Introduction: The influence of morphine on pituitary secretion through µmu receptors has been nearly known. It is also reported that morphine has an effect on cell proliferation. In the present study we investigated the effect of morphine on the proliferation of acidophil cells of adenohypophysis in male rat. Method: This study has been carried out on 14 adult male Wistar rats divided into two ...

The examination of haematoxylin and eosin stained sections of normal and neoplastic pituitary glands under ultraviolet light illumination discloses fluorescence of acidophil cells. The distinction between prolactin and growth hormone-producing cells is not possible. Such fluorescence depends on previous eosin staining.

The adenohypophysis of the threespine stickleback, Gasterosteus aculeatus, was studied light-microscopically to determine and estimate the cell types and their function. For these purposes, the adult specimens obtained during the period from migration to spawning were examined. Further, the juveniles caught in the spawning bed were subjected artificially to sea water. The rostral pars distalis ...

Light microscopy has revealed that the anterior lobe of the pituitary gland contains many kinds of glandular cells, which have been classified according to the staining behavior of each cell type after the use of various methods of differential staining. At the early stage in the development of pituitary morphology, the cell types were designated as acidophil, basophil or chromophobe suggesting...

A review is made of the various histological lesions observed in hepatitis B virus-related liver diseases, including different forms of acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The elementary lesions discussed include acidophil necrosis (apoptosis), confluent lytic necrosis in its different patterns, piecemeal necrosis, focal necrosis, and dysplastic hepatocytes. Th...

The maximum temperature for growth (T(max)) was determined for pure and mixed cultures of acidophilic thiobacilli. The experimental system was based on incubating the cultures in liquid media exposed to a linear temperature gradient. The T(max) values varied within the range of 36.1 to 43.6 degrees C.
