    Notes: Abstract In wounded cotyledons ofPhaseolus vulgaris L. the accumulation of the 5-hydroxy isoflavonoids kievitone and 2′-hydroxygenistein precedes the major increases in the levels of the 5-deoxy compounds phaseollin and coumestrol. Increased phytoalexin levels are preceded by transient increases in the extractable activities of L-phenylalanine ammonia-lyase (EC 4.3.1.5.), chalcone synthase and chalcone isomerase (EC 5.5.1.6.). Accumulation of phytoalexins, above wounded control levels, is observed following treatment of excised cotyledons or hypocotyls with crude or fractionated elicitor preparations heat-released from the cell walls ofColletotrichum lindemuthianum. Chalcone synthase levels are also induced in cotyledons, although crude elicitor and all fractions suppress L-phenylalanine ammonia-lyase activity in both tissues. Kievitone is the major phytoalexin induced in cotyledons, whereas in hypocotyls phaseollin predominates. Patterns of phytoalexin accumulation have been studied in response to varying concentrations of the crude and fractionated elicitor; 5-hydroxy isoflavonoid accumulation is highly dependent upon elicitor concentration, the dose-response curves for kievitone accumulation showing maxima at around 1 μg glucose equivalents per cotyledon, minima at 2–3 μg equivalents and increasing induction at higher concentrations. Similar patterns are observed for L-phenylalanine ammonia-lyase and chalcone synthase levels, although the overall extent of these changes is masked by the high wound response. Accumulation of 5-deoxy isoflavonoids above control levels requires high elicitor concentrations; no experimental conditions were found under which phaseollin accumulated to higher levels than kievitone in cotyledons during the first 48 h after elicitation.

    Notes: Abstract  Blending of native wheat flour (NWF) and steamed wheat flour (SWF) in the ratio of 1 : 1was found to give good binding between the filling and coating, and improve the overall quality of the coated products. The apparent viscosity increased with increase in batter concentration (30, 33 and 36%) of all the three blends, namely NWF+SWF (5 min steaming period), NWF+SWF (15 min steaming period) and NWF+SWF(30 min steaming period). The yield stress and consistency index also increased with increase in batter concentration for all three blends. The gel mobility increased with increased steaming period of the blends. The rapid visco analyser used for measuring the pasting characteristics of the blends showed an increase in peak viscosity from 218 to 243 rapid visco units (RVU), in hot pasteviscosity from 81 to 100 RVU and in cold paste viscosity from 175 to 185 RVU. The area under the curve also increased from 1963 to 2134 RVU/min for the blends when compared with native wheat flour.

    Preparation and evaluation of 99mTc(V)-DMSA complex: Studies in medullary carcinoma of thyroid (1987)

    Notes: Abstract Consequent to the promising results reported with 99mTc(V)-DMSA for imaging certain types of soft tissue tumors, we have developed methods to prepare this radiopharmaceutical in three ways:-(i) from freshly prepared reagents, (ii) through the use of a two component kit and (iii) use of the standard renal DMSA kit by a modified recipe. The 99mTc(V)-DMSA complex has been subjected to paper electrophoretic and chromatographic procedures and also biodistribution studies. The distinctly different behaviour of this new product compared to that of the well known renal DMSA complex has been clearly established. Scintiimaging in a preliminary clinical trial in patients with medullary carcinoma of the thyroid has been encouraging.
