ABSTRACT
Background: To provide anatomical information on theposition and incidence of accessory foramina in mandible asthey are important for dental surgeons and anesthetists inachieving complete nerve blocks and for avoiding injury toneurovascular structures passing through them.Objective: To study the incidence of accessory foramina in drymandible in population of Bihar & compare it with incidenceamong various races of the world.Materials & Methods: Present study is a cross sectional studywhich has been carried out on 56 dried fully ossified adulthuman mandibles, which were examined in the Department ofAnatomy and Forensic Medicine of Indira Gandhi Institute ofMedical Sciences, Patna, Bihar. The age of the bones used inthe study was not predetermined. Only fully ossified dried,macerated and thoroughly cleaned mandibles which werecomplete in all respects, in order to give the correctobservations, were included in the study while the mandibleshaving any deformity or pathology were excluded. Theaccessory foramina and their positions were observed.Results: Accessory mandibular foramina were found in 55.36%, accessory mental in 23.22 %, and retromolar in 17.85% ofthe cases. The accessory foramen observed most commonly inright side (39.28%) followed by bilateral (37.5%) then left side(19.65%).Conclusion: The anatomical variability of incidence andposition of accessory foramina should be considered as theymay be used to give additional locoregional anesthesia in caseof failed mandibular blocks. Knowledge of the commonestpositions will be beneficial for oncologists and oromaxillofacialsurgeons in planning graft implants.
ABSTRACT
The study was conducted to screen the antipyretic activity of alcoholic extract of the leaf of Platycladus Orieantalis .Platycladus Orieantalis is a potent medicinal plant in the Indian systems of medicine. Traditionally it is used as a diuretic, anticancer, anticonvulsant, stomachic, antipyretic, analgesic, etc. In the present study the alcoholic extract of the leaf of Platycladus Orieantalis were studied for their antipyretic activity by Brewer’s yeast-induced pyrexia in rats. It was observed that the alcoholic extract produced significant antipyretic activity (p < 0.05). The extract showed marked antipyretic activity in a dose dependent manner.
