Regression analysis was done as the appropriate statistical method to observe the dependence of various parameters, such as number and diameter of chief cells and oxyphil cells with age.
Parenchyma showed two types of epithelial cells in adults, chief cells and oxyphil cells (Figure 1).
Oxyphil cells were seen as large polygonal cells about 9-12 [micro]m in size.
Appearance of oxyphil cell was noticed at the age of seven years.
In late ages, large nodules of oxyphil cells were observed.
Diameter of oxyphil cells showed a gradual increase from childhood to old age.
Oxyphil cells: Oxyphil cells were observed and quantitatively studied.
DISCUSSION: The present study was carried out to reveal sexual differences about stromal fat & oxyphil cells in adult human parathyroid glands.
Present study revealed that oxyphil cells were less numerous than chief cells, placed either at periphery of gland adjacent to capsule or in the centre of gland.
(1949) (15) quoted that oxyphil cells are arranged as continuous masses & anastomosing columns whereas Gardner D.
(1949) (15) stated that great majority of adenomatous nodules of oxyphil cells are highly vascular with widely patent capillaries filled with blood.
Step serial sections of the right inferior parathyroid showed one cluster of WCCs, but otherwise the gland consisted almost entirely of chief cells, with rare small clusters of transitional
oxyphil and
oxyphil cells.
