A 52-week oral repeated dose toxicity study of suplatast tosilate (IPD-1151T), a newly developed anti-allergic agent, was carried out in beagles by oral administration of 30, 90, 270 and 810 mg/kg/day for 52 weeks. The recovery study was carried out by the withdrawal for 5 weeks using control and the 810 mg/kg groups. The results are as follows: 1. Observation of general conditions revealed soft feces, mucous feces, and diarrhea in both sexes of the 270 and 810 mg/kg groups during the administration period, and these findings disappeared during the withdrawal period. One female of the 810 mg/kg group exhibited tremors in the legs and neck, staggering, a decrease of spontaneous motor activity, and clonic convulsions in Week 17 of administration and died on Day 118. One male of the same group exhibited whole body tremors and staggering from Week 32 to Week 52. 2. Body weight gain tended to be inhibited in males of the 810 mg/kg group during the administration period. The body weight of the female that died decreased rapidly after the appearance of neurological symptoms. The body weight of the male that exhibited neurological symptoms decreased after their appearance but later increased. 3. There were no abnormal changes in food consumption in all of the sacrificed dogs. The female that died did not eat at all after the appearance of neurological symptoms. The male that exhibited neurological symptoms did not eat at all for 1 week after their appearance, but the food consumption returned to normal thereafter. 4. Prothrombin times were prolonged in males of the 270 and 810 mg/kg groups at Week 26, and activated partial thromboplastin times were prolonged in males of the 810 mg/kg group at Week 52. 5. Plasma levels of alkaline phosphatase, GPT and LDH were elevated in some males and females of the 810 mg/kg groups. 6. No abnormalities due to IPD-1151T administration were found in urinalysis, opthalmological examination, electrocardiography, and fecal occult blood examination, or organ weights. 7. Autopsies including histopathological and electron microscopic examinations on the sacrificed dogs revealed no abnormalities. Subserosal hemorrhage in the base of the heart, congestion in the lungs, congestion and vacuolation in the liver and slight cell infiltration around vessels of the brain were found in the female that died.(ABSTRACT TRUNCATED AT 400 WORDS)

To investigate hemostatic changes after artificial valve replacement, I studied platelets, fibrinogen (Fbg), antithrombin III (AT-III), fibrinogen degradation products (FDP), thrombotest (TT), prothrombin time (PT), bleeding time (BT) and activated partial thromboplastin time (APTT) in 75 patients complicated with combined cardiac valvular disease. Twenty-nine patients with tricuspid regurgitation (TR group) and 46 patients without that (control group) were compared. 1) TR group, that contained patients with severer cases, showed a significantly longer operative time and greater bleeding volume than control group (p less than 0.01). 2) Many patients in TR group showed high serum II, frequency of abnormal platelet functions during and after extracorporeal circulation total-bilirubin and GPT level after operation and higher ICG R-value before operation than in control group. 3) After operation, the platelet count was significantly lower in TR group (p less than 0.01) than in control group, and was lowest on the 3rd postoperative day in both groups. 4) In both groups Fbg increased significantly after operation, and was lower in TR group on the 7th and 10th postoperative days than in control group. FDP was significantly higher in TR group than in control group after the 3rd postoperative day. 5) BT and APTT were similar in the two groups. 6) PT and TT were lower in TR group before operation (p less than 0.01) than in control group, and decreased after operation and administration of anticoagulants in both groups. These results indicate that patients with combined cardiac valvular disease with tricuspid regurgitation have a hemorrhagic tendency due to disorders of extrinsic coagulant, which may be caused by liver hypofunction, and are easy to bleed.

Fifteen Thai children, diagnosed with dengue hemorrhagic fever and admitted to the Children's Hospital in Bangkok, were studied. All cases were serologically proved to be secondary dengue infections. The clinical signs and symptoms in the first few days of the acute febrile phase were similar to those observed in cases with classical dengue fever, and included continuously high fever, headache, muscle pain, nausea, vomiting and abdominal pain, etc. In the laboratory findings we noted hypoalbuminemia and mild elevation of the GOT and GPT. The hemogram showed an increasing atypical lymphocyte count during the acute febrile period. Prolongations of the partial thromboplastin time and thrombin time were also found, especially in the severe shock cases. All patients had varying degrees of hepatomegaly and pleural effusion from their chest x-rays accompanied by a rapid increase in the hematocrit of more than 20% and a fall in the platelet count to less than 100000/microliters. During the plasma leakage period the patients easily developed shock, even leading to death, unless adequate fluid supplies were given. This is also the major pathophysiological difference between dengue hemorrhagic fever and classical dengue fever. Although some studies concerning the pathogenesis of dengue hemorrhagic fever have been reported, but the exact mechanisms need further investigation.

