Hydroxyapatite Nanoparticles

Abstract Hydroxyapatite nanoparticles (HAP-NPs) are an inorganic component of natural bone and are mainly used in the tissue engineering field due to their bioactivity, osteoconductivity, biocompatibility, non-inflammatory, and non-toxicity properties. However, the current toxicity data for HAP-NPs regarding human health are limited, and only a few results from basic studies have been published. Therefore, the present study was designed to investigate the beneficial role of chitosan nanoparticles (CsNPs) and curcumin nanoparticles (CurNPs) in alleviating nephrotoxicity induced by HAP-NPs in male rats. The results showed that HAP-NPs caused a reduction in antioxidant enzymes and induced lipid peroxidation, nitric oxide production and DNA oxidation. Moreover, HAP-NP administration was associated with intense histologic changes in kidney architecture and immunoreactivity to proliferating cell nuclear antigen (PCNA). However, the presence of CsNPs and/or CurNPs along with HAP-NPs reduced the levels of oxidative stress through improving the activities of antioxidant enzymes. Also, the rats administered the nanoparticles showed a moderate improvement in glomerular damage which matched that of the control group and showed mild positive reactions to PCNA–ir in glomeruli and renal tubules in the cortical and medullary portions. These novel insights confirm that the presence of chitosan and curcumin in nanoforms has powerful biological effects with enhanced bioactivity and bioavailability phenomena compared to their microphase counterparts. Also, they were able to ameliorate the nephrotoxicity induced by HAP-NPs.

Annotation. An important measure of intensive care in patients with traumatic brain injury (TBI) is the use of pharmacotherapeutic agents with antioxidant properties. The aim of this study was to evaluate the effect of ademol compared with amantadine sulfate and 0.9% NaCl solution on the course of oxidative stress in the brain of TBI rats. The experiments were performed on 28 white male rats weighing 160-190 g. The experimental TBI model of severe severity was caused by the action of a carbon dioxide flow under pressure created using a gas balloon pneumatic gun. The therapeutic effect of ademol on model TBI was evaluated with a 2 mg/kg dose. The pseudoperated animals and control group received a 0.9% solution of NaCl and amantadine sulfate at a dose of 2 ml/kg and 5 mg/kg i/v. Data were processed using StatPlus 2009. We used the parametric criterion of t-Student, non-parametric criterion of W. White, paired criterion Ť. Wilcoxon, Fisher's angular transformation at p <0,05. In the course of the experiment, it was found that treatment of rats with TBI ademol leads to a decrease in the activity of lipid peroxidation and oxidative degradation of proteins (p<0.05) and promotes the normalization of the activity of antioxidant enzymes in cells of traumatically damaged brain (p<0.05). The use of ademol compared to amantadine sulfate and 0.9% NaCl solution was accompanied by a more significant decrease in the activity of lipid peroxidation and oxidative degradation of proteins and an improvement in the level of antioxidant enzymes in damaged brain of animals with TBI (p<0.05).

Aim: The present study aimed to elucidate the effects of tramadol on the testicular functions of adult male rats due to the chronic usage of tramadol and the effect of its withdrawal. Method: Adult male albino rats were classified into the following 3 groups: (I) a control administered with normal saline and (II) tramadol-treated rats (40 mg/kg b.w. orally) for 21 successive days; and (III) like the rats in the second group but kept for 4 weeks after the last tramadol dose to study the effect of tramadol withdrawal. At the end of the experimental period, blood was collected and specimens from testis were taken for histopathological, biochemical, and molecular studies. A reverse transcription-polymerized chain reaction after RNA extraction from specimens was detected for the anti-apoptotic and pro-apoptotic genes in testicular tissues. Also, malondialdehyde (MDA) was measured in tissues homogenate and antioxidant enzymes activities were evaluated. Results: The results of this study demonstrated histological changes in testicular tissues in groups II and III compared to the control group, accompanied with increased apoptotic index and proved by increased B-cell lymphoma-2 (Bcl-2) associated-X-protein and caspase-3 expression, whereas anti-apoptotic Bcl-2 markedly decreased. Moreover, in tramadol-abused and -withdrawal groups, the MDA level increased, while the antioxidant enzymes activity decreased and revealed oxidative stress, indicating that tramadol is harmful at the cellular level and can induce apoptotic changes in testicular tissues. The withdrawal effect showed signs of improvement, but it did not return to normal levels. Conclusions: It could be concluded that the administration of tramadol causes abnormalities on testicular tissues associated with oxidative stress, which confirmed the risk of increased oxidative stress on testicular tissues due to tramadol abuse.

