The upshot of γ-irradiated Fasciola hepatica infection on the activity of plasma glutamate dehydrogenase (GLDH) and γ-glutamyl  transpeptidase (GGT) was evaluated in 36 sheep infected with a single dose of 30, 60, 120, and 240 grays and those kept as negative and positive control over 17 weeks. During this period, serum and faecal samples, as well as body weight gains, were taken at weekly intervals. Furthermore, the effects of the irradiation dose (500) for oral vaccination and on the recovery of adult flukes were assessed following primary infection. Eggs were first detected in the faeces of infected sheep on week 8 post-infection. The parasite viability was severely  affected by doses of γ-irradiation of 120 Gy or 240 Gy. In the aforementioned doses, relatively low numbers of mature flukes of about 60 (17.1%) and 38 (10.8%) were recovered than the control group, respectively. The sensitized lambs also showed less hepatic damage  compared with the controls as indicated by lower levels of the serum enzyme glutamate dehydrogenase and γ- glutamyl transferase  significant body weight loss was observed between weeks 6 and 8 post-infection followed by a steady increase of the mean weight of  infected animals across time. In conclusion, vaccination of sheep with γ irradiated metacercariae of F. hepatica appeared to affect the number and development of the fluke population resulting in reduced hepatic damage during migration, reduced fecundity after patency, as measured by worm and egg counts, levels of serum glutamate dehydrogenase and γ- glutamyl transferase.

Objective: The aim of this study was performed to evaluate Antidiabetic potentiality found in different marketed polyherbal formulation using glucocorticoid-induced hyperglycaemia in the rabbit.Methods: The potentiality of different polyherbal formulation was investigated using dexamethasone (DEX) induced hyperglycaemia in Rabbit. Eight male rabbits were divided into four groups of two each. The first group is regarded as control group received 3 ml of normal saline daily by using the gastric tube for 15 d and remaining three group received (0.35 mg/Kg B.W. single dosage) of dexamethasone tablets which were powdered, dissolved in 3 ml of normal saline daily for 15 d. After 15 d the blood glucose estimated by using a glucometer and it is found that DXE treatment leads to significant increase in levels of glucose and a significant decrease in body weight. After that second group received metformin tablet. The third and fourth group received polyherbal formulation A and formulation B, which are powdered and dissolved in 3 ml of normal saline daily for 15 d at the dose of 0.5 gm/kg body weight orally. After completion of regular administration for 15 d, the blood glucose was again estimated and compare the results of each the group.Conclusion: The Anti-diabetic polyherbal marketed formulations were having less side effect as compared to standard metformin tablet (e. g. body weight loss). And both the polyherbal formulations were found a therapeutic equivalence to each other, also having the approximately similar potentiality to standard metformin tablet.Results: The result was found that the polyherbal marketed formulations were having less side effect as compared to standard metformin tablet (e. g. body weight loss). And both the polyherbal formulations were found significantly decreased in blood glucose level at equal potentiality, which can be consider as therapeutic equivalence to each other, and both the formulation also having the approximately similar potentiality to standard metformin tablet.

The emerging and steady increase of microbes that are resistant to antimicrobial treatments has become a global public health concern that threatens the effective treatment of infectious diseases, therefore, the development of new medicines with antimicrobial properties is one of the priorities of the health systems. Cationic detergents, which, as a result of the combination of their surface activity and bactericidal properties, are promising for use in pharmacy and medicine. One of the representatives of the cationic surfactant group is polyhexamethylene guanidine hydrochloride (PGMG-GC) which was shown to be less toxic compared to some other disinfectants and effective against a wide spectrum of microbes. The aim of the study was to determine the acute toxicity parameters of a highly-dispersive silica (HDS) and PGMG-GC composite in mice after intragastric administration. The study was carried out on 23 BALB/c female mice weighing 18–22 g. To determine the toxicity, the animals were divided into the following groups. The first group was intragastrically injected with a composite of HDS and PGMG-GH, the second group was given a suspension of HDS, the third group was given a solution of PGMG-GC, and the fourth (control) group was treated with water for injection. The mass of the animals was determined before and on the 3rd, 7th, and 14th day after the composite administration. Administration of PGMG-GC or PGMG-GC + HDS composite caused significant decrease in body weight at 3rd and 7th day compared to control with further normalization on day 14. No significant changes of body weight were found in HDS group. No death of mice occurred after a single intragastric injection of the HDS + PGMG-GC composite during 14 days of the study. For the solution of PGMG-GC (without HDS), lethal cases were reported 2 h after the treatment at a dose level of 400 mg/kg. The condition of the animals survived normalized and, by the day 14, it corresponded to that in the control group for the most of the signs of toxicity indicating the reversibility of the toxic effect of PGMG-GC. Therefore, PGMG-GC is less toxic whet it is used as a part of the composite. Since no lethal cases were reported after a single intragastric administration of the composite at a dose of 2 000 mg/kg of body weight, the composite HDS + PGMG-GC appears to be low toxic according to the classification of substances by toxicity.

