Introduction: Hepatic diseases remain the leading cause of death worldwide. Despite overall advancements in health care, mortality due to hepatic diseases is constantly growing. More than 2 million people globally are estimated to die each year from liver diseases, and current treatment offers little for its management. Thus, it is essential to find more effective and less toxic pharmaceutical alternatives for the treatment of liver diseases. Aims & Objectives: Tamarix dioica, a shrub broadly used in herbal medicine for the treatment and prevention of various diseases. The current study was designed to analyze the hepatoprotective effect of T. dioica in BALB?cmice against CCl4-induced acute liver damage. Place and duration of study: The study was conducted in NIH, Islamabad, Pakistan, for six months in 2016-2017. Material & Methods: For in vivo evaluation, the animals (n= 42) were randomly divided into seven groups (n=6), three control (i.e. Group, I or normal control, group II or induction control received 0.9% normal saline orally, and Group III or positive control received silymarin 100 mg/kg per oral), and four treatment groups (i.e. IV, V,VI and VII were treated with oral T.dioica 200 mg/kg/day, 300mg/kg/day methanol extract, 200mg/kg/day and 300mg/kg/day of aqueous extracts respectively for six days, followed by intraperitoneal administration of CCl4 on the seventh day. The blood samples were collected for analysis of LFTs, and hepatic tissue was taken for histological analysis. Data was analyzed using SPSS version 16, one-way ANOVA with Duncan’s Multiple Range Test (DMRT). Results: CCl4 induction in Group 2 resulted in severe hepatic derangement manifested as highly elevated mean LFTs (ALT 7245.56, AST 3292.11, ALP 340.09 U/L, bilirubin 4.64 mg/dl) as compared to healthy controls (ALT 38.97, AST 50.20, ALP 57.17 U/L, bilirubin 1.25 mg/dl: (Group 1) levels p<0.001. Pretreatment with different extracts of T.dioica for 6 days before CCl4 administration produced varying degrees of hepatoprotection. 300mg/kg aqueous extract T.dioica (Group7) prevented damage with maximal hepatoprotection, reduced LFTs (ALT: 339.95 , AST: 242.90 , ALP: 116.86 U/L, bilirubin: 1.38 mg/dl) and normalized liver histology as compared to Group 2 and standard drug silymarin 100mg/kg, (ALT: 6483.23, AST: 2567.69, ALP: 272.19 U/L, bilirubin: 2.84 mg/dl: Group 3) p<0.001. Lesser hepatoprotection was provided by T.dioica aqueous extract 200mg/kg (ALT: 439.93, AST: 367.87, ALP: 180.62 U/L bilirubin: 1.53 mg/dl: Group VI) and least by 300mg/kg & 200mg/kg methanolic extracts Groups V & IV (ALT: 6338.06, 6443.91, AST: 2800.81, 3012.34, ALP: 242, 248 U/L & bilirubin: 2.82 & 3.62 mg/dl) respectively. Further, no drug-induced toxicity symptoms were observed 24 hours after administration of the high dose oral T. dioica 2000 mg/kg/body weight aqueous and methanolic extracts were administered. Conclusion: Pretreatment with T. dioica extracts especially 300mg/kg aqueous extract reduced acute CCl4-mediated liver damage, ameliorated histopathological as well as biochemical parameters and was free of toxicity in 2000mg/kg /body weight dose in the mice experimental model. T. dioica has potential in hepatoprotective drug research.

