Figures 46–51; Light micrograph of the integument of O. v-signata: (46) Dorsal region (HE-staining); (47) Dorsal region (AB-method); (48) Ventrolateral region (HE-staining); (49) Ventrolateral region (AB-method); (50) Ventral region (HE-staining); (51) Ventral region (AB-method). Melanophores (_) occur in the spongious dermis that is poorly developed in the dorsal region. The EK-layer (Æ) is a continuous layer in all integument regions. Apocrine glands (¬) with heterogeneous content occur in both ventrolateral and ventral regions. Serous glands are visualized in both dorsal and ventrolateral integument. Mixed glands () are observed in the ventral region. E = epidermis; CD = compact dermis.
Figures 16–18; (16) The basal portion of the syncytium with digitiform projections (p) and the clear space (*) between them and the myoepithelial cells. Notice the myoepithelial cells nuclei (n) and the collagen fibrils. (17) Detail of the connective tissue between two neighbor alveoli, with myoepithelial cells (m) and collagen fibrils (c). (18) The basal portion of a syncytium with intricate projection labyrinth. Notice the syncytium nucleus with irregular outline (n). Scale bars: 18 = 1 μm, 16, 17 = 3 μm.
Girino (Scinax machadoi), foto subaquática tirada no Parque Nacional da Serra da Canastra de nível Federal, localizado (a) em Vargem Bonita (MG), São Roque de Minas (MG), São João Batista do Glória (MG), Sacramento (MG), Delfinópolis (MG), Capitólio (MG)
Figures 32–35; Light micrograph of the integument of O. perpusilla: (32) Dorsal region (HE-staining); (33) Dorsal region (AB-method); (34) Ventrolateral region (HE-staining) (35) Ventral region (AB-method). The spongious dermis houses both apocrine glands with heterogeneous content (¬) and serous glands (Ø). Melanophores (_) occur in the dorsal integument, but they are not identified in either the ventrolateral or ventral region. Iridophores did not occur in all integument regions. The EK-layer (Æ) is a well defined continuous layer occurs as irregular deposits between the spongious and compact dermis of the ventral region. Cutaneous elevations (â) are separated by grooves (Ú) in the ventral region. CD = compact dermis.
Figures 3–10; Photomicrographs of histological sections of the male inguinal gland region of O. centralis. (3–6, 8) Histological sections stained with HE. 3) Section of skin from the peripherical region of the inguinal gland. Notice that only mucous glands are present. 4) Low magnification micrograph showing the presence of many syncytial glands (g), with arrows indicating the lateral limits of the inguinal gland. (4–6) Major magnifications of the glandular apical portion, with many melanocytes (m), mucous glands (mc) and myoepithelial cells (open arrows). Note the glandular ducts (dc). 7) Histological section submitted to PAS reaction. Notice that only some cells of the mucous glands (mc) exhibit a positive reaction (arrowheads). (8) Major magnification of the lateral base portion of the syncytium, with colloidal secretion (s) in syncytium cytoplasm. Note also a blood vessel in the connective tissue. (9) Methacrylate section treated with potassium permanganate and oxalic acid and stained with Nile blue. Notice the bleached melanocytes (m) and some syncytial cytoplasmic projections (*) through the glandular secretion (s). (10) Methacrylate section stained with toluidine blue. Notice the pale blue color of the secretion suggesting it is alkaline, contrasting with the dark blue color of the glandular syncytium (gs). (e) epidermis; (d) dermis; (black open arrow) myoepithelial cells; (c) blood cells. Scale bars: 5, 6, 8 = 10 μm, 3, 7, 9, 10 = 20 μm; 4 = 200 μm.
