Abstract Ethnopharmacological relevanceAnemia is a very serious condition in Zambia. One of the plants that has been used traditionally is Phyllanthus muellerianus where different parts of shrub are used to treat a number of diseases in Zambian folklore medicine. Earlier studies have investigated medicinal properties of its aqueous root extracts. This study evaluated the effect of P. muellerianus roots on the hematological indices of albino rats and determined its phytochemical profile. Aim of the studyTo carry out phytochemical screening of the root extract and assess the ant-anemic effect of the aqueous extract on laboratory rats with tail-bled induced anemia Materials and MethodsThirty-six male albino rats placed in six groups were used for the study. The groups comprised the 100, 200, and 400 mg/kg plant extract, Ranferon (200 mg/kg) positive control, anemic non treated control and a normal (non-anemic) control. Anemia, induced through bleeding of the rats, was defined as hemoglobin (Hb) levels less than 12 g/dL. The anti-anemic potential of the plant was determined by comparing its effect on the hematological parameters of rats on treatment to that of the control group.ResultsAfter treatment, rats on the 400 mg/kg plant extract dose showed the greatest increase in the mean values for Hb, Packed cell volume (PCV) and RBC count were 43.3±1.2%, 15.4±0.3 g/dL and 6.3±0.3 x106 /mL respectively, when compared to the negative control group (P < 0.05). Phytochemical screening revealed positive results for alkaloids, flavonoids, saponins, glycosides, steroids, triterpenoids and tannins with varying amounts.Conclusions. The aqueous root extract of P. muellerianus was efficacious against anemia in a dose-dependent manner. The phytochemical compositions seem to be responsible for its hematopoietic properties. Thus, the root decoction of P. muellerianus is useful in alleviating anemia and the results lend credence to its use in traditional medicine in the management of anemia.

Abstract Our work aimed to evaluate the possible effect of Annona muricata (Graviola) leaf extract on Trichinella spiralis in in vitro and in vivo studies. Trichinella spiralis worms were isolated from infected mice and transferred to three culture media – group I (with no drugs), group II (contained Graviola) and group III (contained albendazole) – then they were examined using the electron microscope. In the in vivo study, mice were divided into five groups: GI (infected untreated), GII (prophylactically treated with Graviola for seven days before infection), GIII (infected and treated with Graviola), GIV (infected and treated with albendazole) and GV (infected and treated with a combination of Graviola plus albendazole in half doses). Drug effects were assessed by adults and larvae load beside the histopathological small intestinal and muscular changes. A significant reduction of adult and larval counts occurred in treated groups in comparison to the control group. Histopathologically, marked improvement in the small intestinal and muscular changes was observed in treated groups. Also, massive destruction of the cultured adults’ cuticle was detected in both drugs. This study revealed that Graviola leaves have potential activity against trichinellosis, especially in combination with albendazole, and could serve as an adjuvant to anti-trichinellosis drug therapy.

This study was carried out to ascertain the hepatotoxic potential of T.daniellii (T.d) and A. cordifolia (A.c). Investigations were conducted using standard methods. Oral administration of 200mg/kg aqueous leaf extracts of T.daniellii caused a non-significant increase in the activity of ALT (5.43±0.60IU/L), AST (16.93±0.26 IU/L) and ALP (160.70±1.04 IU/L) compared to the values recorded on the normal control (group I) ALT (3.84±0.16 IU/L), AST (14.19±0.52 IU/L) and ALP (157.26±0.64 IU/L). Group III administered with 200mg/kg methanolic leaf extract of T. daniellii manifested a significant elevation in the activity of ALT (13.15±0.89 IU/L), AST (22.84±0.38 IU/L) and ALP (170.40±0.44 IU/L) compared to the normal control. Similarly, groups IV and V which were orally administered with 200mg/kg aqueous and methanolic leaf extracts of A. cordifolia showed significant increase in the activity of ALT (6.32±0.33U/L), AST (17.70±0.030U/L) and ALP (161.13±0.09U/L) and ALT (7.55±0.59U/L), AST (19.35±0.26U/L) and ALP (165.38±0.35U/L) respectively compared to the values recorded on the control (group I). In conclusion, drug development protocols involving T. daniellii leaf should preferably use water as an ideal solvent. On the other hand, the hepatotocity associated with both aqueous and methanolic extracts of A. cordifolia could imply the presence of hepatotoxins in the leaf of the said plant.

The objective of the current investigation was performed to assess the hepatoprotective potentials and in vivo antioxidant properties of methanol extract of Tephrosia pumila against thioacetamide induced liver damage in rats. The acute oral toxicity study of methanol extract was determined as per OECD guidelines and the extract was proved to be safe up to the dose of 2000mg/kg. The total duration of the study was 21 days and animals were divided into six groups. Hepatotoxicity was induced in the animals of all groups except normal control by single dose administration of Thioacetamide(100mg/kg) at first day of the study followed by animals were treated daily with standard drug sylimarin and methanol extract of Tephrosia pumila (100mg/kg, 200mg/kg and 400mg/kg) to respective groups for 21 days. Variations in biochemical parameters like alanine transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, albumin, total protein, ions and others parameters like clotting time and weight of the liver were considered to determine beneficial effect of the extract. At the end of the study liver samples were collected and subjected to histopathological evaluation. There were significant variations in the above mentioned biochemical parameters in toxic control animals treated with Thioacetamide alone while in the animals treated with methanol extract and standard drug silymarin, all the parameters were normal possibly due to their beneficial property in protecting the liver against thioacetamide induced hepatotoxicity. The results obtained in the above study suggesting that, the methanol extract of Tephrosia pumila possess significant hepatoprotective activity.

