Background. Earlier we found that the newly created sulfate-chloride sodium-magnesium drinking mineral waters of Truskavets’ spa have similar neuroendocrine and metabolic effects on healthy old female rats significantly different from daily water. The aim of this study is to elucidate the effects of these mineral waters on the neuroendocrine status and metabolism of these animals. Materials and Methods. Experiment was performed on 50 healthy female Wistar rats. Animals of the first group remained intact, using tap water from drinking ad libitum. Rats of the control group for 6 days injected a tap water through the tube at a dose of 1,5 mL/100 g of body mass. The rats of the main groups received the water "Myroslava" and "Khrystyna". The day after the completion of the drinking course in all rats, at first, assessed the state of autonomous regulation by parameters of the HRV. The plasma levels of the hormones of adaptation were determined: corticosterone, triiodothyronine and testosterone (by the ELISA) as well as electrolytes: calcium, magnesium, phosphates, chloride, sodium and potassium; nitric metabolites: creatinine, urea, uric acid, medium molecular polypeptides, bilirubin; lipid peroxidation products and antioxidant enzymes, as well as cholesterol, amylase and glucose. Most of the listed parameters of metabolism were also determined in daily urine. In the adrenals the thickness of glomerular, fascicular, reticular and medullar zones was measured. Results. To identify exactly those parameters, the set of which all four groups of animals differ significantly from each other, the information field of the registered parameters was subjected to discriminant analysis. The program included in the model 8 endocrine and 16 metabolic parameters, information about which is condensed into three roots. The first root reflects directly the SOD and corticosterone and inversely the reticular zone as well as plasma uric acid and glucose. The second root contains information about Nap/Kp ratio, natrihistia, amylasemia, magnesiumuria as well as inversely about kaliemia. The third root reflects directly the triiodothyronine, parathyroid activity, plasma Ca, natriuria and chloriduria as well as urine malondyaldehide. Inversely displays the root information about the testosterone, Ku/Nau ratio, glomerular zone, plasma katalase and Na as well as uricosuria and amylasuria. In the information space of the three discriminant roots, all four groups are quite clearly distinguished. Classification accuracy is 94% (three errors). Conclusion. The newly created sulfate-chloride sodium-magnesium drinking mineral waters of Truskavets resort have specific endocrine and metabolic effects on healthy old female rats with weekly use. This provides a basis for preclinical studies.

Background. In order to expand the hydro-mineral base of Truskavets’ spa by diluting brine (130 g/L), two new sulphate-chloride sodium-magnesium mineral waters "Myroslava" (5 g/L) and "Khrystyna" (10 g/L) were created. This report is the first in a series of experimental studies of their physiological activity in line with the concepts of neuroendocrine-immune complex and functional-metabolic continuum. Materials and Methods. Experiment was performed on 50 healthy female Wistar rats 220-300 g divided into 4 groups. Animals of the first group remained intact, using tap water from drinking ad libitum. Rats of the control group for 6 days administered a single tap water through the tube at a dose of 1,5 mL/100 g of body mass. The rats of the main groups received the water "Myroslava" and "Khrystyna". The day after the completion of the drinking course in all rats assessed the state of autonomous regulation by parameters of the HRV. The plasma levels of the hormones of adaptation were determined: corticosterone, triiodothyronine and testosterone (by the ELISA); as well as electrolytes, nitric metabolites, lipid peroxidation products and antioxidant enzymes as well as cholesterol, glucose, amylase and middle mass molecules. Most of the listed parameters of metabolism as well as 17-ketosteroids were determined in daily urine. In the adrenal glands the thickness of glomerular, fascicular, reticular and medullar zones was measured. Results. To identify exactly those parameters, the set of which three groups of animals differ significantly from each other, the information field of the registered parameters was subjected to discriminant analysis. The program included in the model 6 endocrine and 11 metabolic parameters, as well as glomerular filtration. Conclusion. The newly created sulfate-chloride sodium-magnesium drinking mineral waters of Truskavets’ spa have similar neuroendocrine and metabolic effects on healthy old female rats significantly different from daily water.

The Impact

Background. Despite the long history, the results of studies of the impact of balneotherapy in the resort of Truskavets on the lithogenicity of urine are ambiguous, so the topic remains relevant. The aim of this study was to determine the relationship between the lithogenicity index of urine and a number of components of its composition. Materials and Methods. Experiment was performed on 60 healthy old female Wistar rats 220-300 g. Ten animals remained intact, using daily water from drinking ad libitum. Other animals for 6 days were loaded through the tube with daily and various mineral waters at a dose of 1,5 mL/100 g of body mass. The day after the completion of the drinking course collected daily urine, which determined the content of a number of components of the composition. We calculated urine lithogenicity index (Lith) by the formula: Lith = (Uric acid•Calcium/Magnesium•Creatinine)0,25. Results. The most significant effect on the Lith is the concentration of magnesium (r=-0,730), followed by uric acid (r=0,583), calcium (r=0,352) and creatinine (r=-0,298). Medium molecular polypeptides, catalase, sodium, phosphates and urea has been identified as prolithogenic factors while tubular reabsorption of water as litholytic factor. The chemical composition of the fluids consumed by animals has little effect on the lithogenicity index of urine. Conclusion. Both prolithogenic and litholytic factors are present in the urine, which depend little on the chemical composition of the fluid used.

