Investigations into the qualitative characteristics of kid goat meat were done on the meat of 44 crossbred kid goats of domestic Balkan White and Saanen goat at the age of 3–4 and 6–7 months. The results showed that the highest average percentage of water contained the meat of a male kid goat at the age of 6–7 months (76.45 %), while the lowest was in the meat of a male kid goat at the age of 3–4 months (70.73 %). The highest content of proteins was found in the meat of a male kid goat at the age of 6–7 months (21.28 %), while the lowest was in the meat of a female kid goat in younger investigated groups (19.14 %). The highest content of fats was in the meat of a female kid goat at the age of 3–4 months (5.53 %), while the lowest was in the meat of a male kid goat in the younger investigated group (1.21 %). Quantity of mineral matters in both age and sex groups ranged from 1.06 to 1.17 %. Due to its physical-chemical values, kid goat meat from both age and sex groups is considered a very valuable product in human nutrition.

AIM Oxytocin produces concentration-dependent relaxation of isolated isthmus and ampulla of human oviduct precontracted by histamine. The aim of our study was to investigate whether this oxytocin effect was specific and by which receptors it was mediated. METHODS We investigated effects of oxytocin and its antagonists on isolated isthmus and ampulla of the uterine tubes from 20 women who underwent surgery for uterine fibroids. Selective vasopressin and oxytocin antagonists were used to treat isolated preparations of the tubes. RESULTS In a concentration-dependent manner, oxytocin enhanced spontaneous relaxation of both isthmus (EC50=1.23+/-0.03 x 10(-7) mol/L) and ampulla (EC50=1.04+/-0.26 x 10(-7) mol/L) precontracted by histamine. Neither predominantly selective vasopressin V1 receptor antagonist, [beta-mercapto-beta,beta-cyclopentamethylene-propionyl1,0-metyr2,arg8]-vasopressin (1.0 x 10(-9)-1.0 x 10(-7) mol/L), nor predominantly selective vasopressin V2 antagonist, [1-(beta-mercapto-beta,beta-cyclopentamethylene-propionic acid), 2-D-isoleucine, 4-D-isoleucine]-arginine-vasopressin (1.0 x 10(-9)-1.0 x 10(-7) mol/L) affected significantly the relaxation of isolated ampulla and isthmus produced by oxytocin. On the other hand, [Deamino-Cys1,D-Tyr (Et)2, Thr4, Orn8]-oxytocin, a selective blocker of oxytocin receptors, produced in a concentration-dependent manner (6.7 x 10(-9) mol/L, 2.0 x 10(-8) mol/L, and 6.7 x 10(-7) mol/L) significant shifts of the concentration-response curves of relaxation for oxytocin to the right in isolated preparations of both the ampulla and the isthmus. The values of pA2 for [Deamino-Cys1,D-Tyr (Et)2, Thr4, Orn8]-oxytocin calculated from constrained Schilds plot were 8.08+/-1.53 for ampulla and 7.94+/-0.67 for isthmus. CONCLUSION Oxytocin relaxes smooth muscles in human oviduct through a specific effect on oxytocin receptors.

The Municipality of Cazin is situated in the North-West part of B&H more precisely in Canton Una-Sana. It occupies an area of 381 km2 and is positioned 317 m above the sea level. In the Municipality of Cazin we analyzed data obtained from 20 small family farms in May 2001. We chose farms by random sampling, so we used visual inspection, some measurements and inquiry about cattle breeds structure, age, productivity etc. at every farm. Finally, we analyzed the data and information obtained. In this paper, we present results on cattle categories and breed structure. We also give the most important information about housing and productivity of dairy cows in this municipality. Based on our investigation and results of the questionnaire, we can conclude that breed structure of cattle as well as housing and productivity of cows are satisfying taking into consideration the average of these parameters in Bosnia and Herzegovina today.
