title: [Adrenergic innervation of swine ovaries in various periods of pregnancy].
abstract: The present paper focuses on morphological characteristics of adrenergic nerves in the ovaries of sows in various periods of pregnancy and on the determination of noradrenaline content in these nerves. The experiment included 37 primigravidas (150 kg body weight). The animals were divided into 5 groups: 13th day of pregnancy (n = 9), 20th day of pregnancy (n = 6), 30th day of pregnancy (n = 7), 60th day of pregnancy (n = 8), 90th day of pregnancy (n = 7). Both ovaries were removed after slaughter and thorough bleeding. The adrenergic nerves were detected in the ovaries by the method of Torre and Surgeon whereas noradrenaline content was determined by Change's method in Brodie's modification. Morphological features of adrenergic nerves and their distribution were described for the examined ovaries. It was found that the number of adrenergic nerves in sows decreased in the final period of pregnancy. The highest content of noradrenaline was noted on 30th day of pregnancy and the lowest on 90th day. The present paper contains further data proving a correlation between steroid hormones (such as estrogen and progesterone) and functionality of adrenergic nerves.
