Abstract Consistent consumption of high salt diet (HSD) has been associated with increased cellular generation of free radicals which has been implicated in the derangement of some vital organs and etiology of cardiovascular disorders. This study was designed to investigate the combined effect of some commonly employed medicinal plants on serum lipid profile and antioxidant status of aorta, kidney, and liver of high salt diet-fed animals. Thirty-five male Wistar rats were divided into 5 groups of 7 animals each. Group 1 and 2 animals were fed normal rat and 16 % high salt diet only respectively. Animals in groups 3, 4, and 5 were fed 16% high salt diet with 800, 400, and 200 mg/kg bw poly-herbal extract (PHE) respectively once for 28 consecutive days. Serum low-density lipoprotein (LDL), triacylglycerol (TG), total cholesterol (TC) and high-density lipoprotein (HDL), malondialdehyde, nitric oxide, catalase, superoxide dismutase, glutathione peroxidase, glutathione concentration, and activities were assessed in the aorta, kidney, and liver. PHE (p < 0.05) significantly reduced malondialdehyde and nitric oxide concentration and increased antioxidant enzymes and glutathione activity. Elevated serum TG, TC, LDL, and TC content in HSD-fed animals were significantly (p < 0.05) reduced to normal in PHE-treated rats while HDL was significantly elevated (p < 0.05) in a concentration-dependent manner in PHE treated animals. Feeding with PHE attenuated high salt diet imposed derangement in serum lipid profile and antioxidant status in the organs of the experimental rats.

Consistent consumption of high salt diet (HSD) has been associated with increased cellular generation of free radicals, which has been implicated in the derangement of some vital organs and etiology of cardiovascular disorders. This study was designed to investigate the combined effect of some commonly employed medicinal plants on serum lipid profile and antioxidant status of aorta, kidney, and liver of high salt diet-fed animals. Out of the total fifty male Wistar rats obtained, fifteen were used for acute toxicity study, while the remaining thirty-five were divided into 5 groups of 7 animals each. Group 1 and 2 animals were fed normal rat chow (NRC) and 16% high salt diet (HSD) only, respectively. Animals in groups 3, 4 and 5 were fed 16% HSD with 800, 400, and 200 mg/kg bw poly-herbal extract (PHE), respectively, once for 28 consecutive days. Serum low-density lipoprotein (LDL), triacylglycerol (TG), total cholesterol (TC) and high-density lipoprotein (HDL), malondialdehyde, nitric oxide, catalase, superoxide dismutase, glutathione peroxidase, glutathione concentration, and activities were assessed in the aorta, kidney, and liver. Poly-herbal extract (p < 0.05) significantly reduced malondialdehyde and nitric oxide concentrations and also increased antioxidant enzymes and glutathione activity. Elevated serum TG, TC, LDL, and TC content in HSD-fed animals were significantly (p < 0.05) reduced to normal in PHE-treated rats while HDL was significantly elevated (p < 0.05) in a concentration-dependent manner in PHE treated animals. Feeding with PHE attenuated high-salt diet imposed derangement in serum lipid profile and antioxidant status in the organs of the experimental rats.

High-salt (HS) diets have recently been linked to oxidative stress in the brain, a fact that may be a precursor to behavioral changes, such as those involving anxiety-like behavior. However, to the best of our knowledge, no study has evaluated the amygdala redox status after consuming a HS diet in the pre- or postweaning periods. This study aimed to evaluate the amygdala redox status and anxiety-like behaviors in adulthood, after inclusion of HS diet in two periods: preconception, gestation, and lactation (preweaning); and only after weaning (postweaning). Initially, 18 females and 9 male Wistar rats received a standard (n = 9 females and 4 males) or a HS diet (n = 9 females and 5 males) for 120 days. After mating, females continued to receive the aforementioned diets during gestation and lactation. Weaning occurred at 21-day-old Wistar rats and the male offspring were subdivided: control-control (C-C)—offspring of standard diet fed dams who received a standard diet after weaning (n = 9–11), control-HS (C-HS)—offspring of standard diet fed dams who received a HS diet after weaning (n = 9–11), HS-C—offspring of HS diet fed dams who received a standard diet after weaning (n = 9–11), and HS-HS—offspring of HS diet fed dams who received a HS diet after weaning (n = 9–11). At adulthood, the male offspring performed the elevated plus maze and open field tests. At 152-day-old Wistar rats, the offspring were euthanized and the amygdala was removed for redox state analysis. The HS-HS group showed higher locomotion and rearing frequency in the open field test. These results indicate that this group developed hyperactivity. The C-HS group had a higher ratio of entries and time spent in the open arms of the elevated plus maze test in addition to a higher head-dipping frequency. These results suggest less anxiety-like behaviors. In the analysis of the redox state, less activity of antioxidant enzymes and higher levels of the thiobarbituric acid reactive substances (TBARS) in the amygdala were shown in the amygdala of animals that received a high-salt diet regardless of the period (pre- or postweaning). In conclusion, the high-salt diet promoted hyperactivity when administered in the pre- and postweaning periods. In animals that received only in the postweaning period, the addition of salt induced a reduction in anxiety-like behaviors. Also, regardless of the period, salt provided amygdala oxidative stress, which may be linked to the observed behaviors.

