A Comparison Of Skeletal Age Of Thalassaemic Patients Of 9-15 Years With Chronological Age By Radiography.

Background: Thalassemia is inherited disorder characterized by haemolytic anaemia, due to complete absence or reduced β-globin chain synthesis, stimulating pathological bone marrow overstimulation and altered erythropoiesis. The change in bone mass ultimately results into miss interpretation of bone age once assed from x-ray radiograph. The aims compare skeletal age of thalassaemic children of 9-15 years with chronological age by x-ray wrist bones.

[(Methyl-carbamothio-yl)disulfan-yl]methyl N-methyl-carbamodithio-ate.

The title compound, C(5)H(10)N(2)S(5), was unintentionally obtained as the product of an attempted synthesis of a methyl-carbamodithioic acid using methyl-amine and carbon disulfide. In the mol-ecule, two dithio-carbamate groups are bridged by a -CH(2)S- unit. The C-S-S-C torsion angle is -90.

3-(4-Chloro-phen-yl)-2-methyl-acrylic acid.

In the crystal structure of the title compound, C(10)H(9)ClO(2), dimers form as a result of inter-molecular O-H⋯O bonding. These dimers are linked to each other via C-H⋯O bonds, where the CH group belongs to the benzene ring and the O atom is from the carbonyl group of an adjacent mol-ecule. There exist two inter-molecular C-H⋯O hydrogen bonds, which individually form five-membered rings.

1-Methyl-1H-benzimidazole-2(3H)-thione.

The title compound, C(8)H(8)N(2)S, was prepared by the condensation of N-methyl-1,2-phenyl-enediamine and carbon disulfide. The crystal structure is stabilized by a C-H⋯π inter-action between a benzene H atom and the benzene ring of a neighbouring mol-ecule, and by inter-molecular N-H⋯S inter-actions.
