The volume and composition of the gastric contents as well as the rates of gastric emptying and secretion were determined simultaneously in conscious chair-adapted monkeys. These determinations were made during fasting and after a liquid meal, thereby allowing studies of the physiologic variables which regulate gastric emptying and gastric secretion. Administration of a water meal is followed by a complex pattern of changes in rates of secretion as well as the fractional rate of emptying. During administration of a 100-ml water meal (pH 7.4), intragastric volume increased while acid concentration decreased; both then returned to fasting values 50 min later. The fractional rate of emptying increased fivefold during administration of the water meal, returned to basal values after 30 min, and then increased again, indicating that gastric emptying cannot be characterized as a simple first-order process with a constant coefficient. The pattern of the change in the rate of water secretion was similar to that for fractional gastric emptying. In contrast, after the meal, gastric acid secretion increased steadily and did not become maximal until 20 min.

While much is known regarding the effect of lasers on the retina, little study has been done on the effect of lasers on cornea, because of the limitation of the size of the material. Using a combination of electron microscope and several newly developed cytochemical methods, the effect of laser can now be studied on eye for the purpose of correlating functional and morphological damage. The present paper illustrates such study with CO2 laser on Rhesus monkey.

Herpes-like viruses were isolated from rhesus monkey peripheral blood leucocytes when co-cultivated with WI-38 cells. The virus was originally designated rhesus leucocyte-associated herpesvirus (LAHV) and subsequently called Herpesvirus mulatta (HVM). The original isolations were from juvenile rhesus monkeys shown to be free of antibody to rhesus cytomegalic virus. The virus could only be propagated in human or simian fibroblasts. Use of specific antisera developed from HVM showed no relationship between this virus and other herpesviruses. An electron microscopic study was undertaken to determine the morphology of Herpesvirus mulatta (HVM) in infected human fibroblasts.

As a result of vasectomy, spermatozoa are confined to the epididymis and vas deferens, where they degenerate, releasing antigens that enter the circulation or are engulfed by macrophages. Multiple antigens of the sperm can elicit production of autoantibodies; circulating anti-sperm antibodies are found in a large percentage of vasectomized men, indicating the immunogenicity of the sperm. The increased prevalence of macrophages in the liomen of the rhesus monkey testicular efferent ducts after vasectomy led to further study of this region. Frozen sections were used for evaluation of immunopathological status by fluorescence microscopy with fluorescein-conjugated antibody. Subsequent granular deposits of immune complexes were revealed by positive immunofluorescence staining for complement. The immune complex deposition in the basement membrane surrounding the efferent ducts implies that this region is involved in antigen leakage (Fig. 1).
