EFFECT OF PITHECELLOBIUM DULCE BENTH LEAVES IN DEXAMETHASONE INDUCED DIABETIC RATS

Objective: The objective of the present study was to study the effect of Pithecellobium dulce Benth (P. dulce) leaves in dexamethasone-induced diabetic rats.Methods: The authenticated P. dulce leaves were collected from a local area of Sangli, Maharashtra. The leaves of the plant were extracted with water and ethanol by maceration and soxhelation respectively. Acute toxicity studies of the both extracts were performed using rat and according to OECD 425 guidelines. The dose of 200 mg/kg and 400 mg/kg was selected for further studies. The albino rats were divided into seven groups with five animals in each group. The diabetes was induced by dexamethasone (10 mg/kg, s. c.) and treated with extract and standard drug for 10 d. Then blood glucose, triglyceride, total cholesterol and glycogen level in liver, muscle and kidney were estimated according to standard procedures.Results: The study revealed that P. dulce at 200 mg/kg and 400 mg/kg showed significant (p Ë‚ 0.05) antidiabetic activity. All the extract treated groups showed a significant reduction in blood glucose level on 11th day when compared to diabetic control group. The significant increase in blood glucose, triglyceride, and total cholesterol level was observed in the diabetic control group when compared to normal control group. The liver and muscle glycogen level was decreased significantly (p Ë‚ 0.05) in the diabetic control group.Conclusion: It can be concluded that P. dulceaqueous and ethanolic extract at two different doses (200 mg/kg and 400 mg/kg) possesses antidiabetic and hypolipidemic activity.Â

Improved functionalization of oleic acid-coated iron oxide nanoparticles for biomedical applications

Superparamagnetic iron oxide nanoparticles can providemultiple benefits for biomedical applications in aqueous environments such asmagnetic separation or magnetic resonance imaging. To increase the colloidal stability and allow subsequent reactions, the introduction of hydrophilic functional groups onto the particles’ surface is essential. During this process, the original coating is exchanged by preferably covalently bonded ligands such as trialkoxysilanes. The duration of the silane exchange reaction, which commonly takes more than 24 h, is an important drawback for this approach. In this paper, we present a novel method, which introduces ultrasonication as an energy source to dramatically accelerate this process, resulting in high-quality waterdispersible nanoparticles around 10 nmin size. To prove the generic character, different functional groups were introduced on the surface including polyethylene glycol chains, carboxylic acid, amine, and thiol groups. Their colloidal stability in various aqueous buffer solutions as well as human plasma and serum was investigated to allow implementation in biomedical and sensing applications.status: publishe

ABSTRACT Vitex negundo Linn. is a large aromatic shrub distributed throughout India. Herbal medicine, rather than merely curing a particular disease, aims at returning the body back to its natural state of health. It has been used since ancient times as a female remedy and also for pains in Ayurveda and also in Roman medicine. It became known as the chaste berry tree. This species is globally distributed in Indo-Malesia, cultivated in America, Europe, Asia and West Indies. Within India, it is found throughout the greater part of India, in the outer Himalayas. Myriad medicinal properties have been ascribed to Vitex negundo Linn. and the plant has also been extensively used in treatment of a plethora of ailments as traditional medicine, folk medicine and pharmacological evidence. Traditionally the leaves of Vitex negundo Linn. are documented to possess antibacterial, antitumor, astringent, febrifuge, sedative, tonic and vermifuge. It has been reported to posses potent pharmacological properties like anti-inflammatory, anti-rheumatic, antibiotic, Hepatoprotective, antioxidant, anticonvulsant, oxidative stress, anti-androgen, snake venom neutralization and anti-allergic activities. The various chemical constituents like flavonoids, flavones glycosides, volatile oil, triterpenes, tannins and many others were identified in this plant. This review gives a bird's eye view mainly on the pharmacognistic characteristics. traditional uses, phytochemistry and pharmacological actions of Vitex negundo Linn

Language development, hearing loss, and intracranial hypertension in children with TWIST1-confirmed Saethre-Chotzen syndrome

Saethre-Chotzen syndrome (SCS) is an autosomal dominant condition defined by mutations affecting the TWIST1 gene on chromosome 7p21.1. Previous research has identified an elevated prevalence of intracranial hypertension and hearing impairment associated with this syndrome. This study aimed to investigate the influence of hearing history and presence of intracranial hypertension on language development in children with SCS. A retrospective study note analysis was performed for all patients with a confirmed TWIST1 gene abnormality who attended the Oxford Craniofacial Unit and underwent a language assessment over a 22-year period. Intracranial pressure monitoring, hearing status, and language outcomes were examined in detail. Thirty patients with genetically confirmed SCS and language assessment data were identified. Twenty-eight patients underwent surgical intervention; 10 presented with intracranial hypertension (5 prior to, and 5 after primary surgical intervention). Language data coinciding with the presentation of intracranial hypertension were available for 8 children. About 44% of children with intracranial hypertension presented with concurrent receptive and expressive language delay (n = 4/8). For both children (n = 2) with longitudinal language data available, the onset of intracranial hypertension reflected a concurrent decline in language skills. Audiometric data were available for 25 children, 80% (n = 20/25) had a history of hearing loss. About 50% of these had confirmed conductive hearing loss with middle ear effusion and the other 50% had presumed conductive hearing loss with middle ear effusion. About 100% of the children with available hearing data in our study had evidence of middle ear effusion in at least 1 ear. Results also indicated that 43% (n = 13/30) of the children presented with receptive and/or expressive language delay during childhood. Given the importance of hearing for language development and the preliminary findings of a potential decline in language skills in children during periods of intracranial hypertension, regular follow-up of hearing, language, and intracranial hypertension are indicated in children with SCS.</p

Priapism – A Rare Presentation in Chronic Myeloid Leukemia: Case Report

Priapism is a complication rarely seen in leukemia. We report a 19-year-old man presented with persistent painful erection of penis for over 24 hours at home. The patient had underwent immediate irrigation and decompression of priapism by urologist at emergency services of the hospital. This approach resulted in a flaccid penis later. During hospitalization, peripheral blood smear and bone marrow aspiration confirmed the diagnosis of chronic myeloid leukemia
