1. Rats were given moderate-selenium (4-5 mg/kg) or low-Se (0-5 mg/kg) diets during gestation and lactation. Their young were given diets with high (10 mg/kg), moderate or low Se contents from weaning, and groups of rats were killed at intervals during the 14-week experimental peroid. 2. Compared with young rats which received the low-Se diet, those which received the moderate- or high-Se diets had a high incidence of liver lesions and there were changes in liver Se content, haemoglobin concentration, packed cell volume, prothrombin activity, fibrinogen content, spleen weight, body water and serum glutamic-oxaloacetic and glutamic-pyruvic transaminas (L-aspartate : 2-oxoglutarate aminotransferase; EC 2.6.1.1 and L-alanine : 2-oxoglutarate aminotransferase; EC 2.6.1.2 respectively) and alkaline phosphatase (EC 3.1.3.1) activities. In those rats which received the high-Se diet the changes were more pronounced than in those which received the moderate-Se diet. 3. In young rats from dams given moderate-Se diets, which were themselves given the moderate-Se diet, the liver Se content decreased continuously, whereas rats given the same diet but from dams which had received the low-Se diet, the liver Se content increased continuously. There was a slight improvement of symptoms of Se toxicity in all groups by the 5th week of the experimental peroid. 4. The results suggest that there was an adaptation to chronic Se intake.

7 cases of pruritus in pregnancy are reported and their laboratory findings compared with a group of normal pregnant women; then pruritus is reviewed with respect to diagnosis, pathogenesis, therapy, and prognosis. The 7 women developed pruritus in 28-38 weeks of typically the 2nd pregnancy, although during oral contraception in 1 woman. The frequency was about 2/1000 pregnancies. Lab findings suggestive of cholestasis included normal prothrombin, elevated transaminaes, alkaline phosphatase, total bilirubin, total cholesterol, and slowed BSP clearance. None of these women had any history of hepatitis, medication, or positive Australia antigen. It is important in diagnosis to rule out infections, toxic or iatrogenic hepatitis, and especially herpes gestationis, which is teratogenic. Pruritus of pregnancy is identical to that seen during oral contraception, i.e., it is a less severe form of cholestatsis than jaundice. It can be treated with cholestyramine, or will regress spontaneously after delivery, but may cause prematurity.

By means of DEAE-Sephadex A-50 column chromatography, Trimeresurus gramineus venom was separated into 12 fractions. Fraction 8 had marked anticoagulant action in the tests of whole blood clotting time, calcium clotting time and plasma prothrombin time. Fraction 8 was rechromatographed on Sephadex G-100, then on DEAE-Sephadex A-50 again, and finally on Sephadex G-100, and a single peak was obtained. The patterns of microzone and disc electrophoresis also showed a single band. A single symmetrical boundary with 1.70 Svedberg units was obtained by ultracentrifugation. The estimated molecular weight was 19 500. The isoelectric point was pH 4.5. Chemical analysis showed that the anticoagulant principle was a glycoprotein and that it was thermolabile. The anticoagulant activity of this purified principle was 3.5 times higher than that of the crude venom. Fraction 5 potentiated its anticoagulant activity to 10 times higher than that of the crude venom. This principle did not possess caseinolytic, tosyl-L-arginine methyl ester esterase, phospholipase A, phosphodiesterase, alkaline phosphomonoesterase, fibrinolytic, hemorrhagic or local irritating activities. The purified anticoagulant principle did not destroy fibrinogen, induce fibrinolysis, inactivate thrombin nor interfere with the interaction between thrombin and fibrinogen. However, a marked inhibition of prothrombin activation was caused by the anticoagulant principle. The inhibition of prothrombin activation was not due to the destruction of prothrombin or its activation factors, but due to an interference in the interaction between prothrombin and its activation factors because of the reversible binding of these factors with the anticoagulant principle of the venom.

