Evaluation Of The Diuretic Activity Of Boerhaavia Verticillata

The present investigation was undertaken to evaluate the potential diuretic activity of Boerhaavia verticillata . The ethanolic and aqueous extracts of B. verticillata were administered in doses of 50 and 100 mg/kg, i.p., to normal and adult albino rats, which were monitored over a period of 24 h. Experimental results confirmed that both the ethanol and aqueous extracts have diuretic properties, but the ethanol extract seems to have less diuretic and natriuretic activity than the aqueous extract.     

Assessment of Genetic Fidelity Using Random Amplified Polymorphic DNA and Inter Simple Sequence Repeats Markers of <Emphasis Type="Italic">Lawsonia inermis</Emphasis> L. Plants Regenerated by Axillary Shoot Proliferation

An efficient, reliable and reproducible plant regeneration protocol was developed for Lawsonia inermis L. using mature nodal explants. Shoot proliferation (81.6 %) with 7.8 shoots/explant was achieved on Murashige and Skoog’s (MS) medium supplemented with 1.0 mg l^?1 6-benzyladenine. Shoot numbers were up-scaled by inducing multiple shoots from axenic nodal segments derived from the primary shoots on the shoot regeneration medium. Thus the authors could achieve ca. 129–134 shoots from single nodal explant. Ninety-three percent rooting of in vitro regenerated shoots was achieved on growth regulator free half-strength MS medium. Regenerated plantlets were successfully transferred to soil with 85 % survival rate. Genetic stability analyses of the in vitro regenerated plants using random amplified polymorphic DNA and inter simple sequence repeat markers revealed a homogeneous amplification profile for all micropropagated plants. This is the first report that evaluates the use of molecular markers to establish genetic fidelity of micropropagated L. inermis for the rapid clonal multiplication and true-to-type production of plant for attaining the ever increasing demand in pharmaceutical industries.     

Pilot Study Comparing Systemic and Tissue Pharmacokinetics of Irinotecan and Metabolites after Hepatic Drug-Eluting Chemoembolization

Differences in drug metabolism associated with UGT1A1 polymorphism could result in individualized local response to hepatic chemoembolization with irinotecan-eluting beads (DEBIRI) or predictable toxicities. Five patients with inoperable hepatic metastases from colorectal or anal malignancies treated with DEBIRI were assessed for UGT1A1 mutations. No difference in area under the curve (AUC) for SN38 in normal liver and tumor tissue samples was noted with variant or wild-type UBT1A1 (P = .16 and P = .05, respectively). Plasma SN-38 AUC was significantly lower in wild-type compared to variant patients (P < .0001). UGT1A1 genotype may not be predictive of hematologic toxicity after DEBIRI.     

Pancreatic ascites and Pleural Effusion in Children: Clinical Profile,Management and Outcomes

BackgroundPancreatic ascites (PA) and pleural effusion (PPE) are rarely encountered in children. They develop due to disruption of the pancreatic duct (PD) or leakage from an associated pancreatic fluid collection (PFC). The literature on childhood PA/PPE and its management is scarce.MethodsA retrospective review of children with PA/PPE diagnosed and managed at our center over the last 4 years was performed. The clinical, biochemical, radiological and management profiles were analyzed. Conservative management included nil per oral, octreotide and drainage using either percutaneous catheter or repeated paracentesis. Endotherapy included endoscopic retrograde cholangiopancreatography (ERCP) and transpapillary stenting.ResultsOf the 214 children with pancreatitis, 15 (7%) had PA/PPE. Median age was 9 years with a third under 2 years. Median ascitic fluid amylase was 8840 U/L and all had elevated protein (>2.5 g/dl) and low serum ascites-albumin gradient ascites (<1.1). While PA/PPE was the first manifestation of underlying chronic pancreatitis (CP) in 10 children (67%), trauma was seen in 4 (26%) and hypertriglyceridemia in 1 (7%). On imaging, PD disruption could be identified in 10 (67%) children. ERCP and stenting was done in 10 children. Conservative management alone (n = 4) and endotherapy (n = 10) was successful in 93% with only one requiring surgery. The younger children (n = 4), were managed conservatively and only 1 of them required surgery. Resolution of PA/PPE was achieved in all with no recurrences.ConclusionsConservative management and ERCP plus transpapillary stenting results in resolution of majority of pediatric PA/PPE. Children presenting with PA/PPE needs to be evaluated for CP.     

Image fusion and navigation platforms for percutaneous image-guided interventions

Image-guided interventional procedures, particularly image guided biopsy and ablation, serve an important role in the care of the oncology patient. The need for tumor genomic and proteomic profiling, early tumor response assessment and confirmation of early recurrence are common scenarios that may necessitate successful biopsies of targets, including those that are small, anatomically unfavorable or inconspicuous. As image-guided ablation is increasingly incorporated into interventional oncology practice, similar obstacles are posed for the ablation of technically challenging tumor targets. Navigation tools, including image fusion and device tracking, can enable abdominal interventionalists to more accurately target challenging biopsy and ablation targets. Image fusion technologies enable multimodality fusion and real-time co-displays of US, CT, MRI, and PET/CT data, with navigational technologies including electromagnetic tracking, robotic, cone beam CT, optical, and laser guidance of interventional devices. Image fusion and navigational platform technology is reviewed in this article, including the results of studies implementing their use for interventional procedures. Pre-clinical and clinical experiences to date suggest these technologies have the potential to reduce procedure risk, time, and radiation dose to both the patient and the operator, with a valuable role to play for complex image-guided interventions.     

The role of radiation therapy in the management of sarcomas

Sarcomas represent a heterogeneous, challenging, and rare group of tumors that present many management challenges. In this article, the authors concentrate on the radiotherapeutic management of sarcomas occurring in the most common locations: the extremities, the trunk, and the retroperitoneum. An overview of the current radiotherapeutic management of soft tissue sarcoma is presented in addition to a discussion of how surgical management may affect radiotherapeutic management. Finally, the authors describe current controversies surrounding the appropriate management of sarcomas with radiotherapy and describe ongoing studies and future areas of research.     

Serum magnesium: an early predictor of course and complications of diabetes mellitus

The aim of this study was to evaluate relationship between serum magnesium and course of diabetes mellitus and also to find out, if there is any relation between serum magnesium and various complications of diabetes mellitus. A cross-sectional study was conducted to examine the relationship between serum magnesium in 50 type 1 and type 2 diabetic patients with or without complications and 40 normal healthy persons. Serum magneisum estimation was done using calmagite dye method using autoanalyser (Beckman DU clin systems). Serum magnesium levels in diabetic population was significantly low (1.93 +/- 0.282 meq/l) in comparison to control (2.25 +/- 0.429 meq/l). It was statistically significant (+3.84; p < 0.005). Serum magnesium was significantly low in diabetes with complication than without complications (p < 0.001). Duration of diabetes and serum magnesium were inversely related. Poor glycaemic control was associated with hypomagnesaemia (-2.623; p < 0.05). There was strong association between hypomagnesaemia and retinopathy (1.76 +/- 0.26), obesity (1.878 +/- 0.326) and hypertension (1.75 +/- 0.071) and it was statistically significantly (p < 0.005, 0.042, 0.000 respectively). Hence it is concluded that the change in serum magnesium level may have a bearing on the complication and morbidity in patients of diabetes mellitus.
