Scrotal hyperthermia leads to oxidative stress and apoptosis in spermatogenic cells, which subsequently causes male infertility. In this study, we examined the effects ofβ-carotene and/or curcumin on heat-stress- (HS-) induced testicular injuries in mice. ICR male mice (8 weeks old) were consecutively treated withβ-carotene (10 mg/kg) and/or curcumin (20 mg/kg) orally once a day for 14 days and then subjected to single exposure with scrotal HS at 43°C for 15 min on day 7. HS induced a significant reduction in testicular weight, appearance of multinucleated giant cells, and desquamation of germ cells in destructive seminiferous tubules, as well as degenerative Leydig cells. Moreover, HS reduced the superoxide dismutase (SOD) activity and mRNA levels of mitochondrial SOD, phospholipid hydroperoxide glutathione peroxidase, B-cell lymphoma-extra-large, and 3β-hydroxysteroid dehydrogenase, with increases in lipid peroxidation levels and mRNA levels of BCL2-associated X protein and caspase-3 relative to those of the control group. However, these changes were significantly recovered by combined treatment withβ-carotene and curcumin after HS. These findings indicate that the combined treatment withβ-carotene and curcumin might be a valuable protective agent to ameliorate hyperthermic spermatogenic disorders via its potent antioxidative, antiapoptotic, and androgen synthetic effects.

Cadmium (Cd) has been recognised as one of the most important environmental and industrial pollutants, and up-to-date investigations have shown that one of the mechanisms of its toxicity is associated with the induction of oxidative stress. The aim of this study was to determine the connection between acute oral and intraperitoneal exposure to Cd and parameters indicative of oxidative stress in the plasma of rats, as well as to examine the potential protective effect of magnesium (Mg) in conditions of acute oral and intraperitoneal Cd poisoning. The experiment was performed on male albino Wistar rats (n=40) randomly divided into control group, Cdor group that received 30 mg kg-1 b.w. Cd by oral gavage, Cd+Mgor group that orally received 50 mg kg-1 b.w. Mg one hour before oral Cd, Cdip group that received 1.5 mg kg-1 b.w. Cd intraperitoneally, and Cd+Mgip group that intraperitoneally received 3 mg kg-1 b.w. Mg 10 min before intraperitoneal Cd. The animals were sacrifi ced 24 h after treatment and the following parameters were measured: superoxidedismutase activity, superoxide anion, total oxidative status, advanced oxidation protein products, and malondialdehyde. All parameters of oxidative stress in rat plasma were negatively affected by Cd treatment with more pronounced negative effects after intraperitoneal treatment, with the exception of superoxide dismutase (SOD) activity. Although both oral and intraperitoneal Mg pretreatment had protective effects, more pronounced benefi cial effects were observed after oral administration, since it managed to completely prevent Cd-induced changes in the investigated parameters. The observed results support the use of Mg as potential protective agent against toxic effects caused by Cd.

Usage of electronic gadgets like microwave oven is increasing day by day that heats the food by exposing it to electromagnetic radiations which has many hazardous effects on human health including fertility. Aim: To find the effects of microwave oven exposed diet on basal lamina of seminiferous tubules of mice alongwith protective effects of Mentha piperita and melatonin on the same tissue. Study Design: Randomized control trial. Methodology: Adult male mice (n=32) were divided into four groups. Control group (G1) received standard pellets prepared for mice. Second group (G2) was given mice pellets exposed to microwave oven. Third group (G3) received Mentha Piperita leaf extract along with mice pellets exposed to microwave oven and the fourth group (G4) received oral melatonin along with pellets exposed to microwave oven. Later their testicular tissue was removed for histological examination while basal lamina disruption was assessed by scoring. Data analyzed by SPSS 22.0v. Results: In group G2, there was slight disruption in the basal lamina in 75% of the cases while in experimental group G3, there was slight disruption of basal lamina only in 12.5% of the cases. However, in group G4, only 25% specimen had slight disruption of basal lamina Conclusion: It was concluded that microwave oven exposed diet produced severe disruption of basal lamina in group G2 that decreased in Mentha piperita and melatonin treated groups. However, Mentha piperita treated group produced better results than melatonin treated group. Keywords: Mice, Testis, Basal Lamina, Mentha piperita and Melatonin

