Public discussion around the accessibility of Artificial Reproduction Technology (ART) in Poland is not limited to considerations of the moral aspects of medical intervention into human fertility. Scientists of various disciplines get involved in these discussions as opponents to this form of procreation. Referring to research conducted all over the world, they suggest that children born thanks to the in vitro procedure are significantly more susceptible to all sorts of disease. The author, on the basis of available research data, shows that in reality worse health condition of in vitro-conceived children deals with a narrow number of well-identified disorders and in most cases is of correlative, not causative nature – mainly because weaker health of those children is usually connected with advanced age of the parents who choose IVF and their own state of health (mothers’ in particular), as compared to those who become parents in the natural way. The author also believes that loading the potential parents with anxiety about the health condition of their children should be treated as a delayed negative consequence of the ART methods application.

This article reports on a replication study of “Childless by choice? Attributions and attitudes concerning family size”, research published in Social Behavior and Personality and carried out by Valerie LaMastro in 2001. In the study presented in this paper the author examined the personality characteristics ascribed by naive perceivers to people with families of varying sizes. Students (N = 284) read one of twenty-four paragraphs describing a heterosexual couple who varied in the number of children they had (no children, one child, two children, six children) and in male and female employment status. Targets were rated on 28 personality characteristics and seven relationship quality statements concerning the level of family happiness. The results obtained indicated that a childless pair was viewed as less happy than those with children. Parents of any size family were, however, perceived similarly.

Absorption of calcium is regulated by many endogenous and exogenous factors. Prolactin is important regulator. Numerous studies indicate that prolactin can stimulate calcium transport in the small intestine in vitro and in vivo. This is especially important during the growing demand for calcium in pregnancy and in lactation. There is report the role of prolactin in maintaining calcium homeostasis.

PL

Wchłanianie wapnia regulują liczne czynniki endogenne i egzogenne, m.in. prolaktyna. Jak wynika z wielu badań, może ona stymulować transport wapnia w jelicie cienkim w warunkach in vitro oraz in vivo. Jest to szczególnie ważne w okresie wzrostu zapotrzebowania na wapń w okresie ciąży i laktacji. W licznych doniesieniach wskazano na rolę prolaktyny w zachowaniu homeostazy wapniowej.

Organ injury during ischemia is one of the clinical problems of today's transplantation. It occurs during warm ischemia time (WIT) when the blood flow is cut off and during cold ischemia when a graft is chilled in situ until the circulation is restored to the recipient organism. Fast cooling of the organ slows down metabolism and activates intracellular enzymes, which minimizes the effects of warm ischemia. Unfortunately, hypothermia also results in inhibition of ATP synthesis, cell swelling and intracellular acidity. That is why research is continually being conducted to develop new fluids for rinsing and storing organs, as well as to optimize the composition of those that are already in use, which will allow for longer and more effective graft storage and restoration of their optimal functions after transplantation. This article provides current information on rinsing and storage fluids available on the global market. It also discusses tips for the fluid modifications with hormones and micronutrients.

INTRODUCTION. Magnesium is one of the macroelements required to maintain normal body homeostasis. During studies, a positive effect in the prevention of cardiovascular disease, postmenopausal osteoporosis and diabetes was found. Unfortunately a deficiency of this element in the daily diet was observed, so supplementation is recommended. The aim of the study was to determine the influence of the kind of magnesium compound on the availability of Mg2+ with a tablet with an unmodified release rate. MATERIALS AND METHODS. The following preparations were used: Biomagnezja 150, Citromag B6 and Biomagnezja Plus (FZNP "Biochefa"). Examination of the release rate of the active substance was performed in a paddle apparatus at T = 37°C ± 0.5°C for 120 min., with a mixer at 50 revolutions/min. and using 0.1 mol/dm3 HCl (pH = 1.2). For analysis of the magnesium release, Statistica software with pharmaceutical extensions: Dissolution Profiles was used. RESULTS. Analysis of the tested products showed that the % of magnesium released increased in the following order: Biomagnezja Plus, Biomagnezja 150, Citromag B6 and was respectively 45%, 61% and 70 %. The release rate constant increased in the same order and it was respectively 0.0138 min-1, 0.0146 min-1, 0.018 min-1. CONCLUSIONS. The factors affecting the release of magnesium in vitro are the solubility of the compound, the presence of an inorganic anion or an organic ligand and the stability of the compound. A higher solubility makes a higher percentage of release. The presence of an organic ligand (hydrogen citrate) determines a greater percentage of the released dose in comparison with the magnesium oxide thereof.

