Four group systems of serum proteins (Hp, Gc, Gm, Km) and five group systems of erythrocyte enzymes (AP, PGM1, GPT, AK, EsD) were determined in 63 patients with malignant lymphoma. Statistical analysis of the distribution of the above mentioned systems in patients and Polish population samples did not reveal any significant differences, which points to the lack of any correlation between the disease and the group systems under examination.

111 chemicals of known rodent carcinogenicity (49 carcinogens, 62 noncarcinogens), including many promoters of carcinogenesis, nongenotoxic carcinogens, hepatocarcinogens, and halogenated hydrocarbons, were selected for study. The chemicals were administered by gavage in two dose levels to female Sprague-Dawley rats. The effects of these 111 chemicals on 4 biochemical assays (hepatic DNA damage by alkaline elution (DD), hepatic ornithine decarboxylase activity (ODC), serum alanine aminotransferase activity (ALT), and hepatic cytochrome P-450 content (P450)) were determined. Composite parameters are defined as follows: CP = [ODC and P450), CT = [ALT and ODC), and TS = [DD or CP or CT]. The operational characteristics of TS for predicting rodent cancer were sensitivity 55%, specificity 87%, positive predictivity 77%, negative predictivity 71%, and concordance 73%. For these chemicals, the 73% concordance of this study was superior to the concordance obtained from published data from other laboratories on the Ames test (53%), structural alerts (SA) (46%), chromosome aberrations in Chinese hamster ovary cells (ABS) (48%), cell mutation in mouse lymphoma 15178Y cells (MOLY) (52%), and sister-chromatid exchange in Chinese hamster ovary cells (SCE) (60%). The 4 in vivo biochemical assays were complementary to each other. The composite parameter TS also shows complementarity to all 5 other predictors of rodent cancer examined in this paper. For example, the Ames test alone has a concordance of only 53%. In combination with TS, the concordance is increased to 62% (Ames or TS) or to 63% (Ames and TS). For the 67 chemicals with data available for SA, the concordance for predicting rodent carcinogenicity was 47% (for SA alone), 54% (for SA or TS), and 66% (for SA and TS). These biochemical assays will be useful: (1) to predict rodent carcinogenicity per se, (2) to 'confirm' the results of short-term mutagenicity tests by the high specificity mode of the biochemical assays (the specificity and positive predictivity are both 100%), and (3) to be a component of future complementary batteries of tests for predicting rodent carcinogenicity.

In a 47-year-old male patient a tonsillar swelling was pointed out in May, 1991. Lymph node biopsy revealed that he had malignant lymphoma (diffuse large cell type). He had no hepatic dysfunction on admission, but because of positive hepatitis B (HB) antigen and negative HB antibody, he was diagnosed as an asymptomatic HB carrier. The staging examination showed that he had stage IIA lymphoma. Treatment with the COP-BLAM regimen was initiated on June 8. But the level of serum GOT and GPT increased to 286 IU/l and 392 IU/l, respectively. Serum DNA polymerase also increased to 9492 cpm. Interferon-alpha (3 x 10(6) units daily) was administered intramuscularly from June 8. Serum DNA polymerase decreased to zero on September 2, and his HBe antibody became positive indicating seroconversion. COP-BLAM chemotherapy without prednisolone was initiated from September 9 and complete remission was achieved. He was discharged from our hospital on September 25. It has been frequently reported that asymptomatic HB antigen carriers developed fulminant hepatitis during the course of chemotherapy. Our case suggests that it is necessary to continue chemotherapy in order to attain seroconversion by early use of interferon-alpha, when lymphoma patients display aggravated hepatic dysfunction and increased DNA polymerase levels.

