We retrospectively reviewed 159 episodes of bacteraemic pneumococcal infection in 157 adult patients at the Helsinki University Central Hospital during two periods between 1976 and 1979 and 1986 and 1989. We looked especially at changes in underlying diseases and prognostic factors. The overall case fatality rate was 21% and there was a small diminishing trend in that rate from 28% (16/58) in the late 1970s to 17% (17/101) in the late 1980s. The patients who died in the late 1980s were younger than those who died in the earlier period. The most common underlying factors were alcohol abuse, cardiovascular diseases and chronic obstructive pulmonary diseases. Old age was neither a predisposing factor nor did it predict the outcome. No significant changes in underlying diseases or prognostic factors were noted during the two periods studied except a small decrease in connective tissue diseases as underlying conditions. The factors related to increased fatality included hepatic cirrhosis, a combination of pneumonia and meningitis, complications such as shock, respiratory insufficiency, central nervous system disorders and circulatory acidosis, and laboratory findings such as thrombocytopenia, absence of leucocytosis and increased amounts of serum creatinine, aspartate aminotransferase and alanine aminotransferase on admission to the hospital. Previous splenectomy and malignant diseases were not associated with higher mortality. The thrombocytopenia at the time of positive blood culture and the circulatory acidosis as a complication seemed to be independently the most useful predictive factors for a fatal outcome using multivariate logistical regression analysis after adjustment to classic risk factors.

Curcumin, the active principle of turmeric, is known to act as an anti-oxidant, anti-mutagen and anti-carcinogen in experimental animals. In the present study, anti-mutagenic effects of turmeric were assessed in 16 chronic smokers. It was observed that turmeric, given in doses of 1.5 g/day for 30 days, significantly reduced the urinary excretion of mutagens in smokers. In contrast, in six non-smokers, who served as control, there was no change in the urinary excretion of mutagens after 30 days. Turmeric had no significant effect on serum aspartate aminotransferase and alanine aminotransferase, blood glucose, creatinine and lipid profile. These results indicate that dietary turmeric is an effective anti-mutagen and it may be useful in chemoprevention.

We investigated the early changes of tubules and effect of the oral adsorbent, AST-120, on the early changes of tubules in rats with chronic renal failure. Sprague-Dawley rats were divided into two groups with and without AST-120, after 3/4 nephrectomy. Although there were no significant differences in levels of blood urea nitrogen, serum creatinine, creatinine clearance, inulin clearance, para-aminohippuric acid clearance and urinary N-acetyl-beta-D-glucosaminidase at week 8 between the two groups, the amount of 24-hour urinary protein excretion and the direct systolic blood pressure at week 8 were significantly decreased in the group with AST-120. Examinations by light microscopy at week 8 revealed that proteinaceous casts in the tubules, tubular dilatation and infiltration of monocytes into the interstitium in the group with AST-120 were less prominent than those in the group without AST-120. A significant difference in numbers of proteinaceous casts was noted at week 8 between the two groups. In rats with chronic renal failure at the early stage, it is concluded that the formation of proteinaceous casts, resulting in tubular damage, is increased and that AST-120 delays the occurrence of proteinaceous casts by delaying the increase in urinary protein excretion.

The number of clinical chemical analyses performed on blood in the County of Frederiksborg in 1990 was 3.7 per inhabitant. The number of analyses requested increased by only 2.5% since 1986. Approximately 1/3 of the analyses were requested from primary care and about 1/5 of these analyses were performed in the doctors' offices. Approximately 100 different kinds of analyses were requested, but the 10 (20) most frequent analyses requested in 1990 account for 62 (80%) of the analyses requested from the hospitals and 73 (89%) of the analyses requested from primary care. Approximately 50% of the analyses requested for B-hemoglobin and B-sedimentation rate and about 70% of the analyses requested for B-glucose was performed in the doctors' office in 1990. Only the number of analyses requested for B-glucose has increased (50%) since 1986. The three analyses account for more than 90% of the clinical chemical analyses performed on blood in the doctors' offices. The pattern of analyses for the ten most frequent analyses requested from primary care differs from the pattern of analyses requested from the hospitals. As compared with the number of analyses requested for P-creatinine, the analyses P-aspartate aminotransferase, P-alkaline phosphatase, B-sedimentation rate and B-differential counts were requested more than twice as frequently from primary care as from the hospitals. The pattern of analyses requested for a number of the 20 most frequently requested analyses shows considerably variation from hospital to hospital. This is especially pronounced for B-sedimentation rate and B-leucocyte counts.

A total of 120 (80 males and 39 females) newborn Holstein-Frisian calves suffering from acute diarrhoea were studied clinically and biochemically, including the following parameters: pH, pCO2, act. HCO3, BE, RBC, PCV, HV, glucose lactate, urea, creatinine, total bilirubin, total protein, AST, Na, K and Cl. The results were interpreted according to their healthy condition, their age as well as their sex. The study had revealed an extreme metabolic acidosis, haemoconcentration, hypoglycaemia and hypofunction in the kidney and liver. Furthermore, the calves with diarrhoea had showed hyponatraemia, hypochloraemia, and hyperkalaemia. Important correlations between clinical and some blood parameters were found. Metabolic acidosis was more severe in male calves than females. These pathophysiological changes should be put in consideration during the therapy of newborn calves suffering from diarrhoea.

