Abstract

The presence of glycoconjugates in caput, corpus, and cauda epididymis of the Javan muntjacs was performed using lectin histochemical method. The epididymis organs were obtained from two adult male Javan muntjacs in hard antler stage and then immediately fixed in Bouin’s solution and processed in histological manner. Six types of biotinylated lectins namely Peanut agglutinin (PNA), Soybean agglutinin (SBA), Wheat germ agglutinin (WGA), Ricinus communis agglutinin (RCA), Concanavalin A (Con A), and Ulex europaeus agglutinin I (UEA I) were applied to detect the specific glycoconjugates in the epididymal tissue of muntjacs. The result showed the presence of glycoconjugates were detected by five types of lectins except UEA I in caput, corpus, and cauda epididymis with specific distribution and also the intensity of lectins binding. Glycoconjugates β-galactose, β-glucose, mannose, N-acetyl-galactosamine, N-acetyl-glucosamine, and sialic acid were stained with various intensity in epithelial cells, basal cells, stereocilia, spermatozoa, and stroma of caput, corpus, and cauda epididymis. The presence of sialic acid on the surface of spermatozoa detected by WGA are thought to be play a role on sperm protection during their maturation and transit along epididymal lumen. In conclusion, the difference of glycoconjugates distribution pattern and lectin binding in the epididymal caput, corpus, and cauda of the Javan muntjac indicates the regional differences in epididymal function in spermatozoa maturation.

Abstract

The objective of this study was to determine the effect of ethanol extract of neem (Azadirachta indica) leaves on the number of spermatids and androgen receptor expression in the testicular tissue of New Zealand White (NZW) rabbits. Twelve adults male NZW rabbits with body weight (BW) 2-2.5 kg were divided into three treatment groups (n = 4), namely P1 (control group) given 0 mg/kg BW, P2 and P3 were given 200 mg/kg BW and 300 mg/kg BW of neem leaves ethanol extract respectively. The extract was administered orally using a gastric tube for 52 days. At the end of the treatment, the rabbits were terminated and the testes were collected to be processed into histological preparations and stained with Periodic Acid Schiff (PAS) staining to detect the number of spermatid and Immunohistochemical (IHC) staining to detect androgen receptor expression. The results showed that neem leaves extract administered at P3 rabbits significantly decreased the number of spermatids and androgen receptor expression in myoid peritubular cells and connective tissue P0.05), but not significantly different in the Leydig cells and blood vessels (P0.05) of testicular tissue. The conclusion of this study is that the ethanol extract of neem leaves at a dose of 300 mg/kg BW can be used as a contraceptive candidate compared to a dose of 200 mg/kg BW.
