ABSTRACT
There are several plant extractions which are being used for mosquito control. The aim of this study was to evaluate the efficacy of Olea vera, Linum usitatissimum and Piper nigera against Anopheles stephensi and Aedes aegypti under laboratory conditions. These tests were carried out using WHO recommended bioassay method for adult mosquitoes. The extracts from black pepper was more effective as adulticide with lowest LC[50] values [2.26% and 8.4%] against Aedes aegypti and Anopheles stephensi after 24 h of exposure while after 48h [1.56% and 5.11%] respectively. In terms of LC[90] value black pepper was best with [8.66% and 30.1%] against Ae. aegypti and An. stephensi after 24 h of exposure while after 48h [4.59% and 17.3%] respectively. In terms of LT[50] black pepper took 15 h to kill 50% tested population of Ae. aegypti while against An. stephensi it took more than 2 days. In terms of percentage mortality black pepper kill 84% of the population of Ae. aegypti and 44.75% of the An. stephensi population. Black pepper showed best results in term of LC[50], LC[90], LT[50] and percentage mortality against Ae. aegypti and An. stephensi. Our study suggested that the plant extracts have potential to kill adult mosquitoes, are environment friendly and can be used for the control of mosquitoes
ABSTRACT
Myocardial infarction is one of the most common causes of death worldwide. The cornerstone of therapy is thrombolytic therapy. Coronary thrombolysis helps restore coronary patency, preserves left ventricular function and improves survival. The most common thrombolytic agent used is streptokinase. But thrombolytic therapy is at times associated with some complications. This comparative study was aimed to find out the complications occurring during streptokinase infusion in patients presenting with acute myocardial infarction in Mayo Hospital, Lahore. Two hundred patients with definite diagnosis of acute myocardial infraction, who presented to East Medical Ward, Mayo Hospital, Lahore, were included in this study. All patients presenting with AMI were considered for SK therapy. Those who were actually given SK constituted the SK group and those who were not fit for SK, but otherwise SK was indicated, constituted the control group. In SK group 100 patients were given standard t reatment of acute myocardial infarction including streptokinase. In control group 100 patients were given standard treatment of acute myocardial infarction except streptokinase due to non-eligibility. Patients with typical chest pain of at least 30 minutes duration, serial ECG changes and serial cardiac enzyme changes were entered in the study. Comparative / interventional Post SK changes in blood pressure were significant [p= 0.011]. There was post SK hypotension in 48 [24%] and post SK hypertension in 20 [10%] patients. Allergic reaction was present in 4 [2%] only [p=0.044]. Arrhythmias were significantly less prominent in SK group [p=0.000]. Post SK bleeding occurred in 3 [1.5%] only [p=0.082]. 37 patients died [18.5%] in total, out of which 5 [2.55] patients died in SK group and 32 in control group [p=0.000]. CVA occurred in 1 SK group patient only, which was found to be hemorrhagic on CT scan [p= 0.31]. Early administration of SK lowers in-hospital mortality [p= 0.00 0]. Major complications during SK therapy are Hypotension [p= 0.011], Arrhythmias [p= 0.000], Allergic reactions [p= 0.044]
