On-farm and experimental measures of the proportion (%Ndfa) and amounts of N2 fixed were undertaken for 158 pastures either based on annual legume species (annual medics, clovers or vetch), or lucerne (alfalfa), and 170 winter pulse crops (chickpea, faba bean, field pea, lentil, lupin) over a 1200 km north-south transect of eastern Australia. The average(More)
This article reports a death occurring in an apparently healthy, 27-year-old male as a consequence of an adverse reaction to a common urinary tract antibiotic (nalidixic acid). The deceased had cardiac enlargement at autopsy. The clinical presentation before his sudden death coincides with the occurrence of seizures and psychotic reaction as an adverse(More)
Genetic instability within strains of rhizobia maintained on laboratory media is well recognized, although rarely has the mutation been characterized. Variability within a strain introduced into the field is very difficult to recognise due to poor understanding of naturally-occurring populations of rhizobia. We have examined populations of Rhizobium(More)
A 35-year-old female with a history of cardiac problems was found dead. She had been prescribed 40 mg of propranolol (Inderal) to be taken twice daily. Autopsy revealed the presence of a green liquid in the stomach, but there was no anatomic cause of death. Toxicologic analyses of appropriate body fluids confirmed the suspicion that the deceased had(More)
The effect of rice culture on changes in the number of a strain of soybean root-nodule bacteria, (Bradyrhizobium japonicum CB1809), already established in the soil by growing inoculated soybean crops, was investigated in transitional red-brown earth soils at two sites in south-western New South Wales. At the first site, 5.5 years elapsed between the harvest(More)
Phendimetrazine is an anorectic agent which recently has been detected in three medical examiner's cases. In one instance death was attributed to this drug. Methods of detecting and identifying this drug in urine and blood are discussed. In the one instance where death was attributed to this substance, the blood concentration was 300 ng/ml.
Toxicological and pathological findings are described in fatalities involving pentazocine (Talwin) and tripelennamine (Pyribenzamine). Procedures using thin-layer chromatography, gas chromatography, ultraviolet spectrophotometry, and spectrophotofluorometry are described, as well as the quantitative analysis of biological specimens of drug abuse and(More)
