Aim: The study investigated the antidiarrheal potential of methanol extract of Combretum dolichopetalum and its solvent fractions. Method: Leaves of Combretum dolichopetalum were extracted using methanol as solvent. This was classified as the crude methanol extract (MECD). The crude extract was further fractionated using column chromatographic techniques to get various fractions. Castor oil was used to induce diarrhea in the animals, following atropine and the plant extracts to confirm any antidiarrheal activity. Fecal excretion and absorption/secretion ratio, enteropooling, small intestinal transit, glucose estimation, free fatty acid estimation and fecal osmolarity were employed to serve as antidiarrheal biomarker. Result: result showed improvements in all studied biomarkers compared to the negative control. The extract worked similarly like the standard drug used atropine. Conclusion: From the result of this study, it can be concluded that the methanol extract of Combretum dolichopetalum and it fractions contains compounds with antidiarrheal potentials, and this justifies it use in ethnomedicine.

Crude Methanol Extract

Brassica rapa subsp. chinensis (L.) Hanelt is a popular herb in Bangladesh. In the present studies, the plant has been assessed to evaluate its in vitro thrombolytic and membrane stabilizing properties. Initially, the plant was collected, processed and extracted with methanol and the concentrated crude methanol extract was fractionated into petroleum ether, carbon tetrachloride, chloroform and aqueous soluble materials. All extractives, including the parent extract were subjected to thrombolytic and membrane stabilizing bioassays. In case of thrombolytic study, the carbon tetrachloride soluble fraction exhibited highest clot lysis. Here, streptokinase and distilled water were used as positive and negative control, respectively. However, in the assay for membrane stabilizing activity, the crude methanol extract along with other extractives were capable to inhibit hemolysis of erythrocyte membrane in hypotonic solution- and heat- induced conditions, which indicated anti-inflammatory property of the samples. Acetyl salicylic acid was used as standard drug in this assay. This represents the first report of thrombolytic and membrane stabilizing activities of B. rapa subsp. chinensis.

Objectives: The use of natural products is embraced by a larger percentage of the world population. Most species of fungi including mushrooms produce useful secondary metabolites that stimulate the immune system against infection and diseases. Investigations were conducted to assay the therapeutic potentials of P. ostreatus against pathogenic staph infection.Methods: The methanol extract of P. ostreatus was prepared using the cold extraction method. Thirty Wistar albino rats weighing 82.0 g to 99.2 g were distributed into 6 groups of 5 and inoculated orally with actively growing Staphylococcus aureus suspension. P. ostreatus methanol extract LD > 5000 mg/kg 50 was used to determine the graded doses for the study. Graded doses of the extract 625 mg, 1250 mg, and 2500 mg were administered orally to the experimental animals for seven days.Results: The negative control and 625 mg had skin ulceration while 1250 mg to 2500 mg produced apparently healthy skin. Bacterial count after 7 days post-treatment was significantly high in the negative control and 625 mg dose (32.00 x 104 ± 6.10b; 43.40 x 104 ± 6.20b Cfu/ml) P< 0.05. Haematological and serum biochemical values were not significantly P < 0.05 affected. Pleurotus ostreatus administration at 1250 to 2500 mg produced a statistically low colony count that was comparable with 13.33 mg Ciprofloxacin and placebo.Conclusion: Pleurotus ostreatus at 1250 to 2500 mg was able to produce clinical recovery from S. aureus infection while 625 mg could not. The extract had no deleterious effect on the blood parameters, liver enzymes, and kidney biomarkers.