Recent reports of and our own experience with biochemical alterations of liver function secondary to salicylate therapy stimulated this prospective study. Thirty-four children with juvenile rheumatoid arthritis, 6 children with acute cartilagenous necrosis of the hipfollowing slipped capital femoral epiphysis, and 2 children with ulcerative colitis and hip disease who were on salicylates were followed over a period of 1-27 months with serial determinations of serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), lactic dehydrogenase (LDH), alkaline phosphatase (AP), bilirubin, and serum salicylate. Prothrombin time was measured in 14 children. Twenty-two of 34 children with rheumatoid arthritis and none of the 8 controls demonstrated abnormalities of various liver functions at serum salicylate levels between 7.0 and mg%. Three children demonstrated severe abnormalities characterized by marked elevation of SGOT, SGPT, LDH, and AP, prolongation of prothrombin time, and epistaxis. This type of reaction occurred within 5-14 days of initiation of aspirin therapy and occurred at serum salicylate levels between 18 and 43 mg%. Moderate changes in various liver function tests were observed in 19 other children. None of those children who were tested showed prolongation of prothrombin time. The serum salicylate level in this group varied between 7.0 and 38.2 mg%. The abnormal liver function tests returned to normal in 6 children upon withdrawal of aspirin and in 12 others even when salicylates were continued. Therefore, despite the occurrence of biochemical abnormalities following chronic salicylate therapy, it does not appear to be necessary to discontinue their use except in those children who develop bleeding.

Clinical and laboratory findings from 15 patients with icteric viral hepatitis during pregnancy (VHP) and from 22 patients with intrahepatic cholestasis during pregnancy (CJP) were evaluated statistically in order to find out which parameters might help in order to find out which parameters might help in differentiating the two diseases. Diagnosis was established by needle liver biopsy in all cases. The following data were considered: history, physical examination, erythrocyte sedimentation rate (ESR) serum cholesterol, prothrombin time, total serum bilirubin, SGOT, SGPT, serum alkaline phosphatase, serum protein, serum flocculation tests, BSP blood clearance and serum HB Ag. Vomiting, high GOT and GPT serum levels, and serum HB Ag positivity suggest VHP diagnosis. Otherwise a severe itching with scratching lesions, high ESR, elevated total cholesterol and serum alkaline phosphatase values mainly if occurring in the later stage of pregnancy are consistent with CJP diagnosis. When clinical and laboratory data from a jaundiced pregnant female do not allow diagnosis, this can be established only on the basis of needle liver biopsy.

In two patients with renal cell carcinoma, the following biochemical changes were found independently of hepatic metastases: increased alkaline phosphatase activity, rise in bromsulfothalein retention, hypoalbuminemia, increase in alpha2-globulin, and prolonged prothrombin time (Stauffer syndrome). In both cases the syndrome was found to be the first sign of the renal cell carcinoma. In one patient liver function returned to normal after removal of the neoplasm, in correlation with the good recovery. In the other case the abnormal laboratory findings persisted after total renal surgery. Clinically, diffuse pulmonary metastases occurred. Both case histories show the high significance in knowing Stauffer syndrome and its value for early diagnosis and operative success.

The diagnosis of pancreatic disease is difficult. The first step is clinical suspicion, based on the symptoms and signs. If pancreatic disease is suspected, investigation is necessary to prove this diagnosis. Investigation aims to answer two questions: a) is there pancreatic disease and b) if so, what type? The first question may be answered by demonstrating abnormal pancreatic function, using pancreatic function tests, whereas the second is answered by using techniques to demonstrate structural (anatomical) abnormalities of the pancreas. a) The methods to establish abnormal pancreatic function consist of 1. tests to demonstrate abnormal digestive capability, 2. tests to study pancreatic exocrine secretion, and 3. tests to study endocrine secretion. The tests of group 1 are: chemical fat balance study before and during enzyme replacement therapy, faecal nitrogen balance study, and the demonstration of either the malabsorption of vitamins A, D and K or the sequelae of their malabsorption (low serum calcium, high alkaline phosphatase, prolonged prothrombin time, etc.). Abnormal vitamin B12 absorption also may be present. 2. The tests designed to study pancreatic exocrine secretion are determination of the presence or absence of proteolytic enzymes in the stool, the secretion test, the pancreozymin stimulation test and the Lundh test. The serum amylase and lipase values are of little help in assessment of pancreatic function. 3. The tests to study endocrine function are the glucose tolerances test (which frequently gives abnormal results in pancreatic disease), and radioimmunoassays for insulin and gastrointestinal hormones (which may be increased in patients with functioning tumours of the islet cells). b) The techniques used to establish structural abnormalities of the pancreas are: duodenal cytology (during secretin tests), radiological techniques (abdominal survey films, barium meal, hypotonic duodenography, roentgenography of the biliary tract, barium enema, and angiography,) gastroscopy, duodensocopy, endoscopy and retrograde pancreatography, echography, scan and laparotomy. The relative value of these tests is discussed.

