Positive end-expiratory pressure (PEEP) was applied in 74 anesthetized, ventilated horses during colic surgery, to attempt to increase arterial oxygen tensions. In 28 horses with an initial PaO2 less than 70 mm of Hg, PEEP increased PaO2 values to a mean of 173 +/- 24 mm of Hg. Arterial oxygen
The purpose of this study was to determine foaling rates in mares presented for medical or surgical treatment of colic, and to examine risk factors associated with abortion following colic. A retrospective analysis of 153 medical records found that mares treated surgically for colic (P = 0.0007)
The records of 105 pregnant mares and 105 nonpregnant horses with colic admitted to an equine hospital were reviewed. The 2 groups had similar types of colic and short-term survivability. Of the 105 pregnant mares, 31 were treated medically and 74 required surgical intervention. Thirty-three of the
Blood cholesterol levels have been connected to high-altitude adaptation. In the present study, we treated mice with high-cholesterol diets following exposure to acute hypoxic stress and evaluated the effects of the diets on whole-body, liver glucose, and liver fat metabolism. For rapid cholesterol
Cavernous hypoxia is an important factor in the pathogenesis of vasculogenic erectile dysfunction (ED). Therefore, the hypoxia-inducible gene expression system can be exploited as gene therapy for vasculogenic ED. This study was undertaken to examine the effectiveness of a hypoxia-inducible gene
This study evaluated HIF-1α inhibitors under different hypoxic conditions, physiological hypoxia (5% O2) and severe hypoxia (0.1% O2). We found that chenodeoxy cholic acid (CDCA) reduced the amount of HIF-1α protein only under physiological hypoxia but not under severe hypoxia without decreasing its
The effects of prolonged intravenous infusions of cholic acid into fetal lambs are described in this study. The ewes (n = 10, 11 fetuses) were operated on at 114 days of gestation (term = 150 days) by placing plastic catheters in maternal and fetal vessels and in the amniotic cavity. Gestational
This article discusses anesthesia for horses with colic from acute gastrointestinal disease. Emphasis is placed on new developments in pre-, intra-, and immediate postoperative management over the last decade, including early goal-directed therapy (EGDT) in the resuscitation of septic patients, the
The medical records of pregnant mares over a 3-year period were reviewed. In all cases persistent pain or progressive abdominal distension were the main reason for referral. The overall survival rate for the 115 mares treated for colic was 73.9% (85 cases). The abortion rate was 20.5% in surgical
Effects of a sublethal IV dose (10 micrograms/kg of body weight) of Escherichia coli endotoxin were studied in 7 conscious ponies. Arterial blood gases and plasma lactic acid were determined periodically throughout the 180 minutes of the study. Arterial hypoxemia occurred within 5 minutes despite
Infants were recruited in four centres in North-West Italy. 138 infants were assessed for eligibility, 113 ones underwent randomisation and 105 completed the study. Newborns aged less than 10 days of life, with gestational age between 37 and 42 weeks, birth weight from 2,500 to 4,300 g and normal
In acute experiments on rats in vivo the stimulating effects of hydrophilic cholic acids (CA and UDCA) on the bilification and their inhibiting by rotenone have been shown. The secretion of CA and UDCA under rotenone have been determined to be activated. The mechanisms of the influence of the cholic
Strangulation colic often leads to surgery. We aimed to document the molecular response in the non-resected intestine in these horses using quantitative Western blot analysis, and immunohistochemistry. The expression of hypoxia-inducible factor 1-alpha (HIF1α) was investigated together with two
This study aimed to evaluate the reliability of slaughterhouse-obtained small intestinal tissue as control material in equine colic research where molecular stress responses in small intestinal tissue are investigated. For this purpose, small intestinal samples from colic horses were collected
The purpose of this study was to test the hypothesis that horses with proximal enteritis (PE) are predisposed to hepatic injury. We also determined whether the presence of liver injury in horses with PE was associated with other clinicopathologic abnormalities or affected outcome. The medical
