Inhalation therapy with M1 inhibits experimental melanoma development and metastases in mice.

Background: M1 is a homeopathic medicine with immunostimulatory properties used mainly by cancer patients to complement current therapies. Metastatic melanoma is a skin-originated form of cancer without a single therapy able to produce high rate and sustained responses, which attracts the use of complementary therapies such as M1. However, M1's anti-melanoma effects remain to be pre-clinically demonstrated.

Bax/Bcl-2 protein expression ratio and leukocyte function are related to reduction of Walker-256 tumor growth after β-hydroxy-β-methylbutyrate (HMB) administration in Wistar rats.

This study investigated the mechanisms by which β-hydroxy-β-methylbutyrate (HMB) administration in rats reduces Walker-256 tumor growth. Male Wistar rats were supplemented with HMB (76 mg/kg/day) (HW), or a placebo (W), during 8 wk by gavage. At the 6th wk, rats were inoculated with a suspension of Walker 256 tumor cells (3 × 10(7)/mL).

Mercurius solubilis: actions on macrophages.

Background: Macrophages play central roles in homeostasis as well as host defence in innate and acquired immunity, auto-immunity and immunopathology. Our research group has demonstrated the effects of highly diluted toxic substances in macrophages.

Aim: To investigate if highly diluted Mercurius solubilis (Merc sol), can activate or modulate macrophage functions.

B1 and B2 kinin receptor participation in hyperproliferative and inflammatory skin processes in mice.

Background: Kinins are released during dermal injury and inflammation and seem to contribute to the pathogenesis of cutaneous diseases.

Objective: Participation of kinins in skin inflammatory process was evaluated using knockout mice and non-peptide kinin receptor antagonists.

Methods: Chronic skin inflammation was induced by multiple applications of TPA in mice ear.