We sought to determine if there were any differences in the results of clinical laboratory tests between blood samples collected from the orbital venous plexus and the posterior vena cava of adult male rats. Thirty healthy adult male Sprague Dawley rats were anesthetized by ether inhalation, and blood samples were collected successively from the orbital venous plexus (OVP) and the posterior vena cava (PVC) for hematologic (n = 10), serum chemistry (n = 10), and coagulation (n = 10) analyses. The prothrombin and partial thromboplastin times of samples from the OVP were prolonged (17% and 288%, respectively) when compared with samples from the PVC. Respective hematologic biases were as follows: red blood cell count (7%), hemoglobin (6%), hematocrit (5%), mean corpuscular volume (-3%), mean corpuscular hemoglobin (-1%), mean corpuscular hemoglobin content (1%), white blood cell count (13%), and platelet count (-7%). Respective serum chemistry biases were as follows: sorbitol dehydrogenase (-7%), glucose (-7%), blood urea nitrogen (-10%), creatinine (-2%), total protein (4%), albumin (2%), globulin (9%), alkaline phosphatase (5%), lactate dehydrogenase (-6%), aspartate aminotransferase (-5%), alanine aminotransferase (-2%), total bilirubin (0%), direct bilirubin (0%), magnesium (-17%), sodium (4%), potassium (0), chloride (4%), calcium (-2%), phosphorous (-17%), cholesterol (3%), triglycerides (24%), creatinine kinase (-8%), 5'nucleotidase (0%), and total bile acids (4%). For hematologic testing, there were no biologically significant differences between samples collected from the OVP and PVC. The coagulation times and serum Mg and P showed biologically significant differences between samples collected from the OVP and PVC.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to describe biochemical and liver function test changes after hepatectomy in 33 patients with the following characteristics: absence of underlying liver disease, no blood or plasma transfusion during the perioperative period, uneventful postoperative course. Resection with a temporary pedicle inflow occlusion (10-45 min) consisted of unisegmentectomy or less in 15 patients and bisegmentectomy or more in 18. Blood tests showed: a correlation between aminotransferase rise and duration of ischaemia, and a fall in prothrombin time and factor V levels correlating with the weight of resected specimen at day 1; a moderate gamma-glutamyl transpeptidase and alkaline phosphatase elevation and a rise in fibrinogen level correlating with the extent of resection at day 7. Changes in haemoglobin level, white cell count, platelet count, prothrombin time, factor V level and serum bilirubin level tended to return to preoperative levels by day 7. For gamma-glutamyl transpeptidase and alkaline phosphatase, increased levels persisted for 8-12 weeks after resection. These results, in this selected group of patients, allow a description of the 'natural history' of hepatectomy. The knowledge of these 'natural' changes may contribute to the early detection of postoperative complications.

Primary biliary cirrhosis (PBC) is a relatively rare autoimmune disorder leading to the destruction of the interlobular biliary epithelium, which has not been reported in the Middle East. We studied 30 patients with PBC who had been referred to the Liver Unit at the Hadassah Medical Center in Jerusalem. The diagnosis was established by conventional criteria in 28 female and 2 male patients. Twenty-two patients were of Ashkenazic origin and 8 of Sephardic background. Mean serum alkaline phosphatase activity at the time of diagnosis was 911 IU/l gamma-glutamyl transpeptidase 677 u/l, cholesterol 73 mmol/l, albumin 3.2 g/l, bilirubin 72 mmol/l, and prothrombin time was 65%. All patients had positive antimitochondrial and M2 antibodies, and the mean IgM level was 684 mg/dl. The diagnosis was confirmed by liver biopsy in 27 of 30 patients. To the best of our knowledge this represents the first report of primary biliary cirrhosis in the Jewish population in Israel. This retrospective survey raises the question whether the disease is indeed rare in Israel or, alternatively is underdiagnosed.
