| Lange's test | An obsolete, non-specific test for altered proteins in spinal fluid. As originally used by Lange in 1912, the test was thought to be specific for neurosyphilis; however, this proved to be incorrect. Dilutions of spinal fluid are made in saline and to these a colloidal gold solution is added; if altered proteins are present, there is a colour change or precipitate formed. at present, its chief use is to demonstrate cerebrospinal fluid protein abnormalities in multiple sclerosis. Synonym: gold sol test, Zsigmondy's test. (05 Mar 2000) |

| Langer's arch | pectorodorsalis muscle |
| Langer's lines | Lines which can be extrapolated by connecting linear openings made when a round pin is driven into the skin of a cadaver, resulting from the principal axis of orientation of the subcutaneous connective tissue (collagen) fibres of the dermis; they vary in direction with the region of the body surface. Synonym: Langer's lines. (05 Mar 2000) |

| langer-giedion syndrome | <syndrome> Autosomal dominant disorder characterised by cone-shaped epiphyses in the hands and multiple cartilaginous exostoses. Mental retardation and abnormalities of chromosome 8 are often present. The exostoses in this syndrome appear identical to those of hereditary multiple exostoses (exostoses, hereditary multiple).
