Splenic Erythroclasia: An Electron Microscopic Study of Hemoglobin H Disease

Splenic erythroclasia: an electron microscopic study of hemoglobin H disease.

Pregnancies Complicated by Hemoglobin H disease

Dear Editor-in-Chief The recent report on “The Adverse Effects of Pregnancies Complicated by Hemoglobin H (HBH) Disease” is very interesting (1). Rabiee et al. reported a pregnant case complicated with HBH disease. Indeed, this problem might not common in the Middle East but it is very common in Southeast Asia. The authors hereby would like to share the experience on this top...

Heterozygote Hemoglobin J Iran in Combination with Hemoglobin H Disease

This is a report concerning a concurrent case of hemoglobin J Iran (Hb J Iran) and Hemoglobin H (Hb H) disease in an Iranian woman. The patient was coincidentally found during the course of routine pre-marital genetic counselling for her son. The diagnosis of heterozygote Hb J Iran for her son, ultimately led to the diagnosis of concurrent Hb J Iran and Hb H disease. The hematological examinati...

An Electron Microscopic Study of Erythrophagocytosis

The present study describes a submicroscopic surface fragmentation of erythrocytes which occurs in the ascitic fluid of rats bearing the Novikoff ascites hepatoma. The resulting fragments attach to the surface of macrophages and are phagocytized by pseudopod formation. Plasma membrane in the region of these phagocytosis vacuoles appears to condense into electron-opaque material, suggesting an a...

An Electron Microscopic Study on the Toad

In spite of numerous investigations, the nature and function of the subcommissural organ (SCO) located beneath the posterior commissure was not clear owing to poor staining methods, and for a long time this organ was regarded as one of the most mysterious organs. However, since recently a variety of special staining methods including GOMORI's chrome alum hematoxylin and other histochemical tech...
