GABA(A) receptors are the major inhibitory neurotransmitter receptors in the brain and are the site of action of many clinically important drugs. These receptors are composed of five subunits that can belong to eight different subunit classes. If all GABA(A) receptor subunits could randomly combine with each other, an extremely large number of GABA(A)(More)
SINJ is a new continuous human cell line derived from a lymph node metastasis of a probably sporadic medullary thyroid carcinoma. It is compared to MTC-SK, another medullary thyroid carcinoma cell line, established earlier (1). SINJ has been continuously cultivated in vitro for two years. The cells grow as a suspension of single cells and cell clusters.(More)
Genetically diabetic mice (db/db) were given 50 mg/kg body weight/day substance L, a nontoxic basic amino acid and compared to control diabetic mice without treatment. The oral administration of the compound was started at the age of 3 months and the animals were sacrificed at the age of 7 months. No adverse effects were observed in animals given the(More)
Polyclonal antibodies were raised to synthetic peptides having amino acid sequences corresponding with the N- or C-terminal part of the gamma-aminobutyric acidA (GABAA) receptor alpha 5-subunit. These anti-peptide alpha 5(2-10) or anti-peptide alpha 5(427-433) antibodies reacted specifically with GABAA receptors purified from the brains of 5-10-day-old rats(More)
Polyclonal antibodies were raised to synthetic amino acid sequences of the bovine GABAA receptor alpha 2- and alpha 3-subunits and purified by affinity chromatography on a column coupled with the respective peptide. Anti-peptide alpha 2(416-424) and anti-peptide alpha 3(459-467) antibodies immunoprecipitated GABAA receptors and recognized a protein of 53(More)
In the present study, we tested the hypothesis whether creatine, a metabolite of arginine metabolism, shares the pharmacological activities of arginine reducing collagen accumulation in the diabetic kidney. Ten db/db mice were given, for 3 months, a solution containing a daily dosage of creatine of 50 mg/kg body weight. Eleven db/db mice served as controls.(More)
A new continuous cell line from a human malignant carcinoid of the small intestine (KRJ-I) was established. The cells showed morphological and immunocytochemical features of the tumor of origin and expressed estrogen receptors. The cells are growing as a suspension, forming multicellular aggregates and spheroids. Electron microscopy confirmed the presence(More)
A total of 120 male rats of the Sprague-Dawley-strain (6 weeks old) were used in this experiment. 5 groups of 12 animals each were treated intraperitoneally with 200 ng gonadotropin releasing hormone (LH-RH) per animal. 30 minutes later blood was sampled by heart puncture. Group I were animals without transport, group II immediately after, group III one(More)
In this study the influence of a severe catabolic situation (scalding and nitrogen deprivation) on amino acid (AA) metabolism was investigated in an experimental rat model. Scalding of 25 per cent of the total body surface area (TBSA) and hypocaloric alimentation (5.6 kcal per 100 g rat per day, no nitrogen) resulted in mean daily nitrogen losses of -0.27(More)
A new mutation, affecting skin and hair, occurred in an expansion colony of Him:OF1 mice. Test crosses showed that a single autosomal recessive gene was responsible for this trait. Homozygotes have sparse greasy fur and lower viability and fertility than normal littermates. Histological observations showed hypertrophy of sebaceous glands, hyperkeratosis,(More)
