|---|---|---|---|
| 설명 | 산소운반과 활용 과정에 장애를 발생하여, 동맥혈 산소함량(PaO2)이 감소하며, 조직 속의 산소가 정상치 이하로 감소한 상태. 대별하면 ① 저산소성저산소증, ② 빈혈저산소증, ③ 울혈저산소증, ④ 조직독성저산소증, ⑤ 수용성 저산소증을 분류된다. 초기증상은 의식혼란, 두통, 어지럼증, 구역, 가쁜 호흡, 빠른 맥 등으로, 증상이 진행하면 청색증(혈증 환원 Hb 가 5g/100mL 이상), 의식소실, 경련, 느린맥, 부정맥, 호흡억제, 심장정지에 이른다. 산소요법, 기계적 인공호흡을 실시한다. 그 종류를 원인별로 분류하면 다음과 같다. ① 저산소성저산소증(hypoxic hypoxia): 동맥혈의 산소분압이 감소되어 초래된 저산소증으로 흡입 공기 중의 산소 농도가 감소한 경우, 호흡 중추억제-기도폐쇄-호흡근마비 등 폐포환기가 감소한 경우, 무기폐-폐렴-폐부종 등 폐포에서의 가스 교환이 부적절하여 일어나는 경우, 고열-신진대사항진 등 조직의 산소 소모가 증가하여 일어나는 경우, 이산화질호(N2O)를 이용한 전신마취 후에 드물게 나타나는 확산성 저산소증 등에 의해 발생할 수 있다. ② 빈혈저산소증(anemic hypoxia) : 혈색소가 정상 이하로 감소한 경우, 일산화 탄소중독처럼 혈색소가 산소를 운반할 수 없는 경우에 나타나는 저산소증으로서 산소분압은 정상 범위 내에 있으나 동맥혈의 산소 함량이 크게 감소되어 있는 경우가 대부분이다. ③ 울혈저산소증(stagnant hypoxia) : 동맥혈의 산소분압은 정상이나 조직의 혈액순환이 장애를 받아 나타나는 저산소증으로 심박출량이 감소하여 오는 경우도 있고, 색전증-외상-혈관수축-정맥폐쇄 등에 의해 발생할 수도 있다. ④ 조직독성저산소증(histotoxic hypoxia) : 사립체의 산소 이용률이 낮아진 경우에 나타난다. 혈관 확장제를 과량 사용하게 되면 세포 내 효소의 독성에 의해 저산소증이 올 수 있다. |

| hypoxaemia test | A test for coronary insufficiency; the patient breathes a mixture of 10% oxygen and 90% nitrogen; if anginal pain or electrocardiographic abnormalities are induced, the test is positive. Synonym: hypoxaemia test. (05 Mar 2000) |
| hypoxanthin | <physiology> A crystalline, nitrogenous substance, closely related to xanthin and uric acid, widely distributed through the animal body, but especially in muscle tissue. Synonym: sarcin, sarkin. Origin: Pref. Hypo- + xanthin. Source: Websters Dictionary (01 Mar 1998) |
| hypoxanthine | Purine base present in inosine monophosphate (IMP) from which adenosine monophosphate (AMP) and guanosine monophosphate (GMP) are made. The product of deamination of adenine, 6 hydroxy purine. (18 Nov 1997) |
| hypoxanthine guanine phosphoribosyltransferase | <enzyme> An enzyme that catalyses the conversion of 5-phosphoribosyl-1-pyrophosphate and hypoxanthine, guanine, or 6-mercaptopurine to the corresponding 5'-mononucleotides and pyrophosphate. The enzyme is important in purine biosynthesis as well as central nervous system functions. Complete lack of enzyme activity is associated with the lesch-nyhan syndrome, while partial deficiency results in overproduction of uric acid. Chemical name: IMP:pyrophosphate phospho-D-ribosyltransferase Registry number: EC 2.4.2.8 (12 Dec 1998) |
| hypoxanthine guanine phosphoribosyltransferase deficiency | A sex-linked inherited metabolic disorder; complete deficiency results in Lesch-Nyhan syndrome; incomplete deficiency is associated with acute gouty arthritis and renal stones. (05 Mar 2000) |
| hypoxanthine oxidase | <enzyme> Dehydrogenases involved in conversion of hypoxanthine to xanthine and xanthine to uric acid, as the final catabolism of purines. Deficient in the human disease xanthinuria. (18 Nov 1997) |
| hypoxanthine phosphoribosyltransferase | <enzyme> An enzyme that catalyses the conversion of 5-phosphoribosyl-1-pyrophosphate and hypoxanthine, guanine, or 6-mercaptopurine to the corresponding 5'-mononucleotides and pyrophosphate.

| hypoxanthine-aminopterin-thymine medium | A type of agar growth medium (a selective medium) which is used to select for cells that are able to make their nucleic acids out of hypoxanthine and/or thymine. All cells are prevented from making nucleotides by any other means (due to the presence of aminopterin or other drugs in the medium), so cells which are unable to use hypoxanthine and/or thymine to do this will not grow, multiply, and become visible colonies. This leaves the cells which are being selected for. (09 Oct 1997) |
| hypoxanthine-guanine phosphoribosyl tranferase marker | The gene which codes for the enzyme hypoxanthine-guanine phosphoribosyl transferase. It is a selectable marker because cells which have a defective version of this gene are resistant to poisoning by toxic purine derivatives which result from the metabolic pathway that the HGPRT enzyme catalyses. (The purine derivatives are toxic because they incorporate into DNA as a result of the HGPRT enzyme's actions). Because the defective gene cannot produce the enzyme, no toxic purine derivatives are produced, the gene can therefore be selected for. (09 Oct 1997) |
| hypoxanthine-guanine phosphoribosyl transferase | <enzyme> An enzyme which plays an important role in the making of ATP and GTP from guanine -- the only way guanine, adenine, or other purine molecules are able to become part of nucleic acids. Biologists study gene action via the incorporation of modified nitrogenous bases into DNA by manipulating the metabolic role which this enzyme plays. Similarly, the enzyme thymidine kinase is used for the same purpose by biologists because it fills the same important and unique role for the pyrimidines (thymine, cytosine, uracil, etc.). Acronym: HGPRT (09 Oct 1997) |
| hypoxanthine-guanine-xanthine phosphoribosyltransferase | <enzyme> From tritrichomonas foetus; in contrast to EC 2.4.2.8, this enzyme also uses xanthine as substrate; mw 24 kD Registry number: EC 2.4.2.- Synonym: hgxprtase (26 Jun 1999) |
| hypoxanthines | Purine bases related to hypoxanthine, an intermediate product of uric acid synthesis and a breakdown product of adenine catabolism. (12 Dec 1998) |
| hypoxanthinosine | The fifth base of nucleic acids. Important because it fails to form specific pair bonds with the other bases. In transfer RNAs, this property is used in the anticodon to allow matching of a single tRNA to several codons. PCR perfomed with primers containing inosine tolerates a limited degree of mismatch between primer and template, useful in homology probing. (18 Nov 1997) |

| hypoxia |
Oxygen depletion is a phenomenon that occurs in aquatic environments as dissolved oxygen (DO; molecular oxygen dissolved in the water) becomes reduced in concentration to a point detrimental to aquatic organisms living in the system. Dissolved oxygen is typically expressed as a percentage of the oxygen that would dissolve in the water at the prevailing temperature and salinity (both of which affect the solubility of oxygen in water; see oxygen saturation and underwater). ...
