[Mineral elements in diet of pregnant and breast-feeding women. Part II. Micro minerals: iron, zinc, copper, selenium, iodine, fluorine, manganese, molybdenium, chromium].

The first article describes in detail problems connected with the role of macro minerals: Ca, Mg, P, Na, K, Cl in the diet of pregnant and breast feeding women. We concentrated on the choice of good natural sources of micro minerals: Fe, Zn, Cu, Se, I, F, Mn, Mo and Cr. The amounts of the elements in some of the food products are listed and factors that decide on their bioavailability are described.

[Mineral elements in diet of pregnant and breast-feeding women. Part I. Macro minerals: calcium, magnesium, phosphorus, sodium, potassium, chloride].

During pregnancy and lactation the need not only for the energy intake increases but also for some mineral elements. The basic source of mineral elements and other chemical elements for the human organism is food. For the increased need for minerals, proper selection of food products is vital and sometimes extremely difficult to do.

[Food products as a natural source of vitamins for pregnant women].

Although diet of pregnant women very often require supplementation with proper vitamins, food should be the basic source of them. Different food products consist of different amounts of vitamins. That is why the proper choice of natural sources of vitamins seem while to be the most important white preparing a diet.

Activated leukocytes and endothelial cells enhance retention of ultrasound contrast microspheres containing perfluoropropane in inflamed venules.

Purpose: To characterize the flow dynamics of albumin ultrasound contrast microspheres containing perfluoropropane (PFP) in normal and inflamed microvasculature.

Materials And Methods: Mesenteric microvessels of rats were examined after an intravenous injection of fluorocein-labeled erythrocytes or PFP microspheres by fluorescence intravital microscopy with and without local application of 10(-8) M platelet activating factor (PAF) as an experimental form of inflammation.

Results: All the microspheres passed freely through arterioles and capillaries.