Animal African trypanosomiasis (AAT) also known as Nagana is a resurgent disease in Africa. Medicinal plants are being used in less developed countries for the treatment of various diseases including trypanosomiasis, due to the high cost of currently available drugs. Most of these plants have been useful sources of treatment of various diseases based on information obtained from folk medicine but have not been scientifically certified. Here, we investigated the in vitro and in vivo anti-trypanosomal potentials of the methanol extract of Aformorsia laxiflora and Khaya senegalensis against T. b. brucei. Phytochemical screening as well as LD50 of the plant extracts was carried out following standard procedures. Parasitemia was monitored daily while Packed Cell Volume was determined at three time points (days 1, 4 and 7) during the course of the infection. The phytochemical analysis showed the presence of saponins, alkaloids, flavonoids, antraquinones, resins and tanins. However, steriods/terpenoids were absent in K. senegalensis but present in A. laxiflora. The toxicity of methanol extract of both A. laxiflora and K. senegalensis was above 5000mg/kg body weight. Methanol extracts of A. laxiflora (leaves) and K. senegalensis (stem bark) showed promising trypanocidal potential in vitro against T. b. brucei at concentrations of 10, 15, 25mg/ml and 40 and 20mg/ml respectively. At these concentrations, both extracts immobilized the parasites within 55mins post-incubation. In general, A. laxiflora leaf extract demonstrated prophylactic activity against T. b. brucei in vivo at a dose of 500mg/Kg body weight particularly in group C animals where a delayed pre-patent period (6 days post-infection), extended survival (14 days post-infection) and significant (P<0.05) reduction in the parasite burden confirmed by an absence of anemia (PCV 47.00±0.8 %) was observed when compared to the infected untreated control group. K. senegalensis extract on the other hand did not show anti-trypanosomal activity in the treated groups (1, 2, and 3). Based on these observations, it was therefore deduced that the methanol extract of leaves of A. laxiflora possessed the ability to ameliorate the burden of the disease and could be a plausible candidate for drug development against the disease.Keywords: Trypanosoma brucei brucei, Afromosia laxiflora, Khaya senegalensis, anti-trypanosomal, in vitro, in vivo

Wistar Albino Rats

Leptadenia pyrotechnica (Forssk.) Decne. (LP) is used in folk medicine for the treatment of different ailments. No published studies on the affects of ground and aqueous LP extract in laboratory animals exist. Thus, this study is the first to investigate the difference between using ground or aqueous extract of LP on body weight parameters and consumptions of feed and water in young adult Wistar albino rats. Four groups (one rat of either sex for each group) were administered 25%, 50% and 75% ground LP mixed with the regular feed for 7 days, while the control rats were given the regular diet. Five groups (two rats of either sex for each group) were orally gavaged with 3, 9, 15 and 20 g LP extract/kg body weight, while the control group was gavaged with water, daily for 14 days. Findings were compared with the control groups. The mean body weight loss and feed inefficiency ratio s for the ground LP groups were higher, leading to lower feed and water intakes. Rats that consumed 15 and 20 g LP extract/kg had higher mean body weight loss and feed inefficiency ratio and lower water and feed intakes for the first but not for the second week. Therefore, both forms of LP affect weights and consumptions of water and feed during the first week. Thus, while using LP for any medicinal or therapeutic uses in humans, any affects on weight or feed and water consumptions may last only for a week.

