The aim of this study was to investigate the clinical efficacy of vanadium complexes on triglycerides (TG), total cholesterol (Chol), uric acid (UA), urea (U), and antioxidant parameters: nonenzymatic (FRAP—ferric reducing ability of plasma, and reduced glutathione—GSH) and enzymatic (glutathione peroxidase—GPx, catalase—CAT, and GPx/CAT ratio) activity in the plasma of healthy male Wistar rats. Three vanadium complexes: [VO(bpy)2]SO4⋅2H2O, [VO(4,4′Me2bpy)2]SO4⋅2H2O, and Na[VO(O2)2(bpy)]⋅8H2O are administered by gavage during 5 weeks in two different diets such as control (C) and high fatty (F) diets. Changes of biochemical and antioxidants parameters are measured in plasma. All three vanadium complexes statistically decrease the body mass growth in comparison to the control and fatty diet. In plasma GSH was statistically increased in all vanadium complexes-treated rats from control and fatty group in comparison to only control group. Calculated GPX/CAT ratio was the highest in the control group in comparison to others.

Acute And Chronic Exposure

Intoduction: Acute and chronic exposure to toluene at high doses is known to affect all organs of the body including the spermatogenesis process. In the industrial sector, the use of toluene as a solvent is still widely used, up to 10 million tons per year. The control over health problems that may occur is carried out by applying work exposure threshold values. This research aims to explore the effect of toluene exposure at the threshold value range on spermatogenesis.Method: This research used laboratory experiment on 30 male Wistar rats which were divided into five groups of different exposure levels, namely 12.5 parts per million (ppm], 25 ppm, 50 ppm, 100 ppm, and no exposure (control). Exposure was given for 4 hours daily over 14 days through a hood with measured release in the glass cage. The toluene exposure markers observed were Malondialdehyde (MDA) in the blood tissue and testicles using the Thiobarbituric Acid Reactive Substances (TBARS) method. The effect on the spermatogenicity process was assessed by counting the spermatogonia A cells of male Wistar rats with Periodic Acid Schiff (PAS) staining and is calculated by the Abercrombie formula. Analysis of the correlation between the level of exposure and its effect on the increase in malondialdehyde, and spermatogenesis was carried out using the Spearman correlation analysis.Result: There was a moderately positive correlation between levels of toluene exposure and plasma MDA levels (r = 0.42; p = 0.025). Meanwhile, on [the issue of] the quantity of spermatogonia cells, a high level of negative correlation with exposure levels was obtained (r = -0.68; p = 0.001).Conclusion: Toluene exposure in male Wistar rats within the range of threshold values influenced the increase in plasma MDA levels and decreased the Spermatogenia A cells. However, toluene exposure did not affect the testicular MDA levels of male Wistar rats.

The purpose of this study was to prove that the administration of Jati (Guazuma ulmifolia Lamk) leaves extract improves the lipid profile of dyslipidemic male Wistar rats. Subjects were 20 rats (Rattus norvegicus), male, Wistar strain, dyslipidemia (total cholesterol ≥ 200 mg dl-1), aged 2 months old, weighing 180-200 grams. The control group (10 rats) were given a placebo of 3 ml aquadest (P0) and the treatment group was given extracts of the Jati (Guazuma ulmifolia Lamk) leaves extract of 25 mg kg-1 BW (P1). Before and after treatment for 14 days, total cholesterol, triglyceride, LDL, and HDL levels were examined. The results showed that in the P0 group there were no changes in total cholesterol, triglyceride, LDL, and HDL levels (p>0.05), whereas the P1 group experienced a decrease in total cholesterol, triglyceride and LDL levels (p<0.05) and an increase in HDL levels (p<0.05). The results of this study indicated that the Jati leaves extract was effective to improve the lipid profile of dyslipidemic rats. It was necessary to compare the effectiveness of Jati leaves extract with synthetic dyslipidemia drugs used in the community such as statin.

Background: A high prevalence of chromium and benzene compounds in the environment associated with motor vehicle and industrial operations arouses interest in the study of these xenobiotics in a long-term experiment. The objective of this work was to analyze effects of a chronic combined exposure to chromium and benzene on the hypothalamic-pituitary-adrenocortical (HPA) and immune systems of male Wistar rats. Materials and methods: Eighty male Wistar rats were administered potassium dichromate and benzene with drinking water in doses equaling one maximum permissible concentration (MPC) during 135 days. The hypothalamus, pituitary gland, adrenal glands, thymus, and spleen were then studied using morphometric, histological, and electron microscopy methods. The streptavidin-biotin peroxidase method was used to determine the expression of pro-apoptotic protein p53 and anti-apoptotic protein bcl2. We also measured the body, thymus and spleen weights of animals, nucleated cell counts in the thymus, spleen, and bone marrow and evaluated the cellular composition of the spleen and bone marrow as well as spontaneous and concanavalin A-induced secretion of interferon gamma (IFN-γ), IL-4, IL-6, and IL-10 cytokines by splenocytes. Results: We established an adverse effect of the exposure on the HPA function expressed in the activation of its secretory activity, blocking the release of hypothalamic neuropeptides at the level of the neurohypophysis and leading to ultrastructural damage to the neurosecretory cells of the hypothalamus, pituitary adenocytes and adrenal cortical cells, as well as in an increase in the programmed death of thymocytes. We also observed a decrease in the thymus weight and thymocyte counts and a complex of structural and functional changes indicating the status of its accidental involution in the exposed rats. The revealed decrease in the splenocyte count in the experimental group was accompanied by an increase in the size of the white spleen pulp. An increase in the induced production of the main immunoregulatory cytokines IFN-γ and IL-4 by splenocytes was found. Conclusion: Our findings can be used to analyze impairments of the HPA and immune systems in workers with a chronic combined exposure to benzene and chromium compounds in the occupational setting.

