Medication error is a major cause of morbidity and mortality in medical profession, and anaesthesia and critical care are no exception to it. Man, medicine, machine and modus operandi are the main contributory factors to it. In this review, incidence, types, risk factors and preventive measures of the medication errors are discussed in detail.

Objective:To study the hypolipidemic activity of fresh grass juice of Triticum aestivum in normal rats.Materials and Methods:Freshly prepared Triticum aestivum grass juice was administered to normal rats at the dose of 5 ml/kg and 10 ml/kg orally once daily for 21 days. Blood samples were collected after 24 hours of last administration and used for estimation of lipid profile. Fresh grass juice was also subjected to preliminary phytochemical screening.Results:Fresh grass juice administration produced dose related significant (P < 0.05) reduction in total chloesterol, triglycerides, low density lipoprotein-cholesterol and very low density lipoprotein-cholesterol levels in normal rats as compared to control. Preliminary phytochemical screening revealed presence of alkaloids, tannins, saponins and sterols in Triticum aestivum grass.Conclusion:The results of the present study lndicate hypolipidemic activity of fresh Triticum aestivum grass juice.

Objective:To study analgesic activity and to evaluate the involvement of opioid and monoamines in the antinociceptive activity of methanol extract of leaves of Aegle marmelos.Materials and Methods:Analgesic activity of methanol extract (ME) of A. marmelos alone (75,150 and 300mg/kg orally) and in combination with morphine or venlafaxine (subanalgesic) were studied using tail flick test and acetic acid-induced writhing in mice. The effect of pre-treatment with opioid antagonist naltrexone 1mg/kg was also studied on antinociception induced due to ME.Result:ME produced a dose-dependent significant antinociceptive activity in the tail flick test and acetic acid-induced writhing in mice. (P<0.05) Administration of subanalgesic dose of ME with morphine or venlafaxine also resulted in significant (P<0.05) antinociceptive activity in both the pain models. Pre-treatment with naltrexone inhibited analgesic activity induced by ME alone and combination with morphine or venlafaxine.Conclusion:A.marmelos in induced antinociception is mediated through both opioid and monoaminergic pain pathways, suggest its possible use in chronic pain.

Background: Depressive disorder is a prevalent psychiatric disorder, which affects 21% of the world population. Many drugs which are available as effective antidepressants produce various side effects like sedation weight gain postural hypotension etc., so there is need to develop novel compounds with minimized side effects. Hence this study was aimed to investigate the antidepressant activity of DHA, an omega-3 polyunsaturated fatty acid in albino mice.Methods: Animals were divided into four groups, consisting six mice in each group. Out of these, group I served as control (2% gum acacia), group II and III received test drug in two different doses 200mg/kg and 300mg/kg respectively and group IV received fluoxetine (20mg/kg) as standard drug. To determine the antidepressant-like activity, we used forced swim test and tail suspension test in mice. These methods are based on the observation that a mouse show alternating agitation and immobility; the immobility is indicative of a state of depression.Results: DHA produced significant antidepressant effect at all the doses, as indicated by reduction in immobility times as compared to control in both FST and TST. (P˂0.05) The efficacy of DHA at dose of 300 mg/kg was comparable with that of fluoxetine. DHA at 200mg/kg dose showed significantly less antidepressant activity compared to fluoxetine. (P˂0.05).Conclusions: The result specifies that compared to two doses of DHA (200mg/kg and 300mg/kg), higher dose of DHA found as an effective dose for treating depression produced due to stress.

Objective: The main objective of this work was to study the memory-enhancing activity of docosahexaenoic acid (DHA) supplementation in normal memory function and scopolamine-induced impaired memory in mice.Methods: The gum acacia suspension of DHA was administered by gavage at the dose of 200 and 300 mg/kg in mice for 30 days to evaluate memory-enhancing potential on normal and scopolamine-induced impaired memory in albino mice. Escape latency in Morris water maze (MWM) and transfer latency (TL) in elevated plus maze (EPM) were recorded, respectively. Mice were given four trial sessions per day to locate the platform for 4 days in MWM model. Scopolamine 1 mg/kg was injected i.p. to produce memory impairment in mice.Result: DHA suspension at the dose of 300 mg/kg showed significant reduction of escape latency and TL as compared to control group, and the effect was comparable to that of standard nootropic agent piracetam at the dose of 100 mg/kg in normal and scopolamine-treated mice. However, DHA at the dose of 200 mg/kg showed significant memory-enhancing effect in only scopolamine-induced impaired memory model.Conclusion: The study revealed that the chronic administration of DHA exhibited significant memory-enhancing activity against both normal as well as scopolamine-treated impaired memory mice groups, however, this effect was more marked on scopolamine-induced memory impairment as compared to normal memory function.
