Cytotoxic Effect of the Distilled Pine-Needle Extracts on Several Cancer Cell Lines in vitro

솔잎 수액 증류액의 암세포주에 대한 in vitro 세포독성

  • Published : 2002.08.01

Abstract

This study was performed to examine the cytotoxic effects of the distilled pine-needle extracts against several cancer cell lines. First, cell lines including mice leukemic cancer cell line (L1210), sarcoma 180 and human monocyte-like cancer cells (U937) were tested using XTT methods in uitro. Pine-needle extracts were prepared by pressing the pine needles and distilling it at below 98$^{\circ}C$ and then added to the growth medium in a final dilution of 10, 20, and 40 times. Growth of three kinds of cancer cells was significantly inhibited by more than 50% with the addition of the extracts. Fifty six to seventy six % of inhibition was shown with the 40 times dilution of the extracts. Greater inhibition was achieved with the 20 times dilution (81~90%) and the 10 times dilution (77~89%) of the extracts. Next, other human cancer cell lines including 3 kinds of breast cancer cell lines (T47D, MDA-MB-231 and MW7A) and one hepatoma cell line (SNU-354) were tested with the 20 times dilution of the extract. T47D and MDA-MB-231 cell lines showed lower inhibition (12%) with the addition of the extract. However, MH7A and SNU-354 cell lines showed 64% and 72% inhibition with the extract, respectively. These results suggest that the distilled pine-needle extracts have strong cytotoxic effect on certain cancer cell lines and the intensity of the effect may vary depending on the process of the pine needle.

한국산 솔잎을 가압.압착하여 얻은 수액을 증류한 솔잎 수액 증류액의 각종 암세포주에 대한 in uitro 세포독성을 시료액 대비 10배, 20배, 40배 희석군과 대조군에 대해 XTT법으로 실험한 결과, 쥐 백혈병 세포주인 L1210에 대해서는 76~89%, 쥐 육종암세포인 sarcoma 180에 대해서는 61~90%의 세포성장 억제효과를 나타내었다. 또한 인체의 monocyte-like cancer cell인 U937에 대해서는 56~81%, 인체 유방암 세포주인 T47D와 MDA-MB-231에서는 각기 12%, 또 다른 유방암 세포주인 MH7A에서는 64%, 인체 간암 세포주인 SNU-354에 대해서는 72%의 높은 세포 증식 억제효과를 나타내었다. 이로써 본 연구 시료인 솔잎 수액 증류액은 쥐 백혈병 세포주인 L1210, 쥐 육종암세포인 sarcoma 180, 인체 monocyte-like cancer cell인 U937, 인체 유방암 세포주인 MH7A, 인체 간암 세포주인 SNU-354에 대해 강한 세포독성을 갖는 것을 알 수 있었다. 이와 함께 솔잎 수액 증류액의 암세포에 대한 독성효과는 솔잎의 처리과정에 따라 다를 수 있으며, 또한 동일한 솔잎 수액증류액의 농도에서도 암세포주 종류에 따라 세포독성정도가 다름을 알 수 있었다. 따라서 최적 투여 농도와 적용 암세포주를 찾을 경우 새로운 항암제로 개발될 수 있음을 제시하였다.
