Ascorbic acid (AA) is a ubiquitous component of animal tissues which is sequestered by cells achieving very high concentrations not only in the neurohormonal secreting cells of the hypothalamus and in endocrine cells of the pituitary and adrenal glands but also in the acinar cells of salivary glands. The ascorbate-dependent processes occurring in salivary glands are not clear. We hypothesized that AA might have some physiological role in the secretory processes of neurotransmitters in...

Children under five years of age attending the Paediatrics Department, Gondar College of Medical Sciences, oral rehydration therapy (ORT) corner for acute diarrhoea in the year 1988-90 are analysed using only eight variables. Of 1003 children, 38.1% presented with no dehydration, 61.3% with some dehydration and 0.6% with severe dehydration. Eighty four percent of the children were below two years of age. Ninety seven per cent of the dehydrated children were managed with oral rehydration...

Various health education strategies have been observed to be practiced at the grassroots level in Malawi. One approach to communicate health knowledge and information in health education is by teaching people directly by a lecture that may be delivered at prearranged meetings. Generally, lectures stress the value of: good housing, good sanitation practice, personal hygiene, food and nutrition, child care, use of potable water, communicable disease control, and use of available health...

Dynamic and thermodynamic fields from ECMWF analyses have been presented for the tropical north African region for July 1989. Except for the region equatorward of 10°N, it has been shown that the pattern of mean low-level θe has a striking correspondence with the propagating storm statistics obtained from Meteosat in that region, with mean high θe corresponding to more propagating storm activity, and vice versa. Considerable correspondence is also found with the cold cloud duration pattern...

Following the observation of cases of haematuria among a secondary school population near Agulu Lake, an area not previously regarded as an endemic focus of schistosomiasis, a field study on urinary Bilharziasis was carried out among primary school pupils in the three towns surrounding Agulu Lake which was suspected to be the source of the infection. It was discovered that the area is an endemic focus of Schistosoma haematobium with prevalence rates ranging up to 77.6% among the primary...

A sexual behaviour study was conducted among 655 secondary school students to assess the association between sexual experience and non-sexual behaviours. Among students aged 15-19 years, the prevalence of nonvirginity increased with age, from 58.8% to 85.6% for males, and from 21.9% to 44.9% for females. Sexual experience correlated positively with measures of problem behaviours (r = .31) and negatively with a measure of church or mosque attendance (r = -.09). Overall, the relationship...

In an effort to optimize limited resources, a community‐based clinical pharmacy program was initiated to promote service, teaching, and research. This program sponsored the recruitment of pharmacy personnel to carry out distributive and clinical functions. This service enabled the development of new clinical attachment sites for pharmacy students. Students on these attachments carried out supervised projects that enhanced their learning while providing essential services to the community....

Key aspects of multicultural education and early African American scholarship are selectively examined to broaden, deepen, and refine our understanding of the link between the transformative nature of multicultural education and early African American scholarship. The exploration of the roots of multicultural education provides a basis for understanding contemporary issues in multicultural education within a historical context. Intellectual leadership is one of the most significant ways in...

Volcanic cycles of doming and eruption of the Miocene Kisingiri volcano produced three sedimentary cycles recorded in the volcaniclastic strata of Rusinga and Mfangano Islands, Lake Victoria, Kenya. Each of the three cycles began with the deposition of cobble and boulder conglomerates shed from the volcanically domed Precambrian basement, followed by deposition of pyroclastic and volcaniclastic strata, representing nephelinite-carbonatite eruption of the Kisingiri volcano. Volcanogenic...

Since 1980, most of the papers published on the El Asnam earthquake concern the geological and seismological aspects of the fault zone. Only one paper, published by Ruegg et al. (1982), constrains the faulting mechanism with geodetic measurements. The purpose of this paper is to reexamine the faulting mechanism of the 1954 and 1980 events by modelling the associated vertical movements. For this purpose we used all available data, and particularly those of the levelling profiles along the...

Two conventions tend to shape appraisals of the Belgian Congo and the manner of its decolonisation. The first describes the colonial power structure as an alliance of state, church, and large corporations. 1 This trinity was ‘not only… a virtually seamless web’, writes Crawford Young, ‘but each component, in its area of activity, was without peer in Africa in the magnitude of its impact’. 2 The second convention typically portrays decolonisation as tumultuous, chaotic, bungled, or simply...
