RESUMEN
In this study, and attempt was made to differentiate between follicular neoplasms of the thyroid using an immunoperoxidase staining technique for detection of ceruloplasmin. 54 histologically proved benign and malignant thyroidal lesions were selected. The staining for ceruloplasmin was consistently positive in follicular carcinoma and negative in follicular adenoma.

Acetic acid is used conventionally for enhancement of the colposcopic image. We used sulphosalicylic acid instead of acetic acid in 50 normal cases. The normal appearance was enhanced in all cases. The image was also enhanced in 70% cases of cervical intraepithelial neoplasia and 90% cases of cervical condyloma accuminata. The image was not inferior to that with acetic acid in any of the cases.

One hundred and twelve cases of cervical pathology (58 paraffin sections and 54 cervical smears) were assessed by PAP technique and 30 cases by indirect immunofluorescent technique. Forty-two normal cervical smears from the age matched controls were stained by indirect immuno-fluorescent technique. HSV-2 antigen was detected by PAP method in 86 out of 112 cases (78.57%) i.e. 50/55 squamous cell carcinoma, 13/13 carcinoma in situ, 11/15 severe dysplasia, 3/4 moderate dysplasia and 9/16 mild dysplasia. The amount of antigen was maximum in squamous cell carcinoma and decreased in carcinoma in situ, severe, moderate and mild dysplasia in descending order. Three cases of adenocarcinoma cervix were negative. Only one case out of 42 controls was positive. HSV-2 antigen was detected by an indirect IF technique in 8/9 squamous cell carcinoma, 2/3 carcinoma in situ, 3/7 dysplasia, O/1 adenocarcinoma and 4/10 inflammatory cases. The above findings support the association between HSV-2 and squamous cell carcinoma cervix, as well as carcinoma in situ which is statistically significant.
