Sensory Profiles

Sensory profiles of saccharin, acesulfame K, aspartame, and neotame were compared with that of sucrose in three different types of water (tap water, commerical Crystalis water, and distilled water) under the conditions of the respective ISO standards. The intensities of off-flavours, especially bitter and metallic tastes, were higher in the solutions of synthetic sweeteners than in that of sucrose. The aspartame solution was the sample closest to the sucrose solution, and the intensity of off-flavours was significantly higher in acesulfame solution. Ratings of the bitter taste were related to those of the metallic taste, the relation being semilogarithmic. The performancies of different assessors were nearly the same in all ratings, and the absolute values of the ratings of sweetness and different off-flavours had the same repeatabilities. The relative accuracy was, naturally, much higher in off-flavours than in the case of sweetness.

The samples of mushrooms were collected in the forestry of the village Tyvriv and the town of Kalynivka, Vinnytsia and Kalynivka districts, in the conditions of Right-Bank Forest-Steppe of Ukraine. The studies of heavy metals concentration were performed in the scientific agrochemical laboratory of the Department of Ecology and Environmental Protection, the Faculty of Agronomy and Forestry at Vinnytsia National Agrarian University. The concentrations of Cu, Zn, Pb and Cd of the studied mushrooms were determined by the method of atomic absorption spectrometry after the dry mineralization. The research of the effect of culinary processing on the concentration of heavy metals in mushrooms were conducted according to the following scheme: 1. The control: mushrooms, cleaned and washed with tap water; 2. Option 1: mushrooms soaked in tap water for 3 hours and boiled in it; 3. Option 2: mushrooms soaked in the water without mineral residue for 3 hours and boiled in it; 4. Option 3: mushrooms soaked in distilled water for 3 hours and boiled in it. Summarizing the obtained results, it should be noted that the most effective way to reduce the concentration of lead and cadmium in mushrooms was the option of soaking and boiling mushrooms in the water without mineral residue. The most effective way to reduce the concentration of zinc and copper was Option 3, where distilled water was used. The influence of soaking and boiling mushrooms in different types of water is investigated. When soaking and boiling mushrooms in tap water for 3 hours, the concentration of zinc in them was found to decrease from 1.01 to 1.04 times, the concentration of copper – from 1.0 to 1.2 times, the concentration of lead – from 1.09 to 1.16 times and the concentration of cadmium – from 1.08 to 1.2 times. When soaking and boiling mushrooms in the water without mineral residue, the concentration of zinc decreased from 1.01 to 1.04 times, the concentration of copper – from 1.16 to 1.25 times, the concentration of lead – from 1.8 to 2.0 times and the concentration of cadmium – from 1.75 to 2.0 times. When soaking mushrooms and boiling them in distilled water, the concentration of zinc decreased from 1.13 to 1.18 times, the concentration of copper – from 1.2 to 1.29 times, the concentration of lead – from 1.22 to 1.28 times and the concentration of cadmium – from 1.08 to 1.2 times. Key words: mushrooms, concentration, zinc, copper, lead, cadmium, distilled water, water without mineral residue, tap water, boiling of mushrooms.

Inflammatory Pattern

An approach is presented to the study of cellular inflammation using cytological analysis of sputum in patients with bronchial asthma with different types of airway reaction to bronchoprovocation with cold air and distilled water. When the airways are hyperresponsive to hypoosmolar and cold stimuli, it has been established the activation of the neutrophilic component of bronchial granulocytes. Cold airway hyperresponsiveness is associated with an increase in neutrophil content and a concomitant decrease in the number of macrophages in the inflammatory pattern of the bronchi. An increase in sputum cytosis is inherent in a positive airway response to a hypoosmolar test with an unexpressed dynamics of the level of bronchial eosinophils.

