The core objective of nanoparticles is to control and manipulate biomacromolecular constructs and supramolecular assemblies that are critical to living cells in order to improve the quality of human health. By definition, these constructs and assemblies are nanoscale and include entities such as drugs, proteins, DNA/RNA, viruses, cellular lipid bilayers, cellular receptor sites and antibody variable regions critical for immunology and are involved in events of nanoscale proportions. The emergence of such nanotherapeutics/diagnostics will allow a deeper understanding of human longevity and human ills that include cancer, cardiovascular disease and genetic disorders. A technology platform that provides a wide range of synthetic nanostructures that may be controlled as a function of size, shape and surface chemistry and scale to these nanotechnical dimensions will be a critical first step in developing appropriate tools and a scientific basis for understanding nanoparticles.
To investigate the antidiabetic, antihyperlipidemic and renal protective activities of the aqueous and ethanol extract of Garcinia indica fruit rinds against alloxan induced diabetes in rats. Wistar rats were made diabetic by a single dose of alloxan hydrate [130 mg/kg i.p.]. After the successful induction of experimental diabetes, rats were divided into five groups each comprising a minimum of six rats. The effects of extracts and glibenclamide on fasting blood glucose, plasma lipid levels and renal profile were examined for 21 days. Blood glucose levels and biochemical parameters such as serum cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, urea and creatinine levels of rats were measured using on weekly intervals i.e day 0, 7, 14 and 21 after daily administration of all extracts at dose of 500 mg/kg. Statistical analysis was performed using Dunnett’s test. p less than 0.01 was taken as the criterion of significance. Oral administration of both aqueous and ethanol extract for 21 days caused a significant [p less than 0.01] reduction in blood glucose levels, lipid profile except HDL; urea and creatinine in diabetic rats. Garcinia indica fruit rind possesses antihyperglycemic activity as well improves total lipid levels and renal profile. It can justify folklore uses of the plant in diabetes.
Crigler-Najjar Syndrome (CNS) is a rare genetic condition characterized by non-hemolytic unconjugated hyperbilirubinemia. It is caused by mutations in the UGT1A1 gene which codes for the enzyme uridine diphosphate glucoronosyl transferase-1, required for the conjugation and further elimination of bilirubin from the body. Affected individuals are usually asymptomatic apart from the jaundice and investigations reveal isolated indirect hyperbilirubinemia. It can be conveniently diagnosed by evaluating the response to phenobarbital in terms of decrease in bilirubin levels. Genetic testing of the UGT1A1 gene for mutations is the investigative clincher. The hallmark outcome of Crigler-Najjar syndrome is a determined yellowing of the skin, mucous membranes and the sclera of eye. There are two patterns of this disorder: Crigler-Najjar syndrome type I, characterized by a nearly complete lack of enzyme activity and severe symptoms; and Crigler-Najjar syndrome type II, characterized by inadequate enzyme activity and milder symptoms. Both forms are inherited as autosomal recessive characters and are caused by faults or mutations of the UGT1A1 gene. Treatment is engaged toward dropping the level of unconjugated bilirubin in the blood. Early treatment is vibrant in Crigler-Najjar syndrome type I to prevent the development of encephalopathy during the first few months of life. Because Crigler-Najjar syndrome type II is milder and responds to phenobarbital, treatment is different. The purpose of the current review article is to emphasize on causes, types, clinical symptoms, autosomal pattern, complications, management and future direction for treatment of Crigler-Najjar syndrome.
A mucoadhesive drug delivery system is an oral dosage form, where the tablet, gel, or patch is attached to the buccal region for direct absorption of the drug into blood circulation. This dosage form has been employed to improve the bioavailability of drugs that undergoes significant hepatic first-pass metabolism. Acebutolol is a beta sympatholytic agent used to treat high blood pressure and irregular heartbeat (arrhythmia). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. In present investigation, mucoadhesive buccal tablets of acebutolol HCl were prepared using carbopol 940 in varying concentrations with secondary polymer xanthan gum by direct compression method. Nine batches were prepared as per 32 factorial designs, to investigate the combined effects of independent variables namely carbopol 940 and xanthan gum on dependant variables namely swelling index, mucoadhesion strength and in-vitro drug release using design expert software version 8.0.7.1. Preformulation studies confirmed the identity and purity of the drug by means of UV spectroscopy, IR spectroscopy, DSC analysis, and melting point determination. The tablets were evaluated for hardness, thickness, weight variation, friability, and drug content concluded that all these parameters were in an acceptable range of pharmacopoeial specification. The buccal tablets were studied for surface pH, swelling index, in vitro drug release study, adhesion force, in vitro mucoadhesive strength, stability, and compatibility study to optimise the formula. Amongst all factorial batches (F1 to F9), batch F5 (30 mg carbopol 940 and 30 mg xanthan gum) showed maximum drug release of 99.96 % after 12 hr of study and also showed better contact with biological membrane. The drug release kinetics of batch F5 was found to be best fitted to zero order kinetic model and exhibited anomalous diffusion release mechanism. The formulation F5 exhibited good correlation (R2=0.992) for in-vitro drug release. All the evaluation parameters give positive results and comply with the standards. Stability studies were carried out on the developed formulations indicating that the formulations were stable during the period of 6 months. In conclusion, the formulation F5 is stable and effective for quick action and seems to be alternative to the conventional tablet.
The anti-inflammatory activity of aerial roots of Ficus benghalensis was evaluated by using carrageenan induced paw oedema and cotton pellets induced granuloma in rats. The study was carried out by using 100 and 200 mg/kg doses of the aqueous extract of aerial roots of Ficus benghalensis. The preliminary pharmacological screening of the extract of aerial roots of Ficus benghalensis showed significant dose dependent anti-inflammatory profile.
