AbstractLiver and kidney diseases are becoming order of the day in both developed and developing countries as a result of environmental pollutants such as lead. Restorative activities of methanol and methanol/acetone phenolic-rich extracts (MPR and MAPR, respectively) of the N. latifolia fruit (NLF) on lead acetate-induced liver and kidney damaged were assessed in Wistar rats. The antioxidant activities of both phenolic-rich extracts of NLF were also carried out using standard methods. Seven groups of Wistar rats comprising of 5 rats each were used for the study and 1000 mg/kg body weight (bw.) of lead acetate solution was administered orally to the 6 groups of animals to induce liver and kidney damage. The high and low dosages of 300 and of 150 mg/kg body weight (bw.) of both MPR and MAPR were administered orally to four groups for 14 days along positive (100 mg/kg bw. of silymarin), negative (treated with the placebo) and naïve control (non-induced). The percentage DPPH radical scavenging activities, ferric reducing antioxidant power and percentage inhibition of lipid peroxidation show high antioxidants activities dose-dependently. Furthermore, administration of lead acetate significantly (p > 0.05) reduces the weight gain and elevates the liver and kidney relative weight as well as their respective damage biomarkers with distortions in their histologies. However, treatment with MPR and MAPR resulted in significant (p < 0.05) improve in the percentage body weight gain, relative liver and kidney weight as well as restoration of the activities of the liver and kidney functions biomarkers of the treated animals. Likewise, lesser hepatic and renal cells injury were also observed in the treated groups with MAPR being more active at high dosage which significantly (p < 0.05) compared well with normal group. Hence, the phenolics content of the N. latifolia fruit can be exploited further for drug development for the management kidney and liver damage arise from lead-induced toxicity.

Scoparia dulcis (Linn) is a widespread herbal medicine; it bears an enormous number of pharmacological activities. The present study was undertaken to find out the chronic toxicity profile of oral administration of Scoparia dulcis ethanol leaf extract (SDELE) on the liver and the kidney of wistar rats. The animals were grouped into four and administered varying doses of SDELE (100 mg/kg, 200 mg/kg, 400 mg/kg body weight and 0.2 ml distilled water respectively) for a period of fourteen weeks (100 days). The acute toxicity, body weight, relative organ weight, hematological parameters, biochemical markers for liver and kidney damage were monitored and histopathology of the liver and kidney of the rat were carried out. The LD50 of SDELE was found to be 1131 mg/kg body weight. There was a significant (p<0.05) reduction in weight of the rat administered 400 mg/kg and 200 mg/kg when compared with the control though there was no significant difference (p>0.05) in the relative weight of the organs. There was also a significant increase (p<0.05) in the lymphocytes, serum level of aspartate amino transferase (ASP), alanine amino transferase (ALT), alkali phosphatase (ALP), total protein, A/G ratio, creatinine, urea, uric acid, total cholesterol, triacylglycerol, low density lipoprotein cholesterol and potassium ions while there was a significant decrease in HDL-cholesterol and sodium ions in the animal group administered 400 mg/kg body weight of the extract. Histopathology of the liver and kidney revealed haemorrhage and vascular congestion at 200 mg/kg doses and renal damage at 400 mg/kg body weight doses respectively. However, there was no significant difference (p>0.05) in any of the parameters studied in the group administered 100 mg/kg body weight dose when compared with the controlled group. Ethanol leaf extracts of Scoparia dulcis showed hepatotoxic and nephrotoxic tendencies and should be used with caution especially when employed in the treatment of chronic diseases

Different Doses

The treatment during the embryonic preimplantation phase of Wistar rats with thePradosia huberiextract did not interfere with the water and feed consumption, as well as upon the body-weight gain. However, it has expressed a decrease of the uterine implant number, followed by the preimplantation losses at all applied doses (1.22, 6.1, and 30.5 mg/kg), and the number of embryonic resorptions in the two highest doses (6.1 and 30.5 mg/kg). After the organ weighing (hypophysis, ovaries, and uterus), only the relative weight of the hypophysis was raised at the different doses (1.22, 6.1, and 30.5 mg/kg). It was concluded that the hydroalcoholic extract ofPradosia hubericompromises the reproductive ability during the embryonic preimplantation phase, suggesting a possible toxic effect upon the reproductive system of Wistar rats.

