Introduction: Doxorubicin (DOX), a well-known chemotherapeutic drug, has been reported to induce numerous toxic side effects including renal toxicity. This preliminary study was designed to investigate the ameliorative effects of methanolic leaf extract of Clerodendrum volubile (MECV) against DOX-induced nephrotoxicity in rats. Methods: Thirty male rats were divided into five groups; (a) Control group: rats were given 0.9% NaCl as vehicle, (b) DOX group: a single dose of DOX (25 mg/kg; i.p.) was administered and the rats were sacrificed 4 days after DOX injection, (c-e) Methanolic extract of C. volubile (MECV)-treated DOX groups: rats were given MECV (at the doses of 125, 250 and 500 mg/kg/d), respectively for 12 consecutive days, 8 days before and 4 days after the DOX administration. Results: DOX injection caused a significant increase (P<0.05) in serum creatinine and urea levels. The levels of renal antioxidant parameters: glutathione peroxidase, superoxide dismutase (SOD), catalase (CAT) and reduced glutathione were significantly (P<0.05) decreased in DOX-intoxicated rats with concomitant elevation of malondialdehyde level. Pretreatment with MECV restored antioxidant status, attenuated oxidative stress and improved kidney function markers. Pre-treatment with MECVprotected renal tissues against DOX-induced nephrotoxicity. Conclusion: The ameliorative effects of C. volubile leaves on these renal biochemical parameters may be via its antioxidant action and may serve as a novel combination agent with DOX to limit its renal damage.

Hypertension is a condition where there is an abnormal rise in blood pressure that may be the primary cause of cardiovascular disease. Hypertension induces the production of free radicals known as reactive oxygen species (ROS) and oxidative stress. The purpose of this study is to further examine the function of Dendropthoe pentandra as an endogenous antioxidant modulator in this case superoxide dismutase (SOD) in hypertensive rats.The testing approach used is experimental. Data were analyzed using the one-way ANOVA test and the Post Hoc test to see variations in SOD levels in different treatments. This research used a hypertensive rat model induced by deoxycorticosterone acetate (DOCA) and salt. The number of animals tested was 25 white male rats divided into 5 groups, each containing 5 rats.The group consisted of a control group, a group of non- Extract methanolic of mango mistletoe hypertensive rats, and three groups of hypertensive rats receiving mango mistletoe methanolic extract (EMBM) at dosages of 50 mg/kg, 100 mg/kg, and 200 mg/kg body weight. Based on the results of the study, it is known that the levels of increased lung SOD with extract methanolic of mango mistletoe dosage variations in all treatment groups were not different. The administration of mango parasite methanolic extract at a dose of 50 mg / kgBW was optimum in increasing lung SOD levels in hypertensive rats.

Abstract Objectives Doxorubicin (DOX) is a commonly used chemotherapeutic drug. However, its non-target organ toxicities pose a serious problem. This study is to assess the protective role of Clerodendrum volubile leaf extract (CVE) against DOX-induced toxicities in rats. In addition, the inhibitory activities of three phytochemical compounds (Rutin, Gallic acid and Rosmarinic acid) from CVE against Carbonyl reductase 1 (CBR1) were examined. Methods Rats were randomly divided into 5 groups: (a) Control group rats were given 0.9% NaCl as vehicle, (b) DOX group: A single dose of DOX (25 mg/kg; i.p.) was administered and rats were sacrificed 4 days after DOX injection, while groups (c–e) CVE-treated DOX rat groups were given 125, 250 and 500 mg/kg body weight of extracts orally for 12 consecutive days; 8 days before, and 4 days after the DOX administration. Computational techniques were used to determine the inhibitory activities of the compounds against CBR1. Results DOX intoxication caused a significant increase (p<0.05) in serum marker enzymes: ALT, AST, ALP, LDH, CK activities. The levels of liver and heart tissues antioxidant parameters: GPx, SOD, CAT, and GSH were significantly (p<0.05) decreased in DOX-intoxicated rats with concomitant elevation of malondialdehyde levels. Pretreatment with CVE reversed the above trends. From the structural analysis, Rutin and RSA exhibited the highest binding free energies against CBR1, and also exhibited structural stability when bound with CBR1. Conclusions Our study indicates the protective effect of CVE when used in combination with doxorubicin thus improving its chemotherapeutic application via inhibition of CBR-mediated metabolism.