Egyptian scorpion venom was collected by electrical stimulation of the telson. Rats were injected with the lyophilized venom in 3 different doses (100, 200 and 400 micrograms/kg). Blood samples were drawn by heart puncture before and 4 h after venom administration. Serum was separated and collected for determination of glucose, blood urea nitrogen (BUN), creatinine, uric acid (UA), total proteins, cholesterol, sodium, potassium, calcium, inorganic phosphorus, alkaline phosphatase, aspartate aminotransferase (AST, GOT), alanine aminotransferase (ALT, GPT), lactate dehydrogenase and creatine phosphokinase (CPK). Serum glucose, creatinine, GOT, GPT and LDH were increased significantly in all treatments. At the same time serum BUN and CPK were elevated significantly with a dose-response relationship. On the other hand, serum total proteins, uric acid, cholesterol, calcium and potassium were significantly decreased 4 h after administration of the 3 doses. These changes in clinical chemistry parameters are most probably related to the toxic effect of the venom on the target organs.

Progression of renal insufficiency was evaluated in partially nephrectomized Sprague-Dawley rats at the age of 10 weeks, fed on the low (6%), usual (20%), and high (36%) protein diet (group 6C, 20C, and 36C). Effects of oral adsorbent AST-120 on these experimental uremic models were also examined (group 6A, 20A, 36A). All the rats underwent paired feeding, and survived during the experimental period of 3 weeks. GFR (inulin clearance) and RPF (para-amino hippurate clearance), as well as Ccr was measured before the sacrifice. Initial serum creatinine and Ccr were 1.7 mg/dl and 0.27 ml/min. The rats of group 36C showed progressive elevation of serum creatinine level and decrease in Ccr. At the end of the study, GFR was significantly lower in group 36C than in group 6C and 20C (0.19, 0.68, 0.87 ml/min respectively). Significant elevation of filtration fraction in group 36C suggested that the decrease in GFR mainly resulted from low RPF. Even in group 36C, no glomerular sclerosis was histologically demonstrated in the remnant kidney, and the mean planar area of the remnant glomeruli was significantly small, which might reflect low RPF. Tubulo-interstitial changes like dilatation of the urinary space and tubular epithelial flattening were prominent in group 36C. Beneficial effect of AST-120 was obvious in high protein diet groups. GFR and RPF were rather well preserved in group 36A (0.36 and 0.78 ml/min) with normal filtration fraction. Tubulo-interstitial damage was evidently mild in group 36A. These data suggested the presence of some humoral factors, which can be adsorbed by AST-120 in gastrointestinal tract, and responsible for the deterioration of renal function and tubulo-interstitial damage induced by high protein diet in the uremic condition. Besides hyperfiltration and glomerular hypertrophy, such humoral factors as suggested in this study may contribute to the progression of chronic renal failure to some extent.

Blood samples were collected from v. jugularis in five-day intervals from parturition to postpartum day 45 in the rearing conditions of a dairy cow production herd, consisting of 10 groups with 10 pluriparous cows each (crossbreds of Bohemian Pied cattle with Holstein-Friesian cattle). In blood serum the following activities were determined photometrically: aspartate aminotransferase--AST (0.36-0.47 mukat.l-1), gamma-glutamyl transferase--GMT (0.50-0.83 mukat.l-1) and lactate dehydrogenase--LD (7.22-9.10 mukat.l-1); their average values were at an almost constant level. Only did AST and GMT values decrease slightly from day 25 after parturition. The glucose average content on the day of parturition (4.07 mmol.l-1) steeply decreased to postpartum day 5 (2.79 mmol.l-1), and later on, it increased irregularly. The average values of total protein (66.7-73.2 g per 1) slightly increased from postpartum day 20. The values of urea (2.33-2.37 mmol.l-1) and bilirubin (3.49-5.15 mmol.l-1) did not show any larger changes in dependence on the time elapsing from parturition. The average content of creatinine (124-162 mmol.l-1) increased irregularly from postpartum day 15 and then it decreased. Cholesterol concentrations were gradually increasing from 2.58 mmol.l-1 on the day of parturition to 4.99 mmol.l-1 on day 45 after parturition. The average contents of calcium (2.20-2.66 mmol.l-1) and phosphorus (1.75-2.27 mmol.l-1) were irregularly increasing until day 20 after parturition. Also the average content of magnesium (0.86-1.15 mmol.l-1) rose from day 25 after parturition.

Laboratory studies are an essential aspect in the management of children with grave diseases, helping to plan the therapeutic measures and to identify the disease. The most acute syndromes in pediatric emergency care are: coma, convulsions, dehydration, metabolic disequilibrium, hypovolemic or anaphylactic shock, a grave infection, chemical or drug poisoning. The laboratory tests that should be available within few minutes are blood cell count, blood and gas analysis, sodium, potassium, calcium, glucose measurements. The results of total proteins, serum creatinine and urea measurements, bleeding tests, analysis of blood smear, sedimentation rate, ALT, AST, osmolality, urinary electrolytes, creatinine and cerebrospinal fluid examinations should be available within sixty min. New accurate and rapid techniques and instruments facilitate the diagnostic and therapeutic approach to pediatric emergency.

The present study was undertaken to investigate the effects of acute 2,4-dichlorophenoxyacetic acid (2,4-D) intoxication (0.6 g/kg, po) on lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, amylase, creatinine, glucose, total protein and albumin levels in rats. Serum levels of lactate dehydrogenase, alkaline phosphatase and creatinine increased from 1- to 4-fold at 5, 8 and 24 h after 2,4-D administration, whereas serum levels of aspartate and alanine aminotransferase were higher only at 8 and 24 h. Amylase levels were only increased 8 h after administration of 2,4-D and then returned to normal levels. In contrast, 2,4-D reduced the serum levels of glucose and total protein 5, 8 and 24 h and serum albumin levels 5 h after herbicide intoxication. Thus, acute intoxication with 2,4-D disrupts serum levels of several enzymes and components which are considered to be indicators of tissue injury. Most likely these alterations mainly reflect hepatic and muscle tissue damage induced by the herbicide, but significant pancreatic and kidney toxicity may also have occurred.