Aqueous extract of Bambusa vulgaris L. leaves at 250 and 500 mg/kg body weight was investigated for toxic effects in pregnant rabbits. Apparently healthy, female rabbits (Dutch) weighing between 1.62 and 1.70 kg as previously used in our abortifacient study were paired overnight with male rabbits in ratio 2:1 and those that became pregnant were completely randomized into three groups (A-C). Group A (the control), received orally 1.85 mL/kg body weight (3 mL) of distilled water thrice daily on days 1-9 of pregnancy while groups B and C were treated orally with the same volume corresponding to 250 and 500 mg/kg body weight of the extract. Clinical signs of toxicity were not observed in all the animals during the study. The extract did not significantly alter (p > .05) the serum follicle stimulating hormone and total protein content of the pregnant rabbits throughout the exposure period whereas, the concentrations of luteinizing hormone, progesterone, albumin, globulin, urea and calcium decreased in the serum of the rabbits. At 250 mg/kg body weight, the extract increased kidney alkaline phosphatase (ALP) activity whereas at 500 mg/kg body weight of the extract, the ALP level was similar to the control group. Liver ALP at all doses, as well as the activity of gamma glutamyl transferase (GGT) at 500 mg/kg body weight was reduced. This reduction was accompanied by an increase in serum ALP and GGT at these doses. At 250 mg/kg, the extract increased kidney GGT. Conversely, at 500 mg/ kg, kidney GGT activity decreased. Liver and serum GGT were not altered by the 250 mg/kg. The extract also increased the serum levels of creatinine, uric acid, sodium, potassium and bicarbonate ions as well as total and conjugated bilirubin. In the hepatocytes of extract-treated animals, there was no evidence of necrosis, inflammation, fibrosis and degenerative changes in the central vein and radiating hepatic cords, while the glomerulus and the tubules of the nephrons also remained intact. The alterations in biochemical parameters by the aqueous extract of B. vulgaris leaves suggests adverse effect on the synthetic, secretory, reabsorptive and excretory functions of liver and kidney of the animals. Therefore, the absence of histopathological lesions in the hepatocytes and nephrons implies that histopathological changes are not a sensitive assay for the assessment of tissue damage by the extract.

We hypothesized that citrate might modulate the AMP-activated protein kinase/acetyl-CoA carboxylase (AMPK)/(ACC) pathway and participate in neuronal feeding control and glucose homeostasis. To address this issue, we injected citrate into the lateral ventricle of rats. Intracerebroventricular (ICV) injection of citrate diminished the phosphorylation of hypothalamic AMPK/ACC, increased the expression of anorexigenic neuropeptide (pro-opiomelanocortin and corticotropin-releasing hormone), elevated the level of malonyl-CoA in the hypothalamus, and reduced food intake. No change was observed in the concentration of blood insulin after the injection of citrate. With a euglycemic–hyperinsulinemic clamp, the glucose infusion rate was higher in the citrate group than in the control group (28.6±0.8 vs 19.3±0.2 mU/kg body weight/min respectively), and so was glucose uptake in skeletal muscle and the epididymal fat pad. Concordantly, insulin receptor (IR), IR substrate type 1 (IRS1), IRS2, and protein kinase B (AKT) phosphorylation in adipose tissue and skeletal muscle was improved by citrate ICV treatment. Moreover, the treatment with citrate for 7 days promoted body weight loss and decreased the adipose tissue. Our results suggest that citrate and glucose may serve as signals of energy and nutrient availability to hypothalamic cells.

Lactating Cows

Abstract Ketosis of lactating cows is among the most common metabolic diseases in modern dairy farms. The economic importance of the disease is caused by the reduced milk yield and body weight loss, poor feed conversion, lower conception rates, culling and increased mortality of affected animals. In the present study, a total of 47 high-yielding dairy cows up to 45 days in milk (DIM) are included. All animals were submitted to physical examination wich included checking the rectal body temperature, heart rate, respiratory and rumen contraction rates, and inspection of visible mucous coats. The body condition was scored, and blood β-hydroxybutyrate (BHBA) concentrations were assayed. The cows were divided into 3 groups: first group (control) (n=24) with blood β-hydroxybutyrate level <1.2 mmol/l, second group (n=15) with blood β-hydroxybutyrate between 1.2-2.6 mmol/l (subclinical ketosis) and third group (n=8) with blood β-hydroxybutyrate >2.6 mmol/l (clinical ketosis). Whole blood samples were obtained and analyzed for Red Blood Cell (RBC, 1012/l), Hemoglobin (HGB, g/l), Hematocrit (HCT, %), Mean Corpuscular Volume (MCV, fl), Mean Corpuscular Hemoglobin (MCH, pg), Mean Corpuscular Hemoglobin Concentration (MCHC, g/l), White Blood Cell (WBC, 109/l), Lymphocytes (LYM, 109/l), Monocytes (MON, 109/l), Granulocytes (GRA, 109/l), Red Blood Distribution Width (RDW, %), Red Blood Cell Distribution Width Absolute (RDWa, fl), Platelets (PLT, 109/l) and Mean Platelet Volume (MPV, fl). In this study, deviations in the clinical parameters in the control group and in those with subclinical ketosis were not identified. The cows from the third group (clinical ketosis) exhibited hypotonia, anorexia and body weight loss vs. control group. Hematological analysis showed leukocytosis and lymphocytosis in cows with subclinical ketosis vs. control group. In cows with clinical ketosis WBC counts decreased (leukopenia), while hemoglobin content and hematocrit values are higher vs. control group. Blood BHBA values are higher in both groups of ketotic cows vs. the control group. The other analyzed parameters (RBC, MCH, MCHC, MCV, RDW, RDWa, MON, GRA, PLT and MPV) were close to control values.

