Fibroadenoma vulva: Experience based on FNA of vulvar lesion.

Vulval fibroadenoma is an extremely rare lesion, mostly seen in young adults. A 51-years-old woman presented with a painless, mobile, and pedunculated vulval mass. Fine-needle aspiration (FNA) was performed and was diagnosed as a benign fibroepithelial lesion possibly fibroadenoma vulva, which was later confirmed as fibroadenoma vulva histopathologically.

Influence of iodothyronine conjugates of bovine serum albumin and horseradish peroxidase on enzyme immunosorbent assay of thyroid hormones.

Enzyme-linked immunosorbent assays (ELISA's) reported for thyroxine (T₄) and 3,5,3'-triiodothyronine (T₃), involved coupling of the haptens through (i) carboxylic group to carrier protein for producing antibodies and (ii) amino group to detection labels. To improve the titer and specificity of antibodies, immunogens were prepared by coupling of carboxyl group to bovine serum albumin (BSA) either directly or through adipic acid dihydrazide (ADH), after protecting amino group through acetylation of T₄ and T₃. Direct coupling resulted in the incorporation of 40-50 moles of T₄ and T₃ per BSA molecule and helped in improving immunogenic response and specificity, especially of T₄.
