Effects of biofertilizer containing N-fixer, P and K solubilizers and AM fungi on maize growth: A greenhouse trial.
An in vitro study was undertaken to evaluate the compatibility of indigenous plant growth promoting rhizobacteria (PGPR) with commonly used inorganic and organic sources of fertilizers in tea plantations. The nitrogenous, phosphatic and potash fertilizers used for this study were urea, rock phosphate and muriate of potash, respectively. The organic sources of fertilizers neem cake, composted coir pith and vermicompost were also used. PGPRs such as nitrogen fixer; Azospirillum lipoferum, Phosphate Solubilizing Bacteria (PSB); Pseudomonas putida, Potassium Solubilizing Bacteria (KSB); Burkholderia cepacia and Pseudomonas putida were used for compatibility study. Results were indicated that PGPRs preferred the coir pith and they proved their higher colony establishment in the formulation except Azospirillum spp. that preferred vermicompost for their establishment. The optimum dose of neem cake powder

Measurement of Fibrinopeptide A in Human Blood
A (FPA) and B from the NH2-terminal end of the fibrinogen molecule, measurement of librinopeptide levels in plasma may provide a direct index of thrombin action. Recently a radioimmunoassay for FPA has been developed, and in the present paper, we describe the application of this assay to the measurement of FPA levels in clinical blood samples. Since fibrinogen cross-reacts with antibodies to FPA, dialysis was used to extract the peptide from plasma. In vitro generation of FPA was prevented by removing the fibrinogen from the plasma by precipitation with ethanol before dialysis. The processing technique permitted recovery of 75 % of FPA added to blood in vitro. Evidence that the immunoreactivity measured in plasma is due to FPA was provided by the results of experiments in which two antisera t