Hepatotoxic chemicals damage liver cells primarily by producing reactive oxygen species. The decoction of the leaves ofTamarindus indicaL. is used for liver disorders. In this work we evaluated the hepatoprotective activity of a tablet formulation of this plant. Thirty-five Sprague Dawley rats were randomly divided into five groups (n=7). First group (I) is control group, fed with standard diet. Groups II to V (hepatotoxic groups) were subjected to a subcutaneous injection of CCl4(0.5 mL/kg). Group II was negative control, fed with standard diet; group III was subjected to administration of Silymarin 150 mg/kg and groups IV and V were treated with tablets in dose of 100 mg/kg and 200 mg/kg, respectively. Lipid peroxidation and the activity of superoxide dismutase, catalase, and reduced glutathione were evaluated. Serum levels of alanine aminotransferase, aspartate aminotransferase, gamma-glutamine transferase, alkaline phosphatase, and a lipid profile were evaluated too. The tablets inhibit lipid peroxidation. The redox balance (SOD-CAT-GSH) remains normal in the experimental groups treated with tablets. The liver function using dose of 200 mg/kg of tablets was better than the other experimental groups. These results justify, scientifically, the ethnobotanical use of the leaves ofTamarindus indicaL.

The purpose of this study was to investigate the effectiveness of human bone morphogenetic protein-2 (BMP-2) expressing adenoviral vector in vivo. The day before vector injection, immunosuppressant FK506 was given subcutaneously to each rat at doses of 12 mg/kg (Group I), 6 mg/kg (Group II) and 3 mg/kg (Group III). FK506 was not administered to the six rats of the control group. Twenty-five liters of AXCAOBMP-2 (3.93 × 109pfu/ml) were injected into the right calf muscle of all rats. On day 21 after vector injection, all groups were investigated radiologically, histologically, and biochemically. Osteoinduction was seen in the AxCAOBMP-2-injected groups with immunosuppression. However, no bone formation was observed in the control group. These findings suggest that AxCAOBMP-2 has the potential of osteoinduction under transient immunosuppression. AxCAOBMP-2 may be useful for future clinical application in bone reconstruction, if host immunity response can be regulated.

DespiteEuphorbia hirtaL. ethnomedicinal benefits, very few studies have described the potential toxicity. The aim of the present study was to evaluate thein vivotoxicity of methanolic extracts ofE. hirta. The acute and subchronic oral toxicity ofE. hirtawas evaluated in Sprague Dawley rats. The extract at a single dose of 5000 mg/kg did not produce treatment related signs of toxicity or mortality in any of the animals tested during the 14-day observation period. Therefore, the LD 50 of this plant was estimated to be more than 5000 mg/kg. In the repeated dose 90-day oral toxicity study, the administration of 50 mg/kg, 250 mg/kg, and 1000 mg/kg/day ofE. hirtaextract per body weight revealed no significant difference (P>0.05) in food and water consumptions, body weight change, haematological and biochemical parameters, relative organ weights, and gross findings compared to the control group. Macropathology and histopathology examinations of all organs including the liver did not reveal morphological alteration. Analyses of these results with the information of signs, behaviour, and health monitoring could lead to the conclusion that the long-term oral administration ofE. hirtaextract for 90 days does not cause sub-chronic toxicity.

Propofol is an intravenous anesthetic, reported to have a protective effect against ischemia/reperfusion (I/R) injury in heart and brain, but no definite data are available concerning its effect in hepatic I/R. This work investigated the effect of propofol anesthesia on hepatic I/R injury using in vivo rat model. Four groups of rats were included: sham operated, I/R (30 min ischemia and 2 h reperfusion), I/R treated with propofol (10 mg/kg/h), and I/R treated with propofol (20 mg/kg/h). Liver enzyme leakage, TNF-α and caspase-3 levels, and antiapoptotic Bcl-xL/apoptotic Bax gene expression, together with histopathological changes, were used to evaluate the extent of hepatic I/R injury. Compared with sham-operated group, I/R group showed significant increase in serum levels of liver enzymes (ALT, AST), TNF-α, and caspase-3 and significant decrease in the Bcl-xL/Bax ratio, associated with histopathologic damage in liver. Propofol infusion significantly attenuated these changes with reduced hepatic histopathologic lesions compared with nonpreconditioned I/R group. However, no significant differences were found between two groups treated with different doses of propofol. In conclusion, propofol infusion reduced hepatic I/R injury with decreased markers of cellular apoptosis. Therefore, propofol anesthesia may provide a useful hepatic protection during liver surgery.
