Protein C is a vitamin-K-dependent plasma glycoprotein that when activated inhibits coagulation by selectively inactivating the active forms of factor V and factor VIII. A specific antiserum to protein C has been raised, and plasma protein C levels have been measured by means of an electroimmunoassay in several physiological and pathological conditions. In 60 healthy adults there were no differences in protein C related to age or sex; protein C levels ranged from 72 to 139% of values in a normal plasma pool. Low levels were found in 12 healthy full-term newborn infants; the levels in 20 women in the last trimester of normal pregnancy were no different from those in healthy non-pregnant women. In 58 patients with chronic liver diseases protein C levels were lower than those in healthy subjects, in degrees roughly proportional to the severity of the disease. Protein C levels were very low in 21 patients with the disseminated intravascular coagulation syndrome, particularly in those who had evidence of consumption coagulopathy. Very low levels were also found, however, in 20 patients with adult respiratory distress syndrome without consumption coagulopathy. Acquired defects of protein C developed after surgery in the patients operated on for malignancies, after major abdominal operations for benign conditions, and also after relatively minor procedures such as appendicectomy and hernia repair. These findings indicate that protein C deficiencies occur in several conditions associated with increased tendency to thrombosis.

Protein C is the important regulating factor of coagulation and fibrinolytic system. It is known that surgery causes disturbances of haemostasis. The aim of work was to study the influence of different kind of surgery on the protein C activity. The study contained 102 operated patients in whom vascular operation (20), operation of prostate because of carcinoma (20) and hypertrophy (40), cholecystectomy (12) and operation of hernia (10) were performed. Protein C activity was measured using Kabi Diagnostika test applying chromogenic substrate. In the most of patients surgery caused on the 0 and 1st postoperative day the decrease of protein C activity and the return to the preoperative values in the next few days. The exception was the hernia operation which did not diminish protein C activity. It seems that the decrease of protein C after surgery was the effect of consumption of it in the extremely activated coagulation and fibrinolytic system during operation.

A small supernumerary marker chromosome (SMC) was observed in a girl with severe developmental delay. Her dysmorphism included prominent forehead, hypertelorism, down-slanting palpebral fissures, low-set/large ears, and flat nasal bridge with anteverted nares. This case also presented hypotonia, hypermobility of joints, congenital heart defect, umbilical hernia, failure to thrive, and seizures. The SMC originated from the distal region of Xp as identified by FISH with multiple DNA probes. Staining with antibodies to Centromere Protein C (CENP-C) demonstrated a neocentromere, while FISH with an alpha-satellite DNA probe showed no hybridization to the SMC. A karyotype was described as 47,XX,+neo(X)(pter-->p22.31::p22.31-->pter), indicating a partial tetrasomy of Xp22.31-->pter. This karyotype represents a functional trisomy for Xp22.31-->pter and a functional tetrasomy for the pseudoautosomal region given that there is no X-inactivation center in the marker chromosome. The SMC was further characterized by microarray-based comparative genomic hybridization (array CGH) as a duplicated DNA fragment of approximately 13 megabase pairs containing about 100 genes. We have described here a new neocentromere with discussion of its clinical significance.
