dem·i·lune bod·y

a circular body of extreme transparency except for a crescentic punctate substance on one edge, which contains hemoglobin. The body is much larger than a red blood cell, but is thought possibly to be a degenerated red blood cell swollen by imbibition; it has been found in malaria and in convalescence from typhoid fever; the transparent portion is called the glass body.

Gold leaf the front edge of the top of the demilune table by painting a coat of red basecoat on the front edge of the tabletop.
Types of glandular acini and number of mucous, serous acini and demilunes were also counted.
Some of the mucous acini on were capped by basophilic cells, as crescent shape demilunes (Fig .3).
The mean number of serous demilunes in "a" and "b" parts of right and left gland was calculated and their difference was statistically insignificant (p Greater than 0.05, table-1).
After pooling the data difference between the mean number of acini, demilunes, ducts and the mean diameter of the ducts of right and left glands was found to be statistically insignificant.
Some of the mucous acini were capped by serous cells called demilunes. This finding was similar to that of Ichikawa and Ichikawa14, but not in agreement with the findings of Eversole12 that in human sublingual glands demilunes have seromucous cells.
The sublingual glands are mixed (Fig.2), composed of mucous acini with scattered serous demilunes. The mucous cells possess spongy cytoplasm and flattened and basal nuclei.
The mucous acini have clear cellular limits; the nuclei are confined to the basal cytoplasm and are capped by large serous demilunes. The acinar lumen is small and irregular.
5), been almost exclusively formed by mucous acini with scarce and small serous demilunes. The mucous cells were only slightly stained whit AB and reacted strongly to PAS.
In the anterior lobe the mucous portion is strongly PAS + and AB pH 2.5 +, while the demilunes and serous acini react intensely with PAS and are negative to the AB pH 2.5 (Figs.
