    Co-Authors: Walailak J Sci, Sinlapachai Senarat, Jes Kettratad, Pisit Poolprasert, Ezra Mongkolchaichana, Watiporn Yenchum, Waristha Angsirijinda
    Abstract:

    The present study provides a description of the histological organization of the mesentero-proctodeal regions (midgut and hindgut) of adult Epicauta waterhousei (Haag-Rutenberg, 1880). The histological wall of the mesentero-proctodeal regions consists of 4 layers; mucosa, submucosa, muscularis and serosa layers, respectively. Midgut was classified into 3 subparts based partially on the size and characterization of the longitudinal fold; pro-midgut, meso-midgut and hind-midgut. Among these subparts, the longitudinal fold of the hind-midgut becomes progressively higher than other subparts. The mucosal epithelial lining of the midgut is a single layer of Simple Cuboidal Epithelium. Hindgut is classified into 2 subparts; illium and rectum. These parts are lined by Simple Cuboidal Epithelium with a surrounding thick layer of muscularis (inner circular and outer longitudinal muscular layers). However, the muscular layer of the rectum is thicker than the ilium. The present study provides baseline information about structural histology, but further fine descriptive investigation may be needed

  • type vii collagen associated with the basement membrane of amniotic Epithelium forms giant anchoring rivets which penetrate a massive lamina reticularis
    Placenta, 2013
    Co-Authors: C D Ockleford, S A Mccracken, L A Rimmington, A Hubbard, Nicholas A Bright, N Cockcroft
    Abstract:

    Abstract In human amnion a Simple Cuboidal Epithelium and underlying fibroblast layer are separated by an almost acellular compact layer rich in collagen types I and III. This (>10 μm) layer, which may be a thick lamina reticularis, apparently presents an unusual set of conditions. Integration of the multilaminous tissue across it is apparently achieved by waisted structures which we have observed with the light microscope in frozen, paraffin-wax and semi-thin resin sections. We have also captured transmission and scanning electron micrographs of the structures. These structures which cross the compact layer we call "rivets". The composition of these "rivets" has been examined immunocytochemically and in three dimensions using the confocal laser scanning epi-fluorescence microscope. The rivets contain type VII collagen and an α6 integrin. They associate with type IV collagen containing structures (basement membrane lamina densa and spongy coils) and a special population of fibroblasts which may generate, maintain or anchor rivets to the underlying mesenchymal layer. Although type VII collagen is well known to anchor basal lamina to underlying mesodermal collagen fibres these "rivets" are an order of magnitude larger than any previously described type VII collagen containing anchoring structures. Intriguing possible functions of these features include nodes for growth of fibrous collagen sheets and sites of possible enzymatic degradation during regulated amnion weakening approaching term. If these sites are confirmed to be involved in amnion degradation and growth they may represent important targets for therapeutic agents that are designed to delay preterm premature rupture of the membranes a major cause of fetal morbidity and mortality.

  • Systemic organization of Tetraponera rufonigra (Jerdon, 1851) (Hymenoptera: Formicidae): histological observation
    Pusat Sistematik Serangga Universiti Kebangsaan Malaysia, 2020
    Co-Authors: Naphat Somala, Sinlapachai Senarat, Chamnan Para, Wannee Jiraungkoorskul, Gen Kaneko, Thitiya Poonpet, Pisit Poolprasert
    Abstract:

    Tetraponera rufonigra Jerdon, 1851, is one of the most dangerous ants, whose apex of gaster region contains a sting structure with a complex venom gland. Here, we describe the systemic organ system of T. rufonigra using histological techniques. The venom gland of T. rufonigra was located above the mesentero-proctodeal region, which could be histologically classified into two parts; the venom gland reservoir and the venom gland tubes. The venom gland tubes were lined by a Simple Cuboidal Epithelium, whereas the venom gland reservoir was enclosed with Simple squamous Epithelium. The pygidial gland was localized near the cuticle as clusters, and each of the oval shape pygidial gland cells contained a spherical nucleus surrounded by acidophilic cytoplasm. High magnification observation showed that the integumentary system consists of three layers; epicuticle, exocuticle, and endocuticle. The digestive system was a single narrow tube consisting of the foregut, midgut, and hindgut. Five to six rectal papillae were found in the hindgut. The urinary system was made up of Malpighian tubules, which lined with Simple Cuboidal Epithelium and tracheal embedded in the adipose tissue. The respiratory system was composed of spiracles and trachea adjacent to the integument, all of which were surrounded by a Simple squamous Epithelium. In the nervous system, several ganglia were found in this study. There were two layers in each ganglion: outer cortex and inner medullar layers. Several cell types were observed in the cortex layer including the neurosecretory cells, the neuroglia, and neurons. The outcomes of this study could provide a useful basis for future research on the family Formicidae
