Effects of the novel herbal medicine, KIOM-C, on the growth performance and immune status of porcine circovirus associated disease (PCVAD) affected pigs
This experiment was conducted to investigate the effects of the administration of a novel herbal medicine formula, KIOM-C, as a growth promoter and immunostimulator in pigs suffering from porcine circovirus associated disease (PCVAD). A single-dose oral toxicity test and genotoxicological tests (including bacterial reversion assay, in vivo micronucleus test, and in vitro mammalian chromosomal...

Optimization of extraction efficiency of tannins from Cichorium intybus L.: Application of response surface methodology
The effect of solvent concentration and time on the extraction efficiency of tannins from root, stem, leaves, and seeds of Cichorium intybus L. was studied. A 22-factorial central composite design was employed by using response surface methodology to optimize the extraction conditions. The analysis of variance showed the significant effect of both variables on the extraction yield of tannins. The lower...

Microwave- assisted Hydrodistillation of Essential Oils from Echinophora platyloba DC
Microwave-assisted hydro distillation (MAHD) protocol, applied optimal extraction condition (650 W, 35 min) was used to extract an essential oil from the aerial part of Echinophora platylabo DC, which was collected from the Binaloud Mountain- Nishapor city. To evaluate the effect of microwave energy on the yield and composition of essential oil, MAHD method results were compared to those obtained by...

Effects of solvent type on phenolics and flavonoids content and antioxidant activities in Onosma dichroanthum Boiss.
In our research, 8 kinds of solvents extracts from roots of Onosma dichroanthum Boiss. were used to examine the effects of extraction solvent on total phenolics (TP), total flavonoids (TF) , total anthocyanin (TA) content and antioxidant activity by 1,1-diphenyl-2-picryl hydrazyl radical scavenging (DPPH), total antioxidant capacity (TAC), reducing power (RP) and antioxidant activity (AA)...

The impact of traditional methods of managing snake bite in humans and livestock among the Hausa-Fulani communities of Sokoto State (North-western Nigeria)
raditional snake bite healers, farmers and Fulani cattle rearers in some local government areas of Sokoto State were interviewed through the use of structured questionnaires for the various ways they manage snake bite in their livestock. Almost all of them use plants either for prophylaxis, treatment or as repellants. Prophylactic treatment is only practiced in humans, while first aid treatment and post-treat mental...

Inhibitory effect of essential oil from Agastache rugosa against nitric oxide (NO) production induced by inducible nitric oxide synthase (iNOS) over-expression through NF-κB and mitogen-activated protein kinase (MAPK) activation in lipopolysaccharide (LPS)-stimulated RAW264.7 cells
In this study, the anti-inflammatory effect of the essential oil from Agastache rugosa (EOA) in RAW264.7 cells was evaluated. The effect of EOA on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 cells was examined. EOA inhibited NO over-production, which was accompanied by the down-regulation of inducible nitric oxide synthase (iNOS) expression, as evaluated by western blot. To...

Isolation and chemotaxonomic significance of megastigmane-type sesquiterpenoids from Sarcandra glabra
In this study, twelve known compounds including six megastigmane-type sesquiterpenoids, two coumarins and four phenols were isolated for the first time from Sarcandra glabra(Thunb.) Nakai, a traditional medicinal plant with a variety of pharmaceutical activities. Their structures were determined using nuclear magnetic resonance (NMR) and mass spectrometry (MS) techniques and the chemotaxonomic significance of...
