Changes in anti-Müllerian hormone concentrations in bitches throughout the oestrous cycle. The utilization of exfoliative cytology as a diagnostic tool is dependent in part upon the decreased adherence of malignant cells to each other, and to well-defined cytostructure indications of malignancy. Urine cytology 5. Bronchial brushing and bronchial wash specimens are obtained via flexible fiber-optic bronchoscope (FOB). Residual material can be rinsed in collection medium and used to process additional LBP for special stains, immunostains, or cell block preparation, especially if tissue fragments are noted. Exfoliative cytology is a tool for assessing oral mucosal lesions. 4. The principal indications for exfoliative cytology of the respiratory tract are as follows: 1. Procedure: This technique involves examination of exfoliated cells scraped from suspected oral lesions. Carcinomas, both of the small cell and non-small cell types, are by far the most common malignancy of the respiratory tract. Oral exfoliative cytology can be a powerful tool for early detection of malignant and premalignant lesions as well as for some viral and fungal infections, if the limitations of the method are thoroughly understood and appreciated by the dental clinician. Metastatic malignant neoplasms, from almost any site, can metastasize to the lung. For central tumors, the diagnostic sensitivity of bronchial brushing and bronchial wash is lower than that of transbronchial biopsy (TBBx). , Christopher VandenBussche2 and Syed A.

The switch to metoestrus is associated with a large number of neutrophil granulocytes and a sudden change of cytology within 24-48 hours. Due to the oestrogenic influence, an increase in cell layers, keratinisation and exfoliation is observed in the follicular phase during prooestrus, such that the 3-4 layered epithelium in anoestrus becomes 20-layered during oestrus.
