The free-living nematodes Eumonhystera borealis n. sp., Sphaerolaimus occidentalis n. sp., and S. gracilis de Man 1876 from Bothnian Bay in the northern Baltic Sea are described and illustrated. Eumonhystera borealis n. sp. differs from other species by its small body size (314-393 mum), narrow body (a = 37-49), and large anterior amphids. In Sphaerolaimus occidentalis n. sp. the amphids are po...

lipoma, a benign tumor of adipose tissue is one of the most common benign neoplasms of the body. however, its occurrence in oral cavity is very rare. it accounts for 1 to 4% of benign neoplasms of mouth affecting predominantly the buccal mucosa, floor of mouth and tongue. we report three cases of intraoral lipoma, two in buccal mucosa and one in labial mucosa. an excisional biopsy was performed...

Haemangioma are common tumors characterize microscopically by proliferation of blood vessels, it is classified histologically into capillary and cavernous haemangioma, it is considered one of the most common soft tissue tumor of the head and neck but it is relatively rare in the oral cavity and uncommonly encountered by clinician. This paper describes 57 year old male patient who complaint of a...

Cancer is a non-communicable disease in which cells of any organ the body grow out control. The subject our research cancer that occurs oral cavity, includes lips, inner lining lips and cheeks called buccal mucosa, teeth, gums, front tongue, floor mouth below hard palate (bony roof mouth).

Lung ventilation in Siren lacertina was studied using X-ray video, measurements of body cavity pressure and electromyography of hypaxial muscles. S. lacertina utilizes a two-stroke buccal pump in which mixing of expired and inspired gas is minimized by partial expansion of the buccal cavity during exhalation and then full expansion after exhalation is complete. Mixing is further reduced by the ...

Focal epithelial hyperplasia or Heck’s disease is a benign, rare viral disease of the oral cavity and is associated with human papillomavirus 13 and 32 (HPV-13 and HPV-32). Most patients are children but adults may also be at risk. Clinically, the patients have multiple small white or pink papules on the mucosal surface of the lips, buccal mucosa and the tongue. In Iran, this disease seems to b...

A novel glandular epithelium lining the infrabuccal cavity and anterior pharynx is described in both workers and queens of the pharaoh's ant Monomorium pharaonis. The infrabuccal cavity, connected with the buccal tube, forms a ventral outgrowth of the anterior pharynx, and as such displays the tegumental lining with a cuticle and an epithelial layer. In its dorsal region, the cavity's epitheliu...

Phospholipase and proteinase production and the ability of adhesion to buccal epithelial cells (BEC) of 112 Candida isolates originated from oral cavity of HIV infected patients and from blood and catheter of intensive care unit patients were investigated. The proteinase production was detected by inoculation into bovine serum albumin (BSA) agar and the phospholipase activity was performed usin...

Objective: Chlorzoxazone (CLZ) is centrally acting skeletal muscle relaxant. It is insoluble in water, so employed for the formation of solid dispersions (SD) as a means to enhance the dissolution rate, and carrier selected was polyethylene glycol 6000 (PEG 6000). Methods: The SDs were prepared by different methods and characterized by in vitro drug release, drug content, fourier transform infr...
