贵刊1991年第三期发表了《鱼鳔胀缩悟浮沉》一文,有的读者提出一些疑义.现就以下问题谈谈个人的观点,与牛乐耕同志商榷.一、气腺是“将气体源源不断地分泌并排入鳔内”的吗?鱼鳔上有一特殊血管区,称作迷网,其进出微血管平行而不分枝,约有88000-250000个发夹状“u”形攀.迷网末端嵌有腺上皮,其生理功能有强烈的糖酵解作用,产生的大量乳酸能降低迷网微血管中血液的pH值及血红蛋白对氧的亲和力,促进迷网“静脉血”释放氧气并向微动脉扩散.因此,当血液流经迷网微血管时,逆流倍增系统能形成高达2000个大气压的氧分压,在氧分压超过鳔内
In the third issue of your article published in the third issue of 1991, some readers raised some doubts. Let’s talk about the individual’s point of view on the following issues and discuss it with Comrade Niu Lengeng. I. The gonads are Does the gas continue to be secreted and drained into the orbit? There is a special vascular area on the surimi, called the plexus, which flows in and out of the microvessels without branching. There are about 88,000 to 250,000 hairpins.“u” Shape climbing. The end of the labyrinth embedded with glandular epithelium, its physiological function has a strong glycolytic effect, the large amount of lactic acid produced can reduce the blood pH value of hemoglobin microvessels and the affinity of hemoglobin to oxygen, to promote the network of venous blood "The release of oxygen diffuses into the arteries. Therefore, when the blood flows through the labyrinth microvessels, the countercurrent multiplication system can create an oxygen partial pressure of up to 2,000 atmospheres.
