  • Chitosan with small content in the feed (0.48 - 0.75%) could be selected to prepare shrimp feed-pellet having so high water-stability that met the Standard of Vietnam Ministry of Fisheries 28-TCN 102/1997. The radiation treatment at sterilization doses (20 - 30 kGy) was evaluated as the most practical technology because irradiated chitosan with reduced content of 0.34% has capacity to be prepared feed-pellets as stable as comparable to imported products.

  • Photodynamic treatment (PDT) is an emerging therapeutic procedure for the management of cancer, based on the use of photosensitizers, compounds that generate highly reactive oxygen species (ROS) on irradiation with visible light. The ROS generated may oxidize a variety of bio-molecules within the cell, loaded with a photosensitizer. The high reactivity of these ROS restricts their radius of action to 5–20 nm from the site of their generation.

  • Among the subspecialties of internal medicine, medical oncology may have had the greatest impact in changing the practice of medicine in the past four decades, as curative treatments have been identified for a number of previously fatal malignancies such as testicular cancer, lymphomas, and leukemia. New drugs have entered clinical use for disease presentations previously either untreatable or amenable to only local means of therapy, such as surgery and irradiation.

  • Science of brachytherapy is currently increasing in the field of cancer therapy. By virtue of the development of computer assisted technologies, we can reap the benefits of accurate radiotherapies more than ever, which enabled precise irradiation to a target safely avoiding unnecessary involvement of the surrounding normal tissue. Unlike teleradiotherapy provided by X-ray linear accelerator, brachytherapy utilizes radiation source placing inside or close to the target.

  • Melanoma and Other Tumors Melanoma is the most common primary tumor of the eye (Fig. 29-18). It causes photopsia, an enlarging scotoma, and loss of vision. A small melanoma is often difficult to differentiate from a benign choroidal nevus. Serial examinations are required to document a malignant pattern of growth. Treatment of melanoma is controversial. Options include enucleation, local resection, and irradiation. Metastatic tumors to the eye outnumber primary tumors. Breast and lung carcinoma have a special propensity to spread to the choroid or iris.

  • Recent introduction of PSA into the health check up program in Japan resulted in a marked increase of patients with early stage prostate cancer. These patients were treated until now by open or laparoscopic prostatectomy, irradiation therapy including external beam irradiation and brachytherapy, hormonal therapy, watchful waiting and high intensity focused ultrasound.

  • Breast Cancer: Treatment Primary Breast Cancer Breast-conserving treatments, consisting of the removal of the primary tumor by some form of lumpectomy with or without irradiating the breast, result in a survival that is as good as (or slightly superior to) that after extensive surgical procedures, such as mastectomy or modified radical mastectomy, with or without further irradiation. Postlumpectomy breast irradiation greatly reduces the risk of recurrence in the breast.

  • Rare patients with localized early stage mycosis fungoides can be cured with radiotherapy, often total-skin electron beam irradiation. More advanced disease has been treated with topical glucocorticoids, topical nitrogen mustard, phototherapy, psoralen with ultraviolet A (PUVA), electron beam radiation, interferon, antibodies, fusion toxins, and systemic cytotoxic therapy. Unfortunately, these treatments are palliative. Adult T Cell Lymphoma/Leukemia Adult T cell lymphoma/leukemia is one manifestation of infection by the HTLV-I retrovirus.
