ABSTRACT
The aim of this project is to determine the dimensions of the cranium and the cranial cavity and the intracranialvolume in goats, using 64 adults. The dimensions of the cranium and cranial cavity were measured throughmetric tape and paquimeter, considering the intervals of the largest distances. To determine the intracranialvolume, balloons of latex were introduced in the cranial cavity, through the magnum foramen, later on, filledwith water that was transferred for graduate test tube. The average and the standard deviation of length, widthand height of the cranium, in millimeters, were respectively: 218.01 ± 6.96, 120.17 ± 10.01 and 108.14 ± 4.46.The average and the standard deviation of length, width, height, in millimeters, and of the volume of thecranial cavity, in cubic centimeters, were respectively: 109.31 ± 7.25, 61.36 ± 4.51, 63.85 ± 2.88 and119.31 ± 12.21. It was observed that, the width of the cranium possesses positive significant correlationswith the length (r = 0.6865), with the height (r = 0.5644) and with the intracranial volume (r = 0.5436).They were still established, positive significant correlations among the height of the cranial cavity, with thelength (r = 0.5682) and with the intracranial volume (r = 0.5473). Differences were evidenced between malesand females, in relation to the dimensions of the cranium and cranial cavity. There wasnt difference of theintracranial volume in function of the sex of the goats.

Foram estudados fragmentos da mucosa duodenal obtidos de nove pacientes apresentando sintomas leves de estrogiloidiase, nove com sintomas moderados, sete com sintomas graves e sete indivíduos aparentemente normais. A muramidase(lisozima) foi imunocitoquimicamente demonstrada em cortes contracorados pela técnica do PAS. Havia aparente aumento progressivo na secreçao de muramidase pela célula de Paneth aaacompanhado o agravamento dos sintomas, näo obstante o fato de que a sua populaçao permanecesse constante. Decréscimo progressivo no número de células caliciformes foi observado enquanto, concomitantemente, haavia aumento na populaçao de células intermediarias. Esses resultados foram interpretados como a indicaçao da participaçao do sistema imune inato intestinal no estabelecimento da interaçao Strongyloides stercoralis/hospedeiro, através do aumento da secreçao da enzima mucolítica muramidase
