주변공간을 시야라 한다. 시야를 검사하는 가장 간단한 방법은 대면검사(confronting test)이다. 이것은 피검사자의 눈을 검사자의 눈에 맞추어 보도록 하여 눈을 고정시킨채, 검사자가 손가락끝을 위쪽, 아래쪽, 왼쪽, 오른쪽, 그리고 비스듬히 경사진 곳 등으로 옮겨보아 피검사자가 관찰할 수 있는지 여부를 정하는 검사법이다. 이보다 정확한 검사법은 자동식 컴퓨터시야검사법이 있다. 대개, 눈자체의 이상이 있어도 시야검사에서 이상이 나오지만, 이외 뇌의 이상으로 시각의 형성경로에 이상이 있어도 역시 이상소견을 보인다. |

| abortive transduction | Transduction in which the genetic fragment from the donor bacterium is not integrated in the genome of the recipient bacterium, and, when the latter divides, is transmitted to only one of the daughter cells. (05 Mar 2000) |
|---|---|
| general transduction | Transduction in which the transducing bacteriophage is able to transfer any gene of the donor bacterium. (05 Mar 2000) |
| complete transduction | Transduction in which the transferred genetic fragment is fully integrated in the genome of the recipient bacterium. (05 Mar 2000) |
| high frequency transduction | Specialised transduction in which the donor bacterium contains not only the transducing, defective probacteriophage but also nondefective prophage that serves as "helper" virus, enabling most of the defective prophage particles to develop sufficiently to function as transducing agents. (05 Mar 2000) |
| signal transduction | The cascade of processes by which an extracellular signal (typically a hormone or neurotransmitter) interacts with a receptor at the cell surface, causing a change in the level of a second messenger for example calcium or cyclic AMP) and ultimately effects a change in the cells functioning (for example: triggering glucose uptake or initiating cell division). Can also be applied to sensory signal transduction, for example of light at photoreceptors. (18 Nov 1997) |
| specialised transduction | Transduction in which the bacteriophage strain is able to transfer only some, or only one, of the donor bacterium genes. Synonym: specific transduction. (05 Mar 2000) |
| specific transduction | Transduction in which the bacteriophage strain is able to transfer only some, or only one, of the donor bacterium genes. Synonym: specific transduction. (05 Mar 2000) |
| transduction | 1. <molecular biology> The transfer of a gene from one bacterium to another by a bacteriophage. In generalised transduction any gene may be transferred as a result of accidental incorporation during phage packaging. In specialised transduction only specific genes can be transferred, as a result of improper recombination out of the host chromosome of the prophage of a lysogenic phage. Transduction is an infrequent event but transducing phages have proved useful in the genetic analysis of bacteria. 2. <biology, physics> The conversion of a signal from one form to another. For example: various types of sensory cells convert or transduce light, pressure, chemicals, etc. Into nerve impulses and the binding of many hormones to receptors at the cell surface is transduced into an increase in cAMP within the cell. (17 Mar 1998) |
| transduction, genetic | Transfer of bacterial DNA by phages from the infected bacterium in which the DNA originates to another bacterium. (12 Dec 1998) |
| low frequency transduction | Specialised transduction in which only a small portion of the prophage particles, because of their defectiveness, are able to develop sufficiently to serve as effective transducing agents. (05 Mar 2000) |
| accessory visual apparatus | The eyelids, with lashes and eyebrows, lacrimal apparatus, conjunctival sac, and extrinsic muscles of the eyeball. Synonym: organa oculi accessoria, accessory organs, accessory visual apparatus, adnexa oculi, appendages of eye. (05 Mar 2000) |
| Bender Visual Motor Gestalt test | <psychology> A psychological test used by neurologists and clinical psychologists to measure a person's ability to visually copy a set of geometric designs. It consists of nine geometric designs on cards. The subject is asked to redraw them from memory after each one is presented individually. It is useful for measuring visuospatial and visuomotor coordination to detect brain damage. Synonym: Bender Visual Motor Gestalt test. (14 Aug 2000) |
| Broca's visual plane | A plane drawn through the visual axes of each eye. (05 Mar 2000) |
| receptor, visual | The layer of rods and cones, the visual cells, of the retina. (12 Dec 1998) |
| pattern recognition, visual | Visually perceived characters, shapes, displays, or designs. (12 Dec 1998) |
