PURPOSE To determine the effect of triple drug immune suppression on RPE xenograft survival in the fetal pig after transplantation into the albino rabbit subretinal space. METHODS Primary RPE microaggregates (approximately 40,000 RPE cells) were injected into the subretinal space of 24 albino rabbits, with half the rabbits maintained on triple systemic immune suppression. RPE survival was est...

The effect of human chorionic gonadotropin (hCG) on the rabbit eye was studied. Intravitreal injections of hCG in albino rabbits provoked a reduction of intraocular pressure (IOP). Intravenous administration of hCG in single doses of 5,000-10,000 units in male pigmented rabbits caused a significant reduction in IOP from 1.5-5 hr after injection. When two successive intravenous doses of 5,000 un...

Antipyretic effects of petroleum ether and ethyl acetate soluble fractions of ethanol extract of the leaves of Peperomia pellucida (Linn.) HBK (Fam. Piperaceae) were investigated. Intraperitoneal administration of boiled milk at a dose of 0.5 ml/kg body weight in albino rabbit leads to pyrexia. Intraperitoneal (i.p.) administration of petroleum ether and ethyl acetate soluble fractions of ethan...

Antipyretic effect of petroleum ether and chloroform soluble fractions of ethanol extract of the roots of Vernonia cinerea was investigated. Intraperitoneal administration of boiled milk at a dose 0.5 ml/kg body weight in albino rabbit leads to pyrexia. Intraperitoneal (i.p. route) administration of petroleum ether and chloroform soluble fractions of ethanol extract of the roots of Vernonia cin...

Tyrosinase is encoded by the Tyr (c or albino) locus and is the key enzyme in pigment biosynthesis. Loss of function of this enzyme caused by gene mutation results in albinism. Most cases of albinism are caused by missense mutations of tyrosinase. Albino mutations in Tyr have been identified in various animals, including human, mouse, rat, rabbit, cattle, cat, and ferret, but not in gerbil. We ...

Desensitization of ocular adrenergic receptors was examined in vivo in albino rabbit eyes. Repeated topical administration of 2.0% l-epinephrine bitartrate (equivalent to 1.1% free base) to the rabbit eye resulted in the loss of ocular hypotensive response on the second day of daily or twice-daily treatment. Concurrent topical administration of dexamethasone phosphate (0.1%) prolonged the press...

Household products, shampoos, pesticides, weed killers, even riot control gases, are just some of the products tested for irritancy in the eyes of conscious rabbits. The Draize test, introduced in 1944, is cruelly simple. The substance under test is sprayed or instilled into one eye of an albino rabbit. Generally no pain relief is given and the test often proceeds for 7 days during which the co...

Disrupting mutations affecting the tyrosinase (TYR) gene cause different forms of albinism in mice, humans and several other mammals. Classical genetic studies have already reported five alleles at European rabbit Albino locus, indicated to be part C series, each them with actions on pheomelanin eumelanin production, as well eye colour. A few these been characterised DNA level by sequencing cod...

The anti-fertility activity of prostaglandin synthesis inhibitors namely the non-steroidal anti-inflammatory drugs: acetyl salicylic acid, indomethacin and oxyphenbutazone were investigated in male and female albino rats and female albino rabbits. Oxyphenbutazone and indomethacin affected the reproductive process in male rats. Indomethacin 3 mg/kg. and acetyl salicylic acid 300 mg/kg produced s...
