Retina and choroid were rapidly and gently extracted from chickens, guinea-pigs, rats, rabbits and cows. They were frozen, weighted and pooled in 3% trichloroacetic acid in a refrigerator. Using a radioenzymic assay, histamine was found to be present in the retina of guinea-pig (4.26 +/- 0.677 nmol g-1), rabbit (1.08 +/- 0.422 nmol g-1) and cow (0.189 +/- 0.036 nmol g-1), but not detected in chicken and rat. In the choroid, histamine was found in all species except rat (chicken: 4.92 +/- 0.542 nmol g-1; guinea-pig: 121.5 +/- 4.46 nmol g-1; rabbit: 18.7 +/- 3.93 nmol g-1; cow; 0.36 +/- 0.095 nmol g-1). The study verifies the presence of histamine in the retina of some species, and thereby supports previous fluorometry assays.
从鸡、豚鼠、大鼠、兔和牛身上快速轻柔地取出视网膜和脉络膜。将它们冷冻、称重后，置于冰箱中的3%三氯乙酸中混合。采用放射酶分析法，发现组胺存在于豚鼠（4.26±0.677纳摩尔/克）、兔（1.08±0.422纳摩尔/克）和牛（0.189±0.036纳摩尔/克）的视网膜中，但在鸡和大鼠中未检测到。在脉络膜中，除大鼠外，所有物种均发现有组胺（鸡：4.92±0.542纳摩尔/克；豚鼠：121.5±4.46纳摩尔/克；兔：18.7±3.93纳摩尔/克；牛：0.36±0.095纳摩尔/克）。该研究证实了某些物种视网膜中组胺的存在，从而支持了先前的荧光测定法。
