Inflammatory responses have to be carefully controlled, as high concentrations and/or prolonged action of inflammation-related molecules (e.g. reactive oxygen species, nitric oxide and pro-inflammatory cytokines) can be detrimental to host tissue and organs. One of the potential regulators of the
Functional endoscopic sinus surgery (FESS) is one of most common surgeries in otorhinolaryngology practice. It is done in the narrow confines of the nasal cavity. Bleeding into the surgical field is a major problem faced by endoscopic surgeons. To assess the effectiveness of pterygopalatine fossa
The protonated adrenaline (PAd(+)) forms supramolecular complexes with crown ethers by extensive hydrogen bond and ion-dipole interactions. Recent experiments and calculations have demonstrated the molecular recognition of PAd(+) through the supramolecular complexes formed between 12-crown-4 (12C4)
Occurrence of acute and unilateral blindness after local anaesthesia combined with adrenaline, for the treatment of dental caries. The blindness was caused by vasospasm of the central retinal artery. The dentists should be warned about possible visual complaints after use of local anaesthesia, which
The activation of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1) with L-adrenaline and histamine has been investigated by kinetic and X-ray crystallographic studies. L-Adrenaline behaves as a potent activator of isozyme CA I (activation constant of 90 nM), being a much weaker activator of
The present investigations in cats were designed to study the effects of local anaesthetics containing adrenaline and felypressin (octapressin) on dental pulp function. Intradental sensory nerve excitability was measured using electrodes placed in dentinal cavities in canine teeth. Changes in pulp
A 24 h lasting long term adrenaline application in the form of subcutaneously implanted retard-tablets causes functional and morphological changes in the kidney, which are dose dependent and either reversible or irreversible. Animals in the V 15 group received one 15 mg and in the V 30 group two 15
1. Injection of 0.5-2.0 units of vasopressin or 25-100 mug of adrenaline into the peritoneal cavity of pregnant rats produced a transient slowing of the foetal heart. The bradycardia could be induced in foetuses after 15-21 days of gestation. Foetal heart rates dropped from normal values of 140-180
A 13-month-old pug with severe trismus because of suspected masticatory muscle myositis underwent anaesthesia for magnetic resonance imaging. When regurgitation occurred, the tongue was pulled from the mouth to enable suctioning but could not be repositioned into the oral cavity as it was not
The macrocyclic bisphosphonate 2 forms complexes with amino alcohols, amines, and amino acid esters with high association constants in polar organic solvents. Exertion of solvophobic interactions inside the macrocyclic cavity in DMSO and methanol leads to specificity for guest molecules with
OBJECTIVE
To observe the anesthetic effect of combined superficial anesthesia and auricular point injection for nasal endoscopy surgery.
METHODS
Forty cases of grade I - II as ASA for nasal endoscopy surgery were randomly divided into a combined auricular point injection and superficial anesthesia
A case of cardiac paraganglioma is reported in a 30 year old man operated two years previously for bilateral carotid body paraganglioma. Due to the persistence of high catecholamine levels in the superior vena cava, a cardiac localization, suspected on echocardiography, was confirmed by coronary
Knee arthroscopy in locally anesthetized ambulatory patients has been performed by filling the knee joint with 50 ml to 60 ml of 0.5% prilocaine, with adrenaline and with additional local infiltration at the sites of puncture. During the arthroscopic procedure the joint cavity is further distended
Background. . Local anesthesia is given to decrease pain perception during dental treatments, but it may itself be a reason for pain and aggravate the dental fear. Computer-controlled local anesthetic delivery system (CCLADS) is one of the alternatives for decreasing the patients' pain during
The aim of this study was to evaluate the influence of five intranasal applications of capsaicin, performed after endoscopic polypectomy associated with partial middle turbinectomy and anterior ethmoidectomy, on the recurrence of nasal polyps and the intensity of nasal obstruction and rhinorrhea.
