With the increasing age of boars, the possibility of androstenone (5α-androst-16-en-3-one (AND), 5α-androst-16-en-3α-ol (α-AND), and 5α-androst-16-en-3β-ol (β-AND)) occurrence increases as well. The aim of this study was to evaluate concentrations of androstenone compounds in the saliva of boars concerning the age of animals. In total, 72 boars were evaluated (24 boars per replication). The effect of age (three different ages—152, 163, and 172 days) was observed, and (Landrace × Large White) × Pietrain genotypes were used. Chemical analysis of saliva samples was conducted by multidimensional gas chromatography/mass spectrometry (MDGC/MS). Salivary α-AND increased with age (p < 0.05), and positive correlations were found between age and submaxillary salivary gland weight (p < 0.05), age, and salivary AND concentration (p < 0.05), body weight and submaxillary salivary gland weight (p < 0.05), submaxillary salivary gland weight and salivary β-AND concentration (p < 0.05), as well as submaxillary salivary gland weight and total salivary 5α-androstenone (AND total) concentration (p < 0.001). Nowadays, animal welfare is becoming a more and more discussed topic, and pig breeding is not an exception. Specifically, the castration ban is a current issue, so it is very important to know as much as possible about compounds responsible for boar taint. Androstenone’s appearance in boars’ saliva could be one of the most important precursors for future early detection of boar taint.

Needle Aspiration Cytology

Background: Fine needle aspiration cytology is a minimally invasive technique used in the initial diagnosis of different types of lesions located in head and neck region commonly originating from cervical lymph node, thyroid gland, salivary glands and soft tissues. The objective of this study was to evaluate the diagnostic accuracy, sensitivity and speci city of FNAC in various head and neck lesions in correlation with their histopathological examination. Materials and methods: A hospital based prospective study was conducted among 209 patients with palpable head and neck region swellings in the Department of Pathology, Bhaktapur Cancer Hospital and the Department of Pathology, Nepal Medical College from August 2014 to July 2015. FNAC were done from palpable masses of head and neck regions. Data entry and analysis were done using SPSS 17. Result: There were 209 FNAC cases enrolled, out of which lymph node lesions (n=128) were the most common lesions followed by thyroid (n=40), other soft tissues (n=27) and salivary gland (n=14). Reactive lymph nodes, colloid goiter, epidermoid cyst and sialadenosis were the predominant diagnosis of lymph nodes, thyroid gland, soft tissues and salivary gland respectively. Highest accuracy, sensitivity and speci city were observed in thyroid gland, salivary gland and soft tissues. However, four false negative results for malignancy were reported in lymph node lesions. Conclusion: Head and neck region swellings are the commonly encountered conditions. FNAC being highly accurate, sensitive and speci c makes it useful and reliable procedure for screening and diagnosis of palpable masses in head and neck region.

Submaxillary Salivary Gland

A loss of electrical conductivity after circulatory arrest was observed in the submaxillary salivary gland, liver, kidney, and skeletal muscle. A drop in conductivity of 85–90% of the original value developed in about 0.5 hr in the liver. In the kidney the loss was less severe. Salivary glands lost about 70–80% of their conductivity in 1.5 hr. The losses in muscle conductivity developed late and were not greater than 50%. The drop in conductivity observed in the various organs after circulatory arrest can be accounted for by losses of extracellular electrolytes from the tissues, which could be demonstrated in preparations stained for chloride. In this context the electrolytes in the blood plasma have to be included in the extracellular compartment. The extracellular electrolytes are lost either because they are transported into the intracellular compartment or because they leave the tissue with blood that flows out of the organ after circulatory arrest.
