This study evaluated the activity of the ethanolic extract of pequi peel (EEPP) and immunostaining with matrix metalloproteinases 2 and 9 (MMP2 and MMP9), and tissue inhibitor of metalloproteinases 1 and 2 (TIMP1 and TIMP2) in the myocardium of rats subjected to acute cardiotoxicity using doxorubicin (DOX). Thirty Wistar rats (six groups of five animals) were used as follows: sham group (SG), water and saline; group G1, 16 mg/kg of DOX and 300 mg/kg of EEPP for 17 days; group G2, 16 mg/kg of DOX and 600 mg/kg of EEPP for 17 days; group G3, 16 mg/kg of DOX and 300 mg/kg of EEPP for 10 days; group G4, 16 mg/kg of DOX and 600 mg/kg of EEPP for 10 days; and control group (CG), 16 mg/kg of DOX. Three days after administering DOX (day 17), euthanasia was performed, and samples were collected for anatomopathological analysis. Myocyte vacuolar degeneration, cardiomyocyte disorganization and myofibrillar fragmentation, necrosis, mononuclear inflammatory infiltrate, Anitschkow cells, fibrosis, congestion, and edema were observed in the hearts of DOX recipients. In G1 and G2, EEPP attenuated myocyte vacuolar degeneration whereas in G4, EEPP attenuated cardiomyocyte disorganization. The percentage of cells immunoreactive for TIMP1 was higher in G1. It was concluded that EEPP minimizes the deleterious effects of DOX on rat myocardium. Doses of 300 and 600 mg/kg for 17 days attenuate the vacuolar degeneration of myocytes. The dose of 600 mg/kg for 10 days reduced cardiomyocyte disorganization, and the dose of 300 mg/kg for 17 days increased TIMP1 expression in the myocardium of DOX-treated rats.

The metabolic response to nutrient ingestion and the rate of digestion and absorption of nutrient molecules in bowel physiology plays an important role in the metabolic control of some human chronic non-infectious diseases. This experimentally-controlled designed nutritional study which lasted eight weeks aimed to determine the effects of proportional high-protein/low-carbohydrate (HP/LC) formulated diet on glycemic tolerance, glycemic control, body weight, organ weight and organ morphometry in healthy and diabetic adult male Wistar rats. Twenty-four male Wistar rats purchased from a disease-free stock were randomly categorized into four groups (n = 6, each) after two weeks acclimatization period in raised stainless steel cages with 6 mm2mesh floor and replaceable numbered blotters papers placed under each cage in a well-ventilated animal house. Animal groups include: Healthy control group (HC), Healthy treated group (HT), Diabetic control group (DC) and Diabetic treated group (DT. The animals were fed according to the experimental design with water ad libitumfor eight weeks. Diabetes was inducted with freshly prepared alloxan monohydrate solution (150 mg/kg bw, intraperitoneally). Body weights and fasting blood sugar concentrations were measured twice weekly, while oral glucose tolerance test was conducted on the last day of the eighth-week study and subsequently followed by organs extraction after anesthesia for weight and gross assessment. Proportional high-protein/low-carbohydrate formulated diet caused significant reduction in mean body weight of treated diabetic (DT: 22.6%; P= .001) and healthy (HT: 5.8%; P= .007) rats while the control animals on control diet recorded significant (P< .05) increase in body weight gain (DC: 12.4%; HC: 11.2%). Glycemic tolerance and control improved significantly in diabetic treated rats over that of the healthy treated rats. Gross morphometry of the extracted organs (kidneys, liver, heart, lungs, spleen and testes) revealed sustained normal morphological features without any visible lesion. In conclusion, consumption of proportional high-protein/low-carbohydrate formulated diet enhanced body weight reduction and sustained normal organ morphological features with good glycemic tolerance and control in experimental rats, suggesting its dietary potentiality, safety and suitability to ameliorate obesity-related diabetes.