Phytochemical composition and antioxidant activity of flowers decoction at post-flowering stage (F3D) of Opuntia dejecta were determined. The obtained findings demonstrate that F3D has a marked antioxidant activity in all tested assays. Furthermore, the present study was designed to test the protective activity of F3D against induced Diabetes type 2 (DT2) in male rats. Those metabolic syndromes were induced by a high-fructose diet (HFD) (10% fructose solution) for a period of 20 weeks. F3D was administered orally (100 and 300 mg/kg body weight) daily for the last 4 weeks. Metformin (150 mg/kg body weight) was used as a standard drug and administrated orally for the last 4 weeks. The results showed a significant increase in blood glucose, triglycerides and hepatic markers (ALAT, ASAT and ALK-P) in HFD group. A significant increase in hepatic TBARS and a significant decrease in SOD, CAT and GPX were observed in fructose fed rats compared to control group. Administration of F3D showed a protective effect in biochemical and oxidative stress parameters measured in this study. Also, oral administration of F3D restored the histological architecture of rat liver in comparison with rats fed HFD. In conclusion, F3D attenuated hepatic oxidative stress in fructose-fed rats.

In this study, experimentally lindane-induced histopathological changes and proliferation and/or apoptosis in germ cells in the rat testes were investigated. A total of 40 healthy fertile 3-month-old male rats were used. Animals were divided into 4 groups, each containing 10 rats. Group 1 (control) was given only pure olive oil, Groups 2, 3 and 4 were administered lindane at 10, 20 and 40 mg/kg/bw, respectively, by gastric gavage for 30 days. Microscopically, degenerative changes were observed in the lindane-treated groups. For proliferative activity PCNA immunolabelling and for germ cells apoptosis TUNEL methods were performed. Although a strong PCNA positivity in the control group was observed, a gradual decrease was noted in the lindane-treated groups especially at higher doses. Significant increases of apoptosis were seen in the lindane-treated groups compared to the control group. A decrease in testosterone concentrations was observed in lindane-treated groups compared to the control group. The study indicates that high-dose lindane intoxication contributes to the suppression of spermatogenesis through a reduction of germ cell proliferation and an increase of germ cell death in rat testes.

Abstract Objectives Several studies have established the ethnobotanical benefits of Pupalia lappacea (PL) in laboratory animals without extensive toxicological evaluation of its safety profiles. Thus, an extensive toxicological investigation of sub-chronic oral administration of the hydroethanol leaf extract of P. lappacea in rodents was carried out in this study. Methods Different groups of rats were treated orally with the extract (10, 50 and 250 mg/kg) daily for 90 consecutive days. The control group received distilled water (10 mL/kg). After 90 days, some rats were left for additional 30 days without treatment for reversibility study. Blood and organs samples were collected for different evaluations at the end of study periods. Results The extract decreased the bodyweights, feeding and water intakes in female rats. PL increased the weights of the liver and kidney in male rats. PL increased the red blood cell (RBC), packed cell volume (PCV), hemoglobin (Hb), triglycerides (TRIG), cholesterol and high density lipoprotein (HDL) contents in rats. PL (250 mg/kg) significantly reduced the sperm motility and serum testosterone level. Cyto-architectural distortions of the testes, liver and spleen were visible. Conclusions The findings showed that P. lappacea is relatively safe at lower doses but cautions should be taken at higher dose.

