This study compares the inhibitory effect of ceftizoxime with that of penicillin G, chloramphenicol, cephalothin, cephalexin and cefzoline on Klebsiella pneumoniae, Proteus mirabilis, pseudomonas ruginosa, staphylococcus aureus, staphylococcus epidermidis, staphylococcus saprophyticus and Escherichia coli. The in vitro inhibitory effect of ceftizoxime on P. mirabilis, P. Aeruginosa, S.prophytic...

The purpose of the present study has been to determine the change in the resistance of corpuscles to saponin with changes in pII., the acids employed being the common inorganic acids. Ponder (1) has shown that the rate of saponin hemolysis is increased in the presence of certain acids and has applied the equation Cl = R (C, + g) to systems in which an acid is the accelerating agent. Details of ...

On account of some undesirable features of the simplified Bunzel oxidase apparatus) the author has designed a simple apparatus (Fig. 1) incorporating the advantages of both the simplified Bunzel apparatus and the original design. 2 The simplified Bunzel oxidase apparatus makes no provision for the absorption of CO~ other than by the reagents used. In some reactions the CO2 production cannot be ...

When asked to combine two pieces of evidence, one diagnostic and one non-diagnostic, people show a dilution effect: the addition of non-diagnostic evidence dilutes the overall strength of the evidence. This non-normative effect has been found in a variety of tasks and has been taken as evidence that people inappropriately combine information. We investigated the dilution effect using simple per...

A highly sensitive radioimmunoassay for alpha-human atrial natriuretic peptide (alpha-hANP) was established and applied to measure the human plasma alpha-hANP levels. In our assay system, anti-alpha-hANP antiserum was raised in albino rabbits by intradermally injecting synthetic alpha-hANP which was conjugated with bovine serum albumin. The final antiserum dilution was 1:50,000. Sensitivity was...

objective the purpose of this study was to assess the frequency of complications of endotracheal intubation (eti) in neonates. methods the newborns that were admitted and needed urgent or semi-urgent intubation were enrolled in this study over a 1 year period. route for intubation in all cases were orotracheal. cases were not routinely sedated or paralyzed. the patients were clinically and radi...

background and purpose: inserting a nasogastric tube, though a common clinical procedure with widespread use for critically ill patients, can produce unexpected complications so that tube misplacement into the lungs is a potential complication with serious consequences. the reliability of common bedside methods to differentiate between pulmonary and gastric placement has not been acceptable. th...

Aegle marmelos is a medicinal herb that has variety of biological constituents. “Catechins” are class phenolic compounds have therapeutic value. The present study employs batch extraction with methanol as solvent to extract the catechins from pulp fruit. Box–Behnken design response surface methodology (RSM-BBD) used optimize operational parameters impacting catechin extraction, such concentrati...

Exoelectrogenic bacteria have potential for many different biotechnology applications due to their ability to transfer electrons outside the cell to insoluble electron acceptors, such as metal oxides or the anodes of microbial fuel cells (MFCs). Very few exoelectrogens have been directly isolated from MFCs, and all of these organisms have been obtained by techniques that potentially restrict th...
