Drug utilization pattern in critical care unit in a tertiary care teaching hospital in India.

Aims: The aim of this study is to evaluate the drug utilization pattern and pharmacoeconomic analysis in critical care unit (CCU).

Materials And Methods: Indoor case papers of patients admitted in CCU between January 2008 and December 2010 were analyzed for demographic variables; indications; duration of CCU stay; proportion of common drugs used. Use of antimicrobials was evaluated based on the culture report and empirical regimen used.

Evaluation of anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits.

This study investigated the possible anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits in selected experimental animal models. Anti-inflammatory activity of Pedalium murex Linn.

Anti-urolithiatic effect of ethanolic extract of Pedalium murex linn. fruits on ethylene glycol-induced renal calculi.

Purpose: To evaluate effect of ethanolic extract of Pedalium murex Linn. fruits on experimental model of calcium oxalate nephrolithiasis.

Materials And Methods: Thirty-six male Wistar albino rats were randomly divided in 6 groups.

Toxic epidermal necrolysis due to lamotrigine in a pediatric patient.

A 12-year-male child developed toxic epidermal necrolysis (TEN) probably due to lamotrigine. The patient was on antiepileptic therapy (sodium valproate and clonazepam) since 6-7 months, and lamotrigine was added in the regimen 1-2 months back. A serious cutaneous reaction is more likely to occur during the first 2 months of starting lamotrigine.

Stavudine induced acute necrotizing pancreatitis with tetany in a pediatric patient.

A nine year old female patient presented with complaints of severe colicky abdominal pain, vomiting, and tingling with numbness for 3 days. Acute necrotizing pancreatitis associated with tetany due to anti-retroviral therapy was diagnosed. Stavudine was the probable causal agent.

Diphtheria, pertussis (whooping cough), and tetanus vaccine induced recurrent seizures and acute encephalopathy in a pediatric patient: Possibly due to pertussis fraction.

A 5-month-old male patient developed recurrent seizures and acute encephalopathy possibly due to first dose of diphtheria, pertussis (whooping cough), and tetanus (DPT) vaccine used for routine immunization. Postreaction computed tomography (CT) scan of brain, magnetic resonance imaging (MRI) of brain, and electroencephalogram were normal. Pertussis fraction of DPT vaccine is responsible for this reaction.

Effect of serum withdrawal on the contribution of L-type calcium channels (CaV1.2) to intracellular Ca2+ responses and chemotaxis in cultured human vascular smooth muscle cells.

Vascular smooth muscle cell (VSMC) chemotaxis is fundamental to atherosclerosis and intimal hyperplasia. An increase in intracellular Ca2+ [Ca2+]i is an important signal in chemotaxis, but the role of L-type calcium channels (CaV1.2) in this response in human vascular smooth muscle cells (hVSMC) has not been examined.

PDGF stimulates DNA synthesis in human vascular smooth muscle cells via a novel wortmannin-insensitive phosphatidylinositol 3-kinase.

The class 1(A) phosphatidylinositol 3-kinase enzymes consist of a number of heterodimeric complexes of regulatory and catalytic subunits and have been implicated in a number of cellular responses. While platelet-derived growth factor (PDGF)-induced chemotaxis of human vascular smooth muscle cells (HVSMC) is inhibited by both wortmannin and LY294002, DNA synthesis is only inhibited by LY294002. Serum-induced DNA synthesis however is inhibited by LY294002, wortmannin and rapamycin.

Thrombospondin-1 differentially induces chemotaxis and DNA synthesis of human venous smooth muscle cells at the receptor-binding level.

Thrombospondin-1 is a large matricellular protein that acts as a pleiotropic growth factor for human vascular smooth muscle cells, and may play a role in the progression of vascular disease. Although we have previously demonstrated the dependence of both thrombospondin-1-stimulated cell chemotaxis and proliferation on tyrosine kinases, the receptor mechanisms involved remain obscure. This investigation aims to determine the nature of the receptor(s) involved in the cellular responses to thrombospondin-1.

The antimitogenic action of the sulphated polysaccharide fucoidan differs from heparin in human vascular smooth muscle cells.

The sulphated polysaccharides fucoidan and heparin both inhibit vascular smooth muscle cell (VSMC) proliferation. In this study we compared their actions on mitogenesis and ERK1/ERK2 activation in human VSMC. Although they displaced cell surface [3H]-heparin binding with similar affinity, they exerted clearly distinguishable actions.
