Laryngeal tissue

Much of the in-vivo work in H N as well as other sites has been led by Stone (a co-author of Chapter 4 in this book). His preliminary work, on laryngeal tissue, published in 2000, used linear disciminant analysis to separate spectra with the most visible differences being seen at 850, 950, 1200 and 1350 cm. He also concluded that the relative intensity of the nucleic acid peak increases with progression to malignancy. Not only do several publications indicate efficacy in the differentiation of non-malignant and malignant cell... 

The disadvantage are toxicity and flammability. Ammonia has a corrosive effect on tissues and can cause laryngeal, bronchial spasm and edema, which lead to obstructed breathing. Ammonia s flammability range in air is 16-25% by volume. It is usually characterized as hard to ignite (71). A suitable ammonia detection system with alarm should be installed and well maintained. Detectors should sound an alarm at the lowest practical level, not to exceed 1000 ppm.

Thrombin, a topical hemostatic, is indicated in bleeding from parenchymatous tissue, cancellous bone, dental sockets, during nasal and laryngeal surgery, and in plastic surgery and skin-grafting procedures. 

HUMAN HEALTH RISKS Inhalation human LCLo 50 ppm for 30 minutes Acute Risks extremely destructive to tissues of the mucous membranes, upper respiratory tract, eyes and skin burning sensation coughing wheezing bronchitis bone changes laryngitis shortness of breath headache nausea vomiting Chronic Risks fluorosis effects on liver, kidney, eyes, bones, skin and respiratory system. 

HEALTH SYMPTOMS Inhalation (irritates respiratory tract, lightheadedness, dizziness, headache, weakness, nausea, central nervous system effects) skin (mild irritation, loss of natural oils) eyes (damage to eye tissue) ingestion (nausea, vomiting, affects laryngeal, ocular, and respiratory muscles). 

ACUTE HEALTH RISKS irritation of skin, eyes and upper respiratory tract destructive to tissue of the mucous membranes inflammation of larynx and bronchi pulmonary edema chemical pneumonitis coughing laryngitis wheezing shortness of breath headache nausea vomiting allergic skin reaction. 

ACUTE HEALTH RISKS irritation of eyes, skin and upper respiratory tracts destructive to tissues of mucous membranes coughing wheezing laryngitis shortness of breath pulmonary edema inflammation of larynx and bronchi pneumonitis headache nausea vomiting death in high exposures. 

CHRONIC HEALTH RISKS long-term or repeated exposure may have effects on the eyes and respiratory tract may result in conjunctivitis, rhinitis, laryngitis and pharyngitis may cause impaired sense of smell and taste fibrosing alveolitis (growth of fibrous tissue in the lung) may develop. 

ACUTE HEALTH RISKS irritation to eyes, skin and upper respiratory tract destructive to tissues of the mucous membranes inflammation and edema of larynx and bronchi coughing wheezing laryngitis labored breath headache dizziness nausea vomiting confusion unconsciousness. 

If you breathe Lewisite or Mustard-Lewisite vapors, your airways will immediately become irritated. You could experience burning pain in the nose and sinuses, laryngitis, cough, shortness of breath, nausea, and vomiting. You could also experience airway tissue damage and accumulation of fluid in your lungs, which could result in death. 

Mojave rattlesnake (Crotalus scutulatus) bites deserve special consideration and caution, because neurologic signs and symptoms of envenomation may be delayed and there is often little swelling or evidence of tissue damage. The onset of muscle weakness, ptosis, and respiratory arrest may occur several hours after envenomation. Facial and laryngeal edema have also been reported.
