Background: The mulberry tree, a plant of the family Moraceae and the genus Morus, has been widely cultivated to feed silkworms. Various parts of Morus alba linn used as an Anti-inflammatory, hypoglycemic, cardioprotective, hepatoprotective, free radical scavenging activity and neuroprotective agent. The plant contains flavonoids, moranoline, albanol, morusin coumarine, and stilbene, which have. In this study, anticonvulsant property of Morus alba leaves extract (MAE) was evaluated by using MES and PTZ induced convulsion in rats.Methods: Effects of MAE were evaluated in experimental models of electro convulsions, maximal electro shock (MES) and chemoconvulsion induced by pentylenetetrazole (PTZ) in rats (n=6), which were treated intraperitonially with doses of 100, 200 and 400mg/kg.Results: The duration of tonic hind limb extension (seconds) with MAE in MES induced convulsions at dose of 100, 200, 400 mg/kg is 8.33±1.21, 6.83±1.16 & 3.16±0.98 respectively. In the dose of 400 mg/kg of MAE showed highly significant results by reducing the duration of tonic hind limb extension in MES induced convulsions. And onset of jerky movements (seconds) with MAE in PTZ induced convulsions at dose of 100, 200, 400mg/kg is 157.83±8.99, 195.66±17.02 and 295.50±21.10 respectively. In the dose of 400mg/kg of MAE showed highly significant results by delaying the onset of convulsions.Conclusions: Results indicate that the MAE have anticonvulsant effects in MES induced convulsions and in PTZ induced convulsions.
Presently, treatment of anxiety with standard anti-anxiety drugs is associated with a number of shortcomings inviting us to study newer agents that would overcome these problems or search for the drugs or substances, which would enhance the efficacy or reduce the dose or toxicity of this standard anti-anxiety drug diazepam. Ganaxolone (GNX) a positive allosteric modulator of GABA A receptors, may represent a new treatment approach for anxiety. The present study was undertaken to evaluate the antianxiety effect of ganaxolone in comparison with diazepam and also to study their effect on sleep and motor coordination using elevated plus maze, thiopentone sodium induced sleeping and rotarod model in rodents. Wistar strain albino rats weighing 200-250 gm were used. Ganaxolone produced significant anti-anxiety effect compared to control group but the activity was less when compared to diazepam. The sedative and muscle relaxant properties of ganaxolone were weak as compared to diazepam. Ganaxolone had significant synergistic effect with diazepam by potentiating its actions, thereby providing a lead for exploring potential benefit of adding ganaxolone to decrease the dose of diazepam in the treatment of anxiety.
Background: Impetigo is a contagious bacterial skin infection that affects both adults and children. Topical antibacterials such as mupirocin and fusidic acid are the most commonly used in both primary and secondary impetigo. Clinical trials have shown high efficacy of retapamulin in the treatment of secondary impetigo. However, its use in primary impetigo is limited. To this purpose, we compared the safety, efficacy and adherence to treatment of fusidic acid with retapamulin in primary impetigo.Methods: A total of 50 patients with a clinical diagnosis of primary impetigo, between 2-12 years of age, having <10 lesions, 3/5 signs and symptoms, skin infection rating score ≥4 and pus score ≥ one were involved. Patients who were having secondary impetigo leions were excluded. Twenty-five patients received 2% fusidic acid cream three times a day, and the remaining 25 patients received 1% retapamulin ointment two times a day for seven days. Skin Infection Rating Scale (SIRS) was used to assess the severity of disease at baseline and end of treatment. Clinical success was considered when SIRS score of zero each for pus, crust and pain and 0/1 each for erythema and itching. Clinical failure is a SIRS score of ≥1 for pus.Results: Baseline disease characteristics such as a number of lesions, the severity of disease (SIRS) and pus scores were statistically similar between the two groups. The clinical improvement observed with both fusidic acid and Retapamulin (20/25, 80%) and (21/25, 84%) treatments was not statistically different (p>0.05). Both drugs were well tolerated.Conclusions: Both fusidic and retapamulin showed similar clinical success in patients with primary impetigo. Since fusidic acid has anti-inflammatory property and its treatment is cost-effective, it can be considered as first-line treatment and retapamulin in fusidic acid-resistant impetigo.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
