Tea saponin is considered a promising natural compound for reducing enteric methane emissions in ruminants. A trial was conducted to study the effect of this plant extract fed alone or in combination with nitrate on methane emissions, total tract digestive processes, and ruminal characteristics in cattle. The experiment was conducted as a 2 × 2 factorial design with 4 ruminally cannulated nonla...

The purpose of the present study has been to determine the change in the resistance of corpuscles to saponin with changes in pII., the acids employed being the common inorganic acids. Ponder (1) has shown that the rate of saponin hemolysis is increased in the presence of certain acids and has applied the equation Cl = R (C, + g) to systems in which an acid is the accelerating agent. Details of ...

OBJECTIVE The objective of the present study was to determine whether saponin hemolysis could improve microscopic detection of malaria parasites in human blood, since it has been previously reported that the technique has been used to enrich Plasmodium falciparum culture to >or=90% parasitemia. MATERIAL AND METHODS Blood samples from suspected malaria cases were first examined in routine thic...

Intramammary infections in cattle resulting in mastitis have detrimental effects on cows' well-being, lifespan and milk production. In the host defense against S. aureus mastitis antibodies are thought to play an important role. To explore potential ways to increase antibody titers in the bovine mammary gland the effects of various adjuvants on the magnitude, isotype, and neutralizing capacity ...

Secretory proteins migrate from the rough endoplasmic reticulum (ER) to the Golgi complex at different rates. Selective retention of specific proteins to rough-ER membrane constituents could explain this phenomenon. We have permeabilized HepG2 cells with low concentrations of saponin. Release of newly synthesized proteins was studied after brief labelling in the presence of [35S]methionine. The...

BACKGROUND Malignant melanoma is a highly aggressive malignant melanocytic neoplasm which resists against the most conventional therapies. Sea cucumber as one of marine organisms contains bioactive compounds such as polysaccharide, terpenoid and other metabolites which have anti-cancer, anti-tumor, anti-inflammatory and antioxidant properties. The present study was designed to investigate the a...

The applicability of microbubble suspension made of saponin as a biodegradation-enhancing carrier where oxygen and pollutant-degraders are limited was studied. The saponin-microbubble suspension was used to deliver phenanthrene-degrading bacteria, inorganic nutrients, and oxygen. Bench-scale study was carried out to determine the physical properties of the microbubble suspension and to verify w...

Bryonia laciniosa Linn. (Cucurbitaceae) seed is used in traditional medicine for a number of ailments including metabolic disorders. This investigation was carried out to investigate the anti-hyperglycemic and anti-hyperlipidemic potential of the ethanolic extract of seeds of B. laciniosa Linn. and its saponin fraction in streptozotocin-induced diabetic rats. The ethanolic extract (250 and 500 ...

An experiment was conducted in vitro to determine whether the addition of saponin-containing Yucca schidigera or Quillaja saponaria reduces methane production without impairing ruminal fermentation or fiber digestion. A slightly lower dose of saponin was then fed to lactating dairy cows to evaluate effects on ruminal fermentation, methane production, total-tract nutrient digestibility, and milk...
