The presence of the aril (sarcotesta) in the papaya causes a slow and low germination, being necessary to break the state of dormancy. Calcium hydroxide that was applied in order to evaluate its scarifying effect was the objective. The sample consisted of 60 randomly selected fruits of hermaphrodite plants in a commercial production batch of approximately 1 ha (2222 plants) showing commercial maturity, of homogeneous size (±2 kg). The treatments were calcium hydroxide Ca(OH) 2 at three doses, dipping the seed for a period of 24 h; the standardized sodium hydroxide (NaOH) at 25% with a 15 min immersion time. The highest germination and vigor seeds were obtained applied Ca(OH) 2 with highly significant differences respect to the rest treatment, especially for the dose of 60 g l −1 of water for reasons of diminishing expenses. Significant correlations were found, with direct relations (aril and mechanical damage) and inverse relations (abnormal seeds) between the variables evaluated related to the vigor and germination of the seeds. It can be an ecological and not expensive methodology to improve the germination and vigor of papaya seeds in relation to other chemical compounds to scarify.
Angina de Ludwig é descrita como um grave processo infeccioso- inflamatório, com evolução de natureza rápida e polimicrobiana, que acomete os espaços Peri mandibulares, podendo se disseminar e causar altas taxas de morbidade e mortalidade. A origem odontogênica está entre as mais freqüentes etiologias para o surgimento dessa infecção e caracteriza-a como um importante problema de saúde pública, tendo em vista sua prevalência e consequências. O objetivo deste trabalho é relatar um caso clínico de Angina de Ludwig de causa odontogênica na qual uma paciente do gênero feminino, apresentava assimetria facial, edema endurecido à palpação nos espaços submandibulares direito e esquerdo e submental, a qual possuía os dentes 37 e 38 com extensa destruição coronária, devido a evolução de processo carioso. Dessa maneira, faz-se necessário a intervenção do cirurgião-dentista especializado na área de Cirurgia Bucomaxilofacial, levando em consideração ser o profissional apto a conduzir o protocolo de atendimento mais eficaz, com alta resolução e bom prognóstico em casos como esse.
