Anal Sacs

The anal and perianal region contains multiple structure and glands, some of which are unique to the area. Anal sacs or perianal sinuses are paired, lateral, cutaneous, anal diverticula lined by a cornified, stratified squamous epithelium. Dogs have apocrine tubular anal sac glands that open into the anal sacs. Perianal glands are modified sebaceous glands, they are referred as hepatoid glands, because of their histologic resemblance to hepatocytes. Incidence,symptoms and surgical and medical management of anal tumors was studied.

Median Raphé

Median raphe cysts present anywhere between the external urethral meatus and the anus. The cysts can occur at parameatus, glans penis, penile shaft, scrotum, or perineum. Perianal region is an extremely rare location for these lesions. Here we present a 50-year-old male patient who presented with a cystic, fluctuant lesion, located at 12 o’clock in perianal region. Microscopic examination revealed a cystic lesion with keratinized and nonkeratinized stratified squamous epithelium, pseudostratified ciliated epithelium, and scattered goblet cells. The final diagnosis of the lesion was median raphe cyst. Ciliated cells and perianal localization in median raphe cysts are extremely rare characteristics.

Stratified Squamous Epithelium

The gross and microscopic structure of the auditory meatus of the harp seal (Pagophilus groenlandicus) is described from dissections and serial sections. The meatus bends ventrally from the oval external orifice, posteroventrally, ventrally, and finally medially into the cranium. The ventrally directed wall of the meatus is membranous, the posteroventral and ventrally directed wall is incompletely wrapped by cartilage, and the medially directed wall is bony. The areas between sections of the cartilaginous wall ate completed by connective tissue. The meatus is closed internally by the intrinsic helicis and antitragicus auricular muscles. The external orifice is closed by the superficial auricular muscles. The auditory meatus is lined with stratified squamous epithelium, sebaceous glands, and ceruminous glands. Longitudinal blood sinuses and elastic fibers in the hypodermis may function as a pressure regulating device during diving. Blood sinuses are most prominent in the bony region of the meatus and extend into the tympanic sulcus of the pars tensa. Blood sinuses engorged with blood and a closed meatus may enhance transmission of sound to the tympanic membrane when the seal is under water.

The stratified squamous epithelium which lines the ruminal compartment of the bovine stomach performs at least three important functions. (1) The upper keratinized layer forms a protective shield against the rough, fibrous, constantly moving ingesta. (2) It is an organ of absorption since a number of substances are absorbed directly through the epithelium. These include short chain fatty acids, potassium, sodium and chloride ions, water, and many others. (3) The cells of the deeper layers metabolize butyric acid and to a lesser extent propionic and acetic acids which are the fermentation products of rumen digestion. Because of the functional characteristics, this epithelium is important in the digestive process of ruminant species which convert large quantities of rough, fibrous feed into energy.Tissue used in this study was obtained by biopsy through a rumen fistula from clinically healthy, yearling holstein steers. The animals had been fed a typical diet of hay and grain and the ruminal papillae were fully developed. The tissue was immediately immersed in 1% osmium tetroxide buffered to a pH of 7.4 and fixed for 2 hrs. The tissue blocks were embedded in Vestapol-W, sectioned with a Porter-Blum microtome with glass knives and stained with lead hydroxide. The sections were studied with an RCA EMU 3F electron microscope.

(Abstract.)In man, in the rabbit, and some other animals the trachea is built up of a series of cartilaginous rings incomplete behind; the rings being completed in this position by the trachealis muscle.The mucous membrane forms a smooth cylindrical lining for the whole tube, and is covered by a ciliated epithelium.In the cat and dog the cartilage rings completely encircle the trachea, and overlap posteriorly, and the trachealis muscle, which is well developed, is placed outside the cartilage, and has a powerful action in varying the diameter of the tube.When this muscle contracts the overlapping ends of the cartilage ride one upon another, and the projecting ends form a vertical ridge down the inside of the trachea, which can be readily seen on slitting the organ open. This ridge is separated by a deep groove from the other end of the plate.

Zimmermann-Laband syndrome is an inherited disorder that is characterized by abnormalities of the head, face, hands, and feet. Most children with this disorder have generalized hypertrichosis, large gingivae, and hypoplasia of the fingernails and toenails. We report a male infant who exhibited typical features of Zimmermann-Laband syndrome with an unusual histopathologic finding. Excised tissue from the infant's gingivae showed papillary projections that were composed of hyperplastic stratified squamous epithelium with different amounts of keratinization.

The Southern Caracara is a bird of prey, of the family Falconidae, inhabits all the Brazilian territory, they are omnivorous birds adapted for hunting. The digestive system of the predators presents differences in their morphology due to their eating habits. Knowing the importance of the gastrointestinal system, this study aims to carry out a histological study of the tongue, esophagus and the crop of Polyborus plancus. For this purpose, eight avian of both sexes, with different body weights and ages were used, they were euthanized and the organs were collected, fixed, dehydrated and stained with hematoxylin-eosin. It was noted that the tongue has stratified squamous epithelium with mucous glands and with different degrees of keratinization. The esophagus and crop have four well developed muscle layers and mucous glands. Additionally, in the crop there is presence of an adventitious layer that consists of loose connective tissue. We conclude that the tongue, the esophagus and the crop of the Southern Caracara have similar histological organization of several birds like the Pekin Ducks, ostriches, domestic chicken and partridges.

Fissure in Ano ( Parikartika) is a vertical tear or an elongated longitudinal ulcer in the long axis of stratified squamous epithelium of the lower anal canal. Ancient text couldn’t give a brief idea about this condition. Mainly it has been described as complication of Bastikarma and Atisar. It is so named in which sharp cutting pain is felt in the anus. For that Modern surgical treatment of choice is again has limitations such as faecal incontinence. Hence, karpoor Ghrita having effective Vranaropan & vedanashamak, tridoshaghna  property i.e. it relieves burning sensation quickly. So we modified a method of Local Application is conceived for this study.
