We report a case of advanced grades of bleeding hemorrhoids in a 10-yrs-old boy, who had a history of bleeding per rectum since he was 5 year of age. The diagnosis was made on anoscopic examination after ruling out other colorectal pathologies by a full-length colonoscopy. There was no evidence of portal hypertension. He was successfully treated with radiofrequency ablation and plication of hem...

testosterone level was determined in six different populations of iran using saliva steroid assay. significant difference was observed in morning and afternoon testosterone level of the same individual (p>0.00l) significant difference was also noticed among different regions studied (p>0.00 1). comparisons between alcoholics and nonalcoholic as well as smokers and nonsmokers showed significant ...

Salivary duct obstruction secondary to calculi is a common disorder of the submandibular gland and often manifesting as painful episodic swelling of the gland during meals. Complications may arise in unresolved obstruction leading to infections, abscess formation and a hypofunctioning gland.

In 1948 Ellman and Ball drew attention to the pulmonary manifestations of rheumatoid arthritis.' Nevertheless, until recently little attention has been paid to the possibility of pulmonary dysfunction in an appreciable proportion of patients, despite a normal chest x-ray result.2 The reported incidence of pulmonary involvement in rheumatoid arthritis shows considerable variation, ranging from 1...

Alzheimer’s Disease (AD), a slowly progressive neuropsychiatric illness, principally characterized by memory deficits, has become the fourth leading cause of death in developed nations. Since the patients with AD suffer from marked reduction of cholinergic neuronal function resulting in a deficiency in acetylcholine (ACh) concentration in the brain, and these reductions are associated with impa...

Thiols play vital roles in cellular metabolism knowledge of which may be important the design future anticancer drugs. Previous work on composition thiols present human cancer cell lines has shown presence an unknown low molecular weight species, deemed to a “Conthiol”, could this respect. This was prepared and isolated from prostate line (LNCaP) form adduct 2-mercuri-4-nitrophenol; it accounts...

background and objectives: numerous procedures in biology and medicine require the counting of cells. direct enumer- ation of colony forming units (cfus) is time-consuming and dreary accurate cell counting on plates with high numbers of cfus is error prone. in this study we report a new indirect cell counting method that was developed based on the use of redsafe fluorometric assay. the usefulne...

PURPOSE Lingual suspension (LS) and tongue base radio frequency volume reduction (RFVR) have been proposed as means of correcting the obstruction caused by the collapse or hypertrophy of the tongue base in patients having sleep-disordered breathing (SDB). The aim of this study was to evaluate and compare long-term results (6 months and 2 years) in a population of 24 patients having mild obstruc...