Abstract Although simultaneous supplementation with iron and folic acid is justified, the potential interactions between these micronutrients are unknown. The aim of this study was to determine the effects of oral iron and folic acid, administered together or separately, on iron concentration in tissues in rats with a deficiency of both these micronutrients. In the first stage of the experiment (28 days), 150 8-week-old female Wistar rats were randomly assigned to a control group (C; n = 30) fed the standard diet and to a study group (n = 120) fed a diet deficit in iron and folate. The study group was then randomly divided to four groups: D group fed a deficit diet, FE group fed a deficit diet with iron gluconate, the FOL group fed a deficit diet with folate acid, and the FEFOL group fed a deficit diet with iron gluconate and folate acid. After 2, 10, and 21 days of supplementation, ten animals from each group were killed. Morphological parameters were measured in whole blood. Iron concentration was assayed in serum, liver, spleen, pancreas, heart, and kidneys. Folic acid supplementation more significantly decreased iron concentrations in the pancreas and spleen than in the D group after 10 and 21 days of supplementation. Moreover, the combination of iron with folic acid markedly decreased iron levels in the liver and spleen, in comparison with iron alone, after 10 and 21 days of the experiment. In conclusion, folic acid affects iron status in female rats deficient in these micronutrients in moderate and long-term supplementation.

Vascular bubble formation results from supersaturation during inadequate decompression contributes to endothelial injuries, which form the basis for the development of decompression sickness (DCS). Risk factors for DCS include increased age, weight–fat mass, decreased maximal oxygen uptake, chronic diseases, dehydration, and nitric oxide (NO) bioavailability. Production of NO is often affected by diving and its expression–activity varies between the genders. Little is known about the influence of sex on the risk of DCS. To study this relationship we used an animal model of Nω-nitro-l-arginine methyl ester (l-NAME) to induce decreased NO production. Male and female rats with diverse ages and weights were divided into 2 groups: treated with l-NAME (in tap water; 0.05 mg·mL–1 for 7 days) and a control group. To control the distribution of nitrogen among tissues, 2 different compression–decompression protocols were used. Results showed that l-NAME was significantly associated with increased DCS in female rats (p = 0.039) only. Weight was significant for both sexes (p = 0.01). The protocol with the highest estimated tissue pressures in the slower compartments was 2.6 times more likely to produce DCS than the protocol with the highest estimated tissue pressures in faster compartments. The outcome of this study had significantly different susceptibility to DCS after l-NAME treatment between the sexes, while l-NAME per se had no effect on the likelihood of DCS. The analysis also showed that for the appearance of DCS, the most significant factors were type of protocol and weight.

Background. The number of reproductive-aged women with cancer, who desire child bearing, has increased with improvements in cancer detection and treatment. Cancer treatments have the potential to cause germline mutations that might increase the risk of cancer in the progeny of cancer patients. the aim of the study was to assess the feasibility of reducing the long-term side effects of Etoposide on the progeny of rats using Glutaxim. material and methods. Forty-five white outbred female Wistar rats, 2.5-month-old, were divided into 3 groups. Group I consisted of 15 intact rats. Group II comprised 15 rats treated with cytostatic drug (the control group). Group III consisted of 15 rats treated with Glutoxim® (Glutayil-Cysteinyl-Glycine, Pharma Vam Ltd., Russia) at a dose of 50 μg/kg 5 days before and 5 days after receiving cytostatic drug. results. An increase in the number of fetuses with external hemorrhages and pathological changes in internal organs was found in the progeny of female rats receiving Etoposide 3 months before mating. The progeny experienced a decrease in the rate of formation of sensory-motor reflexes, ability to learn and adaptive behavior. All studied parameters did not differ from background values in the progeny of female rats treated with combination of Etoposide and Glutoxim. conclusion. Glutaxim is the effective drug for correction of pathological changes in the progeny of female rats receiving cytostatic drugs.

Purpose. Because thyroid hormones from the maternal thyroid glands are known to influence the growth, development, and metabolic functioning of offspring, we used a rat model to preliminarily investigate the effects of maternal hypothyroidism on glucose metabolism, pancreas cell proliferation, and insulin production in young male offspring and the possible underlying mechanisms. Methods. Female rats were divided into a maternal hypothyroidism (MH) group, which received water containing 0.02% 6-propyl-2-thiouracil before and during pregnancy to induce hypothyroidism, and a control group which consumed tap water. Results. Our results showed that there were no differences of islets structure between the offspring from the two groups, but glucose metabolism was impaired with higher plasma glucose concentrations at 0 and 15 min in the OGTT in 8-week-old offspring of the MH group. From birth to 8 weeks, pancreatic TRβ1 and TRβ2 mRNA level declined significantly in MH offspring, accompanied by decreased Ki67 and insulin mRNA expression. Conclusions. Maternal hypothyroidism results in impaired pancreatic insulin synthesis and pancreatic cell proliferation in neonatal offspring and subsequent glucose intolerance in young offspring, which may be related to TRβ gene downregulation in the pancreas.

