Vanadium (V) has recently been found to possess potent anti-neoplastic activity in rat hepatocarcinogenesis. Recent studies have suggested that the active metabolite of vitamin D(3), 1alpha, 25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)], can inhibit growth and/or induce differentiation of a variety of cell types. In the present study, attempts have been made(More)
The effect of streptozotocin-induced diabetes in male Sprague-Dawley rats was investigated to ascertain whether it has had any modulating role in hepatocarcinogenesis. Hepatocarcinogenesis was initiated with a single sub-necrogenic dose of diethylnitrosamine (DEN) (125 mg/kg body weight, i.p.) whilst acute diabetes was produced with a single i.p. injection(More)
The combined effects of vanadium (V) and 1alpha,25-dihydroxyvitamin D3 [1,25(OH)2D3] in inhibiting diethylnitrosamine (DEN)-induced and phenobarbital (PB) promoted hepatocarcinogenesis were examined in male Sprague-Dawley rats. All the rats were subjected to 70% partial hepatectomy (PH) at week 4 and 24h later were administered either solvent trioctanoin(More)
Vitamin D3, having gained scientific interest for so long because of its role in mineral homeostasis, has now received great importance as a possible antitumor agent. This study was undertaken in an attempt to visualize the possible anticlastogenic potential of the vitamin in an ascitic mouse lymphoma model namely, Dalton's lymphoma. Frequencies of(More)
The active metabolite of vitamin D, 1 alpha,25-dihydroxyvitamin D(3)[1,25(OH)(2)D(3)] has been receiving increasing attention and has come to the forefront of cancer chemoprevention research as being a regulator of cellular growth, differentiation and death. In the present study, attempts have been made to investigate the in vivo chemopreventive effect of(More)
A combination of a differentiation-inducing agent like 1alpha, 25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] with a compound that blocks entry of calcium into cells like vanadium (V) may offer a new approach to differentiation therapy and address the problem of hypercalcemia. Initiation of hepatocarcinogenesis was performed by a single intraperitoneal(More)
A 2-month-old infant presented to our emergency department with fever, altered consciousness, and focal seizures of acute onset. He had vesicular skin lesions over the right preauricular region. CT brain showed a large hypodense lesion involving the left temporo-parietal region, left basal ganglia and left thalamus. MRI brain revealed bilateral multifocal(More)
This report describes a 10-month-old infant who presented with generalised tonic clonic seizures following 2 days of vomiting, diarrhoea and a low-grade fever. The patient was moderately dehydrated and the blood investigations were remarkable for hyponatraemia (126 mEq/l), leukocytosis (19.4 × 10(3)/l (46% lymphocytes)), thrombocytosis (637 × 10(3)/l),(More)
Erythrocyte indices used to differentiate between iron deficiency anaemia (IDA) and thalassaemias have been studied mainly in countries with a high prevalence of IDA or beta-thalassaemias. This study was carried out in the United Arab Emirates where alpha-thalassaemias are prevalent. We studied the predictive value and Youden index of several indices in 85(More)
Churg-Strauss Syndrome (CSS) is rare in children. It consists of a small- and medium-sized vessel vasculitis, with skin and peripheral nerve involvement. It is characterized by eosinophilia, extravascular necrotizing granuloma, and eosinophilic infiltration of multiple organs particularly the lungs, but may also involve the gastrointestinal tract, the(More)