The Impact

Sea cucumbers have been shown to have potential health benefits and are a rich source of several bioactive compounds, particularly triterpenoid saponins. However, most studies concentrate on the body wall, and little is known about the health effects of the coproducts. The objectives of this study were to determine the nutritional composition of a coproduct from the sea cucumber Cucumaria frondosa and the effects of the dietary consumption of this coproduct on cardiometabolic health in rats. Chemical, biochemical, and nutritional analyses were performed to characterize this coproduct. Forty (40) male Wistar rats were then equally divided into four groups and fed a purified control diet or a diet enriched with 0.5%, 1.5%, or 2.5% (by protein) of coproduct. After 28 days of feeding, the rats were sacrificed. Body and tissue weight, body composition, epididymal adipocyte diameter, plasma and hepatic lipids, glycemia, and insulinemia were measured at the end of the 28-day experiment. Analysis of the coproduct revealed high levels of protein, omega-3 fatty acids, minerals, and saponins. The 1.5% group had significantly smaller epididymal adipocytes vs. the control. We conclude that dietary administration of this sea cucumber coproduct at 1.5% doses decreases visceral adiposity, potentially decreasing the risk of cardiometabolic dysfunction. The coproduct’s saponin content may contribute to the observed effects, but the impact of other components cannot be ruled out.

The purpose of this work was to study changes in the level of cell-free DNA (cfDNA) in the blood of young and old rats in the normal state and with induced benign prostatic hyperplasia (BPH). Male Wistar rats were divided into 4 groups—young (3 months), old (20 months), intact, or with testosterone-induced BPH. Groups with BPH were subjected to surgical castration and administration of testosterone esters at a dose of 25 mg/kg for a total of 7 injections for 20 days. In intact animals, the level of cfDNA in old rats (2.00±0.14 ng/μl) was significantly higher than that in the young (1.02±0.30 ng/μl). The body and the prostate weights of old rats were 1.6 and 1.4 times larger than those of the young, without an increase in the prostate index (PI). The testosterone level in the blood of young rats was 1.6 times higher than that of old (6.20±0.93 nmol/l vs. 3.77±0.55 nmol/l; NS). In animals with BPH, the level of cfDNA in old rats (3.14±0.76 ng/μl) was significantly higher than that in young rats (0.80±0.14 ng/μl). The body and the prostate weights in old rats were 1.8 and 2.3 times larger, than those in young rats, with an increase in the PI. The level of testosterone in the blood of young (15.76±0.51 nmol/l) and old (16.99±1.1 nmol/l) rats was not significantly different. Morphological signs of BPH were observed in the prostate of both young and old rats. During the induction of BPH in the experiment, according to the level of cfDNA, cell death processes have not changed significantly in young rats but significantly increased in old rats. A similar trend was observed in the group of intact animals. The obtained data indicate that apoptosis processes are enhanced during the development of BPH despite the growth of tissues in the prostate itself.

Atrial Natriuretic

Magnesium is the second most abundant divalent ion in the body, but the effects of this cation on atrial natriuretic peptide (ANP) release have not been examined. The present study was conducted to determine the effect of magnesium on ANP secretion. Experiments were conducted in six groups of male Wistar rats. Each group was assigned a diet containing a different amount of magnesium. Plasma magnesium was 0.42 +/- 0.01, 0.63 +/- 0.01, 0.75 +/- 0.02, 0.97 +/- 0.03, 1.03 +/- 0.01, and 1.19 +/- 0.01 mM in groups I, II, III, IV, V, and VI, respectively. Plasma ANP concentration was significantly higher in the hypermagnesemic animals and significantly lower in the hypomagnesemic rats. A significant positive correlation was found between plasma magnesium and plasma ANP levels (y = 88 + 23 chi; r = 0.46; P less than 0.01). ANP concentration in the atria was lower in hypomagnesemic rats and higher in hypermagnesemic rats. This suggests that the low concentrations of ANP found in the plasma of hypomagnesemic animals were due to the lack of ANP in the atria. The atria from the various groups were isolated and perfused in a modified Langendorff apparatus to measure the rate of ANP secretion. Our results showed that the hypomagnesemic rats have a lower release rate as opposed to that seen in hypermagnesemic animals. A significant correlation was also seen between ANP secretion and tissue ANP concentration. The higher rate of ANP release from the heart of hypermagnesemic animals was due to the presence of more ANP, which was reduced during hypomagnesemia.(ABSTRACT TRUNCATED AT 250 WORDS)
