Chemical Composition of Herbal Macerates and Corresponding Commercial Essential Oils and Their Effect on Bacteria Escherichia coli.

This study addresses the chemical composition of some commercial essential oils (clove, juniper, oregano, and marjoram oils), as well as appropriate herbal extracts obtained in the process of cold maceration and their biological activity against selected strains: ATTC 25922, ATTC 10536, and 127 isolated from poultry waste. On the basis of the gas chromatography-mass spectrometry (GCMS) analysis, it was found that the commercial essential oils revealed considerable differences in terms of the composition and diversity of terpenes, terpenoids and sesquiterpenes as compared with the extracts obtained from plant material. The commercial clove, oregano, and marjoram oils showed antibacterial properties against all the tested strains of .

The use of invertebrates to detect small-scale habitat heterogeneity and its application to restoration practices.

Recent conceptual and technological solutions to biodiversity assessment allow large numbers of invertebrate specimens to be processed rapidly and provide researchers and practitioners with a unique tool for characterizing habitats. One application of these advances is the ability to detect and monitor small-scale habitat heterogeneity and so provide a measure of ecosystem restoration. This case study presents a test of the efficacy of using invertebrates to assess and monitor ecological restoration following bush regeneration.

Hepatitis in a family infected by Chlamydia psittaci.

Hepatic involvement is considered a rare complication of psittacosis. Occurrence of icteric hepatitis as the cardinal manifestation of the disease has been rarely reported. We describe two members of a family infected by psittacosis, in whom icteric hepatitis was the prominent expression of the disease.

Haemoptysis as the sole presenting symptom of dissection of the aorta.

A 75 year old man who had had haemoptysis for 24 hours was found to have his left lower lobe compressed by a dissection of the aorta, which was otherwise symptomless.