Elevated cholesterol level is a major cause of disease burden in developing Nations. This study seeks to evaluate the ameliorative and hepatoprotective potentials of aqueous extract of date palm (Phoenix dactylifera) on high fat diet-induced liver damage. Thirty (30) adult wistar rats weighing 110-180g were randomly divided into six group of five animals each, group A served as control while B was exposed to high fat diet only (using margarine brand); Groups C, D and E were given high fat diet with co-treated with the extract at low, medium and high doses respectively while group F was received the drug Atrovastin as a gold standard to enable comparative effects of date palm administration. At the end of the treatment period, the animals were anaesthetized using chloroform blood samples were collected via cardiac puncture to investigate the activities of liver enzymes, and liver tissue was harvested through a midline incision for histological analysis. There were evidence of vascular congestion and periportal infiltration in rats given margarineonly indicative of hepatocellular disruption. Animals that received moderate to high dose of the fruit extract show mild to total reversal of the damaged liver cells and activation of kupffer cells with concurrent changes in serum albumin level. Aqueous extract of phoenix dactylifera was seen to ameliorate the fat induced liver damage with notable changes in hepatocyte configuration as observed when treated with standard drug.

Turmeric has been used in traditional medicine as household remedy for various diseases including biliary diseases, cough, hepatic diseases, wound healing and diarrhea etc. Curcumin is the active salt present in turmeric. This study was carried out to provide scientic basis for the use of curcumin in diarrhea and to compare it with standard medicine i.e. Loperamide. The albino rats were divided into ve groups of six animals in each group. Group I (control) received vehicular uid. Group II (positive control) received standard drug for diarrhea i.e. loperamide at the dose of 2mg/kg body weight. Group III, IVand Vwere administered curcumin intragastrically by the naso-gastric tube, in the dose of 500mg/kg, 750mg/kg and 1 gm/kg body weight respectively, suspended in normal saline. After one hour of above treatment, 1 ml of castor oil was given intragastrically to all the overnight-fasted animals to induce diarrhea. Each animal was housed separately and observed for time of onset and number of diarrheal episode for 4 hours. The data was analyzed by using SPSS 11. Remarkable anti-diarrheal effect of curcumin against castor oil induced diarrhea was observed in dose dependent manner. From the present study, we can draw a conclusion that, Curcumin have signicant anti-diarrheal effect. It may be used as an adjuvant for the treatment of diarrhea, and irritable bowel syndrome.

Objective: Evaluation of the anti-obesity effect of aqueous extract of Mucuna pruriens seeds on rats.Methods: Male Sprague-Dawley (SD) rats were subjected to high-fat diet (HFD) for 12 wk. L-DOPA (12.5 mg/kg, p. o.) as standard drug and aqueous extract of Mucuna pruriens (AEMP) seeds (200 mg/kg, p. o. and 400 mg/kg, p. o.) as test drugs were administered in last 4 wk along with HFD. Body weight, food intake, body mass index (BMI), serum total cholesterol (TC), triglyceride (TG) and high-density lipoprotein (HDL) levels were measured at the end of fourth, eighth and twelfth wk, while white adipose tissue (WAT) mass and brain dopamine levels were measured at the end of the twelfth wk.Results: AEMP (200 mg/kg, p. o.) and (400 mg/kg, p. o.) treated groups showed a significant decrease in food intake and weight gain without altering BMI. Moreover, TG levels were lower in treated groups as compared to the HFD group, but no significant changes were observed in TC and HDL levels. L-DOPA-treated group showed a significant decrease in body weight, food intake, BMI and WAT. Both AEMP and L-DOPA-treated groups showed an increase in brain dopamine levels as compared to disease control group (p<0.05).Conclusion: L-DOPA and AEMP showed anti-obesity activity by reducing body weight gains, food intake and WAT weights; modulating TG with increased brain dopamine level which correlates to the inhibitory action of dopamine on reward mechanism.

