Delayed hypersensitivity in squamous cell carcinoma of the oral cavity.

Delayed hypersensitivity response to Dinitrochlorobenzine (DNCB), Purified Protein Derivative (PPD) and Candida albicans abstract (Dermatophytin 'O') was observed in 60 patients of squamous cell carcinoma of the oral cavity and 40 normal controls. The response to all these three antigens were significantly impaired in cancer patients as compared to normal controls. PPD and Dermatophytin 'O' response showed progressive decline with increasing tumour burden. Patients with well differentiated tumours responded well to all these three antigens as compared to those with poorly differentiated tumours.

Serum immunoglobulins in squamous cell carcinoma of the oral cavity.

Serum immunoglobulins (IgG, IgA, and IgM) have been studied in 70 patients with squamous cell carcinoma of oral cavity and in 40 age-matched normal controls. The results were correlated with clinical stage, tumor size, lymph node status, tumor differentiation, and treatment modalities. There was a significant rise in serum IgM and IgA in oral cancer patients as compared to controls. It was further raised in advanced clinical stage, but tumor size and histological differentiation and treatment modalities (surgery and chemotherapy) do not seem to affect serum immunoglobulin levels. The observations implies that the extension and dissemination of tumor mass is the important factor for the change in serum immunoglobulin level in squamous cell carcinoma of the oral cavity.

Fibrillary lines of the cornea. A clinical sign in keratoconus.

Fibrillary lines, whether in the normal cornea or in keratoconus, are faint structures which must be searched for diligently with the appropriate biomicroscopical settings, using a high magnification and oblique focal illumination of high intensity. They are unlikely to be confused with other superficial linear changes in the cornea, such as mare's tail epithelial lines, fingerprint lines and their variants, ring lines, and so on. A detailed description of these and other entities is given elsewhere (Brown and Bron, in preparation).

Effect of acetazolamide on insulin sensitivity in dogs with alloxan diabetes.

The effect of acetazolamide on the sensitivity to exogenous insulin in the alloxanised diabetic dogs was studied. The administration of acetazolamide caused acidosis and insulin resistance. The liver insulinase activity of diabetic dogs after acetazolamide administration was also studied to evaluate the role of this enzyme for the destruction of exogenous insulin. It was observed that insulinase did not play role for the development of insulin resistance after acetazolamide administration.