Diabetes mellitus is a common risk factor for erythrocyte osmotic stress. This study was aimed at exploring the effect of streptozotocin (STZ)-induced diabetes mellitus and salt-induced hypertension on osmotic fragility and hemorheological variables in male Wistar rats. Thirty male rats were grouped into five groups of six animals each as follows: negative control (zero salt in diet); positive control (normal salt diet - 0.3% salt); high salt diet (8% salt) (HSD only); STZ induced diabetes and normal salt diet (STZ only); STZ induced diabetes and high salt diet (STZ + HSD). At the end of a 4 weeks period, hematological variables, osmotic fragility, rheology and cardiovascular responses were assessed. There was an increase (p<0.05) in the mean arterial pressure and heart rate of HSD, STZ and HSD + STZ groups indicating a salt induced hypertension. There was a decrease in the body weight of STZ and HSD +STZ groups. There was significant increase (p<0.05) in the haematocrit, platelets estimates and fibrinogen concentrations in the experimental groups when compared with the controls. The STZ and STZ + HSD groups showed a reduced clotting time which corresponded to the increased platelet estimates and fibrinogen concentration. The increase in haematocrit, platelet and plasma protein resulted in the increased blood viscosity and a decreased flow rate. The osmotic fragility test was also observed to be increased (p<0.05) in HSD, STZ only and STZ + HSD groups. Diabetes mellitus and hypertension increase the rate of hemolysis of erythrocyte, as well as increase blood viscosity.

Introduction This study was designed to show that Persea americana extract possess the ability to protect the myocardium of left ventricle against injury caused by high salt diet in adult Wistar rats. Method Forty healthy Wistar rats of both sexes weighing 120–150 g were randomly assigned into 8 groups of 5 rats each (Groups A, B, C, D, E, F, G and H). Rats in groups A, F, G and H were fed with standard laboratory pellets, while groups B, C, D and E were fed on the high-salt diet for four weeks. Concomitantly, daily administration of 50 mg kg-1, 100 mg kg-1 and 150 mg kg-1 of the Persea americana extract were given orally to groups C&F, D&G and E&H respectively while rats in groups A and B were administered distilled water. The rats were sacrificed under ketamine anesthesia (30mg/kg i.m). The left ventricle of the heart was excised, processed in paraffin wax and stained with haematoxylin and eosin and Verhoeff-Van Gieson stains. One-way ANOVA was used to analyze data, followed by Student Newman-keuls (SNK) test for multiple comparison. Result Results revealed that there was statistically significant (p < 0.05) difference in body weight change across all experimental groups; which was significantly lower in high salt fed groups. It was revealed that there were morphological alterations in the myocardium of left ventricle in group B while Persea americana protected myocardium in other experimental groups. Conclusion In conclusion, high salt diet induced myocardium alterations which were significantly protected by oral administration of Persea americana extract.

Background. The cardioprotective effects of Persea americana extract was investigated on biochemical activities of high salt–fed adult Wistar rats in this study. Method. Forty healthy Wistar rats of both sexes weighing 120 to 150 g were randomly assigned into 8 groups of 5 rats each (groups A, B, C, D, E, F, G, and H). Rats in groups A, F, G, and H were fed with standard laboratory pellets, while groups B, C, D, and E were fed on the high-salt diet for 4 weeks. Concomitantly, daily administration of 50, 100, and 150 mg/kg of the P americana extract were given orally to groups C and F, D and G, and E and H, respectively, while rats in groups A and B were administered distilled water. Blood samples were taken by cardiac puncture; concentration of sodium ion, potassium ion, nitric oxide, and activity of lactate dehydrogenase were determined. One-way analysis of variance was used to analyze data, followed by Student-Newman-Keuls (SNK) test for multiple comparison. Results. Results revealed that concentration of potassium ion and nitric oxide was significantly lower ( P < .05) in high salt–fed groups. Sodium ion concentration and activity of lactate dehydrogenase were higher in high salt–fed group while P americana prevented biochemical perturbations in other experimental groups. Conclusion. In conclusion, high salt–diet induced biochemical alterations which were significantly protected by oral administration of P americana extract.
