Considering the epidemiological effect of radon on human beings, an attempt is made to make a nation-wide atlas of Rn and Rn for India. More than 5000 measurements have been carried out in 1500 dwellings across the country, India. The solid state nuclear track detectors were deployed for the measurement of indoor Rn, Rn and their progeny levels. The mean annual inhalation dose rate due to Rn, R...

The unidirectional flow through the gas-exchanging bronchi of bird lungs is known to be effected by (1) the structure of the major bronchi and (2) a pressure difference between the cranial and caudal air sacs. To study the effects of bronchial structure, simple physical models of bird lungs were constructed. They suggested that, to achieve unidirectional flow, air in the caudal portion of the p...

The effect of smoke inhalation injury on fluid requirement was assessed retrospectively. A total of 131 burn patients were classified into two groups: burn patients with smoke inhalation injury (Group IB: 73 patients) and burn patients without inhalation injury (Group B: 58 patients). Fluid resuscitation was commenced according to the Parkland formula and the infusion rate was modified to meet ...

The BREELIB nebulizer was developed for iloprost to reduce inhalation times for patients with pulmonary arterial hypertension (PAH). This multicenter, randomized, unblinded, four-part study compared inhalation time, pharmacokinetics, and acute tolerability of iloprost 5 µg at mouthpiece delivered via BREELIB versus the standard I-Neb nebulizer in 27 patients with PAH. The primary safety outcome...

BACKGROUND Anxiety is the one of the most common problems before the surgery. Its prevalence rate ranged from 11 to 80 percent in all the adult patients. Delay in wound healing and increasing use of narcotics and anesthetics are some of the other accompanying problems. Aromatherapy is one of the complementary medicine components. It is applied by special type of oil extracted from aromatic plan...

The clinical response to sodium cromoglycate treatment was compared with its concentration in serum. Twenty five children with asthma entered a 10 week trial of two baseline weeks followed by eight weeks of treatment by the inhalation of 20 mg of sodium cromoglycate spincaps four times a day. Individual clinical response was determined by the differences between baseline and treatment periods o...

Ventilated cigarettes were designed to reduce the levels of smoke under machine testing conditions; however, smokers alter their smoking pattern to compensate for the reduction in yields. A relative shift in incidence of lung cancer from the more central lung airways to the alveolar region has also been associated with ventilated cigarette use. Validated mathematical models indicate that partic...

OBJECTIVE Sleeve resections were introduced to preserve lung function in patients with limited pulmonary reserve. Ischaemia and infection of the distal part of the anastomosis is the leading cause of bronchial anastomotic leakage. We have learned from our experience in lung transplantation that inhalation with Tobramycin helps prevent anastomotic insufficiency. We would like to present our expe...

We have measured how a low concentration of nitrous oxide affected respiratory sensation and ventilation. Severe dyspnoea was induced in nine normal subjects by a combination of hypercapnia and inspiratory elastic load (50 cm H2O litre-1). Subjects were asked to rate their sensation of respiratory discomfort using a visual analogue scale (VAS) while breathing either 20% nitrous oxide or 20% nit...

Exposure to hypoxia and subsequent development of pulmonary hypertension is associated with an impairment of the nitric oxide (NO) mediated response to endothelium-dependent vasodilators. Inhaled NO may reach resistive pulmonary vessels through an abluminal route. The aim of this study was to investigate if continuous inhalation of NO would attenuate the development of pulmonary hypertension in...
