Toxicosis was induced in pregnant Holstein-Friesian heifers by giving polybrominated biphenyls a in gelatin capsules at the rate of 25 g/day. Initially, this dosage was approximately 67 mg/kg of body weight. Clinical signs were anorexia, excessive lacrimation and salivation, diarrhea, emaciation, dehydration, depression, and abortion. Fever was not evident during the experiment. Values for serum glutamic-oxalacetic transaminase, lactic dehydrogenase, blood urea nitrogen, and bilirubin were increased. Changes in packed cell volume, hemoglobin content, total erythrocyte and leukocyte counts, and differential leukocyte counts were minimal and reflected dehydration and secondary infection. The principal urine changes were decreased specific gravity and moderate proteinuria. Gross necropsy findings included dehydration; subcutaneous emphysema and hemorrhage; atrophy of the thymus; fetal death with concomitant necrosis of cotyledons; kidneys that were enlarged, pale tan to gray; thickened wall of the gallbladder; inspissated bile; edema of abomasal folds; mucoid enteritis; linear hemorrhage and edema of the rectal mucosa; and secondary pneumonia. Microscopic changes were most marked in the kidneys, gallbladder, and eyelid. In the kidney, the principal changes were extreme dilatation of collecting ducts and convoluted tubules, with epithelial degenerative changes of cloudy swelling, hydropic degeneration, and separation from the basement membrane. Common changes in the gallbladder were moderate to marked hyperplasia and cystic dilatation of the mucous glands in the lamina propria. The changes in the eyelids were characterized by hyperkeratosis, with accumulations of keratin in hair follicles of the epidermis and squamous metaplasia with keratin cysts in the tarsal glands. Clinical signs and lesions of toxicosis did not develop in heifers given the polybrominated biphenyls at the rate of 0.25 mg and 250 mg/day for 60 days. Initially these rates were approximately 0.00065 mg/kg and 0.65 mg/kg of body weight, respectively.

Lumpy skin disease is an infectious viral disease of cattle, which often occurs in epizootic form. The disease is characterized by the eruption of nodules in the skin, which may cover the whole of the animal's body. Systemic effects include pyrexia, anorexia, dysgalactia and pneumonia; lesions are often found in the mouth and upper respiratory tract. The severity of the disease varies considerably between breeds and strains of cattle. Many cattle suffer severe emaciation and loss of production for several months. The skin lesions cause permanent damage to the hides. The mode of transmission of the disease has not been clearly established. Contact infections do not readily occur and the evidence from the epizootiology strongly suggests that insect vectors are involved. The disease has been confined to sub-Saharan Africa, until it recently appeared in epizootic form in Egypt and in Israel. Transmission occurs in a wide variety of biotypes, from semi-desert to temperate grasslands and irrigated land. It has the potential to extend its range further.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

Twelve one-day-old chicks were experimentally inoculated with Chlamydia psittaci derived from turkeys. Acute chlamydial septicemic lesions were induced by the inoculation into the air sac and trachea. No lesions were produced by the esophageal injection. Clinically, the affected chicks showed emaciation and mouth breathing, and were inactive while some birds died. Grossly, they had hepatomegaly, splenomegaly and airsacculitis. Histopathologically, fibrinopurulent airsacculitis, pneumonia and bronchitis, multiple fibrinous serositis in the hepatic and splenic capsules, peri- and epicardium, and mesenterium, focal endoarteritis in the aortae, activation of reticuloendothelial cells in the spleen, and hepatic necrosis were noted. Immunohistochemically, chlamydial antigen granules were present in the cytoplasm of epithelial cells of the respiratory system, hepatocytes, macrophages in the air sac, lung, serous membrane, liver, spleen, aortae, reticuloendothelial cells in the spleen, and mesothelial cells in various organs or tissues. Chlamydial multiplication in the cells of the organs or tissues involved was preceded to form the lesions.

Pasteurella multocida was isolated from 2 farms on which grower or finisher pigs had problems of severe emaciation and high death loss (greater than 5%). At necropsy, the pigs had extensive suppurative pleuritis and pericarditis, with adhesions over the lung surface. On one farm, the pigs also had multiple lung abscesses. Histologic findings included polymorphonuclear cell infiltration in bronchial and alveolar spaces, thickening of alveolar walls, pleuritis, and in some cases, abscesses. From all pigs, P multocida was isolated. The strains (A52, A59) were serotype A and were nontoxigenic. Experimental reproduction of the disease was achieved by sequentially infecting conventionally weaned pigs intranasally with pseudorabies virus; 7 days later, infection with selected P multocida laboratory strains (A50 and D82, A52 and A59) was achieved. At necropsy, pigs inoculated with strains A59 and A52 (serotype A, pleurotropic) had more severe lesions (P less than 0.05) than those inoculated with strain A50 (serotype A, pneumotropic). Also, pigs infected with strains A59 and A52 had extensive pleuritis and abscessation, which were not observed in the other groups. Strain D82 (serotype D) was not capable of producing pneumonia or pleuritis. Pleuritis and abscessation may be associated with certain P multocida strains that are serotype A, but not with others. These pleurotropic strains seem to be more virulent than pneumotropic strains, and infection with the former may result in extensive pleuritis and abscess formation.

