The endocannabinoid system mainly consists of cannabinoid receptors type 1 (CB1R) and type 2 (CB2R), their endogenous ligands termed endocannabinoids (eCBs), and the enzymes responsible for the synthesis and degradation of eCBs. These cannabinoid receptors have been well characterized in rodent and monkey retinae. Here, we investigated the expression and localization of the eCB system beyond th...

In the vervet monkey Cercopithecus ethiops Schlemm's canal was opened to the outside by a window through the sclera. The flow of aqueous was collected with sponges and weighed. In jour eyes the drainage ranged from 0.5 to 4.5 \iL per minute at the start. Fifteen minutes later it reached an average value between 0.2 and 2 fiL per minute depending on the animal. In 2 animals pressure in the opera...

To elucidate the organization of the serotoninergic innervation within the orbitofrontal cortex (OFC), serotonin transporter (SERT) density was quantified by autoradiography using [(3)H]cyanoimipramine binding. In six adult vervet monkeys, 15 architectonic areas were delineated according to cytoarchitectonic (Nissl), myeloarchitectonic (Gallyas) and chemoarchitectonic (acetylcholinesterase) cri...

Five juvenile vervet monkeys (Cercopithecus aethiops) were tested using the Cowey and Weiskrantz technique. The animals had access in the dark to distasteful biscuits of one shape and tasteful biscuits of another shape. Later they were shown a pair of biscuits, one of each shape, and the animal’s first selection was scored. A single pair of shapes was used with flavor assigned daily according t...

Phencyclidine, 1 to 1.2 mg. per kilogram body weight, is recommended for examination of the eyes in untamed monkeys. Applanation tonometry with the Mackay-Marg machine was performed in 109 vervets (Cercopithecus ethiops), mainly old males, contributing a total of 208 eyes without signs of present or past inflammation or trauma. A mean pressure of 17.7 mm. Hg was found. The detailed distribution...

In Amboseli National Park, Kenya, both superb starlings, Spreo superbus, and vervet monkeys, Cercopithecus aethiops, give acoustically different alarm calls to different classes of predators. The 'raptor alarms' of starlings and vervet monkeys are so called because they are given exclusively to avian species that attack from the air. In contrast, while vervets give 'leopard alarms' to a narrow ...

monkeys are important experimental models for investigating human diseases. the aim of this study was to survey the alimentary tract parasites among imported vervet monkeys (cercopithecus aethiops) to iran. fecal samples were collected from 40 vervets imported from tanzania to razi vaccine and serum research institute of iran. fecal samples were assessed by direct smear and telman sedimentation...
