An initial investigation of dental morphology variation among three southern Naga ethnic groups of Northeast India.

Objectives: This study examines dental morphology trait prevalence among three southern Naga groups and compares them to 10 ethnic groups from other regions of South Asia to accomplish two objectives: assess the biological relationship of these Tibeto-Burman-speakers to speakers of non-Tibeto-Burman languages in other South Asian regions, and determine which traits distinguish northeast Indians from other South Asians.

Methods: Dental morphology traits were scored with the Arizona State University Dental Anthropology System. Tooth-trait combinations were evaluated for significant inter-trait correlation and intra-trait correspondence within dental fields.

Oral administration of diazepam and promazine hydrochloride to immobilize pronghorn.

Oral tranquilizers were mixed with a grain bait and fed to pronghorn (Antilocapra americana) in an attempt to immobilize and thus facilitate their capture. Diazepam, administered at 6 mg/kg body weight immobilized a tame pronghorn fawn within 30 min. Tranquilization was still apparent after 8 h.