Long Term Effects

Oxidative stress is a common culprit of several conditions associated with male fertility. High levels of reactive oxygen species (ROS) promote impairment of sperm quality mainly by decreasing motility and increasing the levels of DNA oxidation. Oxidative stress is a common feature of environmental pollutants, chemotherapy and other chemicals, smoke, toxins, radiation, and diseases that can have negative effects on fertility. Peroxiredoxins (PRDXs) are antioxidant enzymes associated with the protection of mammalian spermatozoa against oxidative stress and the regulation of sperm viability and capacitation. In the present study, we aimed to determine the long-term effects of oxidative stress in the testis, epididymis and spermatozoa using the rat model. Adult male rats were treated with tert-butyl hydroperoxide (t-BHP) or saline (control group), and reproductive organs and spermatozoa were collected at 3, 6, and 9 weeks after the end of treatment. We determined sperm DNA oxidation and motility, and levels of lipid peroxidation and protein expression of antioxidant enzymes in epididymis and testis. We observed that cauda epididymal spermatozoa displayed low motility and high DNA oxidation levels at all times. Lipid peroxidation was higher in caput and cauda epididymis of treated rats at 3 and 6 weeks but was similar to control levels at 9 weeks. PRDX6 was upregulated in the epididymis due to t-BHP; PRDX1 and catalase, although not significant, followed similar trend of increase. Testis of treated rats did not show signs of oxidative stress nor upregulation of antioxidant enzymes. We concluded that t-BHP-dependent oxidative stress promoted long-term changes in the epididymis and maturing spermatozoa that result in the impairment of sperm quality.

Oxidative stress is a physiological imbalance between the production of reactive oxygen species (ROS) and the body’s ability to detoxify these products. Oxidative stress induced by ionizing radiation is one of the late biological effects of radiation. The aim of this study was to assess the protective role of Angelica archangelica and Ginkgo biloba extracts, which are commonly used as antioxidants in counteracting effects related to functional and non-functional hemoglobin derivative concentrations, as well as the rate of hemoglobin autoxidation before exposing rabbits to ionizing radiation. The experimental design included four groups of rabbits: a control group that did not receive gallium or antioxidants; Group 1, which received 68Ga isotope as a source of ionizing radiation with no prior treatment; Groups 2 and 3, which received A. archangelica and G. biloba root powder water extracts, respectively, for seven days prior to irradiation; and Group 4, which received a combined dose of both antioxidants, A. archangelica and G. biloba, prior to irradiation, with the same dose, time, and duration as used in Groups 2 and 3. The results demonstrate that both antioxidants had the ability to counteract oxidative stress induced by ionizing radiation, as well as to reduce the hemoglobin autoxidation rate. A synergistic effect was revealed when using a combined dose of both antioxidants at the same concentrations, times, and durations. A lower rate of free radical formation was also recorded, reflected by a reduction in superoxide dismutase (SOD) and glutathione peroxidase activity. The data here presented support the radioprotective role of both investigated antioxidants.

Introdution: Diabetes is the most common endocrine disorder characterized by hyperglycemia. Increasing the oxidative stress and changing the amount of antioxidants play important roles in pathogenesis of diabetes. Nowadays to control diabetes and its complications, the use of herbal drugs is considered widely. In this study, we investigated the effect of oleuropein on antioxidant enzymes activity of heart tissue in Streptozotocin induced diabetic male rats. Methods: In this study, 30 adult male Wistar rats with a weight range of 190±30 gr were randomly divided into 3 groups(n=10 in each group): 1) control group or intact rats, 2) diabetic rats, and 3) treatment group, which received 60 mg/kg oleuropein for 30 days by gastric gavage. Diabetes was induced by injection of streptozotocin (60 mg/kg) intraperitoneally. At the end of the treatment, serum concentrations of blood glucose and heart tissue antioxidant enzymes activity were determined. The obtained data were analyzed using  SPSS Inc., Chicago, IL; Version 18, statistical method of one way variance analysis and post hoc-Duncan test . Results: The results showed that serum concentration of glucose decrease significantly in treatment group compared with the diabetic group (p=0.000). Also, TAC, SOD and GPX activity increased significantly in the treatment group compared with the diabetic group (p=0.000). Conclusion: This study showed that oleuropein can prevent blood glucose increasing and reinforce antioxidant system of cardiac tissue in diabetic rats.

