    USE OF WATER FROM THE ANCIENT MAKKAH GALLERIES FOR IRRIGATION (1994)

    Notes: : Due to the spread of Islam in the seventh century the number of pilgrims to the City of Makkah increased sharply, resulting in an acute water shortage. To solve this problem, galleries were built to collect water from the upstream of Wadi Naaman and transfer it to Makkah.Expansion of Makkah and the absence of any mapping of the galleries have resulted in the destruction of a part of the galleries. This caused a discontinuity of flow in the galleries and, consequently, the ground water table is rising at a rate of 0.48 m/yr, causing environmental problems. Research was conducted to rehabilitate the destructed part of the galleries, and to find an appropriate use for the ground water. The study found that the quality of the ground water is suitable for landscaping purposes, that is, for the irrigation of trees and ornamental plants.

    Volatile flavour compounds of yoghurt (1992)
    Oxford, UK : Blackwell Publishing Ltd
    International journal of food science & technology 27 (1992), S. 0

    Notes: The volatile flavour compounds of three samples of Egyptian yoghurt were analysed over a two-week period at 8°C using a simple headspace gas chromatography technique in order to study the changes and relate them to flavour acceptability.Volatile compounds present were acetaldehyde, diacetyl, acetoin, acetone, butanone, and acetic acid. Acetone and butanone disappeared within the first week of storage, whereas acetaldehyde, diacetyl and acetoin declined steadily but were still present after two weeks. Acetic acid increased to about twice its original level after 10d of storage.The decreases in acetaldehyde, diacetyl, acetoin, and the increase of acetic acid were closely related to the rapid decrease in product acceptability after 8–10d storage.

    Quantification of microvascular changes in the skin in patients with psoriasis (1992)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 126 (1992), S. 0 
    Details

    Topics: Medicine
    Notes: Summary It has been suggested that there is a widespread abnormality of the capillaries in the skin of patients with psoriasis. This study was carried out to obtain more evidence on this point. Lesions of 20 patients with typical psoriasis, and uninvolved skin 3 cm from these lesions, were biopsied and compared with biopsies from 10 normal healthy control subjects. The dermal microvasculature was quantified in all these biopsies with regard to endothelial and luminal volume relative to the volume of dermal components of skin using stereological point counting methods utilizing the Delesse principle.The values for endothelial volume in specimens taken from the centre of the lesions did not differ significantly from those taken from the margins (33.6 × 10−3 and 35.8 × 10−3, respectively). The same was true for the luminal volume from the two sites (9.1 × 10−3 and 10.0 × 10−3, respectively). There was a highly significant difference, however, between the value for endothelial volume in biopsies from psoriatic patients compared to controls (P 〈 0.001) and specimens from uninvolved psoriatic skin also showed a highly significant difference (P 〈 0.001) from involved areas. There was no significant difference between uninvolved areas in psoriasis patients and control specimens. Significant differences were also found between values for control subjects and those for both involved and uninvolved psoriatic skin for luminal volume (P 〈 0.001). The number of capillary profiles counted in each group produced a similar rank ordering to the other parameters examined, i.e. psoriasis psoriatic uninvolved normal.It was concluded that vascular mass and vessel dilatation was greatly increased in psoriatic lesions and to a lesser extent in the uninvolved skin of psoriatic patients, and it is believed that this helps confirm that the abnormality to the microvasculature in the skin of patients with psoriasis is not confined to the lesion.

    Prevention of doxorubicin-induced myocardial and haematological toxicities in rats by the iron chelator desferrioxamine (1992)

    Notes: Summary Biochemical and histopathological evaluations of the protective effects of the iron-chelator desferrioxamine against the cardiac and haematological toxicities of doxorubicin in normal rats were carried out. A single dose of doxorubicin (15 mg/kg, i. v.) caused myocardial damage that manifested biochemically as an elevation of serum cardiac enzyme [glutamic oxaloacetic transaminase (GOT), lactic dehydrogenase (LDH) and creatine phosphokinase (CPK)] and cardiac isoenzyme levels and histopathologically as a swelling and separation of cardiac muscle fibers. Doxorubicin caused severe leucopenia and decreases in red blood cell counts and haemoglobin concentrations at 72 h after its administration. Desferrioxamine treatment (250 mg/kg, i.p.) carried out 30 min before doxorubicin administration protected the heart and blood elements from the toxic effects of doxorubicin as indicated by the recovery of levels of cardiac enzymes and isoenzymes and of red blood cell counts to normal values and by the absence of significant myocardial lesions. The findings of this study suggest that desferrioxamine can potentially be used clinically to prevent doxorubicin-induced cardiac and haematological toxicities.

    Horseshoe lung: Differential diagnosis (1990)
    Springer
    Pediatric radiology 20 (1990), S. 580-584

    Notes: Abstract A detailed radiologic and anatomic study of one horseshoe lung syndrome has already been published from this centre. A further case of horseshoe lung, which was also diagnosed prospectively by radiology, is described. Alongside, this is a set of a group of three conditions: we describe a right accessory lung with a peculiar feeding arterial branch originating from the left basal pulmonary artery. The bronchogram and oesophagogram of this case were normal. The other is a case of bridging bronchus where the left lower lobe bronchus originates from the right main stem bronchus. This was discovered at post mortem bronchogram performed on a 19 weeks foetus. Finally, in the dog, we found that the pulmonary angiogram and bronchogram display close similarity to human horseshoe lung though the dog has two separate lungs. The common denominator of all above cases is the presence of a pulmonary arterial branch or bronchus crossing the midline from the ipsi to the contralateral side. Therefore, it may be concluded “in contradiction to the common belief” that pulmonary angiography or bronchography alone is not sufficient for the diagnosis of horseshoe lung. When only one of these investigations is savailable, computerized tomography is necessary to show the isthmic lung tissue before the diagnosis of horseshoe lung is confirmed.

    Chemical criteria for marine eutrophication with special reference to the Oslofjord, Norway (1992)

    Notes: Abstract Results of a chemical and geochemical study of the Oslofjord system are presented to explore the possibility of qualitatively identifying a eutrophication gradient. Nutrient concentration and dissolved oxygen may indicate such a gradient in areas of similar hydrographies. Uncertainties due to minor differences in hydrography may be resolved by considering sedimentary organic carbon, C:N ratios and the accumulation of mineralisation products in the sediment pore water. The reliability of the sedimentary organic matter and the pore water composition as gradient indicators can be impaired by input of terrestrial organics, dispersal of mineralisation products by the benthic fauna or the apparent high levels of organic carbon and pore water nutrients in the absence of the benthic fauna under anoxic conditions.
