SOME small dye molecules can bond with proteins, the spectrum of which has a characteristic of energy transferring, i.e. enhancement or quenching of fluorescence. Much information can be obtained from this phenomenon, and can be used to determine the distance between the macrobiomolecules and some groups, such as the distance between aromatic amino acid of proteins and ligands. So they are often called 'a spectroscopic ruler'. We deduced the theoreti-

Objective:To assess if microhaematuria and proleinuria as measured by reagent strips could estimate intensity of Schistosoma haematobium(***) infection in endemic areas and evaluate their screening performance among children in Benue State,***:A lolal of 1124 urine samples were collected,screened for microhaematuria and proteinuria using reagent strips(Combi 9) and results were compared to filtration technique,the gold standard ***:A significant correlation was ohserved between microhaematuria(rho= 0.66.

Irritable bowel syndrome(IBS) is a common, sometimes debilitating, gastrointestinal disorder worldwide. While altered gut motility and sensation, as well as aberrant brain perception of visceral events, are thought to contribute to the genesis of symptoms in IBS, a search for an underlying aetiology has, to date, proven unsuccessful. Recently, attention has been focused on the microbiota as a possible factor in the pathogenesis of IBS. Prompted by a number of clinical observations, such as the recognition of the de novo development of IBS following enteric infections, as well as descriptions of changes in colonic bacterial populations in IBS and supported by clinical responses to interventions, such as antibiotics and probiotics, that modify the microbiota, various approaches have been taken to investigating the microbiota-host response in IBS, as well as in animal models thereof. From such studies a considerable body of evidence has accumulated to indicate the activation or upregulation of both factors involved in bacterial engagement with the host as well host defence mechanisms against bacteria. Alterations in gut barrier function, occurring in response, or in parallel, to changes in the microbiota, have also been widely described and can be seen to play a pivotal role in generating and sustaining host immune responses both within and beyond the gut. In this manner a plausible hypothesis, based on an altered microbiota and/or an aberrant host response, for the pathogenesis, of at least some instances of IBS, can be generated.
