Use of herbal drugs in the treatment of liver diseases has a long tradition, especially in Eastern medicine. Standardization has been a problem, and randomized, placebo-controlled clinical trials to support efficacy are lacking. Some herbal extracts promoted for gastrointestinal or biliary disorders contain potent hepatotoxic alkaloids and are harmful. However, some of these extracts have yield...

A simple, precise and rapid high-performance thin-layer chromatographic method has been developed for the estimation of phyllanthin (1) and hypophyllanthin (2), the important lignans of Phyllanthus species, especially Phyllanthus amarus. Separation of 1 and 2 was carried out on silica gel 60 F254 layers eluted with hexane:acetone:ethyl acetate (74:12:8), and the analytes were visualised through...

The morphometric indices of red blood cells young fish various species inhabiting coastal zones the water bodies were studied. subjects research four families: Carp (Alburnus alburnus, Carassius gibelio, Rhodeus amarus, Abramis brama, Rutilus rutilus), Needles (Syngnathus abaster nigro lineatus), Centrarchidae (Lepomis gibbosus), Loaches (Cobitis taenia taenia), Gobies (Neogobius fluviatilis). ...

Genetic determinants of seasonal reproduction are not fully understood but may be important predictors of organism responses to climate change. We used a comparative approach to study the evolution of seasonal timing within a fish community in a natural common garden setting. We tested the hypothesis that allelic length variation in the PolyQ domain of a circadian rhythm gene, Clock1a, correspo...

Bothriocephalus acheilognathi is an introduced tapeworm in North America often reported as a serious ecological threat to native fishes. In this paper, we report the first record of B. acheilognathi in the Big Bend region of the Rio Grande in Texas (known as the Río Bravo del Norte in Mexico). Identification of B. acheilognathi was confirmed by morphologic and genetic techniques (sequences of I...

Allelopathy is a concept that applied in weed management to minimize extensively the reliance on herbicide agriculture. The allelopathic potential of Acalypha wilkesiana, Centrosema pubescens and Phyllanthus amarus Amaranthus cruentus Corchorus olitorius were investigated. Different concentrations leaf aqueous extracts A. C. P. determine their effect under laboratory conditions. profiling phyto...
