Dopp (1) demonstrated that the extract from mature prothalli of the fern species Ptcridiwtn1 aquiilinunil (L.) Kuhln hastened the onset of antheridium formation in young prothalli of this species by several days and in the prothalli of Dryopteris filixwwlas (L). Schott by several weeks. Dopp's conclusion that the prothalli of P. aquilinit elaborate a specific antheridium-inducing factor was con...

In this research, the occurrences of antimicrobial activity of some ferns were studied. The present paper dealt with the antimicrobial activities of some ethno-medicinally important ferns which were very common in West Mednapore District, as well as South West Bengal, against gram-positive and gramnegative bacterial pathogens. The plants were extracted with different solvents (70% ethanol, meth...

the water extract of trigonella foenum graecum stem and leaves was tested for lethal activity against hymenolepis nana, syphacia obvelata, and moniezia expansa. the plant extract demonstrated good anthelmintic activity in vitro which is directly related to the concentration of the extract used. the extract also prevents the formation of ascaris larvae from the eggs of ascaris lumbrico- ides (hu...

AIM An environment compatible technique to stain Platyhelminthes, Fasciola gigantica, Gastrothylax crumenifer, Taenia solium, and Moniezia expansa using aqueous and alcoholic extract of sugar beet (Beta vulgaris), China rose (Hibiscus rosa-sinensis), and red rose (Rosa hybrida) were described to minimized the deleterious effects of the synthetic dyes. MATERIALS AND METHODS Aqueous/ethanolic e...

A count was made of unhatched eggs and hatchling live and dead Podocnemis expansa turtles in 327 natural nests located on the beaches of the Environmental Protection Area (EPA) Meanders of the Araguaia River, to determine the percentage of hatching (94.63%), non-hatching (5.37%), survival (94.24%) and hatchling mortality (5.76%), and the average percentage of dead hatchlings during the 15 days ...

The rhizome of Dryopteris crassirhizoma has been used as a traditional herbal medicine for treating various inflammatory and infectious diseases such as tapeworm infestation and mumps. In the present study, we investigated the bone protective effect of water extract of the rhizome of Dryopteris crassirhizoma (WEDC). We found that WEDC inhibits osteoclast differentiation via directly acting on o...

Spore germination of five globally threatened fern species [Culcita macrocarpa C. Presl, Dryopteris aemula (Aiton) O. Kuntze, D. corleyi Fraser-Jenkins, D. guanchica Gibby and Jermy and Woodwardia radicans (L.) Sm.] was determined after 1, 6 or 12 months of storage in glass vials (dry storage) or on agar (wet storage) at -20, 5 or 20 degrees C. In all species, storage technique, storage tempera...
