The main objective of this work is to establish the quantitative and qualitative study of parenchymal cells of human parathyroid glands in different age groups and find out the relative proportion of these cells related to age.
During fruit development, the size of parenchymal cells also increased in both cultivars by 3% in "Clapp's Favourite" and over 19% in "Conference." In the fruit set stage, the thickness of the layer extending over three parenchyma layers was 12% higher in the "Clapp's Favourite"; in turn, the thickness of the parenchyma layer in the harvest maturity stage was by ca.6% higher in the "Conference" fruits (Table 1).
In the liver, PPAR[alpha] responses involve not only the parenchymal cells of the liver (hepatocytes), but also macrophages (Kupffer cells).
ALT and AST levels are related to the liver parenchymal cells. Liver parenchymal cells are destroyed directly by microorganism and could be modified by immunological causes.16 It is reported that enzyme activities such as ALT and AST are increased if liver parenchymal cells are modified.

(3) This infection triggers the release of proinflammatory cytokines from the liver parenchymal cells and membrane permeability that is resulting in the AST and ALT enzymes production.

Ultrasonography was done which showed changes in the renal parenchymal cells. [4] Renal biopsy report was also suggestive of AIN.
He believed that oncocytes were the result of a degenerative phenomenon in salivary gland parenchymal cells. Zimmermann observed the presence of oncocytes in the sublingual gland and referred to these cells as "pyknocytes" alluding to their condensed nuclear chromatin or pyknotic nuclei [1].
Activated innate immune cells release abundant inflammatory cytokines (e.g., tumor necrosis factor and interleukins) that initiate inflammatory and also cell death signaling cascades in immune cells and parenchymal cells [2].
Our main findings are that (1) transfused mitochondria are taken up into rat lung epithelial and parenchymal cells, (2) this effect is enhanced by SW therapy, and (3) SW plus mitochondrial therapy alleviates inflammation and ARDS damage within the lung parenchyma.
Renal tubular epithelial cells are one kind of renal parenchymal cells, and they play an important role in the maintenance of renal allograft function.