Immune System Development

Studies have revealed that impairment of the pregnant body weight reduces the fetal body weight and causes minor changes in skeletal development. The aim of the present study was to assess the effects of maternal feed restriction during pregnancy in offspring immune system development. Pregnant Wistar rats were distributed into 5 groups: 1 control in which dams received food ad libitum and 4 experimental groups in which dams were fed restricted amounts of rodent ration (16, 12, 9, or 6 g/rat/day) from the 6th to 17th gestation day. Teratogenicity was assessed using classical teratological evaluation and developmental immunotoxicology protocols. Maternal body weight gain, fetus weight, and placenta weight were reduced for feed-restricted females from the groups fed 12, 9, and 6 g/rat/day ( p < 0.05). No pup mortality was observed immediately after cesarean sections among the groups, and no visceral or skeletal malformations were detected. An immunoteratological study revealed an increase in the relative weight of the thymus and an increase in the phorbol myristate-acetate solution-induced hydrogen peroxide release by inflammatory cells in 21-day-old pups. Alterations in the delayed-type hypersensitivity response and the humoral immune response against sheep red blood cells were observed in pups from feed-restricted mothers. Feed restriction in Wistar rats during organogenesis did not promote structural malformations but resulted in offspring with lower birth weights and promoted significant changes in the immune responses of the rat pups.

The Impact

The impact of lead toxicity was assessed in this study by analyzing the effects of the extracts on some electrolytes, urea and creatinine concentration. Thirty-five male wistar rats (150+50g) were distributed into five groups with seven rats in each group. Extraction and all biochemical analysis were carried out using standard laboratory techniques. Group one served as control, group two as test and were exposed to lead acetate only. Groups three, four and five were treatment groups, administered carrot and garden egg, carrot and tomato, garden egg, carrot and tomato respectively. All groups received feed and water ad libitum. Lead Acetate solution was administered orally at 50mg/kg body weight while 200mg/kg body weight received mixed juicy extract. On day 15, food was withdrawn, fasted overnight with free access to water. They were euthanized under chloroform vapor and sacrificed. Whole blood was collected via cardiac puncture for biochemical analysis. There was significant (P<0.05) decrease in potassium and chloride ion in group 2 (test group), compared to the control and treatment groups. Concentration of urea and creatinine in the test group was significantly higher compared with the other groups. Concentration of creatinine in group 3 and 5 significantly increased compared to control group. Effect of lead acetate was significantly reversed in group 5 compared to group 2. The results of the study indicate the potency of plants extracts against toxicity caused by the lead acetate. Flavonoids, saponins, tannins and alkaloids were present in the extracts.

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.

Protein Concentrate

The effect of feed protein type on body composition and growth has been examined. Evidence exists that whey protein concentrate is effective at limiting body fat expansion. The presence of caseinomacropeptide, a mixture of glycosylated and non-glycosylated carbohydrate residues, in particular glycomacropeptide (GMP) in whey protein concentrate may be important for this effect. The influence of whey protein isolate (WPI) and GMP on weight gain and body composition was examined by feeding Wistar rats ad libitum for 7 weeks with five semi-purified American Institute of Nutrition-based diets differing in protein type: (1) casein; (2) barbequed beef; (3) control WPI (no GMP); (4) WPI+GMP at 100 g/kg; (5) WPI+GMP at 200 g/kg. Body composition was assessed, and plasma samples were assayed for TAG, insulin and glucose. Body-weight gain was lower ( − 21 %) on the control WPI diet relative to casein, with a non-significant influence associated with GMP inclusion ( − 30 %), the effect being equivalent at both levels of GMP addition. Renal and carcass fat mass were reduced in the highest GMP diet when compared with WPI (P < 0·05). Plasma insulin was lowered by GMP at the highest addition compared with WPI alone ( − 53 %; P < 0·01). Plasma TAG in the WPI+GMP (200 g/kg) group were lower ( − 27 %; P < 0·05) than the casein and beef groups. In conclusion, GMP appears to have a significant additional influence when combined with WPI on fat accumulation. WPI alone appears to have the predominant influence accounting for 70 % of the overall effect on body-weight gain. Mechanisms for this effect have not been identified but food intake was not responsible.

