PURPOSE The authors addressed three questions concerning the circadian rhythm of aqueous humor protein concentration in rabbits. First, is there an endogenous oscillator for this circadian rhythm? Second, does a circadian rhythm occur for individual aqueous humor protein components? Third, what is the role of ocular sympathetic nerves, which are more active in the dark phase, in this circadian ...

this study was conducted on 48 specimens of rectus abdominis muscles for recognition and definition of passage and ramification of lower intercostal nerves. the main results of this study are as follows: 1- the seventh and eight intercostal nerves penetrated to posterior layer of the rectus sheath while other intercostal nerves perforated to dorsal layer of internal oblique abdominis aponeurosi...

Glioblastoma developed from cranial nerves are extremely rare. We report the case of a 71-year-old woman with glioblastoma arising both trigeminal root entry zones and Internal Auditory Canal (IAC) nerves.

Heerfordt's syndrome (HS) consists in its complete form of uveitis, parotid or salivary gland enlargement and cranial nerve palsy. The objective of the present study was to analyse if there are also links between HLA-DRB1* alleles and HS, as it is a specific phenotype of sarcoidosis. 1,000 patients with sarcoidosis, out of whom 83 had symptoms associated with HS, were included in the study toge...

Background and objective:Many biochemical features of sulfur mustard (SM) intoxication remained unknown. So far, the direct association between biochemical parameter changes and ocular problems in patients exposed to SM is not evaluated.The current study aimed at evaluating the associations between the ocular findings in patients with SM intoxication and the changes of...

Objective: Alteration in the basement membrane proteins maybe associated with diabetic neuropathy. Fibronectin is one of the most important components of peripheral nerves basement membrane. In this study we investigated the effects of insulin administration on prevention of alteration in fibronectin contents of sciatic nerve in diabetic rats. Materials and Methods: Twenty-four wistar rats wer...
