Cardiotonic and vasoconstriction effects of aqueous methanolic extract of Paspalidium flavidum L.

The cardiovascular activity of aqueous methanolic extract of Paspalidium flavidum L. was evaluated on isolated rabbit heart and aorta. Heart rates, force of contraction and perfusion pressure were assessed in the presence of different concentrations of extract and adrenaline by using Langendorff's technique. Moreover, the vasoconstriction effects were studied in rabbit aorta using isolated organ bath. The results indicated that the extract [1ng-100[micro]g/ml] exhibited a significant increase in heart rate, contractility and perfusion pressure of isolated rabbit's heart; with a maximum effect at 1ng/ml, which was comparable to adrenaline [1[micro]g/ml]. Similarly, adrenaline at doses from 1-10[micro]g/ml produced a significant dose dependant increase in all the cardiac parameters. The cardiotonic effects of the extract were significantly blocked by propranolol [10[-5]M] while an increase in perfusion pressure was completely antagonized by verapamil [10[-6]M]. Activity of cardiac marker enzymes was also significantly raised in the perfusate of isolated heart pretreated with the extract. In rabbit aorta, the extract exhibited a dose dependent vasoconstriction effect however it did not increase the tone of aorta when pre-treated with verapamil [10[-6]M]. It is conceivable therefore; that the cardiotonic and vasoconstriction effects of the extract might be due to its agonistic actions on beta-receptors and Ca[+2] channels

Diabetes mellitus modifying factors; investigation among the inhabitants of Sargodha city, Pakistan

Diabetes mellitus is wide spread non transmissible disease but its prevalence is increasing everyday so this study was conducted with an aim to investigate the factors that are modifying diabetes mellitus among patients at DHQ [District Head Quarter] Hospital Sargodha. A prospective study was carried out by well-trained pharmacists in DHQ Sargodha, Pakistan to assess the factors modifying diabetes mellitus. Data was collected from 110 patients randomly by using convenience sampling method. A well structured questionnaire was designed to collect information from patients and entire procedure was conducted with the permission of concerned authorities of Hospital management. The factors that are considered in present study are medication, treatment, patient physician interaction and society attitude towards diabetic patients which are helpful in halting the progression of diabetes and prevention of co morbidities. The results of study disclose that 74.5% diabetic patients felt better after treatment whereas 56% diabetic patients were satisfied with the information provided by physician to them but still 70% patients were suffering from co morbidities. The survey indicated that 62.7% patients said that exercise proved to be healthy activity in improving diabetes. However 59% diabetic patients were following a proper diet plan which was helpful in modifying their diabetes. The diabetic patients must be informed about importance of regular follow-up in averting long-standing complications. Patients should be guided about importance of dietary recommendations, exercise and strict metabolic control, that can holdup or avert the series of complications allied with diabetes
