BACKGROUND The purpose of this paper was to present a case series of self-limiting, peripheral acute retinal necrosis and to demonstrate efficacy of treatment with valacyclovir in patients resistant to acyclovir. The diagnosis was made on ophthalmoscopic examination and positive serum tests for herpes viruses. MATERIAL AND METHODS Ten patients (6F and 4M) aged 19-55 years were diagnosed and t...

Tylophora asthmatica is used in the treatment of respiratory diseases. In Ayurveda. Animal studies have demsonated antiasthmatic, anti-allergic, cytotoxic, hepatoprotective and immunomodulator activites of T.asthmatica. Secera clinical trials hev eebn carried out in case of bronchial asthma; however, design of most of these studies is convoluted. The monograph analyses chemistry, pharmacology a...

BACKGROUND Acute retinal necrosis (ARN) is a viral syndrome consisting of uveitis/vitritis, occlusive vasculitis and peripheral necrosis. Few incidents are reported in children. The etiology is reactivated herpes simplex virus (HSV) or varicella-zoster virus (VZV). Treatment with acyclovir is often used. The administration of oral glucocorticosteroids is of unproven benefit. Prognosis is variab...

Oxotrimesityliridium(V), (mes)3Ir=O (mes = 2,4,6-trimethylphenyl), and trimesityliridium(III), (mes)3Ir, undergo extremely rapid degenerate intermetal oxygen atom transfer at room temperature. At low temperatures, the two complexes conproportionate to form (mes)3Ir-O-Ir(mes)3, the 2,6-dimethylphenyl analogue of which has been characterized crystallographically. Variable-temperature NMR measurem...

BACKGROUND Chickenpox is rarely associated with posterior segment inflammation. We report on a case of unilateral chickenpox chorioretinitis with retinal exudates and periphlebitis. CASE PRESENTATION A 21-year-old healthy man, who suffered from chickenpox 2 weeks prior to symptom development, exhibited mild anterior chamber cells, vitreous opacity, sheathing of retinal veins, and yellow-white...

The preparation of a series of homoleptic, four-coordinate lanthanide(ii) complexes, [Ln(Priso)(2)] (Ln = Sm, Eu or Yb) incorporating the bulky guanidinate ligand Priso(-) ([(ArN)(2)CNPr(i)(2)](-), Ar = 2,6-diisopropylphenyl) is described. X-ray crystallography shows the complexes to be isostructural and to exhibit coordination geometries midway between tetrahedral and planar. Comparisons betwe...

Infrared (IR) photodissociation spectra of mass selected Arn-HN2 complexes (n ) 1-13) have been recorded in the 4 μm spectral range in a tandem mass spectrometer. The dominant features are assigned to the ν1 + mνs (m ) 1, 2) combination bands, where ν1 corresponds to the intramolecular N-H stretch mode and νs to the intermolecular stretching vibration of the first (proton-bound) Ar ligand. Syst...

Commiphora berryi (Arn)Englor (Burseraceae) is a well known plant in Tamil nadu, India. It is used in several parts of the state for various medicinal properties. The present work summarizes preliminary phyto chemical study of bark of this plant.

The aim of this work was to study the androgen receptors (AR) expression in pituitary pars distalis (PD) of male viscachas in relation to growth and reproductive cycle. AR were detected by immunocytochemistry and quantified by image analysis. Pituitary glands from fetus, immature, prepubertal, and adult viscachas during their reproductive cycle were used. In the fetal PD, the immunoreactivity (...
