Decidual CD56+ Natural Killer Cells in Spontaneous Early Pregnancy Loss- An Immunohistochemical Study.

Introduction: Natural killer cells are believed to promote placental and trophoblastic growth and provide immune- modulation at maternal-fetal interface in pregnancy and their role in reproductive failure has been a matter of discussion.

Aim: To study CD56+ Natural killer cells in spontaneous pregnancy loss.

Materials And Methods: In this prospective observational study, formalin-fixed paraffin embedded sections from products of conception from twenty women each with spontaneous early pregnancy loss (test group) and elective pregnancy termination (control group).

Automated measurement of immature granulocytes: performance characteristics and utility in routine clinical practice.

The granulocytic "shift to left" reflects marrow response to bacterial infection, and this may be quantified as band count or immature granulocyte count (IGC). The former value, used widely in neonatal sepsis, has been notoriously difficult to measure accurately and precisely. A reproducible, precise, and accurate counting of immature granulocyte counts may be possible with automation.
