Marcus Gunn phenomenon consists of a synkenesis between the masticatory musculature and the levator muscle of the contralateral eyelid. It is seen in patients with congenital ptosis. The phenomenon is normally unilateral, but bilateral cases are not unknown. Its exact etiology is not known. We report a case of bilateral Marcus Gunn phenomenon. The ptosis is secondary to a conflict between the o...

A young man aged 19 yrs had developed symptoms of facial paralysis on the left side 3 months before admission to the Government Ophthalmic Hospital, and had been treated at another hospital, with some improvement. A month after the onset of this facial palsy he developed pain in the abdomen, for which he attended the Government General Hospital, and during the examination the attending medical ...

A model of hopping conductivity is proposed that takes into account the nonlinear dependence of the mobility of the charge carriers on an externally applied field. The latter is known to be the main origin of the creation of high-field domains in n-type polar semiconductors and is responsible there for the current oscillations observed in the so-called Gunn effect. In this paper we study the ef...

In recent years it has repeatedly demonstrated by a number of investigators in various animal species that a single administration of cadmium salt produces a selective damage to the testis (in mice, Meek 1959, Chiquoine 1964; in rats, Pati.zek and Zâhot 1956, Allanson and Deanesly 1962, Kar and Das 1962, Gunn, Gould and Anderson 1961, 1963a,b, Mason, Brown, Young and Nesbit 1964 ; in rabbits, C...

1. Antiserum was raised against purified Wistar-rat liver UDP-glucuronyltransferase. 2. UDP-glucuronyltransferase activities towards 4-nitrophenol, bilirubin, 1-naphthol and morphine were co-immunoprecipitated from solubilized Wistar-rat liver preparations. 3. UDP-glucuronyltransferase activities towards 1-naphthol, 2-aminophenol and 4-nitrophenol were precipitated from solubilized Gunn-rat liv...
