Estimation of Actual and Ideal Bodyweight Using Morphometric Measurements and Owner Guessed Bodyweight of Adult Draft and Warmblood Horses

The breeding biology of tree frog, Polypedates teraiensis was studied during the breeding season at Mizoram University Campus. It was found that sound production by male during the breeding season was primarily a reproductive function and advertisement calls attract females to the breeding areas and announce other males that a given territory is occupied. The aim of this study was to provide the detailed information on the breeding behaviour and the advertisement calls of Polypedates teraiensis. The morphometric measurements of the amplecting pairs (males and females) for sexual dimorphism along with clutch sizes were also studied.

Complete Blood Counts

Since 2002 the Denver Zoological Foundation has produced 28 African hunting dog (Lycaon Pictus) puppies in 3 litters (7, 14 and 7 pups) from the same dam and sire. Wellness examinations were performed on each puppy. The wellness examinations spanned the range of 6-14 weeks of age. During the wellness examinations, in addition to physical examinations and vaccinations, blood samples for complete blood counts and sera biochemistry were obtained.Weights, morphometric measurements, rectal cultures for enteric pathogens and dental eruption patterns were recorded. Blood samples from each age group were compared with adult values from the Denver Zoo. It was noted that animals from the 14-pup litter were 63.6 % of the mean weight of the two 7-pup litters, but size differences (in, for example, total bodylength) were less apparent. Two organisms were recovered from rectal cultures, namely Yersinia enterocolitica (n = 2) and Plesiomonas shigelloides (n = 3). The following deciduous eruption patterns were also noted; at 6 weeks, I1-3, i1-3, C1, c1, P1-2 and p1-2 (n=7) were present, at 9-10 weeks, P3 and p3 (n=21) , and finally at 12-14 weeks, P4 (n = 28).

Pulmonary Arterial

The effect of CPPV on edema formation in lungs perfused at constant blood flow was studied in whole dogs and in isolated dog lungs. In intact animals, subjected to an increase in left atrial pressure relative to pleural pressure of 40 Torr, pulmonary shunts correlate inversely (r = -0.82) with the level of end-expiratory pressure (PEE). CPPV had no significant effect on total extravasation of liquid even though PEE higher than 20 Torr was effective in preventing liquid from accumulating in the airways. In isolated lobes, perfused at constant blood flow and at a venous pressure of zero, accumulation of liquid occurred when PEE was increased above 8–10 Torr. At comparable levels of pulmonary arterial pressure, an increase in PEE resulted in lesser accumulation of liquid than when pulmonary venous pressure was elevated. Morphometric measurements revealed no significant difference in the distribution of accumulated liquid within the lung parenchyma between lobes made edematous either by raising venous pressuure or by raising PEE. It would appear that CPPV, while beneficial in improving arterial oxygen tension in pulmonary edema, does not prevent extravasation of liquid in lungs perfused at constant blood flow. High levels of PEE appear to damage the lung by favoring accumulation of liquid in the extravascular spaces of the lung.

Analysis System

We studied the effects of hypoxia and hyperoxia on the angiogenesis process in the chick embryo chorioallantoic membrane (CAM) using four different morphometric measurements of vascularity. Chick eggs were incubated in various oxygen atmospheres (12, 16, 21, 45, or 70% oxygen) beginning on the 7th day of development, and vascularity was measured on the 14th day. Measurements of vascularity included vessel endpoint density (VED), length density, fractional image area, and a vascular density index. All measurements were made on blood vessels in randomly selected areas of CAM using a computerized image analysis system. An opaque colloidal carbon-albumin perfusate was used as a vascular marker. All four measurements showed that vascularity of CAM was inversely related to the oxygen tension to which the embryos were subjected. The VED, an estimate of total number of pre- and postcapillary vessels, exhibited the greatest degree of change, but overall changes in vascularity were modest. Prolonged exposure to a 12% oxygen atmosphere increased VED by approximately 16%, whereas 70% oxygen decreased VED by approximately 19% compared with room air control groups. We also studied the normal growth of CAM vasculature from days 8 to 18 of development. In these studies, the values of VED increased progressively throughout the entire period of development, whereas the other measurements of vascularity reached maximum values by the 14th day. We conclude that hypoxia stimulates angiogenesis in the CAM in a dose-related manner, hyperoxia inhibits CAM angiogenesis in a dose-related manner, and VED provides a sensitive estimate of vascularity in chick CAM throughout its development.
