“…The tongue exhibits a lining or rather a continuous mucous of different thicknesses, throughout its surface. The epithelium is thick and rigid on the dorsal surface where tongue wear is greater due to friction with food [ 3 ]. The ultrastructural elements of the epithelium vary in the morphology of different mammals and show several types of papillae.…”

The aim of the present study was to describe the tridimensional morphological characteristics of the lingual papillae and their connective tissue cores (CTCs) in Sprague Dawley rats. Four types of papillae were reported on the dorsal surface. Filiform papillae were distributed on the tongue surface and after epithelial maceration a conic and multifilamentary shape of the CTCs was revealed. Fungiform papillae were reported on the rostral and middle regions covered by a squamous epithelium. After the removal of the epithelium, the shape of a volcano with the taste orifice at its top was noted. Foliate papillae were composed of five pairs of epithelial folds situated on the lateral-caudal margin of the tongue. After the removal of the epithelium, they were shown to be limited by thin laminar projections. The vallate papilla with an oval shape was present in the caudal region and delimited by an incomplete groove. The morphological characteristics of the lingual papillae of Sprague Dowley rats, three-dimensional SEM images, and the types of papillae on the dorsal surface were similar to those reported previously in other rodent mammals. The maceration technique revealed the details of extracellular matrix with varied shapes form of connective tissue cores.

“…The epithelium is thick and tough on the dorsal surface where tongue wear is greater due to friction with food. 11 The ultra structural elements of the epithelium vary in the morphology of different mammals and show several types of papillae. Besides being associated with animal species, variations may be also related to type of food and to the animal's adaptation to environmental conditions.…”

IntroductionMost treatments used to kill cancer cells also kill a diverse range of normal cell types, leading to a broad range of adverse side effects like mucositis. Mucositis is inflammation of the mucous membrane, and it is commonly seen in radiation therapy as well as a patient receiving chemotherapy, the incidence varies according to the type of cancer and treatment modality. 1 It affect about 40 -80% of patients treated with chemotherapy and almost all those receiving radiotherapy of the head and neck. 2 5-Flurouracil in general used for treatment of malignant tumors, particularly of the breast, rectum or colon and in the treatment of uterine, primary hepatic, pancreatic, gastric, ovarian, and bladder carcinomas. The 5-FU is one of the most common causes of oral mucositis 4 , and due to its structure, 5-FU interferes with nucleoside metabolism and can be integrated into DNA and RNA, leading to cytotoxicity and cell death. 3 Oral mucositis may results in discontinuation of chemotherapy or unplanned treatment. [4][5][6] One of the widely used herbs for medicinal purposes is Background and objective: Chamomile has been used as an herbal medication since ancient times and is still popular until today. This study aimed to investigate the potential anticytotoxic effect of chamomile extract on the lingual mucosa of rabbits treated with 5-fluorouracil (5-FU). Methods: Thirty six rabbits were used in the study. For induction of tongue mucositis for the study group, 5-FU at a dose of (4 mg/kg) was administered intraperitoneally one time daily for five successive days. The control animals were intraperitoneally injected by normal saline one time daily for five successive days. The rats in each group were randomly divided into two groups: Distilled water and chamomile extract treated groups (9 animals each). A volume of distilled water equal to chamomile extract was given by gavage tube, while the other group was gavaged with chamomile extract at a dose of (100 mg/ kg) one time daily. The treatment with distilled water or the chamomile extract was continued for sixteen days and then the animals were sacrificed, and the tongues were excised for histopathological and immunohistochemical analysis. Results:The 5-FU/water treated group showed a significant increase in histological damage scores, decrease in the ki-67and increase in caspase -3 epithelial immune expression (P <0.05) in comparison with saline/water treated group. The 5-FU/chamomile treated group showed a significant increase in damage score, significant decrease in ki-67 immune expression and significant increase in caspase-3 immune expression (P <0.05) in comparison with 5-FU/water treated group. Conclusion:Chamomile extract at a dose of (100 mg/ kg) one time daily for sixteen days cannot be used for the treatment of oral mucositis. It causes damage to the tissue, decreases proliferation, and increases apoptosis.

“…A a. lingual em vertebrados fornece suprimento sanguíneo para a língua (Silva et al, 2003;Dyce et al, 2010), assim como visto na preguiçacomum. Semelhantemente aos resultados obtidos, Ferreira et al (2011) observaram que a a. lingual de Sus scrofa domestica passa pelo osso hioide e penetra a musculatura extrínseca, atingindo a língua, onde penetra emitindo ramos. Eles também observaram que a a. lingual não fornece ramos apenas para a irrigação da língua, sendo verificados ramos que irrigam regiões subjacentes, sendo esse último caso visto em B. variegatus, onde o Ali emitiu um ramo lateral ascendente que atingiu rostralmente a laringe.…”

RESUMO Bradypus variegatus, espécie pertencente à família Bradypodidae e à superordem Xenarthra, pode ser considerada modelo biológico de caráter multidisciplinar. Assim, realizou-se um trabalho de descrição anatômica da artéria carótida externa (ACE) e dos seus ramos no bicho-preguiça B. variegatus. Utilizaram-se 10 animais adultos, sendo todos fêmeas, que foram submetidos à dissecação, constatando-se que a artéria (a.) carótida comum se bifurca, em externa e interna, no nível do primeiro anel traqueal. A ACE, então, segue estendendo-se até a maxila, onde emite ramos para a região temporal e para o polo posterior do olho. Em todos os animais estudados, foram observados sete ramos principais da ACE, que, segundo a sua origem e localização, foram denominados como a. auricular, a. lingual, a. facial, a. alveolar, a. inferior, a. temporal, a. maxilar e a. oftálmica. Os ramos maxilar e oftálmico correspondem aos terminais e os demais são ramos colaterais. Em 50% dos animais analisados, foi verificada a presença de anastomoses arteriais e 40% deles apresentaram o acréscimo de um ramo aos principais. Desses, 30% demonstraram a presença de um ramo traqueal e 10% de um ramo sublingual, sendo esses ramos colaterais.
