Introduction: Lead is an environmental contaminant, which is toxic to organ systems in human and other animals. The present study investigated the possible protective role of Ficus carica leaf extract, vitamin C or the combined treatment in lead acetate-induced hepatotoxicity. Methods: One hundred and twenty-six adult male albino rats were divided into seven groups (n = 18). G1 (control group) received distilled water. G2 (lead acetate group) received lead acetate at a daily dose of 20 mg/kg body weight by gastric gavage. G3 (Ficus carica group) received Ficus carica leaves extract at a daily dose of 200 mg/kg body weight by gastric gavage. G4 (Ficus and lead group) received Ficus carica leaves extract followed by lead acetate after 20 minutes. G5 (vitamin C group) received vitamin C at a daily dose of 200 mg/kg body weight by gastric gavage, G6 (vitamin c and lead group) received vitamin C followed by lead acetate after 20 minutes. And, G7 (Ficus, vitamin C, and lead group) received Ficus carica leaves extract and vitamin C followed by lead acetate after 20 minutes. The treatment extended for six weeks, blood and specimens were collected at a 2-week interval. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total protein (TP), direct bilirubin (DB), lipid peroxidation biomarker (Malondialdehyde (MDA)), antioxidants enzymes (Superoxide dismutase (SOD) and reduced glutathione (GSH)) in liver tissue and histopathological changes in liver were investigated. Results: Lead acetate caused significant increases in AST, ALT, ALP, DB and MDA levels. In addition, TP and level of SOD and GSH significantly decreased compared to the control group. The pre-treatment with the combination of Ficus carica and vitamin C improved liver parameters, the level of antioxidant enzymes as well as histopathological changes. Conclusion: The combination of Ficus carica leaf extract and vitamin C had a remarkable protective action against lead acetate induced- oxidative damage in rats.

Aim: To investigate whether the aqueous extract of avocado leaves can be used in alternative medicine for the remediation or treatment of lead poisoning in the brain. Study Design: Pure Experiment, using animal models. Place and Duration of Study: Department of Anatomy, College of Medicine and Health Sciences, Abia State University, Uturu, Nigeria; between January 2019 and June 2019. Methodology: Twenty albino Wistar rats including both male and female, and weighing around 155 g were randomly assigned to four groups (designated as A,B,C and D), with each group consisting of five animals. While group A served as the control, group B was administered a daily dose of 500 mg/kg body weight of avocado leaf extract, group C received 150 mg/kg body weight per day of lead acetate, and group D was given 150 mg/kg body weight per day of lead acetate and immediately followed with 500 mg/kg body weight/day of the avocado leaf extract. Treatments were given once daily through the oral route using a syringe with attached micropipette tube for 15 days, while the animals had access to water and chow ad libitum. The rats were euthanized on the 16th day by cervical dislocation and the cranial cavity was carefully exposed in order to dissect the brain and to obtain tissue samples from the cerebellum, which were then prepared for microscopic examination using routine histological techniques, with hematoxylin and eosin (H&E) stains. Results: The findings showed the extract to be ameliorative by reducing histomorphological distortions of lead acetate toxicity in the brain, and thus caused moderate regeneration of the cerebellar tissue. Conclusion: The outcome of this research therefore indicates that the avocado leaf extract has medicinal potentials and could serve as an herbal remedy in the alternative treatment of lead poisoning.

