Is a loving encounter in a psychiatric facility even possible? Findings about the current situation in medicine and care are often gloomy, alarming in many ways. Well-known, justified demands are on the agenda and, not least in view of other social challenges, find little resonance. The fact that it is still possible in practice, mostly unnoticed by the general public, to attentively and lovingly support people with existential challenges is worked out with a contribution from a day hospice, which is representative of other psychiatric institutions.

Immunogenetic markers in patients with Graves' disease.

110 carefully characterized Caucasoid patients with Graves' disease were tested for HLA class I and class II antigens. Compared with Caucasian controls (n = 193), the frequencies of HLA B8, Cw7 and DR3 were significantly increased (pc less than 0.05).

[Blood group expert evaluation: relation between the extent of testing and the reliability of paternity determination. Reflections on revision and guidelines].

In affiliation cases a combined exclusion chance for non-fathers of 99.995% is obtained by the examination of well-established blood group systems. In complicated cases, i.

[Blood group expertises including related presumptive fathers (author's transl)].

In four affiliation cases with two or three brothers involved as putative fathers, exclusions of non-fathers were obtained by the application of the so-called isoelectrofocusing systems (twice by PiM subtypes, once by PGM1, TfC and Gc1 subtypes) as well as by GPT and the extended Gm system. In three cases a discrimination between the involved brothers was possible, in a fourth case both brothers were excluded from paternity. Special problems of anthropological expertises and of biostatistics in cases with closely related putative fathers are discussed.

A new procedure for the determination of transferrin C (Tf C) subtypes by isoelectric focusing. Existence of two additional alleles, Tf C4 and Tf C5.

Isoelectric focusing (IEF) is widely used for the determination of serum protein polymorphisms in forensic investigations. Because of non-genetic heterogeneity of some proteins and of protein-ligand dissociation observed after IEF standardization of procedures is necessary. In this article the authors point out the main difficulties encountered in studying the transferrin subtype polymorphism and describe a new and sensitive method.

The efficacy of modern blood group genetics with regard to a case of probable superfecundation.

The reported case of probable superfecundation is apparently the most extensively tested of all published cases: More than 40 specificities of the HLA Loci A and B, 5 of the Locus C, Bf and GLO I, furthermore ABO, MNSs, DCcCwEe, K 1--6, Fya, Fyb, Jka, Jk5, Lu3, Hp, Gc, Gm 1, 2, 4, 5, 21, Km 1, C3, Tf including C-subtypes, Pi, Bg, ACP, PGM1 including the extended polymorphism by PAGIF, AK1, ADA, 6-PGD, EsD, GPT, GALT, CAII and Hb. A reciprocal exclusion for putative father 1 and putative father 2 to the twin 2 and the twin 1, respectively, has been reached in 7 blood group systems: HLA, MNSs, Lu, Hp, Tf, Bg and GPT. The random probability for the fatherhood of an unknown third man suitable for both twins is extremely low among whites (1 : 10(8)) or blacks (1 : 10(9)).

PEP A9, a new, unstable variant in the peptidase A system.

A rare peptidase A variant, tentatively designated PEP A9, was observed in six members of a German family, indicating autosomal codominant inheritance. The electrophoretic mobility is similar to that of PEP A 3-1, but it has very low in vivo stability. There is no apparent association with a disease state.

Isoelectric focusing of rare transferrin (Tf) variants and common TfC subtypes.

TransferrinC (TfC) subtypes were determined by isoelectric focusing (PAGIF) on samples from 90 carriers of the TFB and TfD alleles. In all cases of CB and CD heterozygotes only one of the two common subtypes of the TfC allele, TfC1 or TfC2, was observed. This is considered strong support for the hypothesis of two common alleles at the Tf locus.

A third common allele in the transferrin system, TfC3, detected by isoelectric focusing.

Further genetic heterogeneity of the transferrin system (Tf) was revealed by prolonged isoelectric focusing (PAGIF) of human sera on polyacrylamide gels (pH 4--6.5). One of the two common subtypes of TfC, designated previously as TfC1, is split into TfC1 and the new subtype, TfC3.

PiT: a new allele in the alpha 1-antitrypsin system.

