OBJECTIVE Stoss vitamin D treatment has been recommended for its non-skeletal benefits in adults, but there is a lack of data on the optimal dose of vitamin D stoss therapy in children with vitamin D deficiency/insufficiency without rickets. This study aimed to compare efficiency/side effects of two different stoss therapy regimens (10 000 IU/kg and 300 000 IU vitamin D3) administered in childr...

Milk conservation and its organoleptic quality are greatly affected by different microbial contaminants (Table 1). These microorganisms are present either directly on the animal, in the farm environment or on the milking equipment. Industry requirements and country regulations require that the number of bacteria in raw milk be under a specific amount, often of 100 000 bacterial cells ml-1. Rece...

Interleukin-5 (IL-5) has been shown to be a selective eosinophil growth and differentiation factor. In the present study, the effect of recombinant human IL-5 on human eosinophil sulfidopeptide leukotriene production was investigated. IL-5 did not affect leukotriene synthesis in unstimulated eosinophils. However, IL-5 potentiated leukotriene synthesis by eosinophils stimulated with serum treate...

We retrospectively studied seven children (six girls, one boy) aged from 7.5 to 25 months who presented to our institution after taking large doses of vitamin D (900 000-4 000 000 U) prescribed by medical practitioners for wrong indications like failure to thrive, etc. The clinical manifestations were constipation, decreased appetite, lethargy, polyuria, dehydration and failure to thrive. All p...

Several experiments using a self-regulated system were conducted to define the factors likely to influence the uptake of paralytic shellfish poison (PSP) by oysters in the Penzé estuary (France, Brittany). Each 4-day experiment was carried out in a recirculated sea water system using 15 Pacific oysters (Crassostrea gigas) separated from each other and supplied with unfiltered natural seawater c...

Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth £5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand. It formed water blooms at densities >100 000 cells/ml in Lakes Waahi and Whangape. Net rates of population growth >0.2 day–1 were recorded for C. raciborskii i...
