Non-surgical treatment of canine oral malignant melanoma: A case study of the application of complementary alternative medicine.

This report describes a dog with a clinical stage III oral malignant melanoma that was treated with complementary alternative medicine (CAM). The CAM included high temperature hyperthermia, dendritic cell therapy and lupeol injections. Surgery, radiation and chemotherapy were not performed. Two months after the start of treatment, the tumor disappeared and after six months, the follow-up examinations revealed no recurrence or metastasis of the tumor. Quality of life (QOL) of the dog was maintained; therefore, the application of CAM may be an effective treatment for canine oral malignant melanoma. The effective application of CAM has the potential to prolong life and maintain an excellent QOL for pets.

Photodynamic hyperthermal chemotherapy with indocyanine green: a novel cancer therapy for 16 cases of malignant soft tissue sarcoma.

Sixteen cases of malignant soft tissue sarcoma (STS; 10 canines and six felines) were treated with a novel triple therapy that combined photodynamic therapy, hyperthermia using indocyanine green with a broadband light source, and local chemotherapy after surgical tumor resection. This triple therapy was called photodynamic hyperthermal chemotherapy (PHCT). In all cases, the surgical margin was insufficient. In one feline case, PHCT was performed without surgical resection. PHCT was performed over an interval of 1 to 2 weeks and was repeated three to 21 times. No severe side effects, including severe skin burns, necrosis, or skin suture rupture, were observed in any of the animals. No disease recurrence was observed in seven out of 10 (70.0%) dogs and three out of six (50.0%) cats over the follow-up periods ranging from 238 to 1901 days. These results suggest that PHCT decreases the risk of STS recurrence. PHCT should therefore be considered an adjuvant therapy for treating companion animals with STS in veterinary medicine.

Suppressive effects of N-acetyl-D-glucosamine on rheumatoid arthritis mouse models.

We examined effects of N-acetyl-D: -glucosamine (GlcNAc) on rheumatoid arthritis (RA) mouse models and effects of GlcNAc and glucosamine hydrochloride (GlcN) on several serum cytokine productions in RA mouse models. SKG/jcl mice were divided into control, GlcNAc, and GlcN groups. For 56 days, the control group received normal food, the GlcNAc group received 0.5 % GlcNAc-containing food, and the GlcN group received 0.5 % GlcN-containing food. GlcNAc and GlcN equally suppressed arthritis scores and histopathological scores compared to the control group. In the GlcN group, serum tumor necrosis factor-α and interleukin (IL)-6 concentrations were significantly decreased compared to the control group. In the GlcNAc group, serum IL-10, transforming growth factor ß-1, and IL-2 concentrations were significantly increased compared to the control group. Our results indicated that GlcNAc also has suppressive effects on experimental RA in mouse models. The results of serum cytokine concentrations suggested that compared to GlcN, GlcNAc has a different suppressive mechanism in experimental RA models.
