Quantitative lacrimal scintillography. I. Method and physiological application.
Quantitative lacrimal scintillography, using 99mTc sulphur colloid, a high resolution gamma camera, and quantification using a digital computer, is a highly effective way of assessing lacrimal physiology, and of establishing normal flow and drainage values against which pathological cases may be compared.
متن کاملQuantitative lacrimal scintillography. II. Lacrimal pathology.
Quantitative lacrimal scintillography is a useful clinical procedure in assessing lacrimal drainage function in patients with epiphora. Examples are presented of patients with canalicular disease, lid abnormalities, 'functional blocks', and dysthroid disease, in which this technique was valuable. Information regarding the dynamics of a functioning and non-functioning dacryocystorhinostomy is el...
متن کاملLacrimal scintigraphy. III. Physiological aspects of lacrimal drainage.
Lacrimal scintigraphy (LS) was performed on asymptomatic lacrimal drainage systems and the results were evaluated to understand the physiology of lacrimal drainage. It was found that a physiological obstruction can exist at the level of the nasolacrimal duct in normal asymptomatic individuals, and it is suggested that this obstruction is due to the resistance offered by the valve of Hasner, whi...
متن کاملI-12: Physiological ICSI
Prior to ICSI the cumulus-oophorous-complex of the oocyte is commonly remove with impure animal-derived hyaluronidase of low strength. The lower strength of the enzyme, the high concentration of impurities and the necessity of extensive time-dependent mechanical denudation damages of the oocytes, increases the risk of lysing the oocytes and the transfer of animal-derived pathogens. All this can...
متن کاملPhysiological Signals Based Quantitative Evaluation Method of the Pain
Quantitative analysis of pain is extremely difficult, because it is a subjective and individual sensation caused by the potential or existing observable tissue injury. For individuals with major cognitive or communicative impairments, it is necessary to carry out an effective method to quantify pain without self-report. Focusing on using physiological signals of the human body to evaluate pain,...
