Short-time Ingestion of Colas Influences the Activity Distribution at Bone Scintigraphy: Experimental Studies in the Mouse

Background: A negative effect of soft drinks, especially phosphate containing colas, on bone mineral contents has been reported. Most studies have been epidemiological investigations or performed in healthy humans.

Objective: The aim was to study the effect of short-time ingestion of Coca-Cola®, a phosphate containing soft drink, and of Fanta®, a non-phosphate containing soft drink, in a murine system for bone scintigraphy. This technique may be used to study bone metabolism.

Design and Methods: After feeding the beverages to the mice during different time periods (2 h to 6 days), the animals were injected with the bone-seeking radiopharmaceutical. The activity distribution was thereafter mapped by dissecting the hind legs and different soft tissue organs and assessing their activity with a gamma-counter. Controls were mice drinking water.

Results: After drinking Coca-Cola® there was a significantly increased bone uptake of the tracer and a reduced uptake by most soft tissues versus controls. After Fanta® there were no differences. Comparing Coca-Cola® and Fanta®, there was a significantly lower uptake by all soft tissues after Coca-Cola®, but no significant difference for bone.

Conclusions: Short-time ingestion of Coca-Cola® in mice causes an increased bone uptake and a reduced soft tissue uptake at bone scintigraphy. There may be a similar, weaker effect by Fanta®. This is in agreement with previous studies indicating that soft drinks may, on their own, have a metabolic effect on the bone.

Three potential sources of microfungi in a treated municipal water supply system in sub-tropical Australia

Some microfungi are known to be opportunistic human pathogens, and there is a body of scientific opinion that one of their routes of infection may be water aerosols. Others have been implicated as causative agents of odours and off-tastes in drinking water. This study was undertaken to investigate three potential sources of microfungi in a treated, oligotrophic municipal water supply system in sub-tropical Australia. Formation of the microfungal component of developing biofilm on hard surfaces in water storage reservoirs was also assessed. Inside and outside air samples were collected from two reservoirs using two types of Burkard air samplers. Biofilm and soft sediment samples were collected from the inner surfaces of asbestos cement water pipes and from pipe dead ends respectively. These were analysed for microfungal growth and sporulation using Calcofluor White stain and epifluorescent microscopy. Artificial coupons of glass, PVC and concrete were immersed in two reservoirs to assess microfungal biofilm formation. This was analysed periodically using Calcofluor White stain and epifluorescent microscopy, cultures of coupon swabs and scanning electron microscopy. Fungal spores were recovered from all air samples. The number of colonies and the genera were similar for both inside and outside air. Microfungal filaments and sporulating structures were recovered from most of the pipe inner surface biofilm and dead end sediment samples, but were sparser in the biofilm than in the sediment samples. No recognisable, vegetative filamentous fungi were found in the slowly developing biofilm on coupons. This study indicates that airborne spores are an important potential source of microfungi found in water storage reservoirs. It has also demonstrated conclusively that filamentous microfungi grow and sporulate on water pipe inner surfaces and in soft sediments within the water distribution system.     

Does the provision of cooled filtered water in secondary school cafeterias increase water drinking and decrease the purchase of soft drinks?

BACKGROUND: Secondary school students often do not drink sufficient quantities of water during the school day to prevent dehydration, promote learning and good health. The study aimed to measure the effect of health promotion and the free provision of cooled filtered water on the consumption of water and soft drinks. It also aimed to explore students' views of drinking water provision. METHODS: A study was conducted with three secondary schools in North Tyneside. Over a 3 month period one school was given cooled filtered water and active promotion (W + P), another had water only (W). The control school (C) took part in post-intervention focus group work. RESULTS: The average volume of water drunk by students, in school 'W + P' was greater (P = 0.05) than that drunk in school 'W' and control school 'C'. The volume of soft drinks purchased by students in all three schools before and during the intervention remained static. Focus group data revealed that students viewed their existing water provision as poor and wanted sufficient supplies of cooled filtered water in school. CONCLUSIONS: This pilot study indicates that active promotion of water drinking increased consumption of water by secondary school students. Further developments of the project are suggested.

The incidence of anencephalus in the Fylde peninsula 1956-76 and changes in water hardness.

In an area which had a high incidence of anencephalus, 3.2 per 1000 births, there was a significant drop to 1.3 per 1000, below the national average of 1.7 to 1.8, among conceptions after 1967. In the northern part of the area this drop was greater in summer than winter conceptions, providing additional evidence of a different process underlying case occurrences in the north of the area from that in the south. In 1957-61 there were significantly more births of anencephalic babies in North Fylde than in South Fylde, but both areas were supplied with soft water. From 1962 to 1969 the water changed from soft to slightly hard. Soft water does not appear to be a primary aetiological factor in anencephalus, but hard water may mitigate the effect of other factors.
