The activities of the aminotransferases, GOT and GPT, were determined in the serum and cerebrospinal fluid of patients with Parkinson's disease, Huntington's chorea, Wilson's disease, amyotrophic lateral sclerosis (ALS), Friedreich's ataxia, phenylketonuria, and head injuries. 1. In patients with Huntington's chorea the activity of SGOT was lower than in controls (P = 0.02); in Friedreich's ataxia LGPT activity was decreased (P less than 0.001); in patients suffering from ALS SGOT (P = 0.005), SGPT (P less than 0.001) and LGOT (P less than 0.001) activities were increased. 2. Long-term treatment of Parkinson's disease and Wilson's disease with L-dopa resulted in an increase in SGOT, LGOT, and SGPT activity over approximately 2 months, with subsequent normalization of these enzyme activities in spite of continued therapy. Guanidine treatment led to an increase in aminotransferase activities in patients with ALS. Penicillamine caused a decrease in SGOT and SGPT activities in Wilson's disease. These results illustrate the necessity of taking therapeutic measures into account in the interpretation of data on aminotransferase activities.

The phenotypic frequencies of 24 polymorphic blood markers in a sample of patients with Huntington's disease (HD) have been compared with those in a sample of healthy Australian volunteers in an effort to detect any associations between HD and the markers concerned. The Rh factor, c, has a significantly lower frequency in the HD sample while ACP1c and Gm1,2 have a significantly higher frequency. The linkage relations of the HD locus have been analysed with respect to the various marker loci concerned. This analysis involved the development of methods to overcome the general lack of genetic data concerning the affected parent and the possibility that presently unaffected offspring may be asymptomatic carriers of the HD gene. The results suggest that close linkage between the HD locus and Fy, ADA, ACP1, Gc or Bg is highly unlikely. They also suggest a low probability of close linkage to ABO, Rh, Jk, Lu, AK1, PGM1 or C3. Positive linkage scores were obtained for P, Hp and Gm. The results are inconclusive for MNSs, K, Le, Se, GPT and Inv. The available data were uninformative for linkage between the HD locus and Co, 6-PGD or E1.

The activities of both mitochondrial and cytosolic forms of alanine aminotransferase are markedly increased in Huntington's disease putamen autopsy samples. This increase was not observed in rats with kainic acid lesions of the striatum, and suggests a considerable alteration of glutamate and pyruvate metabolism as a feature of Huntington's disease.

The Unocal-Metrolink oil spill of 21 February 1995 resulted in approximately 7800 barrels of San Joaquin crude oil being deposited into the San Gabriel River in Huntington Beach, CA, USA. In order to determine long-term pathological effects of oil exposure and rehabilitation, hematological and serum biochemical parameters for both rehabilitated (RHB) American coots (Fulica americana) and reference (REF) coots were examined every 3-4 weeks (56, 81, 108 and 140 days post oil exposure) after birds were cleaned, rehabilitated and soft-released. Most significant differences in monthly comparisons between RHB and REF birds occurred 56 days following oil exposure. Total white blood cell (WBC) count, albumin:globulin (A:G) ratio and calcium concentration were higher in RHB birds compared to REF birds 56 days post oil exposure. In addition, mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC), alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase and creatine kinase activities, and creatinine, total protein (TP) and globulin concentrations were lower in RHB birds. Blood results from 56 days post oil exposure for RHB coots which subsequently died were compared to blood results from days 108 and 140 for REF coots which survived. Oiled and rehabilitated birds which died had significantly higher WBCs, packed cell volume, TP and globulin concentrations, and lower A:G ratio, MCH, MCHC, glucose and sodium concentrations compared to REF birds which survived. Blood result differences detected at 3-4-week intervals between RHB and REF survivors, and differences detected between RHB coots which died and REF coots which survived, suggested that RHB coots developed an inflammatory response (infectious or non-septic) and, concurrently, may have experienced decreased immune responsiveness. Additionally, RHB coots experienced either an iron (Fe) utilization or Fe metabolism problem. These pathophysiological mechanisms were consistent with increased hemosiderin (stored Fe) present in the liver, spleen and kidney of necropsied RHB birds, and may have contributed to RHB coot mortality. When blood parameter differences were examined for their impact on survival time, it was determined that RHB coots had shorter survival times if they had very high cholesterol (> or =449 mg/dl) or chloride (> or =110 MEQ/l) concentrations on day 56 post oil exposure. Interestingly, the lack of differences between RHB and REF coots from day 81 through day 140 suggested that, from a hematologic and clinical chemistry perspective, coots which were oiled, rehabilitated, released and survived at least 3.5 months could not be differentiated from wild (REF) coots. From these findings it appears that blood analysis, coupled with post-release survival data, may help discern reasons for increased mortality of oiled and rehabilitated birds, compared to non-oiled reference birds.
