Effects of hard water on hair.

Background: Hardness of water is determined by the amount of salts (calcium carbonate [CaCO3] and magnesium sulphate [MgSO4]) present in water. The hardness of the water used for washing hair may cause fragility of hair.

Objective: The objective of the following study is to compare the tensile strength and elasticity of hair treated in hard water and hair treated in distilled water.

Lepromatous leprosy treated with combined chemotherapy and immunotherapy (injection BCG): three case reports.

Background: Lepromatous leprosy is associated with suppressed cell-mediated immunity (CMI). This results in failure of the body to mount an efficient immune response and may render chemotherapy ineffective. The lack of sufficient response may mimic drug resistance.