The effects of an aqueous supernatant of haruan (ASH) (Channa striatus) fillet extract on various antinociception receptor system activities were examined using a mouse abdominal-constriction model. Mice that were pretreated with distilled water, s.c., followed 10 min later by administration of 25%, 50%, and 100% concentration ASH, s.c., produced a significant concentration-dependent antinociceptive activity (p < 0.001). Pretreatment with naloxone (0.3, 1.0, and 3.0 mg/kg body mass), 10 min before ASH administration, failed to block the extract antinociception. Pretreatment of the 100% concentration ASH with mecamylamine (5 mg/kg), pindolol (10 mg/kg), and haloperidol (1 mg/kg) also did not cause any significant change in its antinociception. However, pretreatment with atropine (5 mg/kg), bicuculline (10 mg/kg), phenoxybenzamine (10mg/kg), and methysergide (5 mg/kg) were found to reverse ASH antinociception. Based on the above findings, the ASH is suggested to contain different types of bioactive compounds that act synergistically on muscarinic, GABAA, α-adrenergic, and serotonergic receptor systems to produce the observed antinocicep tion.

The aim of this study was to evaluate the influence of six wetting levels of the substrate on the germination of Centaurea sp., Petunia sp., Convolvulus sp., Dhalia sp., Adonis sp. and Chrysanthemum sp. ornamental species. Two experiments were carried out in the Laboratory of Plant Physiology, Universidade Tecnológica Federal do Paraná - Campus Dois Vizinhos. In the first experiment, the experimental design was in randomized blocks, in a factorial 6 x 6 (ornamental species x water volume), with four replications of 50 seeds. In the second experiment, the delineation differed by the absence of the use of Dhalia sp. Seeds. The first and second experiment had their substrates moistened uniformly with addition of distilled water at six different quantities, 0, 100, 150, 200, 250 and 300 mL per 100 g of Vermiculite® on the experiment 1 and 400 g of Mecplant® in experiment 2. The germination percentage and emergence rate index were evaluated after 14 and 21 days of sowing, in experiments 1 and 2, respectively. With the use of Vermiculite® it was recommended for Dhalia sp. and Chrysanthemum sp. all the water volumes tested; for Petunia sp. above 150 mL, for Convolvulus sp. 200 and 250 mL of water and for Centeaurea sp., 150 and 200 mL of water. The use of the substrate Mecplant® it was recommended for Chrysanthemum sp., Convolvulus sp., Centeaurea sp. and Petunia sp. In all of the volumes of water tested. For Adonis sp., regardless of the substrate used, other studies will be necessary, since that didn’t occurred germination, what can be related to some dormancy.

The electrical conductivity test is a quick, practical and objective test force; however, its effectiveness varies according to the species, quantity of seed, water volumes, soaking temperature, among other factors. The objective of this study was to evaluate the physiological quality of P.moniliformis seeds lots by means of the electrical conductivity test, testing different methodologies. For this, two lots were tested in three quantities of time (25, 50 and 75 seeds) and nine soaking times (2, 4, 6 , 12, 24 , 36, 48, 60 and 72 hours) in three volumes of water (50, 75 and 100 mL) at 25 °C. To evaluate the initial quality of the lots, germination percentage, germination speed index, average time of germination, length and dry mass of seedlings were determined. The use of the electrical conductivity test of P. moniliformis seeds is recommended using 75 seeds in 75 mL of water for 2 hours at 25 °C or seeds in 50 mL distilled water with 50 seeds per 6 hours at 25 °C.

The aim of this work is the investigation of zeta-potential of the mineral scheelite from mine 'Rudnik', located in central Serbia. Electrophoresis measurements using zeta-meter were carried out on four different types of water, namely: tap water, distilled water, rain water and spring water. All types of water had different hardness and conductivity as well as natural pH values. It was found that the zeta-potential of mineral scheelite depends on the hardness and electro-conductivity of the chosen type of water as well as on Ca2+ content. The results obtained reveal the importance of proper choice of water as well as the type of reagents for flotation processes.
