Preliminary Results

A technique for determining the large angle light-scattering patterns of biologic cells has been developed and applied to the measurement of isolated calf oligodendroglia. Preliminary results indicate that light-scattering information can be used to discriminate between oligodendroglia, subcellular debris and red blood cells and also suggest that oligodendroglia can be distinguished from neurons.

Light Scattering Technique

A low-angle light scattering technique, which has been applied previously to studies of blood platelets and Ehrlich ascite tumor cells, revealed differences in the dynamics of necrotic and apoptotic red blood cell death. Under hypotonic loading or in ammonia medium, red blood cells (RBC) swelled to a critical size (diameter approximately 13μm) prior to hemolysis (necrosis). Under acidic loading, hemolysis occurred with less pronounced swelling of cells (diameter approximately 10μm). Apoptosis induced by a calcium ionophore resulted in initial formation of echinocytes, followed by development of rounded red blood cells with uneven membrane, capable of agglomeration. In such a way, RBC aggregation can precede the final stages of the RBC apoptosis when small cellular fragments are generated. On the basis of erythrograms of the cells hemolysing in ammonia medium, the echinocytic (preapoptotic) and stomatocytic (prenecrotic) RBC were discerned due to the very high resistance of apoptotic RBC to osmotic (ammonia) loading.

Hematological Values

Some hematological values, blood total protein, protein fractions, and minerals such as calcium and phosphorus of takhi, which are now being reintroduced in Khustain natural park, were measured. There were 8.3 million red blood cells and 8000 white blood cells in 1 mm3 whole blood of takhi reintroduced in Khustain natural park, and hemoglobin was 179.6±3.2 g/l. As well, total proteins, calcium and phosphorus of takhi were 67± 0.6 g/l, 2.1±0.31 mmol/l, and 1.1±0.2 mmol/l respectively and they were similar to those in Mongolian horses. It has been necessary to investigate further adaptability of takhi in asscoation with both internal and external environments of its body.DOI: http://dx.doi.org/10.5564/mjas.v11i2.206 Mongolian Journal of Agricultural Sciences Vol.11(2) 2013 pp.3-6
