Complete mitochondrial genome sequence and mutations of the rhinosinusitis model inbred C57BL/6 mice strain.

In the present work, we undertook the complete mitochondrial genome sequencing of an important rhinosinusitis model inbred rat strain for the first time. The total length of the mitogenome was 16,308 bp. It harbored 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 non-coding control region (D-loop region).

[Application of chlorophyll in the cervical lymph nodes dissection of laryngeal and hypopharyngeal carcinomas].

Objective: To investigate the patterns of cervical lymph node metastases from the carcinomas of larynx and hypopharynx.

Method: Chlorophyll solution was injected submucosally into some portions of the larynx and hypopharynx preoperately as a stain of lymphatic system to help conduct modified neck dissections in 50 patiants with laryngeal or hypopharyngeal carcinomas. Searial sections were performed.
