I had originally thought of calling this piece, with a startlinglack of originality, ‘Forty years on’. It is after all exactly forty years since my own existing interests in African bibliography became formalised when I followed the option ‘Oriental and African bibliography’ at the School of Library Studies, University College London, taught by J.D. Pearson, the Librarian of the School of Oriental and African Studies. I later came to teach thisoption myself, from 1965 onwards, and indeed to follow Pearson by becoming the second to hold a chair entitled ‘Professor of the Bibliography of Asia and Africa in the University of London’. And in 2002 it will be forty years since SCOLMA (Standing Committee on Library Materials on Africa) was founded, the body that has done most in the U.K. to respond to the perceived needs of African bibliography, and one with which I have been associated for many years.

The Relationship

The development of Archigetes limnodrili in species of Limnodrilus is described. There is no free-living larva and eggs are ingested by the tubificids. Growth and development is completed within the body cavity of the annelid, and egg liberation is accomplished by release of the parasite and decay of its body.Breeding of A. limnodrili takes place throughout the year. In the localities investigated there was no evidence that a fish host was required in the life-cycle. Progenesis was the only type of development encountered in Britain.A. limnodrili exhibits an unusual degree of host specificity, being found only in species of Limnodrilus. It is suggested that this is due to differences in the composition of the coelom or intestine of Limnodrilus compared to other genera.The degree of infection in all localities is very low, and shows no regular seasonal variation. There is no similarity in the seasonal changes in different localities.The relationship between the host and parasite is a stable one, and there is little mutual damage. Factors contributing to this stability are discussed.The development of A. limnodrili is compared with that of other species of Archigetes, and the life-history discussed with particular reference to the phenomenon of progenesis.I wish to thank Professor R. J. Pumphrey in whose Department this work was carried out, and Dr J. C. Chubb for his constant advice and criticism. I also wish to thank Dr K. H. Mann and the University of Reading for provision of specimens and permitting me the use of their facilities. The work was carried out during the tenure of a Nature Conservancy Research Studentship.

In December, 1922, whilst dissecting a large female example of Bufo regularis, one of my students noticed a cylindrical structure extending along the ventral region of the body-cavity. A careful examination showed that this structure consisted of an elongated sac-like diverticulum of the right lung, containing an almost full-grown specimen of a dipterous larva, which could be seen through the membraneous wall of the diverticulum. The base of the latter, in addition to its point of origin from the lung, was also connected to the dorsal surface of the liver by strands of fibrous tissue, suggesting that the growth had been in existence some considerable time in order to cause such adhesions. Posteriorly, the diverticulum hung freely in the body cavity and extended to the extreme hinder end. Its dimensions were 5·5 cm. in length, by 0·5 cm. in diameter, but tapering towards each extremity.

Blood Sinus

In third and fourth instar larvae of Aedes aegypti (L.), juveniles of the rhabditoid, DD136, penetrate the blood sinus and cardial epithelium of the proventriculus to enter the body cavity of the host, where they complete their development. By 5 hours, a thick capsule developed about many of the ensheathed immature adults of DD136 within the body cavity of A. aegypti larvae. This rapid defence reaction of the mosquito to DD136, which has both a melanin and a cellular manifestation, occurs both in the exotic mosquito A. aegypti and in the two endemic species tested, Aedes stimulans (Walker) and Aedes trichurus (Dyar). The resistance of A. stimulans to an endemic rhabditoid, possibly of the Diplogasteridae, is also similar. The histological structure of the capsule is not affected during metamorphosis in A. aegypti; however, during histogenesis of adult tissue displacement and (or) distortion of some tissues and organs may be caused by the presence of the capsule within the host's body cavity. The activity of the adult A. aegypti is normal when this distortion or displacement is minor. Though usually encapsulated DD136 are retained within the body cavity of A. aegypti during metamorphosis, sometimes they are partially or completely expelled from the host's body cavity at the time of molting.

