Electron microscopic study on the pancrease of albino rat after bilateral vagotomy

Thirty adult male albino rats were included in this study and divided into six equal groups. Bilateral vagotomy was done in four groups, while the other two groups were used as control animals. Generalized swelling of mitochondria of acinar, insular and ductular cells as well as of the nerve terminals appeared by the third day after operation. These changes were more apparent by the 7th, 15th and 30th days with vascular congestion, hemorrhage and cellular infiltration. The early changes were first within the limits of the physiological parameters and destructive process soon occurred

Proprioceptive innervation in the orbital muscles of goat

The aim of this work was to study the proprioceptive innervation of the orbital muscles of goat. Typical muscle spindles were found in the medial rectus, lateral rectus and superior oblique muscles. Each spindle consisted of number of intrafusal fibers and definite capsule. Semi-thin sections in the cranial three, four and six close to the brain stem were prepared and the diameters of the myelinated fibers measured and counted in 2 mu intervals. The three cranial nerves contained fibers ranging from 2 to 18 mu which indicated that the proprioceptive fibers from the orbital muscles pass to brain stem via these nerves
