A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

Toxicological effect of 3-chloro-1,2-propanediol on rats were studied to provide scientific basis for assessing the effect of Chloropropanols on human health. 170 SD rats were divided randomly into 8 groups and the dose of 0, 0.25, 0.5, 1.0, 2.0, 4.0, 8.0, 16.0 mg/kg 3-chloro-1,2-propanediol were given to rats for 90 days by gavages per day, respectively. The weight and food efficiency, hematology and clinical chemistry, NAG, GGT and total protein in urine, sperm number, sperm survive rate and sperm aberration rate, the LDH and LDH-X activity in testis, rate of organ/weight and histopathological analysis were measured. The results showed that different dose of 3-chloro-1,2-propanediol did not has adverse effect on body weight, food efficiency, Hb, red cell, white cell, serum AST, ALT, creatine, ALP, LDH, total protein and albumin, urine GGT and total protein, LDH activity in testis. At the dose of 4.0, 8.0 and 16.0 mg/kg group, the activity of NAG in urine and the rate of kidney/weight was significantly increased compared with negative control groups; the pathological changes in kidney were observed in the same groups, and the sperm number was also significantly decreased. At the dose of 8.0 and 16.0 mg/kg group, sperm survive rate and the X-LDH activity were significantly decreased and pathological changes were also observed in testis and caudal epididymis. It was concluded that the activity of NAG in urine and sperm number is the sensitive biological effective marker. Because urine is a kind of convenient available biological material, NAG activity in urine is a good biological effective marker for assessing effect of Chloropropanols on health. If the NAG activity can be used as sensitive marker for assessment on human health need to be tested further in human study.

Wilson's disease (WD) is a rare liver-based disorder of copper metabolism. Prognostic criteria described by our group in 1986 to predict death without transplantation have not been universally validated. The clinical features of 88 children were reviewed, retrospectively in 74 and prospectively in 14. Data from the retrospectively recruited patients that died or survived on long-term chelation were used to evaluate the validity of our old scoring system and to devise a new prognostic index, then assessed in the 14 prospectively recruited patients. Using the old scoring system, 5 children scoring > or = 7, the cutoff value for death without transplantation, survived, whereas 4 scoring < or = 7 died (sensitivity 87% and specificity 90%). A new index based on serum bilirubin, international normalized ratio, aspartate aminotransferase (AST), and white cell count (WCC) at presentation identified a cutoff score of 11 for death and proved to be 93% sensitive and 98% specific, with a positive predictive value of 88%. When the new index was evaluated prospectively in 14 patients, it predicted the need for transplantation in only the 4 who required it, although 1 child with a score of 11 survived on medical treatment. In conclusion, the new Wilson Index is more sensitive and specific in predicting mortality without transplantation than the old scoring system, but needs to be validated in a larger number of patients.

The right lobe liver graft has become the workhorse of adult-to-adult live donor liver transplantation. Donor right hepatectomy is feasible only because of the immense regenerative ability of the liver. The long-term biological consequences of this very major donor procedure on the donor however are unknown. Twenty-nine donors of this procedure in our centre, all of whom included the middle hepatic vein, were studied. On long-term follow-up at a median of 47.4 months, there was a discernible but statistically insignificant decrease in size of the regenerated left lobe compared to the original whole liver volume. There was paradoxically a trend of incompleteness of regeneration in relation to the original liver volume for those with a larger remnant left lobe. The volume ratio of the regenerated left lobe to the original left lobe before hepatectomy was inversely proportional to the left lobe proportion preoperatively. This strong but inverse linear correlation reflected the good regenerative ability of the remnant left lobe. None of the donors developed thrombocytopenia. Although demonstrable decrease in white cell count, increase in serum alanine aminotransferase, aspartate aminotransferase, and creatinine did occur, the changes remained within normal limits and were of yet uncertain clinical significance. In conclusion, donor right hepatectomy including the middle hepatic vein is biologically acceptable to the live donor.

Monitoring of changes in some blood laboratory parameters in 34 horses after ingesting freshly harvested maize that was to be used for ensiling, heavily contaminated with young Datura stramonium plants, is described. For a 7-day period the following parameters were monitored: haemoglobin content (HGB), red blood cell counts (RBC), white blood cell counts (WBC), haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), differential white cell counts (DWC), erythrocyte sedimentation rate (ESR), protein fractions, aspartate aminotransferase (AST), lactate dehydrogenase (LDH), total bilirubin (TB), direct bilirubin (DB), blood glucose (Glu), total protein (TP), globulin (Glob) and albumin (Alb). The intoxication was accompanied by erythrocytosis, leukocytosis, regenerative left shift neutrophilia, lymphopaenia, eosinopaenia, increased haematocrit values, low erythrocyte sedimentation rate, hyperglycaemia, bilirubinaemia, hypoproteinaemia and increased activity of AST and LDH. No changes occurred in the mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), albumin, globulin and globulin fractions (alpha 1, alpha 2, beta 1, beta 2 and gamma). The blood parameters returned to normal between post-intoxication days 2 and 5. The observed changes in clinical chemistry indices could be used in the diagnosis, differential diagnosis and prognosis of Jimson weed intoxication.

