Eragrostis tremula (Burburwa) is an herbal plant native to tropical Africa, India and Myanmar. It is found in sandy soils and abandoned cultivations. It is used locally for sweeping, used as fodder for cattle and extensively being used in traditional medicine practice without assessing its safety. This study investigated the impact on blood cells (WBCs) on chronic/acute use of aqueous root extract of Eragrostis tremula among males/females wistar rats. The preliminary phytochemical screening revealed the presence of alkaloids, carbohydrate, phenols, saponins, tannins, anthraquinones, cardiac glycosides, flavonoids and diterpene. Lorke's method was used for oral acute toxicity study (LD50 determination). A total of 20 wistar rats were used, divided into four groups of five rats each. Group I was control and administered with distilled water, Group II, Group III and Group IV were respectively administered with 200 mg, 400 mg and 800 mg of the extract per kilogram body weight, for 21 days. The result of acute oral toxicity study was estimated to be greater than 5000 mg/kg. Total and differential (neutrophil, lymphocyte, and mixed cells) leukocyte counts were analysed. Eragrostis tremula aqueous root extract significantly (p<0.05) decreased lymphocyte and total leukocyte counts, but no significant changes (p>0.05) were observed in neutrophil and mixed cells count when the treated groups were compared with the control group. In conclusion, the findings of the present study have shown that, aqueous root extract of Eragrostis tremula has impact on lymphocyte and total leukocyte count in the wistar rats which is dependent on dose of the extract. The extract at high doses increases the lymphocyte and total leukocyte counts of the treated groups.

This study was performed to investigate the effects of aqueous Imperata cylindrica root extract on hepatic enzyme levels of alloxan-induced diabetic male Wistar rats. Forty (48) male wistar rats were divided into six groups consisting of eight animals each. Diabetes mellitus was induced using intraperitoneal administration 150 mg/kg body weight of alloxan and treatment was carried out for a period of 28 days. The first group served as the normal control and received only feed and water ad libitum. In Group 2 were diabetic rats without treatment with extracts. Group 3: diabetic rats treated with 200 mg/kg aqueous Imperata cylindrica root extract. Group 4: diabetic rats treated with 400mg/kg aqueous Imperata cylindrica root extract. Group 5: diabetic rats treated with 600mg/kg ethanol extract of aqueous Imperata cylindrica root extract. While Group 6 was diabetic rats treated with 0.5mg/kg Glibenclamide. The liver enzymes alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase levels were significantly (p < 0.05) changed in rats treated with Alloxan (150mg/kg b.w.) while treatment with the respective dosages of extracts significantly changed the levels of these parameters to normal. The results obtained indicate that the different doses of aqueous Imperata cylindrica root extracts were beneficial in mending damages to the liver caused by Alloxan monohydrate in the male wistar rats.

Abstract Objective Phytocannabinoids beyond the Δ9-tetrahy-drocannabinol have shown anticonvulsive effects. Also, alkylamides from Echinacea purpurea have been proved as cannabinomimetics. We examined the effect of the hydroalcoholic root extract of E. purpurea on pentylenetetrazol (PTZ)-induced tonic–clonic seizures and kindling model of epileptogenesis and the involvement of CB2 receptors as the mediator of this effect. Methods Male Wistar rats (200 ± 20 g) were used. Single intraperitoneal (i.p.) injection of PTZ (80 mg/kg) was used to induce tonic–clonic seizures. The kindling model of epileptogenesis was induced by daily injections of PTZ (37 mg/kg; i.p. for 15 days). Latency and duration of the stages were monitored for analysis. The hydroalcoholic root extract of E. purpurea was injected (i.p.) 20 min before seizure induction at the doses of 10, 50, 100 and 200 mg/kg. CB2 receptor antagonist SR144528 was injected (0.1 mg/kg; i.p.) 20 min before the Echinacea injection. Results In the tonic–clonic model, pretreatment with E. purpurea at the doses of 100 and 200 mg/kg significantly increased latencies to S2–S6, while it significantly decreased S6 duration and mortality rate. SR144528 injection before the injection of 100 mg/kg of E. purpurea significantly prevented the effects of the extract on S4–S6 latencies. In the kindling model, E. purpurea at the doses of 100 and 200 mg/kg significantly delayed epileptogenesis and decreased mortality rate, while SR144528 injection before the injection of 100 mg/kg of E. purpurea significantly blocked this effect of the extract. Conclusion These findings revealed the anticonvulsive and antiepileptogenesis effects of the E. purpurea root extract, which can be mediated by CB2 receptors.

Ayurvedic and traditional medical practitioners of Sri Lanka use the decoction of the immature inflorescence of Cocos nucifera L. (IC) variety aurantiaca for the treatment of menorrhagia. The progestogenic effect of the ethyl acetate soluble proanthocyanidins (EASPA) of the IC in female rats at a dose of 3.5 mg/kg body weight has been reported. Acute and subacute toxicity studies of EASPA of the IC carried out using female Wistar rats according to Organization for Economic Co-operation and Development (OECD) guidelines 423 and 407, respectively, are reported herein. In the acute toxicity study, a single dose of EASPA (2000 mg/kg body weight) was orally administered to rats, which were monitored for 14 days. In the subacute toxicity study, rats were orally administered with EASPA daily for 28 days at doses of 1.75, 3.5, 7, and 14 mg/kg body weight. No rat in either the acute or subacute toxicity study exhibited mortality or clinical signs of toxicity. Further, these rats did not show any significant change in their mean body weight, food, and water intake, haematological and biochemical parameters as well as in the results of their histopathological examinations compared to those of control group rats. According to results of the acute toxicity, the LD50 of EASPA is estimated to be greater than 2000 mg/kg body weight. Considering the results of the subacute toxicity study, the oral administration of EASPA daily for 28 days was well tolerated up to the dose, 14 mg/kg by rats. These results will be useful in the development of a novel therapeutic agent from EASPA of the IC for the treatment of menorrhagia, which incapacitates a considerable proportion of women worldwide.
