Water hardness is a measure of the dissolved mineral content of water. There are two types: the general hardness (GH) and carbonate hardness (KH). When keeping freshwater fish and plants, the GH and the KH of aquarium water should match their natural habitat.
Hypersecretion of growth hormone causes gigantism in children and acromegaly in adults. Evaluation of growth hormone hypersecretion cannot be excluded with a single normal GH level due to diurnal variation.However, a random blood sample showing markedly elevated GH is adequate for diagnosis of GH hypersecretion.n humans, this condition is caused by over-production of growth hormone in childhood resulting in persons between 2.13 m (7 feet or 84 inches) and 2.74 m (9 feet or 108 inches) in height.
