Histochemical studies on bovine sweat glands

1. Histochemical tests have been applied to the socalled sweat glands and their secretions of Zebu and Ayrshire cattle, the former to only a limited extent.2. For skin specimens of Ayrshire cattle positive reactions were obtained for ribonucleoprotein, arginine and alkaline phosphatase. Negative reactions were obtained for desoxyribonucleoprotein and acid glycerophosphatase.3. Neither the sweat glands of Ayrshire cattle nor those of Zebu cattle gave positive reactions for fats, lipids or cholesterol and its esters, although these were all present in the sebaceous glands of both breeds. Detectable amounts of phospholipid were not found in the sweat glands of the Ayrshire cattle and their secretions.4. The chemical composition of the secretion of bovine sweat glands differs markedly from that of human eccrine or apocrine sweat glands in not containing detectable amounts of glycogen, lipids and associated compounds or iron.

Dermal Papillae

Light-microscope studies reveal distinctive features in the hair- and woolgrowing skin of adult sheep. The epidermis is variable in thickness-usually thin on wool-growing regions and thicker on haired regions. The follicles are mostly in groups containing one, two, or three primary (P) follicles and a number of secondary (S) follicles. The SIP follicle ratios vary from zero to about 30, depending on the breed and body region. The capillaries, myoepithelium of sweat glands, and dermal papillae of the follicles are often reactive for alkaline phosphatase. This enzyme is also asymmetrically distributed in some follicle bulbs and here it might be related in some way to the segmentation of the fibre cortex and perhaps to the formation of crimped wool. The dermal and follicle nerve networks contain cholinesterases. The latter may also contain alkaline phosphatase. Encapsulated end-organs and tactile disks are occasionally present in both hair- and wool-growing skin. Melanocytes, most common near the dermo-epidermal junction, may also be present in the outer root sheaths of the follicles, sebaceous glands, sweat glands, and dermis. Acetylcholinesterase-positive branched cells are invariably present in the epidermis in all regions where there are follicles. Sebaceous glands are associated with all follicles and apocrine sweat glands with the P follicles only. The P follicles also possess erector muscles that react for cholinesterases. Both the subaceous glands and sweat glands are usually larger in haired regions than in wool-growing regions. Large "eccrine" glands open on the naked part of the muzzle.

Elephant Seals

The arrangement, number, and anatomy of the facial vibrissa follicles of the southern elephant seal, Mirounga leonina (Linn.), are described. There are three groups of vibrissae: mystacial, supraorbital, and rhinal, containing approximately 38, 7, and 1 follicles, respectively. These specialized hairs appear to be retained for at least 2 yr and are not shed with the pelage hairs at each annual moult. The histology of the vibrissa follicles and associated organs is described and discussed in relation to their sensory function. Vibrissa follicles of elephant seals are different in anatomy from those described in the mouse and rat: the ringwulst is relatively smaller and, in addition to the sebaceous glands, there are tubular glands of unidentified function but resembling apocrine sweat glands.

The aim of the study was to investigate the biochemical parameters of blood serum, physicochemical properties and chemical composition of muscle tissue of young white pigs of English origin, as well as to calculate the level of correlations between the main quantitative traits. The experimental part of the work was carried out in LTd “AF” Dzerzhynets” Dnipropetrovsk region, Research Center for Biosafety and Environmental Control of Agricultural Resources Dnipro State Agrarian and Economic University, Ltd “Globinsky Meat Plant” Poltava region, laboratory of zootechnical analysis of the Institute of Pig Breeding and Agriculture and livestock laboratories of the Institute of Cereals NAAS. Blood sampling for biochemical studies was performed in 5-month-old animals, serum activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase and α-amylase was determined. Physicochemical properties and chemical composition of the longest muscle of the back (m. Longissimus dorsi) were studied on the indicators of “moisture holding capacity, %”, “color intensity, units. ext. × 1000”, “tenderness”, c, “fat content, %”, “total moisture content, %”, “protein content, %”, “heat loss, %”, and “energy value of muscle tissue, kcal”. It was found that the biochemical parameters of blood serum of young pigs of large white breed at 5 months of age correspond to the physiological norm of clinically healthy animals. Thus, the activity of aspartate aminotransferase (AST) is 1.33 ± 0.074 mmol/h/l, alanine aminotransferase (ALT) – 1.87 ± 0.063 mmol/h/l, alkaline phosphatase – 291.99 ± 12.517 IU/l,α-amylase – 169.82 ± 5.005 g/h×l. Studies of physicochemical properties and chemical composition of samples of the longest back muscle of young pigs of large white breed show that the number of high quality samples in terms of “moisture holding capacity, %” is equal to 12.0%, “color intensity, units. ext. × 1000” – 16.0 %, “tenderness, c” – 12.0 % and “fat content, %” – 16.0 %. Significant correlations were established between the following pairs of features: moisture holding capacity, % × protein content, % (-0.484 ± 0.1825, tr = 2.65), moisture holding capacity, % × heat loss, % -0.416 ± 0.1896, tr = 2.19), fat content, % × moisture holding capacity, %, (-0.450 ± 01862, tr = 2.42), fat content, % × energy value, kcal (0.836 ± 0.1144, tr = 7.31), alanine aminotransferase (ALT) activity, mmol/h/l × pH, units of acidity, (0.443 ± 0.1859, tr = 2.37), alkaline phosphatase activity, units/l × color intensity, units. ext. × 1000 (-0.483 ± 0.1826, tr = 2.65), alkaline phosphatase activity, units/l × P, % (0.484 ± 0.1825, tr = 2.65).