The effect of a muramyl dipeptide derivative (B30-MDP) on the augmentation of antitumour immunity against highly metastatic L5178Y-ML25 mouse lymphoma cells was examined in CDF1 (Balb/c x DBA/2) mice. Mice immunized with a mixture of X-irradiated tumour cells (10(3)) and B30-MDP (100 micrograms) on 7 days prior to challenge by viable tumour cells displayed a significant decrease in metastasis towards the target organs, liver and spleen, compared with that of untreated mice. Immunization of mice with the mixture on day 5 or 7 after tumour challenge, when the level of glutamic-pyruvic transaminase (GPT) and glutamic-oxaloacetic transaminase (GOT) in sera of mice inoculated with viable tumour cells was observed to be normal, caused less metastasis than immunization with X-irradiated tumour cells alone. Sensitization with X-irradiated tumour cells admixed with B30-MDP induced almost two times higher cytotoxicity of spleen cells against L5178Y-ML25 lymphoma cells than sensitization with X-irradiated tumour cells without B30-MDP. In contrast, cytotoxic activity of spleen cells against another target, L1210 lymphoma cells derived from BDF1 mice, was not observed by immunization with X-irradiated L5178Y-ML25 cells with or without B30-MDP. Specific lysis by splenic cells of the immunized mice against L5178Y-ML25 cells decreased to the normal level when T cells were deleted from the immunized spleen cells by the treatment of rabbit anti-mouse Thy1.2 antibody and rabbit complement. These results indicate that B30-MDP is able to augment a specific tumour immunity due to the enhancement of cytotoxicity mediated by T lymphocytes, and is useful as an immunopotentiating agent for active immunization of inactivated tumour cells.

Fifty patients with infections associated with hematological disorders were treated with ceftazidime (CAZ). Among them 44 cases were evaluable, including 21 with acute leukemia, 17 with malignant lymphoma, and 6 with other hematological disorders. Excellent responses were observed in 15 patients (34.1%) and good responses in 15 (34.1%), with an overall efficacy rate of 68.2%. The efficacy rate among sepsis and suspected sepsis cases was 67.6%. This treatment was also effective in 7 of 10 cases in which neutrophil counts were less than 500/mm3 through the course of administration. Laboratory abnormalities included mild eosinophilia in 1 case, slight elevation of GOT in 1 case and slight elevation of GPT in 1 case. These results suggest that CAZ is an effective and safe antibiotics for the treatment of infections in patients with hematological disorders.

A 26 year-old man, who was treated for meningitis in our hospital previously, was rehospitalized 1 year later because he developed disturbance of consciousness, gait disturbance and urinary incontinence. Blood examination revealed accelerated ESR, elevated GPT, slight elevation of serum Ca, strong positive CRP, and a decrease in PHA and Con A. ACE was within normal range and tuberculin reaction was negative. Lumbar puncture revealed that the initial pressure was 310 mmH2O, cells were 152/3, and protein was 343 mg/dl. Bilateral hilar lymphadenopathy was absent in chest X ray film. Head CT revealed enlarged lateral ventricles and irregularly enhancing nodular lesions in the anterior half of the falx cerebri, and abnormally strong enhancement of the choroid plexus. Ventriculoperitoneal shunt was performed. As a diagnosis was difficult to obtain from the clinical data, biopsy of the nodular lesions was performed. The histopathologic diagnosis was sarcoidosis. Steroid hormone was administered thereafter, and the nodular lesions of the falx disappeared in the follow-up. In the literature, only 8 cases of sarcoidosis of the dura mater have been reported. Since intracranial sarcoidosis is a part of systemic sarcoidosis, its diagnosis is not difficult in most cases. However, in cases difficult to diagnose as in our case, biopsy may be necessary. When nodular lesion occurs in the dura mater, sarcoidosis must be included as a possibility in the differential diagnosis in addition to the usual meningioma, lymphoma, and metastatic brain tumor.

A 17-year-old male patient with T-cell type lymphoblastic lymphoma in complete remission underwent high dose chemotherapy (busulfan 16 mg/kg and cyclophosphamide 120 mg/kg) followed by autologous bone marrow transplantation (ABMT). The patient had been taking oral acyclovir (200 mg x 5) daily from seven days prior to the ABMT (day -7). On day +24, he complained of epigastralgia and general malaise, and the next day his GOT and GPT rose to 570 U/l and 397 U/l, respectively. Although he had no mucocutaneous lesions, hepatitis caused by a herpes virus was suspected, and high dose intravenous acyclovir (10 mg/kg x 3/day) was immediately started. His GOT, GPT and total bilirubin reached peaks of 2,870 U/l on day +26, 1,830 U/l on day +27 and 10.3 mg/dl on day +39, respectively, and rapidly improved thereafter. Serological analyses on IgG antibody titers to herpes simplex virus type 1 using an enzyme-linked immunosorbent assay revealed specific increases (454-fold before transplantation to 3,830-fold on day +46). Antiviral antibody titers to cytomegalovirus, varicella-zoster virus and Epstein-Barr virus showed no significant changes. The serologic markers of hepatitis B virus, hepatitis A virus and hepatitis C virus were all negative. The results indicate the patient's severe icteric hepatitis to have been caused by a reactivation of herpes simplex virus type 1 due to immunosuppression after high dose chemotherapy with ABMT. It is suggested that prompt commencement of high dose intravenous acyclovir is required to treat severe herpes simplex virus hepatitis affecting immunocompromised patients.

