  • 135 and 136 pine cones were sampled from age class of II to VI Korean pine trees for the study of their physical properties in 1991 and 1992, respectively. The length, width, weight, volume, and the largest projected area of cones were measured, and the specific gravity, apparent volume ratio sphericity, and roundness were calculated. Regression analysis were performed for the weight, volume, and projected area to the cone length and width. The length, and major and minor diameters of the cone stalks were measured and analyzed. 1. The range of the length of cone stalks was 0 to 47.3mm. The average length of stalks were 9mm ('91) and 10mm('92), respectively. Cross section of the stalks was ellipse with average major and minor diameters of 9.1mm and 10.1mm, and 8.6 and 8.7mm in 91 and 92, respectively. 2. The length of pine cones distributed from 8cm to 17cm and the average length were about 13cm('91, '92). The width varied from 5cm to 9.5cm and the average width were 6.7cm('91) and 6.9cm('92). The ratios of the length to the width were 0.56('91) and 0.65('91) and the shape of the cones were found to be ellipse with minor diameter of 1/2 to 2/3 of the major diameter. 3. The roundnesses and sphericity of cones were 0.74 and 0.75('91), 0.63 and 0.67('92), respectively. The average of the largest projected area of cones were $85.3cm^2$('91) and $93.1cm^2$('92) and the criterion areas were $71.0cm^2$ and $74.5cm^2$, respectively. 4. Cone weights were from 83g to 467g('91 and '92) and averages were 186g('91) and 220g('92). The average specific gravities were 0.89 and 0.96('91 and '92). The true volumes were $212cm^2$('91) and $230cm^2$('92), and the average bulk volume was $321cm^2$('91, '92). The average apparent volume ratios of cones were 35% ('91) and 28% ('92), respectively. 5. The weight and the volume were proportional to the length of the cone multiplied by the width squred and the largest projected area was proportional to the length multiplied by the width of cones.

  • Objectives : I investigated whether Bee Venom can synergistically strengthen the cytotoxic effects of NK-92 cells, enhancing the inhibition of the growth of Lung Cancer Cells including A549 and NCI-H460 through induction of death receptor dependent extrinsic apoptosis and NO generation in the Nitro-oxide pathway. Methods : Bee Venom inhibited cell proliferation of A549 or NCI-H460 Human Lung Cancer Cells as well as NK-92 Cells. Moreover, when they were co-punctured with NK cells and concomitantly treated by 3 ${\mu}g/ml$ of Bee Venom, more influence was exerted on inhibition of proliferation of A549 or NCI-H460 Human Lung Cancer Cells than BV or NK cell co-culture alone. Results : The expression of Fas, TNFR2, DR3, DR6 in A549 Lung Cancer Cells was significantly increased by co-culture of NK-92 cells and treatment of 3 ${\mu}g/ml$ of Bee Venom, compared to co-culture of NK-92 cells alone, whereas the expression of Fas, TNFR2, DR6 in NCI-H460 Lung Cancer Cells was significantly increased by co-culture of NK-92 cells, representing no synergistic effects in the co-culture of NK-92 cell and concomitant treatment of 3 ${\mu}g/ml$ of Bee Venom. Coincidently, caspase-8, a expression of pro-apoptotic proteins in the extrinsic apoptosis pathway demonstrated same results as the above. Meanwhile, In NO generation, there is little change of NO generation in co-culture of NK-92 cells with A549 cells as well as the co-culture of NK-92 cell with them and concomitant treatment of 3 ${\mu}g/ml$ of Bee Venom, whereas increase of NO generation was shown in co-culture of NK-92 cells with NCI-H460 cells as well as the co-culture of NK-92 cell with them and concomitant treatment of 3 ${\mu}g/ml$ of Bee Venom, although synergistic effects by Bee Venom was not found. Conclusions : These present data provide that Bee Venom could be useful candidate compounds to enhance lung cancer growth inhibiting ability of NK-92 cells through DR expression and the related apoptosis.