Toxic Potential

To assess the effect of methanolic leaf extract of Caladium bicolor on the histomorphology of gastrointestinal tissues of experimental animals. Twenty four Wistar rats (weighing between 175-190 g) were randomly and equally divided into four groups which include one control group (CG) and three treatment groups (TG I, TG II and TG III). The CG was administered with distilled water [2 ml/kg body weight (b.w.)] while TGs I, II and III were administered with 100 ml/kg, 200 ml/kg and 300 ml/kg (b.w.) of C. bicolor extract respectively. All administrations were done orally and once daily for a period of thirty days. The body weight of all animals was recorded at the beginning and end of study. After the period of study, gastric and small intestinal tissues of experimental animals were harvested, processed, converted to tissue blocks and sectioned. Tissue sections were stained using Haematoxylin and Eosin (H&E) technique. Thereafter, stained sections microscopically examined for observable histopathological changes within study tissues. The results of this study showed that exposure to C. bicolor extract causes significant (p < 0.05) body weight loss in TGs I-III compared to CG. In addition, prominent histopathological changes were observed in gastrointestinal tissues of experimental animals in TGs I-III including gastric mucosal surface erosion and intestinal villi degeneration compared to normal gastrointestinal histomorphology of CG animals. These histopathological changes may be associated with toxic effect of phytochemicals constituents of the extract. Therefore, its application for therapeutic purposes needs to be thoroughly re-validated or perhaps disallowed where alternative therapeutic agents with minimal toxic potential exist.

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.

Antidiarrheal Activity

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>

This study examined the effects of increasing levels of dietary fat fed isocalorically on body weight, body composition, and adipose distribution. Adult male rats were weight matched into four groups. One group that was fed a low-fat diet (12%) served as reference controls. The other three groups were fed diets of 24, 36, or 48% fat in amounts to equal the energy intake of the control group. After 6 wk, body weights of the four groups were not significantly different. Intrascapular brown fat did not differ between groups. Total body fat and adipose depot weights, however, increased in proportion to the level of fat in the diet. Total body fat and retroperitoneal and mesenteric depot weights of the 48% fat group were greater than controls (P < 0.05). Mesenteric fat in this group was also significantly increased over all other groups (P < 0.05). These results show that high-fat diets fed to adult animals cause increased body fat in the absence of significant changes in body weight and that mesenteric fat is increased disproportionately.

An observation was made to taste the toxic effect of Vitex negundo L. and Polygonum hydropiper L. (leaf and bark) plants extracts treated fish fed group on rats, Bandicota indica. Six group of rats were fed on two different kinds of plants extracts, one is radiation dose and another untreated control group. These were, the untreated control group rats were feed on normal food such as dried fish and wheat whereas treated rats were given plant extracts and radiation dose treated by dried fish. The experimental rats were fed of 4 ml dose of plant extracts in 70% ethyl alcohol (ratio 1:10) and 4 kGy radiation treated dry fish. The toxic properties of these plant extracts were carried out the vital organs of liver, kidney, stomach, spleens, lungs and muscles on male rats .The lower mammalian species rats were used for preliminary survey their body weight gained and histopathological changes were observed. The experiment was carried out from August 2004 to December 2004. Initially the concentration of rats body weights were found as, control group (C) 43 g/m, Vitex negundo leaf treated fish fed group of rat (VL) 44.8 g/m, Vitex negundo bark treated fish fed group of rat (VB) 44.4 g/m, Polygonum hydropiper leaf treated fish fed group of rat (PL) 46.2 g/m, Polygonum hydropiper bark treated fish fed group of rat (PB) 47.8 g/m and radiation treated fish fed group of rat (R) 47 g/m. After 30 days the weight gain of rats recorded as, group (C) 324.6 g/m, (VL) 357.2 g/m, (VB) 362 g/m, (PL) 342 g/m, (PB) 323.6 g/m and (R) 352 g/m and 90 days after the body weight were group (C) 727.2 g/m, (VL) 781.2 g/m, (VB) 795.8 g/m, (PL) 780.4 g/m, (PB)764.8 g/m and R 789.8 g/m respectively. The present study is, the first attempt to use the rats body weight data found well and most suitable 4ml dose of V. negundo bark treated extracts than leaf treated group and 4 kGy radiation group. Histopathological changes of rats organs test liver was well preserved, kidney-the glomeruli, tubules, blood vessel were showed no significant changes, in the stomach-the mucosa, sub mucosa were well, in the spleen-red and white pulp were showed no significant changes, lung-the alveoli was good and in the muscle-the skeletal muscle were remain unaltered.
