<p>Nowadays, tourism is present as a dynamically developing sector in many areas of the world, which is an outstanding example of the interaction between the resources offered by the natural environment, and people. As in many countries of the world, medical tourism based on natural healing factors is also of special economic and social importance in Hungary. The natural healing factors and the medicinal water treatment facilities based you them are available in different quantities and qualities in different areas of Hungary. These regional differences, as well as the changes in health and medicine tourism trends that happened in the last years, call attention lake the modern planning of the development of the affected settlement especially the spa towns, which is essential for the harmonious and sustainable relationship of the natural environment and people.</p> <p>Our research aims to light the importance of territory differences in Hungarian natural resources medical tourism factors, as well as to map and define the territorial inequalities of the most significant medical tourism factors, for which we apply the methods of regional research. Our results, calculated with the indicators of territory polarization and territoriality distributions, show that the Hungarian medicinal water supply is relatively even from a territory point of view, while the other natural healing factors show significant territorial inequality and concentration. In the case of medical facilities, we measured low territorial inequality and concentration at the medicinal baths, while we observed relatively significant territorial inequality and concentration at the NEAK (National Health Insurance Fund) contracted medicinal water treatment facilities.</p> <p>From the results we obtained, we came lake the conclusion that the territorial differences in natural healing factors created by natural influences lower have a significant impact you the built environment, which lower generates social and economic differences through medical tourism. These territorial differences and effects must be kept in mind during the planning and development of Hungarian spa resorts involved in medical tourism.</p>Ágnes Erzsébet Hojcska Zoltán SzabóZoltan Bujdoso

https://czasopisma.uwm.edu.pl/index.php/pjns/article/view/10246
<p>Biological rhythms control many physiological and behavioral functions in mammals, including reproduction. During the development of the reproductive system, testicular growth is primarily influenced by photoperiod, which is influenced by the circadian release of melatonin. The purpose of this study was to determine the effect of darkness on the gonadotropic axis in mature male rabbits. This study used ten male rabbits separated into two groups : a control group and a group that was placed in complete darkness for 15 days. After the sacrifice, using the IRMA method, blood samples were collected to assess serum LH and FSH hormone levels. Histopathology (testis) parameters were investigated and sperm smears were also obtained in order to investigate the morphological structure of the sperm collected. The results revealed morphological alterations in treated rabbits as well as a significant decrease in blood FSH and LH levels when compared to controls, suggesting a relationship between the gonadotropic axis and the pineal gland. The results of this study reveal that factors that activate the gonadotropic axis, such as darkness, can cause alterations in reproductive function, and that this is also dependent on photoperiod duration.</p> <p> </p>Samira Akdaderlynda LakabiAssia KamelZohra Hamouli-Said

https://czasopisma.uwm.edu.pl/index.php/pjns/article/view/8762
<p>Two hundred and eight (208) day-old Cobb chicks hatchery-infected with <em>Eimeria </em>were divided into four treatment groups and administered: control (0), 50 ,100 and 150 grams of <em>Lagenaria breviflora</em> R. (Lb) whole fruit per litter of water thrice a week for 6 weeks. Data were obtained on faecal count, haematological indices, serum metabolites and stress biomarkers. There was reduction in <em>Eimeria</em> count as Lb increased with the highest reduction (85.20%) in 150 g. The highest (<em>P</em> < 0.05) packed cell volume, haemoglobin and red blood cell count was observed in 150 g while white blood cell count was highest (<em>P</em> < 0.05) in 50 and 150 g. Total protein was highest (<em>P</em> < 0.05) in 150 g, globulin was highest in 100 and 150 g LB while the serum stress biomarkers (SOD and GSH-Px) was least in 50 g. The use of Lb up to 150 g can used in eradicating coccidiosis without compromise on health of birds.</p>Deji EKUNSEITANOluwabamise V. OdubelaRidwan A. AhmedOluwaseun S. IyasereBoluwatife A. Adeniran

https://czasopisma.uwm.edu.pl/index.php/pjns/article/view/10712
<p><strong>Abstract</strong></p> <p>The chemical, mineral, and antioxidant content of two different species(yellow & green) of young coconut water in Trinidad and Tobago was quantified and compared coconuts The Total phenolic content (TPC),2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, Total soluble solids (TSS), Titratable acidity (TA), pH, turbidity, and mineral assay were tested Data obtained showed tentative concentrations of minerals, chemical properties, and antioxidant activity. The green (Atlantic tall) coconut water showed higher antioxidant activity with the DPPH and TPC assays compared to the yellow (Malayan dwarf) coconut water (p< 0.05). The yield of the crude extract was slightly higher in the yellow coconut water (p>0.05). No significant difference was observed in Total soluble solids (TSS) and pH between the two-coconut water (p>0.05). The titratable acidity of the green coconut water was higher (p<0.05). The yellow coconut water was more turbid (p<0.05). The yellow coconut water was higher in Na, K, Ca, and Mg (p< 0.05) but showed no significance in Fe between the two (p>0.05). This indicates that coconut water from Trinidad and Tobago contains high minerals and antioxidants.</p>Sani Ismaila