Through bite from a female Anopheles mosquito, Malaria is transmitted by infection with single-celled parasites of the genus Plasmodium. Studies have shown it to be characterized by periodic bouts of severe chills, accompanied with high fever. It has been suggested that Pennisetum purpureum possess antiplasmodial effects, however, no scientific record(s) yet exist(s) to validate this claim. This study was therefore undertaken to determine the anti-malaria and haematological properties of ethanol leaf extract of P. purpureum in Plasmodium berghei -infected mice. Thirty-Five (35) albino mice (20g) were procured, acclimatized (for two weeks) and assigned to five groups of 7 mice each. With group I receiving standard rat feed ad-libitum (control), Groups II through V were respectively infected with Plasmodium berghei (malaria infected, untreated), Plasmodium berghei infected + treated with 5mg/kg body weight of Artesunate (malaria infected, Artesunate treated), infected with Plasmodium berghei + treated with 200mg/kg body weight of Pennisetum  purpureum (malaria infected, low dose extract treated), and infected with Plasmodium berghei + treated with 400mg/kg body weight of Pennisetum  purpureum (malaria infected, high dose extract treated). After 21 days of administration, mice were sacrificed, blood samples collected, centrifuged for 10 minutes at 300g, and resulting supernatant biochemically analysed for hematologic changes. Result showed a significant increase in initial parasite count across groups except control. Administration of Artesunate also caused a significant (p < .05) reduction in parasite counts upon comparison with control. More so, administration of low and high dose extract caused a significant (p < .05) reduction in parasite count following comparison with control. Administration of 200mg/kg caused the highest parasitemia suppression than high dose. We recommend for further evaluation of the plant in other to identify active ingredients responsible for the observed antimalarial activity.

Objective: This study aims to assess the effects of the aqueous extract of Hydrocotyle javanica (HJ) in ameliorating mercury-induced neurobehavioral toxicity.Methods: For the study, 36 adult male Swiss albino mice of 25–30 g in weight were taken. They were equally divided into six groups. Group I was treated with distilled water, Group II was treated with mercuric chloride (1.5 mg/kg), Group III was treated with HJ extract low dose (100 mg/kg), Group IV was treated with HJ extract high dose (200 mg/kg), Group V was treated with mercuric chloride plus HJ extract low dose, and Group VI was treated with mercuric chloride plus TB extract high dose. In all the groups, the doses were administered orally through oral gavage tube and the treatment lasted for 14 days. The behavioral effects evaluated were locomotor activity in the open field test, immobility in forced swimming test and anxiety in elevated plus maze test, spatial learning ability, and memory in the Morris water maze test.Results: The present study showed that mercury exposure significantly decreased the locomotor activity (p<0.001), number of annulus crossovers (p<0.001), number of open arm entries (p<0.01), time spent in open arms (p<0.001), and increased escape latency (p<0.01), path length (p<0.001), and immobility (p<0.001) in mice. The aqueous extract of HJ significantly alleviated the neurotoxic effects of mercury. The aqueous extract of HJ showed to increase the locomotor activity (p<0.01), number of annulus crossovers (p<0.001), number of open arm entries (p<0.05), and time spent in open arms (p<0.05), which was decreased in mercury-exposed mice. The HJ extract also showed to decrease the immobility (p<0.001), escape latency (p<0.05), and path length (p<0.001) in mercury-exposed mice.Conclusion: The result of the study shows that neurobehavioral changes induced by mercuric chloride were significantly reversed by the aqueous extract of HJ. Thus, base on the present study, it is concluded that HJ is effective in ameliorating the neurobehavioral deficits induced by mercury.