The purpose of the study was to investigate the nephroprotective effect of the Myrmecodia pendans extract on Wistar rats. The nephrotoxicity of the animals was induced through intra-peritoneal administration of 100mg/kg/day of gentamicin for ten days. The effect of M. pendans extract at a dose of 250mg/kg/day was concurrently monitored in some rats by assessing their serum creatinine levels, blood urea nitrogen (BUN) and the histopathological parameters. The mean of serum creatinine in control group was 1.17±0.18mg/dl and in nephrotoxic group it was 2.22±0.29 mg/dl, while in group given the extract were 1.38±0.19 and 1.27±0.15mg/dl, respectively. In that group also sequentially showed BUN levels of 24.27±2.6, 108.13±11.58, 30.70±4.23 and 27.28±2.84mg/dl, respectively. Nephrotoxicity was induced in the animals injected with gentamicin, which showed a significant (P<0.05) increase in creatinine and BUN compared with control group. The results also showed that the M. pendans ethanolic extracts significantly (P<0.05) prevented the increase in the levels of serum creatinine, BUN and reduced renal histopathological damage such as hydropic degeneration, vascular congestion and tubular necrosis. Therefore, the ethanolic extract of M. pendans exhibits a nephroprotective activity.

The aim was to study the protective effect of ethanolic extract of Achillea millefolium on acute vascular injuries induced by cisplatin in liver, heart and renal tissues 24 hour after administration and using histopathological surveys in wistar rats. 24 adult male wistar rats were randomly divided into four groups. Group I (control group) received physiological saline for 10 days. Animals of group II had single dose of injection of CP (cisplatin) (6 mg/kg, IP) on the ninth day. Group III received Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days. Group IV had both Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days and a single dose of injection of CP (6 mg/kg, IP) on the ninth day. Kidney, liver and heart organs were collected on 10th day from sacrificed rats and subjected to histopathological analysis. Then the possible histopathological vascular effects of cisplatin on liver, heart, kidney tissues and the protective effect of Achillea millefolium extract was analysed. Obtained data showed the vascular injuries in CP group as congestion of cardiac capillaries (p=0.00) and interstitial edema (p=0.03). In the kidney, shrinkage of glomeruli (p=0.04), widening of Bowman's space (p=0.04), dilatation of cortical capillaries (p=0.01) were significantly altered. The findings of liver organ were increased sinusoidal space (p=0.00) and infiltration of neutrophils in portal space (p=0.01). Pretreatment with ethanolic extract of Achillea millefolium could attenuate these vascular injuries. Briefly, 24 hour after single injection of cisplatin the inflammatory process was seen in vital organs and administration of Achillea millefolium could mitigate these side effects.

ABSTRACT Trans fatty acids (TFAs) are the entire unsaturated fatty acids containing one or more double bonds isolated in trans configuration believed as predisposing factor of oxidative stress, excluding conjugated double bond fatty acids. Malondialdehyde (MDA) is a product of lipid peroxidation used as oxidative stress marker. The objective of this study was to see the correlation between TFAs containing-oil (consists of 3-6% TFAs) intake at various administration doses and pancreatic MDA levels in Wistar rats. Twelve rats were grouped according to administration doses (20%, 40%, 60% of given feed total energy and control group). TFAs containing-oil was administered orally once a day for 70 days at given doses by force feeding. Pancreatic MDA were measured using TBARS assay adapted from Singh et al. (2006). Increase of TFAs  containing-oil  administration  dose  caused  insignificant  increase  of  pancreatic MDA level.   Keywords: trans fatty acids, oxidative stress, malondialdehyde, Wistar rats, palm oil

PURPOSE: To evaluate the metabolic changes induced by pre-administration of L-alanyl-glutamine (L-Ala-Gln) and omega-3 (ω-3) in rats subjected to sepsis. METHODS: Eighteen male Wistar rats were randomized into three groups (n=6) and treated with saline (group Control-G-1), L-Ala-Gln (0.75 mg /kg , G-2) or ω-3 (0.2 g /kg, G-3 ) administered intravenously 3, 2 and 1 day and 30 minutes before induction of sepsis. Samples (blood, striated muscle and liver) were collected 48 hours after induction of sepsis, to measure the concentrations of metabolites (pyruvate, lactate, glucose and ketone bodies. RESULTS: There was a significant increase in muscle glycolysis and gluconeogenesis in the liver in rats treated with L-Ala-Gln and ω-3, compared to the control group, 48 hours after induction of sepsis. CONCLUSION: Pre-administration of L-Ala-Gln or ω-3 to rats subjected to sepsis resulted in similar metabolic changes, by rising glycolysis in peripheral tissues and stimulating hepatic gluconeogenesis and ketogenesis, resulting in increased energy supply to septic rats.

