Chronic Immobilization Stress

Objective. The aim of this study was to investigate protective effects of resveratrol, a strong antioxidant, against possible negative effects of chronic immobilization stress on testes of male rats histochemically, immunohistochemically, ultrastructurally, and biochemically. Material and Methods. Male Wistar rats were divided into 4 groups (n=7). Group I, control group (C), was not exposed to stress. Group II, stress group (S), was exposed to chronic immobilization stress. In Group III, low dose resveratrol + stress group (LRS), rats were given 10 mg/kg/day resveratrol just before the stress application. In Group IV, high dose resveratrol + stress group (HRS), rats were given 20 mg/kg/day resveratrol just before the stress application. For chronic immobilization stress application animals were put in the plastic tubes (6 cm in diameter, 15 cm in length) during 32 days for 6 hours. All animals were sacrificed 18 hours after the last stress application. Results. Histochemical and ultrastructural investigations showed that in stress group there was germ cell deprivation in seminiferous tubules and increase of connective tissue on interstitial area. No significant changes were seen in low and high dose resveratrol groups. After immunohistochemical investigations, TUNEL (+) and Active Caspase-3 (+) cells were increased in seminiferous tubules of stress group compared with those control group, but they were decreased in low and high dose resveratrol groups. According to biochemically results, MDA, GSH, and testosterone levels in stress group showed no significant difference when compared with those of the other groups. Conclusion. The chronic immobilization stress increases oxidative stress and apoptosis and causes histological tissue damages; resveratrol can minimize the histological damage in testes significantly.

Chronic Immobilization Stress

Abstract. Alterations of essential elements in the brain are associated with the pathophysiology of many neuropsychiatric disorders. It is known that chronic/overwhelming stress may cause some anxiety and/or depression. We aimed to investigate the effects of two different chronic immobilization stress protocols on anxiety-related behaviors and brain minerals. Adult male Wistar rats were divided into 3 groups as follows ( n = 10/group): control, immobilization stress-1 (45 minutes daily for 7-day) and immobilization stress-2 (45 minutes twice a day for 7-day). Stress-related behaviors were evaluated by open field test and forced swimming test. In the immobilization stress-1 and immobilization stress-2 groups, percentage of time spent in the central area (6.38 ± 0.41% and 6.28 ± 1.03% respectively, p < 0.05) and rearing frequency (2.75 ± 0.41 and 3.85 ± 0.46, p < 0.01 and p < 0.05, respectively) were lower, latency to center area (49.11 ± 5.87 s and 44.92 ± 8.04 s, p < 0.01 and p < 0.01, respectively), were higher than the control group (8.65 ± 0.49%, 5.37 ± 0.44 and 15.3 ± 3.32 s, respectively). In the immobilization stress-1 group, zinc (12.65 ± 0.1 ppm, p < 0.001), magnesium (170.4 ± 1.7 ppm, p < 0.005) and phosphate (2.76 ± 0.1 ppm, p < 0.05) levels were lower than the control group (13.87 ± 0.16 ppm, 179.31 ± 1.87 ppm and 3.11 ± 0.06 ppm, respectively). In the immobilization stress-2 group, magnesium (171.56 ± 1.87 ppm, p < 0.05), phosphate (2.44 ± 0.07 ppm, p < 0.001) levels were lower, and manganese (373.68 ± 5.76 ppb, p < 0.001) and copper (2.79 ± 0.15 ppm, p < 0.05) levels were higher than the control group (179.31 ± 1.87 ppm, 3.11 ± 0.06 ppm, 327.25 ± 8.35 ppb and 2.45 ± 0.05 ppm, respectively). Our results indicated that 7-day chronic immobilization stress increased anxiety-related behaviors in both stress groups. Zinc, magnesium, phosphate, copper and manganese levels were affected in the brain.

