Abstract:
AIM: To investigate the effects of Chinese medicine, Jinan injection, on ultrastructure and mitochondria in cultured lung cancer cell lines. METHODS: The cultured lung cancer cell lines PG and PAa were used and divided into 4 groups: control (C), cisplatin (DDP), Jinan (JA) and Jinan in combination with cisplatin (DJ), respectively. The changes of morphology and mitochondria membrane potential, intracellular Ca~(2+) and pH in every group were observed by inverted microscope and electronic microscope as well as by using flow cytometry, staining by rhodamine, Fluo-3 and BCECF, respectively. RESULTS: Degeneration cells showed chromatin condensation and peripheral congregation. In cytoplasm autophage lysosome increased and myelinoid body was seen easily. In mitochondria structure, where the space between the inner and outer membranes of these organelles expanded as the matrix was compressed. The electron-dense or swelled was observed as vacuole degeneration and its matrix showed electron-lucent. Compared to control, mitochondria membrane potential increased in every group after 24 h and 48 h treatment. DDP increased intracellular calcium ion in PG cells, however, in PAa cells, JA and DJ decreased it. Intracellular pH got lower at 24 h and higher at 48 h in PG and PAa cells. There were significance in every group vs control in PG and PAa by statistic t-test (P