Leukemia is a cancer of the blood, where the body produces an overabundance of immature white blood cells. It is the most common childhood cancer and possibly originates from chemical exposure during fetal development. Understanding the molecular mechanism and causes of childhood leukemia will help the development of therapeutic and preventative strategies to reduce and treat occurrences of this cancer. Benzene is a non-polar aromatic ring that has been confirmed to cause leukemia in adults. Benzene metabolites can generate free radicals that could potentially be involved in the development of childhood leukemia through in utero exposures. It is found in tobacco smoke, gasoline, industrial solvents and many other substances. Pregnant mothers can be chronically exposed to these substances through daily activities. In order to help determine the mechanism of benzene toxicity, a study was performed to determine the presence of free radicals in the livers of fetal mice at gestation day 14. Fetal liver cell cultures were exposed to varying concentrations of benzene and additional cell cultures were exposed to various concentrations of a benzene metabolite mixture, composed of hydroquinone and benzoquinone. RNA was extracted from these cells and converted into complementary DNA. cDNA was then used in quantitative polymerase chain reactions to analyze a set of genes that are regulated by an antioxidant pathway. This pathway can be activated in response to oxidative stress, and a change in gene expression would indicate the presence of benzene or benzene metabolite toxicity in the liver at gestation day 14.

Histochemical Examination

1. Plerocercoid larvae of the pseudophyllidean cestode Ligula intestinalis from the body cavity of roach, were cultured in vitro at 40°C. in a variety of saline and nutrient media. About 65% of such cultures were aseptic. 2. During cultivation, larvae produced acid by-products (unidentified) and the pH fell rapidly. 3. The presence of these acid by-products slowed down development, or, if present in sufficient quantity, caused death. 4. In order to obtain development in nutrient media in a period (3 days) comparable to that required in a bird (the normal host) it was necessary to renew the medium 24-hourly. 5. 6% of the eggs produced from a worm cultured in horse serum were fertile. Fertile eggs were never obtained from larvae cultured in any other media. 6. Certain bacterial infections had no apparent detrimental effect on development, but others were toxic. 7. Some larvae underwent development in non-nutrient medium (¾ strength Locke's solution). The exact conditions under which this occurred was not determined. 8. Fragments (3 cm. long), of larvae or larvae with either scolex or posterior half removed, underwent development to the stage of oviposition in nutrient media. 9. Histochemical examination revealed that the plerocercoid larvae were almost fat-free. During cultivation, very large quantities of cytoplasmic fat were produced the quantity being proportional to the duration of cultivation. Fat was produced even under starvation conditions (i.e. during cultivation in saline) and can be considered a metabolic by-product. 10. The fresh plerocercoid contained great quantities of glycogen in the parenchyma and muscle regions. After cultivation in nutrient or saline media, considerable quantities were still present.

Although the web accessibility of universities around the world is well documented, much remains unknown about this aspect of higher education institutions in the UK. Using three automated web accessibility tools (TAW, WAVE and EIII Page Checker), this study explores the accessibility of the homepages of 66 research-intensive universities with respect to the WCAG 2.0 checkpoints. The results show that the most common checkpoint violations involve the provision of text alternatives for non-text content, contrast errors and the need to increase the computability of webpages with future technologies and tools. The results show that there are variations between UK universities, and there is some evidence of consistent compliance amongst the university homepages. However, when evaluated against results from similar studies of web accessibility in other countries, these web pages perform well. Overall, this study adds to the body of knowledge on web accessibility in higher education in the UK.

Clarias gariepinus were collected from Lake Chivero, Zimbabwe, and examined for nematode parasites from November 2000 to May 2002. Of the 202 specimens collected, 42.6 % were infected with third-stage larvae of Contracaecum sp. in the body cavity. The intensity of the infection was 1-7 worms per fish (mean intensity = 2.2). Seasonal variation in the prevalence of the parasite was not obvious and there was no significant difference in the prevalence of infection between males and females (c2 = 2.228; P > 0.05). No significant relationship between host size and prevalence was established. There was also no significant relationship between intensity and the body condition factor (r = 0.11; P > 0.05). The low parasite prevalence may have been caused by the disruption of the infection cycle since piscivorous birds, which are the final hosts of the parasite, do not feed on C. gariepinus in Lake Chivero.
