This chapter looks at two diseases affecting the vascular system of the cacao tree: vascular streak dieback, caused by the fungus Ceratobasidium theobromae, and wilt disease, caused by the fungus Ceratocystis cacaofunesta. Both diseases are considered as serious threats to cacao production and their impact has already been considerable and severe. Vascular streak dieback nearly destroyed the cacao industry in Papua New Guinea and is mercifully restricted to Indonesia, Malaysia, and South-East Asia, while Ceratocystis wilt has been reported in several countries in South and Central America, where it has caused substantial crop losses. The chapter examines the research being undertaken to better understand these diseases and how best to tackle them.

The theory that American aboriginal civilization was derived from south-east Asia and indirectly from Egypt has received such wide publicity that it is no longer possible to dismiss it lvithout refutation and wait for it to die a natural death. Such was the policy followed when the extravagances of Lord Kingsborough claiming that the inhabitants of Central America were the lost ten tribes first saw the light. Le Plongeon's fantastic claims too had their hour and then passed into the limbo of lost causes. Other heads of this hydra, peopling Central America from the lost continent of Atlantis, from Babylonia, Africa, New Zealand, Easter Island, and in fact from nearly every quarter of the globe, were not lopped off but left to wither away from lack of that blood, so necessary to this type of hydra–reasoned argument and proof.


Three years ago the Royal Society held a two-day discussion meeting entitled ‘Technologies for Rural Health’. The meeting was well attended, the choice of subject appeared to meet a need and many of those who spoke expressed a wish that another such meeting might take place in a few years’ time. The Society has responded and today and tomorrow we shall be discussing ‘More technologies for rural health’. This is not, however, merely a repeat performance by popular demand. It is an attempt to focus on the dominant points that emerged from the 1976 discussions in seeking to alleviate the burden of ill-health, disease and malnu­trition among the three-quarters of the world’s population who live in rural areas. Early in the programme we have placed water and sanitation, and agri­ culture and nutrition - the same priority as was given in the 1976 meeting, but during the 3 years that have elapsed the solving of the relevant problems has become more urgent and, in many cases, the problems have themselves become more complex. An example of a specific complexity is that of refugees. The forces creating refugees have rarely been absent but, in recent months, these forces have been especially active in Central America, in Africa and in Asia. I introduce this complexity to the problems of rural health with particular feeling. I have just returned from a visit to south-east Asia and was in Bangkok when the Prime Minister of Thailand announced that he had changed his mind about his country’s policy with regard to the refugees on their border with Kampuchea. The Thailand frontier would now be open to the tens of thousands of refugees seeking sanctuary, a decision obviously putting humanitarian motives before the interests of national security and public health.

Abstract The production of sticky threads from spinnerets is known from various myriapod groups including some representatives of the millipedes (Diplopoda). In Diplopoda the thread-producing glands are mostly seta-like and positioned terminally on the telson, and the secretion product is typically used to build molting chambers or egg sacs. So far, no such secretions or organs have been documented for the subgroup Pentazonia. Here we describe thread-producing glands from the species-poor Glomeridesmida. These putative spinning organs are single circular fields of small pores (spinning fields) positioned on the outer side of the tarsi of all walking legs of mature and juvenile individuals of both sexes. These pores are the openings of cuticular tubuli (conducting canals), which extend from the tarsus to an aggregation of cells, a putative gland, within the femur. In several specimens thin threads were observed to be extruded from the pores. The tarsal spinning fields are present in all 21 investigated Glomeridesmida morphospecies, including Termitodesmidae and Glomeridesmidae from South East Asia, the Indian subcontinent, Oceania, and South and Central America. These organs might constitute an apomorphic character of the Glomeridesmida, as similar organs are absent in other Myriapoda. The function of the extruded threads in Glomeridesmida remains speculative, because observations of living specimens of the group are almost non-existing. We suggest that the secretion might be used for defense, to build molting chambers or to secure tunnels burrowed in the substrate.

Although undisturbed tropical evergreen forests are often thought to be fire- resistant ecosystems due to lack of sufficiently dry fuel loads (Bond & van Wilgen 1996, Kauffman et al. 1988, Uhl et al. 1988), this myth is rapidly collapsing with the proliferation of recent forest fires throughout south-east Asia (Kinnard & O'Brien 1998, Leighton & Wirawan 1986), Central America (Anon. 1998a), and northern South America (Anon. 1998b) following unusually severe seasonal droughts.

To determine the immunization status of pediatric patients under age of 5 years visiting pediatric department of tertiary care hospitals in South East Asia. The aim of this study was to appreciate the awareness and implementation of vaccination in pediatric patients who came into pediatric outpatient Department with presenting complain other than routine vaccination. we can also know the count of patients who do not complete their vaccination after birth. we can differentiate between vaccinated and unvaccinated patients and incidence of severe disease in both groups. Immunization is a protective process which makes a person resistant to the harmful diseases prevailing in the community, typically by vaccine administration either orally or intravenously. It is proven for controlling and eliminating many threatening diseases from the community. WHO report that licensed vaccines are available for the prevention of many infectious diseases. After the implementation of effective immunization the rate of many infectious diseases have declined in many countries of the world. South-East Asia is far behind in the immunization coverage. An estimated total coverage is 56%-88% for a fully immunized child, which is variable between countries. Also the coverage is highest for BCG and lowest for Polio.

It had long been believed that none of the bird, egg or nest specimens that had been in the collection of Sir Hans Sloane at his death in 1753 had survived. However, a specimen of a rhinoceros hornbill, originally in Sloane's hands, was discovered in the Natural History Museum's collections in London in 2003, and three more Sloane hornbill specimens have subsequently come to light. In addition, we report here a most unexpected discovery, that of the head of a woodpecker among the pages of one of Sloane's bound volumes of pressed plants. The context suggests that the head, like its associated plant specimens, was probably collected in south-east Asia about 1698–1699 by Nathanael Maidstone, an East India Company trader, the material reaching Sloane via William Courten after the latter's death in 1702. A detailed description of the head is provided, along with observations on its identity and possible provenance.