In order to study the safety of 1,3,3,5,5-pentaziridino-1-thia-2,4,6-triaza-3,5-diphospho rine-1-oxide (SOAz), a new antitumor agent, acute toxicity studies by intravenous administration were performed in ddY mice, Wistar rats and beagle dogs. The LD50 values in rodents were 325 mg kg-1 for male mice, 450 mg kg-1 for female mice, 100 mg kg-1 for male rats and 82 mg kg-1 for female rats. In dogs, the LD50 values were 12 mg kg-1 for males and 18 mg/kg-1 for females. The dosed animals showed diarrhoea and decreased movement in the three species, and emaciation and loss of body weight in mice and rats. Dogs also showed signs of pneumonia. Histopathological examination revealed bone marrow suppression, atrophy of lymphoid organs and testes, and damage to the digestive tract mucosa in the three species. The main causes of death from single-dose administration were bone marrow aplasia and atrophy of lymphoid tissue in all species, together with gastro-intestinal ulceration in rats and dogs, and infection in mice and dogs.

At a follow-up study of 385 patients with epilepsy beginning under age 15, 22 (5.7%) had died during the first 10 years after the onset of epilepsy and another 11 (2.9%) between 11 and 24 years. Mortality was significantly high in cases with the following clinical features: (1) epilepsy with onset before the first birthday (mortality being 25.5%), (2) symptomatic epilepsy in etiology (17.2%), (3) infantile spasms (40.7%), tonic epilepsy (33.3%) or myoclonic epilepsy (33.3%) as compared with grand mal (5.9%) in seizure type and (4) developmental retardation at the first visit (25.5%). Seizures were not controlled in 31 out of 33 patients at the time of death. The causes of death were status epilepticus or convulsion in 10, pneumonia in 5, severe emaciation in 3, "cerebral palsy" in 5, and drowning, suffocation, traffic accidents or acute lymphocytic leukemia, in one each, and unknown in 6. Most of the patients died at home.

The immunosuppressive effect of FK506 (FK) in comparison to cyclosporine A (CsA) on lung graft rejection was demonstrated using 24 mongrel dogs with left lung allotransplantation. The cytotoxic activity of peripheral blood mononuclear cells was evaluated using donor skin fibroblasts. In eight dogs not given immunosuppression, the grafted lungs lost aeration 5-10 days postoperatively, and histologic findings revealed grade II rejection and cytotoxic activity elevated to between 10.7 and 60.5%, being an average of 31.2% at an effector/target (E/T) ratio of 50. Of 12 dogs treated with FK, none demonstrated a cytotoxic activity of 10% or more at an E/T ratio of 50. Moreover, histologic examinations of the specimens obtained by open chest biopsy revealed no signs of rejection during the first 10 postoperative days of FK administration, except in one dog showing grade I rejection from the FK 0.05 mg/kg group. A dose study of the duration until the onset of graft rejection and the elevation of cytotoxic activity after the termination of FK administration revealed approximately 1-2 weeks in the FK 0.05 mg/kg group, 3-4 weeks in the 0.1 mg/kg group, and later in the 0.4 mg/kg and 2.0 mg/kg groups. However, severe body weight loss was seen in the 0.4 mg/kg and 2.0 mg/kg groups postoperatively, without recovery even after the termination of FK. In fact, two dogs died of pneumonia possibly derived from general emaciation. These results suggest the optimal concentration of FK in canine lung allo-transplantation to be 0.1 mg/kg intramuscularly.

Six Indonesian buffaloes (Bubalus bubalis) were inoculated intravenously with 10(5) Trypanosoma evansi, examined clinically, haematologically and serologically, and then killed 1, 2, 3, 4, 8 or 12 weeks after infection for detailed pathological study. Relapsing fever was related to the waves of parasitaemia and fluctuations of pulse and respiration rates. Anaemic mucous membranes, depression, weakness, refusal to walk, loss of appetite and emaciation were seen. Body weight, packed cell volume, total platelet and red cell counts, and haemoglobin values were below those of two uninfected control buffaloes, as well as below the normal range; on the other hand antibody titres against T. evansi in infected animals were all above those in controls. Emaciation, serous atrophy of fat, hydropericardium, petechial to larger haemorrhages in the pericardium, pneumonia, congested liver and spleen, oedematous enlargement of the superficial lymph nodes and hyperplastic bone marrow were the major gross pathological changes. Histologically, the severity of the disease increased from 1 to 7 weeks after infection and became less obvious at 12 weeks. The most consistent lesions were interstitial pneumonia, interstitial myocarditis, splenic multifocal necrosis, interstitial myositis and hyperplastic bone marrow. The last three lesions appear not to have been reported previously in T. evansi infection in buffaloes or other animals. The clinicopathological findings in this study show that T. evansi is both an intravascular and extravascular parasite.