In a genetic investigation of the population in Hessen, Germany, we found a family with a new, rare allele in the Pi system (alpha 1-antitrypsin). According to electrophoretic analysis and isoelectric focusing patterns, it is designated PiT. A pedigree study suggests autosomal codominant inheritance.

Report of a working group for the European Pharmacopoeia. Collaborative assay on human albumin of different origin.

A collaborative assay was conducted by 9 laboratories on 31 samples of human albumin which were in clinical use. It was the object of the study to establish test systems which would differentiate between albumins of venous or placental origin. The properties examined for this purpose were: appearance, total protein, haem, polymers, alkaline phosphatase and blood group substances.

Transferrin: evidence for two common subtypes of the TfC allele.

Evidence is presented for an extended polymorphism of human transferrin (Tf). Three common phenotypes were observed among TfC individuals after isoelectric focusing of sera on polyacrylamide gels. They are explained in terms of two subtypes of the TfC allele, tentatively designated TfC1 and TfC2.

Investigations on the PGMa1 polymorphism (phosphoglucomutase--EC 2.7.5.1) by isoelectric focusing.

The determination of phosphoglucomutase (PGM1) phenotypes was performed by isoelectric focusing on samples from 1678 unrelated individuals from Hessen, Germany. Ten common phenotypes are considered as gene products of four alleles at the PGM1 locus with the following frequencies: PGMa1(1) = 0.6305, PGMa2(1) = 0.

Properdin factor b-polymorphism in the population of Hessen, Germany.

The polymorphism of properdin factor B (Bf, C3 proactivator) in a population sample from Hessen, Germany has been investigated by agarose gel electrophoresis and immunofixation. In 522 unrelated individuals seven different phenotypes were observed and the following allele frequencies calculated: BfS = 0.7998, BfF = 0.

An improved method for the identification of Gc1 subtypes (group-specific component) by isoelectric focusing.

The occurrence of common subtypes of the Gc1 gene in a German population (n = 261) was investigated by isoelectric focusing on thin layers of polyacrylamide in the pH range 4-6. Six common phenotypes designated Gc 1S, 1F, 1F-1S, 2-1S, 2-1F, and 2 are considered as gene products of three common alleles with the following frequencies: Gc1S=O.603, Gc1F=0.

Investigations on the polymorphism of sperm diaphorase in man. Evidence for a third common allele, SD.

The polymorphism of sperm diaphorase (SD) was investigated in 141 unrelated persons from Hessen, Germany, by high voltage thin-layer agarose gel electrophoresis (Age) and thin-layer isoelectric focusing on polyacrylamide gel (Pagif). In addition to the three known common phenotypes SD 1, 2-1, and 2, two further phenotypes with the preliminary designation SD 3-1 and SD 3-2 were discovered. This polymorphism can thus be explained in terms of three alleles, SD1, SD2, and SD3 segregating at an autosomal locus.

Investigations on the polymorphism of glyoxalase I (EC 4.4.1.5) in the population of Hessen, Germany.

The phenotypes of glyoxalase I (GLO) were determined in a random population from Hessen (Germany) by high-voltage agarose gel electrophoresis. The gene frequencies in 1150 unrelated individuals were 0.4391 for GLO1 and 0.

Occurrence of Su in a German family.

Investigating a paternity case we observed a pretended opposite homozygosity of the S and s alleles between a mother and her child. The presence of the rare allele Su in this family could be demonstrated with the aid of dosage studies and blood group testing of the mother's parents. 22 additional genetic marker systems, including the HLA-system were examined, a biostatistical calculation was performed as well.

Evidence for two additional common alleles at the PGM1 locus (phosphoglucomutase--E.C.: 2.7.5.1). A comparison by three different techniques.

Lysates of erythrocytes, leukocytes, lymphocytes, and extracts of sperms were investigated for the PGM1 isozymes by three techniques: starch gel electrophoresis, high voltage thin-layer agarose gel electrophresis, and thin-layer isoelectric focusing on polyacrylamide gel. On starch, only the well known common phenotypes 1, 2-1, and 2 were demonstrable. On agarose, different distances of the two main cathodal bands (a,b) among the phenotypes 2-1 were noted.