PURPOSE: To evaluate and to compare macro and microscopically the intense injuries of the gastric mucosa of rats which were caused by NSAIDS celecoxib and indomethacin and the gastric cytoprotection with omeprazole and misoprostol. METHODS: The sample is formed by one hundred and fifty Wistar rats with average weight 200 g, distributed in four groups, such as: Group A, subdivided in groups A1 and A2 - pre-treatment with omeprazole (20 mg/rat) during seven days and on the 8th day - use of NSAIDS, concerning A1 (20 rats) were given celecoxib (1mg/rat) and A2 (20 rats) were given indomethacin. The Group B, subdivided in group B1 and B2 - pre-treatment with misoprostol (20mg/rat) during seven days and on the 8th day use of NSAIDS, concerning B1 (20 rats) were given celecoxib (1 mg/ rat) and B2 (20 rats) were given indomethacin (12.5 mg/rat). The Group C: were not given cytoprotection during seven days, from the 7th to the 8th day - fast of food and water ad libitum, on the 8th day of NSAIDS use, concerning C1 (20 rats) were given celecoxib, C2 (20 rats) were given indomethacin (12.5 mg/ rat), C3 (20 rats) were given celecoxib (200mg/rato), and Group D - control group, concerning 10 rats were observed during seven days ingesting food and water ad libitum. On the 9th day, the stomachs were taken out and were macro and microscopically evaluated for the identification of the gastric injuries. RESULTS: On the macroscopic studies, the groups A2, B2 and C2 presented a remarkable high number of injuries for cm² /animal, respectively 18.55 injuries for cm² /animal, 16.25 injuries for cm² /animal and 13.55 injuries for cm²/animal. On the microscopic studies, the percentage of the injured mucosa, presented expressive difference among the groups A1, B1, C1 when compared to the groups A2, B2, C2 (p<0.0001). The average of the length/injury and the average of the depth of the injuries did not present expressive statistics differences among the groups A2, B2 and C2. The average of the edema presented expressive statistics difference among the groups A2 and D; B2 and C2 and between C2 and D (p < 0.05). CONCLUSIONS: The indomethacin on the applied concentration causes a great number of macroscopic and microscopic injuries to gastric mucosa of rats when compared to celecoxib which does not cause lesions. Omeprazole and misoprostol on the applied concentrations do not present macroscopic and microscopic effectiveness on the gastric cytoprotection when applying indomethacin. Considering the microscopic analysis of the average of the edema, the group of animals, which was given misoprostol as cytoprotection, presented a lower average compared to the group which was given omeprazole.

The Impact

It is common for food to be made more palatable through the use of the flavour enhancer monosodium glutamate, also known as vetsin powder. The purpose of the study described in this paper was to explore how vetsin-induced hepatic toxicity, DNA fragmentation, damage, and oxidative stress modifications could be mitigated with moringa leaf extract (MLE). To that end, 40 male rats were separated into four groups: normal control, positive control or MLE, vetsin, and vetsin combined with MLE. Results indicated that, compared to the control group, the levels of serum alanine aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), liver malondialdehyde (MDA), DNA damage, injury, PCNA, and P53 expressions were significantly enhanced by the administration of vetsin (P<0.05). However, the vetsin group had significantly reduced levels of albumin, globulin, total protein, liver glutathione (GSH), superoxide dismutase enzyme (SOD), catalase, and glutathione S-transferase (GST) enzyme activities (P<0.05) by comparison to control. Meanwhile, modifications in liver functions, oxidative stress, DNA damage, liver injury, and PCNA expression were alleviated when vetsin was administered alongside MLE. The authors conclude that vetsin may have many side effects and that MLE can ameliorate biochemical changes, oxidative stress, hepatic injury, PCNA, and P53 alterations induced by vetsin administration.

Abstract Objective: Neurotoxicity is an adverse effect caused by cisplatin due to inflammation and oxidative stress in the central nervous system. The present study aimed to assess the effects of vitamin E injection on the learning and memory of rats with cisplatin-induced cognitive impairment. Methods: Male rats were administered with cisplatin (2 mg/kg/7 day; intraperitoneally [i i.p.]) and/or vitamin E (200 mg/kg/7 day; i.p.) for 1 week, and the control group received saline solution. Spatial memory was evaluated using Morris water maze (MWM). In addition, the hippocampal concentrations of malondialdehyde (MDA), thiol, and superoxide dismutase (SOD) were measured using biochemical methods. Results: According to the findings, cisplatin significantly increased the escape latency, while decreasing the time spent and travelled pathway in the target quadrant on the final trial day compared to the control group. Furthermore, pre-treatment with vitamin E significantly reversed all the results in the spatial memory test. The biochemical data indicated that vitamin E could decrease MDA activity and increase thiol and SOD activity compared to the control group. Conclusion: According to the results, vitamin E could improve cisplatin-induced memory impairment possibly through affecting the hippocampal oxidative status.

Anthracycline antibiotic doxorubicin, which has proven cardiovascular toxicity, is often used in the treatment of cancer. The research project was carried out in 21 sexually mature Wistar male rats divided into three groups: control group, high-dose experimental group, in which rats were once injected intraperitoneally with doxorubicin hydrochloride at a dose of 10 mg/kg and low-dose experimental group, in which animals twice received intraperitoneal 2.5 mg/kg doses of doxorubicinhydrochloride at 10-day interval.An increase of malondialdehyde was revealed in the membranes of red blood cells in the high-dose experimental group, while in the low-dose experimental group a reduction in the levels of malondialdehyde and plasma hydroperoxides as well as a decreasing of catalase activity was observed. Intake of doxorubicin also causes venous hyperemia in wide areas of myocardiumalong with increasing of cardiomyocytic cross striation.