Effects of Ganoderma lucidum (Gl) and Krestin (PSK) extracts on spleen, thymus and splenocytes in γ-irradiated mice were investigated in this study. ICR strain male mice were divided into five groups. Group A was the normal control. Group B, the experimental control, was treated with Gl. Group C, the radiation treatment control, was treated with whole body exposure to 4 Gy γ-irradiation (RT). Group D was treated with RT and Gl. Group E was treated with RT and PSK. The dosage of Gl was 400 mg/day/kg body weight and PSK was 500 mg/day/kg body weight. Our results indicated that the relative thymus weight in groups D and E were higher than group C on day 28 after γ-irradiation. Group D was the highest in all the experimental groups. CD4 and CD8 splenocytes in group D were higher than group C on days 7 and 28. Gl was better than PSK in repairing the damage of subset T-cells in the spleen of γ-irradiated mice.

We investigated the effects of vitamin B1 deficiency on the meiosis maturation of oocytes. Female Crl:CD1 (ICR) mice were fed a 20% casein diet (control group) or a vitamin B1–free diet (test group). The vitamin B1 concentration in ovary was approximately 30% lower in the test group than in the control group. Oocyte meiosis was not affected by vitamin B1 deficiency when the deficiency was not accompanied by body weight loss. On the contrary, frequency of abnormal oocyte was increased by vitamin B1 deficiency when deficiency was accompanied by body weight loss (referred to as severe vitamin B1 deficiency; frequency of abnormal oocyte, 13.8% vs 43.7%, P = .0071). The frequency of abnormal oocytes was decreased by refeeding of a vitamin B1–containing diet (13.9% vs 22.9%, P = .503). These results suggest that severe vitamin B1 deficiency inhibited meiotic maturation of oocytes but did not damage immature oocytes.

Abstract The main objective of current study was to investigate the chemopreventive and chemotherapeutic activity of Artemisia vulgaris extract on diethylnitrosoamine induced hepatocarcinogenesis in Balb C mice. Diethylnitrosoamine (DEN: 0.9%) was prepared to induce hepatocarcinoma in Balb C mice. The extract Artemisia vulgaris (AV) was prepared by maceration technique. Mice were classified into four groups as follows: Group 1 a control group (N=7) received saline solution (3.5 μl/mg), group 2 (N=14) received diethylnitrosoamine (3.5 μl/mg) intraperitoneally once in a week for eight consecutive weeks, group 3 (N=7) received only plant extract (AV: 150 mg/kg (Body weight) once in a week, while group 4 (N=7) was given in combination of diethylnitrosoamine (3.5 μl/mg) and plant extract (AV: 150 mg/kg (body weight). After eight weeks of DEN administration, mice of group 2 were divided into two subgroups containing seven mice each; subgroup 1 was sacrificed while subgroup 2 was treated with plant extract only (150 mg/kg (body weight)) once in a week for eight consecutive weeks. The DEN injected mice significant decline in levels of albumin with concomitant significant elevations such as aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, alpha feto protein, gamma glutamyl transferase, 5 nucleotidase, glucose-6-phosphate dehydrogenase and bilirubin. The administration of A. vulgaris significantly decreased the DEN induced hepatotoxicity. Present study revealed the potential anti-cancerous nature of Artemisia vulgaris, both in case of chemopreventive and post-treatment of A. vulgaris. Further studies are needed to explore the mechanism of prevention and therapy.
