Flavonoid fractions of diosmin and hesperidin mitigate lead acetate-induced biochemical, oxidative stress, and histopathological alterations in Wistar rats.

This study aims at investigating the protective effects of flavonoid fractions of diosmin and hesperidin in mitigating sub-chronic lead acetate-induced biochemical, oxidative stress, and histopathological alterations in adult male Wistar rats. Forty animals were randomly assigned into five groups, each consisting of eight animals. Group I animals was treated with deionised water only, group II, IV, and V were administered lead acetate 90 mg/Kg body weight (1/20th of the LD), groups III, and IV was administered Daflon (100 mg/Kg), while group V was administered Daflon (200 mg/Kg), 30 min prior treatment with lead acetate.

Protective effect of fisetin against subchronic chlorpyrifos-induced toxicity on oxidative stress biomarkers and neurobehavioral parameters in adult male albino mice.

Chlorpyrifos (CPF), a chlorinated organophosphate insecticide that is widely used in agriculture and public health, has neurotoxic effects in animals. In addition to acetylcholinesterase inhibition, CPF has been shown to induce alterations such as oxidative stress and lipid peroxidation. Fisetin is a dietary flavonol that protects the brain tissue against oxidative stress by modulating the activity of antioxidant enzymes.

Evaluation of phytochemical constituents and sedative-hypnotic activity of the methanol leaf extract of in mice.

Background And Aim: Sedative drugs mostly cause dose-dependent depression of the central nervous system which results in hypnosis and anesthesia possibly; however, these agents are associated with some side effects ranging respiratory, digestive, immune system dysfunctions, tolerance, cognitive function deterioration, and physical dependence; hence, investigations of newer and safer agents are, therefore, imperative. The current study was aimed at investigating the sedative-hypnotic (S-H) effects of the methanol leaf extract of in mice.

Materials And Methods: Phytochemical screening of the leaf extract was conducted, and S-H activity of the plant extract was evaluated.

Anaemogenic, Obesogenic and Thermogenic Potentials of Graded Doses of Monosodium Glutamate Sub-acutely Fed to Experimental Wistar Rats.

Background: Monosodium Glutamate (MSG) is one of the most commonly used food additives for the enhancement of food taste and flavour. There are several conflicting reports of toxicity or otherwise safety of the compound, which raises a growing concern regarding the safety of monosodium glutamate as a food additive.

Objective: In the present study, we sought to investigate the effect of monosodium glutamate on body weight, feed consumption, body temperature and some haematological parameters.

Local Anaesthetic Effect of Methanolic Leaves Extract of Lannea schimperi (Hoschst. Ex Rich) Eng.

Background: Local anaesthetics provide relief from pain when applied locally to nerve tissue by blocking conduction of sensory nerve impulse from the receptor to the brain cortex.

Objective: This study aimed at evaluating local anaesthetic activity of the methanolic leaves extract of Lannea schimperi.

Methods: Six groups of five animals were used; groups I-IV were used for intracutaneous wheal test in guinea pigs for infiltration anaesthesia, while group V and VI were used for guinea pig corneal reflex method of surface anaesthesia.

Phytochemistry, Antinociceptive and Anti-inflammatory Actvities of Methanolic Leaves Extract of Lannea schimperi (Hoschst. Ex Rich) ENG.

Background: Pain whether acute or chronic, peripheral or central is believed to originate from inflammation and inflammatory response. The potential toxicity of antinociceptive and antiinflammatory agents such as non steroidal anti-inflammatory drugs (NSAIDs) necessitates sourcing for less toxic alternative drugs. Many natural substances have been used for the management of pain and inflammation with success traditionally.

Forced swim test: What about females?

In preclinical studies screening for novel antidepressants, male and female animals should be used. However, in a widely used antidepressant test, the forced swim test (FST), sex differences between males and females are not consistent. These discrepancies may discourage the inclusion of females in FST studies.

New alkylresorcinols from a lipophilic extract of Urginea indica L. bulbs showing experimental trauma healing activity.

Several alkylresorcinols presenting the substitution pattern of structures I (3-methyl ether of 5-alkyl-2-methylresorcinol) and II (1,3-dimethyl ether of 5-alkylresorcinol), were isolated from the dichloromethane extract of the air-dried bulbs of Urginea indica L. Compounds of structure I with 15, 17 and 20 carbon atoms in the alkyl chain as well as compounds of structure II with 20, 22, 24 carbon atoms in the alkyl chain are new. The structures of the new compounds were elucidated on the basis of their NMR and MS data.

Sertraline behavioral response associates closer and dose-dependently with cortical rather than hippocampal serotonergic activity in the rat forced swim stress.

The rat Forced Swim Test (FST) is widely used to investigate the response to antidepressant treatment. Selective serotonin reuptake inhibitors (SSRIs) elongate swimming duration during the FST, while climbing duration is unaffected. In the present study, we aimed to correlate behavioral effects of the SSRI sertraline in the FST with respective changes in the serotonergic activity of the hippocampus and the prefrontal cortex.

Behavioral sexual dimorphism in models of anxiety and depression due to changes in HPA axis activity.

Anxiety and depression are considered as stress-related disorders, which present considerable sex differentiation. In animal models of anxiety and depression sex differences have been described and linked to the sexually dimorphic hypothalamus-pituitary-adrenals (HPA) axis. The present study aimed to adjust corticosterone, the main HPA axis stress hormone, in male and female adrenalectomized rats with oral (25 μg/ml) corticosterone replacement (ADXR).

Individual differences in novelty-seeking predict differential responses to chronic antidepressant treatment through sex- and phenotype-dependent neurochemical signatures.

Women experience major depression at roughly twice the rate of men. Inconclusive clinical evidences assist the notion that responsiveness to antidepressant pharmacotherapy is sexually dimorphic with the two sexes presenting differential responses when treated with tricyclic antidepressants (TCAs). Notably, responsiveness to antidepressive agents presents marked inter-individual variability, the biological basis of which remains elusive.
