铁粒幼细胞是一种具有异常铁的累积的幼稚红细胞,骨髓中的铁粒幼细胞有中间或铁蛋白和环状两种不同类型。正常有核红细胞可含有5个以下铁颗粒,这些颗粒是铁与铁蛋白相结合而散乱地分布在细胞浆内,当胞浆内铁颗粒超过6个,这种有核红细胞称为中间型或铁蛋白型铁粒幼细胞。在正常骨髓中此型铁粒幼细胞可高达14%。环状铁粒幼细胞是一种含有粗大铁颗粒的幼稚红细胞,这些铁颗粒通常至少围绕核周围的1/3,并排列成环形。环状铁粒幼细胞发生机理可能包括调节血红素合成酶的特殊障碍,这些铁颗粒位于线粒体内的含铁微胶粒中。在正常骨髓内无环状铁粒幼细胞。分别计数环状和
Myeloid leukocytes are an accumulation of naïve erythrocytes with abnormal iron, and there are two different types of myeloblasts in the bone marrow, intermediate or ferritin and ring. Normal nucleated red blood cells can contain less than 5 iron particles, these particles are the combination of iron and ferritin and scattered in the cytoplasm, when the intracytoplasmic iron particles more than 6, this nucleated red blood cells called intermediate or Ferritin-type iron granule cells. In normal bone marrow this type of iron granulocyte up to 14%. Cyclic iron granules are a type of naive red blood cells containing coarse iron particles, which usually surround at least 1/3 of the circumference of the nucleus and are arranged in a ring shape. Cyclic iron granulocyte growth mechanism may include the special barrier of regulating heme synthase, which is located in the iron-containing micelles within the mitochondria. In the normal bone marrow within the ring-like iron -based young cells. Respectively count the ring and