An inhibitor of α-amylase was isolated and purified from an extract of white kidney beans (Phaseolus vulgaris). The acute oral administration of the inhibitor (50 mg/kg body weight) to adult Wistar rats together with a starch load (2 g/kg body weight suspended in NaCl (9 g/l)) reduced the increase in glycaemia over the basal value (NaCl, 222 (SEM 49); inhibitor, 145 (SEM 16) mmol/l×180 min; P<0.05) without modifying the insulin response. On administering the inhibitor orally (50 mg/kg body weight dissolved in NaCl (9 g/l)) for 21 d to rats fed on a standard diet, a decline was observed in the glycaemia values on day 0 (NaCl, 5.53 (SEM 0.12); inhibitor, 5.25 (SEM 0.16) mmol/l) relative to those obtained on days 10 (NaCl, 5.00 (SEM 0.14); inhibitor, 4.60 (SEM 0.08) mmol/l; P<0.05) and 21 (NaCl, 5.22 (SEM 0.22); inhibitor, 4.50 (SEM 0.12) mmol/l; P<0.01) of treatment, without modifying the plasma concentration of insulin. There was found to be a significant anorexigenic action of the inhibitor; there was reduced food intake (NaCl, 23.07 (SEM 0.31); inhibitor, 19.50 (SEM 0.49) g/d; P<0.01), a reduced weight gain (NaCl, 52 (SEM 3); inhibitor, −1.33 (SEM 8.9) g/21 d; P<0.01), as well as changes in the activity of some intestinal enzymes such as maltase (NaCl, 87 (SEM 7); inhibitor, 127 (SEM 11) U/g proteins; P<0.05). The present study has shown, for the first time, that the prolonged administration of an α-amylase inhibitor reduces blood glucose levels and body-weight gain in Wistar rats.

Abstract The prenatal exposure to selective serotonin reuptake inhibitors (SSRIs) is very controversial. There is no conclusive evidence for increased risk of malformations after SSRI use in pregnancy. The aim of the study was to determine how fluoxetine is affecting gestation and fetal development in rats. Twenty sexually mature female Wistar rats weighting between 250-260 g received 20 mg/kg body weight fluoxetine from the first day of gestation and during the entire gestation period.The drug was administered by oral route. Healthy, primipareus animals were selected along with 20 female Wistar rats, as control group. Mature males were caged with virgin females for an entire week. Rat’s behaviour during gestation, after birth and rats body weight was examined. The number of healthy pups was also noted. The females not giving birth after 21 days to any pup were anesthetized (halothane through gas scavenging apparatus untilled death) and the gravid uterus were dissected out and examined. Compared to the controlled group, in which weight gain was more significant, the animals from the experimental group had a slight increase in body weight. The weight gain normally induced by gestation, is less significant in fluoxetine treated rats due to the increase serotonin levels in the brain. The uteri examination of pregnant rats showed an increase in the number of dead and resorbed rat embryos. Preclinical studies suggest that the inclusion of fluoxetine in pregnancy category C is justified and the appropriateness of its administration in pregnancy is still an unresolved issue.

Background: Medicinal plants are of great importance to health of individual and communities. About 80% of the population in Uganda relies on traditional medicine because western-trained medical personnel are limited especially in villages. Most Ugandans use Hymenoxys odorato for medicinal purposes e.g. to treat colds, fever, coughs, anti-helminthes, locally used as tea, anti-allergy and also as an anti-venom to relieve snake bites. Method: A group of 25 male wistar rats of 150 g&ndash;210 g were kept for 14 days while being fed and treated with the extract. At 14th day, anesthesia was given and blood samples collected by cardiac puncture for hematological and biochemical investigations. Serum was analyzed for Alkaline Phosphatase, Aspartate Transaminase and Alanine Transaminase while whole blood was used for complete blood count. The liver and kidney were removed and placed in 10% formalin to prepare for histology staining using haematoxylin and eosin technique. Results: The extract elevated hepatic biomarker enzymes i.e. ALP, ALT and AST. The increase was found to be significantly different (P &gt; 0.05) at 400 and 500 mg/kg doses as compared to the control group. Histological sections of the liver showed distortion of liver cytoarchitecture, steatosis, necrosis of hepatocytes and congestion of the sinusoids at high doses 300, 400 and 500 mg/kg body weight. In the sections of the kidney, there was mild distortion of the integrity of the kidney with glomerular hypercellularity at high doses (400 and 500 mg/kg per body weight). Conclusion: Hymenoxys odorato aqueous extract has toxic effects on the liver and kidney of wistar rats. The effects were observed to be in a dose dependent manner.
