In the previous review, the physical aspect of heavy particles, with a focus on the carbon beam was introduced. Particle beam therapy has many potential advantages for cancer treatment without increasing severe side effects in normal tissue, these kinds of radiation have different biologic characteristics and have advantages over using conventional photon beam radiation during treatment. The relative biological effectiveness (RBE) is used for many biological, clinical endpoints among different radiation types and is the only convenient way to transfer the clinical experience in radiotherapy with photons to another type of radiation therapy. However, the RBE varies dependent on the energy of the beam, the fractionation, cell types, oxygenation status, and the biological endpoint studied. Thus this review describes the concerns about RBE related to particle beam to increase interests of the Korean radiation oncologists' society.

?With the deepening study of quercetin, some studies show that quercetin can protect lens, with pharmacological activities such as antioxidation and anti-apoptosis and so on. And they can delay the occurring and developing of cataract. The development and utilization of the quercetin will be expected to be a new means of prevention and treatment of cataract. The article takes in the research progress of that quercetin on the lens with antioxidation, inhibiting aldose reductase and anti- apoptosis and its mechanisms.

Angiogenesis is a critical factor in the progression of solid tumors, including cervical cancers. The mechanisms responsible for angiogenesis in uterine cervical neoplasia are not well defined. To determine the relationship between angiogenesis and the expression of vascular endothelial growth factor (VEGF) in the cervical neoplasia, the author studied 63 cases of the cervical neoplasia diagnosed between the years 1993 to 1997 at Pusan National University Hospital. The expression of VEGF was semiquantitatively analyzed in paraffin sections by immunohistochemical method. Histologic sections immunostained for factor VIII-related antigen were evaluated for microvessel density. Increased expression of VEGF and microvessel counts was significantly correlated with depth of invasion. Increased microvessel counts were also significantly associated with increased VEGF expression. These results suggest that VEGF is an important angiogenic factor and associated with progression of the cervical neoplasia.

The predictive accuracy of the SRK II, SRK/T and Holladay formulas was evaluated in 22 eyes with sever myopia who had phacoemulsification and implantaton of posterior chamber IOL without suture. These patients were followed up for at least 6 months postoperatively. Correlation coefficient between the predicted refraction and actual refraction was 0.57(P<0.01) in the eyes using the SRK/T, 0.566(P<0.01) in the Holladay and (0.06(P=0.791) in the SRK II. The mean absolute error in the SRK/T 0.85 was smaller than that of the Holladay 1.04 and the SRK II1.08(p<0.05). The percentage of the eyes with absolute error within 1D was 68% in the SRK/T, 68% in the Holladay and 53% in the SRK II, but there was no statistically significant difference between them(p>0.05). The percentage of the eye with hyperopic shift(more hyperopic actual refraction than the predicted refraction) was 77% in the SRK II, 77% in the SRK/T and 86% in the Holladay, but there was no statistically significant difference between each formula(p>0.05). In conclusion, the SRK/T has the better predictive accuracy than the SRK II and Holladay in severe myopia and hyperopic shift tends to occur with the application of all three formulas.
