RESUMO
The distribution of C3 phenotypes in the population of Veneto was investigated by electrophoresis on agarose gel. In our sample (n = 810) the three common phenotypes C3 SS, C3 FF and C3 FS and a further phenotype, C3 S-VF, were observed. The following gene frequencies could be calculated: C3S = 0.8068, C3F = 0.1926 and C3V = 0.0006. These frequencies have been compared with those found in other populations. The analysis of 21 mother-child pairs was in agreement with an autosomal codominant inheritance.

The distribution of Bf phenotypes in the population of Veneto was investigated by agarose gel electrophoresis and immunofixation. In our sample (n = 592), the seven common phenotypes F, S, F-S, S-S0.7, S-F1, F-S0.7, F-F1 were observed and the following gene frequencies calculated: Bf*S = 0.7399; Bf*F = 0.2280; Bf*F1 = 0.0177; Bf*S0.7 = 0.0144. These gene frequencies are compared to those found in other populations. Analysis of 21 mother-child pairs was in agreement with an autosomal codominant inheritance.

The Asmat are a population of about 35,000 people living on the South-West coast of Irian-Jaya (Indonesia; New Guinea). This paper presents the results of enzyme group and serum protein group typings in a sample of Asmats living in the coastal region around Agats. Red cell enzyme polymorphisms (EaP, PGM1, 6-PGD, EsD, ADA and AK) could be typed in 154 blood samples, serum protein polymorphisms (Ge, alpha 1-AT, PLG, Tf and Hp) in 160 blood samples. The results of this study are discussed in detail.

The distribution of plasminogen phenotypes in the population of Veneto was investigated by ultrathin-layer isoelectric focusing. In our sample (n = 1325), the three common phenotypes PLG1, PLG2, PLG2-1 and two further phenotypes PLG1-V and PLG2-V were, observed and the following frequencies calculated: PLG1 = 0.84038; PLG2 = 0.15811; PLGV = 0.00151. These gene frequencies are compared to those found in other populations. Analysis of 41 mother-child pairs was in agreement with an autosomal codominant inheritance.

The occurrence of PGM1 phenotypes in 589 samples from the population of Padua was investigated by ultrathin-layer isoelectric focusing. All ten phenotypes were observed. Frequencies of the PGM1 alleles (1+ = 0.6180; 1- = 0.1163; 2+ = 0.2122; 2- = 0.0535) have been compared to those found in other populations.

The absorption-elution technique with low ionic strength solution (LISS) and papain-treated test cells previously used for bloodstains was employed for the detection of ABO antigens on human hair. Antigen identification was always possible, with good intensity of agglutination, even in those cases where classic techniques had given false-negative results. It was possible to obtain positive results with fragments of human hair as small as 0.2 cm.

The distribution of Gc phenotypes in the population of Veneto was investigated by ultrathin-layer isoelectric focusing. In our sample (n = 732) the six common phenotypes, Gc 1S, 1F, 1S1F, 2, 2-1S, 2-1F and a further phenotype, GC 1S1C3, were observed and the following frequencies calculated: Gc 1S = 0.560792; GC 1F = 0.159153; Gc2 = 0.277323; Gc 1C3 = 0.002732. Our gene frequencies have been compared with those found in other populations.

The distribution of Tf phenotypes in the population of Padua was investigated by ultrathin-layer isoelectric focusing. In our sample (n = 618) nine phenotypes, Tf C1, C2, C3, C3-1, C2-1, C3-2, C1B, C2B and C1D, were observed and the following frequencies calculated: TfC1 = 0.77837; TfC2 = 0.1804; TfC3 = 0.03641; TfB = 0.0040; TfD = 0.0008. These gene frequencies have been compared to those found in other populations. Analysis of 101 mother-child pairs was in agreement with an autosomal codominant mode of inheritance.

A case of traumatic rupture of the anterior papillary muscle is presented. The patient survived for 3.5 h after injury without showing any serious cardiac symptoms, and in the absence of external chest injuries. Cardiac injury should always be suspected after a head-on collision, even if significant symptoms are missing.
