Second branchial cleft cysts are the most common type of branchial abnormalities and usually found high in the neck. Oropharyngeal presence of branchial cleft cyst is very rare. We report a case of oropharyngeal branchial cleft cyst in 2-yr-old girl with about 1 x 1 cm sized cystic mass, which had not any specific symptom. It was removed completely under impression of mucocele and did not have ...

Objective. To find out the incidence of involvement of individual arches, anatomical types of lesions, the age and sex incidence, the site and side of predilection, the common clinical features, the common investigations, treatment, and complications of the different anomalies. Setting. Academic Department of Otolaryngology, Head and Neck Surgery. Design. A 10 year retrospective study. Particip...

Acid-sensing ion channels (ASICs) are epithelial Na(+) channels gated by external H(+). Recently, it has been demonstrated that ASICs play a role in Na(+) uptake in freshwater rainbow trout. Here, we investigate the potential involvement of ASICs in Na(+) transport in another freshwater fish species, the zebrafish (Danio rerio). Using molecular and histological techniques we found that asic gen...

Metrizamide computed tomographic myelography demonstrates well: partial- and full-thickness diastematomyelia; the presence, shape, and (a)symmetry of the two hemicords; focal persistence of two anterior spinal arteries, one supplying each hemicord; the single or double subarachnoid space(s), arachnoid tubes, and dural tubes which encompass the hemicords; the dural septum formed by the medial wa...

The mechanism of Pb-induced disruption of Na(+) and Cl(-) balance was investigated in the freshwater rainbow trout (Oncorhynchus mykiss). Na(+) and Cl(-) influx rates were reduced immediately in the presence of 2.40 +/- 0.24 and 1.25 +/- 0.14 muM Pb, with a small increase in efflux rates occurring after 24-h exposure. Waterborne Pb caused a significant decrease in the maximal rate of Na(+) infl...

1. Techniques for the measurement of unidirectional flux rates in fish which require no anaesthesia or surgery are described. 2. Resting values for Cl- uptake at 10 and 17 degrees C were 8-03 +/- 1-11 and 13-52 +/- 0-95 mu-equiv. 200 g-1 h-1 (+/- S.E.), respectively; and for Na+ the rates were 15-49 +/- 0-40 and 26-30 +/- 0-36, respectively. 3. Hypercapnic acidosis caused an increase in Na+ upt...

The aim of the present review is to summarize the knowledge on the neuroendocrine control of Growth hormone (GH). The biological actions of growth hormone are pleiotropic, including growth promotion, energy mobilization, gonadal development, appetite, social behavior, osmoregulation and control of immune system. Accordingly, the regulatory network for GH is complex and includes many endocrine a...

The genus Heterodera consists of 80 valid species which are distributed all over the world and they range from mono to polyphagous (Subotin et al., 2010). Several species are considered economically important (or quarantine), including H. humuli Filipjev, 1934. Previous studies on H. humuli or H. humuli as a vector of plant viruses were focused on its geographical distribution, biology, life cy...

CASE REPORT We present a case of plateau iris and glaucoma due to multiple unilateral iridociliary cysts. The patient was treated with iridotomy Nd: YAG laser and 360° iridoplasty, without achieving pressure control. Phacoemulsification improved the hypertension. Dynamic gonioscopy and OCT of the anterior chamber was also performed before and after treatment. DISCUSSION Iridociliary cysts are...

The secondary cysts of the fish pathogen oomycete Saprolegnia parasitica possess bundles of long hooked hairs that are characteristic to this economically important pathogenic species. Few studies have been carried out on elucidating their specific role in the S. parasitica life cycle and the role they may have in the infection process. We show here their function by employing several strategie...