Objective: The objective of the study was to evaluate the antidepressant activity of ethanolic extract of dried leaves of Lagerstroemia speciosa L. (EELS) on acute restraint stress (ARS)-induced depression-like behavior and biochemical alterations in albino Wistar rats. Methods: Thirty rats were randomly divided into five experimental groups. Group-I (normal control) rats received normal saline (2.0 ml/kg, p.o.) daily for 14 days; Group-II (stress control) rats received normal saline (2.0 ml/kg, p.o.) daily for 14 days and subjected to restraint stress on the 13th day. Group-III (standard drug-treated) rats received imipramine (15 mg/kg, p.o.) daily for 14 days and subjected to restraint stress on the 13th day. Groups-IV and V rats were treated with EELS (100 mg/kg and 300 mg/kg, p.o.) daily for 14 days subjected to ARS on the 13th day. Stress-like behavior was assessed by subjecting the rats to behavioral paradigms such as tail-suspension test (TST) and open field test (OFT), 40 min post-restraint stress procedure. Pretest of 10 min for forced swim test (FST) was also given to each rat simultaneously. Then, 23.5 h later, the relevant samples were administered and the main test performed 30 min later. Oxidative stress parameters such as superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and extent of lipid peroxidation (LPO) were analyzed in restraint stress-induced animals and control group, following FST on the 15th day. Statistical Analysis: Expression of data was done as a mean standard error of the mean. The normally distributed data were subjected to one-way analysis of variance followed by Dunnett’s test. *p<0.05 was considered statistically significant. Results: It was observed that L. speciosa L. showed a significant dose-dependent decrease in duration of immobility time in TST and FST when compared with the control group in a dose-dependent manner. The results of OFT also showed a dose-dependent increase in locomotor activity. In addition to behavioral tests, EELS also normalized oxidative stress markers such as CAT, SOD, MDA, and LPO in a dose-dependent manner. Conclusion: The results suggest that the ethanolic extract of L. speciosa L. leaves possesses significant antidepressant property, may be recommended as a supplement for the antidepressant activity.

PURPOSE: To analyse histopathological alterations characterized by the mitotic index in the mucosa of the large intestine in Wistar rats submitted to jejunoileal bypass operation after continued administration of sodium nitrite and vitamin C to different groups. METHODS: Eighty male Wistar rats were employed and separated into 12 groups. In the control group (20 rats): five animals ingested only water; five animals received vitamin C; five animals received sodium nitrite and five received sodium nitrite + vitamin C. In the sham group (20 rats), the animals were anesthetized and underwent midline laparotomy and only intestinal manipulation was performed: five animals ingested only water; five animals received vitamin C; five animals received sodium nitrite and five received sodium nitrite + vitamin C. In the operated group 40 rats underwent a jejunoileal bypass surgery: ten animals ingested only water; ten animals received vitamin C; ten animals received sodium nitrite and ten received sodium nitrite + vitamin C. The mean weight of the animals was measured weekly. The large intestine was subdivided into cecum (S1), ascending colon (S2), transverse colon (S3), descending colon (S4) and rectum (S5) for histopathological analysis and mitotic counts. The statistical analysis was used to compare the mitotic indices. The level of significance was 5%. RESULTS: The mean of all the segments indicates that the sodium nitrite+vitamin C group obtained the lowest mitotic index compared to the other treatments in the control group. The segments S1 and S2 showed a statistical difference with the vitamin C treatment: a higher mitotic index and better preservation of the mucosa in the operated group. In the sham group the main statistical difference occurred only in the sodium nitrite+vitamin C group between the means of the segments. CONCLUSIONS: The comparison of all the colonic segments of the various groups revealed a lower mitotic index in the animals treated with sodium nitrite+vitamin C. In addition, it was found that vitamin C did not present a statistically significant inhibiting effect on the preservation of the mucosa and the mitotic index.
