RESUMO
Hemangiopericytoma (HPC) is a rare vascular tumour and difficult to diagnose clinically. Incidence is reported in fourth to fifth decade of life.With female predominance, 3%-5% cases affect the oral cavity, sinus lining and meninges. The patient presented with 8×6 cm swelling on her face, evaluation reported it to be HPC. Bilateral maxillary artery embolisation, wide local excision of the lesion, preserving the left eye and its function, was done. No recurrence is reported at 1-year follow-up. Response of such lesions to radiotherapy is questionable; with no lymphadenopathy and adequate encapsulation, embolisation of feeder vessel followed by a wide local excision of the lesion seems to be a fairly good option of treatment.

A clinico radiological comparative study of complications in the anaesthetic foot in 60 patients (48 leprosy and 12 spinal injuries) were done. It has been observed that these groups behave differently.

The elution profile of urine from rats given 63Ni i.p. using a Sephadex G-25 column was studied to investigate the chemical form and pattern of nickel (Ni) excretion. Ni was excreted probably as a mixture of complexes with chemical constituents of urine (molecular weight 200-250) within 24 h after 63Ni injection. 63Ni increased significantly the excretion of proteins, absorbing at 280 nm, which were not associated with Ni. The administration of N-acetyl-DL-penicillamine 24 h after 63Ni injection increased significantly the urinary excretion of the metal and restored proteinuria during the next 24 h. It could not be ascertained whether N-acetyl-DL-penicillamine enhanced urinary excretion of 63Ni by forming an excretable complex or by modifying the excretory pathway.

The formation constants, beta(MAL), for the reaction VO(2+) + A(-) + L(2-) <==> VOAL(-) [where HA = picolinic acid and H(2)L = salicylic or 5-sulphosalicylic acid] have been determined at 30 +/- 1 degrees (mu = 0.1, KNO(3)). Potentiometric evidence is presented for the simultaneous addition of both ligands to the metal ion to form the 1:1:1 ternary complex.
