Sialochemistry of KCS patients

Sialochemistry was used to detect salivary gland involvement in KCS patients. Significantly elevated IgA was found in 52% of the patients, potassium in 48% and sodium in 32%. No correlation between the grade of Schirmer's test and the extent of changes in salivary composition was observed. The results indicate that salivary IgA, K and Na concentrations can be used for detection of salivary gland involvement of KCS patients.

Sialochemistry of patients with rheumatoid arthritis. Electrolytes, protein, and salivary IgA

Sialochemistry was undertaken to detect subclinical involvement of salivary glands in patients with rheumatoid arthritis (RA). The concentrations of salivary sodium and IgA were significantly elevated in 24 percent of the RA patients. Eighty per cent of the patients with elevated sodium and IgA concentrations had keratoconjunctivitis sicca as well. No correlation between serum and salivary IgA levels was found. The results indicate that salivary sodium and IgA levels can be used for detection of subclinical salivary gland involvement and for follow-up of RA patients.

Salivary IgA and serum IgG and IgA in recurrent aphthous stomatitis

Salivary flow rate and sIgA were measured in twenty-one patients suffering from recurrent aphthous stomatitis (RAS). Out of this group ten volunteered for continuous study. In these patients salivary IgA and serum IgA and IgG were measured every 3 days for 3 weeks. All parameters were in the physiologic range of healthy people. No correlation with the clinical condition of the patients was found.

Relation between idiopathic glossodynia and salivary flow rate and content

From a series of 50 patients complaining of sore tongue, 13 were found to be suffering from idiopathic glossodynia. All were women in the postmenopausal stage. The salivary flow rate, protein, phosphate, and electrolyte content (Na, K, Ca, Mg) were measured in unstimulated saliva of these patients. Protein, potassium and phosphate concentrations were significantly higher than in the control group. The results indicate that hormonal disbalance might be a factor in the etiology of this type of sore tongue.

Effects of irradiation on saliva in cancer patients

Whole unstimulated saliva was analyzed in 15 healthy individuals and 15 patients with malignant tumors in the head and neck region before and during irradiation therapy. Flow rate, pH, electrolytes (Na, K, Ca, Mg), protein and phosphate were measured. There was a decrease in rate of flow, and pH changed towards acidity. The most significant finding was the increased sodium content. We believe that irradiation reduces the reabsorption ability of the tubuli, causing the sodium content of the saliva to increase.

Defective deoxyribonucleic acid replication of T4rII bacteriophage in lambda-lysogenic host cells

Sedimentation of the replicative deoxyribonucleic acid through alkaline sucrose gradients showed that rII single chains reached the half-mature size at a time when wild-type molecules formed long chains (dimers and trimers of genome size). Long rII single chains could be observed on substitution of tris(hydroxymethyl)aminomethane buffer for Na(+)K(+) phosphate in the growth medium.