This study investigated the reproductive toxicity of methylmercury (MeHg) and Aroclor (Sigma-Aldrich), alone or in combination, following exposure of prepubertal male rats considering the chromatoid body (CB) as a potential target. The CB is an important molecular regulator of mammalian spermatogenesis, primarily during spermatid cytodifferentiation. Male Wistar rats were exposed to MeHg and/or Aroclor , according the following experimental design: control group, which was administered in corn oil (vehicle) only; MeHg-treated group, which was administered 0.5mg kg−1 day−1 MeHg; Aroclor-treated group, which was administered 1mg kg−1 day−1 Aroclor; Mix-LD, group which was administered a low-dose mixture of MeHg (0.05mg kg−1 day−1) and Aroclor (0.1mg kg−1 day−1); and Mix-HD group, which was administered a high-dose mixture of MeHg (0.5mg kg−1 day−1) and Aroclor (1.0mg kg−1 day−1). MeHg was diluted in distilled water and Aroclor was made up in corn oil (volume 1mL kg−1). Rats were administered the different treatments from PND23 to PND53 by gavage, . The morphophysiology of CBs was analysed, together with aspects of steroid hormones status and regulation, just after the last treatment on PND53. In addition, the long-term effects on sperm parameters were assessed in adult animals. MeHg exposure increased mouse VASA homologue (MVH) protein levels in seminiferous tubules, possibly affecting the epigenetic status of germ cells. Aroclor produced morphological changes to CB assembly, which may explain the observed morphological defects to the sperm flagellum and the consequent decrease in sperm motility. There were no clear additive or synergistic effects between MeHg and Aroclor when administered in combination. In conclusion, this study demonstrates that MeHg and Aroclor have independent deleterious effects on the developing testis, causing molecular and morphological changes in CBs. To the best of our knowledge, this is the first study to show that CBs are targets for toxic agents.

Doxorubicin (DOX) is one of the most potent and widely used chemotherapeutic agents to treat several malignancies. However, the clinical use of DOX is seriously restricted due to its acute and chronic cardiotoxic side effects This study investigated the protective effect of (Ajwa) date aqueous extract (AJDAE) against doxorubicin-induced cardiotoxicity in rats. Sixty Wister albino male rats (150-200 gms.) were comprised in our study and divided into six equal groups: group I (untreated control), group II, group III, rats were orally received AJDAE (0.75 & 1.5 gm/ kg.bw) respectively, for 4 weeks, rats of groups IV, V and VI were intraperitoneally injected with one dose of doxorubicin (5 mg/kg.bw) at the end of the 4th week of the study to induce cardiotoxicity, rats of groups V & VI were orally received AJDAE (0.75 & 1.5 gm/ kg.bw) respectively. Cardiac enzymes, lipid profile, SOD, GR, GST, GPx, CAT and MDA in rats’ hearts homogenate, urinary 8OHdG as well as DNA integrity and histopathological changes were investigated in all studied rats.Oral administration of AJDAE (0.75 & 1.5 gm/ kg.bw) attenuated the cardiotoxicity of DOX, improved the cardiac enzymes, lipid profile, reduced the urinary 8OHdG and prohibited the depletion of endogenous antioxidants and suppressed lipid peroxidation (MDA). Moreover, AJDAE enhanced DNA integrity. Histological findings showed that AJDAE (0.75 & 1.5 gm/ kg.bw) administration reduced cardiomyocytes alterations, congestion, edema and the intense cellular stress exerted on myocardial fibers as well as restored the cardiomyocytes architecture. Our data showed that AJDAE obviously resulted in protective effects against DOX-induced cardiotoxicity in rat’s heart. It can be concluded that Ajwa date offers a considerable protection against DOX-induced cardiotoxicity.

Objective: Protective effects of Tribulus terrestris (TT) and vitamin C were studied against permethrin induced changes in the histoarchitecture of goat testis.Methods: Hydroalcoholic extract of the fruits of Tribulus terrestris was prepared by maceration method and the extractive value was calculated. Fresh stock solution of permethrin (1mg/ml) in dimethyl sulphoxide and Tribulus terrestris (1mg/ml) in distilled water were prepared. Testicular tissues were cultured in TCM-199 nutrition media at 39℃ with 95% humidity and 5% CO₂ in the CO₂ incubator. Cultured testicular tissue was grouped as control having only the nutritive media, experimental group I(EI) received two doses of permethrin (100µg/ml and 200µg/ml), experimental group II(EII) was administered doses of permethrin along with vitamin C(0.1µM/ml) and experimental group III(EIII) was supplemented with doses of permethrin along with Tribulus terrestris (100µg/ml). All the groups were tested for 4 hr. and 8hr. for histoarcitectural studies.Results: Histological alterations were observed such as distorted shape of seminiferous tubules, decreased luminal and interstitial space, reduction in the population of spermatocytes, spermatozoa and spermatids in treated (E1) group as compared to control group. Maximum damage was detected at a higher dose of permethrin (200µg/ml) for 8h in contrast to lower doses (100 4h and 8h). Thus, it is concluded that permethrin has both dose and time-dependent effects. Protective groups (E2 and E3) imparted ameliorative effects by reestablishing shape of seminiferous tubules, decreasing luminal and interstitial space, increased population of spermatocyte, spermatozoa, and spermatids as compared with treated groups (E1)Conclusion: It has been reported that permethrin affects male fertility by inducing detrimental changes in the structure and function of seminiferous tubules. Both vitamin C and TT have the ability to mitigate the effect of pesticide. TT shows aphrodisiac activity against permethrin induced alterations in goat testis.

