background: amiodarone is a drug that is used for treatment of cardiac arrhythmia after cardiac ischemia. this drug as b blocker decreases arrhythmia rate but it has many side effects on different tissues. since there are rare reports about changes of lacrimal glands, this research has been carried out to study the morphological and ultrastructural changes of lacrimal gland cells after amiodaro...

in this research, morphology and histology of the left and right lacrimal glands of ten adult ostrich were carefully studied. after the topographical study of the glands and measuring the dimension of them, tissue sections were prepared and stained by current histology. results revealed that in ostrich, lacrimal gland was dark brown to black color and was located obliquely in dorsolateral part ...

PURPOSE The objectives of this investigation were threefold: to advance understanding of the nature and impact of herpesvirus infection in the lacrimal gland; to determine the influence of gender and sex hormones on viral infectivity and replication capacity in lacrimal tissue; and to compare the susceptibilities of lacrimal, submandibular, and parotid cells to viral invasion. METHODS Acinar ...

PURPOSE To study the glycoconjugates in the lacrimal sac epithelium of Japanese white rabbits with experimentally induced chronic dacryocystitis. METHODS Chronic dacryocystitis was induced by a subcutaneous injection of albumin followed by an injection of Staphylococcus aureus into the lacrimal sac. The histological appearance of the lacrimal sac was studied using the alcian blue-periodic aci...

Sjögren syndrome is an autoimmune disease characterized by targeted destruction of the lacrimal and salivary glands resulting in symptoms of severe ocular and oral dryness. Despite its prevalence, the mechanisms driving autoimmune manifestations are unclear. In patients and in the nonobese diabetic (NOD) mouse model of Sjögren syndrome, lymphocytic infiltrates consist of CD4 and CD8 T cells, al...

Linear compartmental analysis was applied to lacrimal scintigraphy data from asymptomatic and obstructed lacrimal systems. Failure to achieve satisfactory results in most of the asymptomatic systems studied suggests that variable tear flow is a feature of normal lacrimal drainage which precludes linear analysis. However, in cases where the analysis was successful the results were consistent wit...

BACKGROUND We analyzed local control and early ocular toxicity after eye-sparing management of lacrimal gland carcinoma. METHODS For consecutive patients with lacrimal gland carcinoma treated during 2007 to 2014, we reviewed tumor characteristics, treatment details, ocular toxic effects, and recurrence. RESULTS Twenty patients, median age 55 years, were treated for lacrimal gland carcinoma ...

The lacrimal gland secretes tear fluids to ocular surface, which plays an indispensable role in maintaining the health of the ocular epithelia and protecting the ocular surface from the external environment. The dysfunction of the lacrimal glands causes dry eye disease due to a reduction in tear volume. The dry eye disease is becoming a popular public disease, for the number of patients is incr...