A 2-month-old boy was admitted to our hospital because of poor sucking and jaundice. There were no abnormalities during the whole period of pregnancy and at birth. His mother was a HBeAb positive HBsAg carrier, but prophylactic maneuver such as anti-HB immunoglobulin and HB vaccine was not performed on him at birth. Physical examination on admission revealed mild disturbance of consciousness. The laboratory findings showed marked increments of serum bilirubin, GOT, GPT, and NH3, and prolongation of prothrombin time, activated partial thromboplastin time and hepaplastin test. Thus, he was diagnosed as fulminant hepatitis and treated with exchange transfusion once or twice a day. Biochemical data improved gradually, but hypocoagulable states remained unchanged. At that time we decided to use Factor VII concentrate, because we found that, among several coagulation factors, factor VII activity decreased most rapidly after exchange transfusion. The alternate therapy of exchange transfusion and Factor VII concentrate improved his coagulation abnormality without any side effects. Our experience suggests that the combination therapy of exchange transfusion and Factor VII concentrate may be useful for management of fulminant hepatitis, particularly for uncontrollable coagulopathy.

Infected patients with hematological disorders were treated with the combination of cefmenoxime (CMX) and cefsulodin (CFS). This therapy was done on 74 patients, of whom 38 (51%) had acute myelocytic leukemia, 14 (19%) malignant lymphoma, 7 (9%) acute lymphocytic leukemia, 5 aplastic anemia, 4 adult T cell leukemia, 4 chronic myelocytic leukemia, 1 multiple myeloma and 1 histiocytic medullary reticulosis. Complicated infections included 5 cases of septicemia, 41 cases of suspected septicemia, 19 cases of respiratory tract infection, 2 with anal abscess, 1 with urinary tract infection and others. The obtained results were as follows: Clinical effectiveness of the combination therapy was excellent in 17 cases (23.0%), good in 24 (32.4%) and poor in 33 (44.6%). Total clinical efficacy rate was 55.4%. Clinical efficacy rate was 40% against septicemias, 51.2% against suspected septicemias and 57.9% against respiratory tract infections. Causative pathogens were isolated in only 21 cases (28.4%): Gram-positive bacteria in 9 cases, Gram-negative bacteria in 11 and fungus in 1. About half of the Gram-negative bacteria belonged to Pseudomonas sp. The efficacy rate of this combination therapy against Gram-negative bacterial infections was 72.7% but the rate against Gram-positive bacterial infections were only 33.3%. Only in 1 case, this combination therapy was discontinued because of drug eruption. Abnormal laboratory findings were observed in 5 cases: Elevation of BUN in 3, GOT and GPT in 1 and prolongation of activated partial thromboplastin time in 1. In conclusion, this combination therapy of CMX and CFS is useful and safe against infections complicated by hematological disorders.

