Intestinal transit accelerates during gastroduodenal haemorrhage. To test a personal theory that the reason is to be found in serotonin released by platelets and absorbed by the intestine, the behaviour of serotoninaemia has been studied. This proved to be 1.35-9.7 microgram/l (mean: 4.175 microgram/l; E.S. +/- 1.39) in patients with haematemesis and melena, compared to 0.49-0.9 microgram/l (mean: 0.728 microgram/l; E.S. +/- 0.07) in the controls (p less than 0.001). The increase in circulating serotonin to significant values is probably due to hormone release. This dose not occur in cases of melena alone, probably owing to the organism's high capacity for catabolism.

Bracken fern (Pteridium spp.) is a highly problematic plant worldwide due to its toxicity in combination with invasive properties on former farmland, in deforested areas and on disturbed natural habitats. The carcinogenic potential of bracken ferns has caused scientific and public concern for six decades.

After World War II, large amounts of ammunition were dumped in surface waters worldwide, potentially releasing harmful and toxic compounds to the environment. To study their degradation, ammunition items dumped in the Eastern Scheldt in The Netherlands were surfaced. Severe damage due to corrosion and leak paths through the casings were observed, making the explosives in the ammunition accessible to sea water.

Thalassemia is the most prevalent single gene defect in human beings worldwide. Repeated blood transfusions along with chelation therapy are mainstay of treatment in thalassemia patients. However these recurrent blood transfusions result in iron overload which along with chelation therapy causes deterioration of liver function.

Glyphosate is the best-selling herbicide worldwide. The toxicity on ecosystems and the possible effects on human health have long been at the centre of a complex controversy concerning the authorisation for its use. The peculiar chemical-physical properties of glyphosate, AMPA and glufosinate make their determination at trace levels in the water a real analytical challenge.

Background: Despite interventions, childhood anemia is still a major public health problem in low and middle income countries. Purpose of the present study is to determine factors associated with anemia among rural primary school children in Sri Lanka, a country undergoing rapid socioeconomic changes.
Methods: Multi stage cluster sampling was used to select 100 rural schools in NCP and a maximum of 50 children aged 60-131 months were enrolled from each school.