WSTĘP: Magnez jest jednym z makroelementów niezbędnych do zachowania prawidłowej homeostazy organizmu. Stwierdzono jego pozytywne działanie w profilaktyce chorób sercowo-naczyniowych, osteoporozy pomenopauzalnej i cukrzycy. Niestety, obserwuje się niedobory tego pierwiastka w codziennej diecie, dlatego wskazana jest jego suplementacja. Celem badań było określenie wpływu rodzaju związku magnezu na dostępność farmaceutyczną Mg2+ z tabletek o niemodyfikowanej szybkości uwalniania. MATERIAŁ I METODY: Do badań wykorzystano preparaty: Biomagnezja 150, Citromag B6 i Biomagnezja Plus (FZNP „Biochefa”). Badanie szybkości uwalniania substancji czynnej wykonano w aparacie łopatkowym w T = 37°C ± 0,5°C, w czasie 120 min, przy 50 obrotach mieszadła/min, stosując 0,1 mol/dm3 HCl (pH = 1,2). Do analizy przebiegu uwalniania zastosowano program Statistica Zestaw Farmaceutyczny: Profile Uwalniania. WYNIKI: Analiza badanych preparatów wykazała, że procent uwolnionego magnezu wzrastał w kolejności: Biomagnezja Plus, Biomagnezja 150, Citromag B6 i wynosił odpowiednio: 45%, 61% i 70%. W takiej samej kolejności rosły stałe szybkości uwalniania: 0,0138 min-1; 0,0146 min-1; 0,018 min-1. WNIOSKI: Czynnikami wpływającymi na uwalnianie magnezu w warunkach in vitro są rozpuszczalność związku, obecność nieorganicznego anionu lub organicznego liganda i trwałość związku. Im większa rozpuszczalność substancji, tym wyższy procent uwalniania. Obecność liganda organicznego (wodorocytrynianu) determinuje większy procent uwolnionej dawki magnezu w porównaniu z jego tlenkiem.

The inappropriate supply of calcium influences bone loss and the risk of the osteoporosis. Health benefits expected from calcium depend on the amount of consumed calcium and also are strongly dependent on the possibility of organism to absorb calcium. Many studies devoted to this topic do not consider the absorbed calcium amount indeed which on average gives 10-75% of total calcium consumed. In order to make calcium absorption higher and more effective, researchers still conduct an investigation concerned with the factors enhancing calcium absorption and not having any negative influence on excretion of this element. The following can be rated among such substances: vitamin D, magnesium, inulin and other indigestible oligosaccharides, some amino acids, short-chain fatty acids, lactose, casein, phosvitin.

Nieodpowiednia podaż wapnia wpływa na utratę masy kostnej oraz ryzyko wystąpienia osteoporozy. Zdrowotne korzyści oczekiwane od wapnia zależą nie tylko od ilości spożywanego wapnia, ale również są bardzo silnie zależne od możliwości organizmu do wchłaniania przyjętego wapnia. Wiele badań poświęconych temu tematowi nie rozważa ilości wapnia rzeczywiście wchłanianego, która nigdy nie wynosi 100%, a waha się w granicach 10-75% w zależności od wieku i stanu zdrowia. Aby wchłanianie wapnia było jak najefektywniejsze poszukuje się substancji zwiększających absorpcję wapnia w przewodzie pokarmowym, a ponadto nie wpływających negatywnie na jego wydalanie. Do takich substancji można obecnie zaliczyć: witaminę D, magnez, inulinę i inneniestrawne sacharydy, niektóre aminokwasy, krótkołańcuchowe kwasy tłuszczowe, laktozę, fosfopeptydy kazeiny i foswityny.

Iodine deficiency is a common phenomenon, threatening the whole global human population. Recommended daily intake of iodine is 150 μg for adults and 250 μg for pregnant and breastfeeding women. About 50% of human population can be at risk of moderate iodine deficiency. Due to this fact, increased iodine supplementation is recommended, through intake of iodized mineral water and salt iodization. The aim of this study was to investigate permeation and absorption of iodide from iodine bioplex (experimental group) in comparison with potassium iodide (controls). Permeation and absorption processes were investigated in vitro using a porcine intestine. The experimental model was based on a standard Franz diffusion cell (FD-Cell). The iodine bioplex was produced using Saccharomyces cerevisiae yeast and whey powder: iodine content - 388 μg/g, total protein - 28.5%, total fat - 0.9%., glutamic acid - 41.2%, asparaginic acid - 29.4%, lysine - 24.8%; purchased from: F.Z.N.P. Biochefa, Sosnowiec, Poland. Potassium iodide was used as controls, at 388 μg iodine concentration, which was the same as in iodine-enriched yeast bioplex. A statistically significant increase in iodide permeation was observed for iodine-enriched yeast bioplex in comparison with controls - potassium iodide. After 5h the total amount of permeated iodide from iodine-enriched yeast bioplex was 85%, which is ~ 2-fold higher than controls - 37%. Iodide absorption was by contrast statistically significantly higher in controls - 7.3%, in comparison with 4.5% in experimental group with iodine-enriched yeast bioplex. Presented results show that iodide permeation process dominates over absorption in case of iodine-enriched yeast bioplex.

The aim of the study was to present the opinions on the leaflets attached to the packages of Over-the-counter (OTC) analgesics, taking into account the place of purchase and the usefulness of the information contained in the leaflet. The survey was conducted in Poland at the turn of February/March 2016 and June/July 2017. The authors constructed an original questionnaire consisting of 24 questions, both open and closed type. The survey was addressed to adults. In total 303 respondents were surveyed. Student t-test and Pearson’s chi-squared test were applied to determine differences between statistics, p < 0.05 was assumed as statistically significant. The respondents indicated a pharmacy as the main place of purchasing OTC analgesics. Most of the respondents declared that they read the leaflet attached to the package, and the font size used is large enough and legible. However, if it is difficult to read the information contained in it, and the majority of patients do not turn to the doctor or pharmacist for advice. The obtained results confirm that patients purchase and use drugs with increasing awareness. The study found that patients do not always understand drug information leaflets, and they do not always turn to professionals for counseling. The information contained in leaflets should be presented in a way that is clear, concise, and easily understandable to patients. It appears that the implementation of pharmaceutical care would greatly improve the safety of pharmacotherapy, including OTC non-steroidal anti-inflammatory drugs (NSAIDs).
