After injections of horseradish peroxidase involving the whole primary (SI) and secondary somatosensory (SII) areas of adult cats, 16-21% out of 2220 counted neurons in the nucleus ventralis posterolateralis were unlabelled. The mean areas of perikarya of these neurons varied between 111.8 +/- 32.3 microns2 and 180.8 +/- 48.6 microns2. The size of perikarya(More)
The pronephric kidneys were examined in upstream migrant sea lampreys, Petromyzon marinus L., by transmission and scanning electron microscopy. Each pronephros consists of an enlarged renal corpuscle (glomus) and ciliated nephrostomes, but there are no renal tubules. The renal corpuscle contains an extensive mesangium, which consists of a highly fibrous(More)
Corneal sensory and sympathetic nerves exert opposing actions on corneal mitogenesis and wound healing. The mechanisms by which these nerves exert their actions are unknown; however, the release of axonally transported neuropeptides has been postulated. In the present study, we investigated changes in innervation densities of calcitonin gene-related peptide(More)
Rabbit testicular contractions and intratesticular pressure were recorded in vitro as temperature was increased from 33 to 38 degrees C. The response of the testicular capsule to several physiological agents was quantified at 35, 37 and 38 degrees C. A corresponding increase in intratesticular pressure was observed with each contraction. Uniform(More)
1. Maximum testicular development and plasma testosterone levels occurred at spring emergence from aestivation-hibernation (A-H), followed by a regression to basal state in June. 2. A slight testicular recrudescense occurred just prior to immergence into A-H, but this development was not accompanied by a definitive increase in plasma testosterone levels or(More)
OBJECTIVE To study temporal changes in amounts of viral DNA in blood leukocytes over long periods, and to determine whether severity of the disease is greater in experimentally induced, compared with natural, infection. ANIMALS 18 naturally and 6 experimentally infected black mink; 26 naturally infected brown mink. PROCEDURE Polymerase chain reaction(More)
The stimulatory effect of histamine on rabbit and rat testicular capsule was blocked by the H1 blocker, diphenhydramine, but not by the H2 blocker, cimetidine, suggesting the presence of H1 histamine receptors in both rabbit and rat testicular capsules. In the rabbit, both anti-prostaglandin F (PGF) and anti-prostaglandin E (PGE) effaced spontaneous(More)
The regression of the pronephric kidney of the lamprey, Petromyzon marinus, is described using histochemical and ultrastructural techniques. Regression begins in the third year of larval life, and by the time the animal enters metamorphosis the tubules have all disappeared. The nephrostomes and the renal corpuscle, however, persist for the remainder of the(More)
