The effect of the gene dosage on the expression of rRNAs was studied in Hypericum perforatum. The methylation levels of rDNA were analysed using the isoschizomers MspI and HpaII and eleven additional methylation-sensitive enzymes. No differences in rDNA methylation were observed between diploids and tetraploids at an early ontogenetic stage.
This experiment was conducted to determine if nigrostriatal dopamine (DA) neurons are necessary for the contraversive rotational behavior evoked by electrical stimulation in the lateral hypothalamus. Rats were tested daily for electrical stimulation-induced rotational behavior (ESRB) for 5 days, and then given an injection of 6-hydroxydopamine (6-OHDA) or saline into the ipsilateral substantia ...
Introduction: A variety of maladies, sometimes disabling, beset many ovulatory women in a recurrent manner during the luteal phase of each ovarian cycle. These problems can deteriorate interpersonal relationships and/or interfere with normal activities of life. Present research was performed to evaluate effects of hypericum perforatum for treatment of physical symptoms of premenstrual syndrome....
OBJECTIVE Hypericum perforatum (St. John's Wort) has long been used in traditional medicine to treat a variety of internal and external ailments. The present study was done to evaluate the immumodulatory potentials of the hydroalcoholic extract of H. perforatum. MATERIALS AND METHODS Twenty male BALB/c-mice were randomly allocated in two equal groups and immunized with sheep red blood cells (...
Theaflavins, the oxidation products of tea polyphenols are important biologically active components of black tea. 6-hydroxydopamine is a pro-parkinsonian neurotoxin. Theaflavins could inhibit the auto-oxidation of 6-hydroxydopamine in a dose-dependent manner from 0.5 µg/ml to 25 µg/ml. Here we investigated the protective effect of theaflavins on 6-hydroxydopamine induced SH-SY5Y cells against a...
T-lymphocytes have been previously implicated in protecting dopaminergic neurons in the substantianigra from induced cell death. However, the role of T-cells in neurodegenerative models such as Parkinson's disease (PD) has not been fully elucidated. To examine the role of T-lymphocytes on motor behavior in the 6-hydroxydopamine (6-OHDA) unilateral striatal partial lesion PD rat model, we assess...
St. John's wort (Hypericum perforatum) is an herbal remedy used widely for the treatment of depression. Recent clinical studies demonstrate that hypericum extracts increase the metabolism of various drugs, including combined oral contraceptives, cyclosporin, and indinavir. In this report, we show that hyperforin, a constituent of St. John's wort with antidepressant activity, is a potent ligand ...
Introduction: Episiotomy is the most common surgical incision during vaginal delivery. Recently herbal medicine is being considered in episiotomy healing. Considering the analgesic effects of Hypericum Perforatum, this study is performed to investigate the effect of Hypericum Perforatum ointment on episiotomy wound pain. Methods: This study was a double-blind randomized clinical trial, perfo...
The purpose of this study was to investigate the effects of treatment with water, n-butanol and ether extracts of Hypercom perforatum L. on epileptogenesis in rabbits. Animals from the control group received solvent-ethanol, and the kindling model of epilepsy was used. Epileptic focus was induced in Chinchilla rabbits by stimulation of the hippocampus. The following parameters were determined: ...
BACKGROUND A stressful stimulus is a crucial determinant of health and disease. Antidepressants are used to manage stress and their related effects. The present study was designed to investigate the effect of St. John's Wort (Hypericum perforatum) in restraint stress-induced behavioral and biochemical alterations in mice. METHODS Animals were immobilized for a period of 6 hr. St. John's Wort ...
