In this paper we have presented a novel design of miniaturized microstrip antenna used for wireless applications. The antenna is based on reconfigurability property, consisting of one switch which is used to change the surface current distribution and hence the frequency of operation. Antenna in ON state have dual band at 3.5GHz and 5.8GHz, while antenna in(More)
This double-blind, randomised, within patient, placebo-controlled study set out to investigate the effect of a cardioselective beta-blocker, atenolol, at different oral doses (50, 100 and 200 mg) and a non-selective agent, propranolol (40 mg), upon 1. airways resistance (forced expiratory volume at one second=FEV1) and 2. the bronchodilator action of(More)
Twenty patients suffering from angina pectoris with co-existing fixed or labile airways obstruction, were administered fortnightly treatment periods of nifedipine or matching placebo over an 8-week period. Maintenance treatment for their airways obstruction continued throughout this period. Nifedipine was found to be an effective drug in controlling their(More)
Ten patients with allergic perennial rhinitis completed a 3-month course of reatment with flunisolide nasal spray. Biopsy of the nasal mucosa was carried out before the initiation of treatment and at the end of the treatment period. The flunisolilde was administered as a 0.025% solution twice daily at a total daily dose of 200 micrograms. No histological(More)
A three-month controlled study was performed to assess the cumulative incidence of oral Candida carriage and thrush in patients starting to take betamethasone valerate aerosol (800 microgram/day) for control of their asthma. Four of 41 patients on the corticosteroid aerosol developed thrush compared with none of 40 in the control group. However, the number(More)
An open, parallel comparison of flunisolide and beclomethasone dipropionate nasal sprays is described. Sixty patients entered the study of whom fifty-six completed the full 4 weeks' therapy. The dosage of flunisolide was two actuations (25 micrograms/actuation) into each nostril twice a day (total 200 micrograms). The dosage of beclomethasone dipropionate(More)
A double-blind, cross-over comparison of flunisolide nasal spray and its inactive aqueous vehicle has been carried out in fifty patients suffering from perennial allergic rhinitis. Patients were randomly allocated to two groups; the first group (group I) received flunisolide for 3 weeks and then placebo for 3 weeks while the regimes were given in the(More)
The leaves and seeds of Cassia tora (Family Caesalpinaceae) are used in the treatment of leprosy, ring worm, flatulence, colic, dyspepsia, constipation, cough, bronchitis and cardiac disorders in the Ayurvedic systems of medicine. The present study deals with the study of macroscopic characters of the leaves, ash values, extractive values, behavior on(More)
A single-blind, crossover study was carried out in 43 asthmatic patients to compare the efficacy and tolerance of inhaled ipratropium bromide with inhaled salbutamol. One or other drug was given 3-times daily (0.04 mg ipratropium bromide or 0.2 mg salbutamol per dose) over a period of 4 weeks. Patients were then crossed over to the alternative medication(More)
