METHODS
Basic animal research.
OBJECTIVE
Cervical spondylotic myelopathy is a common condition among elderly and often treated by surgery. To explore possibility of pharmacologic treatment, limaprost alfadex, a prostaglandin E1 derivative with vasodilatory and antiplatelet action, was tried in a rat
Nerve ischemia induces wallerian degeneration and peripheral neuropathy, the nerve constriction injury induces thermal hyperesthesia. Nerve ischemia is one possible mechanism in the development of thermal hyperesthesia in the nerve constriction injury model. Prostaglandin E1 increases tissue blood
OBJECTIVE
High blood flow induces neointimal atrophy in polytetrafluoroethylene (PTFE) aortoiliac grafts and a tight external PTFE wrap of the iliac artery induces medial atrophy. In both nonhuman primate models, atrophy with loss of smooth muscle cells and extracellular matrix (ECM) begins at ≤4
Ram semen contains high concentrations of PGE1, PGE2, 20-hydroxy-PGE1, and 20-hydroxy-PGE2, which mainly originate from the ram seminal vesicles. The 20-hydroxy-PGE compounds are formed by a tentatively identified cytochrome P450, designated PGE2 20-hydroxylase. Our aim was to clone the enzyme and
Prostaglandin E1 (PGE1) is commonly used in therapy for obstructive diseases, including ischemic retinopathy, in which pathogenetic reactive oxygen intermediates are responsible. However, the mechanism(s) of PGE1 in reducing tissue damage is still unclear. Adult T-cell leukemia-derived factor/human
Reactive oxygen species (ROS) have the potential to damage cellular components, such as protein, resulting in loss of function and structural alteration of proteins. The oxidative process affects a variety of side amino acid groups, some of which are converted to carbonyl compounds. We have
Fibrotic remodelling of the testicular tubular wall is common in human male infertility caused by impaired spermatogenesis. We hypothesized that this morphological change bears witness of an underlying fundamentally altered state of the cells building this wall, that is, peritubular smooth
BACKGROUND
Topical travoprost, a prostaglandin F(2alpha) (PGF(2alpha)) analog, has several well-known side effects, including a darkening of the eyelid and eyelash hypertrichosis, but there are no reports of a deepening of the eyelid superior sulcus associated with its use.
METHODS
We examined one
The precise function of activated microglia and their secretory products remains controversial. In order to assess the role of microglial secretion products, we established an in vitro model of an inflammatory reaction in the brain by co-culturing microglial and neuronal cell lines. Upon stimulation
Of 13 patients with Friedreich's ataxia (Type Ia) and 17 with type IIa recessive ataxias, all were found to have levels of "free erythrocyte protoporphyrin" (FEP) above the normal range. The rise in FEP in Friedreich's ataxia correlated well with the age of the individual and thus appears to be
OBJECTIVE
To evaluate the impact of an abnormal fetal cardiac scan on the management of the pregnancy and the outcome of the newborn.
METHODS
We reviewed all pregnancies that were referred to the Fetal Cardiac Unit for assessment to determine if the finding of a cardiac abnormality influenced the
1. The bovine isolated sphincter pupillae incubated in Krebs solution releases a biologically active substance tentatively identified as prostaglandin E(2).2. The prostaglandin did not appear to be of neural origin or to result merely from tissue degeneration.3. The spontaneous release of
Cyclosporin A toxicity on pancreatic B-cells and its prevention by rioprostil, a prostaglandin E1 analogue, were studied in the model of the isolated perfused pancreas of rats treated with both compounds for 8 days. At toxic doses of cyclosporin (10 and 20 mg/kg b.wt), the B-cells showed severe
A 70-year-old woman presented to our practice with profound ptosis of the left upper eyelid and notable asymmetry of the periocular area. On examination, she was noted to have significant atrophy of the periocular tissues on the left side, with lower eyelid retraction. These features were present
The purpose of this study was to determine whether intravaginal prostaglandin F2 alpha (PGF2 alpha) would be effective for the treatment of metritis or pyometra in the bitch. Seventeen bitches with metritis or pyometra were treated with PGF2 alpha. Prostaglandin F2 alpha (150 micrograms/kg body
