ABSTRACT
It was our intention to determine the C3c fraction in the serum and in the parotid saliva of 13 clinically normal individuals by the radial immunodiffusion method. The mean value of the seric C3c was 86.92 mg/dl and the confidence levels averaged 75.53 to 100.31 mg/dl. There was no measurable concentration of C3c in the parotid saliva.

The activity of lactic dehydrogenase in the serum and the saliva of the right and left parotid glands was determined in 32 individuals considered clinically normal. They were divided in groups according to the sex and the age. There was no difference of lactic dehydrogenase activity related to age and sex.

The labial salivary glands from seventy patients with systemic lupus erythematosus (twenty cases), systemic progressive sclerosis (twenty-two cases), rheumatoid arthritis (twenty-three cases), and Sjögren's syndrome (five cases) and from fifty subjects without connective tissue diseases were studied by means of light and fluorescence microscopy. The availability of the lip biopsy as a diagnostic tool is stressed, but a differential diagnosis between the different connective tissue diseases was not achieved. Yet some of the latter disclosed peculiar lesions. The role of the inflammatory and degenerative components, as well as the pathogenesis of the lesions, is discussed.