Prognostic factors in 47 patients with pleural lymphocytic lymphoma developing in chronic tuberculous pyothorax were evaluated using Cox's proportional hazards model. There were 41 men and six women, aged 44-80 (median 61) years. Approximately 70% of the patients had localized disease in Stages I and II, and 30% advanced disease in Stages III and IV. Histologically, 27 patients had the diffuse large, immunoblastic type and 12 had others. In the other seven patients, histological subtyping of the lymphocytic lymphoma was impossible because of degenerative or necrotic changes in the histologic specimens. A diagnosis of lymphocytic lymphoma of B-cell type was made in one case using combined cytologic and surface maker findings on a cell suspension. In addition, immunologic and immunohistochemical studies revealed another 40 cases to be proven B-cell lymphomas. Poor performance status and elevated levels of BUN and GPT were significantly associated with shortened survival in a Cox's proportional hazards model. A poor performance status and high levels of serum BUN and GPT suggested a marked deterioration in a patient's condition. When compared with previous literature describing prognostic factors in patients with B-cell lymphomas and with lymphocytic lymphomas with unfavorable histologies or associated with long-standing inflammations, the only common prognostic factors was performance status. The significance of primary site in predicting survival from lymphocytic lymphoma is discussed.

The effectiveness of sulbactam/cefoperazone (SBT/CPZ) on severe infections associated with hematological diseases was evaluated in a nation-wide multicenter clinical study. SBT/CPZ (4-6 g/day), a 1:1 combination of SBT and CPZ, was given intravenously to 437 patients with hematological disorders. The underlying diseases included acute nonlymphocytic leukemia, acute lymphocytic leukemia, malignant lymphoma, multiple myeloma, myelodysplastic syndrome and others. Thus, 94.3% of the patients had hematological malignancies. The complicating infections included sepsis in 41 cases; sepsis suspected in 205; pneumonia in 47; urinary tract infection in 15; fever of unknown origin in 59; and others in 70. Clinical efficacies of SBT/CPZ were as follows; markedly effective, 83 cases; effective, 170; fairly effective, 59; and ineffective, 110. The efficacy rate (markedly effective plus effective) was 60.0% as a whole. The efficacy rate of SBT/CPZ in sepsis and suspected cases, which accounted for 56.3% of the infections, was 59%. Mild side effects such as skin rash were observed in 15 patients (3.1%). As for abnormal laboratory test results, transient increases in GOT, GPT, A1-P, LDH, etc. were observed in 42 patients (8.6%). Therefore, SBT/CPZ is considered to be a useful drug in empiric therapy for severe infections associated with hematological diseases.

Among 30 consecutive patients diagnosed with primary biliary cirrhosis (PBC) in Taiwan, 27 were females and the median age of symptom onset was 54.5 years. Most had similar clinical manifestations to those reported in the Western countries, but ascites and oesophageal varices as commonly found at the late stages of cirrhosis of liver were noted in nine patients (30%) and 13 patients (43%) respectively. Only one patient was asymptomatic. Hyperbilirubinaemia was noted in 21 patients (70%) and hypoalbuminaemia in 8 patients (27%). All patients had elevated serum alkaline phosphatase and alanine aminotransferase and 28 (93%) had antimitochondrial antibodies. Ten out of 21 patients (48%) were positive in antinuclear antibodies, of which most were of speckled type. Sixteen out of 18 patients (89%) had elevated serum IgM levels. Interestingly, only one of 26 patients (3.8%) was positive for hepatitis B surface antigen, in contrast to its high prevalence (15%) in the Taiwan population. Special associated diseases, including systemic lupus erythematosus, scleroderma, malignant lymphoma and hepatocellular carcinoma, were each noted in one patient respectively. Eight patients had a history of gallstones before the diagnosis of PBC. The mean follow-up period was 23.6 +/- 19.8 months, and nine patients died during that period. In conclusion, the clinical manifestations of PBC in Taiwan are similar to those in Western countries, but most of our cases were at later stages.