Introduction. Nowadays, it has been shown that one of the possible ways to increase the effectiveness of the treatment of malignant tumors is the use of combined treatment methods. Aim. To study the intensity of lipid peroxidation (LPO) and the activity of superoxide dismutase (SOD) in hyperthermia against the background of bee venom in the blood of tumor-bearing rats. Materials and methods. The experimental animals were divided into 5 groups: 1st — intact; 2nd — control (tumor-bearing animals (PS-1 tumor strain) with intraperitoneal (IP) administration of saline solution); 3rd, 4th and 5th groups — tumor-bearing animals with IP administration of 0.5 ml of bee venom against the background of hyperthermia 42, 43 and 44°C respectively. The content of diene and triene conjugates, Schiff bases (SB) and SOD activity in the blood of animals was determined. Results. From the 1st day after the end of the experiment, a statistically significant decrease in triene conjugates was recorded in all experimental groups compared to the control group. SB decreased on the 1st–7th day after the end of the experiment with the action of hyperthermia 42°C and bee venom, on the 7th–28th day — with the action of hyperthermia 43°C and bee venom, and on the 28th day — with the action of bee venom and hyperthermia 44°C, which was accompanied by an increase in SOD activity from the 7th day in all experimental groups compared to the control group. Conclusion. Hyperthermia in combination with the action of bee venom causes a decrease in lipid peroxidation products and an increase in antioxidant activity in the blood of tumor-bearing rats. The most effective action, in our opinion, is the use of bee venom against the background of hyperthermia of 43°C, at which a prolonged effect is recorded both with respect to a decrease in the concentration of SB and an increase in the activity of SOD.

ABSTRACT: This study aimed to assess the possible occurrence of reproductive changes in male goats associated with ingestion of Cenostigma pyramidale hay. Sixteen animals divided into two experimental groups, G1 and G2 (control group) were used. Animals in G1 received 2% of forage, based on live weight (LW), composed of 100% of C. pyramidale, and animals in G2 received 2% of Panicum maximum “Massai’ grass hay, based on LW. Both groups received 1% of concentrated feed supplementation based on LW, along with mineralized salt and water ad libitum. The goats were subjected to weighing, testicular biometry, and semen and blood collection every 30 days. After 120 days, the animals were castrated and their testes were collected. Testicular measurements were performed and fragments were collected for histological processing to determine the gonadosomatic index (GSI), diameter of the seminiferous tubules, height of the germinal epithelium (HGE), volumetric proportion and volume of the testicular parenchyma components, total length of the seminiferous tubules, length of the seminiferous tubules per gram of testis, and leydigosomatic and tubulosomatic indexes. The data were evaluated for normality using the Student’s t-test. Data with normal distribution were assessed using analysis of variance (ANOVA) and the non-parametric data were evaluated using the Kruskal-Wallis test, both at 5% probability. Statistically significant differences (p<0.05) were observed for GSI (G1=0.48 ±0.08 and G2=0.34 ±0.09) and HGE (G1=52.95 ±2.99 and G2=.47.63 ±2.67) between treatments. Consumption of C. pyramidale hay increased LW and, consequently, testicular weight, contributing to high GSI. In conclusion, ingestion of C. pyramidale has no toxic effect on the testicular, seminal and histological parameters of goat testis. Due to its nutritional characteristics, consumption of this plant improves animal body development. Because C. pyramidale is adapted to semi-arid regions, it can be an alternative source of feed for goats during periods of shortage.

Doxorubicin (DOX) is effective chemotherapy in several malignancies, but large-scale toxicities limit its clinical usefulness. Propolis has been reported to exhibit a broad spectrum of biological activities. We aim to assess the protective efficacy of propolis against DOX-induced multi-toxicity in female rats. Forty female rats were divided into four groups: control group; Group (P) were administrated oral propolis (100 mg/kg once daily for 28 days); Group (P+DOX) were injected with a single intraperitoneal dose of DOX (20 mg/kg i.p at 24th day after the propolis administration) and group (DOX) were injected with doxorubicin only. Estimation of cardiac, renal and hepatic injury markers, apoptosis and pro-inflammatory cytokines were done using sera. Also, liver and heart tissue samples were collected to determine GSH and MDA as oxidative stress markers. In addition to histopathological and immunohistochemical examination of Cytochrome-C and Connexin43 on lysed myocardium, liver, kidney and lung tissues. Doxorubicin toxicity caused marked deteriorations of measured parameters through the different mechanisms in different body organs. However, pre-treatment with propolis significantly ameliorated these alterations. Thus propolis can ameliorate the DOX-induced experimental multi-toxicity as cardiomyopathy, hepatotoxicity, nephritis and pneumonia. Thus, it could be a promising protective agent in DOX treatment protocols.