Cottonseed oil is an extract from the seeds of cotton plant, that is rich in protein, carbohydrate and fiber.          The objective of the research was to study the effect of cottonseed oil on the histology of the testis.          Materials and methods. Twelve adult male Wistar rats weighing 200 – 250g, were randomly sorted into four groups (I - IV), each containing three animals. Cottonseed oil was administered orally to the experimental animals by means of an orogastric tube. The rats in Group I (the control group) received standard rat pellet and oral normal saline ad libitum only. The animals in Groups II, III, and IV received 0.2 ml, 0.6 ml and 1.0 ml of cotton seed oil per body weight respectively. On the 21st day, the animals were sacrificed by cervical dislocation. The testes were excised and, then, fixed with appropriate fixatives for routine tissue processing.          Results. The results revealed an increase in the luminal diameter of seminiferous tubules, a decrease in the Leydig cell population, the disorientation of spermatogenic series and their detachment from the germinal epithelium.          Conclusions. The present study demonstrated that oral administration of cottonseed oil to male rats displayed a deleterious effect on their testis by disrupting spermatogenesis and the histological architecture of the testis.

Background: Betel nut (Areca catechu L) are traditional beverages in Jambi. Betel nut high dose has a cytotoxic effect on testis and other organs—limited data about the effect of betel nut as male antifertility.Purposes:  This study aimed to determine the effect of infertility on betel nut use at a dose of 50 mg/kg body weight (BW) in male rats.   Methods: Ten male Sprague Dawney rats that had passed the fertility test, aged 2-3 months and weighing 150-200 grams ware used in this study. The rat was grouped into two groups randomly. Group 1, as the negative control, were received aqua dest, and group 2 was treated by betel nut with dose 50 mg/kg BW for 35 days. When terminated, testis weight weighed using micro scales. Blood collected for measuring testosterone levels. Histopathology assessment of testis used Hematoxylin Eosin Staining and sperm counting from cauda epididymis.Results: The weight of testis in the group received betel nut was lower than the control group. The histopathology of testis showed shrunk, reduced the diameter of seminiferous tubules, and like cytolytic lesions in the germinal layer—the total sperm number and progressive sperms also lower than the control group (p<0.05). There was no abnormality in Leydig cell and interstitium tissue.  Male rats after treatment could not impregnate the female rats.Conclusion: Betel nut at dose 50 mg/kg BW have antifertility activity in male rats.

Melamine and its analogues are illegally added to raise the apparent protein content in foods. The elevated concentrations of these compounds cause adverse effects in humans and animals. In this contribution, the protective effects of the synthesized starch-stabilized selenium nanoparticles (Se-NPs@starch) on melamine-induced hepato-renal toxicity have been systematically investigated. The Se-NPs@starch were characterized by X-ray photoelectron spectroscopy (XPS) analysis, energy dispersive spectroscopy (EDS) mapping analysis, TEM, and FT-IR. Starch plays a crucial role in the stabilization and dispersion of Se NPs, as noticed from the TEM and EDS investigations. Furthermore, the atomic ratio of Se distribution over the starch surface is approximately 1.67%. The current study was conducted on four groups of adult male rats, and the oral daily treatments for 28 days were as follows: group I served as control, group II received Se-NPs@starch, group III was exposed to melamine, while group IV was treated with melamine and Se-NPs@starch. The results reveal a significant alteration in the histoarchitecture of both hepatic and renal tissues induced by melamine. Furthermore, elevated liver and kidney function markers, high malondialdehyde, and increased expression levels of apoptosis-related genes besides a reduction in GSH and expression levels of antioxidant genes were observed in the melamine-exposed group. Interestingly, the administration of the Se-NPs@starch resulted in remarkable protection of rats against melamine-induced toxicity through increasing the antioxidant capacity and inhibiting oxidative damage. Collectively, this study provides affordable starch-stabilized Se-NPs with potent biological activity, making them auspicious candidates for prospective biomedical applications.