Lipid lowering effect of polyherbal formulations using eight different plants was evaluated in triton and diet induced hyperlipidemic models of wistar albino rats. Formulations such as Tablet, Syrup and Suspension inhibited the elevation in serum cholesterol and triglyceride levels on Triton WR 1339 administration rats. The formulations at the same dose level significantly attenuated the elevated serum total cholesterol and triglycerides with an increase in high-density lipoprotein cholesterol in high-fat diet-induced hyperlipidemic rats. The standard drug Niacin showed slightly better effects. The treatment with herbal formulations produced 30-35 percentage improvement in oral glucose tolerance. Similarly all the formulations also reduced the elevated C-reactive protein which is a marker of Hyperlipidemia. In histopathological study it was found that treatment of polyherbal formulation significantly reduced the plaque size in aorta compared with HFD treated control group. The outcome of the study reveals the lipid lowering activity of polyherbal formulations in dyslipidaemic conditions by interfering with the biosynthesis of cholesterol and utilization of lipids.

Background and Aim: Many natural products worldwide are used for medicinal purposes. Various insect-isolated compounds were investigated in pursuit of new therapeutic agents. This study aimed to compare the effects of methanol extract of hemolymph of Sarcophaga argyrostoma larvae with diminazene aceturate on some hematological and biochemical indices of mice infected with Trypanosoma evansi. Materials and Methods: Sixteen albino mice were randomly divided into four groups, of four mice, which received different treatments: In Group 1 (G1), mice were infected intraperitoneally with 1×104 T. evansi and received no treatment (positive control), in Group 2 (G2), infected mice were treated with 0.5 mL/kg of diminazene aceturate, in Group 3 (G3), infected mice were treated with 0.5 mL/kg methanol extract of the hemolymph of S. argyrostoma larvae, and in Group 4 (G4), uninfected mice received 0.5 ml of distilled water (negative control). In G3, treatment was started 3 days before injecting the parasite, while for the other groups, a single dose of treatment was applied when the parasite appeared in the blood. Results: Mice from G3 showed low parasitemia of 29×104/mm3 4 days post-infection until the infection completely disappeared on the 5th day, which was earlier than for other groups. The results showed that the numbers of red blood corpuscles (red blood cells [RBCs]) and white blood cells (WBCs) per unit volume were significantly different (p<0.05) between the four groups. The highest RBC (9.09×103 cell/ mm3) and WBC (14.30×103 cell/ mm3) counts were recorded in G3, whereas the lowest values of 6.60 and 4.60×103cell/ mm3, respectively, were recorded for G2. In addition, there were significant differences (p<0.05) between the different groups for platelet counts per unit volume, with G3 having the most (943×103 cell/ mm3) and G2 having the least (357×103 cell/ mm3). There was a significant (p<0.05) difference in the indices of biochemical activities between the extract-treated infected groups and the standard drug-treated group. Conclusion: This study suggests that the methanol extract of the hemolymph of S. argyrostoma larva exhibits trypanocidal activity, so it may be exploited as a suitable candidate for the development of trypanocidal drugs.

Sonchus arvensis L. leaves have been used traditionally to treat various disease conditions. This study is designed to evaluate cardioprotective potential of ethanol extract of S. arvensis leaves on isoproterenol-induced myocardial infarction in Wistar rat. Male Wistar albino rats were divided into three main groups: negative control (saline only), positive control (isoproterenol only), and S. arvensis extract treated groups. S. arvensis extract was administered in three doses; 50, 100, and 200 mg/kg b.w. p.o for 14 days. On day 13 and 14, isoproterenol (85 mg/kg bw) was given intraperitoneally to positive control and extract treated groups. The parameters studied were cardiac biomarker enzymes which were Creatine Kinase (CK), Creatine Kinase-MB (CK-MB), Aspartate Transaminase (AST), Alanine Transaminase (ALT) and Lactate Dehydrogenase (LDH). The results showed that S. arvensis at dose of 50 mg/kg b.w. could significantly (P<0.05) reduce the level of CK, CK-MB, AST, ALT, and LDH in myocardial infarcted rats compared to positive control. The increase of the dose of S. arvensis extract was not followed by an increase of its cardioprotective activity. In conclusion, Sonchus arvensis L. leaves extract at dose of 50 mg/kg b.w. has potential to be developed as cardioprotective drug.
