The effect of natural killer (NK) cells and lymphokine activated killer ( LAK) cells was studied on a group of human melanoma cell lines. Peripheral blood from healthy volunteers was utilized as a fresh source of natural killer cells and rhI L-2 for producing LAK cells. The cytotoxicity of effector cells was quantified using a 4 hour SI determining the density of antigen expression on tumor...

Melanoma has been reported a contemporary malignant cancer. Here, anti-cancer effects of sea cucumber extract (SCE) have been examined on melanoma cells and compared with dacarbazine. MTT assay and morphological analysis were performed to evaluate cytotoxic effects of methanolic SCE Also, several methods were exerted to detect cell dying by SCE and dacarbazine. The MTT assay showed that B16F10 ...

Introduction In order to treat uveal Melanoma , first, radioactive seeds are laid on a silicone- made substance which is called Silastic after that they are inserted in the plaque, and finally, this plaque containing silicone-made substance is stitched to the sclera surface. The dose gradient within the tumor and healthy tissues can be varied due to changing the Silastic thickness between scler...

Objective(s):Involvement of tyrosinase in the synthesis of melanin and cell signaling pathway has made it an attractive target in the search for therapeutic inhibitors for treatment of different skin hyperpigmentation disorders and melanoma cancers. Materials and Methods: In the present study, we conducted a comprehensive kinetic analysis to understand the mechanisms of inhibition imposed by 2-...

Melanoma is a challenging disease to treat. Punica granatum L. has a potential anticancer effect. This study determined the antiproliferative and antiangiogenic potential of the extract from pomegranate peel (PPE) in melanoma. Melanoma cells (1 × 106) were injected to C57BL6 mice subcutaneously. On 8th day, mice were randomly divided into 9 groups. Group 1 was considered as control and received...

Background: Melanoma is the most serious form of skin cancer and it has the highest rate of growth among different types of cancers. Ursolic acid (UA), a natural pentacyclic triterpenoid, is a major bioactive compound in several traditional medicinal plants including pomegranate (Punica granatum L.) flower. UA has very important biological and pharmacological functions. Objective: In this study...

Skin cancer is usually classified as melanoma and non-melanoma. Melanoma now represents 75% of humans passing away worldwide one the most brutal types cancer. Previously, studies were not mainly focused on feature extraction Melanoma, which caused classification accuracy. However, in this work, Histograms orientation gradients local binary patterns procedures are used to extract important featu...

Background: Malignant melanoma is a highly metastatic cutaneous cancer and typically refractory to chemotherapy. Deregulated apoptosis has been identified as a major cause of cancer drug resistance, and upregulated expression of the inhibitor of apoptosis protein melanom, an inhibitor of apoptosis (ML-IAP) is frequent in melanoma. Methods: Based on the conclusion that ML-IAP expression contribu...

  Introduction: Sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. In Iran, this procedure has not been addressed sufficiently. In this study, we report our experience in this area. Methods: Ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mCi of Tc-99m antimony...