The purpose of this work was to assess the clinical, haematological and biochemical responses of pigs experimentally inoculated with Trichinella spiralis. Groups of three pigs were inoculated per os with 100, 500 and 5000 T. spiralis muscle larvae, two pigs were used as control. Clinical evaluation of disease in pigs included daily examination, rectal temperature measurements and cardiac and respiration rates. Haematological studies included: hematocrit (%), hemoglobin (g/dl), and white cell, neutrophil, lymphocyte and eosinophil counts. Blood biochemistry included: bun (mg/dl), creatinine (mg/dl), AST (UI/l), ALT (UI/l), CPK (UI/l) and ALP (UI/l). No significant differences were observed in rectal temperature and in cardiac and respiration rates between inoculated animals and the control group (p> or =0.05). Significant differences were detected (p< or =0.05) in the values of % hemoglobin, and eosinophils, as well as in the values of CK, ALP, AST and ALT. The variations observed in some cases were related to the number of T. spiralis larvae inoculated and varied with the number of days post-infection. Inoculated pigs showed significant differences (p< or =0.05) in weight gain when compared with uninoculated controls. This study has clinical, haematological, and enzyme alterations in Trichinella infected pigs provides a better understanding of acute and chronic trichinellosis in pigs.

Racial differences in response to treatment of hepatitis C virus (HCV) have been noted in several trials. In this study, we compared the response rate to treatment of Asian patients infected by genotype 3 HCV with non-Asians treated for the same genotype. Sixteen of 38 (42.1%) Asians achieved a sustained virological response (SVR), compared with 41 of 66 (62.1%) Caucasians (P = 0.063). At baseline prior to treatment, Asians had a higher histological fibrosis stage (P = 0.0014), indicating more advanced disease at presentation. In univariable analysis of baseline factors predicting failure to achieve an SVR, Asian ethnicity, fibrosis stage, higher serum aspartate transaminase, bilirubin and alkaline phosphatase, as well as lower white cell count, haemoglobin and platelet count were statistically significant. None of these factors achieved significance in multivariate analysis, possibly because of the relatively small number of patients studied. We have observed an inferior response to treatment of Asian vs Caucasian patients. The poor response probably reflects the more advanced liver disease at baseline observed for Asian British patients.

Health and nutritional assessments of wildlife are important management tools and can provide a means to evaluate ecosystem health. Such examinations were performed on 37 white-fronted brown lemurs (Eulemur fulvus albifrons) from four sites in Madagascar. Comparison of health parameters between sites revealed statistically significant differences in body weight, body temperature, respiratory rate, hematology parameters (white cell count, hematocrit, segmented neutrophil count, and lymphocyte count), serum chemistry parameters (aspartate aminotransferase, alanine aminotransferase, serum alkaline phosphatase, total protein, albumin, phosphorus, calcium, sodium, chloride, and creatinine phosphokinase), and nutrition parameters (copper, zinc, ferritin, retinol, tocopherol, and 25-hydroxycholecalciferol). Two of 10 lemurs tested were positive for toxoplasmosis; none of 10 were positive for Cryptosporidium or Giardia. Enteric bacteria and endo- and ectoparasites were typical. Statistically different values in hematology and chemistry values probably do not reflect clinically significant differences, whereas nutrition parameter differences are likely related to season, soil, and forage availability.

Clinicopathologic features of 45 patients with fulminant hepatic failure due to massive or submassive hepatic necrosis were studied. Both percutaneous biopsies and liver explants were available in 23 patients, whole livers only in 11 cases, and biopsies only in 11 cases. An etiologic diagnosis was established in 16 cases (36%). A further 3 cases (7%) were associated with aplastic anemia. Established etiologies included drug reactions (n = 7); autoimmune hepatitis, type 2 (n = 3); halothane hepatitis (n = 1); ischemia/hypotension (n = 1); mushroom poisoning (n = 1); mitochondrial disorder (n = 1); hemophagocytic lymphohistiocytosis (n = 1); and adenoviral hepatitis (n = 1). The extent of necrosis on liver biopsy correlated poorly with that in liver explants (mean difference, 32% +/- 23.8%). Almost all cases could be classified into one of 2 broad patterns of necrosis, namely, (1) zonal coagulative necrosis or (2) panlobular (nonzonal) necrosis. These patterns differed significantly with respect to several clinical parameters including sex ratio, peripheral blood white cell count, serum aspartate transaminase and alanine transaminase, conjugated bilirubin, and alkaline phosphatase levels. Livers with panlobular necrosis showed a spectrum of histopathologic findings that included central venulitis (76%), lymphocytic infiltration of large duct/gallbladder epithelium (54%), and syncytial giant cell transformation (18%). These features were not seen in livers with zonal coagulative necrosis which frequently showed prominent steatosis (91%). Both patterns of necrosis frequently showed ductular proliferation (100%) and cholangiolitis (80%). The diagnostic yield of ancillary studies (histochemistry, immunohistochemistry, and electron microscopy) was very low (<1%). The small proportion of cases with etiologic diagnoses precluded correlation of clinical and histopathological parameters with specific etiologies. In summary, this study describes the spectrum of changes seen in massive and submassive necrosis in children and identifies clinical features that might differentiate between 2 broad patterns of necrosis.

This study measured haematological and liver function parameters in workers occupationally exposed to cement dust in order to test the hypothesis that cement dust exposure may perturb these functions. Assessment of haematological parameters and liver function were performed in 23 workers occupationally exposed to cement dust (mean years of exposure 9.6+/- 1.5 years) and 46 matched unexposed controls. The haemoglobin concentration (P < 0.001) and packed cell volume (P < 0.02) of exposed workers were significantly lower and the platelet (P < 0.01) and white cell counts (P < 0.05) were significantly higher than in the unexposed workers. There was no significant difference in the total granulocyte and lymphocyte/monocyte counts. The liver function parameters remained similar in the exposed workers compared to the unexposed except serum aspartate aminotransferase and alkaline phosphatase activities which were significantly lower (P <0.05). These results suggest that occupational exposure to cement dust may perturb haemopoietic function while preserving liver function.
