Objective. To improve the existing experimental model of croton oil-induced hemorrhoids in rats by using Evans Blue (EB) dye extravasation technique. Further, an herbal formulation (Pilex) was evaluated for its antihemorrhoidal activity in this model. Methods. Two sets of experiments were carried out: first to improve the experimental model and to validate the same using Pilex and second to eva...

BACKGROUND Croton lobatus contains a high amount of antioxidant phytochemicals that probably account for its wide use as food and medicine in the traditional communities of West Africa. METHODS The study evaluated the modulatory role of methanol extract of Croton lobatus leaf on alloxan-induced diabetes and associated cardiovascular complications. Male rats were randomly selected and assigned...

Toll-like receptor (TLR) ligands are being developed for use as vaccine adjuvants and as immunomodulators because of their ability to stimulate innate and adaptive immune responses. Flagellin, a TLR5 ligand, was reported to show potent mucosal vaccine adjuvant activity. To identify ligands that potentiate the adjuvant activity of flagellin, we screened a plant library using HEK293T cells transi...

Methanol leaf extracts of two Ethiopian traditional medicinal plants viz., Lomisar [vernacular name (local native language, Amharic); Cymbopogon citratus (DC) Stapf. (Poaceae)] and Bisana [vernacular name (local native language, Amharic); Croton macrostachyus Del. (Euphorbiaceae)] were screened for larvicidal activity against late third instar larvae of Anopheles arabiensis Patton, a potent mal...

The root extract and fractions of Croton zambesicus were investigated for anticancer activity against HeLa cells, DNA interaction, immunomodulatory and antileishmanial activities. The GCMS analysis of the most active fraction against HeLa cell was carried. The root extract was found to exert significant anticancer activity with the hexane fraction exhibiting the most pronounced effect. The crud...

Four furanoditerpenoids were isolated from roots of Croton jatrophoides (Euphorbiaceae) collected in Tanzania. In addition to the known compounds penduliflaworosin and teucvin (mallotucin A), a new teucvin isomer, which was named isoteucvin, and a furanoditerpenoid with a new skeleton, for which the name jatrophoidin was adopted, were isolated. Their structures were elucidated by spectroscopic ...

brought to visible tumors. Mottram (10) observed tumor production in mouse skin after exposing it to a single treatment with a carcinogenic hydrocarbon, followed by re peated applications of croton oil. Later, Berenblum and Shubik (3) adapted this method to a quantitative approach to the study of chemical carcinogenesis. According to this method, the actual number of tumors produced were said t...

The inhibition of tumor incidence by hydro-alcoholic extract of the whole plant of P. urinaria was evaluated in 6-7 weeks old female albino mice on two-stage process of skin carcinogenesis induced by a single application of 7,12-dimethylbenz(a)anthracene (50 microg/50 microl of acetone), and 2 weeks later, promoted by repeated application of croton oil (1% in acetone/three times a week) till th...
