Opis:: Despite the importance of calcium in many fruit species and the effects of calcium application, there is little or no reliable information on the effect of CaCl2 spray at different fruit development stages on the fruit mineral nutrient content during the growing season and at harvest. Therefore, this study has been conducted to evaluate the effect of calcium chloride (CaCl2, 15 g L-1) spray at different fruit development stages on the accumulation Ca and other macronutrients in cv. Hayward kiwifruit grown at two locations. In order to find the absorbality of Ca at different spraying times, fruits were harvested 7 days after a Ca treatment. Additionally, the mineral composition of kwifruit was determined at the stage of harvest ripeness. The results showed that the absorbality of Ca by kiwifruit from Ca spray decreased significantly with the progressing fruit development. The highest fruit Ca content was found when the fruit plants were sprayed at 35+80 DAFB and 35+80+120 DAFB, irrespectively of the location of an orchard. At a later Ca spraying application, the N content in kiwifruit significantly decreased, but the K and Mg content slightly increased. In contrast, the K/Ca, N/Ca, Mg/Ca and (K+Mg)/Ca ratios of CaCl2 sprayed fruits was lower than in the control and the ratio values were more balanced in the Ca treated fruit than in the control. Overall, three CaCl2 (15 g L-1) sprays could effectively improve the fruit quality by balancing the Ca ratio to other macronutrients. Therefore, Ca spray treatments could be a recommended treatment in growing cv. Hayward kiwifruit.

Tytuł:: Diagnostic values of calcium and magnesium forms determined in human serum and saliva

Opis:: Calcium and magnesium are known to be necessary for the normal function of various systems in animal and human organisms. There are many diseases caused by abnormal concentration of electrolytes, e.g. arterial hypertension or nervous system diseases such as multiple sclerosis, Mb. Alzheimer or Mb. Parkinson. The mechanisms of homeostasis indicate only the ionized forms of these elements. It is known that ionized calcium serves as an endocellular intermediary in action of enzymes and hormones in cells. Therefore, it is very important to define levels of total and ionized forms of Ca2+ and Mg2+ in blood serum and saliva by the method of atomic absorption spectrometry and to show their diagnostic value for various pathological conditions of a human body. The 39 persons, aged 21 to 47 years take part in these investigations. The results of determinations of calcium and magnesium forms present in human serum and saliva, representing physiological states are presented. The age and daily fluctuations of Ca2+ and Mg2+ content in serum and saliva were studied by atomic absorption spectrometry. The levels of non albumin forms of these elements were found by FAAS. The significance of determination of calcium and magnesium levels in serum and saliva under various pathological conditions (arterial hypertension and osteoporosis) was shown.
Wapń i magnez to pierwiastki niezbędne do prawidłowego funkcjonowania organizmów zwierzęcych i ludzkich. Istnieje wiele chorób wywoływanych przez nieprawidłowe stężenia elektrolitów, np. nadciśnienie tętnicze lub choroby układu nerwowego, takie jak SM, choroba Alzheimera lub Parkinsona. Mechanizmy homeostazy wskazują jedynie na zjonizowane formy tych pierwiastków. Wiadomo, że zjonizowana forma wapnia służy jako międzykomórkowy pośrednik między enzymami i hormonami w komórkach. Dlatego tak ważne jest określenie zawartości całkowitych tych pierwiastków oraz jonów Ca2+ i Mg2+ w surowicy krwi oraz w ślinie za pomocą metody absorpcyjnej spektrometrii atomowej oraz wykazanie ich roli w diagnostyce różnych stanów patologicznych w organizmie człowieka. Badaniami objęto 39 osób w wieku od 21 do 47 lat. W pracy przedstawiono wyniki oznaczeń form wapnia i magnezu występujących w ludzkiej surowicy krwi oraz ślinie odpowiadające stanom fizjologicznym. Wahania w zawartości Ca2+ i Mg2+ w surowicy i ślinie, w zależności od wieku i pory dnia, badano za pomocą aborpcyjnej spektrofotometrii atomowej. Zawartości niealbuminowych form tych pierwiastków określono za pomocą FAAS. Wykazano istotność oznaczeń zawartości wapnia i magnezu dla różnych stanów chorobowych (nadciśnienie tętnicze, osteoporoza).
