Halothane anesthesia (1%) administered in 21% oxygen for 4 hr to an outbred strain of guinea pig in the absence of enzyme induction resulted in liver damage in 40 of the 65 animals studied. Necrosis was either confluent around the central veins or in scattered foci throughout the lobules. Damage was present on the second and third days after anesthesia. By(More)
OBJECTIVE To determine the effects of the amount of break removed and cauterisation time on neuroma formation in hens. DESIGN A pathology study with controls. ANIMALS Twenty domestic fowl were beak-trimmed. Three non-beak-trimmed domestic fowl were used as controls. PROCEDURE Beaks of two age groups with two levels of beak removal and either 2 s or 4(More)
Substance P immunoreactive (SP-IR) nerve fibres were identified using fluorescence immunohistochemistry and the length of the labelled individual nerve fibres was measured using confocal microscopy of whole mounts of the lateral wall of the ankle joint in 2-week-old domestic chicks. In the normal ankle there was an extensive network of SP-IR fibres in the(More)
The pathology of halothane hepatotoxicity is described in detail in a guinea-pig model. Twenty-two of 40 guinea-pigs developed liver damage after exposure to 1% halothane in 21% O2 for 4 h. The other 18 animals showed no evidence of hepatic injury. Two distinct patterns of damage were identified: mild damage, in which livers had focal areas of necrosis, and(More)
After ovariectomy and 3 daily injections of progesterone plus one of oestradiol-17 beta, 69% of stromal capillaries of the rat uterus became sheathed with pericytes. On Day 5 of pregnancy the value was 74% but at other times (Days 4 and 6) and with progesterone-only or not treatment less than 15% of capillaries were associated with pericytes. This period of(More)
In a randomized prospective controlled study in humans, the metabolism and hepatic effects of a single administration of halothane were compared with enflurane and meperidine. Pre- and postoperative antipyrine pharmacokinetics, intraoperative indocyanine green clearance, liver histology, and postoperative liver function tests were determined in 24 patients(More)

Four classes of neurons were identified in both juxta-jejunal and juxta-rectal ganglia of Remak's nerve of the domestic fowl using double-labeling immunohistochemistry. Neurons immunoreactive (IR) for tyrosine hydroxylase (TH) formed a mutually exclusive subpopulation from neurons displaying calbindin (CaBP)-IR. Between 48-72% of juxta-jejunal neurons(More)
Micro-injections of biocytin were made into neurons in whole-mount preparations of Remak’s nerve of the domestic fowl to visualise the morphology and projections of Remak’s neurons. Remak’s neurons were classified into four distinct morphological types. Remak type-I and -II neurons had a morphology resembling that of mammalian sympathetic neurons. Type-I(More)
1. Scanning electron microscopy was used to assess the relationship between the layers of the eggshell and egg viability. The relative thickness (absolute and %) of the mammillary, palisade, vertical crystal and cuticle layers relative to the total eggshell were measured over a 30-week laying period in 2 broiler breeder lines having different hatchability(More)
The distribution and chemical content of cutaneous nerves in 3- to 13-day-old emu chicks (Dromaius novaehollandiae) were examined by using double-labelling immunohistochemistry. Seven different subpopulations of cutaneous nerves were identified based on their neurochemistry. No intraepidermal nerve fibres were found. However, axons were located within the(More)
