Twelve to 13 ml. of blood from the cords of 49 normal human newborns were collected immediately after delivery and put in tubes containing 500 units of heparin. The blood was treated according to the methods described previously, and smears stained with MayGr#{252}nwald Giemsa method were examined. In addition, in 10 cases the cells were investigated for alkaline phosphatase activity.6 In 12 ca...

Blood morphology in dogs infected with intracellular parasites of the genera Babesia and Ehrlichia was examined. The parasites were detected in peripheral blood smears stained by the May-Grünwald-Giemsa method. During the parasitic invasion, a decrease in thrombocyte counts was observed. This was connected with forming platelet aggregates. It was noted that the number of giant platelets simulta...

After the use of different Giemsa staining techniques, variations in chromosome banding patterns have often been observed in animal chromosomes. Such staining differences are usually interpreted to indicate that there is more than one type of heterochromatin in many animal chromosomes. Using two differential Giemsa staining techniques we have found different staining patterns in the chromosomes...

Background: The use of conventional stains including Giemsa, Wright and Leishman have become an essential tool for differential diagnosis of cells in peripheral blood. Aims: The aim of the study was to develop a new combination of Leishman-Giemsa (L&G;) stain for avian blood smears and to compare its efficacy with conventional staining methods. Methods:<...

background: haemobartonella (also known as mycoplasma) is a blood organism of cats and can cause many anemia and many clinical signs in the infected cats. objectives: the purpose of the present study is to calculate the incidence rate of haemobartonellosis in pet cats of tehran and study its relationship with certain factors. moreover, some blood parameters in the infected cats were compared wi...

BACKGROUND The aim of this study was to establish the frequency of fetal cells in the maternal blood of multifetal pregnancies and compare this figure with singleton pregnancies. METHODS We obtained maternal blood from 31 pregnancies with 2-6 fetuses at 11-16 weeks gestation and from 50 normal singleton controls (11-14 weeks gestation). Fetal erythroblasts were isolated from maternal blood us...
