Electrophysiology of Mosquito Anal Papillae
The anal papillae of mosquito larvae are classic transporting epithelia that can absorb inorganic ions from extremely dilute external media. Since the original investigations of Wigglesworth (1933a,b,c) and Koch (1938) studies have been made of the ultrastructure of the papillae (Copeland, 1964; Sohal & Copeland, 1965; Meredith & Phillips, 1973a,6), of radio-cation fluxes (Treherne, 1954; Stobb...
متن کاملA Mitochondrial Pump in the Cells of the Anal Papillae of Mosquito Larvae
Mosquito larvae were raised to fourth instar in distilled water in order to maximally stimulate the salt-absorbing function of the anal papillae. Two exceptional features are observed, at the fine structure level, in the epithelial lining of the papillae. At the basal (cuticular) surface of the cells, the cell membrane is thrown into deep, narrow, parallel folds. The folds not only follow a rig...
متن کاملHypertrophied anal papillae and fibrous anal polyps, should they be removed during anal fissure surgery?
AIM Hypertrophied anal papillae and fibrous anal polyps are not given due importance in the proctology practice. They are mostly ignored being considered as normal structures. The present study was aimed to demonstrate that hypertrophied anal papillae and fibrous anal polyps could cause symptoms to the patients and that they should be removed in treatment of patients with chronic fissure in anu...
متن کاملPharmacological characterisation of apical Na+ and Cl- transport mechanisms of the anal papillae in the larval mosquito Aedes aegypti.
The anal papillae of freshwater mosquito larvae are important sites of NaCl uptake, thereby acting to offset the dilution of the hemolymph by the dilute habitat. The ion-transport mechanisms in the anal papillae are not well understood. In this study, the scanning ion-selective electrode technique (SIET) was utilized to measure ion fluxes at the anal papillae, and pharmacological inhibitors of ...
متن کاملRemoval of hypertrophied anal papillae and fibrous polyps improves outcome of anal fissure surgery
Background: The presence of Hypertrophied anal papillae and fibrous anal polyps are often ignored in the proctology practice. But the experience is that they tend to produce minor but disturbing symptoms. This study is aimed to assay the impact and utility of attending to these two conditions concurrently while dealing with cases of fissure in ano. Material and Methods: A study was carried out ...