Objective. To explore the protective effect and mechanism of rosuvastatin on acute renal injury induced by a nonionic hypotonic contrast medium in rats. Methods. Forty-eight healthy adult SD rats were randomly divided into three groups: normal control group (NC); contrast medium control group (CM); and rosuvastatin intervention group (RI). The RI group was intragastrically administered with a 10 mg/kg of rosuvastatin 12 h prior to the contrast exposure. All rats in CM and RI groups were inoculated with 10 mL/kg of chemical (IV) while the same volume of saline for the NC group. At 24 h and 72 h posttreatments, pathomorphological changes of renal tubules were documented, respectively, and several biochemical indicators were tested to assess renal injury of experimental rats. Results. Compared with the CM group, rats in the RI group showed significantly reduced injury of kidneys and decreased levels of biochemical indicators such as blood Scr, blood Cys-C, urine NAG, urine α1-MG, and urine mALB. The serum Hs-CRP in the CM group increased significantly from 24 h to 72 h (p<0.05), but this was not observed in the rats of the RI group. In addition, SOD activity in the RI group was significantly increased (p<0.01) while SOD activity in renal tissue decreased significantly with time in the CM group (p<0.05). Conclusion. Short-term intervention with rosuvastatin can lead to reduced kidney damage associated with the contrast agent by reducing the levels of inflammatory factors and oxidative stress. Thus, rosuvastatin intervention has a protective effect on rats from contrast-induced nephropathy.

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.

Rotenone, an insecticide of botanical origin, causes toxicity through inhibition of complex I of the respiratory chain in mitochondria. This study was undertaken to determine whether rotenone-induced liver oxidant injury is prevented by erdosteine, a mucolytic agent showing antioxidant properties. There were four groups of Male Wistar Albino rats: group one was untreated as control; the other groups were treated with erdosteine (50 mg/kg per day, orally), rotenone (2.5 mg/mL once and 1 mL/kg per day for 60 days, i.p.) or rotenone plus erdosteine, respectively. Rotenone treatment without erdosteine increased xanthine oxidase (XO) enzyme activity and also increased lipid peroxidation in liver tissue P < 0.05). The rats treated with rotenone plus erdosteine produced a significant decrease in lipid peroxidation and XO activities in comparison with rotenone group PB / 0.05). Erdosteine treatment with rotenone led to an increase in catalase (CAT) and superoxide dismutase (SOD) activities in comparison with the rotenone group PB / 0.05). There was no significant difference in nitric oxide (NO) level between groups. There were negative correlations between CAT activity and malondialdehyde (MDA) level (r= -0.934, P <0.05) with between CAT and SOD activities (r= -0.714, P <0.05), and a positive correlation between SOD activity and MDA level (r= 0.828, P <0.05) in rotenone group. In the rotenone plus erdosteine group, there was a negative correlation between XO activity and NO level in liver tissue (r= -0.833, P -0.05). In the light of these findings, erdosteine may be a protective agent for rotenone-induced liver oxidative injury in rats.

Abstract The effects of natural clinoptilolite (NCLI) and modified clinoptilolite (MCLI) were evaluated in broilers challenged with lipopolysaccharide (LPS) in a 21-d feeding trial. A total of 288 one-day-old chickens were allocated into three treatment groups: control, NCLI (2%) and MCLI (2%). Half of the birds from each treatment group were challenged with either 0.9% NaCl solution or LPS (250 μg/kg body weight, orally administered) at 16, 18 and 21 d of age. Before the LPS challenge, no dietary effect on bird growth performance was found (P>0.05). When LPS was orally administered, no significant changes in growth performance of broilers was found (P>0.05). However, small intestinal morphology and development, malondialdehyde (MDA) content of the jejunual and ileal mucosa, and superoxide dismutase (SOD) activity of the ileal mucosa were significantly affected (P<0.05). Supplementation with NCLI and MCLI significantly decreased the MDA contents of the jejunual and ileal mucosa and improved the SOD activity of the ileal mucosa and the development of the small intestine compared with the control group (P<0.05). The results indicated that NCLI and MCLI additions in feed had protective effects on the gut health of broilers against LPS challenge.

Fluoride naturally occurs in the earth’s crust and ground water and it causes fluorosis when it is consumed in high levels. The fluorosis also affects soft tissues like liver, kidney, heart, brain etc., in addition to skeletal and dental systems. The present study reports the protective effects of selenium against sodium fluoride induced neurotoxic effects. Three months old (around 250 – 280 g weight) wistar rats were randomly categorized into four groups viz. Group I (control) which received normal tap water, Group II (sodium fluoride, NaF) treated with 20 ppm of fluoride through IP, Group III treated with (NaF 20 ppm) + Selenium (5 mgkg-1 body wt./day/rat) and Group IV treated with Selenium (5 mgkg-1 body wt./day/rat) alone. The doses were continued for a period of 15 days and after that they were used for recording behavioral (rota rod, hot plate), anti-oxidant (LPO, SOD, CAT and GSH-Px) and histological (Golgi cox staining) observations. The rats treated with NaF showed the decreased motor coordination, thermal pain response, decreased CAT and SOD activity and increased LPO levels and GSH-Px activity with compared to control group. Moreover, NaF received rats also showed the decreased number of dendrites, synaptic connections and neural networks. These all alterations were reversed on administration of selenium towards fluoride toxicity and the results were significant (p<0.01). The results of selenium alone treated group of rats is comparable to control group. Based on these observed results, the present study evidenced the protective role of selenium against fluoride induced neurotoxicity.
