background:   objective: the aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis.   materials and methods: in this experimental study 24 adult male nmri mice weighing 20-25gr were purchased. animals were randomly divided into 4 groups: controls, hydro-alcoholic (200 mg/kg) and aqueous extracts (50, 10...

The mature fruit of lettuce is an achene or naked seed, the color of which is determined by the color of its pericarp. The pigments that give the seed its particular color seem to be localized in the pericarp tissues.^ The mode of inheritance of seed color is of immediate practical importance to those breeding lettuce for disease resistance, climatic adaptation, and desirable commercial charact...

BACKGROUND Lactuca sativa (garden lettuce) is a popular salad herb. It has been in use in folk medicine since ancient times as both an appetite stimulant and as an aid to sleep. L. sativa seed oil (Sedan(®)) has demonstrated a pronounced sedative effect and potentiated the hypnotic effect of barbiturates in animal models. It also exhibited significant analgesic and anti-inflammatory activities....

Lactuca sativa belonging to Asteraceae family is an important leafy vegetable known for its medicinal properties. As per traditional knowledge, it is used in the treatment of insomnia, anxiety, neurosis, dry coughs, rheumatic pain, etc. [1]. The whole plant has also been used for the treatment of stomach problems, to stimulate digestion and to enhance appetite and relieve inflammation [2].The l...

Lactuca sativa, belonging to the Asteraceae family, is a leafy vegetable known for its medicinal properties. This study aimed to understand the mechanism of Lactuca sativa extract with respect to pharmacological action.We investigated the anxiolytic effects of hydro-alcoholic extract of leaves of Lactuca sativa on mice. The behavioral tests performed on mice models to assess anti-anxiety proper...

Grand Rapids lettuce seeds (Lactuca sativa L.) with 6 to 8% water content show no light-induced germination responses, whereas in seeds with 15% or more water content, germination is promoted or retarded by red and far red light respectively. By adjusting seed water content, persistent potentiated responses to light are induced in the seeds at seed water levels much below that required for germ...

In the present study, leachate toxicity of a municipal solid waste landfill located in the Sinos River Valley region (southern Brazil) was evaluated using plant bioassays. Leachate toxicity was assessed by analysis of seed germination and root elongation of lettuce (Lactuca sativa L.) and rocket plant Eruca sativa Mill.) and root elongation of onions Allium cepa L.). Bioassays were performed by...

Lettuce (Lactuca sativa L.) seeds have poor shelf life and exhibit thermoinhibition (fail to germinate) above ∼25°C. Seed priming (controlled hydration followed by drying) alleviates thermoinhibition by increasing the maximum germination temperature, but reduces lettuce seed longevity. Controlled deterioration (CD) or accelerated ageing storage conditions (i.e. elevated temperature and relative...

Lysosomal and microsomal acid phosphatase activity was estimated in midgut tissue of silkworm larvae, Bombyx mori L. (Lepidoptera: Bombycidae), after induced oxidative stress by D-galactose. The larvae were simultaneously were treated with ethanolic extracts of Bacopa monniera and Lactuca sativa to study their antioxidant properties. Lipid peroxidation and fluorescence was measured to analyze e...