We analyzed historical control data of clinical pathology testings provided by sixty-seven member companies of the Japan Pharmaceutical Manufacturers Association covering study populations of approximately 7,000 rats/sex, 5,000 dogs/sex, and 700 monkeys/sex. This paper assesses the relationship between conditions of sample collection, methods of measurement, etc. and potential factors contributing to variations in reference data, based on weighted means and standard deviations thereof derived from data for rats, dogs and monkeys for those parameters measured using methods most common to the participating facilities. Parameters included erythrocyte count (RBC), hematocrit (Ht), hemoglobin concentration(Hb), reticulocyte count (Rt), platelet count, total leukocyte count (WBC), differential leukocyte count (%WBC), coagulation time (activated partial thromboplastin time: APTT, prothrombin time: PT), and serum/plasma levels of GOT, GPT, ALP, LDH, glucose, cholesterol, triglycerides (TG), total protein, albumin, urea nitrogen (UN), creatinine, sodium (Na), potassium (K), calcium (Ca), chloride (Cl), inorganic phosphorus (Ip), and CPK. Analyses of the data revealed species differences in RBC, Ht, Rt, platelet count, WBC, %WBC, ALP, LDH, glucose, cholesterol, TG, total protein, UN, creatinine, Ca, Ip, and CPK. There were strain differences in rats in platelet count, WBC, GOT, ALP, UN, creatinine, and CPK. Sex differences were noted for Hb, Ht, WBC, ALP, glucose, cholesterol, TG, total protein, A/G ratio, UN, and Ip. Age differences were observed with RBC, Hb, Ht, Rt, %WBC, GOT, GPT, ALP, LDH, cholesterol, TG total protein, Ip, and CPK. APTT, PT, ALP, glucose, TG and UN were found to be subject to the influence of fasting/feeding. In rats, Ht, WBC, CPK and K showed differences by the site of bleeding. Observed values for LDH and CPK varied with specimen type, plasma or serum; serum assay values showed greater variation than plasma values.

A 33-year-old man presented malar rash in April, 1992. The rash had gradually developed and he was admitted to our hospital in February, 1994. Laboratory findings showed proteinuria of 0.5-0.8 g/ day, thrombocytopenia (4.8 x 10(4)/mm3), false positive serologic test for syphilis, anti-nuclear antibody with a speckled type at a titer of 1 : 80. Activated partial thromboplastin time was prolonged (41.3 s), and anti-beta 2-GPI antibody was strongly positive (56.6 U/ml on enzyme linked immunosorbent assay). The diagnosis of systemic lupus erythematosus with antiphospholipid syndrome was made and prednisolone 60 mg/day improved his manifestations. He could be discharged in July, 1994. Nine months after the discharge he developed dyspnea, and he was admitted to our hospital again. On admission the blood pressure was 212/170 mmHg, Levine III/VI systolic murmur was noted at the apex of heart. Significant laboratory findings showed as follows: WBC 15, 110/mm3 (Neu 73%, Lym 18%), RBC 380 x 10(4)/mm3, Hb 10.2 g/dl, Plt 20.0 x 10(4)/mm3, GOT 23 IU/l, GPT 21.

The natural compounds which affect defensive mechanisms of organism are important in prophylaxis and therapy of diseases in human and animals. Lysozyme is an enzyme which originates from chicken egg proteins. It modulates non-specific and humoral immunological mechanisms. A higher bioactivity has a lysozyme dimmer. The aim of study was assessment of influence of the lysozyme dimmer on chosen blood parameters, morphology and functions of internal organs and healing processes of experimental wounds in rabbits. Lysozyme dimmer (KLP-602) was used obtained process polymerisations enzyme lyzosyme from chicken egg white. The experimental group were on New Zealand White rabbits. Systemic reactions were investigated in animals after two injections of lysozyme dimer in dose 0,02 mg/kg b.w. during 21 days. Blood was collected before and after administration of lysozyme dimer in 4, 6, 24 h and in 3, 7, 21 day after first and in 4, 24 h and 3, 7 day after second injection. The following parameters were evaluated of red blood cells number (RBC), hemoglobin concentration (HGB), haematocrit value (HCT), red blood cell indices (MCV, MCH, MCHC), white blood cells number (WBC) and leukogram. Total serum proteins, components C3 and C4 of complement, immunoglobulins G and M, concentration were determined in the serum. Activated partial thromboplastin time (APTT), prothrombin time (PT) and fibrinogen concentration were evaluated in the plasma. Simultaneously, the activity of alkaline phosphatate, GPT and GOT were assessed. Administration rabbits with lysozyme dimmer caused slight decrease in RBC number, Hb concentration, HCT and the neutrophils percentage and increase in the lymphocytes percentage. The concentrations of TSP, immunoglobulins, the components of complement ware increased too. APTT an PT were normal but the fibrinogen concentration was increased. The activity of GOT and GPT were unchanged. Changes are in range of value normal and step out more quickly after two injection than after firste injection. The morphology of organs (liver, lungs, heart and kidneys) was normal.