In the study, it was aimed to reveal the morphological, morphometric and histological characteristics of sinus interdigitalis found in the fore and hind feet of Konya merino sheep. For this purpose, the fore and hind feet of 10 Konya merino sheep, weighing between 44-79 kg, were used. Sinus interdigitalis were dissected out from the feet, and after morphometric measurements were made, morphological examinations were performed and photographed. The shape of the sinus interdigitalis, present in all the forefeet and hind feet, resembled a pipe consisting of neck and body. It was determined that the neck part was longer than the body at all feet. The inner surface of the gland was covered with hair, and there was more hair on the neck than on the body. The weight of the gland, body length and diameter, flexura, canal length and diameter were measured morphometrically. In the measurements made, it was determined that all the values of the forefeet were higher than the hind feet. In histological examination, it was found that the wall of the sinus interdigitalis consists of three layers: epidermis, dermis and fibrous capsule, and in the dermis, hair follicles, sebaceous glands, m. arrector pili and sweat glands were found.

Background: Skin is the largest organ of the body, accounting for 15-20% of the total body weight and acts as a barrier between the external and internal environment and maintain homeostasis.The sweat and sebaceous glands in dermis of skin play vital role in developing the adaptive ability to the heat stress. Besides this, the distribution pattern and number of these glands vary in different animals that may aid in identification of different species.Methods: The study was conducted on abdominal skin of 36 adult cattle, buffalo, horse, goat, pig and dog (six sample of each) collected from abattoir, Veterinary clinics and post-mortem hall of GADVASU, Ludhiana. After collection, the tissues were fixed in 10% neutral buffered formalin and processed for paraffin block preparation. The paraffin sections of 5-6 µm were cut and stained with hematoxylin and eosin stain. Result: The study revealed that the sebaceous glands were multilobular, alveolar glands comprised of several layers of epithelial cells and were associated with hair follicles in all species studied. The number of sebaceous glands/mm2 was significantly higher (p≤0.05) in goat (1.60± 0.11) than in pig (0.44±0.06) whereas sebaceous gland diameter was significantly higher (p≤0.05) in buffalo (109.83±6.14 µm) than in goat (61.16 ±2.42 µm).The sweat glands were of saccular and simple coiled tubular type and most of them were associated with hair follicles. The number of sweat glands/mm2 was the highest in horse (3.10 ± 0.24) and the least in buffalo (0.76 ±0.05). Sweat gland diameter was significantly higher (p≤0.05) maximum in buffalo (123±3.15 µm) and minimum in goat (50.33 ±2.85 µm) and the difference.

Apocrine Glands

Cutaneous glands in humans include holocrine or sebaceous glands and merocrine or sweat glands. Merocrine glands are subdivided into apocrine, eccrine, and apoeccrine glands. Disorders of each of these cutaneous glands have been associated with disease. Apocrine glands in adults are found predominantly in the axillae and anogenital regions, with a few located in the ear canal (ceruminous glands) and eyelids (Moll’s glands). Associated disorders include hidradenitis suppurativa, Fox–Fordyce disease, bromhidrosis, trimethylaminuria, and chromhidrosis....
