Abstract

The objective of this study is to observe the relationship of development of adrenocorticotropic hormone (ACTH) cells of adenohypophysis–adrenal cortex axis during pre and postnatal period of longtailed monkey (Macaca fascicularis). Five fetuses aged 70, 85, 100, 120, and 150 days of gestation and 2new born aged 10 and 105 days old were used as research materials. The sections of the pituitary gland stained immunohistochemically using human ACTH antiserum and the adrenal glands stained by Hematoxylin-Eosin procedures. At the fetus 120 days old, the ACTH cells and blood vessel of fetaladenohypophysis developed well and its similar that found in older age. This condition suggested distributing the ACTH to whole body optimally. At the same time, the adrenal cortex cells of fetus 120 days old were active in proliferation and differentiation processes to form transition zone that lies between definitive and fetal zones, and central vein also developed in adrenal gland. In fetus aged 150 days, the cortex adrenal structure was similar with found in older fetus. The adenohypophysis ACTH cells developed earlier than adrenal cortex and their secretion suggested influencing the development of adrenal cortex cells of long-tailed monkey.

Abstract

This study was conducted to investigate the histological characteristic, type, and distribution of connective tissue in Sunda porcupine skin. The investigation was carried out in three adult of sunda porcupines at microscopic level using hematoxylin eosin, Masson thrichrome, Verhoeffs van Gieson, alcian blue pH 2.5 and periodic acid Schiff staining methods. Skin consists of epidermis, dermis hypodermis, and subcutaneous muscle. Quill follicles were the main and dominant structure as well as the specific characteristic on Sunda porcupine skin. The connective tissue was distributed well in basal membrane, dermis, quill follicle, and hypodermis with various intensity and density. The collagen was the main fiber found in the skin while the elastin fiber was not observed. The acid carbohydrate was found distributed well in the skin while the neutral carbohydrate was not detected in this study. In addition the fibers of connective tissue associated with the adipose tissue which found plentifully in quill follicles and hypodermis. The present results showed that the wide distribution of connective tissue might have an important role on the wound healing physiology of Sunda porcupine skin.
