The study to an analyse of 726 samples of sea water, taken monthly (1977-1978) at 23 stations. At the basis of the data concerning the NPP of total coliformas, 75,5% of the samples point out a clean water for the bathing place, 11,04% = "acceptable" and 9,96% = "dirty". Considering the data about the MPP of fecal coliformas and of fecal streptocques, the sanitary state is reported in 94,23% "clean for the bathing place", 1,77% "acceptable" and 4% dirty.

Deficiency in the secretion of luteinizing hormone-releasing hormone (LHRH) from the median eminence (ME) is one of the factors limiting reinitiation of estrous cycles following parturition in cows. In previous studies, administration of naloxone, an opioid receptor antagonist, to postpartum cows increased LH secretion, suggesting that endogenous opioids inhibit the secretion of LHRH. This study employs quantitative light microscopy to describe morphological changes in the distribution of immunoreactive beta-endorphin (ir-beta-END) neurons in the hypothalamus of anestrous early postpartum (EPP, days 10-16, n = 5), midpostpartum (MPP, days 33-43, n = 4) and multiparous cycling cows (CYC, months 12-14, n = 4). Cryostat sections (60 microns) of perfusion-fixed ventral diencephalon and forebrain were immunostained with anti-beta-END serum via the biotin-avidin-peroxidase method or double stained sequentially with anti-LHRH serum, then anti-beta-END serum. In all cows, beta-END immunoreactive perikarya, mostly bipolar neurons, were located in the arcuate and periarcuate nucleus (ARC), with some perikarya in the ME. Within the ARC, the percentage area immunostained for ir-beta-END was greater (p < 0.01) for the CYC than EPP cows, with MPP intermediate but not significantly different from the other groups. Consistent for all cows, the percentage area of ir-beta-END in ventral ARC regions was greater (p < 0.05) than dorsal ARC regions. Fibers from these neurons coursed into the anterior hypothalamus, preoptic area and bed nucleus of stria terminalis. Ventrally projecting fibers entered the ME forming a densely staining band within the external layer.(ABSTRACT TRUNCATED AT 250 WORDS)
