Seasonal occurrence of such wound-induced reaction in birch foliage which deteriorates the quality of nearby leaves for herbivores was tested by means of bioassays. Length of the larval period was protracted in two early and mid-summer (larval period!) lepidopteran species as well as in two
Retinal ganglion cell (RGC) death is part of many retinal diseases. Here, we report that the ethanol extract of Diospyros kaki (EEDK) exhibits protective properties against retinal degeneration, both in vitro and in vivo. Upon exposure to cytotoxic compounds, RGC-5 cells showed approximately 40%
This paper examines physiological characteristics of the leaves of Agastachys odorata R.Br., a wet-climate sclerophyllous shrub with very long-lived leaves. It addresses the hypothesis that cuticles become leakier to water vapour as leaves age. Astomatous cuticular conductance, whole-leaf minimum
Effects of seawater spray on leaf structure were investigated in Quercus acutissima by electron microscopy and X-ray microanalysis. Two-year-old seedlings of Q. acutissima were sprayed with seawater and kept in a greenhouse maintained at 25°C. The most recognizable symptoms of seawater-sprayed
BACKGROUND
Use of antioxidants is a means of reducing rancidity of fats and oils in food stuffs. The commercial synthetic antioxidants in food industry have been suspected to cause negative health effects. Therefore as alternatives, there is a strong need in finding new effective and safe
The effects produced by the administration of aqueous suspensions of the green or dried leaves of Azadirachta indica, a common tropical plant, were investigated in goats and guinea pigs. At doses of 50 or 200 mg/kg given orally over a period of up to eight weeks, the plant produced a progressive
Oral administration of hydroalcoholic extract of A. indica (250 and 500 mg/kg) effectively inhibited CCl4 and paracetamol induced changes in the serum marker enzymes, cholesterol, serum protein and albumin in a dose-dependent manner as compared to the normal and the standard drug silymarin-treated
BACKGROUND
In the East Asia, the genus Acer (Aceraceae) is a herbal medicine that is used to treat various diseases, including hemostasis, hepatic disorders, traumatic bleeding and poor eyesight. However, the effects of Acer palmatum thumb. on retinal degeneration are unknown.
OBJECTIVE
In this
Haematological, biochemical and pathological effects in rats produced by the salt-tolerant plant Avicennia marina given at oral doses of 1 or 4 g kg(-1) for three consecutive days or 0.5 g kg(-1) day(-1) for 28 consecutive days are reported. No overt behavioral changes, moribundity or mortality were
OBJECTIVE
Chilling tolerance of salicylic acid (SA) in banana seedlings (Musa acuminata cv., Williams 8818) was investigated by changes in ultrastructure in this study.
METHODS
Light and electron microscope observation.
RESULTS
Pretreatment with 0.5 mmol/L SA under normal growth conditions (30/22
The purpose of the study was to investigate the protective effects of the ethanol extract of Diospyros kaki (EEDK) persimmon leaves to study N-methyl-N-nitrosourea (MNU)-induced retinal degeneration in mice. EEDK was orally administered after MNU injection. Retinal layer thicknesses were
This study investigated the toxic effects of dried pulverized Caloncoba echinata leaves on the hematology, blood biochemistry and vital organs of male albino rats. Twenty adult male rats were randomly divided into four groups of five rats each. Groups A, B and C were fed 25.00%, 15.00% and
