Effect of yogic practices on selected physiological variables among hypertensive middle-aged women

The purpose of the random group experimental study was to investigate the effect of Yogic Practices on selected Physiological variables such as Systolic, Diastolic and Body Mass Index (BMI) among Hypertensive middle aged women. It was hypothesized that there would be a significant difference due to Yogic Practices on selected Physiological variables such as Systolic, Diastolic and Body Mass Index (BMI) among Hypertensive middle-aged women than the control group. Random group experimental design was used. The random sampling design was followed to select the subjects. To achieve the purpose of the study, 30 women between the age 45 and 55 years were selected randomly from Chennai and they were divided into two groups such as Yogic Practices (Group A) and Control Group (Group B). Each group consists of 15 subjects. The pre-test was taken for the two Groups on the selected dependent variables before the start of the training program. Group A was undergoing Yogic Practices for 12weeks, 6 days a week, One-hour maximum daily and Group B (Control Group) was permitted to undergo their normal lifestyle (active rest) during the course of the experiment. After the experimental period of 12 weeks, Post-tests were conducted for the two groups on selected dependent variables. The selected Physiological variables such as Systolic, Diastolic and Body Mass Index (BMI) were measured through Lab test. Analysis of Co-Variance (ANCOVA) was used to find out the significant difference between experimental group and the Control Group. The test of significance was fixed at 0.05 level of confidence. It was concluded that Yogic Practices improved Physiological variables among Hypertensive middle-aged women than the Control Group. Hence, the hypothesis was accepted at 0.05 level of confidence

Emerging horizons in anaesthetic practice: a pharmacological update

Anesthesiologists are in search for new drugs possessing properties like rapid onset of action, minimal residual effects, better hemodynamic stability, organ independent metabolism and cost effective. Structural alterations of the currently available compounds or newer formulations of the older ones or newer anaesthetic drug delivery system will be an useful alternative to newer discovery by reducing the cost and time. Tapentadol is a centrally acting µ opioid receptor (MOR) agonist with selective norepinephrine reuptake inhibition, approved by US FDA for treating moderate to severe acute pain in adults more than 18 years of age. Sugammadex, a novel selective relaxant binding agent to reverse steroidal neuromuscular blockers is recently approved by the European Union. Gantacurium, a rapid and ultra short acting non depolarizing neuromuscular blocker, inactivated rapidly by the adduction of non essential amino acid cysteine to the gantacurium molecule is in clinical trials. Remimazolam is a new drug in clinical trials that has a rapid onset of action like midazolam and is metabolized by non specific tissue esterases like remifentanil and expected to have a promising future. Liposomal Bupivacaine is approved by FDA in October 2011 that uses bupivacaine in liposomal vesicles to extend the duration of analgesia upto 72 hours and reduces the opioid use in the post operative period. Methoxy carbonyl carboetomidate is in clinical trials that combines the advantages of MOC etomidate and carboetomidate. Hence anaesthesiology is marching towards a bright pathway with new soft drugs coming up making not only anaesthesiology soft but also pharmacology

PREPARATION AND CHARACTERIZATION OF CEFTRIAXONE SODIUM ENCAPSULATED CHITOSAN NANOPARTICLES

Objective: The objective of this study was to prepare ceftriaxone sodium chitosan nanoparticles (CS-NP) from different drug and polymer ratios and analyze their physicochemical characteristics.Methods: Ceftriaxone sodium loaded chitosan nanoparticles were prepared using chitosan as a polymer and tri sodium polyphosphate (TPP) as cross linking agent by ionic cross linking and coacervation with the aid of sonication. Various trials have been carried out for the confirmation of nanoformulation. Parameters such as the zeta potential, polydispersity, particle size, entrapment efficiency, in vitro drug release Thermo gravimetric analysis and scanning electron microscope of the nanoparticles were assessed for confirmation of nanoformulation.Results: The formulated nanoparticles showed mean particle size, polydispersity index and zeta potential to be 183.1±8.42 nm, 0.212±0.05, +38.5±1.6 mV respectively and the drug loading was found to be 46.42±10 %. In vitro drug release was showed a biphasic release pattern with initial burst release followed by sustained release of formulated nanoparticles. The cumulative percentage of drug release was about 83.08 %.Conclusion: Formulation F2 was found to be the best formulation with a higher cumulative percentage of drug release. Modified ionic gelation method can be utilized for the development of chitosan nanoparticles of ceftriaxone sodium. Polymer and crosslinking agent concentrations and sonication time are rate-limiting factors for the development of the optimized formulation. The chitosan nanoparticles developed would be capable of sustained delivery of ceftriaxone sodium

Hepatoprotective and antioxidant activity of Murraya Koenigii leaves extract against paracetamol induced hepatotoxicity in Rats

Background: Many pharmacological substances are known to cause hepatic injuries and paracetamol is one out of them. This study was carried out to investigate the hepatoprotective and antioxidant activity of hydroalcoholic extract of Murraya koenigii leaves in paracetamol induced hepatotoxicity in Rats.Methods: Experimental animal used in this study were 30 healthy male albino Wistar rats of 10 to 12 wks weighing 180 ± 20 g. After acclimatization for a period of one week, the rats were randomized into five groups of six rats each. Safety profile and dose selection of extract was evaluated using acute toxicity studies. Five groups named as Normal control, Paracetamol induced hepatotoxicity, Murraya koenigii leaves extract 100 mg/kg bw, Murraya koenigii leaves extract 200 mg/kg bw and Silymarin group respectively. The doses of drugs and plant extract was calculated based on the body weight of each animal and administered orally for 7 days. On 8th day rats were sacrificed and blood samples were collected by cardiac puncture for biochemical estimation of biochemical parameters. Then abdomen was opened to get liver sample for antioxidant activity and histopathology.Results: Acute toxicity studies showed the non-toxic nature of Murraya koenigii leaves extract upto dose of 2000 mg/kg body weight. Murraya koenigii leaves extract in both doses showed a significant drop in the mean levels of AST, ALT, ALP, TP and TB when compared with toxic control group. The higher dose was found better than lower dose. Silymarin was found better than both the doses. Murraya koenigii leaves extract in both doses significantly reduced the TBARS level when compared to toxic control group. The activities of GSH, SOD and CAT in liver were significantly lower in Paracetamol induced hepatotoxicity rats compared to control rats. Murraya koenigii leaves extract at both doses showed a significant increase in GSH, SOD and CAT. The higher dose was found better than lower dose. Silymarin was found better than both the doses. Histopathology of Liver biopsy with higher dose of Murraya koenigii leaves extract showed reduced periportal inflammation with mild hepatic venous congestion and Silymarin treated rats showed no periportal inflammation with mild congestion in few central veins.Conclusions: Murraya koenigii leaves extract possesses significant Hepatoprotective property; this may be due to antioxidant activity. Further studies are required to determine the exact mechanism
