Corneal biopsy specimens from 3 patients with Cogan's microcystic corneal dystrophy were examined by light and electron microscopy. Specimens were taken from corneas showing microcysts, geographic or map-like areas, and refractile striae. In all samples there is a bilaminate subepithelial layer of fibrogranular material, the friability of which is probably the basis for recurrent erosions in th...

A 26-year-old man with osteogenesis imperfecta and severe aortic regurgitation was scheduled for aortic valve replacement. As previously described by other authors the operation was difficult owing to the friability and weakness of the tissues. Mean blood losses of 153 mL per hour during the first 7 postoperative hours were observed. Despite normal coagulation indicators the bleeding did not st...

Loratadine, a second generation H1-receptor antagonist, works by blocking the action of histamine and is widely prescribed for itching, runny nose, watery eyes, sneezing from "hay fever" other allergic conditions. To ensure quality main requirements medicinal product are safety, potency, efficacy stability. This research work aimed to compare assess levels different local brands loratadine tabl...

Objective: The goal was to develop a controlled-release formulation of quercetin utilizing the cyclodextrin-based nano-sponges as nanocarrier. Methods: Based on preliminary trials 3-factor, 3-level Box-Behnken design employed. Five types from β-cyclodextrin (NS1-NS5) were purposely designed. Quercetin loaded into by freeze-drying method. prepared characterized and formulated tablets evaluated f...

Objective of this study was to formulate directly compressible orally disintegrating tablets of Cinnarizine with sufficient mechanical integrity, content uniformity, and acceptable palatability to assist patients of any age group for easy administration. Effect of varying concentrations of different superdisintegrants such as Agar, gum karaya, platago ovata on disintegration time was studied. T...

Natural gums are economical, easily available, and useful as tablet binders. In the present investigation, an attempt was made to formulate Ofloxacin tablets using three natural binders, namely Acacia arabica, Hibiscus esculentus, and xanthan gum. Such six batches of Ofloxacin tablets were prepared by using different types and amounts of the natural binders by the wet granulation method. The ta...

Gastrointestinal disturbances, such as nausea and vomiting, are considered amongst the main adverse effects associated with oral anticancer drugs due to their fast release in the gastrointestinal tract (GIT). Sustained release formulations with proper release profiles can overcome some side effects of conventional formulations. The current study was designed to prepare sustained release tablets...

The overall agreement between different criteria for cervicitis in women infected with Chlamydia trachomatis and/or Mycoplasma genitalium, and in women who tested negative was examined. Women attending a clinic for sexually transmitted diseases were enrolled because of sexual partners' suspected chlamydia infection. M. genitalium was tested in a sample of first-catch urine and an endocervical s...

Common variable immunodeficiency (CVID) is a primary immunodeficiency disease characterized by hypogammaglobulinemia and recurrent bacterial infections especially in respiratory and gastrointestinal systems. We present here 2 cases of CVID with gastrointestinal complications.Case 1 is a 25-year-old man with a history of chronic diarrhoea from childhood. Ultrasonography revealed ascites, with li...

The present study was designed to investigate the effect of different types of coating polymers such as Eudragit RL 30D, Eudragit RS 30D, Eudragit NE 30D, Surelease, and Kollicoat SR 30D on physical properties and release pattern of salbutamol sulphate (SS) pellets which were prepared by Extrusion-Spheronization technology. All the polymers used in coating solution were in aqueous dispersion fo...