 Objective: The current study was designed to estimate the potential protective role of the aqueous extract of rosemary (AER) (Rosmarinus officinalis) against trichloroacetic acid (TCA)-created hepatotoxicity in male albino rats.Methods: Forty male albino rats were separated into four groups of ten: Group I served as control; Group II was given AER (200 mg/kg/day) by gavage; Group III received TCA at the dose 50 mg/kg/day, and Group V was treated with AER (200 mg/kg/day) and received TCA (50 mg/kg/day). The experiment was carried out for 2 months.Results: The toxicity of TCA for rats was revealed by an elevation in liver marker enzymes activities (gamma-glutamyl transferase [GGT], alkaline phosphatase [ALP], aspartate transaminase [AST], alanine aminotransferase [ALT]) and conjugated bilirubin (CB) level, and a decrease in albumin and total protein (TP) levels. The TCA administration also caused a significant increase in the activities of catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD), and also malondialdehyde (MDA) level in liver tissues. These biochemical effects were accompanied by histological indicators of liver damage. Treatment with ARE recovered the liver damage instigated by TCA, as showed by perfection of liver enzyme markers (GGT, ALT, AST, ALP), CB, TP and albumin; as well as antioxidant parameters (CAT, SOD, GPx) and lipid peroxidation (MDA) and amelioration of histopathology changes in the liver tissues.Conclusion: It could be concluded that AER supplementation for 2 months in TCA-induced toxicity in rats benefited hepatic antioxidant status and improved liver injury and damage in male albino rats exposed to TCA.

AbstractBackgroundL. (BV), commonly known as “MethodsSixty IOPS mice were divided into six groups and were treated as follows: group 1 (normal control) received double distilled water; group 2 (toxic control) received lead acetate (5 mg/kg body weight/day) in double distilled water for 40 days; groups 3–6 received BV aqueous extract at doses of 25, 50, 100 and 150 mg/kg body weight , respectively, once daily for 30 days from 11 day after beginning of lead acetate exposure to the end of the experiment.ResultsToxic control group showed a significant alteration of serum alanine-aminotransferase (ALT), aspartate-aminotransferase (AST), total cholesterol (TC), total bilirubin (TB), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) and reduced glutathione (GSH). Histological assessment of lead-intoxicated mice liver revealed alterations in hepatocytes and focal necrosis. BV treatment significantly prevented lead accumulation, increased ALT, AST, TC, and TB, inhibited lipid peroxidation and protein carbonyls(PCO) formation. Additionally, BV extract normalized the antioxidant enzymes (CAT, SOD and GPx), GSH and architecture of liver tissues.ConclusionsBV aqueous extract exerts significant hepatoprotective effects against lead-induced oxidative stress and liver dysfunction. The BV effect may be mediated through the enhancement of antioxidant status, lead-chelating abilities and free radicals quenching.

Abstract Pregnancy and feto-gestational toxicities on exposure to fluoride (F) and its possible amelioration on co-administration with Aloe-vera were studied in pregnant Swiss albino mice. Once the confirmed pregnancy was tested, animals were equally divided into four groups and were given following treatment. Group I was given no treatment and served as Control, Group II and III were administered sodium fluoride, 100 and 300 ppm respectively while group IV was co-administered with sodium fluoride, 300 ppm and Aloe-vera (300mg/kg) daily for 14 days prior to gestation and continued till the 18th day of gestation. Animals were sacrificed `on the 19th day of gestation for prenatal observations. Maternal body weight, the gravid uterine weight, number of corpora lutea in both the ovaries, number of implantations and resorptions, number of live (mature and immature ) male and female fetuses as well as number of dead fetuses were examined in each dam. The treatment continued in another set of animals till the completion of weaning period to observe postnatal changes due to test substances on the mother and pups. Sodium fluoride treated animals showed morphometric and skeletal changes which were more pronounced in the high dose group showing significantly decreased body weight gain in pregnant mothers; and dead/immature fetuses. Morphometric changes included open eyelids, limb defects, wrinkles on whole body, anophthalmias, pulmonary edema, enlarged esophagus and decreased body weight of fetuses and pups. Alizarin prepared skeletal structures of fetuses of such female mice showed delayed ossification or bending in number of bones of skull, thoracic and limb regions. However, concomitant exposure to Sodium Fluoride and Aloe-vera treated animals, there was a marked improvement in all the prenatal and postnatal variables. The study suggests that Sodium fluoride at the high concentrations may be teratogenic while co-administration of Aloe-vera during fluoride exposure might be beneficial in reducing these toxic effects. We thus recommend use of aloe vera as preventive agent or as a complimentary agent during fluoride treatment.
