Therefore various diseases can be developed by continuous action of estrogen and progesterone. Breast diseases are mainly categorized as benign and malignant. It is very important to distinguish the malignancy from breast diseases.(More)
A new dosage form consisting of small activated carbon particles which adsorb Aclacinomycin A, Adriamycin, Mitomycin C or Pepleomycin was prepared in order to deliver larger amounts of anticancer agents to the lymph nodes through the high ability of lymphatics to adsorb particles. Animal experiments showed that: The LD50 values of the new dosage form were(More)
Cervical cancer is a serious disease that threatens the health of women worldwide. This study compared the sensitivities and false-positive rates of cervical cytology (Pap smear), human papilloma virus (HPV) DNA test, cervicography, first double-combined testing (cervical cytology and HPV DNA test), second double-combined testing (cervical cytology and(More)
OBJECTIVE Photodynamic therapy (PDT) has been used for superficial neoplasms and its usage has been recently extended to deeper lesions. The purpose of this study was to observe whether or not PDT can cure breast cancer in the solid tumor model, and to define the critical point of laser amount for killing the cancer cells. METHODS Twenty four BALB/c mouse(More)
OBJECTIVE This study is to compare the effects of green tea polyphenol (GTP) pre-treatment with those of GTP post-treatment on cisplatin (CP)-induced nephrotoxicity in rat. METHODS Male Sprague-Dawley rats were randomly divided into six groups. Animals in the control group received 0.9% saline (intraperitoneal); animals in the GTP group received 0.9%(More)
The possibility that urinary pepsinogen I is a tumor marker of stomach cancer after total gastrectomy was examined. To decide the cutoff level of urinary pepsinogen I after total gastrectomy, urine samples from 15 patients who had undergone total gastrectomy for stomach cancer in the early or advanced stages and had been free from recurrence for more than 5(More)
► Photodynamic therapy can treat lesions with highly reactive single oxygen. ► CCPDT (Concurrent Chemo Photodynamic Therapy) is defined as PDT with chemotherapy. ► CCPDT can treat larger and deeper lesions than PDT due to PCI concept. ► Complete remission would be possible in uterine cervical cancer by CCPDT. ► Uterine cervix and corpus can be preserved in(More)
PEP-CH is comprised of activated carbon particles that adsorb peplomycin. Mice which were inoculated with 5 x 10(5) MH 134 tumor cells subcutaneously opposite the foot-pad of the left hind paw on day 0, received a subcutaneous injection of peplomycin, 0.25 mg/mouse, in the form of PEP-CH or a peplomycin aqueous solution administered at the foot-pad of the(More)
