Ultrastructural observations on the hamuli of the monogenean gill parasite Cichlidogyrus halli typicus.
  • M. El-naggar
  • Biology, Medicine
  • International journal for parasitology
  • 1 September 1993
TLDR
The ultrastructure of a monogenean hamulus is described for the first time and it is suggested that the longitudinally orientated rods of the central core may provide inner strength to resist the physical strain on the hook and the outer and possibly the middle layers may provide chemical resistance to host's tissue secretion.

Ultrastructural observations on the oviduct, Mehlis' glands and ootype of the monogenean Cichlidogyrus halli typicus (Price & Kirk, 1967) Paperna, 1979
TLDR
The ancyrocephaline monogenean gill parasite Cichlidogyrus halli typicus has a short oviduct/ovo-vitelline duct separated from the germarium and from the ootype by sphincter muscles which may facilitate fertilization by retaining an oocyte temporarily in close contact with the free nucleated ends of the spermatozoa.

Neuromusculature of Macrogyrodactylus congolensis, a monogenean skin parasite of the Nile catfish Clarias gariepinus
TLDR
Structural and functional correlates of the neuromusculature of the pharynx, haptor and reproductive tracts were examined and results implicate acetylcholine, FMRFamide-related peptides and serotonin in sensory and motor function. Expand
Ultrastructural observations on the marginal hooklets of the monogenean gill parasite Cichlidogyrus halli typicus.
  • M. El-naggar
  • Biology, Medicine
  • International journal for parasitology
  • 1 August 1992
The marginal hooklets of adult Cichlidogyrus halli typicus have the same morphology, each being composed of a handle, a curved blade with a tapering guard and an accessory domus. In addition, all theExpand
Superoxide dismutase activities in serum and white blood cells of patients with some malignancies.
TLDR
It is concluded that the assay of leukocyte SOD can be used to differentiate between HD and NHL in both adults and children. Expand
Discorhabdins revisited: cytotoxic alkaloids from southern australian marine sponges of the genera Higginsia and Spongosorites.
Chemical analysis of southern Australian marine sponges of the genera Higginsia and Spongosorites has yielded examples of the discorhabdin class of alkaloids. These include the known metabolitesExpand
Utility of Slot‐Blot‐ELISA as a New, Fast, and Sensitive Immunoassay for Detection of Carcinoembryonic Antigen in the Urine Samples of Patients with Various Gastrointestinal Malignancies
TLDR
A Slot‐Blot Enzyme Linked Immunosorbent Assay (SB‐ELISA), based on anti‐CEA monoclonal antibody (CEA‐mAb), is established as a new, simple, fast, cheap, and non‐invasive immunodiagnostic technique for detection of CEA in the urine of GIT patients. Expand
Chaetotaxy of the monogeneans Macrogyrodactylus clarii and m. congolensis from the gills and skin of the catfish clarias gariepinus in Egypt, with a note on argentophilic elements in the nervous
TLDR
A comparison has been made between the chaetotaxy of the gyrodactylid monogeneans MacrogyrodACTylus clarii Gussev and M. congolensis from the gills and skin of the catfish Clarias gariepinus from the river Nile in Egypt. Expand
Transplantation of Modified and Fresh Hepatocyte Reduces Hepatotoxicity Induced by Carbon Tetrachloride
TLDR
The conclusion of the above study showed that the animal groups that transplanted with microencapsulated hepatocytes survived without any immune rejection for the same period in comparison with fresh hepatocyte transplantation treated with immunosuppressive drug (cyclosporin), beside semi similar liver function recovery. Expand
Scanning electron microscope observations on the digenean intestinal parasite Astiotrema reniferum (Plagiorchiidae).
The body surface of adult digenean intestinal parasite Astiotrema reinferum (Looss, 1898) Stossich, 1904 has been studied using scanning electron microscopy (SEM). The posterior region of the bodyExpand