We undertook this study with the aim of investigating the detoxification of an extreme toxic metal mercury chloride by the Calotropis procera plant taken from the Algerian Sahara. We studied the protective effects of the plant Calotropis procera against renal toxicity and Mercury chloride-induced hepatic. Ten male and female albino rats Wistar were divided into four equal groups. Group (I) served as a healthy control group, group (II) were intra-peritoneal administered with 10 ml of Calotropis procera, group (III) were intra-peritoneal administrated with both 10 ml of the plant Calotropis procera and 0.2 mg of mercuric chloride (HgCl2) and group (IV) were intraperitoneal administrated with both 0.2 mg of mercuric chlorid (HgCl2) and 10 ml of the plant Calotropis. All groups were treated for 20 days. Mercury chloride causes a slight increase in glomerular cellularitis in the kidneys of male and female rats. Treatment with Calotropis procera had significantly improving protective effects of kidney of female rats from toxicity of mercuric chloride. Calotropis procera causes a thyroid-like appearance in the glomeruli of the male kidneys to hide the lesions of mercury chloride. Our results have shown that the plant Calotropis procera completely protects the liver of female rats against the toxicity of mercury chloride. In the liver of male rats, mercury chloride causes macro-vacuolar steatosis. Treatment with Calotrpois procera hid the hepatic steatosis of male rats and centralized them in the center under the aspect of peri-centro-lobular medio-vacuolar steatosis. Mercuric chloride caused a decrease in the secretion of the hormone ACTH in the group of male and female rats. Treatment with Calotropis procera caused increased ACTH levels in female rats and did not cause ACTH changes in male rats. Our results demonstrate from hormone analyzes of the hormone ACTH that female rats are resistant more than male rats via the toxicity of mercury chloride.

Abstract Background To investigate the protective effect of vitamin E on mice adrenal glands in immobilization stress and to examine post-stress behavioral changes. Twenty-eight male, 10-week-old, BALB/C mice weighing 30 grams were divided into four groups. Mice were placed in a cage where no movement was allowed 6 hours/day for 7 days for immobilization stress. 0.1ml saline was administered to the control group and the stress group for 7 days, whereas 30 mg/kg/day vitamin E was administered orogastrically 1 hour before immobilization stress in the vitamin E and stress + vitamin E group. At the end of the 7th day, all animals were subjected to open field, elevated-plus maze (anxiety) and forced swimming (depression) tests. Left adrenal glands were dissected for routine paraffin tissue protocol. Sections were stained with hematoxylin-eosin and Azan. Malonaldehyde (MDA) levels were also measured in the adrenal tissues. Results Anxiety symptoms were not significant between groups (0.582). Depression level (p = 0.024) and MDA values (p = 0.01) were the highest in the stress group, which was significantly higher than that of the vitamin E group. In the hematoxylin-eosin sections of the stress group, cortical atrophy, medullary hypertrophy, dilated capillaries, and hemorrhage were observed. Azan staining revealed a thinned capsule, cortical fibrosis, and intense fibrosis in the stress group. Histological structure was protected in the stress + vitamin E group, but dilatation and interstitial fibrosis were also detected. Conclusion Immobilization stress may cause some psychopharmacological, morphometric, and histopathologic changes in mouse adrenal glands, and vitamin E may largely protect the gland from these effects.

Chronic Immobilization Stress

Immobilization induces oxidative damage to the brain. Ilex paraguariensis extracts (Mate) and their major natural compound, chlorogenic acid (CGA), exert protective effects against reactive oxygen species formation. Here, the effects of Mate and CGA on oxidative damage induced by chronic immobilization stress (CIS) in the cortex, hippocampus, and striatum were investigated. For CIS, animals were immobilized for 6 h every day for 21 consecutive days. Rats received Mate or CGA by intragastric gavage 30 min before every restraint session. Endpoints of oxidative stress (levels of lipid peroxidation, protein carbonylation, and reduced (GSH) and oxidized (GSSG) forms of glutathione) were evaluated following CIS. While CIS increased oxidized lipid and carbonyl levels in all brain regions, CGA (and Mate to a lesser extent) attenuated lipid and protein oxidation as compared with control groups. GSH/GSSG balance showed a tendency to increase in all regions in response to stress and antioxidants. Taken together, our results support a protective role of dietary antioxidants against the neuronal consequences of stress.
