    ABSTRACT Fluoride has been considered to cause hepatic and renal tissue damages in animals and humans. The present study investigated the effect of varying concentrations of fluoride on hepatic and renal enzyme profile in domestic chicken (n=80). Chicken were distributed into 4 groups. Group A was kept unexposed while group B, C and D were exposed to 10, 20 and 30 µg/g body weight of NaF respectively on weekly basis for four weeks. Alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine amino-transferase (ALT) and bilirubin were determined as indicators of liver function test (LFT), while uric acid was as a parameter for renal function test (RFT). All LFT and RFT parameters showed high values (P< 0.05) after one, two three and four weeks in all groups. 579.4 ± 1.55, 355.0 ± 2.13, 246.2 ± 2.45 and 0.83 ± 1.46 were the ALP, AST, ALAT and bilirubin values for LFT and uric acid was 6.74 ± 2.92 in D group at the end of four weeks. All these results indicate the probability of severe effect on the physiology of the liver and kidneys in the exposed birds

    Short report: craniosynostosis, a late complication of nutritional rickets

    No full text
    OBJECTIVES: Nutritional rickets may be a preventable cause of craniosynostosis. This potential association is under-recognised. A late diagnosis of craniosynostosis may result in reduced brain growth, raised intracranial pressure and long-term psychosocial problems. CASE PRESENTATION: We present four cases of craniosynostosis associated with nutritional rickets. Those who had delayed presentation underwent emergency craniotomy. CONCLUSIONS: Treatment of nutritional rickets and early identification of craniosynostosis can reduce morbidity in these children

    Modeling of Natural Transition in Properly Three-Dimensional Flows

    The paper describes a method for viscous flow prediction which includes the prediction of transition onset location as an integral part of the calculation. The method is similar to others in that it is based on stability analysis of the boundary layers but acknowledges that solutions of the Reynolds-averaged Navier-Stokes (RANS) equations yield boundary layers of inadequate accuracy when conventional mesh sizes are used. The boundary layers are therefore recomputed to high accuracy by solving the laminar boundary layer equations. Transition onset locations determined by the stability analysis are passed back to the RANS solver for further iterations. The method described in this paper differs from others in that the laminar boundary layer calculation is fully three-dimensional and the stability analysis is through the fully three-dimensional parabolised stability equations for compressible flow. Results are presented to illustrate the capability of the laminar boundary layer method and the effectiveness of the method for solving the parabolised stability equations. In addition, preliminary validation results are presented from calculations of the viscous flow over the AFRL 1303 UCAV concept to demonstrate that the fully three-dimensional laminar boundary layer and stability analysis components can be combined successfully with a RANS method for calculating flows with natural transition