Quercetin (Qu) is an important polyphenolic flavonoid which exhibits tremendous antioxidant, anti-inflammatory and other health promoting effects. The aim of the current study was to explore the therapeutic role of Qu on benzo(a)pyrene [B(a)P]-induced lung injury in rats. B(a)P was given to the rats at dose of 50 mg/kg b.w. for continues 8 weeks through oral gavage. The rats were treated with Qu at dose of 50 mg/kg b.w prior 30 min before the oral administration of B(a)P. The effects of Qu were studied by measuring the level of lactate dehydrogenase (LDH), anti-oxidant enzymes, lipid peroxidation, inflammatory cytokines, lung tissues architecture and expression of cyclooxygenase-2 (COX-2). The level of pro‑inflammatory cytokines such as IL-1β (27.30 vs. 22.80 pg/mL), IL-6 (90.64 vs. 55.49 pg/mL) and TNF-α (56.64 vs. 40.49 pg/mL) increased significantly and antioxidant enzymes decreased significantly in benzopyrene-induced lung injury in comparison to the control group. The treatment with Qu potentially reversed the effects of B(a)P to a great extent, as it led to the enhancement of antioxidant enzymes and decreased proinflammatory cytokines level. A significant surge of VEGF level was noticed in the B(a)P group as compared to the control group, while the Qu treatment groups exhibited less angiogenesis as lower level of VEGF levels, compared with the B(a)P treatment group. The Qu treatment significantly decreased the degrees of histopathological changes and collagen deposition in B(a)P-induced lung injury. The B(a)P-treated group showed higher cytoplasmic expression of COX-2 protein, which significantly decreased in the Qu treatment group. These outcomes recommend an effective role of Qu in the protection of lung injury against B(a)P through the regulation of the inflammatory factors, oxidative stress and the maintenance lung tissue architecture.

Background: Nerium oleander (NO) distillate is used to either protect heart cells against oxidative stress or reduce the risk of cardiovascular disease by regulating the production of reactive oxygen species. Hypoxia-inducible factors (HIFs) regulate cellular antioxidant defense mechanisms under hypoxic conditions in which heart cells survive; however, the key responsible mechanism of NO distillate for cardioprotection remains elusive. The objective of this study was to evaluate the effects on heart tissue at different time intervals after administering NO distillateintraperitoneally (IP) while considering the transcriptional regulation of HIFs and representative antioxidant enzymes.Materials, Methods &amp; Results: The NO plant was chopped, and distillated water was added. The mixture was distilled, and the distillate separated and collected into tubes, after which it was lyophilized to obtain dry material. Twenty male Wistar albino rats (2-3 month-old, 250-300 geach) were used in the study. The rats were randomly divided into four groups. The control group (n = 5) received IP injections of saline; the remaining 15 rats received IP injections of a single dose of 7.5 mL NO distillate. The NO distillate injected rats were divided into three groupsaccording to the time from injection to harvest the heart tissue samples. The tissues were collected at 0 h (control; n = 5), 2 h (group 2; n = 5), 4 h (group 3; n = 5), and 8 h (group 4; n = 5) after injection and under general anesthesia (60 mg/kg ketamine, IP + 10 mg/kg xylazine, IP).Quantitative polymerase chain reaction (qPCR) was used to assess the expression profiles of the genes of interest in the heart tissues. Hypoxanthine phosphoribosyltransferase was used as the reference gene. The expression of manganese superoxide dismutase (MnSOD) mRNA was in a steady state level between the control group and group 2 (P &gt; 0.05); however, it significantly increased in group 3 and 4 compared with that in the control (P &lt; 0.05). Expression of catalase (CAT) mRNA was significantly higher in group 2 than in the control group (P &lt; 0.05) although it was lower in group 3 and 4 than in group 2 (P &lt; 0.05); however, it appeared to be similar among the control group, group 3, and group 4 (P &gt; 0.05). Copper (Cu) SOD mRNA was equallyexpressed in both the control group and group 2 (P &gt; 0.05) but was lower in group 3 and 4 than in group 2 (P &lt; 0.05). Expressions of HIF1A, HIF2A, and HIF3A mRNA were detected in the rat heart tissues in the control and 2, 4, and 8 h after administration of NO distillate. Expression ofHIF1A mRNA was in a steady state and did not differ among groups 2, 3, and 4 (P &gt; 0.05). Similarly, the expression of HIF2A mRNA did not change between the control group and group 2 (P &gt; 0.05); however, it was higher in group 3 than in the control (P &lt; 0.05) and tended to behigher in group 3 than in group 2 (P = 0.063). HIF3A mRNA expression did not change significantly in the heart tissue of any of the groups (P &gt; 0.05).Discussion: The present study using rats determined that MnSOD, CAT, CuSOD, HIF1A, HIF2A, and HIF3A mRNA are expressed in the heart tissues after administration of NO distillate. The increased expression of HIF2A mRNA after 4 h in accordance with a rise in CAT mRNA after 2 h, and MnSOD mRNA after 4 and 8 h might confirm the role of HIF2A mRNA in oxidative stress defense by regulating antioxidant enzymes; consequently, this study may expand our understanding of uses of NO distillate with respect to molecular pathways.