The Impact

Introduction: Previous studies demonstrated that forced and voluntary exercise had ameliorative effects on behavioral tasks followed by Sleep Deprivation (SD) in intact female rats. The main goal of this research was evaluating the impact of voluntary exercise on cognitive functions while SD and ovariectomization is induced in female wistar rats. Methods: The rats were anesthesized combining dosage of ketamine and xylazine. Then, both ovaries were eliminated and 3 weeks after surgery the animals entered the study. The exercise protocol took 4 weeks of voluntary exercise in a wheel which was connected to home cage. For inducing a 72 hours deprivation the multiple platforms was applied. The cognitive functions were studied by exploiting the Morris Water Maze (MWM) and Novel object recognition tests. Anxiety was evaluated by open field test and corticostrone measurement was carried out by ELISA method. One-way and two-way ANOVA and repeated measures were utilized for data analysis and P<0.05 was considered statistically significant. Results: We observed significant spatial and recognition learning and memory impairments in OVX sleep-deprived rats compared to the control group and voluntary exercise alleviated the SD-induced learning and memory defects. Conclusion: We concluded that voluntary exercise can improve cognitive impairments followed by SD in OVX female rats.

ABSTRACT Background and objective Polycystic ovary syndrome (PCOS) can be induced in Wistar rats by over production of nitric oxide (NO). This study evaluated the efficacy of naloxone on the breeding characteristics of rats suffering from nitric oxide induced PCOS. Materials and methods Twenty-four female Wistar rats(200–250 gm) were kept as virgin under standard conditions. They were divided into four groups (n = 6). One group of the animals received L-arginine (50 mg/kg) intraperitoneally (i.p.) for 9 days/once a day. Another group was administered naloxone hydrochloride (0.4 mg/kg, i.p.) prior to injection of L-arginine. The third group was injected solely naloxone. Control group received saline solution (1 ml/kg, i.p.). After the treatments, all female rats were coupled with the intact males. They were then separated by observation of vaginal plaques; it was considered as day 0 of pregnancy. Eventually, they were operated on days 18 to 19 of the gestation to collect the animals’ ovaries. The samples were studied for pathological evidence. The fetal number and weight along with the fetal crown-rump length (CRL) were measured. Results The ovaries obtained from the L-arginine treated group had large cysts with thickened granulosa cell layer in contrast to those of the control or naloxone treated rats (p < 0.0001). The number of fetus though showed a decrease in the L-arginine treated rats (3 ± 1), but the fetal weight or fetal CRL did not change (p > 0.05). Conclusion This study may clearly illustrate the polycystic characteristics in the L-arginine treated group. It may particularly display the breeding efficacy of naloxone in rats with PCOS.

Objectives. Pharmacological and antifertility activity evaluation ofJatropha gossypifoliain rats.Methods. The antifertility activity of the extracts ofJatropha gossypifoliain rats was evaluated using two experimental animal models. Estrogenic activity was evaluated in immature female rats using ethinyl estradiol as standard. Anti-implantation and early abortifacient activity was performed in female Wistar rats by determining the number of implantations and implantation resorptions.Results. In estrogenic activity evaluations, the ethanolic and aqueous extracts offered significant estrogen-like activity at 400 mg kg−1p.o. by increasing the uterine weight compared to vehicle control group. Ethanolic extract (400 mg kg−1, p.o.) treatment significantly decreased the number of implants and increased the number of resorptions compared to vehicle control group.Conclusion. The results of the present study provide the evidence of the anti-fertility activity ofJatropha gossypifoliaas claimed in the traditional use. The results are consistent with the literature reports related to the antifertility effect of flower extracts ofJatropha gossypifolia.

This study was designed to evaluate the ameliorative role of betaine on hepatic and renal dysfunction caused by acrylamide in female rats. Thirty two (32) adult female rats were randomly and equally divided into four groups (G1, G2, G3 and G4) and were treated for (65) days as following: Group G1 (Control group), G2: rats were intubated 250mg/kg B.W of betaine; animals in group G3 were intubated 1mg/kg B.W of acrylamide, in addition to acrylamide. 250mg/kg B.W of betaine were administered orally to rats in groups G4. Fasting (8-12 hrs.) blood samples were collected by cardio puncture technique at the end of the experiment, serum were collected for measuring the following parameters A: liver enzyme makers; serum activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP)  B; renal function parameters including: serum creatinine, urea and uric acid concentration. The hepato and renal protective effect of betaine was clarified in groups (G2 and G4) manifested by significant decrease in serum, ALT, AST and ALP activity, as well as  significant decrease in serum creatinine, urea and uric acid concentration comparing to acrylamide (G3) treated group. Such functional changes were accompanied with structural (histopathological) alteration in hepatic and renal tissue. In conclusion, the results of the current study documented the negative effect of acrylamide on liver and kidney function and documented hepatorenal protective effect of betaine.
