Chloroform (CF) is a widely used industrial chemical that can also pollute the environment. It is a recognised cause of acute liver injury, although now rarely encountered in clinical practice. Chloro Form is a common contaminant in the drinking water.
Chloroform has been used over decades in anesthesia before it was replaced by other volatile anesthetics like halothane or sevoflurane. Its chloroform extract has the greatest killer activity against E. coli. It has a high solubility for lipids and accumulation of lipids in the liver might become a risk factor for liver injury.
Chloroform does not cause a chemical labyrinthectomy as previously assumed, although it is severely ototoxic. It can also activate enzymes.

Turbine was most toxic followed by halothane and chloroform, which caused similar levels of cell injury. Fumonisins B1 and B2 were extracted from the CM by water, but not chloroforms. The results obtained are sufficiently reproducible to yield an order of cytotoxicity.
The goals of this paper are to develop a biological and pharmacokinetic modeling approach for chloroform. The aim is to evaluate Haber's rule for different ages by taking into account the physiological changes due to growth and aging in rats.

| Absence Status [description not available] | 0 | 2.17 | 1 | 0 |
| Status Epilepticus A prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. The most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. Nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. Simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also EPILEPSIA PARTIALIS CONTINUA). Subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity.

| Vitamin A Deficiency A nutritional condition produced by a deficiency of VITAMIN A in the diet, characterized by NIGHT BLINDNESS and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (XEROPHTHALMIA).

| Anemia, Hypochromic Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions.

| Folic Acid Deficiency A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur. (Merck Manual, 16th ed) | 0 | 1.94 | 1 | 0 |
| Vitamin B 12 Deficiency A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis.
