The distribution of caveolin isoforms was previouslyevaluated in the retinas of different species, but has notyet been described in the primate retina. In this study, thedistribution of caveolins was assessed via immunochemistryusing isoform-specific antibodies in the retina of the black-and-white ruffed lemur. Here, we report the presence of avariety of caveolin isoforms in many layers of the lemurretina. As normal human retinas were not available forresearch and the retinas of primates are fairly similar tothose of humans, the lemur retina can be utilized as amodel for caveolin distribution in normal humans.

2.Nematode parasite, Auchenacantha spp of flying lemur, Cynocephalus variegatus (Audebert, 1799) from Indonesia: Morphological study with SEM.
Asian Pacific Journal of Tropical Biomedicine 2011;1(6):434-438
OBJECTIVETo observe morphology of Auchenacantha galeopteri (A. galeopteri), Auchenacantha spinosa (A. spinosa) and Auchenacantha parva (A. parva) from Sukabumi and Ujung Kulon, Indonesia using scanning electron microscopy (SEM).
METHODSSpecimens for light microscopy examination were fixed with warm 70% alcohol, cleared and mounted in lactophenol for wet mounting. Drawings were made with the aid of a drawing tube attached to a Nikon compound microscope. Specimens for SEM examination were processed according to Bozzola. Measurements were given in micrometers (µm) as the average of findings, followed by the range in parentheses, unless otherwise stated.
RESULTSThe measurements of Auchenacantha spp are same with those of previously described. The striations of male and female A. galeopteri are widen towards outside and wavy. The mouth of female with 6 lips, each of them is wider at base than distal end in A. galeopteri and rectangular in A. spinosa. Both species have dentiform protrusion from inner surface of lips, such structure absent in A. parva, but the lips with transverse festoon like pattern at anterior end of each lip.
CONCLUSIONSUsing SEM, the lip and the striation pattern of three species of Auchenacantha can be clearly distinguished. Sukabumi and Ujung Kulon are new locality of A. galeopteri and A. spinosa, and A. parva is the new record in Indonesia.