Ginseng Extract

This study investigates the modulating effect of ginseng against testicular toxicity, oxidative stress and changes in some biochemical parameters induced by doxorubicin. Twenty male rats were divided into four groups. The 1st group received distilled water orally (control group), The 2nd group received doxorubicin (5 mg/kg b.wt. intrapertenoineal) once a week for eight weeks, The 3rd group received ginseng extract (200 mg/kg b.wt.) daily for eight weeks and the 4th group received doxorubicin with ginseng extract by the same doses as in the 2nd and the 3rd groups respectively. At the end of the 8th week, blood and semen samples were taken for biochemical and semen analysis, respectively. The doxorubicin treated group had significantly higher serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), Creatine kinase (CK) and lactate dehydrogenase (LDH) along with lower levels of total protein, albumin and globulin. In addition, a significant decrease in antioxidant enzymes (SOD, CAT, GSHPx), and glutathione (GSH) associated with higher level of malondialdehyde (MDA) were observed. At the same time, the group that took doxorubicin with ginseng did not differ from control group in terms of these parameters. Male fertility study showed changes in testosterone and semen analysis in both groups treated with doxorubicin, while the group that took doxorubicin with ginseng showed an improvement towards control levels of these parameters. Thus ginseng supplement can reduce the negative effects of doxorubicin- induce.

Abstract Background Few studies have examined nano-sized plastic particulates (NPs) exposure in relation to oxidative stress and biochemical responses in rodents, commonly used for toxicity evaluations on which to base risk assessment for humans.Methods Here we explored possible oxidative stress and biochemical responses of five weeks oral exposure to polystyrene (PS) nanoparticles (1, 3, 6 and 10 mg/kg body weight per day) in male rats. We used variance analysis and variance explained statistic eta-squared (𝜂2) to estimate the strength of relationships worked out. The whole body scanning further provided insight into the bio-distribution of nanoplastics upon oral exposure.Results Results demonstrated the accumulation of PS-NPs through whole body and also a dose-dependent increase in the production of reactive oxygen species (ROS). Significant alterations in antioxidant responses including serum levels of catalase, superoxide dismutase (SOD), and total glutathione content were noticed, pointing towards a perturbation of redox state induced by the exposure conditions. Acetylcholinesterase level in highest dose group was about 40 percent lower than those in control group. Biochemical parameters viz. glucose, cortisol, lipase, lactate, lactate dehydrogenase (LDH), alkaline phosphatase, gamma-glutamyl transpeptidase (GGT), triglycerides, and urea showed a significant increase, while total protein, albumin and globulin levels showed an appreciable decline.Conclusion The pattern of associations noticed with AChE activity and biochemical responses in our study suggests the possibility that a neurobehavioral effect or dysfunctions in energy metabolism, or both, may be the potential mode of action, possibly through stress response as well as liver function. Perturbations of creatinine and uric acid levels are indeed plausible biological explanations for the association with kidney dysfunction. Although we provided a new scientific clue for exploring the biological effects of plastics nanoparticles, the results warrant additional research with a larger sample size. The suggested potential mechanisms also remains to be investigated.
