The effects of cholinergic agents on hormone-stimulated cyclic AMP (cAMP) accumulation were investigated in iris-ciliary body segments, excised ciliary processes, and isolated ciliary epithelium from albino rabbit eyes. In all three tissue preparations, the cholinergic agonist carbamylcholine markedly inhibited the stimulation of cAMP biosynthesis by vasoactive intestinal peptide VIP--a potent ...

We investigated the effect of hyperthyroidism on the responsiveness of the rabbit corpus cavernosum smooth muscle. In male albino rabbits, hyperthyroidism was established by oral feeding of L-thyroxine at increasing dosages (150-450 microg/kg) over an 8-week period. This treatment produced a stable hyperthyroid state as indicated by the increased serum T4 levels. The reactivity of corpus cavern...

The authors investigated the effect of liposome encapsulation on the pharmacokinetics of gentamicin after intravitreal injection in albino rabbits, using immunofluorescent assay. Gentamicin was encapsulated into liposomes of phosphatidylcholine, phosphatidic acid, and alpha-tocopherol. The final liposomal suspension contained gentamicin, 10 mg/ml, 95% encapsulated. One eye of each rabbit receiv...

Previous comparative studies of green, albino, and variegated plants have shown higher levels of soluble nitrogenous compounds and lower levels of protein nitrogen in albino or in variegated than in green tissues (6, 14). The soluble nitrogen level was reduced and the protein level was increased when carbohydrates were supplied to albino tissues and plants. Groner (6), on the basis of such find...

Methods. Seventy albino (New Zealand white) rabbit eyes were exposed to UVB radiation in vivo. Fluence of radiation at the cornea was 2.8J/cm, 5.6J/cm, or 11.2 J/cm. Eyes were examined 24 hours after UVB exposure and for as long as 10 days by slit lamp biomicroscopy. Mass spectrometry was used to measure PGE2, PGF^, and 6-keto-PGF,a content of the lens and iris-ciliary body using authentic stan...

Behavioral measurements on the water maze show night blindness in albino mice but cortical recordings show no difference between pigmented and congenic albino mice. Consequently we have measured the absolute threshold in albino and pigmented mice using an operant method. The estimated threshold value is -5.3 log cd/m2 for albino mice and -5.5 log cd/m2 for the pigmented mice. We conclude that t...

background: this study was carried out to observe the radioprotective effects of rosemarinus officinalis leaves extract (roe) against radiation-induced histopathological alterations in liver of mice. materials and methods: adult swiss albino mice were exposed to 6 gy gamma radiation in the presence (experimental) or absence (control) of roe to study the qualitative and quantitative alterations ...

Rabbit is one of the intangible cultural heritages in Beijing, but with popularity modern smart products, it gradually fading from public’s view. In order to better protect and help rabbit master solve problem dying out, this paper will analyze its connotation, artistic characteristics other perspectives, propose new inheritance protection strategies, including: application technology create “R...

Aim of the present study was to evaluate by transmission electron microscope (TEM) modifications in rabbit kidney-parenchyma after submission to ultrasound contrast agent (UCA) with Pulse Inversion Harmonic Imaging (PIHI). Seven inbred male albino rabbits were divided into three groups: 1) control group (n = 1 animal); 2) sonicated group (n = 3 animals); 3) sonicated group with UCA injection (C...

OBJECTIVE To determine the efficacy of 0.5-mg and 0.1-mg sustained-release fluocinolone acetonide intravitreal implants to inhibit ocular inflammation in a rabbit model of severe uveitis. METHODS The in vitro pharmacokinetic profile of both the 0.5-mg and 0.1-mg sustained-release fluocinolone intravitreal implants was determined during a 10-day period. A sustained-release fluocinolone acetoni...
