Hemorrhagic manifestation in different etiologies of pancytopenia: A prospective, cross-sectional study.

Background: Pancytopenia is a triage of anemia, leukopenia, and thrombocytopenia. The etiology causing pancytopenia varies depending upon factors such as age, sex, occupation, and geographical distribution. Unfortunately, the major treatises of hematology have not given emphasis on the hemorrhagic manifestation of different etiologies causing pancytopenia.

N-(1,3-Thia-zol-2-yl)-N'-[(thio-phen-2-yl)carbon-yl]thio-urea hemihydrate.

The title compound, C9H7N3OS3·0.5H2O, crystallizes with two independent but similar mol-ecules in the asymmetric unit, both of which are linked by a water mol-ecule through O-H⋯N hydrogen bonds. In addition the water O atom is further linked by N-H⋯O hydrogen bonds to two additional main mol-ecules, forming a tetra-meric unit.

Methyl 2-(thio-phene-2-carboxamido)-benzoate.

The title compound, C(13)H(11)NO(3)S, was synthesized from methyl anthranilate, triethyl-amine and 2-thio-phenoyl chloride in benzene. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The dihedral angle between the rings is 2.
